Step 1: in database 22 storages the number information of the VLR of preferred roaming country mobile operator need be set, and the priority level of each VLR is set according to the preference relation that the mobile operator that belongs to state and roaming country consults in advance;
Step 2: the user of ownership state roams into when external, the terminal use registers online in roaming country, the MSC/VLR of roaming country sends " position updating request " of user's registration to the HLR of ownership state, the signaling catching front end processor of this international signalling transfer point is tackled described " position updating request " message, and parses VLR number and terminal IMSI in " position updating request " message;
Step 3: the VLR number that arrives according to intercepting and capturing, compare with VLR that sets in advance and dominance relation, carry out the prioritization logic computing:
For qualified location update request message, directly transparent transmission is somebody's turn to do " position updating request " to signal switching basic module 20, and is dealt into the HLR of ownership state, carries out normal location update operations;
For ineligible location update request message, the HLR to ownership state does not send this message, but replys " failure is upgraded in the position " response message to the MSC/VLR of roaming country, makes user's registered network fail; Thereby allow the terminal use initiate register requirement again, up to the VLR number of user registration prioritization logic calculation condition by the international signalling transfer point place.
In step 3, so-called prioritization logic computing, can do as judging at the signaling process front end processor:
Other according to different priorities, the continuous times of registration of interception user is set, the VLR group interception number of times of high priority is few, and the VLR group interception of low priority is often.
When the user carries out " position updating request " message process international signalling transfer point of Location Registration, this signaling process front end processor is analyzed the VLR number in " position updating request " message, write down this user's IMSI and VLR and continuous times of registration, when if current this user's continuous times of registration meets or exceeds the continuous times of registration of the permission user of this VLR place group, then directly this position updating request of transparent transmission arrives the HLR that belongs to state, simultaneously all information of the IMSI correspondence on the delete database 22.
That is to say behind terminal use's registration failure, user's continuous several times again is registered to not preferred VLR, do not influence the user uses in order to allow the user to insert, set " times of registration continuously " here, that is: when times of registration surpasses the continuous times of registration of predefined permission, just allow the user to register by not preferred VLR.
If the VLR number of interception is not configuration in the database of international signalling transfer point, can be this position updating request of direct transparent transmission according to switch control, still refuse this position updating request.
Fig. 3 is based on system shown in Figure 1, utilizes international signalling transfer point to realize user's register flow path figure of control international visit user to log into preferred operator network method.Concrete steps are as follows:
Step 301: the user is registered to the mobile network of roaming country in the roaming place;
Step 302: mobile switching centre sends location update request message to international inlet and outlet bureau;
Step 303: international inlet and outlet bureau is transmitted to international signalling transfer point with position updating request;
Step 304: international signalling transfer point, the VLR number in the capture condition update request carries out preferred analyzing and processing, analyzes by entering step 305, analyzes not by entering step 316;
Step 305: international signalling transfer point forwards the message to user's attaching position register (HLR);
Step 306: attaching position register sends and inserts user data requests to international signalling transfer point;
Step 307: international signalling transfer point forwards the request to the international inlet and outlet bureau of roaming country;
Step 308: international inlet and outlet bureau transmits and inserts the MSC/VLR of user data requests to roaming country;
Step 309: roaming country MSC/VLR preserves user data, sends to international inlet and outlet bureau and inserts the user data response;
Step 310: international inlet and outlet bureau sends to international signalling transfer point and inserts the user data response;
Step 311: international signalling transfer point sends to attaching position register and inserts the user data response;
Step 312: attaching position register is finished the preservation of customer position information, sends the position to international signalling transfer point and upgrades response;
