Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the channel switching initiator needs to send WiFi frames multiple times in order to ensure that the receiving end actually receives the WiFi channel change information, which leads to a long time-consuming channel switching. A kind of communication equipment, system and channel switching method

Embodiment 1

[0038] figure 2 A communication system is shown, which includes two kinds of interactive communication devices. For the convenience of distinction, in this embodiment, the communication device on the left side of the figure is called the initiator communication device C, and the communication device on the right side of the figure is called the receiver Communication device D, the initiator communication device C can manage and monitor channels, and notify the receiver communication device D to switch WiFi channels, and the receiver communication device D can switch WiFi channels according to the requirements of the initiator communication device C . In the BSS formed by the initiator communication device C and the receiver communication device D, the initiator communication device C can be used as a WiFi access point (AP), and the receiver communication device D can be used as a WiFi Workstation (STA).

[0039] Wherein, the initiator communication device C includes a first...

Abstract

The invention discloses communication equipment, a communication system and a channel switching method. The communication equipment comprises a first WiFi module, a first Bluetooth module, and a second Bluetooth module which is used for sending WiFi channel replacement information to receiving end communication equipment through a Bluetooth link. The receiving end communication equipment further comprises a second WiFi module located in the same wireless local area network as the first WiFi module, and the information is used for notifying the second WiFi module to switch a WiFi channel. According to the invention, a BT link is used for transmitting the WiFi channel replacement information; the purpose of quickly switching the WiFi channel is achieved; particularly, when the WiFi module ofthe communication equipment for receiving channel switching is in a dormant state, the communication equipment for initiating channel switching only needs to send WiFi channel replacement informationonce to ensure that the communication equipment for receiving channel switching receives the information in time; WiFi channel replacement is started quickly; and the switching time consumption is reduced.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a communication device, a system and a channel switching method. Background technique [0002] WiFi (a wireless network technology) and Bluetooth (Bluetooth) technology are currently the most widely used wireless connection technologies, and WiFi has the characteristics of high speed, high delay, and high power consumption. BT is suitable for low-speed, low-latency, and low-power consumption scenarios. Although these two technologies can already be integrated in the same wireless communication chip, the WiFi and BT connections still exist independently between two devices that have established a WiFi and BT dual connection. [0003] Most scenarios of WiFi connection run in infrastructure mode (interconnected working mode through AP), that is, one AP (access point), and another or more clients as STA (workstation or station), together form a BSS (basic service s...
