Embodiment Construction

[0030] The present invention is a method for solving the coverage blind area of ​​a WLAN network by using a terminal relay, and implementing the method can effectively solve the problem of base station signal coverage in a complex environment and expand the scope of the WLAN network.

[0031] The base station and the terminal equipment establish the basic neighbor list through the broadcast message, and at the same time establish the topology relationship with the neighbors according to the hop count and device type identification in the message, and establish a basic tree routing table. When the destination address that the child node needs to send is not in the neighbor list, it will be sent directly to the root node; when the destination address that the root node needs to send is not in the neighbor list, the routing request process will be initiated. The terminal device passes through a series of terminal nodes through multiple hops to provide a long end-to-end communicati...

Abstract

The invention relates to a method for solving a WLAN network coverage blind area by a terminal relay, which comprises the steps of: building a treelike route table according to the quality and the hop count of a signal and the type of equipment; valuing the quality of a node signal; improving the update frequentness of a node to be adapted to switching under the environment with high-speed movement; caching a report in the process of switching; and controlling the power of package level. Compared with the prior art, the method has the following advantages of expanding the network coverage, saving the building cost with the terminal relay, fast building a link based on the treelike route and optimizing data link and improving data transmission speed.

Description

technical field [0001] The present invention relates to a method for solving blind areas covered by a WLAN network, in particular to a method for solving blind areas covered by a WLAN network by using a terminal relay. Background technique [0002] At present, the methods to solve the coverage blind area mainly include adding access point devices (APs), repeaters or switches; improving the signal sensitivity of WLAN devices, increasing signal transmission power, and so on. However, these solutions have the following disadvantages: adding equipment will increase the cost of the enterprise and increase the complexity of operation and maintenance; the installation conditions of access point equipment in some application environments are not easy to meet; high transmission power will cause overloading of receiving equipment; Increase in-band and out-of-band electromagnetic interference, affecting the normal operation of adjacent channel equipment; high transmit power cannot redu...
