Channel detecting and switching method, base station and system

Abstract

The present invention discloses the detection and switching method of channels. The method includes two steps; firstly, in the silent period of a system, a base station detects a channel waiting for being detected; secondly, when the channel waiting for being detected is determined to be idle, the operation of the base station is switched to the channel waiting for being detected. The present invention also discloses the base station and the detection and switching system of channels, and wherein, the base station of the system includes a channel detection module and a channel switching module; the channel detection module is used to detect the channel waiting for being detected in the silent period of the system, when the channel waiting for being detected is determined to be idle, the channel detection module sends a channel switching instruction carrying the identifier information of the channel waiting for being detected to the channel switching module; after the channel switching module receives the channel switching instruction, according to the channel identifier information carried by the instruction, the base station is switched to the idle channel waiting for being detected. By utilizing the detection and switching method of channels, the base station and the system which are provided by the present invention, the base station can be switched to the idle channel in the process of operation after accessing a network, thus increasing the utilization rate of system resources.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a channel detection and switching method, base station and system. Background technique [0002] Broadband wireless access technology is currently developing vigorously, and the technology of using wireless resources to carry out broadband metropolitan access has strong vitality and market space. At the same time, wireless spectrum resources are very precious, especially in unplanned areas or unlicensed frequency bands, there are often multiple base stations (BS, Base station) operating on the same channel, resulting in mutual interference between their systems. [0003] In order to solve this problem, when a new base station initially enters the network, it must first adopt a certain spectrum sensing method to detect whether other users occupy the frequency band. If an idle channel can be detected, it will select the idle channel as its own working channel. If no idle channe...

Problems solved by technology

During the working process of the base station after entering the network, even if there is an available idle channel, the base station cannot know it, and of course it will not perform channel switching, which will inevitably lead to the time-sharing channel between the base station and the neighbor base station.

The resource utilization rate of the time-sharing shared channel is lower than that of the exclusive channel. At the same time, the existence of idle channels that are not used will inevitably cause waste of resources.
