Signal monitoring device and method for mobile communication system

Abstract

The invention relates to a signal monitoring device and method for a mobile communication system. The signal monitoring device comprises two detection channels, namely, an input signal detection channel and a reflection signal detection channel; for improving the detection precision of the two channels, the frequency conversion is respectively carried out on the two channels, so that signals under each mobile communication system are subjected to down conversion into a fixed intermediate frequency, and then the demodulation is carried out. A synchronous signal extraction unit is further arranged inside the signal monitoring device, and is used for extracting synchronous signals in a time division duplex communication system and controlling a radio frequency switch, so that the condition that only a downlink of the time division duplex communication system can be detected is ensured. The signal monitoring device has good adaptability, and can be used for detecting mobile signals (which can be operated on a net currently) of various systems in current and further. A network management monitoring system is arranged inside the signal monitoring device, so that detected information can be reported to a network management system of a service provider in real time, and the signal monitoring device helps the service provider to monitor the network operation condition in real time. The signal monitoring device has the advantages of being relatively low in cost, suitable for large-area popularization, and capable of bringing considerable economical benefits to the service provider.

Description

technical field [0001] The invention relates to a signal monitoring device and method for a mobile communication system. Background technique [0002] In April 2011, the network department of China Mobile Group convened manufacturers to give lectures on China Mobile's network problems and network rectification, and required all manufacturers to actively cooperate with China Mobile to take measures to improve network quality. Action" and "Deep Cultivation Action" for the indoor distribution system are both important parts of this action. [0003] In mid-April 2012, China Mobile Group once again held a mobile network work conference. Based on the content and implementation of last year's conference, the conference focused on the "three highs" issues (high configuration base stations, high height base stations, high direct Station ratio), indoor distribution quality issues, device and antenna quality issues, acceptance issues, etc., involving many network optimization equipmen...
