Position information-based session establishing method and device in one number service

Abstract

The invention discloses a session establishing method and a session establishing device in a service server of a fixed and mobile network fusion technology-based communication system. The method comprises the following steps of: after the service server receives a call request from a calling user terminal, acquiring the position information of a mobile terminal related to a called number according to the called number in the call request and determining whether a minimum distance difference value in one or more distance difference values between one or more fixed terminals and mobile terminals is less than a first threshold value or not according to the acquired position information of the mobile terminal and the position information of the one or more fixed terminals related to the called number; and if the minimum distance difference value is less than the first threshold value, routing the call request to a fixed terminal corresponding to the minimum distance difference value. The service server directly routes the call request to the fixed terminal, so that radio air resource is saved effectively. Moreover, time delay of call establishment can be reduced effectively and the success rate of call establishment is increased.

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
