Step 1: in the signaling catching gateway stores 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, this signaling catching gateway is tackled described " position updating request " message, and parses VLR number and terminal IMSI in " position updating request " message;
Step 3: the signaling catching gateway compares with VLR that sets in advance in the gateway and dominance relation according to the VLR number of intercepting and capturing that arrives, and carries out the prioritization logic computing:
For qualified location update request message, the direct transparent transmission of gateway is somebody's turn to do " position updating request " to the HLR that belongs to state, carries out normal location update operations;
For ineligible location update request message, after gateway was was directly intercepted and captured, the HLR to ownership state did not send this message, but replied " failure is upgraded in the position " response message to the MSC/VLR of roaming country, made user's registered network fail; Thereby allow the terminal use initiate register requirement again, calculate condition by the prioritization logic at signaling catching gateway place up to the VLR number of user's registration.
In step 3, so-called prioritization logic computing, can do as judging at the signaling catching gateway:
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 signaling catching gateway of Location Registration, this signaling catching gateway 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 is deleted all information of the IMSI correspondence on the gateway simultaneously to the HLR of ownership state.
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 signaling catching gateway, can be this position updating request of direct transparent transmission according to switch control, still refuse this position updating request.
The function of this signaling catching gateway can and international signalling transfer point (ISTP) unification, do not need to be provided with separate equipment and network element.
The function of this signaling catching gateway can be unified with HLR, and this function is set on HLR, just can control this HLR and preferably register MSC/VLR when upward the user roams.

Step 305: the signaling catching gateway, this position updating request of transparent transmission is to international signalling transfer point;
Step 306: international signalling transfer point forwards the message to user's attaching position register (HLR);
Step 307: attaching position register sends and inserts user data requests to international signalling transfer point;
Step 308: international signalling transfer point forwards the request to the signaling catching gateway;
Step 309: this asks the international inlet and outlet bureau of roaming country the signaling catching gateway forwards;
Step 310: international inlet and outlet bureau transmits and inserts the MSC/VLR of user data requests to roaming country;
Step 311: roaming country MSC/VLR preserves user data, sends to international inlet and outlet bureau and inserts the user data response;
Step 312: international inlet and outlet bureau sends to the signaling catching gateway and inserts the user data response;
Step 313: the signaling catching gateway sends to international signalling transfer point and inserts the user data response;
Step 314: international signalling transfer point sends to attaching position register and inserts the user data response;
Step 315: attaching position register is finished the preservation of customer position information, sends the position to international signalling transfer point and upgrades response;
Step 316: international signalling transfer point sends the position to the signaling catching gateway and upgrades response;
Step 317: the signaling catching gateway sends position renewal response to the international inlet and outlet bureau of roaming country;
Step 318: the international inlet and outlet bureau of roaming country sends the position to roaming country MSC/VLR and upgrades response;
Step 319:MSC/VLR completing place is upgraded, user registration success;
Step 320: the signaling catching gateway sends position renewal failure response to the international inlet and outlet bureau of roaming country;
Step 321: roaming country international inlet and outlet bureau sends the position to roaming place MSC/VLR and upgrades failure response;
Failure, user's registration failure are upgraded in step 322:MSC/VLR position.
