Embodiment Construction

[0149] The present invention will be described in detail below in conjunction with specific embodiments.

[0150]A channel switching method of the present invention such as Figure 6 shown, including the following steps:

[0151] In step s601, the client device detects whether there is interference in the frequency band used, and if there is interference, it sends a baseband link management measurement report message to the base station, and the message includes interference indication information.

[0152] In step s602, the base station performs data analysis according to the interference indication information, and judges whether the interference comes from a licensed system, and if so, proceeds to step s603.

[0153] In step s603, the base station sends a channel switch request message CHS-REQ to the client device, and the message includes channel switch cause information CAUSE.

[0154] In step s604, the client device switches from the currently used channel to an idle c...

Abstract

This invention discloses a channel switching method: the client device detects whether the used band has interference, if has, it sends base band link management measurement report news to the base station, which includes interference instruction news. According to it, the base station conducts data analysis to judge whether the interference comes from licensing system, and if so, the base station sends CHS-REQ to the client equipment, which includes channel switching reasons information CAUSE. The client equipment switches from the current used channel to the idle one. The invention also provides an adaptive method of interference detection threshold.

Description

technical field [0001] The invention relates to communication network technology, in particular to a channel switching method and an adaptive method of an interference detection threshold. Background technique [0002] In the existing communication network, there is a license-free system whose operating frequency band does not require authorization, such as wireless regional network (WRAN, Wireless Regional Area Network), wireless local area network (WLAN, Wireless Local Area Network), etc. system. The license-free system coexists with the licensed system in the working frequency band. For example, the WRAN system needs to coexist with the wireless digital TV (DTV, Data TV) system, but the license-free system cannot interfere with the licensed system. When it is found that the licensed system is applicable to a certain frequency band , the license-free system must unconditionally withdraw from this frequency band and jump to other frequency bands to continue working. The a...
