Embodiment 1

[0048] 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 method for the base station near-end maintenance station to achieve maintenance at the near-end of the RRU is as follows: image 3 As shown, it specifically includes the following steps:

[0049] Step 301: The near-end maintenance station of the base station is physically connected to the RRU main control module of the remote radio unit through the debugging serial port / network port, and establishes a socket connection with the RRU main control module.

[0050] 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.

[0051] Step 302: The near-end maintenance station of the base station logs in to the baseband main co...

Embodiment 2

[0065] In this embodiment, the maintenance personnel use the RRU near-end maintenance station to directly log in to the RRU at the near end. The RRU near-end maintenance station simulates the baseband main control module to issue a commissioning command to the RRU, and analyzes the maintenance results returned by the RRU to achieve all RRU commissioning function.

[0066] 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 that logs in to the RRU, and send the commissioning commands issued by the RRU near-end maintenance station to the RRU link Layer module: The RRU link layer module connects the RRU submodule and the interface module of the baseband unit, sends commissioning comm...

Abstract

A near-end maintaining method of radio remote module includes setting up connection with radio remote module by near-end maintenance desk through debugging serial interface / network interface and sending maintenance command to radio remote module, generating maintenance result after maintenance operation is executed by radio remote module according to maintenance command then sending said result to near-end maintenance desk.

Description

Technical field [0001] The invention relates to base station management and maintenance technology, in particular to a method for near-end maintenance of a radio remote unit. Background technique [0002] In the base station system of the 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 master control module (NMPT) and an interface module, etc., which are used to complete the interface transmission, control, clock synchronization between the base station controller and the base station, and the modulation, demodulation, encoding and translation of the uplink / downlink signal. Code and other operations. The remote radio unit can be designed to be integrated or modular to complete the processing of intermediate frequency and radio frequency signals. It is also responsible for realizing functions such as duplexers and power amplifiers. The logic function com...
