Abstract

The invention discloses a method, a corresponding device and a system for establishing local exchange. The method comprises the following steps: using a second mobile exchange center to receive information sent by a first mobile exchange center, wherein the information contains a calling branch identification controlled by the first mobile exchange center and an identification of a controller requiring for establishing local exchange; judging whether meeting the conditions of establishing local exchange by the second mobile exchange center; and when the conditions of establishing local exchange are met, using the second mobile exchange center to inform the controller to establish local exchange according to the calling branch identification controlled by the first mobile exchange center. By using the method, device and system for establishing local exchange provided by the invention, the application scene of the local exchange is expanded and the success rate for establishing local exchange is increased.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method, device and system for establishing a local exchange. Background technique [0002] In a local call, for a scenario where multiple MSCs (Mobile Switching Centers) are involved in the call, such as in the GSM system, the BSC (Base Station Controller) is simultaneously connected to MSC1 and MSC2. The call branch of calling MS1 (mobile station) is controlled by MSC1, and the call branch of called MS2 is controlled by MSC2. If MSC1 finds that local switching can be established, MSC1 notifies BSC directly. After receiving the notification, the BSC executes the local switching operation. If the BSC completes the local exchange successfully, it will notify MSC1 through a message. After receiving the message, MSC1 informs MSC2 that the local switching has been established, and MSC-2 responds after receiving the message. [0003] In the prior art, there is such a situation that w...
