Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, a description will be given of a technology for determining whether a dual mode terminal supporting a communication service of two different communication services is provided in a wireless communication system.

In the following description, it is assumed that a dual mode terminal supports a service of a 3rd generation partnership project (3GPP) standard and a service of a 3GPP2 standard. However, even when the dual mode terminal supports the services of other communication standards, it may be determined whether the dual mode terminal provides the communication service. Here, the 3GPP standard is a communication service such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS), Wideband Code Division Multiple Access (WCDMA) / High Speed Packet Access (HSPA), and Long Term Evolution (LTE). Support. The 3GPP2 standard supports communication services such as 1x Radio Transmission Technology (1xRTT), High Rate Packet Data (HRPD), and evolved HRPD (eHRPD).

In the following description, it is assumed that the wireless communication system determines whether the dual mode terminal provides 3GPP service and 3GPP2 service using the dual mode terminal using International Mobile Subscriber Identify (IMSI) and Mobile Equipment IDentification (MEID). do. However, the wireless communication system may use IMEI (International Mobile Equipment Identify) or GUTI, which is a device ID defined in the 3GPP standard, instead of the IMSI. In addition, the wireless communication system may use a user identifier (UE ID) instead of the MEID. Here, the IMSI represents information stored in a subscriber information module (SIM / USIM) used in 3GPP, and the MEID represents a device ID defined in the 3GPP2 standard.

1 is a block diagram of a wireless communication system for determining whether a 3GPP service and a 3GPP2 service are provided by a dual mode terminal according to an exemplary embodiment of the present invention.

As shown in FIG. 1, the wireless communication system includes a home subscriber server (HSS) 100, a data base (DB) 110, a mobile switch 120, and a 3GPP base station Node B ( 122), an access network (AN) 130, a 3GPP2 base station (eNode B) 132, and a dual mode terminal 140.

The dual mode terminal 140 may access a 3GPP network using a 3GPP modem and access a 3GPP2 network using a 3GPP2 modem. For example, the dual mode terminal 140 accesses the 3GPP base station 122 using a 3GPP modem to receive 3GPP services, and accesses the 3GPP2 base station 132 using a 3GPP2 modem to provide 3GPP2 services. Receive.

If the 3GPP modem of the dual mode terminal 140 is activated so that the dual mode terminal 140 accesses the 3GPP base station 122, the mobile switch 120 is an IMSI of the dual mode terminal 140. And whether the 3GPP service and the 3GPP2 service are provided by the dual mode terminal 140 using the MEID. In this case, the mobile switch 120 determines whether to provide 3GPP service and 3GPP2 service of the dual mode terminal 140 by using the mapping table of IMSI and MEID managed by the home subscriber server 100, Only judge the availability. Here, the mobile switch 120 includes a Mobile Switching Center (MSC), a Serving GPRS Support Node (SGSN), or a Mobility Management Entity (MME).

Meanwhile, when the 3GPP2 modem of the dual mode terminal 140 is activated and the dual mode terminal 140 connects to the 3GPP2 base station 132, the access network 130 determines the MEID of the dual mode terminal 140. And whether the 3GPP service and the 3GPP2 service are provided by the dual mode terminal 140 using IMSI. In this case, the access network 130 determines whether to provide the 3GPP service and the 3GPP2 service of the dual mode terminal 140 by using the mapping table of IMSI and MEID managed by the home subscriber server 100, Only judge the availability.

The home subscriber server 100 performs subscriber service profile management, subscriber location management, and authentication data generation for supporting call processing in 3GPP and 3GPP2 networks. For example, the home subscriber server 100 includes a subscriber information processing unit 102 and a device number registration processing unit (EIR) 104. Here, the subscriber information processing device 102 includes a home location register (HLR) or a visitor location register (VLR).

The storage unit 110 stores information managed by the home subscriber server 100. For example, the storage unit 110 may include user identification information, user number, user address information, user authentication and authorization network access control information, user registration location information, and user profile information managed by the home subscriber server 100. And so on. In addition, the storage unit 110 stores a mapping table for IMSI and MEID (or ESN) of the dual mode terminal.

In the following description, a mobile switch of a 3GPP network and an access network of a 3GPP2 network, which determine whether to provide 3GPP service and 3GPP2 service of the dual mode terminal by using IMSI and MEID of the dual mode terminal, are referred to as a network management apparatus.

Referring to FIG. 2, first, in step 201, the network management apparatus determines whether the dual mode terminal requests to access the network.

If the dual mode terminal requests to connect to the network, the network management apparatus proceeds to step 203 and checks the first identification information of the dual mode terminal requesting the connection. In this case, the first identification information of the dual mode terminal represents identifier information defined in a network to which the dual mode terminal requests connection. That is, when the dual mode terminal requests to connect to the 3GPP network, the first identification information of the dual mode terminal indicates IMSI. On the other hand, when the dual mode terminal requests to connect to the 3GPP2 network, the first identification information of the dual mode terminal indicates the MEID.

In step 205, the network management apparatus determines whether the first identification information of the dual mode terminal is valid. For example, the network management apparatus determines the validity of the first identification information by transmitting the first identification information of the dual mode terminal to a home subscriber server.

If the home subscriber server determines that the first identification information is not valid, the network management apparatus proceeds to step 215 and rejects the access request of the dual mode terminal. That is, the network management apparatus rejects the access request of the dual mode terminal to prevent providing the 3GPP service and the 3GPP2 service to the dual mode terminal.

On the other hand, if the home subscriber server determines that the first identification information is valid, the network management apparatus proceeds to step 207 and requests the dual mode terminal for the second identification information of the dual mode terminal. Here, the second identification information of the dual mode terminal represents identifier information defined in a network which does not request connection among two networks supported by the dual mode terminal. That is, when the dual mode terminal requests to connect to the 3GPP network, the second identification information of the dual mode terminal indicates the MEID. On the other hand, when the dual mode terminal requests to connect to the 3GPP2 network, the second identification information of the dual mode terminal indicates the IMSI.

In step 209, the network management apparatus determines whether the second identification information of the dual mode terminal is received from the dual mode terminal.

When receiving the second identification information of the dual mode terminal from the dual mode terminal, the network management apparatus proceeds to step 211 and checks whether the first identification information and the second identification information are mapped. For example, the network management apparatus transmits first identification information and second identification information of the dual mode terminal to a home subscriber server. The home subscriber server checks whether the first identification information and the second identification information of the dual mode terminal provided from the network management apparatus are mapped using the mapping table. Here, the mapping table means a table including mapping information of the first identification information and the second identification information of the dual mode terminals.

If the home subscriber server determines that the first identification information and the second identification information of the dual mode terminal are mapped, the base station management server proceeds to step 213 and accepts the access request of the dual mode terminal. That is, the network management apparatus accepts the access request of the dual mode terminal to provide 3GPP service and 3GPP2 service to the dual mode terminal.

On the other hand, if the home subscriber server determines that the first identification information and the second identification information of the dual mode terminal are not mapped, the base station management server proceeds to step 215 and rejects the access request of the dual mode terminal. That is, the network management apparatus rejects the access request of the dual mode terminal to prevent providing the 3GPP service and the 3GPP2 service to the dual mode terminal.

Hereinafter, a description will be given of a signal flow for determining whether a dual mode terminal provides a 3GPP service and a 3GPP2 service in a dual mode terminal, a network management apparatus, and a home subscriber server. In the following description, it is assumed that the first identification information of the dual mode terminal is valid.

As shown in FIG. 3, when the 3GPP modem 304 of the dual mode terminal 300 is powered on (step 341), the 3GPP modem 304 is a network management apparatus 310 of a 3GPP network. Request a connection (step 343). In this case, the 3GPP modem 304 transmits an Attach Request message including the IMSI of the dual mode terminal 300 to the network management device 310. Here, the network management apparatus 310 of the 3GPP network is configured to include at least one of the MSC, MME, SGSN (Serving GPRS Support Node). In addition, the access request message may be configured in the same manner as the access request message defined in the 3GPP standard.

If it is determined that the IMSI provided from the 3GPP modem 304 is valid, the network management device 310 requests an identifier of the 3GPP2 modem 302 from the 3GPP modem 304 (step 345). For example, the network management apparatus 310 requests an identifier of the 3GPP2 modem 302 using an identifier request message defined in the 3GPP standard.

The 3GPP modem 304 requests a MEID to the 3GPP2 modem 302 according to the 3GPP2 modem 302 identifier request of the network management apparatus 310 (step 347).

The 3GPP2 modem 302 transmits the MEID used in the protocol stack software to the 3GPP modem 304 according to the request of the 3GPP modem 304 (step 349).

The 3GPP modem 304 transmits the MEID provided from the 3GPP2 modem 302 to the network management device 310 (step 351). For example, the 3GPP modem 304 transmits the MEID of the 3GPP2 modem 302 to the network management device 310 using an identifier response message defined in the 3GPP standard configured as shown in Table 1 below. .

IEI Information Element Type / Reference Presence Format Length

Here, the 3GPP modem 304 may add the MEID of the 3GPP2 modem 302 to the mobile identity information element field and transmit it to the network management device 310.

The network management apparatus 310 requests a mapping table confirmation request to the device number registration processing unit (EIR) 324 of the home subscriber server 320 to check whether the IMSI and the MEID of the dual mode terminal 300 are mapped. Request Check Mapping table) signal is transmitted (step 353).

The device number registration processing device 324 checks the mapping relationship between the IMSI and the MEID of the dual mode terminal 300 by searching the mapping table stored in the storage unit 330 according to the request of the network management device 310. (Step 355). Here, the mapping table means a table including mapping information of IMSI and MEID of the dual mode terminals.

The device number registration processing device 324 transmits the mapping information of IMSI and MEID of the dual mode terminal 300 to the network management device 310 by searching and confirming the mapping table (step 357).

When the network management device 310 receives the mapping information of the IMSI and the MEID of the dual mode terminal 300 from the device number registration processing device 324, the 3GPP modem to authenticate the 3GPP modem 304. In step 359, the authentication request signal is transmitted. At this time, the authentication for the 3GPP modem 304 represents a mutual authentication process using an encryption key.

The 3GPP modem 304 transmits a response signal for the authentication request of the network management device 310 to the network management device 310 (step 361).

At this time, the network management device 310 and the home subscriber server 320 performs an authentication procedure defined in the 3GPP standard (step 363).

After the network management device 310 completes the mutual authentication procedure for the 3GPP modem 304, mapping information of IMSI and MEID of the dual mode terminal 300 received from the device number registration processing device 324. According to the 3GPP modem 304 to accept or reject the connection request. For example, when the IMSI and the MEID of the dual mode terminal 300 are mapped, the network management apparatus 310 of the 3GPP modem 304 to provide 3GPP service and 3GPP2 service to the dual mode terminal 300. Accept the connection request (step 371).

In another example, when the IMSI and the MEID of the dual mode terminal 300 are not mapped, the network management apparatus 310 may not provide the 3GPP service and the 3GPP2 service to the dual mode terminal 300. In step 381, the connection request is rejected.

4 illustrates a procedure for determining whether a 3GPP service and a 3GPP2 service are provided by a dual mode terminal in a wireless communication system according to another embodiment of the present invention.

As shown in FIG. 4, when the 3GPP modem 404 of the dual mode terminal 400 is powered on (step 441), the 3GPP modem 404 is a network management apparatus 410 of a 3GPP network. Request a connection (step 443). In this case, the 3GPP modem 404 transmits an Attach Request signal including the IMSI of the dual mode terminal 400 to the network management device 410. Here, the network management device 410 of the 3GPP network is configured to include at least one of the MSC, MME, SGSN. In addition, the access request message may be configured in the same manner as the access request message defined in the 3GPP standard.

If it is determined that the IMSI provided from the 3GPP modem 404 is valid, the network management device 410 requests the identifier of the 3GPP2 modem 402 from the 3GPP modem 404 (step 445). For example, the network management apparatus 310 requests an identifier of the 3GPP2 modem 302 using an identifier request message defined in the 3GPP standard.

The 3GPP modem 404 requests the MEID to the 3GPP2 modem 402 according to the 3GPP2 modem 402 identifier request of the network management apparatus 410 (step 447).

The 3GPP2 modem 402 transmits the MEID used in the protocol stack software to the 3GPP modem 404 according to the request of the 3GPP modem 404 (step 449).

The 3GPP modem 404 transmits the MEID provided from the 3GPP2 modem 402 to the network management device 410 (step 451). For example, the 3GPP modem 404 transmits the MEID of the 3GPP2 modem 402 to the network management device 410 using an identifier response message defined in the 3GPP standard configured as shown in Table 1 below. .

The network management device 410 requests a mapping table confirmation request to the device number registration processing unit (EIR) 424 of the home subscriber server 420 to check whether the IMSI and the MEID of the dual mode terminal 400 are mapped. Request Check Mapping table) is transmitted (step 453).

The device number registration processing unit 424 checks the mapping relationship between the IMSI and the MEID of the dual mode terminal 400 by searching the mapping table stored in the storage unit 430 according to the request of the network management device 410. (Step 455). Here, the mapping table means a table including mapping information of IMSI and MEID of the dual mode terminals.

The network management device 410 accepts or rejects the connection request of the 3GPP modem 404 according to the mapping information of IMSI and MEID of the dual mode terminal 400 provided from the device number registration processing device 424. .

If the IMSI and the MEID of the dual mode terminal 400 are mapped, the network management device 410 accepts the connection request of the 3GPP modem 404. Accordingly, the network management device 410 transmits an authentication request signal to the 3GPP modem 404 to authenticate the 3GPP modem 404 (step 461). At this time, the authentication for the 3GPP modem 404 represents a mutual authentication process using an encryption key.

The 3GPP modem 404 transmits a response signal to the network management device 410 to the network management device 410 in step 463.

3 and 4, the 3GPP modem adds the MEID to the mobile identity information element field of the identity response message defined in the 3GPP standard and transmits the MEID to the network management apparatus. That is, since the data lengths of the IMEI and the MEID of the dual mode terminal are the same as shown in FIG. 6, the 3GPP modem may add the MEID to the mobile identity information element field of the identifier response message so as not to violate the 3GPP standard. .

Here, the state information of the dual mode terminal 500 includes the IMSI and the MEID of the dual mode terminal 500.

The HLR / AuC / AAA 522 transmits a request check mapping table signal to the device number registration processing unit (EIR) 524 (step 555).

The device number registration processing unit 524 searches the mapping table stored in the storage unit 530 in response to a request of the network management device 510 and confirms the mapping relationship between the IMSI and the MEID of the dual mode terminal 500. (Step 557). Here, the mapping table means a table including mapping information of IMSI and MEID of the dual mode terminals.

The device number registration processing unit 524 uses the HLR / AuC / AAA 522 to map mapping information of the IMSI and MEID of the dual mode terminal 500 by searching the mapping table and confirming the network management device 510. (Step 559, 561).

The network management device 510 accepts or rejects the connection request of the 3GPP2 modem 502 according to the mapping information of IMSI and MEID of the dual mode terminal 500 provided from the HLR / AuC / AAA 522. .

If the IMSI and the MEID of the dual mode terminal 500 are mapped, the network management apparatus 510 may enable the network management apparatus 510 to provide 3GPP service and 3GPP2 service to the dual mode terminal 500. Accept the connection request of the 3GPP2 modem 502 (step 571).

On the other hand, if the IMSI and MEID of the dual mode terminal 500 is not mapped, the network management device 510 of the 3GPP2 modem 502 to prevent the 3GPP service and 3GPP2 service to provide to the dual mode terminal 500 Reject the access request (step 581).
