Embodiment Construction

[0050] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] The embodiments of the present invention are implemented based on a spectrum sharing system. For description, a system regulated by the IEEE802.22 standard is taken as an example, but the present invention is not limited thereto. Those skilled in the art should understand that there are many spectrum sharing systems, and all of them can be applied to the present invention. The above settings are only illustrative.

[0052] According to the IEEE802.22 standard specification, the WRAN system needs to coexist with the TV system. The WRAN system is a secondary system and needs to avoid harmful interference to the main TV system. When the primary system is detected on the working channel of the WRAN system, the CPE will inform its serving BS and wait for instructions from the BS. Once receiving the spectrum management instruction sent by the BS, t...

Abstract

The embodiment of the invention provides a method, a device and equipment for managing communication channels of a frequency spectrum sharing system. In the slave system of the frequency spectrum sharing system, a back-up communication channel comprises complete back-up communication channels and partial back-up communication channels; if a main system is detected, the slave system inquires whether an available complete back-up communication channel exists; if the complete back-up communication channel does not exist, the slave system inquires whether the partial back-up communication channels are available; if the partial back-up communication channels are available, the slave system starts a communication channel competition program to carry out communication channel competition with a neighbor BS thereof; and if the partial back-up communication channels win in the communication channel competition, the slave system switches into the victorious communication channel and rebuilds connection. In this way, the connection-dropping rate of the slave system is lowered, and the QoS of the slave system is also improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a channel management method, device and equipment of a frequency spectrum sharing system. Background technique [0002] In the spectrum sharing system under the licensed spectrum, the master system and the slave system share a certain spectrum resource. When the master system does not occupy this spectrum resource, the slave system can use this idle resource opportunistically. The main system has privileged use of the spectrum and can access it at any time. The slave system uses the spectrum opportunistically. When the master system uses the spectrum, the slave system needs to avoid it. In order to avoid harmful interference to the master system, the slave system must periodically detect the presence of the master system. When detecting the existence of the master system, the slave system must give up the current channel immediately. In order to guarantee the quality of serv...
