  When receiving an authentication result as a response to the authentication request from the first wireless terminal, the application unit applies the communication service related to the second wireless terminal based on the authentication result.

  Therefore, according to the present invention, the user of the first wireless terminal already subscribed to the communication service operates the wireless terminal and transmits the authentication result, so that the second wireless service unsubscribed to the second communication service is subscribed in real time. The application of the communication service can be executed for the wireless terminal. Even during communication, the communication service can be used immediately as long as it is within the communication service application area. As a result, it is possible to omit a procedure for using a communication service in advance by the user.

  The mobile communication system according to the present invention further includes a detection unit that detects the movement of each of the first and second wireless terminals, and the recognition unit includes the first wireless terminal and the second wireless terminal. When the second wireless terminal detects that the second wireless terminal has moved during communication, the second wireless terminal recognizes whether or not the second wireless terminal exists in the communication service application area.

In the present invention, when the detection unit detects that the second wireless terminal has moved, it is recognized whether or not the second wireless terminal exists within the application area of the communication service, and the application of the communication service is performed. When it is recognized that it exists in the area, an authentication request is transmitted to the first wireless terminal.

  Therefore, according to the present invention, even when the first wireless terminal and the second wireless terminal are communicating, the application of the communication service can be executed in real time by detecting the movement of the wireless terminal. it can. That is, even when the second wireless terminal moves into the communication service application area while communicating without applying the communication service, the communication service can be used immediately. .

[Operation example]
Next, an operation example of the mobile communication system in the first embodiment will be described with reference to FIG. FIG. 4 is a diagram showing an outline of the operation of the mobile communication system when a call is made from a non-service-subscribed terminal to a subscribed terminal in the service application area.

  In the example of FIG. 4, the base station 20 supports the cell # 01, the base station 21 supports the cell # 02, the base station 22 supports the cell # 03, and the cell # 02 and the cell # 03 respectively This is the applicable area X of the service x requested by the user. Further, the wireless terminal 50 is not subscribed to the service x and is located in the cell # 02. On the other hand, the wireless terminal 51 has already subscribed to the service x and is located in the cell # 03.

  In this case, the information in the home memory 30 is as shown in FIGS. That is, as “location information”, cell # 02 and cell # 03 are registered in the service application area of service x (see FIG. 2). As “subscriber information” and “service information”, the wireless terminal 50 is in an “applied service = none” and “service x = not subscribed” state, and the wireless terminal 51 is “applied service = service x”, The state is “service x = contract at subscription” (see FIG. 3).

  When a call is made from the wireless terminal 50 to the wireless terminal 51 under such conditions, the wireless terminal 50 is connected to the mobile communication switching center 10 via the base station 21 that supports the cell # 02 ( (1) shown in FIG. At this time, the connection control unit 12 of the mobile communication switching center 10 reads “location information”, “subscriber information”, and “service information” for the wireless terminals 50 and 51 from the home memory 30 (shown in FIG. 4 ( 2)). The connection control unit 12 connects the wireless terminal 50 and the wireless terminal 51 ((3) shown in FIG. 4).

  When the wireless terminal 50 and the wireless terminal 51 are connected, the location management unit 11 of the mobile communication switching center 10 determines the cell (cell) in which the wireless terminal 51 is located based on the information read by the connection control unit 12. # 03) is present in the service application area X of the service x to which the wireless terminal 51 subscribes. Similarly, the location management unit 11 recognizes the cell (cell # 02) in which the calling wireless terminal 50 is located and determines whether or not the cell (cell # 02) is in the service x application area X. to decide. If the location management unit 11 determines that the wireless terminals 50 and 51 exist in the service x application area X based on the above determination, the location management unit 11 instructs the authentication control unit 14 to perform service application authentication.

  Upon receiving this service application authentication instruction, the authentication control unit 14 transmits a “service application authentication request” to the wireless terminal 51 on the caller side ((4) shown in FIG. 4). This “service application authentication request” is a request for causing the wireless terminal to select whether or not to apply the target service. This “service application authentication request” may be voice information for selecting whether to apply a service, as shown in FIG. 5, or may be an application that displays a selection screen.

  When the wireless terminal 51 receives the “service application authentication request” from the mobile communication switching center 10, the wireless terminal 51 becomes in a selectable state as to whether or not to apply the service x to the wireless terminal 50 that is a non-service subscriber terminal. The selectable state here may be, for example, a state where a voice message is flowing when voice is transmitted from the mobile communication switching center 10 as described above. When an application is transmitted, the application may be activated and a selection screen may be displayed.

That is, a voice message or the like prompting selection from the authentication options shown in FIG. The user of the wireless terminal 51 selects whether to allow the service x from the authentication option to the counterpart wireless terminal 50 (S80). Then, the “service application authentication result” selected by the user is transmitted to the mobile communication switching center 10 (S81). For example, when the user of the wireless terminal 51 performs an operation of selecting “allow service only during main communication” (S80), the wireless terminal 51 sends a “service application authentication result” to the mobile communication switching center 10. Information indicating “service allowed only during main communication” is transmitted (S81).

  The authentication control unit 14 of the mobile communication switching center 10 determines the content of the “service application authentication result” from the wireless terminal 51 (S82). If it is determined that the “service application authentication result” indicates that the service is permitted, the authentication control unit 14 updates information on the wireless terminal 50 in the home memory 30 (S83). For example, when this determination is “service allowed only during main communication”, the authentication control unit 14 sets “subscriber information” application service for the wireless terminal 50 in the home memory 30 as “ “Service x” is set to “service allowed only during main communication” in the service x of “service information” (S83), and the wireless terminal 50 can immediately apply the service x.

  As described above, in this embodiment, when a service-subscribed terminal that has performed service application authentication moves from the service application area to the service application area, the terminal moves according to the handover request notified from the wireless terminal. If the previous cell is not service-applied, the service application is canceled for the radio terminal to which the radio terminal applied the service by service authentication. Accordingly, when the wireless terminal that has performed service application authentication moves out of the service application area, the service application can be canceled in real time.

[Seventh embodiment]
Next, the mobile communication system in the seventh embodiment of the present invention will be described below. In the mobile communication system according to the seventh embodiment, the service x is continuously applied to the wireless terminal 50 during the authentication procedure of the wireless terminal 51 by the system operation of any of the first to fourth embodiments described above. This is an example when it is permitted.

〔System configuration〕
The mobile communication system in the seventh embodiment is composed of functional units similar to those in the first embodiment, and operations in the respective functional units are slightly different. The functional unit that operates differently from the first embodiment will be described in the following operation example section.

[Operation example]
An operation example of the mobile communication system in the seventh embodiment will be described with reference to FIG. FIG. 18 is a diagram showing an outline of the operation of the mobile communication system when a non-subscriber terminal that has been allowed to apply service x for a certain period of time moves in / out of the service application area. In the example of FIG. 18, the base station, the cells supported by the base station, the cells belonging to the service application area, and the like are the same as in the above-described embodiment.

  The wireless terminal 50 that has not subscribed to the service is permitted to apply the service for a certain period of time by the wireless terminal 51 that has subscribed to the service, and is communicating with the wireless terminal 51 within the service x application area X. The operation so far is the same as that of the above-described embodiment.

In this embodiment, the wireless terminal 51 that has received the “service application authentication request” ((1) in FIG. 18) exchanges mobile communication with the wireless terminal 50 as “authenticated for a certain period of time” as an authentication result. The station 10 is notified ((2) in FIG. 18). As a result, the mobile communication switching center 10 that has received the authentication result updates the information related to the wireless terminal 50 in the home memory 30 ((3) in FIG. 18). The state of the subscriber information / service information table at this time is shown in FIG. That is, for the wireless terminal 50, “service x” is set as an application service of “subscriber information”,
“Allow service for a certain period” is set in the service x of “service information”.

  In such a communication state, when the wireless terminal 50 moves out of the service x application area (arrow 182), the location management unit 11 of the mobile communication switching center 10 recognizes the serving cell of the wireless terminal 50. ((4) shown in FIG. 18). Thereafter, the location management unit 11 notifies the authentication control unit 14 of an application change instruction for the service x.

  Upon receiving the service x application change instruction, the authentication control unit 14 reads “subscriber information” and “service information” regarding the wireless terminal 50 from the home memory 30 ((5) shown in FIG. 18). When the authentication control unit 14 confirms from the read information that the service x is in the “service allowed for a certain period” state, the authentication control unit 14 does not update the information in the home memory 30 and continues the application state of the service x. .

  When the wireless terminal 50 that has once moved out of the service x application area X has moved again into the service x application area X (arrow 181), the location management unit 11 indicates that the wireless terminal 50 is in the service application state. And that the cell in which the wireless terminal 50 is located is within the application area X of the service x ((6) in FIG. 18). When the wireless terminal 50 is in the service x application state and the serving cell of the wireless terminal 50 is in the service x application area X, the service x is applied without the authentication procedure being processed.

  Further, when the wireless terminal 50 and the wireless terminal 51 are communicating by applying the service x, when the communication between the wireless terminal 50 and the wireless terminal 51 is disconnected, the wireless terminal 50 transmits a call disconnection instruction ((7 in FIG. 18). )).

  Upon receiving this call disconnection instruction, the connection control unit 12 of the mobile communication switching center 10 notifies the authentication control unit 14 of an application change instruction for the service x. Upon receiving this service application change instruction, the authentication control unit 14 reads “subscriber information” and “service information” from the home memory 30 ((8) in FIG. 18).

  If the authentication control unit 14 determines from the read information that the service x is set to the “permitted service for a certain period of time” state, the authentication control unit 14 sets the service “x” for a certain period of time (home). The information in the memory 30 is not updated) ((9) in FIG. 18).

<Operation flow>
Hereinafter, the details of the operation flow of the mobile communication system under the above-described operation state of FIG. 18 will be described with reference to FIGS. FIG. 20 is a diagram showing an operation sequence of the mobile communication system in a case where an original service non-participating terminal permitted to apply service x for a certain period of time moves out of the service application area. FIG. 21 is a diagram showing an operation sequence of the mobile communication system in a case where an original service non-participating terminal permitted to continuously apply service x for a certain period returns to the service application area.

  First, regarding the subscriber information / service information table stored in the home memory 30, “applicable service = none” is set as “subscriber information” for the wireless terminal 50, and “service x = “Not subscribed” is set.

  The operation sequence in which the authentication control unit 14 of the mobile communication switching center 10 transmits a “service application authentication request” to the wireless terminal 51 is the same as in the above-described embodiment.

In the present embodiment, in the wireless terminal 51 that has received the “service application authentication request” (S201) from the mobile communication switching center 10, the user selects “allow service for a certain period of time” for the wireless terminal 50 that has not subscribed to the service. An operation is performed (S202). For example, according to the example shown in FIG. 5, “Option 2. Allow service for a certain period” is selected. The wireless terminal 51 notifies the mobile communication switching center 10 of the “service application authentication result” in which “service permission for a certain period” is set (S203).

  Upon receiving this “service application authentication result”, the authentication control unit 14 determines the content of the “service application authentication result” and updates the information related to the wireless terminal 50 in the home memory 30 (S204, S205). The state of the subscriber information / service information table at this time is shown in FIG. That is, for the wireless terminal 50, “service x” is set as the application service of “subscriber information”, and “service allowance for a certain period” is set as the service x of “service information”. As a result, the wireless terminal 50 can immediately apply the service x for a certain period. Thereafter, the wireless terminal 50 and the wireless terminal 51 communicate by applying the service x.

  Next, the operation of the mobile communication system when the wireless terminal 50 communicating with the wireless terminal 51 moves to the cell # 01 outside the service x application area in the above state will be described.

  The wireless terminal 50 notifies the handover request to the connection control unit 12 of the mobile communication switching center 10 (S206).

  Upon receiving the handover request, the connection control unit 12 recognizes that the service x is being applied, and instructs the location management unit 11 to perform “service application determination” (S207).

  When the location management unit 11 recognizes that the wireless terminal 50 is in the service x application state and the cell # 01 in which the wireless terminal 50 is located is outside the service application area (S208), the location management unit 11 notifies the authentication control unit 14 that “service "Apply change" is instructed (S209).

  The authentication control unit 14 reads “subscriber information” and “service information” regarding the wireless terminal 50 in the home memory 30 (S210). When the authentication control unit 14 recognizes from the read information that “service is allowed for a certain period” for the service x (S211), the information in the home memory 30 is used to continue the application of the service x. Is not changed (S212). That is, the state shown in FIG. 19 is maintained.

  Next, an operation sequence when the wireless terminal 50 that has once moved out of the service x application area X returns to the cell # 02 in the service x application area X will be described with reference to FIG.

  When the wireless terminal 50 returns to the cell # 02 in the service x application area X again, the wireless terminal 50 transmits a handover request to the connection control unit 12 of the mobile communication switching center 10 (S215).

  When receiving the handover request, the connection control unit 12 instructs the location management unit 11 to perform “service application determination” (S216). The location management unit 11 determines whether the cell # 02 in which the wireless terminal 50 is located is in the service x application area X and whether the wireless terminal 50 is in the service x application state (S217). ). If the location management unit 11 recognizes that the wireless terminal 50 is located in the service x application area X and is in the service x application state based on the above determination, the location management unit 11 does not instruct the service application change, The application of x is continued (S218).

  Next, the operation of the mobile communication system when communication between the wireless terminal 50 and the wireless terminal 51 that are in communication is disconnected due to application of a service will be described.

When communication with the wireless terminal 51 is disconnected, the wireless terminal 50 that is communicating by applying the service is disconnected.
A call disconnection instruction is transmitted to the mobile communication switching center 10 (S220). Upon receiving this call disconnection instruction, the connection control unit 12 of the mobile communication switching center 10 recognizes that the wireless terminal 50 is in the service application state, and instructs the authentication control unit 14 to change service application.

  The authentication control unit 14 reads “subscriber information” and “service information” regarding the wireless terminal 50 in the home memory 30 (S222). When the authentication control unit 14 determines from the read information that the service x is set to “allow service for a certain period” (S223), the service control state is changed according to the service application period (S224).

  Note that the “certain period” determined here may be stored in the home memory 30 as with other information. For example, when this “predetermined period” is set to “during the communication”, the application state of the service x may be canceled when the call is disconnected. Further, the authentication control unit 14 may monitor the application period and update the information in the home memory 30 to change the application state of the service x when the application period expires.

<Operation / Effect in Seventh Embodiment>
As described above, the mobile communication system according to the seventh embodiment operates as follows when a service-subscribed terminal permits a service non-participating terminal to continuously apply the service for a certain period of time.

  Upon receiving a “service application authentication result” in which “service permission for a certain period” is set from the wireless terminal 51, the mobile communication switching center 10 sends information on the wireless terminal 50 in the home memory 30 to “service x = service for a certain period of time”. Update as “allowed”.

  In this state, the mobile communication switching center 10 recognizes that the wireless terminal 50 communicating with the wireless terminal 51 has moved out of the service x application area, and that the wireless terminal 50 is in the service x application state. When the determination is made, “authentication service change” is instructed to the authentication control unit 14. When the authentication control unit 14 recognizes that “service is allowed for a certain period of time” for the service x based on the information regarding the wireless terminal 50 in the home memory 30, the authentication control unit 14 stores the service x in the home memory 30. Do not change the information.

  Further, when the wireless terminal 50 returns to the service x application area X, the mobile communication switching center 10 is in the service x application area X and the service x application is applied. Recognizing that it is in the middle state, the service application change is not instructed and the application of the service x is continued.

  Thereby, even if the wireless terminal 50 permitted to apply the service for a certain period of time moves within / outside the service application area, the wireless terminal 50 can immediately receive the application of the service. In this case, the service application authentication process is not required each time.

  Similarly, when the communication between the wireless terminal 50 and the wireless terminal 51 in communication is disconnected due to the application of the service, the application of the service is maintained for a certain period of time.

[Eighth embodiment]
Next, the mobile communication system in the eighth embodiment of the present invention will be described below. The mobile communication system apparatus according to the eighth embodiment is an example when service applicability is set in advance in the mobile communication system.

〔System configuration〕
The mobile communication system in the eighth embodiment is composed of the same functional units as those in the first embodiment, and operations in the respective functional units are slightly different. The functional unit that operates differently from the first embodiment will be described in the following operation example section.

[Operation example]
An operation example of the mobile communication system in the eighth embodiment will be described with reference to FIG. FIG. 22 is a diagram showing an outline of the operation of the mobile communication system when service application authentication is performed in advance. In the example of FIG. 22, the base station, the cell supported by the base station, the cell belonging to the service application area, and the like are the same as in the above-described embodiment.

  The wireless terminal 50 is not subscribed to the service, and the wireless terminal 51 is subscribed to the service. Thereby, the information regarding the wireless terminals 50 and 51 in the home memory 30 is in the state shown in FIGS. That is, for the wireless terminal 50, “applied service = none” is set as the subscriber information, and “service x = not subscribed” is set as the service information.

  The service-added wireless terminal 51 recognizes identification information (for example, a telephone number) of the wireless terminal 50 that is a communication partner. In this case, when the wireless terminal 51 wants to apply the service x to the wireless terminal 50, the wireless terminal 51 performs an operation of service application authentication on the wireless terminal 50 before communicating with the wireless terminal 50. At this time, the service application authentication operation by the wireless terminal 51 may be performed in response to a voice message as shown in FIG. 5 from the mobile communication switching center 10, or an application installed in the wireless terminal 51 may be selected. It may be activated and operated.

  When the service application authentication operation is performed by the wireless terminal 51, “service application authentication registration” is notified from the wireless terminal 51 ((1) in FIG. 22). Upon receiving this notification, the mobile communication switching center 10 sets “service x” as the application service of “subscriber information” in the home memory 30 for the wireless terminal 50, and sets “area” as the service x of “service information”. The service permission "is automatically set in ((2) of FIG. 22). The state of the subscriber information / service information table in the home memory 30 after the update is shown in FIG.

  As a result, as in the previous embodiment, the service x can be automatically applied to the wireless terminal 50 automatically without transmitting a “service application authentication request” to the wireless terminal 51 that has subscribed to the service. It becomes possible.

<Operation flow>
Hereinafter, the details of the operation flow of the mobile communication system under the above-described operation state of FIG. 22 will be described with reference to FIG. FIG. 24 is a diagram showing an operation sequence of the mobile communication system when service application authentication is performed in advance.

  First, regarding the subscriber information / service information table stored in the home memory 30, “applicable service = none” is set as “subscriber information” for the wireless terminal 50, and “service x = “Not subscribed” is set.

  The wireless terminal 51 already subscribed to the service notifies the service application authentication registration together with the identification information (for example, telephone number) of the wireless terminal 50 before communicating with the wireless terminal 50 that is the communication partner (S231).

Upon receiving the “service application authentication registration”, the authentication control unit 14 of the mobile communication switching center 10 sets “service x” as the application service of the “subscriber information” in the home memory 30 for the wireless terminal 50, “Service is automatically allowed in the area” for service x in “Service Information”
Is set (S232). The subscriber information / service information table in the updated home memory 30 is as shown in FIG.

  In such a system state, when there is a call from the wireless terminal 50 located in the cell # 02 to the wireless terminal 51 that has already subscribed to the service, the mobile communication system operates as follows.

  When the wireless terminal 50 transmits to the wireless terminal 51, a transmission request is transmitted to the mobile communication switching center 10 (S233). The connection control unit 12 of the mobile communication switching center 10 reads “location information”, “subscriber information”, and “service information” of the wireless terminals 50 and 51 from the home memory 30 (S234). The connection control unit 12 requests the wireless terminal 51 for incoming connection (S235). Subsequently, the connection control unit 12 instructs the service control unit 13 to perform service control (S236).

  The service control unit 13 acquires the service information to which the wireless terminal 51 subscribes from the “subscriber information” and “service information” read by the connection control unit 12, and the wireless terminal 51 has subscribed to the service x. It is recognized that the wireless terminal 50 is in the “automatic service permission in area” state for the service x (S237). Based on this recognition, the service control unit 13 notifies the location management unit 11 of service x application area determination (S238).

  The location management unit 11 determines whether or not the cell # 02 in which the wireless terminal 50 is located is within the service x application area X (S239). The wireless terminal 50 can immediately apply the service x without making an inquiry to 51.

<Operation / Effect in Eighth Embodiment>
As described above, the mobile communication system according to the eighth embodiment operates as follows when a service-subscribed terminal permits service application to a service non-subscriber terminal in advance.

  The wireless terminal 51 already subscribed to the service registers in advance “automatic service permission within the area” in the mobile communication switching center 10 for the wireless terminal 50. As a result, when the wireless terminal 50 transmits to the wireless terminal 51 within the service application area, the mobile communication switching center 10 does not request the wireless terminal 51 for service application authentication, and registers in the home memory 30. The application of the service can be executed based on the information.

  Therefore, by registering information relating to service application in advance, the mobile communication system can immediately execute service application without requesting service application authentication each time.
