Method and device for establishing session based on location information in ONLY service

Abstract

The invention proposes a method and device for establishing a session in a service server of a communication system based on fixed and mobile network fusion technology. After receiving the call request from the calling user terminal, the service server first obtains the location information of the mobile terminal associated with the called number according to the called number in the call request, and then obtains the location information of the mobile terminal according to the obtained location information of the mobile terminal. information and the location information of one or more fixed terminals associated with the called number, and determine whether the minimum distance difference among the one or more distance differences between the one or more fixed terminals and the mobile terminal is less than A first threshold; if yes, routing the call request to the fixed terminal corresponding to the minimum distance difference. Since the service server directly routes the call request to the fixed terminal, wireless air resources are effectively saved. In addition, it can also effectively reduce the call establishment delay and improve the success rate of call establishment.

Description

technical field [0001] The present invention relates to a communication system, in particular to a one number service (onenumber service) in a communication system based on fixed and mobile convergence (FMC) technology. Background technique [0002] With the rapid development of mobile technology and IP technology, fixed and mobile convergence (fixed and mobile convergence, FMC) has become a very hot field for telecom operators and suppliers. FMC means that the service provision of the network is independent of the access technology and terminal equipment. From the perspective of users, the purpose of FMC is to enable users to enjoy the same service and obtain the same business through different access networks. Its main feature is that the service subscribed by the user has nothing to do with the access point and the terminal, that is, it allows the user to use the same service from a fixed or mobile terminal through any suitable access point. FMC can enable users to use ...

Problems solved by technology

[0008] The use of parallel routing can save call setup time, but the requirements for network entities that implement call forking will become higher

In addition, when multiple user terminals associated with the called number answer the call request of the calling party almost simultaneously, the parallel routing method will also introduce a race condition, but in the end only one called user terminal can communicate with the calling party. Establish a session connection, and the calling party's calls to other called user terminals will be released by the network side
