Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 14/692,351, filed on Apr. 21, 2015, which
claims priority to Chinese Patent Application No. 201410165238.X,
filed on Apr. 23, 2014. All of the afore-mentioned patent
applications are hereby incorporated by reference in their
entireties.
TECHNICAL FIELD
[0002] The present disclosure relates to the communications field,
and in particular, to an information sending method, a network
device, and a terminal.
BACKGROUND
[0003] When help is needed in an emergency, generally, a help
seeker contacts a 110 alarm center by phone, and then, the police
arrive at the site of the emergency for rescue. A problem of help
seeking in this way is that it may be a relatively long time from
the reporting to the arrival of the police at the site, and
therefore, the best opportunity for rescue is easily missed.
[0004] In the prior art, some help-seeking methods are also
provided.
[0005] For example, a help-seeking method is that a mobile phone
with a calling-for-help function is provided and includes a toggle
key that is configured to trigger a calling-for-help system; the
toggle key is connected to a general-purpose input/output (GPIO)
interface of a central processing unit (CPU) of the mobile phone;
and after the CPU of the mobile phone receives a trigger signal,
positioning is performed using an Assisted Global Positioning
System/Global Positioning System (AGPS/GPS) chip of the mobile
phone, and collected location information is sent by the CPU of the
mobile phone to a mobile phone with a preset phone number.
[0006] In this method, after a user triggers help seeking using the
toggle key, the mobile phone sends the location information of the
user to the mobile phone with the preset phone number. However, if
the mobile phone with the preset phone number is not started, or
when the mobile phone with the preset phone number is relatively
far from the help seeker, even though help-seeking information
including a location is sent, the help seeker cannot get help in
time.
[0007] For example, another help-seeking method is that WeChat
software is installed in a mobile phone, and when a user shakes the
mobile phone, the WeChat software uploads a mobile number, base
station information, and GPS information of the user to a server;
and the server immediately calculates information that other users
shake mobile phones, which is received within N seconds before a
request that the user shakes the mobile phone is received, and
performs matching according to distances, and then returns a result
to the user. Specific steps are as follows.
[0008] 1. Implement a shake function, where an acceleration sensor
is used. When the acceleration sensor detects that the mobile phone
of the user is shaking, a request is sent to a nearby mobile phone
base station.
[0009] 2. A nearby mobile phone base station with the best signal
quality receives the request of the user, and generally a distance
between the base station and the mobile phone of the user ranges
from 50 to 100 meters. For example, a serial number of the base
station is W203000, where all mobile phone base stations are
uniquely numbered; and a physical address of a location of the
mobile phone base station may be found out according to the serial
number of the base station.
[0010] 3. The mobile phone base station uses its location as a
current location of the user, and sends the location to a WeChat
background server.
[0011] 4. If detecting that multiple persons are at a same
location, the WeChat background server pushes to the user persons
nearby.
[0012] However, WeChat is a social chat tool, and is only used to
push other persons nearby to a user. When needing help, the user
still needs to contact the persons nearby one by one. The method is
not an automatic help-seeking method, has relatively low execution
efficiency, and obviously, cannot be applied to an emergent
help-seeking scenario.
[0013] It can be seen that, there is no relatively effective
help-seeking method in the prior art.

DESCRIPTION OF EMBODIMENTS
[0070] The information sending method in the embodiments of the
present disclosure may include receiving, by a first network
device, alarm information sent by an alarm terminal; and after
confirming the alarm information, generating, by the first network
device, first guide information according to the alarm information,
and sending the first guide information to a target terminal, so
that the target terminal can respond to the alarm information
according to the first guide information, where the target terminal
is a terminal selected from terminals that are within same
base-station signal coverage in which the alarm terminal is
located, or the target terminal is a terminal selected from
terminals whose distances from the alarm terminal are less than a
threshold.
[0071] In the embodiments of the present disclosure, after
receiving the alarm information, the first network device may
generate the first guide information and send the first guide
information to the target terminal. In this way, the target
terminal may respond to the alarm information, and help rescue a
user of the alarm terminal. Because the target terminal is a
terminal selected from terminals that are within same base-station
signal coverage in which the alarm terminal is located, or the
target terminal is a terminal selected from terminals whose
distances from the alarm terminal are less than a threshold, which
means that a distance between the target terminal and the alarm
terminal is relatively short, so that the target terminal can
arrive at the site in time to rescue the user of the alarm
terminal, thereby effectively improving rescue efficiency. The
first network device automatically sends the first guide
information to the target terminal, where there may be one or more
target terminals, and the alarm terminal does not need to send the
first guide information one by one; therefore, efficiency of
information transmission is relatively high, and it is ensured to
the greatest extent that the user of the alarm terminal can be
rescued in time.
[0072] To make the objectives, technical solutions, and advantages
of the embodiments of the present disclosure clearer, the following

embodiments are some but not all of the embodiments of the present
disclosure. All other embodiments obtained by a person of ordinary
skill in the art based on the embodiments of the present disclosure
without creative efforts shall fall within the protection scope of
the present disclosure.
[0073] Technologies described in this specification may be applied
to various communications systems, for example, current second
generation (2G) and third generation (3G) communications systems
and a next-generation communications system, for example, a Global
System for Mobile Communications (GSM), a Code Division Multiple
Access (CDMA) system, a Time Division Multiple Access (TDMA)
system, a Wideband Code Division Multiple Access (WCDMA) system, a
Frequency Division Multiple Access (FDMA) system, an Orthogonal
Frequency-Division Multiple Access (OFDMA) system, a single-carrier
FDMA (SC-FDMA) system, a General Packet Radio Service (GPRS)
system, a Long Term Evolution (LTE) system, and other
communications systems.
[0074] In addition, the terms "system" and "network" may be used
interchangeably in this specification. The term "and/or" in this
specification describes only an association relationship for
describing associated objects and represents that three
relationships may exist. For example, A and/or B may represent the
following three cases: Only A exists, both A and B exist, and only
B exists. In addition, the character "/" in this specification
generally indicates an "or" relationship between the associated
objects.
[0075] In the following, the embodiments of the present disclosure
are described in detail with reference to the accompanying drawings
of the specification.
[0076] Referring to FIG. 1, an embodiment of the present disclosure
provides an information sending method, and a main procedure of the
method is as follows.
[0077] Step 101: A first network device receives alarm information
sent by an alarm terminal.
[0078] For example, the first network device may be an alarm center
server. The alarm terminal includes, for example, a help-seeking
module; and a user triggers the help-seeking module, and the alarm
terminal may automatically send alarm (help-seeking) information to
the first network device.
[0079] Preferably, before, after, or when the first network device
receives the alarm information sent by the alarm terminal, the
method further includes that the first network device receives
location information of the alarm terminal that is sent by the
alarm terminal, where the location information of the alarm
terminal is obtained by the alarm terminal by means of
AGPS/GPS.
[0080] If the location information of the alarm terminal is
obtained by means of AGPS, the alarm terminal and a base station
need to jointly participate when the location information of the
alarm terminal is obtained.
[0081] That is, after detecting that the user triggers the
help-seeking module, the alarm terminal may acquire the location
information of the alarm terminal, and send the alarm information
and the location information of the alarm terminal to the first
network device using a radio communications system. The location
information of the alarm terminal may also be carried in the alarm
information; or, the location information of the alarm terminal may
be carried in other information for sending.
[0082] A manner in which the user triggers the help-seeking module
may include calling 110 using the alarm terminal, pressing an SOS
button on the alarm terminal, starting help-seeking software in the
alarm terminal, or the like.
[0083] After the alarm terminal detects that the help-seeking
module is triggered, if the alarm terminal has a positioning
module, a processor module of the alarm terminal reads the location
information of the alarm terminal using the positioning module. For
example, the positioning module may be a GPS module, and the
location information of the alarm terminal is, for example,
latitude and longitude information of the alarm terminal. If the
help-seeking module is triggered, but the positioning module is not
started yet, the processor module may activate the positioning
module.
[0084] The manner in which the user triggers the help-seeking
module may be sending a help-seeking request to the alarm terminal,
where the help-seeking request may be, for example, a real-time
voice call during which the alarm terminal dials the 110 number, or
may be information that is preset in the alarm terminal, or may be
a segment of voice information that the user dictates
temporarily.
[0085] Step 102: After confirming the alarm information, the first
network device generates first guide information according to the
alarm information, and sends the first guide information to a
target terminal, so that the target terminal can respond to the
alarm information according to the first guide information, where
the target terminal is a terminal selected from terminals that are
within same base-station signal coverage in which the alarm
terminal is located, or the target terminal is a terminal selected
from terminals whose distances from the alarm terminal are less
than a threshold.
[0086] Preferably, in this embodiment of the present disclosure,
after receiving the alarm information, the first network device may
first confirm the alarm information or put the alarm information on
a record. The confirming the alarm information may include
confirming the alarm terminal, or, confirming the alarm
information. The putting the alarm information on a record may
refer to recording the alarm information.
[0087] Preferably, that the first network device confirms the alarm
information may include that the first network device determines
whether the alarm information is valid alarm information, and the
first network device determines, according to information about the
alarm terminal that is carried in the alarm information, whether
the alarm terminal is an authorized terminal; and when the alarm
information is valid alarm information, and the alarm terminal is
an authorized terminal, the first network device confirms that
detection of the alarm information is passed.
[0088] For example, the information about the alarm terminal may
include an identifier of the alarm terminal. For example, a
whitelist may be stored on the first network device side, where the
whitelist may include identifiers of authorized terminals. The
first network device may look up, in the whitelist, whether the
whitelist includes the identifier of the alarm terminal; if the
whitelist includes the identifier of the alarm terminal, it
indicates that the alarm terminal is an authorized terminal, and if
the first network device confirms that the alarm information is
valid alarm information, the first network device may generate the
first guide information according to the alarm information; and if
the whitelist does not include the identifier of the alarm
terminal, it indicates that the alarm terminal is an unauthorized
terminal, the first network device may not respond to the alarm
information, or if the alarm information is invalid alarm
information, the first network device may not respond to the alarm
information, either. In this way, security of a network system may
be ensured to the greatest extent, and a malicious attack may be
avoided.
[0089] In addition, an identity of a user of the alarm information,
for example, may be further carried in the alarm information for
sending. The first network device may verify the identity of the
user and determine whether the user is an authorized user; if the
user is an authorized user, the first network device responds to
the alarm information; and if the user is an unauthorized user, the
first network device does not respond to the alarm information,
thereby avoiding fake alarm information.
[0090] After receiving the alarm information, the first network
device may generate the first guide information according to the
alarm information.
[0091] Preferably, before, after, or when the first network device
receives the alarm information sent by the alarm terminal, the
method may further include that the first network device receives
the location information of the alarm terminal that is sent by the
alarm terminal, where the location information of the alarm
terminal is obtained by the alarm terminal by means of
AGPS/GPS.
[0092] If the first network device receives the location
information of the alarm terminal that is sent by the alarm
terminal, that the first network device generates the first guide
information according to the alarm information, and sends the first
guide information to the target terminal may include that the first
network device generates the first guide information according to
the alarm information, and sends the first guide information to the
target terminal, where the target terminal is a terminal that is
determined, according to the location information of the alarm
terminal and the first guide information, among terminals that are
within same base-station signal coverage in which the alarm
terminal is located, or, a terminal that is determined, according
to the location information of the alarm terminal and the first
guide information, among terminals whose distances from the alarm
terminal are less than the threshold.
[0093] In this embodiment of the present disclosure, the first
guide information may be information of different types. For
example, the first guide information may be information including
help-seeking content, the first guide information may be
information including road guide content, or the like.
[0094] Preferably, in this embodiment of the present disclosure,
that the first network device generates the first guide information
according to the alarm information may include that the first
network device parses the alarm information, and determines a
meaning of the alarm information; and the first network device
generates the corresponding first guide information according to
the meaning of the alarm information.
[0095] For example, if the meaning of the alarm information is that
"a person falls into water and is rescued, but is in a coma", the
first network device may expect to find a rescuer who is near the
help seeker and can perform artificial respiration. Therefore, a
meaning of the first guide information generated by the first
network device may be that "a person nearby falls into water and is
rescued; and if you are familiar with artificial respiration,
please offer help at once". It can be seen that, in this embodiment
of the present disclosure, the first network device can translate
the alarm information of the user into an explicit rescue
requirement, so that a user using the target terminal can directly
grasp the requirement of the help seeker, thereby offering rescue
as soon as possible.
[0096] For example, a manner of parsing the alarm information may
be performing semantic parsing on a text of the alarm information,
where the semantic parsing may be determining, based on
identification samples between words (phrases) recorded in a
database, a meaning of a segment of the text according to a
statistical language model and the identification samples. Further,
the first network device may store a semantic comprehension
template, and the alarm information is directly mapped to the first
guide information according to the meaning of the alarm
information. Table 1 shows a mapping relationship, where keywords
are all those included in the alarm information.
TABLE-US-00001 TABLE 1 Keyword 1 Keyword 2 First Guide Information
Fall into Seek help At xxx site, a person falls into water. A
nearby water swimmer, please offer help as soon as possible. Fall
into Breathe/ At xxx site, a person falls into water and is water
Coma rescued. A nearby rescuer who can perform artificial
respiration, please offer help as soon as possible. Breathe/ Fall
in a At xxx site, a person falls in a faint. A nearby Coma faint
rescuer who can provide first aid, please offer help as soon as
possible.
[0097] Another possible application scenario is real-time
location-based traffic information pushing. A most common scenario
is that a traffic accident occurs on a road, which leads to a
traffic jam; however, a driver of a vehicle blocked on the road or
another driver who is about to drive into the road does not know a
reason and situation of the traffic jam, for example, normal car
crawling, complete blocking of the road, or that the traffic
accident has been handled.
[0098] In this scenario, the alarm terminal may be a terminal that
is authenticated, for example, a terminal exclusively used by the
traffic police, and registers with the first network device side,
where the first network device is, for example, an alarm center
server; or the alarm terminal may be a common terminal.
[0099] The alarm terminal sends the alarm information to the first
network device using, for example, a radio communications system.
In this case, the alarm information is, for example, road
information; and the alarm terminal may further send the location
information of the alarm terminal to the first network device. For
example, the road information sent by the alarm terminal is that
"two cars are rear-ended at xxx intersection, and it is estimated
that handling will be completed in five minutes". After receiving
the road information, the first network device first determines
whether the alarm terminal is a registered terminal or a real-name
terminal. If it is determined that the alarm terminal is a
registered terminal or a real-name terminal, the first network
device generates the first guide information, where the first guide
information is, for example, information including road guide
content. For example, the first guide information is that "a
traffic stream in x direction of xxx road is slow because two cars
are rear-ended, it will go back to normal in five minutes, and a
driver who needs to pass by this road can be at ease for driving".
The first network device may select the target terminal, that is,
select an object to which the first guide information is sent. For
example, the first network device may calculate, according to the
location information of the alarm terminal and the road
information, which road section or sections are affected, and
select a base station sector that is close to the road section to
send the first guide information to the corresponding target
terminal.
[0100] Further, if a user needs to receive information including
road guide content in real time, corresponding terminal road
software may be installed in a terminal used by the user, and
whether a function of receiving a road guide is enabled may be set;
and if the user sets that the function of receiving a road guide is
enabled for the terminal, the first network device may send
information including road guide content to the terminal.
Correspondingly, the first network device may also send information
including road guide content only to a terminal in which the
terminal road software is installed, so as not to disturb another
user who does not drive on this road section or a user who does not
need to receive information including road guide content.
[0101] Preferably, the first guide information may further include
the location information of the alarm terminal and/or navigation
information, where the navigation information is navigation
information between the target terminal and the alarm terminal.
Different target terminals correspond to different navigation
information.
[0102] Preferably, in this embodiment of the present disclosure,
that the first network device generates the first guide information
according to the alarm information and sends the first guide
information to a target terminal may include that the first network
device generates the first guide information according to the alarm
information; the first network device determines the target
terminal according to the first guide information, and sends the
first guide information to the target terminal, where the target
terminal is a terminal that is determined, by the first network
device according to the first guide information, among terminals
that are within same base-station signal coverage in which the
alarm terminal is located, or, a terminal that is determined, by
the first network device according to the first guide information,
among terminals whose distances from the alarm terminal are less
than the threshold.
[0103] That is, the first network device may determine the target
terminal according to the first guide information. For example, if
the meaning of the alarm information is that "a person falls into
water and is rescued, but is in a coma", the first network device
may expect to find a rescuer who is near the help seeker and can
perform artificial respiration. Therefore, the meaning of the first
guide information generated by the first network device may be that
"a person nearby falls into water and is rescued; and if you are
familiar with artificial respiration, please offer help at once". A
user of the target terminal selected by the first network device
should be familiar with artificial respiration, that is, the target
terminal is selected according to the first guide information.
[0104] Preferably, in this embodiment of the present disclosure,
that the first network device determines the target terminal
according to the first guide information includes that the first
network device determines, according to at least the first guide
information and forte information of users corresponding to
terminals that are within same base-station signal coverage in
which the alarm terminal is located, the target terminal among the
terminals that are within the same base-station signal coverage in
which the alarm terminal is located; or, the first network device
determines, according to at least the first guide information and
forte information of users corresponding to terminals whose
distances from the alarm terminal are less than the threshold, the
target terminal among the terminals whose distances from the alarm
terminal are less than the threshold.
[0105] Preferably, in this embodiment of the present disclosure,
the sending the first guide information to a target terminal
includes sending the first guide information to a second network
device, and sending, using the second network device, to the target
terminal second guide information that includes the first guide
information, where the target terminal is a terminal that is
determined, by the second network device according to location
information of the alarm terminal and the second guide information,
among terminals that are within same base-station signal coverage
in which the alarm terminal is located, or, a terminal that is
determined, by the second network device according to location
information of the alarm terminal and the second guide information,
among terminals whose distances from the alarm terminal are less
than the threshold.
[0106] That is, the first network device may send the first guide
information to the target terminal; or, the first network device
may send the first guide information to the second network device,
and the second network device may generate the second guide
information, include the first guide information in the second
guide information, and send the second guide information to the
target terminal.
[0107] For example, the second network device may be a network
device in a radio communications system, for example, a base
station; or, the second network device may be a social network
server or the like, which is not limited by the present disclosure.
The social network server in this embodiment of the present
disclosure includes but is not limited to a background server for a
social functioning website such as WeChat, microblog, or
Facebook.RTM. (a social service networking site).
[0108] If the first guide information needs to be sent to the
second network device, the first guide information may be guide
information including essential help-seeding content, for example,
the first guide information may be information including
help-seeding content or may be information including road guide
content; or the first guide information may include only the alarm
information or include only the information about the alarm
terminal, but does not include essential help-seeding content, that
is, the essential help-seeding content needs to be generated by the
second network device. In this case, the second network device
needs to analyze the alarm information. A specific analyzing
process is similar to the foregoing analyzing process of the first
network device, and for a specific example refer to Table 1,
described above.
[0109] For example, after receiving the first guide information
sent by the first network device, a network device in a radio
communications system sends the second guide information to a
determined target terminal according to the location information of
the alarm terminal. For example, the network device in the radio
communications system sends, according to a base station in which
the alarm terminal is located, the second guide information to
terminals within coverage of the base station; or the network
device in the radio communications system sends, according to a
location of the alarm terminal, the second guide information to
terminals whose distances from the alarm terminal are less than a
preset distance.
[0110] The second guide information may include, for example, the
location information of the alarm terminal and/or navigation
information. The navigation information is navigation information
between the target terminal and the alarm terminal. When target
terminals are different, corresponding navigation information is
also different.
[0111] Further, the second guide information sent by the second
network device may not include the location information of the
alarm terminal, and the target terminals that receive the second
guide information may feed an acknowledgement message back to the
second network device, where the acknowledgement message may be
used to indicate whether a user of a corresponding target terminal
can offer rescue. If the acknowledgement message fed back by a
target terminal is a message for confirming rescue, the second
network device may further send the location information of the
alarm terminal and/or navigation information to the target
terminal, to help the rescuer find the help seeker as soon as
possible; and if the acknowledgement message fed back by a target
terminal is a message for confirming no rescue, the second network
device does not need to send other messages to the target terminal,
which can reduce, to the greatest extent, an amount of information
that the second network device needs to send, and less information
that needs to be sent indicates a higher information sending speed,
thereby saving time.
[0112] For example, a target terminal that receives the second
guide information may feed back to the network device in the radio
communications system whether a user using the target terminal can
perform rescue. For example, if obtaining a message for confirming
rescue from a target terminal, the network device in the radio
communications system may send the location information of the
alarm terminal and/or navigation information to the target
terminal, and instruct a user using the target terminal to find the
help seeker quickly.
[0113] The social network server may collect/acquire geographical
location information of each online terminal, that is, the server
can grasp the geographical location information of each terminal in
real time. After receiving the alarm information, the social
network server may look up, according to the location information
of the alarm terminal, online terminals that are within a distance
from the alarm terminal, and send the second guide information to
these terminals.
[0114] For example, the social network server may first send the
second guide information to target terminals that are within a
100-meter radius of the alarm terminal; if no terminal replies to
confirm rescue within a preset period of time, the social network
server may extend the range to a 200-meter radius of the alarm
terminal, and send the second guide information to target terminals
that are within the range, and so on; the social network server
sends the second guide information as much as possible until a
response of confirming rescue is received.
[0115] Further, when each terminal registers with the social
network server, a corresponding user may note a rescue forte of the
user, for example, a swimming lifeguard, a surgeon, wrestling, and
artificial respiration. In addition, the corresponding user may set
in real time whether a "rescue" function is enabled for social
terminal software corresponding to the social network server; and
when the user disables the rescue function, the server does not
push the second guide information to the user.
[0116] All kinds of terminal software mentioned in the present
disclosure may be, for example, all kinds of communications
software such as WeChat, QQ (a kind of instant messaging software),
and Skype.RTM. (a kind of communications software).
[0117] Preferably, after receiving the first guide information, the
social network server may perform screening, according to the
location information of the alarm terminal, to obtain a terminal
that meets a condition and for which the rescue function is
enabled; and further, the social network server obtains, by
matching according to the second guide information, a user that
meets a rescue condition, that is, obtaining, by matching, a user
that can offer rescue; that is, the social network server selects a
corresponding target terminal according to the location information
of the alarm terminal and the second guide information, and then
pushes the second guide information to the selected target
terminal.
[0118] For example, the second guide information generated by the
social network server is that "at xxx site, a person falls into
water and is rescued; and a nearby rescuer who can perform
artificial respiration, please offer help as soon as possible". The
social network server first selects, from users near the alarm
terminal, an online user that enables the rescue function; and then
obtains a rescue forte by matching according to the second guide
information, where the rescue forte in this case includes "swimming
lifeguard" and "artificial respiration". The social network server
pushes the second guide information to the two types of users; and
for other users, although distances from the alarm terminal are
relatively short, and the rescue function is enabled, because the
users do not have the corresponding rescue forte, the social
network server may not push the second guide information to the
users. And the social network server may record a historical rescue
record of a registered user, and mark and rank the registered user;
and when selecting a nearby user, the server may prefer a user who
has a greater rescue score or a higher rank.
[0119] Optionally, when a rescuer confirms offering help, the
rescuer may click for confirming after receiving the second guide
information, that is, replying to confirm rescue to the social
network server; the social network server may further send the
location information of the alarm terminal or navigation
information to a terminal of the rescuer, or may send the location
information and the navigation information at the same time; and
the social network server may also send information about the
rescuer to the alarm terminal. Alternatively, the social network
server may send to the alarm terminal information about all
rescuers who are obtained by screening, a user of the alarm
terminal may select at least one rescuer from the rescuers and feed
the at least one rescuer back to the social network server. After
the rescuer confirms rescue or the user of the alarm terminal
selects a rescuer, the social network server may send the location
information of the alarm terminal or navigation information to the
terminal of the rescuer, or may send the location information and
the navigation information at the same time. The navigation
information is a path along which the rescuer can find the help
seeker, and a starting point and an ending point are a location of
the rescuer and a location of the help seeker respectively. It can
be seen that, for different target terminals, navigation
information sent by the social network server may be different.
[0120] Preferably, in this embodiment of the present disclosure,
that the first network device generates first guide information
according to the alarm information, and sends the first guide
information to a target terminal includes that the first network
device requests, according to the information about the alarm
terminal that is carried in the alarm information, location
information of the alarm terminal from a second network device; the
first network device receives the location information of the alarm
terminal that is fed back by the second network device; the first
network device generates the first guide information according to
the alarm information and the location information of the alarm
terminal, where the location information of the alarm terminal is
obtained by the second network device by means of AGPS, or the
location information of the alarm terminal is obtained by the
second network device in a TOA manner; and the first network device
sends the first guide information to the second network device, and
sends, using the second network device, to the target terminal
second guide information that includes the first guide
information.
[0121] If the alarm terminal does not send the location information
of the alarm terminal to the first network device, the first
network device needs to obtain the location information of the
alarm terminal. The information about the alarm terminal may be,
for example, an identifier of the alarm terminal; and the first
network device may request to obtain the location information of
the alarm terminal from the second network device according to the
identifier of the alarm terminal.
[0122] For example, if the alarm terminal does not include the
positioning module, obviously the alarm terminal cannot report the
location information of the alarm terminal. The first network
device may request to obtain the location information of the alarm
terminal from the network device in the radio communications
system.
[0123] Preferably, in this embodiment of the present disclosure, if
the second network device needs to determine the location
information of the alarm terminal, the second network device can
only be a network device in the radio communications system, and
cannot be a social network server.
[0124] After the first network device receives the alarm
information but does not receive the location information of the
alarm terminal, the first network device sends, to the network
device in the radio communications system, a request for acquiring
the location information of the alarm terminal, and the first
network device may send the information about the alarm terminal to
the network device in the radio communications system. The network
device in the radio communications system calculates the location
information of the alarm terminal according to the information
about the alarm terminal, and sends the location information to a
server of a 110 alarm center.
[0125] A possible manner of the first network device requesting to
obtain the location information of the alarm terminal from the
network device in the radio communications system is that a Visitor
Location Register (VLR) in the radio communications system is used
to calculate the location information of the help-seeking user, and
the VLR identifies, according to a name of a base station to which
the alarm terminal belongs, a physical location of the base
station, and determines that the physical location of the base
station is the location of the alarm terminal.
[0126] A possible manner of the first network device requesting to
obtain the location information of the alarm terminal from the
network device in the radio communications system is confirming a
location of the mobile terminal using TOA. TOA and time difference
of arrival (TDOA) are positioning methods based on radio-wave
transmission time, and are also positioning methods of three base
stations; positioning of both TOA and TDOA requires three base
stations whose locations are known to cooperate at the same time;
the three base stations calculate distances from the alarm
terminal, and finally calculate an actual physical location of the
alarm terminal. This manner is more accurate than the foregoing
manner, and is completed by a base station in the radio
communications system.
[0127] In a more specific scenario, a elder citizen carries a
terminal or a wearable device; when the senior citizen is in danger
(for example, tumbling or a sudden disease attack), the elder user
may trigger the terminal or the wearable device to generate a
help-seeking signal and send the help-seeking signal to an alarm
center (the first network device). Alarm content may be selected
from, for example: 1. a danger occurs, and help is needed; 2. a
fault of another person causes danger, and help is needed; and the
like. A danger type may be further included; and with improvement
of the terminal or the wearable device, a physical sign parameter
of the elder user may be further sent. The alarm center server
generates a rescue guide according to the foregoing obtained
help-seeking signal, and sends the rescue guide to a person near
the elder user who seeks help. The foregoing method may be used in
this scenario; in addition, a manner in which the user of the
terminal or the wearable device sends the alarm information may
further be that the alarm center (the first network device)
receives alarm information sent by an alarm terminal; and after
confirming the alarm information, the alarm center generates first
help-seeking information (which may be called first guide
information) according to the alarm information, and sends the
first help-seeking information to a target terminal, so that the
target terminal can respond to the alarm information according to
the first help-seeking information, where the target terminal is a
terminal selected from terminals that are within same base-station
signal coverage in which the alarm terminal is located, or the
target terminal is a terminal selected from terminals whose
distances from the alarm terminal are less than a threshold.
Further, the target terminal may be a specified terminal, for
example, a terminal user with a set pre-stored number, or an
associated user (a child, relative, doctor, or the like).
[0128] In this scenario, according to alarm or help-seeking
information, a purposeful and timely response is more easily
obtained, and misgivings of people about a help-seeking request are
easily dispelled.
[0129] Referring to FIG. 2, an embodiment of the present disclosure
provides another information sending method, and a main procedure
of the method is as follows.
[0130] Step 201: A first network device receives alarm information
sent by an alarm terminal.
[0131] Step 202: After confirming the alarm information, the first
network device generates first guide information according to the
alarm information, sends the first guide information to a second
network device, and sends, using the second network device, to a
target terminal second guide information that relates to the first
guide information, where the target terminal is a terminal that is
determined, by the second network device according to location
information of the alarm terminal and the second guide information,
among terminals that are within same base-station signal coverage
in which the alarm terminal is located, or, a terminal that is
determined, by the second network device according to location
information of the alarm terminal and the second guide information,
among terminals whose distances from the alarm terminal are less
than a threshold.
[0132] The manner in which the first network device confirms the
alarm information or puts the alarm information on a record has
been described in the procedure in FIG. 1, which is not described
herein again.
[0133] Preferably, in this embodiment of the present disclosure,
the second guide information is information generated by the first
network device according to the first guide information, or the
second guide information is the first guide information.
[0134] Preferably, in this embodiment of the present disclosure,
that the second network device sends to the target terminal second
guide information that relates to the first guide information may
include that the second network device determines the second guide
information according to the first guide information; and the
second network device determines the target terminal according to
the second guide information and the location information of the
alarm terminal, and sends the second guide information to the
target terminal.
[0135] That is, the second network device may determine the target
terminal, according to the second guide information and the
location information of the alarm terminal, among terminals that
are within same base-station signal coverage in which the alarm
terminal is located, or, the second network device may determine
the target terminal, according to the second guide information and
the location information of the alarm terminal, among terminals
whose distances from the alarm terminal are less than the
threshold. For example, if a meaning of the alarm information is
that "a person falls into water and is rescued, but is in a coma",
the second network device may expect to find a rescuer who is near
the help seeker and can perform artificial respiration. Therefore,
a meaning of the second guide information generated by the second
network device may be that "a person nearby falls into water and is
rescued; and if you are familiar with artificial respiration,
please offer help at once". When the second network device performs
selecting, a user of the selected target terminal should be
familiar with artificial respiration, that is, selecting according
to the second guide information.
[0136] Preferably, in this embodiment of the present disclosure,
that the second network device determines the target terminal
according to the second guide information includes that the second
network device determines, according to at least the second guide
information and forte information of users corresponding to
terminals that are within same base-station signal coverage in
which the alarm terminal is located, the target terminal among the
terminals that are within the same base-station signal coverage in
which the alarm terminal is located; or, the second network device
determines, according to at least the second guide information and
forte information of users corresponding to terminals whose
distances from the alarm terminal are less than the threshold, the
target terminal among the terminals whose distances from the alarm
terminal are less than the threshold.
[0137] Referring to FIG. 3, an embodiment of the present disclosure
provides an information sending method, and a main procedure of the
method is as follows.
[0138] Step 301: A terminal sends alarm information to a first
network device.
[0139] In this embodiment of the present disclosure, the terminal
may be the alarm terminal described above. For example, a user
triggers the help-seeking module of the alarm terminal, and the
alarm terminal sends the alarm information to the first network
device.
[0140] Step 302: The terminal receives second guide information fed
back by the first network device, where the second guide
information is generated by the first network device according to
the alarm information.
[0141] Step 303: The terminal establishes a communications link
with a target terminal according to the second guide
information.
[0142] Preferably, the communications link may refer to a D2D
communications link. The second guide information may include
time-frequency resource information that is required by the
terminal during establishment of the D2D communications link.
[0143] Preferably, that the terminal establishes a communications
link with a target terminal according to the second guide
information includes that the terminal establishes a D2D
communications link with the target terminal according to the
second guide information.
[0144] Step 304: The terminal sends first guide information to the
target terminal over the communications link with the target
terminal, where the first guide information is generated by the
terminal according to the alarm information, and the target
terminal is a terminal selected from terminals that are within same
base-station signal coverage in which the alarm terminal is
located, or the target terminal is a terminal selected from
terminals whose distances from the alarm terminal are less than a
threshold.
[0145] Preferably, the terminal may generate the first guide
information according to the alarm information. For example, the
first guide information may be the alarm information; or the first
guide information may be information that has a guide function and
is generated by the terminal according to the alarm information,
for example, may be guide information described in the foregoing
embodiments.
[0146] Preferably, that the terminal sends first guide information
to the target terminal over the communications link with the target
terminal may include that the terminal sends the first guide
information to the target terminal over the D2D communications link
with the target terminal.
[0147] That is, the alarm terminal may directly communicate with
the target terminal, without transferring by another network
device, thereby improving communication efficiency. The terminals
communicate using a D2D standard. D2D is a technology that allows,
under control of a system, terminals to communicate directly by
reusing a cell resource, and D2D can improve spectrum efficiency of
a cellular communications system, reduce transmit power of a
terminal, and resolve to some extent a problem that spectrum
resources of a radio communications system are insufficient.
Resources occupied by each D2D communications link are equal to
those occupied by one cellular communications link. During D2D
communication, frequency resources and transmit power that are
required during communication are obtained under control of a
cellular base station. Cell users may communicate using a
base-station service, or may communicate directly over a D2D link.
A cellular communication base station communicates with a terminal
using a control signal, and terminals may perform service
communication directly.

[0185] The information sending method in the embodiments of the
present disclosure may include receiving, by a first network
device, alarm information sent by an alarm terminal; and after
confirming the alarm information, generating, by the first network
device, first guide information according to the alarm information,
and sending the first guide information to a target terminal, so
that the target terminal can respond to the alarm information
according to the first guide information, where the target terminal
is a terminal selected from terminals that are within same
base-station signal coverage in which the alarm terminal is
located, or the target terminal is a terminal selected from
terminals whose distances from the alarm terminal are less than a
threshold.
[0186] In the embodiments of the present disclosure, after
receiving the alarm information, the first network device may
generate the first guide information and send the first guide
information to the target terminal. In this way, the target
terminal may respond to the alarm information, and help rescue a
user of the alarm terminal. Because the target terminal is a
terminal selected from terminals that are within same base-station
signal coverage in which the alarm terminal is located, or the
target terminal is a terminal selected from terminals whose
distances from the alarm terminal are less than a threshold, which
means that a distance between the target terminal and the alarm
terminal is relatively short, so that the target terminal can
arrive at the site in time to rescue the user of the alarm
terminal, thereby effectively improving rescue efficiency. The
first network device automatically sends the first guide
information to the target terminal, where there may be one or more
target terminals, and the alarm terminal does not need to send the
first guide information one by one; therefore, efficiency of
information transmission is relatively high, and it is ensured to
the greatest extent that the user of the alarm terminal can be
rescued in time.
[0187] It may be clearly understood by a person skilled in the art
that, for the purpose of convenient and brief description, division
of the foregoing function units is taken as an example for
illustration. In actual application, the foregoing functions can be
allocated to different function units and implemented according to
a requirement, that is, an inner structure of an apparatus is
divided into different function units to implement all or part of
the functions described above. For a detailed working process of
the foregoing system, apparatus, and unit, refer to a corresponding
process in the foregoing method embodiments, and details are not
described herein again.
[0188] In the several embodiments provided in the present
application, it should be understood that the disclosed system,
apparatus, and method may be implemented in other manners. For
example, the described apparatus embodiment is merely exemplary.
For example, the unit division is merely logical function division
and may be other division in actual implementation. For example, a
plurality of units or components may be combined or integrated into
another system, or some features may be ignored or not performed.
In addition, the displayed or discussed mutual couplings or direct
couplings or communication connections may be implemented through
some interfaces. The indirect couplings or communication
connections between the apparatuses or units may be implemented in
electronic, mechanical, or other forms.
[0189] The units described as separate parts may or may not be
physically separate, and parts displayed as units may or may not be
physical units, may be located in one position, or may be
distributed on a plurality of network units. Some or all of the
units may be selected according to actual needs to achieve the
objectives of the solutions of the embodiments.
[0190] In addition, functional units in the embodiments of the
present application may be integrated into one processing unit, or
each of the units may exist alone physically, or two or more units
are integrated into one unit. The integrated unit may be
implemented in a form of hardware, or may be implemented in a form
of a software functional unit.
[0191] When the integrated unit is implemented in the form of a
software functional unit and sold or used as an independent
product, the integrated unit may be stored in a computer-readable
storage medium. Based on such an understanding, the technical
solutions of the present application essentially, or the part
contributing to the prior art, or all or some of the technical
solutions may be implemented in the form of a software product. The
software product is stored in a storage medium and includes several
instructions for instructing a computer device (which may be a
personal computer, a server, or a network device) or a processor to
perform all or some of the steps of the methods described in the
embodiments of the present application. The foregoing storage
medium includes any medium that can store program code, such as a
universal serial bus (USB) flash drive, a removable hard disk, a
read-only memory (ROM), a random access memory (RAM), a magnetic
disk, or an optical disc.
[0192] In the foregoing descriptions, the foregoing embodiments are
merely intended for describing the technical solutions of this
application in detail; however, the descriptions of the foregoing
embodiments are merely intended to help understand the method and
idea of the present disclosure, and shall not be construed as a
limitation on the present disclosure. Any variation or replacement
readily figured out by a person skilled in the art within the
technical scope disclosed in the present disclosure shall fall
within the protection scope of the present disclosure.
