Wireless relay networking system and method

Abstract

The invention provides a wireless relay networking system and method. The wireless relay networking system comprises relay devices arranged in different communication stations. Each relay device comprises at least one of a wireless relay terminal and a wireless relay base station. The wireless relay terminals and the wireless relay base stations build routing forwarding relations with local core networks in a wired mode, the wireless relay terminals are connected into peripheral relay base stations in a wireless mode, the wireless relay base stations are connected with peripheral wireless relay terminals in a wireless mode to build communication links with peripheral core networks, the wireless relay terminals forward messages transmitted through the local core networks to the peripheral relay base stations and forward messages received from the peripheral relay base stations to the local core networks, the wireless relay base stations forward messages transmitted by the local core networks to the peripheral wireless relay terminals and forward messages received from the peripheral wireless relay terminals to the local core networks, wireless relay relations are allocated between the wireless relay terminals and the peripheral relay base stations, and wireless relay relations are allocated between the wireless relay base stations and the peripheral wireless relay terminals.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless relay networking system and method for interconnecting and intercommunicating a plurality of communication sites to form a unified communication network to realize communication coverage in a relatively large range by means of wireless relay. Background technique [0002] With the development of mobile communication and relay technology, in areas where the coverage of the base station is limited, the function of extending the coverage can be completed through the relay node. For example, Chinese patent 200610144164.7 discloses a new untrusted communication networking method based on relay technology. By flexibly setting relay stations to reduce the requirements for base station capabilities, expand its coverage, reduce interference from neighboring base stations, and provide diversity gain. Improve system spectrum efficiency. [0003] However, w...

Problems solved by technology

[0003] However, when establishing a communication network in the wild, in emergency places, or in mobile places, a single communication station often cannot meet the requirements of communication coverage, and multiple communication stations need to be interconnected to form a larger-scale communication network.

Due to the problem of lack of transmission lines, difficult engineering construction, and high cost in realizing relay networking through wired methods, and in the above-mentioned scenarios, sometimes it is impossible to interconnect multiple communication sites through wired methods
