Method, apparatus and system for establishing communication

Abstract

The embodiment of the invention discloses a method, a device and a system for establishing communication and aims to solve the problem that communication parties can not communicate normally when local communication establishment fails. The invention adopts a technical proposal that a first base transceiver station and a second transceiver station establish local communication IWF lists in a reception direction first and then establish local communication IWF lists in a transmission direction after the local communication IWF lists in the reception direction are established successively; and if the local communication IWF lists in the transmission direction of the first base transceiver station and / or the second base transceiver station are established successfully, local communication with opposite ends is started by using the local communication IWF lists in the transmission direction, and communication with the opposite ends is established according to the responses of the IWF lists in the reception direction. In the embodiment, the technical proposal provided by the invention can be used in wireless communication systems such as an IP-based GSM system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for establishing communication. Background technique [0002] In order to reduce the network operation cost, the GSM network has been gradually developed to IP. After the GSM network is IP-based, the base station (Base Transceiver Station, BTS) has a network interworking function (Interworking Function, IWF), and the BTS can communicate according to the pre-stored IWF table. [0003] Generally, the IWF table of the traditional communication method is pre-stored on the BTS, and the BTSs of the two communication parties can pass the base station controller (Base Station Controller, BSC) according to the IWF table of the traditional communication method, via the core network (Core Network, CN) to establish a connection and communicate. [0004] In order to save communication resources, when the BTSs of both communication parties belong to the same BSC,...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: when one of the BTSs of the communicating parties fails to establish the local communication IWF table, while the other party’s local communication IWF table is successfully established, the BTSs of the communicating parties The stored IWF table is inconsistent, so that the communication parties cannot establish a connection, which leads to the inability of the communication parties to communicate, and the original communication is interrupted
