Embodiment 1

[0041] In this embodiment, the connection relationship between the near-end maintenance station of the base station and the RRU is as follows figure 2 shown. based on figure 2 As shown in the connection, the maintenance method of the base station near-end maintenance station at the RRU near-end is as follows: image 3 As shown, it specifically includes the following steps:

[0042] Step 301, the near-end maintenance station of the base station is physically connected to the RRU main control module of the radio remote unit through the debugging serial port / network port, and establishes a socket (Socket) connection with the RRU main control module.

[0043] The Socket connection refers to using Socket to establish a communication connection between the near-end maintenance station of the base station and the RRU main control module, so as to send data between the two.

[0044] Step 302 , the near-end maintenance station of the base station logs in to the baseband main contr...

Embodiment 2

[0058] In this embodiment, maintenance personnel use the RRU near-end maintenance station to log in to the RRU directly at the near end, and the RRU near-end maintenance station simulates the baseband main control module to issue a commissioning command to the RRU and analyze the maintenance results returned by the RRU, so as to realize all RRU commissioning function.

[0059] The connection relationship of this method is as follows Figure 5 As shown, the RRU main control module includes a commissioning module (D_Stub) and an RRU link layer module. The commissioning module is used to establish / disconnect the Socket connection with the RRU near-end maintenance station, verify the identity of the RRU near-end maintenance station logged in to the RRU, and send the commissioning command issued by the RRU near-end maintenance station to the RRU link layer module; the RRU link layer module connects the RRU sub-module and the interface module of the baseband unit, sends commissioni...

Abstract

The invention discloses a method for maintaining a radio frequency remote module from a proximal end. The process of the method comprises the following steps: a proximal end maintenance station sets up connection with a radio frequency remote unit through a debugging serial port / a net interface and then sends a maintenance command to the radio frequency remote unit; the radio frequency remote unit generates a maintenance result after carrying out maintenance operation according to the maintenance command and then sends the maintenance result to the proximal end maintenance station. The methodof the invention directly sends the maintenance command to the RRU by utilizing the proximal end maintenance station to be connected with the debugging serial port / the net interface of the RRU and obtains the maintenance result from the RRU, thus effectively solving the maintenance problem of the proximal end of the RRU. The method is easy to be used on the current base station system and is easyto be realized.

Description

technical field [0001] The invention relates to base station management and maintenance technology, in particular to a method for near-end maintenance of remote radio frequency modules. Background technique [0002] In a base station system of a wireless network, a single base station is generally divided into a baseband unit and a Radio Remote Unit (RRU, Radio Remote Unit). The baseband unit mainly includes a baseband main control module (NMPT) and an interface module, etc., which are used to complete the interface transmission and control between the base station controller and the base station, clock synchronization, modulation, demodulation, encoding and translation of uplink / downlink signals Code and other operations. The remote radio unit can be designed as an integrated or modularized unit, which is used to complete the processing of intermediate frequency and radio frequency signals, and is also responsible for realizing functions such as duplexer and power amplifie...
