Embodiment Construction

[0012] The basic idea of ​​the present invention is: when the data channel changes, for the affected base station, the local device makes other base stations and non-local devices update the routing table by sending the GARP broadcast packet on behalf of the base station; and sends the MAC-IP list through the base station The method prompts non-local devices to send GARP broadcast packets to update the routing tables of local base stations and local devices. The invention provides a reliable whole-network routing table update mechanism for the data path reconstruction in the self-relay system, and provides support for the rapid recovery of the data path.

[0013] The specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] The embodiment of the present invention is based on a wireless self-relay communication system, such as figure 1 As shown, base stations (BTS) are relayed through dedicated wirele...

Abstract

The invention discloses a GARP (Generic Attribute Registration Protocol)-based data channel updating method in a wireless automatic relay communication system. The GARP-based data channel updating method comprises the steps that a base station analyzes an MAC (Media Access Control) address, an IP (Internet Protocol) address and an equipment identity (EID) of each data packet to generate an MAC-IP-EID routing list; when one channel fails and a standby channel is started, the base station of which a channel is changed replaces a local device to send a GARP broadcast packet to other base stations, MAC-IP lists of nonlocal devices form a UDP (User Data Protocol) broadcast packet to be sent to other base stations; after receiving the GARP broadcast packet, the other base stations analyze and update the MAC-IP-EID routing list, and continuously broadcast the GARP broadcast packet to the local device and a downstream base station; and after receiving the UDP broadcast packet, the other base stations search the local device according to the MAC address in the MAC-IP list in the UDP broadcast packet and transmit the GARP broadcast packet and continuously broadcast the UDP broadcast packet to the downstream base station. According to the invention, when the main wireless channel and the standby wireless channel are switched, the routing list can be updated, data services are continuously carried out, and therefore, reliable data services are provided for a user.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication system for self-relaying through a dedicated wireless broadband terminal. Background technique [0002] In the Chinese invention patent application with the application number 201110229412.9 "A Method for Effectively Solving Base Station Wired Transmission", a dedicated wireless broadband terminal is used to connect the IP backbone network and the base station to solve the problem that the base station cannot be connected to the backbone through wired transmission under special circumstances. network problem. The wireless self-relay system constructed by the method described in this patent application is as follows: figure 1 As shown, each base station is relayed by a dedicated wireless broadband terminal to form a backbone network. For a channel that may fail, a backup channel is usually provided to provide redundant protection for the main channel...
