Method, device and system for establishing local exchange

Abstract

The embodiment of the invention discloses a method, a device and a system for establishing local exchange, which relate to the field of communication and aim to solve the problems that the local exchange of a call pair in a BSS (Base Station Subsystem) can not be established in time by a MSC (Mobile Switching Center) and calls for establishing the local exchange are likely to be not controlled by the MSC due to the local exchange established through a BSC (Base Station Controller). The technical scheme provided by the invention comprises the following steps of: sending a local exchange request message to a mobile switching center; and receiving a local exchange establishing message returned by the mobile switching center and establishing the local exchange according to the local exchange establishing message. The technical scheme provided by the embodiment of the invention can be applied to communication systems such as WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), LTE (Long Term Evolution) and the like.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for establishing a local exchange. Background technique [0002] In order to save communication resources and reduce network construction and operation costs, in the prior art, if the calling parties constituting the session are located in the same Base Station Subsystem (BSS), local switching can be established for the calling parties, The calling parties are made to communicate through local switching. [0003] Currently, existing technologies can provide two methods for establishing local switching: [0004] One is that a base station controller (Base Station Controller, BSC) in the BSS judges whether the calling parties constituting the session can establish local switching, and if local switching can be established, the BSC establishes local switching for the calling parties. [0005] In the process of realizing the present invention, the inven...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the method at least has the following problems: the mobile switching center (Mobile Switch Center, MSC) cannot know for which calls the BSC has established a local exchange, so that it is impossible to establish a local exchange for both callers. control

[0007] In the process of implementing the present invention, the inventors found that this method has at least the following problems: MSC cannot know the transmission resource occupancy of the BSS side, and when the transmission resources of the BSS side are in short supply, the MSC cannot find out in time and notify the BSS to establish local switching
