Transmission channel allocation method and device

Abstract

The invention provides a transmission channel allocation method and device. The transmission channel allocation method comprises: detecting whether a first-type wireless signal and a second-type wireless signal occupy completely a preset frequency band in a preset space range, wherein the first-type wireless signal and the second-type wireless signal share the preset frequency band; if the first-type wireless signal and the second-type wireless signal do not occupy completely the preset frequency band, allocating a channel, in which the currently transmitted first-type wireless signal and second-type wireless signal are not overlapped, as a transmission channel to a to-be-transmitted second-type wireless signal; if the first-type wireless signal and the second-type wireless signal occupy completely the preset frequency band, allocating a transmission channel to the to-be-transmitted second-type wireless signal according to the occupancy situation of the frequency band by the currently transmitted first-type wireless signal and second-type wireless signal. According to the transmission channel allocation method and device, which are provided by the invention, a technical problem that signal interference is severe when wireless signals of different types occupy the same frequency band in the prior art is solved, and technical effects of reducing interference among signals and ensuring reliability of data transmission are achieved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a transmission channel allocation method and device. Background technique [0002] With the continuous development of smart home, WIFI technology and Zigbee technology have also been widely used. In the same environment, there will not only be a large number of WIFI signals, but also a large number of Zigbee signals, because the IEEE 802.11b / g standard followed by WIFI and the IEEE 802.15.4 standard followed by Zigbee belong to 2.4G frequency band, therefore, there will inevitably be mutual interference between the two, especially the interference of WIFI signal to Zigbee signal, if it is not processed, it is bound to seriously affect the transmission quality of Zigbee signal. [0003] For how to reduce the interference between the WIFI signal and the Zigbee signal, no effective solution has been proposed yet. Contents of the invention [0004] An embo...
