Description

Method and system for implementing flexible ringing service

Technical field

The present invention relates to the field of communications, and in particular, to a method and system for implementing a flexible ringing service. Background technique

Currently, the flexible alert (FA) service has been adopted in the field of communications. The so-called FA service means that the user dials a number, one or more terminals ring at the same time, the number dialed by the user is the pilot number, and the ringing terminal is the member of the FA group corresponding to the pilot number. In the FA service, when the user dials the pilot number, the call will be connected to all members, and all members will ring at the same time. When one of them picks up the call, the caller will establish a call with this member, and the rest of the call branches will be released. Drop it.

An implementation architecture of a typical flexible ringing service is shown in FIG. 1. A User Equipment (UE) 101, 107 is a user terminal, and represents a member of the calling party or the FA. Base station and base station controllers (BTS/BSC) 102, 106 are used to implement wireless transceiver and resource management, and realize communication connection between users and switching centers. Mobile switching center/visiting location register (MSC/VLR, Mobile Switched) Center/Visited Location Register 103, 105 is a control center for implementing call control and service implementation. The VLR stores all visited mobile user information in its control area, and the information includes management data of the MSC for call control and service realization. The home location register (HLR) 104 contains information about the mobile user controlled by the HLR, such as basic information when the user opens an account, and the like.

The following describes the execution process of the flexible ringing in the prior art. Assume that the FA group consists of three members: one is a fixed telephone number DN1 ( Directory number 1); the other two members are mobile stations (MS) belonging to the same HLR and currently served by the same serving MSC (T_MSC), number For MINI (mobile identity number 1) and MIN2. The process is shown in Figure 2:

201. The calling party initiates a call, dials the pilot number of the FA group, and the originating MSC (0-MSC) receives the originating call and the pilot number of the FA group;

202. The originating MSC sends a location request to the HLR associated with the pilot number; 203 ~ 206. After receiving the location request, the HLR finds that the called number is a FA pilot number; the HLR confirms that the originating MSC can support one FA call according to the received processing capability parameter, and the HLR sends two routing requests to the serving VLR respectively. , respectively, for the MINI and MIN2, the VLR respectively delivers the two routing requests to the serving MSC;

207 - 210. In response to the routing request, the serving MSC verifies its internal data structure and determines that the mobile station is currently idle, and then assigns a TLDN (temporary location directory number) to each of the two routing requests. One is TLDN1, one is TLDN2, and returns information to the VLR in the routing request response, and the VLR sends two routing request responses to the HLR respectively;

211. When the HLR receives all the routing request responses, it returns a location request response to the originating MSC; the location request response includes a plurality of terminal routing selection information described in the form of terminal list parameters;

212. After receiving the location request response, the originating MSC may begin providing call confirmation information to the calling party;

213. The originating MSC attempts to establish a call to DN1 at the same time according to the indication in the location request response;

214. Perform step 213 while establishing a call to TLDN1;

215. Proceed to step 213 to establish a call to TLDN2;

213-215 These calls can be outgoing calls or internal calls. For each call attempt, the originating MSC monitors the establishment of the call;

216. TLDN1 response; originating MSC connection caller and TLDN1;

217. Release the call to DN1 while performing step 216;

218. Release the call to TLDN2 while performing step 216.

However, when the members are prepaid users, the existing process cannot be processed. In the existing process, when the HLR finds that the MINI is a mobile user, it will initiate a routing request to obtain the TLDN. The prepaid user is generally unable to initiate the acquisition of the TLDN before acquiring the trigger. Therefore, the existing process cannot trigger the normal processing of the prepaid user.
