Wireless relay apparatus and wireless communication system

Abstract

The invention provides the wireless relay apparatus and the wireless communicating system. The said wireless relay apparatus includes the wireless transferring dealing cell and the changing cell, the said wireless transferring dealing cell are used to receive the wireless signal send by the original base station and hand it to the changing cell; the said changing cell are used to choose the target base station for the wireless signal send by the said original base station, and the said wireless signal can be send to the target base station. The said wireless communicating system include the wireless relay and the base station, the said wireless signal can connect and communicate through the wireless relay apparatus. The invention makes the new build base station to support the wireless connection, so even the wire connection between the newly build base station and the other base station has the failure, it can be assured to join the community, it can avoid the disturbing to the other base station or the user in the cover adding area. At the same time, the problem of the complicated wire connection between the base stations can be solved.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a wireless relay device and a wireless communication system. Background technique [0002] In order to support the unlicensed frequency band or the shared frequency band, and the system coexist in the same channel or adjacent channel, the IEEE 802.16h standard defines such figure 1 Network architecture. Including: base station (BS) with shared database (Shared DB), authentication server (such as RADIUS server) and shared server (such as CIS). IEEE 802.16h defines a group of BSs networked in Ad-hoc mode as a base station "Community". The base stations in the "community" must be interconnected, such as figure 1 BS1, BS2, and BS3 in BS1, BS2, and BS3 are used to access mutual shared databases and deliver messages related to coexistence. BSs in the "community" must be interconnected with authentication servers and shared servers, and authentication servers and sh...

AI Technical Summary

Problems solved by technology

When the number of base stations in the "community" is large, the wired connection between base stations will be quite complicated

[0005] In addition, assuming that a newly established base station cannot support wired connections, or its wired connection with other base stations fails, when the newly established base station must use license-free frequency bands or shareable frequency bands to coexist with other base stations under co-channel interference or adjacent-channel interference , because it cannot communicate with other base stations, authentication servers and shared servers in the "community", it cannot join the "community", which will cause interference to other base stations or user stations in the coverage area, such as figure 1 Middle Zones A and B

[0006] Moreover, if it is at the scene of a popular international sports event, the number of wireless users will increase sharply, exceeding the capacity of the original base station. At this time, the operator may Emergency transfer of mobile base stations, drive to the game site in the form of a vehicle-mounted station, and move with the transfer of the game field. Since the base station is mobile and temporarily installed, it is not suitable to lay cables for wired connection
