Switching method and system for ring network wireless equipment

Abstract

The invention discloses a switching method and system for ring network wireless equipment. The wireless equipment includes core wireless equipment and remote wireless equipment. The core wireless equipment forms a ring network with two or more remote wireless equipment through its own two ports; The method includes: when the core wireless device detects that the bit error rate of its own two-port line is within the set threshold range, it sends a valid control character, and when it is not within the set threshold range, it sends an invalid control character; wherein, the valid control character sent by the two ports of the core wireless device The control characters are different; when the remote wireless device detects that the line bit error rate of the receiving side of its main port is within the set threshold range, it forwards the valid characters received from the slave port to the main port; when it is not within the set threshold range, the main port Invalid characters sent; the remote wireless device continues to send invalid control characters to the slave port. The invention improves the stability of the RRU networking mode.

Description

technical field [0001] The invention relates to a switching technology of ring network wireless equipment, in particular to a switching method and system in a ring network structure composed of BBU and RRU in a wireless communication network. Background technique [0002] In order to achieve better network coverage, a distributed base station architecture is installed in some network coverage blind areas such as office buildings and elevators. The distributed base station architecture mainly includes a remote radio unit (RRU, Remote Radio Unit) and an indoor baseband processing unit (BBU, Building Baseband Unit). The RRU and the BBU are connected by optical fiber, and the RRU is connected through a coaxial cable and a power splitter ( coupler) etc. to the antenna. One BBU can support multiple RRUs. The BBU is centrally placed in the machine room, and the RRU can be installed in corresponding places such as each floor, inside the elevator, etc. according to the signal cover...

AI Technical Summary

Problems solved by technology

Once a certain RRU on the link connected to the BBU fails, the link between the RRUs fails, or the link between the RRU and the BBU fails, the failed RRU or the RRU behind the failed link will be in a disconnected state, causing this part of the RRU fail

Therefore, although the current RRU networking method is simple, its network structure is relatively fragile. Once a network failure occurs on a certain link, some RRUs may fail.
