Embodiment Construction

[0047] figure 1 It is a schematic flowchart of a wireless network access method in the prior art. First, in step 101, the mobile station synchronizes with the downlink channel of the base station, and sends a ranging request message to the base station using dedicated resources. Next, in step 102, the base station sends a ranging response message to the mobile station. Then, if figure 1 As shown, the access process ends. Although figure 1 Exemplary only, but it can be easily seen that figure 1 The wireless network access method shown does not involve relay stations. In some application situations, a small number of shadowing holes exist in cells such as base stations, or base stations are deployed in low-density areas, and at this time mobile stations cannot communicate normally. In addition, when the mobile station is located at the edge of the cell or in a deep fading area, the mobile station should adjust the transmit power to the maximum value, at this time, the batt...

Abstract

The invention provides a network accessing method of relay accessing network, said relay accessing network includes: base station, relay station and movable platform, said network accessing method includes following steps: the registering step of relay station; the synchronization and initialization step of movable platform; detecting step, said relay station detects the signal quality parametersof movable platform; filtering step, when said movable platform works as the movable platform of relay station, the distance measuring messages and signal quality parameters of movable platform is transmitted to the base station; gathering step, said base station gathers the signal quality parameters of movable platform and signal quality parameters of relay station; and combining the detecting steps, said base station combines the signal quality parameters to decide to return the movable platform to the base station or the relay station. The invention also provides relay station, base station and wireless communication system which use said method.

Description

technical field [0001] The present invention generally relates to a broadband wireless access network, and more particularly relates to a wireless multi-hop (multi-hop) relay access network access method, and a relay station, a base station and a wireless communication system using the access method. Background technique [0002] Mobile multi-hop relay is a very new concept in IEEE 802.16 standardization. In July 2005, the IEEE 802.16 group established the "Mobile Multi-Hop Relay" research group to study WiMAX relay technology and define its concept and application. WiMAX (World Interoperability for Microwave Access), which means global interoperability for microwave access, is a wireless metropolitan area network technology based on the IEEE802.16 standard. WiMAX can be better understood compared to known Wi-Fi. Wi-Fi is a wireless local area network access technology, and its signal transmission radius is only a few hundred meters. WiMAX is a wireless metropolitan area ...
