Embodiment Construction

[0027] In the event of geological disasters, the ground transmission link may be damaged, and the ground transmission link cannot be used to transmit signals between the base station and the base station controller, and no other links can be established on the ground. At this time, how can the ground be detected in time? When the transmission link fails, and when the ground transmission link fails, the signal transmission between the base station and the base station controller can be carried out through other transmission links (such as satellite transmission links), so as to achieve the purpose of ensuring that the communication will not be interrupted. The embodiment of the invention provides a signal transmission method, the specific processing flow is as follows figure 1 shown, including:

[0028] Step 101, detecting whether the ground transmission link connecting the base station and the base station controller is interrupted;

[0029] Step 102, when the detection resul...

Abstract

The invention discloses a signal transmission method. The method comprises the following steps of: detecting whether a ground transmission link connecting a base station and a base station controller is interrupted or not; if not, carrying out signal transmission between the base station and the base station controller through the ground transmission link; and if so, carrying out signal transmission between the base station and the base station controller through a satellite transmission link. The invention also discloses the base station, the base station controller and two communication systems. By adopting the invention, the normal running of a communication network can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a signal transmission method between a base station and a base station controller, a corresponding base station, a base station controller and a communication system. Background technique [0002] At present, the base station (Base Transceiver Station, BTS) is set up in the computer room, and the base station is connected with the tower antenna through the antenna feeder system to realize the transmission of the base station wireless signal. The ABIS (interface between BTS and BSC) link between the base station and the Base Station Controller (BSC) realizes the transmission of signaling, voice or data services through cable transmission, satellite transmission or microwave. [0003] A failure of the transmission channel will result in the failure of signal transmission between the base station and the base station controller, for example, the interruption o...
