Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of implementation method and system of bimodule service.
Background technology
Bimodule service refers to that the user uses dual-mode terminal, freely switches use between the mobile communication network of two kinds of different systems.Bimodule service can be divided into single standby mode and many standby modes according to whether being in simultaneously holding state two mobile communication system simultaneously; According to whether using identical number two mobile communication system, can be divided into odd numbers mode and manys' mode.
Bimodule service herein refers to the bimodule service of single standby, odd numbers mode, be that the user uses single number, be single MSISDN (Mobile Station Integrated Services Digital Number, portable terminal integrated service digital coding), all determine to login which network by the user in the overlayable situation at two mobile communication system networks (abbreviation network); In the situation that a network coverage is only arranged, sign in to this network, and the business such as user's voice, note are not affected.
The mobile communcations system of bimodule service can be any two kinds in the following system: PCS (PersonalCommunications Service, personal communication service) system, GSM (Global System for Mobilecommunication, global system for mobile communications), CDMA (Code Division Multiple Access, code division multiple access) system, TD-SCDMA (Time Division-Synchronous CDMA, TD SDMA) system, WCDMA (Wide Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) system, CDMA 2000 systems etc.
Fig. 1 is the schematic network structure that realizes bimodule service in the prior art by protocol conversion gateway.As shown in Figure 1, existing bimodule service adopts the implementation method of protocol conversion usually, namely realizes bimodule service by between two mobile communication system protocol conversion gateway being set.Protocol conversion gateway, for example, the effect of CDMA-GSM gateway/GSM-CDMA gateway is the protocol conversion of carrying out CDMA and GSM between cdma network and GSM network for the user.
According to existing bimodule service implementation method, dual-mode subscriber is in two mobile communication system signatory (namely only distributing telephone numbers at a network) only, and this network is called as the subscription network of dual-mode subscriber, or master network; Another network is called as secondary network.
For dual-mode subscriber at the HLR of master network (Home Location Register, attaching position register) distributes telephone numbers after (namely in HLR network element entity, depositing the information such as user's signing service data), set up the incidence relation of IMSI (International Mobile Subscriber Identity, the IMSI International Mobile Subscriber Identity) number of two networks of this user at protocol conversion gateway.The user is when master network, and business processing flow is identical with common master network operation flow, and all business all need not through protocol conversion gateway; When the user roams into secondary network, just must be finished by protocol conversion gateway the conversion of two kinds of procotols, thereby realize the mutual and transmission of customer position information.
For example, when the user when secondary network carries out location register, the position register request of secondary network is sent to protocol conversion gateway, protocol conversion gateway enquiry number incidence relation, and convert position register request to the master network related news, utilize the IMSI of master network to the enterprising line position registration of the HLR of master network, in order to preserve user's positional information at HLR.

Step 202: protocol conversion gateway Query Database, find this user's master network IMSI, the position register request that receives is converted to the position register request of the first mobile communcations system agreement, and use this user's master network IMSI, to the HLR launch position registration request of the first mobile communcations system;
Step 203: the HLR of the first mobile communcations system determines to allow user's roaming, sends the insertion user data requests, and this request is addressed to protocol conversion gateway;
Step 204: protocol conversion gateway is according to the business information that comprises in the insertion user data requests that receives, the related service that finds the second mobile communcations system to support, generate the insertion user data requests of the second mobile communcations system agreement, and this request is issued the VLR of the second mobile communcations system;
Attention: when the insertion user data requests according to the first mobile communcations system generates the second mobile communcations system insertion user data requests, may occur because the second mobile communcations system (secondary network) is not supported the situation that the user is dropped in the signatory business information of the first mobile communcations system (master network).
Step 205: the VLR of the second mobile communcations system returns to protocol conversion gateway and inserts the user data response;
Step 206: protocol conversion gateway carries out the response of the insertion user data that receives to send to after the protocol conversion HLR of the first mobile communcations system;
Step 207: it is complete that the HLR of the first mobile communcations system finds that user data inserts, to protocol conversion gateway home position register response;
Step 208: protocol conversion gateway carries out the response of the location register that receives to send to after the protocol conversion VLR of the second mobile communcations system.
Fig. 3 is the method for calling flow chart that the available technology adopting protocol conversion technology realizes.The supposition calling subscriber is the user of the first mobile communcations system in this flow process; The called subscriber is dual-mode subscriber, and called subscriber's master network is the first mobile communcations system, but the called subscriber turns net to the second mobile communcations system (secondary network) by the first mobile communcations system at present.As shown in Figure 3, corresponding call flow comprises the steps:
Step 301: the MSC of the first mobile communcations system (Mobile Switch Center, mobile switching centre) receives the initialization address message (Initial Address Message is called for short IAM) that the calling subscriber sends;
Step 302: the MSC of the first mobile communcations system adopts MAP (Mobile Application Part, the MAP) signaling of the first mobile communcations system to the HLR transmission routing inquiry request of the first mobile communcations system;
Step 303: the HLR of the first mobile communcations system adopts the MAP signaling of the first mobile communcations system to protocol conversion gateway request roaming number;
Step 304: protocol conversion gateway adopts the MAP signaling of the second mobile communcations system to the VLR transmission route information query request of the second mobile communcations system, with inquiry called subscriber's routing iinformation;
Step 305: the VLR of the second mobile communcations system adopts the MAP signaling of the second mobile communcations system to return called subscriber's routing iinformation (wherein comprising roaming number) to protocol conversion gateway;
Step 306: after receiving called subscriber's routing iinformation, protocol conversion gateway carries out protocol conversion to it, with the second mobile communcations system routing iinformation be converted to the routing iinformation of the first mobile communcations system, and send to the HLR of the first mobile communcations system;
Step 307: the HLR of the first mobile communcations system is included in the MSC that sends to the first mobile communcations system in the route information query response with called subscriber's routing iinformation;
Carry out follow-up call proceeding behind the MSC acquisition called subscriber's of the first mobile communcations system the routing iinformation.
