Step 203, ownership HLR exhales MSC to send the mobile terminal request response to the beginning;
Step 204, the beginning exhales MSC/VLR to send the initialization terminal analysis request to ownership SCP (service control point);
Step 205, ownership SCP exhales MSC/VLR to send initialization terminal analysis request response message to the beginning, carries called subscriber's service key sign in the response message;
Step 206, the beginning exhales MSC/VLR to send senior terminal analysis request to ownership SCP;
Step 207, ownership SCP exhales MSC/VLR to send senior terminal analysis request response to the beginning; Carry called mobile station characteristic ringing code in the response message;
Step 208, the beginning exhales MSC/VLR to send location request message to ownership HLR, carries called mobile station characteristic ringing code in the message;
Step 209, ownership HLR sends route request information to service MSC/VLR, carries called mobile station characteristic ringing code in the message;
Step 210, service MSC/VLR initiates inter-system paging ISPAGE request message and gives edge MSC/VLR, carries called mobile station characteristic ringing code in the message; Edge MSC/VLR keeps in user's characteristic ringing code;
Step 211, paging ISPAGE response message between edge MSC/VLR retrieval system carries the interim roaming number of called mobile station in the message;
Step 212, service MSC/VLR sends the route requests response message to ownership HLR, carries the interim roaming number of called mobile station in the message;
Step 213, ownership HLR exhales MSC/VLR to send position request response message to the beginning; Carry the interim roaming number of called mobile station in the message;
Step 214, the beginning exhales MSC/VLR to send called routing address efficiency analysis request message to ownership SCP, carries the interim roaming number of called mobile station in the message;
Step 215, ownership SCP exhales MSC/VLR to send called routing address efficiency analysis response message to the beginning;
Step 216, the beginning exhales MSC/VLR to initiate the forward direction setup requests to edge MSC/VLR;
Step 217, edge MSC/VLR obtains called mobile station characteristic ringing code, initiates the wireless channel assignment request message to ownership SCP then, carries called mobile station characteristic ringing code in the message.
There is following shortcoming in the scheme that in above-mentioned ISPAGE process, realizes characteristic ring advice of charge:
1, parameter A LRTCODE exhales MSC/VLR to know that the definite position of called MS issues before by SCP in the beginning; When MS roams in the service overlapping region of two MSC/VLR; SCP can't learn the definite position of called MS in real time, and may cause the ALRTCODE that issues inaccurate this moment, and ALRTCODE is being temporary in before BSS further issues among the edge MSC/VLR; Have no chance to be updated, finally can cause the called subscriber possibly hear incorrect ringring prompting sound;
2, ALRTCODE is as the optional parameters of IS-41D and IS-848 agreement regulation; Entrained by LOCREQ (position requests), ROUTREQ (route requests), ISPAGE request message in existing implementation; In the call flow process, need the repeatedly operation of Code And Decode; Increase the time overhead of system, caused efficient to reduce.
