Method and system for monitoring network quality

Abstract

The invention discloses a method and a system for monitoring network quality. The method comprises the following steps that: a radio remote unit receives a wireless monitoring point command transmitted by a baseband pool unit, sets an antenna receiving and transmitting switch to receive a TD-SCDMAC system signal within a receiving range of the radio remote unit, performs frequency conversion processing on the TD-SCDMAC system signal to acquire a first signal and transmits the first signal to the baseband pool unit; and the baseband pool unit receives the first signal, demodulates the first signal to acquire a second signal and monitors radio signal quality of the radio remote unit according to the second signal. Through the processing, the monitoring strength on an entire network can be enhanced and effective monitoring is provided for the quality management of the radio signal under distributed networking.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a network quality monitoring method and system. Background technique [0002] At present, in the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, the signal coding processing method adopted requires that the sending and receiving signals must strictly implement time synchronization. The frequency domain, time domain, and code domain all have strict requirements, because the TD-SCDM system has higher requirements on signal quality in actual network applications. Therefore, if it is necessary to provide different voice and data services for users in different scenarios, it is necessary to strictly control the signal quality in the system. [0003] At present, the method for monitoring the quality of network operation is relatively complicated and has a single function. In related technologies, the methods for monitoring the quality of networ...

Problems solved by technology

For example, using different methods such as vehicle-mounted and airborne to conduct mobile monitoring within the coverage of the network, this method can better monitor the quality of network operation, but the above-mentioned method cannot be used for testing services with large capacity and high speed. Therefore, It is difficult to guarantee the universality and macroscopicity of monitoring results

[0006] The third method is to monitor the business from the network control layer. This method can monitor the network capacity and business correctness. However, if a fault occurs, it is difficult to directly locate the root cause of the problem.

Among them, the multi-antenna array and the plate antenna set have added the function of analyzing the air signal, but the distributed antenna uses an omni-directional antenna, which cannot directly analyze the quality of the air signal. The problem of poor signal quality offline

[0008] From the above description, it can be seen that in the application scenario of distributed networking of TD-SCDMA system, wireless signal quality monitoring has problems such as lack of monitoring methods, insufficient monitoring efforts, poor reusability of monitoring equipment, and high monitoring costs.
