DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2
FIG. 2 is a block diagram of a communication device according to the first embodiment of the present invention and a flowchart showing processing thereof. In FIG. 1, a mobile terminal (referred to as “terminal 1” in FIG. 1), which is a desired mobile terminal such as a mobile phone or a PHS, is usually connected wirelessly to a base station 4 and connected to the base station 4. The connected exchange 5 establishes connection with the other party in the same manner as in the case of a wired telephone.

The exchange 5 has a subscriber data management device (HLR: Home Location Regist) for managing subscriber data.
er) 6 are connected. This subscriber data management device 6
Manages various data of the subscriber, changes and sets data in response to a signal input from the exchange 5, and performs various operations in accordance with the change of data. As one of such functions, a process of setting a call stop of the portable terminal 1 and a process of canceling the call stop as described later are performed. The exchange 5 and the subscriber data management device 6 constitute a means for preventing unauthorized use.

A number of portable terminals (not shown) such as the portable terminal 1 are connected to the exchange 5 via the base station 4 and the second terminal 2 via a wired line (or a wireless line). Are connected. The second terminal 2, which is a terminal other than the desired portable terminal, is a general terminal such as a home telephone, a public terminal such as a public telephone, or a terminal such as a portable terminal such as a PHS or a portable telephone. However, in order to set the call suspension of the mobile terminal 1 and release the call suspension as described later, the terminal needs to be a terminal capable of setting the destination sub-address.

Next, in the above configuration, a process for setting a call stop of the portable terminal 1 and a process for releasing the call stop will be described with reference to FIG. First, the user of the mobile terminal 1 dials a predetermined number (special number) predetermined by a communication carrier subscribing to the mobile terminal 1 from the second terminal 2 for which a destination subaddress can be set. The special number is a number for requesting the setting of a call state, specifically, a number simply indicating a request for setting of a call state, or a first number indicating a setting of a call stop or a call stop. Can be selected variously according to the specification, for example, when the second number is a request for canceling the request. The example shown in FIG. 2 is an example using a number simply indicating a request for setting a call state.

When dialing from the second terminal 2 a special number predetermined by a communication carrier subscribing to the mobile terminal 1, at least the number of the mobile terminal 1 is specified in the destination subaddress of the special number to be dialed. Set a password and dial. On the other hand, on the exchange 5 side, upon detecting the incoming call by the above-mentioned dial (see step 100 in FIG. 2), it is determined whether or not the incoming call is a request for setting the call suspension or canceling the call suspension. (See step 102 in FIG. 2). This determination is made based on whether or not the special number has been dialed. If it is determined that the special number has been dialed, it is determined that the request is a call stop setting or call release cancellation request, and the mobile terminal 1 And the password are separately separated and sent to the subscriber data management device 6 (see step 104 in FIG. 2). Also,
If it is determined that it is not a special number dialing, it is determined that it is not a request to set call suspension or cancel call suspension,
This series of processes is completed (NO in step 102 of FIG. 2).

Next, in the subscriber data management device 6, the number of the portable terminal 1 and the password inputted from the exchange 5 are stored in the storage means of the subscriber data management device 6 constituted by, for example, a non-volatile memory (FIG. (Not shown) is collated with the data (the number of the portable terminal 1 and the personal identification number) stored therein (see step 106 in FIG. 2). When it is determined that they match, the subscriber data management device 6 sets a call stop or rewrites predetermined data for canceling the call stop, and sets a call stop or cancels the call stop. (See step 108 in FIG. 2).

In other words, in this case, when dialing from the second terminal 2, the special number is merely a number for requesting the setting of the call state, and is for requesting the setting of the call stop or canceling the call stop. Is not specified, the number of the mobile terminal 1 and the personal identification number are input to the subscriber data management device 6 as described above, and each time it is determined that the data matches the data stored in advance. Each time, the mobile terminal 1 is set to a state opposite to the latest state of the call state (in other words, the state of the latest circuit switching).
For example, in the state where the call suspension is released, if it is determined that the data match in the data comparison in step 106 of FIG. 2, the call suspension is set by the subscriber data management device 6. Conversely, if the state immediately before the data is determined to match in step 106 is the state in which the call is suspended, step 108
Then, the suspension of the call suspension is released.

The special numbers may include two numbers, a first number for requesting a call suspension setting and a second number for requesting cancellation of the call suspension. In this case, in step 108, the result of the determination of the meaning of the special number in step 102, that is, whether the special number is a number for requesting a call suspension or a number for requesting cancellation of the call suspension is determined. Based on the special number, if the special number is a first number requesting a call stop, the call state of the mobile terminal 1 is set to a call stop state,
If the special number is a second number requesting the release of the call suspension, the portable terminal 1 is released from the call suspension and is set to a state in which a call can be made. In this case, if a special number requesting call suspension is received while call suspension is set,
Since the call is already stopped, no change occurs in the call state. Also, if a special number requesting cancellation of call suspension is entered while call suspension has been released,
Since the call suspension has already been released, no change occurs in the call state.

When dialing the second terminal 2 by setting the number of the mobile terminal 1 and the personal identification number in the destination subaddress in addition to the special number and dialing, a predetermined setting for discriminating between setting and canceling the call suspension is provided. May be set as the destination sub-address and dialing may be performed. For example, it is also possible to set the number for setting the call suspension to "1" and the number for canceling the call suspension to "0", and to set this after the password of the destination sub-address, for example. it can. Then, in this case, in step 108 of FIG. 2, a number for setting the call suspension and canceling the call suspension is determined. If "1", the call suspension setting is "0". , The setting for canceling the call suspension is performed.

As described above, the communication device of the present embodiment is a communication device for switching a plurality of terminals via a plurality of communication lines. An unauthorized use preventing means (exchange 5 and subscriber data management device 6) for canceling the suspension is provided, and the unauthorized use preventing means requests the terminal 2 other than the desired portable terminal 1 to set a call state. (The number set as the special number or the destination sub-address), the number of the desired mobile terminal 1 and the password are received, and the number of the desired mobile terminal 1 and the password in the storage unit match the data set in advance. When it is determined, based on the predetermined number, a call stop process or a call stop release process for the desired portable terminal 1 is performed according to the meaning of the predetermined number. There.

[0025] The unauthorized use prevention means includes a storage means (not shown) in which the predetermined number (number set in the special number or destination sub-address), the number of the portable terminal and the personal identification number are set.
And the special number from the terminal 2 other than the desired portable terminal 1,
Receiving means (not shown) for receiving the number and password of the desired portable terminal 1; and data in which the number and password of the desired portable terminal 1 received by the receiving means are preset in the storage means. (No. of mobile terminal 1 and personal identification number)
If it is determined that they match, the subscriber data management device 6 performs the call stop processing or the call stop release processing of the desired portable terminal 1 based on the predetermined number according to the meaning of the predetermined number. And

In the case where the predetermined number is not a number indicating a call stop or a release of the call stop but a number simply indicating a call state setting, the subscriber data management device 6
When it is determined that the number and the password of the desired portable terminal 1 match the data set in the storage means in advance, the state of the line exchange with respect to the portable terminal is determined based on the predetermined number. Is set to a call stop state opposite to the most recent state or to a call stop release state. Further, when the special number is a first number for requesting a call suspension or a second number for requesting cancellation of the call suspension, the subscriber data management device 6 determines that the desired mobile terminal 1 has a desired number and a password. When it is determined that the special number matches the data (the number of the mobile terminal 1 and the password) preset in the storage means, it is determined whether the special number is a number for requesting the setting of the call suspension or the release of the call suspension. Then, a call stop process or a call stop release process indicated by the predetermined number is performed.

Further, the unauthorized use prevention means comprises an exchange 5 and a subscriber data management device 6, wherein the predetermined number (the number set in the special number or destination subaddress) is:
It is not a number that means call suspension or cancellation of call suspension,
In the case of a number simply indicating the setting of a call state, the exchange 5 sets the mobile terminal 1 that desires to set or cancel the call stop.
When a predetermined number requesting the setting of the call state, the number of the desired portable terminal 1 and the password are received from the terminal 2 other than the terminal 2, the number and the password of the portable terminal 1 are transmitted to the subscriber data management device. 6 and the subscriber data management device 6 determines that the number and the password of the mobile terminal 1 input from the exchange 5 match the preset data, The state is set to a state opposite to the state of the latest call stop or the cancellation of the call stop.

The unauthorized use preventing means comprises an exchange 5 and a subscriber data management device 6, and the predetermined number (a number set as a special number or a destination subaddress) is a first requesting a call stop. The exchange 5 is a telephone number or a second number for requesting cancellation of the call suspension, and the exchange 5 sends the predetermined number and the desired mobile terminal Receiving the number and the password, and transmitting the number of the desired portable terminal, the password and the number for requesting the suspension of the call or the release of the suspension of the call to the subscriber data management device 6, wherein the subscriber data management device 6 If it is determined that the desired mobile terminal 1 number and password input from the exchange 5 match the preset data, the number for requesting the call stop or the release of the call stop. Le is determined whether the input is to perform the desired cancellation of the setting process or call stop call stop for the mobile terminal 1 treatment.

[0029] Therefore, it is possible to perform the setting of suspension of the call of the portable terminal and the release of the suspension of the conversation by a predetermined operation on the user side without going through the setting work of the communication carrier. In addition, it is possible to prevent a third party from easily setting the call suspension and releasing the call suspension. Furthermore, there is no time limit, and it is possible to quickly set the call suspension and release the call suspension.

FIGS. 3 and 4 are a block diagram of a communication device according to a second embodiment of the present invention and a flowchart showing the processing thereof. Note that the same components as those shown in FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted. In the second embodiment, a call termination is set or canceled by a predetermined operation from a third terminal 3 (in FIG. 3, denoted as "terminal 3") in which a destination subaddress cannot be set. is there.

First, the user of the portable terminal 1 which is a desired portable terminal is a third terminal which is a terminal other than the desired portable terminal.
The terminal 3 dials a predetermined number (special number) designating the setting of the call suspension and the release of the call suspension predetermined by the communication carrier subscribing to the mobile terminal 1. The special number is a number for requesting the setting of a call state, specifically, a number simply indicating a request for setting of a call state, or a number indicating a setting of a call stop or cancellation of a call stop. Various selections can be made depending on the specifications, such as when the number is required. The example shown in FIG. 4 is an example in which a number simply indicating a request for setting a call state is used.

On the other hand, the exchange 5 detects an incoming call by the above-mentioned dial (see step 200 in FIG. 4).
It is determined whether or not the incoming call is a number for which a call state setting is requested, that is, whether or not a call stop setting and a call stop release request are made (see step 202 in FIG. 4). That is, this determination is made based on whether or not the special number has been dialed. If it is determined that the special number has been dialed, it is determined that the request is a call state setting request, and the process of step 204 described below is executed. On the other hand, if it is determined that the special number has not been dialed, it is determined that it is not a request to set a call stop and cancel the call stop, and this series of processing ends.

On the other hand, if it is determined that the request is for a call state setting request, the exchange 5 sends a guidance message for prompting the third terminal 3 to input the number of the portable terminal 1 and a password. (See step 204 in FIG. 4), third
(Step 206 in FIG. 4). Here, in order to input data from the third terminal 3, the third terminal 3 has a so-called push button (not shown) for inputting numerical values and symbols. Is preferably performed by pressing. Then, in the exchange 5, after the message is transmitted, the data input from the third terminal 3 is separately separated into the number of the portable terminal 1 and the personal identification number and transmitted to the subscriber data management device 6. (See step 208 in FIG. 4).

In the subscriber data management device 6, the number of the portable terminal 1 and the password inputted from the exchange 5 are
For example, whether or not the data matches the data (the number of the mobile terminal 1 and the password) stored in the storage means (not shown) of the subscriber data management device 6 constituted by a nonvolatile memory is checked. (See step 210 in FIG. 4). When it is determined that they match, the call data is set by the subscriber data management device 6 and predetermined data for canceling the call suspension is rewritten to set the call state. Is performed (see step 212 in FIG. 4).

That is, in this case, the data input from the third terminal 3 is simply a special number for requesting the setting of the call state, the number of the portable terminal 1, and the personal identification number. Since the user does not input a predetermined number for distinguishing the release of the
Each time it is determined that the number and the password match,
A process for setting the communication state of the portable terminal 1 (in other words, the state of the most recent circuit switching) to the state opposite to the most recent state is performed. For example, if the state immediately before inputting the special number, the number of the mobile terminal 1 and the personal identification number from the third terminal 3 is assumed to be a state in which the call is suspended, in this case, The suspension of the call is released by the input of the data. On the other hand, if the state immediately before inputting the special number, the number of the portable terminal 1 and the personal identification number from the third terminal 3 is a state where the call suspension is released, in this case, from the third terminal 3 By the input of the data, the call stop setting is performed.

As the special number, two numbers may be used: a number requesting the setting of the call suspension and a number requesting the release of the call suspension. In this case, step 1
In step 08, the result of the determination of the meaning of the special number in step 202, that is, whether the special number is a number for requesting a call suspension or a number for requesting cancellation of a call suspension is determined. If the special number is a number for requesting a call stop, the call state of the mobile terminal 1 is set to the call stop state, and if the special number is a number for requesting the release of the call stop, the mobile terminal 1 The call suspension is canceled and the call is set to be ready. In this case, if a special number requesting a call stop is received in a state where the call is stopped, the call state is not changed because the call stop state has already been set. Also,
Even if a special number for requesting the release of the call suspension is input in a state where the call suspension has been released, no change occurs in the call state because the call suspension has already been released.

When the number of the portable terminal 1 and the personal identification number are inputted from the third terminal 3, a predetermined number for distinguishing the setting of the call suspension and the release of the suspension may be inputted at the same time. Good. For example, it is assumed that the number for setting the call suspension is “1”, the number for canceling the call suspension is “0”, and these are input together with the number of the mobile terminal 1 and the password. be able to. Then, in this case, in step 212 of FIG. 4, a number for setting the call suspension and releasing the call suspension is determined, and “1” is set.
Then, if the call suspension setting is “0”, the call suspension release setting is performed.

As described above, in the second embodiment, in a communication apparatus for switching a plurality of terminals via a plurality of communication lines, a communication stop for a desired portable terminal 1 among the plurality of terminals is performed. And a means for preventing unauthorized use (exchange 5 and subscriber data management device 6) for releasing the suspension of the call, wherein the means for preventing unauthorized use comprises the desired portable terminal 1
Receiving a predetermined number (special number) requesting the setting of the call state from a terminal other than the terminal, transmitting a guidance message requesting data input to the terminal 2 other than the desired portable terminal 1, and transmitting the message Thereafter, when the number and the password of the desired mobile terminal 1 are input from the terminal 2 other than the desired mobile terminal 1, the number and the password of the desired mobile terminal are stored in the storage means in advance. When it is determined that they coincide with each other, a call stop process or a call stop release process by the desired portable terminal is performed based on the predetermined number.

In the case where the predetermined number is not a number indicating a call stop or a release of the call stop but a number simply indicating setting of a call state, the unauthorized use preventing means may include:
If it is determined that the number and the password of the desired portable terminal 1 match the data set in the storage means in advance, the call of the desired portable terminal 1 is switched to the state opposite to the latest state. The setting processing to the stop state or the setting processing to the release state of the call suspension is performed. Further, the predetermined number is not a number simply indicating the setting of a call state, but a first number requesting a call suspension or a second number requesting a release of the call suspension, and the unauthorized use prevention means includes: When it is determined that the received number and password of the desired portable terminal 1 match the data set in the storage means in advance, the predetermined number is a number for requesting either the stop of the call or the release of the stop of the call. Then, a call stop process or a call stop release process corresponding to the meaning of the predetermined number is performed.

Further, the means for preventing unauthorized use includes an exchange 5 and a subscriber data management device 6, and the exchange 5 is a terminal 2 other than the portable terminal 1 which wants to stop the call or cancel the call stop. From the above, when a predetermined number requesting a change of the call state is received, a message of guidance for requesting data input is transmitted to the terminal 2 other than the desired portable terminal 1, and after transmitting the message, the desired When the number and password of the desired mobile terminal 1 are input from a terminal 2 other than the mobile terminal 1, the desired mobile terminal 1

In this example, settings for preventing unauthorized use can be made in the mobile terminal 1.

First, the user of the portable terminal 1 which is a desired portable terminal receives the number of the portable terminal 1 and the called sub address from the second terminal 2 which is a terminal other than the desired portable terminal capable of setting the called sub address. Dial. here,
The destination sub-address shall include at least a password. The call from the second terminal 2 is transmitted to the exchange 5 and the base station 4, and transmitted from the base station 4 to the portable terminal 1 by a wireless line (see FIG. 5).

In portable terminal 1, when an incoming call is detected (see step 300 in FIG. 6), the received destination address is analyzed (see step 302 in FIG. 6). That is, the personal identification number is extracted from the destination sub-address. Next, data (personal identification number) collation is performed to determine whether or not this personal identification number matches the one set in advance in a storage means (not shown) of the portable terminal 1 constituted by a nonvolatile memory or the like (FIG. Step 3 of 6
04). If it is determined that they coincide with each other, the call is stopped and the ringing tone for this incoming call is not generated (see step 306 in FIG. 6).
On the other hand, when it is determined that the data does not match, the normal operation state is set (see step 308 in FIG. 6). That is, in this case, a ringing tone is generated in response to an incoming call from the second terminal 2, and a normal call state is established when the user goes off-hook.

The release of the call suspension can be performed by inputting a predetermined number or pressing a predetermined key on the portable terminal 1.
As described above, the mobile terminal according to the present embodiment is the mobile terminal 1 configured to be connected to the exchange 5 that performs circuit switching via a wireless line. The mobile terminal 1 receives the number and the password of the mobile terminal 1 dialed by the terminal 2
Is determined to match the number and password of the portable terminal 1 set in the storage means in advance, the call is stopped without generating a ringing tone, and it is determined that the passwords do not match. In such a case, a ringing tone is generated and a normal operation state is set.

Therefore, it is possible to perform the setting of the call stop of the portable terminal and the release of the call stop by the predetermined operation on the user side without going through the setting work by the communication carrier. In addition, it is possible to prevent a third party from easily setting the call suspension and releasing the call suspension. Further, it is possible to provide a mobile terminal capable of setting a call stop and canceling the call stop without any time limit.

[0048]

As described above, according to the present invention, it is possible to set or cancel the call suspension of the portable terminal by a predetermined operation on the user side without going through the setting work by the communication carrier. With this configuration, it is easy for the user to set and cancel the call suspension that conventionally required complicated procedures, and the convenience of the portable terminal can be further improved. Further, in setting and canceling the call stop, unlike the related art, there is no time limit, and the call can be always performed when desired, so that the call stop can be quickly set and canceled. Furthermore, since a password is used for setting and canceling the call suspension, a third party cannot easily set and cancel the call suspension unless the security code is known. Unauthorized use can be prevented. Further, since the setting of the call suspension is set or canceled by the operation on the user side, the burden of the setting work on the communication carrier side as in the related art is reduced, thereby further improving the communication service. It becomes possible.
