Wireless mesh network efficiently handles terminal mobile method

Abstract

The invention discloses a method for efficiently processing terminal mobility in a wireless Mesh network, and mainly solves the problem of high data loss rate when a terminal switches an access point in prior art. The method comprises the following steps: 1, a received signal strength threshold is set for the access point; 2, after the terminal and the access point are connected, the access point disconnects the connection with the terminal according to the received signal strength threshold; 3, the access point distributes a buffer memory space in a memory to temporarily store data sent to the terminal, and forwards the data in the buffer memory space to a new access point after receiving terminal position information; 4, the access point, after receiving terminal table item deletion information, deletes terminal table items and releases the buffer memory space; 5, the new access point, after being connected with the terminal, sends the terminal position information to the original access point and a gateway node; and 6, the gateway node sends the terminal table item deletion information to the original access point. According to the method for efficiently processing the terminal mobility in the wireless Mesh network disclosed by the invention, the data loss rate when the terminal switches the access point is reduced; and the method can be used in the wireless Mesh network in need of efficiently processing the terminal mobility.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a terminal mobility management method. The invention can be used in the scenario of processing terminal movement in the wireless Mesh network, and improves the problem of data loss caused in the process of terminal movement. Background technique [0002] Wireless Mesh network is a wireless multi-hop communication network developed based on wireless self-organizing network. When mobile terminals in this network gradually move away from the current Mesh network access point MAP, they need to disconnect from the current MAP and connect to the network. When entering a new MAP, there will be a high packet loss rate during the process of switching MAPs. However, the routing protocol of the wireless mesh network ignores the mobile problem of the terminal, and leaves this problem to the specific network equipment manufacturer. Therefore, it is necessary to propose a mobile p...
