  The subscriber information management unit 63 communicates with the MSC / VLRs 5a and 5b to manage the subscriber information stored in the subscriber information storage unit 62.

(2) Configuration of MSC / VLR:
FIG. 4 is a functional block diagram showing the configuration of the MSC / VLR 5a. As shown in FIG. 4, the MSC / VLR 5 a includes a communication I / F 51, a subscriber information storage unit 52, a subscriber information management unit 53, a group registration unit 54, and a connection control unit 55.

  The communication I / F 51 functions as an interface with the NMSCP / HLR 6 and the RNC 4a.

  The subscriber information storage unit 52 stores subscriber information of a mobile station (for example, mobile station 1) located in the location registration area A1. The subscriber information includes a telephone number, IMSI, and TMSI.

  The subscriber information management unit 53 manages the subscriber information stored in the subscriber information storage unit 52 in response to a location registration request from the mobile station 1 or an instruction from the NMSCP / HLR 6.

  The group registration unit 54 performs group registration of the USIMs 101a to 101c in response to a group registration request from the mobile station 1. The group registration unit 54 registers the USIM 101a as a USIM representing the USIMs 101a to 101c.

  The connection control unit 55 executes call control for the mobile station 1, that is, outgoing control and incoming control. For example, when there is an incoming call to the USIMs 101a to 101c registered in the group, the connection control unit 55 determines whether the mobile station 1 is communicating with any telephone number, and responds to the incoming call according to the determination result. Perform incoming call control.

(Operation of mobile communication system)
Next, the operation of the mobile communication system according to this embodiment will be described with reference to FIGS.

(1) Mobile station operation overview:
FIG. 5 is a flowchart showing an outline of the operation of the mobile station 1. Here, the operation immediately after the USIMs 101a to 101c are mounted on the mobile station 1 will be described.

  In step S101, the mobile station 1 selects a representative USIM (here, USIM 101a) from the USIMs 101a to 101c.

  In step S102, the mobile station 1 transmits a location registration request to the mobile communication network 7A using the subscriber information stored in the representative USIM (USIM 101a). Specifically, the mobile station 1 transmits the location registration area identification information obtained from the base station 3a to the MSC / VLR 5a using the IMSI. As a result, the TMSI is assigned from the MSC / VLR 5 a to the mobile station 1, and the TMSI is stored in the mobile station 1.

  In step S103, the mobile station 1 sends a group registration request for subscriber information stored in the USIMs 101a to 101c in a wireless communication procedure using the subscriber information stored in the representative USIM (USIM 101a) in step S102. It transmits to MSC / VLR 5a using the acquired TMSI.

  In step S104, the mobile station 1 executes location registration processing and call processing based on the subscriber information stored in the representative USIM (USIM 101a) and the TMSI acquired in step S102.

(2) Outline of operation of mobile communication network:
FIG. 6 is a flowchart showing an outline of the operation of the mobile communication network 7A (MSC / VLR 5a and NMSCP / HLR 6).

  In step S201, the MSC / VLR 5a receives a location registration request from the mobile station 1 and executes location registration of the mobile station 1 (USIM 101a). The MSC / VLR 5a requests the NMSCP / HLR 6 to register the location of the mobile station 1 (USIM 101a). As a result, the NMSCP / HLR 6 stores the identification information of the MSC / VLR 5a as the location information of the mobile station 1. The MSC / VLR 5a receives the subscriber information of the mobile station 1 (USIM 101a) from the NMSCP / HLR 6 and stores the received subscriber information.

  In step S202, the MSC / VLR 5a receives the USIM 101a to 101c group registration request from the mobile station 1, and executes the USIM 101a to 101c group registration. Specifically, the MSC / VLR 5a registers the USIM 101a as a group representative, and stores the USIM 101a information in association with the USIM 101a information.

  In step S203, the MSC / VLR 5a executes mobility management and call processing for the representative USIM (USIM 101a).

(3) Operation sequence of mobile station 1 and mobile communication network 7A:
FIG. 7 is a sequence diagram showing an operation sequence of the mobile station 1 and the mobile communication network 7A. Here, an operation when a call is made from the mobile station 2 to the mobile station 1 will be described.

  In step S301, the mobile station 1 transmits a location registration request to the mobile communication network 7A (MSC / VLR 5a). The location registration request includes the IMSI (ID1) of the USIM 101a.

  In step S302, the mobile communication network 7A (MSC / VLR 5a) performs location registration of the mobile station 1 (USIM 101a).

  In step S303, the mobile station 1 transmits a group registration request for USIMs 101a to 101c to the mobile communication network 7A (MSC / VLR 5a). The group registration request includes the IMSI (ID1) of the USIM 101a or the TMSI assigned to the USIM 101a and the IMSIs (ID2, ID3) of the USIM 101b and the USIM 101c.

  In step S304, the mobile communication network 7A (MSC / VLR 5a) performs the above-described group registration for the USIMs 101a to 101c.

  In step S305, the mobile station 2 transmits a connection request (circuit-switched call) for the USIM 101b to the mobile communication network 7A (MSC / VLR 5b). For example, the connection request includes a telephone number corresponding to the USIM 101b. The MSC / VLR 5b inquires the NMSCP / HLR 6 about the location registration area (VLR identification information) where the mobile station 1 is located, and then transmits a connection request (circuit-switched call) to the MSC / VLR 5a.

  In step S306, the MSC / VLR 5a converts the connection request for the USIM 101b into a connection request for the representative USIM (USIM 101a).

  In step S307, the mobile communication network 7A (MSC / VLR 5a) transmits a connection request to the representative USIM (USIM 101a).

  In step S308, communication (call) is started between the mobile station 1 and the mobile station 2.

(Action / Effect)
According to the present embodiment, the mobile station 1 requests the MSC / VLR 5a to register the location of the representative USIM (USIM 101a) among the USIMs 101a to 101c. After the location registration is completed, the mobile station 1 requests the MSC / VLR 5a to perform group registration for the USIMs 101a to 101c.

  Therefore, the mobile station 1 can collectively register the USIMs 101a to 101c in the MSC / VLR 5a without individually registering them in the MSC / VLR 5a. Therefore, the mobile station 1 can reduce the processing load and communication sequence on the mobile communication network 7A side required for registration of the USIMs 101a to 101c.

  Further, according to the present embodiment, the MSC / VLR 5a receives a group registration request from the mobile station 1 and registers the USIMs 101a to 101c as a group. When there is an incoming call for any of the USIMs 101a to 101c group-registered by the group registration unit, the MSC / VLR 5a performs incoming control for the mobile station 1 using information on the representative USIM (USIM 101a).

  Therefore, the MSC / VLR 5a only needs to perform incoming control for the representative USIM (USIM 101a) among the USIMs 101a to 101c, and does not need to perform incoming control for all of the USIMs 101a to 101c. For this reason, it is possible to suppress an increase in processing load on the mobile communication network 7A side.

[Second Embodiment]
In the present embodiment, differences from the above-described first embodiment will be mainly described.

(Schematic configuration of mobile communication system)
FIG. 8 is an overall schematic configuration diagram of the mobile communication system according to the present embodiment. As shown in FIG. 8, the mobile communication network 7B is different from FIG. 1 in that it includes packet service nodes (SGSN) 8a and 8b. That is, the mobile communication network 7B according to the present embodiment supports the packet switching method in addition to the circuit switching method.

(Operation of mobile communication system)
Next, with reference to FIG.9 and FIG.10, operation | movement of the mobile communication system which concerns on this embodiment is demonstrated.

(1) Operation sequence of mobile station and mobile communication network (pattern 1):
FIG. 9 is a sequence diagram showing an operation sequence of the mobile station 1 and the mobile communication network 7B. Here, the mobile station 2 makes a call (circuit switching call) to the mobile station 1 (USIM 101b), and then the mobile station 3 makes a call (circuit switching call) to the mobile station 1 (USIM 101c). The operation in this case will be described.

  In step S401, the mobile station 1 transmits a location registration request to the mobile communication network 7B (MSC / VLR 5a, SGSN 8a). The location registration request includes the IMSI (ID1) of the USIM 101a.

  In step S402, the mobile communication network 7B (MSC / VLR 5a, SGSN 8a) performs location registration of the mobile station 1 (USIM 101a).

  In step S403, the mobile station 1 transmits a group registration request for USIMs 101a to 101c to the mobile communication network 7B (MSC / VLR 5a, SGSN 8a).

  In step S404, the mobile communication network 7B (MSC / VLR 5a, SGSN 8a) performs the above-described group registration for the USIMs 101a to 101c.

  In step S405, the mobile station 2 transmits a connection request (circuit-switched call) for the USIM 101b to the mobile communication network 7B (MSC / VLR 5b). The MSC / VLR 5b inquires the NMSCP / HLR 6 about the location registration area (VLR identification information) where the mobile station 1 is located, and then transmits a connection request (circuit-switched call) to the MSC / VLR 5a.

  In step S406, the MSC / VLR 5a converts the connection request for the USIM 101b into a connection request for the representative USIM (USIM 101a).

  In step S407, the mobile communication network 7B (MSC / VLR 5a) transmits a connection request to the representative USIM (USIM 101a).

  In step S408, communication (call) is started between the mobile station 1 and the mobile station 2.

  In step S409, the mobile station 3 transmits a connection request (circuit-switched call) for the USIM 101c to the mobile communication network 7B (MSC / VLR 5b). The MSC / VLR 5b inquires the NMSCP / HLR 6 about the location registration area (VLR identification information) where the mobile station 1 is located, and then transmits a connection request (circuit-switched call) to the MSC / VLR 5a.

  In step S410, the MSC / VLR 5a determines that the mobile station 1 is in communication (during a call) and rejects the connection request (circuit-switched call) for the USIM 101c.

(2) Operation sequence of mobile station and mobile communication network (pattern 2):
FIG. 10 is a sequence diagram showing an operation sequence of the mobile station 1 and the mobile communication network 7B. Here, the mobile station 2 makes a call (circuit switching call) to the mobile station 1 (USIM 101b), and then the mobile station 3 makes a call (packet exchange call) to the mobile station 1 (USIM 101c). The operation in this case will be described.

  In steps S501 to S508, an operation sequence similar to that in steps S401 to S408 in FIG. 9 is executed.

  In step S509, the mobile station 3 transmits a connection request (packet exchange call) for the USIM 101c to the mobile communication network 7B (SGSN 8b). The SGSN 8b inquires of the NMSCP / HLR 6 about the location registration area (VLR identification information) where the mobile station 1 is located, and then transmits a connection request (packet exchange call) to the SGSN 8a.

  In step S510, the SGSN 8a converts the connection request (packet exchange call) for the USIM 101c into a connection request (packet exchange call) for the representative USIM (USIM 101a).

  In step S511, the mobile communication network 7B (SGSN 8a) transmits a connection request (packet exchange call) to the representative USIM (USIM 101a).

(Action / Effect)
According to this embodiment, the MSC / VLR 5a is in the case where the mobile station 1 is communicating by an incoming call for any of the grouped USIMs 101a to 101c, and there is a new incoming call for another USIM. Determines whether to allow the new incoming call depending on whether the new incoming call is a circuit-switched call or a packet-switched call.

  Therefore, when the new incoming call is a packet-switched call, communication can be realized by using two USIMs simultaneously among the USIMs 101a to 101c.
