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
The present invention relates to wireless communication field, relate in particular to and a kind ofly carry out wireless communication system from relaying by the private radio wide-band terminal.
Background technology
In application number is 201110229412.9 Chinese invention patent application " a kind of method of effective solution base station wire transmission ", connect IP backbone and base station by a private radio wide-band terminal, can't be linked into by wire transmission the problem of backbone network with base station under the solution particular surroundings.Adopt that the described method of this patent application makes up wireless from relay system as shown in Figure 1; form backbone network through private radio wide-band terminal relaying between each base station; for the passage that may break down, be typically provided with an alternate channel, for the main channel provides redundancy protecting.When above-mentioned wireless primary channel in relay communications system is switched, thereby the former channel information that records in the base station data business will lose efficacy and caused the data service fault.Based on this background, the present invention proposes a kind of effective mechanism and come the data reconstruction channel information.
Summary of the invention
The method that the present invention proposes is applicable to wireless from relay communications system, forms backbone network by private radio wide-band terminal relaying between each base station in this communication system, and described method comprises:
MAC Address, IP address and the device number EID of each packet resolved in the base station, generates the MAC-IP-EID routing table;
When a certain passage broke down and enables alternate channel, the base station that passage changes replaced its local device to send the GARP broadcast packet to other base station, and the udp broadcast bag of MAC-IP tabulation composition with non-local equipment sends to other base station simultaneously;
After other base station receives the GARP broadcast packet, resolve and upgrade its MAC-IP-EID routing table, simultaneously the GARP broadcast packet is continued to be broadcast to its local device and base station, downstream;
After other base station received the udp broadcast bag, the MAC Address of tabulating according to MAC-IP in the udp broadcast bag retrieved its local device and for sending out a GARP broadcast packet, simultaneously the udp broadcast bag is continued to be broadcast to the base station, downstream.
Undertaken in the wireless communication system of relaying, adopting method provided by the invention by the private radio wide-band terminal, can be so that radio channel routing table after masterslave switchover occurs obtains upgrading, data service is proceeded, thereby provides reliable data, services for the user.
Description of drawings
Fig. 1 is the backbone network topology schematic diagram of the embodiment of the invention;
Fig. 2 is the process chart after the line switching instruction is received in the base station of the embodiment of the invention;
Fig. 3 is the process chart that the udp broadcast bag is received in other base station of the embodiment of the invention.
Embodiment
Basic thought of the present invention is: when data channel changed, for affected base station, local device was sent out the mode of GARP broadcast packet so that other base station and non-local renewal of the equipment routing table by base station generation; And impel non-local equipment to send the routing table that the GARP broadcast packet upgrades home base stations and local device by the mode of base station transmission MAC-IP tabulation.The present invention rebuilds the reliable the whole network routing table update mechanism that provides for the data path in relay system, for the rapid recovery of data path provides support.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
The embodiment of the invention is wireless from relay communications system based on one, as shown in Figure 1, forms backbone network by private radio wide-band terminal (SUT) relaying between base station (BTS).Wherein, for the BTS2-BTS4-BTS5 passage, use SUT3 to set up an alternate channel, this passage just keeps operating state, does not process any data service.
For each base station, the terminal equipment that three types is arranged: wireless terminal, the network port device that links to each other with the base station through switch and the terminal equipment that links to each other through SUT, the above two are local device, be non-local equipment through what SUT linked to each other, for these three kinds of equipment, MAC Address, IP address and the device id (EID) of each packet resolved in the base station, generates the MAC-IP-EID routing table.When SUT5 broke down, the BTS2-BTS4-BTS5 passage disconnected, and becomes BTS5-BTS2-BTS4 after alternate channel is enabled, and it is chaotic that the routing table of preserving in this three stylobates station can cause data channel to occur, and must upgrade.Take BTS5 as example, the concrete processing procedure of present embodiment is:
A, webmaster are switched instruction to base station (BTS5, BTS2, the BTS4) transmitting line that exists path to change, and informing base station carries out the line switching operation;
B, as shown in Figure 2, BTS5 receives the line switching instruction, traversal local mac-IP-EID routing table sends ARP request bag to confirm whether the user exists for local device, responds according to the follow-up ARP that receives to replace this equipment to send the GARP broadcast packet.Then its MAC-IP is put into tabulation for non-local equipment, wait for UDP packet broadcast of composition other base stations to the backbone network of to tabulate after traversal is finished.
After other base stations in C, the network receive the udp broadcast bag of BTS5 transmission, as shown in Figure 3, retrieve local device according to the MAC Address in the udp broadcast bag, after ARP confirms, replace this equipment to send the GARP broadcast packet, simultaneously the udp broadcast bag is continued to be broadcast to the base station, downstream;
After other base stations in the network receive the GARP broadcast packet that BTS5 generation sends out, resolve and upgrade its former MAC-IP-EID record, it is continued to be broadcast to simultaneously the base station, downstream on local device and the network.
By above-mentioned steps, the routing table in the network on the routing table of all terminal equipments and all base stations has all obtained renewal.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
