Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0024] The first embodiment of the present invention relates to a network access method of a wireless relay station. In this embodiment, the network accessed by the wireless relay station is a WiMAX network. The specific process is as follows: figure 1 shown.

[0025] In step 101, the wireless relay station performs cell search and selection, and selects a cell (that is, an access point) to initiate a network access process.

[0026] In step 102, the wireless relay station sends an access request message RNG-REQ to the base station to which the cell belongs. The access request message carries an identifier indicating that it is a wireless relay station, and reports cell search and radio environment measurement results.

[0027] In step ...

Abstract

The invention relates to the wireless communication field, and discloses a method, a device and a system for network access of a wireless relay station, which ensure that the network access efficiency of the wireless relay station is improved. In the invention, before the registration process of the wireless relay station is completed, the wireless relay station sends uplink information to a control station of a wireless access network; the uplink information carries identification which shows as an identification number of wireless relay station; and the control stations carry out the access control and make the route choice, and accesses the wireless relay station to a network according to the result of the access control and route choice. After the registering is completed, the configuration of relay parameters in the wireless relay station is carried out, and the routing is established and updated.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the network access technology of a wireless relay station. Background technique [0002] In the wireless communication system, due to the attenuation of the path of electromagnetic waves, especially the electromagnetic waves using high-frequency carriers, and the occlusion of buildings, etc., the coverage of the base station (Base Station, referred to as "BS") is limited, making wireless in some areas The communication signal strength is low, and the communication quality of a mobile station (Mobile Station, "MS" for short) (also called a terminal) located in these areas becomes very poor. In order to solve the problem of small base station coverage caused by electromagnetic wave attenuation, a common solution is to use a relay station (Relay Station, referred to as "RS") to relay the wireless communication signal between the base station and the mobile station, and compensa...
