Self-cure monitoring method and device of digital remote radio system

Abstract

The invention discloses a self-repair monitoring method of digital radio frequency remote system, therefore each functional module in baseband unit and radio frequency unit of digital radio frequency remote system is monitored and the functional modules at the abnormal state are reset, and the monitoring main machines of baseband unit and radio frequency remote unit have the following functions: monitoring the run state of functional modules by at least one monitoring accessory machine in monitoring main machine schedule uplink and / or downlink which is connected with the functional modules; the monitoring accessory machine sending at least one reset signal to the functional modules when the run state is abnormal and then the functional modules reset according to the reset signal. In addition, the invention also discloses a corresponding self-repair monitoring method. Firstly, the operation normalization of digital radio frequency remote system is ensured, thereby realizing intellectualized self-repair process; secondly the material cost and production cost is reduced.

Description

【Technical field】 [0001] The invention relates to mobile communication repeater technology, in particular to a self-healing monitoring method and device for a digital radio remote system. 【technical background】 [0002] In the coverage of the mobile communication network, the digital remote radio system, as the remote equipment for mobile communication signal coverage, has higher requirements on the reliability and availability of the system, especially stricter requirements on the realization of system monitoring; but Due to the different coverage conditions and environments, plus the problems of the system itself, such as the deviation of the operation of the hardware subsystem and the more or less defects in the design of the software subsystem, the software or communication links are abnormal, resulting in In the system, the baseband unit and the remote unit monitor the host module and the uplink and downlink functional modules cannot exchange data, the baseband unit and...

[0002] In the coverage of the mobile communication network, the digital remote radio system, as the remote equipment for mobile communication signal coverage, has higher requirements on the reliability and availability of the system, especially stricter requirements on the realization of system monitoring; but Due to the different coverage conditions and environments, plus the problems of the system itself, such as the deviation of the operation of the hardware subsystem and the more or less defects in the design of the software subsystem, the software or communication links are abnormal, resulting in In the system, the baseband unit and the remote unit monitor the host module and the uplink and downlink functional modules cannot exchange data, the baseband unit and the remote unit cannot communicate and transmit data, and the digital radio remote system reports the misoperation alarm information to the mobile Communication Network Monitoring Center

If it cannot be solved in time, on the one hand, the system will not work normally or even be paralyzed due to some minor problems, which will affect the coverage of the mobile communication network;
