Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to portable telephone
terminals and, more particularly, to a portable telephone terminal
having an answering function for switching between answer messages
in accordance with a caller number and the time, and also to a
terminal operable by a remote telephone set using caller number
authentication.
2. Description of the Related Art
Japanese Laid-Open Patent Application No. 10-66145 discloses a
mobile communication terminal having an answering function for
switching between answer messages depending on a caller number. A
call signal incoming at a called terminal from a calling terminal
includes a caller number and control information for controlling
the called terminal. The called terminal controls an answering mode
and switches between answer messages based on the caller number and
the control information. Answer messages for individual expected
callers are registered in the called terminal and retrieved
according to the flowchart of FIG. 7. Each answer message has
associated therewith a message identification number.
Referring to FIG. 7, when it is determined in step ST1001 that
there is an incoming call, a determination is made in step ST1002
as to whether the automatic answering mode is activated. When the
answering mode is activated, a determination is made in step ST1003
as to whether a calling number is identified. If the calling number
is identified, a determination is then made in step ST1005 as to
whether the calling number is registered in a directory. If the
calling number is registered, a determination is made in step
ST1006 as to whether the forced answering mode is on. If it is
determined that the forced answering mode is turned on, a
determination is made in step ST1007 as to whether a predetermined
answer message is to be used to automatically respond to the
particular caller. If an affirmative answer is yielded in step
ST1007, the answer message for that caller is used for response in
step ST1008. If a negative answer is yielded in steps ST1003,
ST1005, ST1006 and ST1007, a default answer message is used for
response to that caller in step ST1004.
If it is determined in step ST1002 that the answering mode is not
activated, similar steps (ST1011, ST1012 and ST1009) are executed.
When it is determined in step ST1009 that the forced answering mode
is not turned on, a normal voice call proceeds in step ST1010.
Japanese Laid-Open Patent Application No. 10-126495 and Japanese
Laid-Open Patent Application No. 9-182158 disclose a portable
telephone set provided with a capability whereby the portable
telephone set, if lost, can be remotely operated by another
telephone set so that a dialing operation using the lost portable
telephone set is prohibited. Japanese Laid-Open Patent Application
No. 10-126495 also discloses a portable telephone set configurable,
if lost, for a fixed call destination by feeding a remote operation
signal to the lost portable telephone set. Operations related to
the memory are prohibited so that the leak of personal information
and the illegal use of the portable telephone set are prevented.
Japanese Laid-Open Patent Application No. 9-182158 discloses a
system wherein a lock preventing an illegal use of a lost portable
telephone set is registered in a base station using another
telephone set so that call origination by an illegal user is
prevented.
A rapidly increasing number of portable telephone sets is being
used because of the convenience it provides in enabling
communication not bounded by time and place constraints. When a
user is not able to answer a call, the answering function is
utilized. The related-art mobile communication terminal disclosed
in Japanese Laid-Open Patent Application No. 10-66145 is provided
with an answering function for switching between answer messages
depending on the caller number. However, related-art mobile
communication terminals are not capable of switching between answer
messages for a particular caller in accordance with the time that a
call is received.
A user of a portable telephone set may want to answer a call from a
particular caller but does not want to answer a call from the
others. The answering function that meets such a requirement should
be provided with a forced alert function for alerting a user of a
call from a registered caller even when the answering mode is
activated.
Another problem with the portable telephone system according to the
related art is that an input of a password is required when a user
calls a lost portable telephone set and remotely sets up a locked
dialing option in the lost telephone set. When the user has
forgotten the password, the locked dialing option cannot be set up
when necessary.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a
portable telephone set in which the aforementioned problems are
eliminated.
Another and more specific object of the present invention is to
provide a mobile communication terminal such as a portable
telephone set provided with an answering function that enables
switching between answer messages in accordance with the time of
calling.
Still another object of the present invention is to provide a
portable telephone set in which a remote operation not requiring an
input of a password is enabled by specifying terminal numbers
(caller numbers) authorized to perform a remote operation for a
locked dialing option or a voice mail option.
The aforementioned objects can be achieved by a mobile
communication terminal comprising: timer means for detecting the
time when a call incoming signal including a caller number is
received from an originating terminal; caller number storage means
for storing control codes in relation to expected caller numbers,
the control codes being used to switch between different modes of
operation of the mobile communication terminal; answer message
storage means for storing messages to be returned to a caller; and
answer message selecting means referring to said caller number
storage means so as to determine whether the caller number included
in the incoming call signal is registered in said caller number
storage means, reading from said caller number storage means the
control code associated with the caller number, and selecting an
answer message stored in said answer message storage means based on
the caller number, the control code and the time of call detected
by said timer means.
The caller number storage means may store caller numbers, caller
names corresponding to the caller numbers and time-dependent
switching codes in relation to each other, the time-dependent
control codes designating callers for whom answer messages are
switched depending on a time zone in which the call is made.
The caller number storage means may store caller numbers, caller
names corresponding to the caller numbers and forced alert codes in
relation to each other, the forced alert code designating callers
triggering a forced alert option for alerting a user of the mobile
communication terminal of an incoming call even when an answering
mode is activated.
The caller number storage means may store caller numbers, caller
names corresponding to the caller numbers and locked dialing codes
in relation to each other, the locked dialing codes designating
callers authorized to set up a locked dialing option in the mobile
communication terminal from a calling terminal.
The caller number storage means may store caller numbers, caller
names corresponding to the caller numbers and voice mail codes in
relation to each other, the voice mail codes designating callers
authorized to set up a voice mail option in the mobile
communication terminal from a calling terminal.
According to the invention, mobile communication terminal is
provided with an answering function capable of selecting an answer
message in accordance with the caller number included in an
incoming call signal and switching between answer messages
depending on the time of call. Since it is possible to prepare a
variety of answer messages suitable for individual expected
callers, the answering function is enhanced.
The mobile communication terminal according to the invention is
provided with the capability of alerting the user if a call is
received from a designated caller even when the answering mode is
activated, by recognizing the caller prior to an off-hook operation
based on the caller number included in the incoming call signal.
Therefore, it is possible to distinguish between callers requiring
an answer and callers not requiring an answer.
In further accordance with the invention, when the caller number
matches the registered number assigned a remote operation code, the
caller is authorized to perform a remote operation such as setting
up of a locked dialing option or a voice mail option. With this, it
is possible to perform a remote operation without a password by
calling from a registered terminal.

the terminal responds to call incoming (ST304). The terminal refers
to the caller number registration table shown in FIG. 4 (ST305). If
it is determined that the caller ID retrieved from the call setting
message is registered in the caller number registration table
(ST306), a determination is made as to whether the forced alert is
set (ST307). If the forced alert is set, a call can proceed
(ST308). When the call is terminated (ST309), the mobile
communication terminal is returned to a wait state (ST310).
If it is determined that the caller ID retrieved from the call
setting message is not registered in the caller number registration
table (ST306), a preset message is sent to the network (ST317).
When the preset message has been sent, the caller is allowed to
leave a message (ST314). Control is then turned to step ST309.
If the originating ID is registered in the caller number
registration table but the forced alert is not set, a message to be
sent to the caller is selected in steps subsequent to ST311
depending on the time of call and the identity of the caller. In
step ST311, the caller number registration table is examined so as
to determine if time-dependent switching is set up for the caller.
If it is determined that time-dependent switching is set up for the
caller, the time of call is detected by a timer circuit included in
the time monitor Unit shown in FIG. 1 (ST312). If the time of call
from the caller is included in a first time zone, an answer message
designated for the caller and the first time zone is selected
(ST313). Subsequently, the caller can record a message (ST314).
If it is not determined that the time of call from the caller is
not included in the first time zone, an answer message designated
for the caller and a second time zone is selected (ST315).
Subsequently, a message from the caller is recorded (ST314). If the
call is from a caller for which time-dependent switching is not set
up, a predetermined message designated for the caller is selected
and sent to the network (ST316). Subsequently, a message from the
caller is recorded (ST314). Control is then turned to step
ST309.
As has been described, the mobile communication terminal according
to the first embodiment is provided with the capability of
selecting an answer message depending on the caller and the forced
alert capability for alerting the user of the terminal when there
is a call from a designated caller. Further, the answer message
selecting capability is controlled in accordance with the time.
Accordingly, the user of the terminal can properly set up the
terminal for expected callers.
Embodiment 2
FIG. 5 is a flowchart showing how a remote operation function of a
mobile communication terminal is controlled according to the second
embodiment. It is assumed that a portable telephone set
(hereinafter, simply referred to as a terminal) is in a wait state
(ST501). When a call arrives at the terminal (ST502), a
determination is made as to whether the caller ID retrieved from
the call setting message is registered in the caller number
registration table and whether the caller is authorized to perform
a remote operation (ST503). If it is determined that the caller is
registered and authorized to perform a remote operation, after a
predetermined period of time elapses (ST504), the terminal responds
to the call (ST505).
When the caller inputs a number for setting up the locked dialing
option (ST506), the terminal verifies the input number (ST507). If
the input number is verified, the locked dialing option is set up
(ST508). When the locked dialing option has been set up, the call
is terminated (ST509), whereupon the terminal is placed in a wait
state. When the number input for the locked dialing option is not
verified, the number of times that the verification fails is
counted (ST511). When the number of times exceeds a predetermined
count, control is returned to step ST506.
As has been described, the mobile communication terminal according
to the second embodiment does not require an input of a password.
Therefore, the user can set up a locked dialing option whenever
necessary. By configuring the telephone set at home as the only
authorized terminal, it is possible to prevent strangers from
setting up the locked dialing option.
Embodiment 3
FIG. 6 is a flowchart for controlling the voice mail function of a
mobile communication terminal according to the third embodiment. It
is assumed that a portable telephone set (hereinafter, simply
referred to as a terminal) is in a wait state in step ST601. When a
call arrives at the terminal (ST602), a determination is made as to
whether the caller ID retrieved from the call setting message is
registered in the caller number registration table and whether the
caller is authorized to perform a remote operation (ST603). If it
is determined that the caller is registered and authorized to
perform a remote operation, after a predetermined period of time
elapses (ST604), the terminal responds to the call (ST605).
When the caller inputs a number for setting up a voice mail option
(ST606), the input number is verified (ST607). If the input number
is verified, the voice mail option is set up (ST608). When the
voice mail option has been set up, the call is terminated (ST609)
so that the terminal is placed in a wait state (ST610). If the
input number is not verified, the number of times that the
verification fails is counted (ST611). If the number of times
exceeds a predetermined count (ST612), control is turned to step
ST606.
As has been described, the mobile communication terminal according
to the third embodiment does not require an input of a password to
set up a voice mail option remotely. Thus, even when the user has
forgot the password, the user can still set up a voice mail
option.
The present invention is not limited to the above-described
embodiments and variations and modifications may be made without
departing from the scope of the present invention.
