Method, device and system for remotely maintaining remote radio unit (RRU)

Abstract

The invention discloses a method, device and system for remotely maintaining a remote radio unit (RRU), which are used for realizing the all-around remote management of the remote radio unit and reducing later maintenance cost. The method comprises the following steps that: base station main equipment receives an RRU management command sent by an operating maintenance terminal, and on the basis of an Ir interface standard, re-encapsulates the received RRU management command into a transparent channel message according to a message format for transparent transmission, and sends the transparent channel message to a corresponding RRU to indicate the corresponding RRU to execute relevant operations. Therefore, the all-around remote operating maintenance function of the RRU can be realized; furthermore, when the management content of the RRU is changed, the processing software of the RRU and the relevant parameters of the operating maintenance terminal are required to be modified only; and the method, the device and the system have the advantages of low later maintenance cost and strong feasibility. The invention also discloses the base station main equipment for remotely maintaining the RRU, the RRU and the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for remotely maintaining remote radio equipment. Background technique [0002] With the development of communication technology, in order to solve the problem of signal coverage in large buildings, basements, subways and other places where traditional wireless signals cannot reach, at present, indoor distribution systems are used to achieve wireless signal coverage in these places. [0003] In the existing indoor distribution system, distributed base stations are generally used to achieve signal coverage. refer to figure 1 As shown, the distributed base station mainly includes base station main equipment and remote radio equipment (RRU). The base station main equipment is usually located in the operation room, while the RRU is distributed in difficult-to-reach locations where the base station main equipment cannot be placed, such as the top of the an...

[0008] 2. The management content exceeds the definition scope of the Ir standard

Although the initial development cost and subsequent maintenance cost of this solution are relatively low, however, since the RRU and the base station main equipment are usually set up in two places, multiple RRUs managed by the same base station main equipment may be scattered in multiple locations that are not easy to reach Therefore, the operation and maintenance terminal is directly connected to the RRU for operation and maintenance. The operation and maintenance terminal can only establish a connection with the RRU's local network port, requiring the operator to go to the location of the RRU to operate, and the location of the RRU is usually It is difficult to reach, and it is basically impossible to manage multiple RRUs at the same time

Therefore, for operators, in order to manage and maintain each RRU of the main equipment of the base station one by one, they need to go to the location where each RRU is located for operation. The operation cost is extremely high, the execution efficiency is low, and the feasibility is also very low.
