Problems solved by technology

However, full-channel scanning will increase the service delay of the working channel, and the target device selected by the signal strength may not be optimal; the negotiation process is an asynchronous working mode, and there may be packet loss and retransmission, which may lead to switching The process takes a long time; therefore, the performance and effect of roaming switching in the current master-slave hybrid network are not good

Abstract

The embodiment of the invention discloses a communication method, equipment and system for master-slave hybrid networking, relates to the field of communication, and aims to realize simple and rapid roaming switching in the master-slave hybrid networking and improve the performance and effect of roaming switching. The method comprises the following steps that: MD and SD obtain the downlink signalstrength of each UD in a coverage area and the downlink physical layer rate of a link between the MD and each UD in the coverage area; the MD and the SD determine respective expected link bandwidth corresponding relations; the MD and the SD broadcast respective expected link bandwidth corresponding relations; the UD acquires downlink signal intensity from each connectable equipment to the UD; andthe UD selects a target equipment from the one or more connectable equipments to initiate switching according to a preset rule based on the corresponding relationship between the downlink signal strength and the expected link bandwidth.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular to a communication method, device and system for master-slave hybrid networking. Background technique [0002] With the rapid development of wireless broadband technology, the radio frequency coverage of a single device can no longer meet the requirements of large-scale and high-throughput performance. Therefore, a master-slave hybrid network in which multiple wireless devices cooperate has gradually become an industry trend. [0003] figure 1 A network topology architecture of a master-slave hybrid network is illustrated, and the topology includes a master device (master device, MD), a slave device (slave device, SD), and a user device (user device, UD). E.g, figure 2 The schematic wireless local area network (wireless fidelity, Wi-Fi) centralized management network based on an access point controller (access point controller, AC) is a master-slave hybri...
