Abstract

The embodiment of the invention provides a channel occupation method, a master device and a slave device. The master device broadcasts a beacon frame carrying a beacon period within a preset range, the beacon period is used for indicating the time the master device occupies the channel, when a message carrying a network allocation vector is received in a waiting time slot of the beacon period, master device broadcasts the beacon frame within the preset range again after waiting for the occupation time of the channel corresponding to the network allocation vector. By sending the low-speed and high-priority beacon frame to participate in the channel contention, when the master device receives the message carrying the network allocation vector in the waiting time slot, the master device broadcasts the beacon frame again after waiting for the occupation time of the channel corresponding to the network allocation vector without randomly evading any time, therefore compared with the method of randomly evading for a period of time in the competition mechanism in the prior art, the method provided by the embodiment of the invention has the advantages of improving the success rate of the master device to occupy the channel, meanwhile reducing the collision probability with the other competing devices and improving the utilization rate of the channel resources.

Description

technical field [0001] The embodiment of the present invention relates to the field of wireless network communication, in particular to a method for occupying a channel, a master device and a slave device. Background technique [0002] Before the invention of Wireless Local Area Networks (WLAN for short), if people wanted to connect and communicate through the network, they had to use physical cables-copper twisted wires to form an electronic running path. Fiber optics were invented. When the network develops to a certain scale, people find that it is very difficult to set up, disassemble, or re-layout and rebuild the wired network on the original basis, and the cost and price are also very high, so the WLAN networking method Came into being. WLAN based on the IEEE802.11 standard wireless local area network allows wireless connection in the local area network environment using the 2.4GHz or 5GHz radio frequency band in the ISM frequency band that does not need to be author...
