 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a schematic structural diagram of a system corresponding to an embodiment of the present invention, taking a GSM (Global System of Mobile communication) network and a TD-SCDMA network as an example. Of course, it can also be a GSM network and other Universal Mobile Telecommunications System (UMTS), for example, a Wideband Code Division Multiple Access (WCDMA) network, or a GSM network and long-term evolution ( Long Term Evolution, LTE) network. For the GSM network, the corresponding network control node is a Base Station Controller (BSC); for the UMTS network, the corresponding network control node is a Radio Network Controller (RNC), and the corresponding CS domain core. The node of the network is a Mobile Switch Center (MSC); for the LTE network, the corresponding network control node is an evolved base station (eNB), and the node of the corresponding CS domain core network is a Mobile Management Entity (MME). . In this embodiment, a single card dual standby terminal 11, a base station (NodeB) 12, a base transceiver station (Base Transceiver Station, BTS) 13, a radio network controller (RNC) 14, and a base station controller (Base Station Controller) are included. , BSC) 15. Serving a General Packet Radio Service (GPRS) Supporting Station (SGSN) 16 and a Mobile Switch Center (MSC) 17. The RNC 14 communicates with the BSC 15 through a new interface (such as the inter-controller interface Iur-g). The RNC and the BSC implement the adaptation functions of the A interface and the Iu-cs interface on the Iur-g interface. The MSC is a device in a Circuit Switched (CS) domain, and the SGSN is a device in a Packet Switched (PS) domain.

 In this embodiment, the RNC and the BSC are separately set as an example. It can be understood that a dual mode controller can be used instead of the RNC and the BSC. The dual mode controller has the functions of the RNC and the BSC, and the inter-controller interface acts as a dual mode. Controller internal interface.

Under the system architecture, a single-card dual-standby terminal is simultaneously attached to GSM and TD-SCDMA, and implements a dual-mode dual-standby mechanism, which can perform different services in different networks at the same time, and the dual-stack stack shares different tasks, for example, link 1 As shown, the data traffic is carried in the TD-SCDMA system; as shown in link 2, the voice traffic is carried in the GSM system. The MSC communicates with the BSC through the RNC, so that the CS domain is unified with the Iu-cs interface relative to the core network; and is connected to the Iur-g interface or the dual-mode controller. The control plane and user plane are processed on the mouth.

 In order to achieve the simultaneous standby of the above GSM and TD-SCDMA networks, registration in both networks is first required.

 2 is a schematic flow chart of a method according to a first embodiment of the present invention, including:

 Step 21: The second network control device receives, by the first network control device, a message that carries the location area information of the single card dual standby terminal in the 2G network.

 For example, referring to the system of Fig. 1, the second network control device is an RNC, and the first network control device is a BSC. When the single-card dual-standby terminal initiates registration in the GSM network, the location area information is the location area information of the 2G system, which is assumed to be LAI-2.

 Step 22: The second network control device converts the location area information in the 2G network into location area information in the 3G network, and sends a location area update request message to the circuit switched CS domain of the 3G network to implement the single card. The dual standby terminal updates the registration in the location area in the 3G network.

 The RNC may convert the location area information in the 2G network into location area information in the 3G network according to a pre-configured correspondence.

 For example, the terminal initiates registration in the GSM network. At this time, the terminal first sends a location area update request message to the BSC, where the terminal class is carried. If the terminal category indicates that the terminal is a single card dual standby terminal, the BSC locates the location area. The update request message is sent to the RNC (eg via the Iur-g interface), which carries LAI-1. After receiving the location area update request message from the BSC, the RNC converts the LAI-1 into the location area information under the TD-SCDMA system according to the pre-configured correspondence, which is assumed to be LAI-3. Thereafter, the RNC transmits a location area update request message carrying LAI-3 to the core network under 3G corresponding to TD-SCDMA. In the subsequent registration process, the signaling between the terminal and the core network is forwarded through the BSC and the RNC, and finally the location area update registration is implemented.

 Further, the embodiment may further include the step of authenticating, because the authentication quintuple is used in the 3G network, and the authentication triplet is used in the 2G network, the second network control device may perform the authentication quintuple. And the conversion of the authentication triplet, which may also include:

Receiving, by the second network control device, the authentication of the carrying authentication quintuple sent by the CS domain a message, converting the authentication quintuple into an authentication triplet, and carrying the authentication triplet in an authentication message sent to the first network control device;

 The second network control device receives an authentication message carrying the authentication triplet sent by the first network control device, converts the authentication triplet into an authentication quintuple, and performs the authentication. The quintuple is carried in an authentication message sent to the CS domain.

 The second network control device may save the correspondence between the authentication quintuple and the authentication triplet, and perform the foregoing conversion according to the corresponding relationship.

 In this embodiment, the user can pass the 2G by converting the location area information in the 2G network into the location area information in the 3G network, and sending the location area update request message initiated by the terminal in the 2G network to the 3G network for registration. The access network opens and registers with the 3G core network.

 FIG. 3 is a schematic flowchart of a method according to a second embodiment of the present invention, including:

 Step 31: The first network control device receives a message carrying the terminal category sent by the terminal in the 2G network.

 The message may carry the information of the terminal when the terminal sends the message to the first network control device, for example, the class-1 or classmark-2 of the terminal is carried, and then the class label can be used. The idle bit of -1 or class-2 carries the terminal type.

 Step 32: When it is determined that the terminal is a single-card dual-standby terminal according to the terminal category, the first network control device sends a location area update request message to the second network control device, where the location area update request message is Carrying location area information of the terminal in the 2G network, so that the second network control device converts the location area information in the 2G network into location area information in the 3G network and sends the circuit switching to the 3G network The domain is configured to implement location area update registration of the terminal in the 3G network.

Further, the embodiment may further include the step of authenticating, because the authentication quintuple is used in the 3G network, and the authentication triplet is used in the 2G network, therefore, different from the first embodiment, this embodiment The conversion of the authentication quintuple and the authentication triplet by the first network control device may also include: Receiving, by the first network control device, the authentication of the carrying authentication quintuple sent by the second network control device, converting the authentication quintuple into an authentication triplet, and the authenticating three The tuple is carried in an authentication message sent to the terminal;

 The first network control device receives an authentication message carrying the authentication triplet sent by the terminal, converts the authentication triplet into an authentication quintuple, and carries the authentication quintuple In an authentication message sent to the second network control device.

 The second network control device may save the correspondence between the authentication quintuple and the authentication triplet, and perform the foregoing conversion according to the corresponding relationship.

 In this embodiment, the user can pass the 2G by converting the location area information in the 2G network into the location area information in the 3G network, and sending the location area update request message initiated by the terminal in the 2G network to the 3G network for registration. The access network opens and registers with the 3G core network.

 FIG. 4 is a schematic flowchart of a method according to a third embodiment of the present invention. In this embodiment, a terminal performs a location area update registration of a CS domain as an example. Referring to FIG. 4, this embodiment includes:

 Step 401: The terminal sends a location area update request message to the BSC, where the terminal class and the LAI-2 are carried.

 The terminal class may specifically use the idle bit of the class label -1 or the class label -2 (Classmark 1 or Classmark 2) to indicate whether the corresponding terminal is a single card dual standby terminal.

 The composition of the class -1 can be as shown in Table 1, including two bytes, where the eighth bit of the second byte is the spare. In this case, the idle terminal can be used to indicate that the corresponding terminal is a single-card dual-standby terminal. For example, when the idle bit =0 is set, the corresponding terminal is a single-card dual-standby terminal.

 Table 1

The composition of the class-2 can be as shown in Table 2. The class-2 includes 5 bytes, and the 8th bit of the 3rd byte is an idle bit, similar to the class-1, which can be used by the idle bit. Indicate that the corresponding terminal is Single card dual standby terminal.

Table 2

Step 402: When the BSC determines that the terminal is a single-card dual-standby terminal according to the terminal category, the BSC sends a location area update request message to the RNC, where the LAI-2 and the terminal identifier are carried.

 If the 8th bit of the second byte of the class-1 is indicated as a single card dual standby terminal, the terminal is determined to be a single card dual standby terminal.

 Then, when it is determined that the terminal is a single card dual standby terminal, it can be sent to the RNC through the Iur-g interface.

 Step 403: The RNC converts the location area information on the 2G side into the location area information on the 3G side, for example, converting LAI-2 to LAI-3.

 The mapping table may be pre-stored in the RNC, and the mapping table indicates the correspondence between the location area information on the 2G side and the location area information on the 3G side. By using the mapping table, the LAI-2 can be converted to the LAI-3.

 Step 404: The RNC sends a location area update request message to the MSC in the 3G core network, where the LAI-3 and the terminal identifier are carried.

After receiving the location area update request message, the MSC on the 3G side may save the LAI-3 and the terminal identifier in a Home Location Register (HLR). Step 405: The MSC sends a location area update response message to the terminal through the RNC and the BSC to complete the location area update registration of the terminal in the CS domain.

 Further, if authentication is required, since the authentication parameter of the 3G is the authentication quintuple and the authentication parameter of the 2G is the authentication triplet, after the MSC initiates the authentication, the RNC needs to authenticate the quintuple. The group is converted into an authentication triplet, and the authentication triplet is sent to the BSC. At this time, the correspondence between the authentication quintuple and the authentication triplet can be pre-configured in the RNC. Of course, the correspondence between the authentication quintuple and the authentication triplet may be pre-configured in the BSC, and the BSC performs the conversion between the authentication quintuple and the authentication triplet. Alternatively, the correspondence between the authentication quintuple and the authentication triplet may be pre-configured in the UE, and the UE performs the conversion of the authentication quintuple and the authentication triplet.

 Correspondingly, the authentication triplet needs to be converted into an authentication quintuple on the UE side.

 After the BSC determines that the single-card dual-standby terminal initiates the registration, the BSC sends the relevant signaling to the RNC, and the RNC forwards the registration to the 3G MSC, so that the terminal can initiate registration in the 2G and register in the 3G. The 2G access network opens an account and registers with the 3G core network.

 FIG. 5 is a schematic flowchart of a method according to a fourth embodiment of the present invention. In this embodiment, a terminal performs a location area update registration in a PS domain, and a suitable TD-SCDMA cell exists as an example. Referring to Figure 5, this embodiment includes:

 Step 501: If a suitable TD-SCDMA cell exists, the terminal sends a location area update request message to the RNC, where the LAI-1 and the terminal identifier are carried.

 The terminal may determine whether a suitable TD-SCDMA cell exists according to a preset condition. For example, whether the signal quality of the detected TD-SCDMA cell satisfies a preset quality requirement may be used to determine whether there is a suitable one. TD-SCDMA cell.

 Step 502: The RNC sends the location area update request message to the SGSN in the 3G through the Iu-PS interface, where the LAI-1 and the terminal identifier are carried.

 After receiving the location area update request message, the SGSN may store the LAI-1 and the terminal identifier in the location area update request message in the HLR.

Step 503: The SGSN sends a location area update response message to the terminal through the RNC to complete The terminal is registered for registration in the PS domain.

 In this embodiment, the interaction between the terminal and the RNC, and the interaction between the RNC and the SGSN can directly complete the registration of the PS domain in the 3G.

 FIG. 6 is a schematic flowchart of a method according to a fifth embodiment of the present invention. In this embodiment, a terminal performs a location area update registration in a PS domain, and there is no suitable TD-SCDMA cell as an example. Referring to FIG. 5, this embodiment includes:

 Step 601: If there is no suitable TD-SCDMA cell, the terminal sends a routing area update request message or an attach request message to the BSC, where the LAI-2 and the terminal identifier are carried.

 The terminal may determine whether a suitable TD-SCDMA cell exists according to a preset condition. For example, whether the signal quality of the detected TD-SCDMA cell satisfies a preset quality requirement may be used to determine whether there is a suitable one. TD-SCDMA cell.

 Step 602: The BSC sends the routing area update request message or the attach request message to the SGSN in the 2G through the Gb interface, where the LAI-2 and the terminal identifier are carried.

 The Gb interface is an interface between the BSC and the SGSN.

 After receiving the location area update request message, the SGSN may store the LAI-1 and the terminal identifier in the location area update request message in the HLR.

 Step 603: The SGSN sends a location area update response message to the terminal through the BSC to complete the update registration of the terminal in the PS domain.

 In this embodiment, the interaction between the terminal and the BSC, and the interaction between the BSC and the SGSN can be completed in the PS domain of the 3G through 2G.

In the embodiment of the present invention, when the terminal is in the GSM network, the location update request message may be sent to the MSC in the 3G through the processing of the BSC and the RNC, so that the terminal is registered in the CS domain of the 3G, so that the voice service (CS domain service) ) carried by the GSM network. When the terminal is in the TD-SCDAM network, the RNC is registered to the PS domain of the 3G, and the data service (PS domain service) can be carried by the TD-SCDMA. Through the above registration in the CS domain and the PS domain, the terminal can be attached at the same time in GSM and TD-SCDMA, and the voice service is carried by GSM, and the data service is TD-SCDMA bearer realizes the convergence of 2/3G networks and utilizes the advantages of 2/3G networks respectively. When registering in the PS domain, whether it is initiated at 2G or initiated at 3G, it is registered in the PS domain of 3G, which can reduce the PS reselection interrupt. In the above registration process, whether it is initiated by 2G or initiated by 3G, it is registered to the corresponding 3G CS domain or PS domain, and the dual network attachment details are shielded from the core network. The core network considers that the terminal is attached in 3G, so It can carry out 3G special services, such as video phone (VP) service. For a single card, for the HLR, regardless of the 2G or 3G registration, the corresponding identification information of the single-card terminal is not required, and the identification information of the terminals in the two networks is not required, and the dual-network attachment can be supported without HLR modification.
