Embodiment Construction
[0028] A mobile communication network air interface monitoring system based on software radio technology, such as figure 1 As shown, it is mainly composed of at least one signal collector, a signal processing unit, a signaling analysis unit and a system control unit. Both the signal collector and the signal processing module are included in the general software radio platform. The signaling analysis unit and the system control unit can be local servers, headquarters or servers in the cloud. The output end of the signal collector is connected to the input end of the signal processing unit, the output end of the signal processing unit is connected to the input end of the signaling analysis unit, and the system control unit is connected to the signal processing unit and the signaling analysis unit.
[0029] When the mobile equipment device communicates wirelessly with the base station, access point or other mobile devices, the signal collector receives the air interface signal, ...

The invention discloses a mobile communication network air interface monitoring system. A signal collector receives an air interface signal, configures information according to channels of a community to be monitored and selects the method of narrow-band sampling or wide-band sampling to conduct preliminary quantization to the air interface signal; a signal processing unit receives data obtained after the preliminary quantization, selects different digital signal processing functions to demodulate the data obtained after the preliminary quantization according to the difference among network types of the community to be monitored and outputs component channel data of a single physical channel or multiple physical channels; after receiving the component channel data, a signaling analysis unit selects a processing module in the program according to the network structure of the community to be monitored, conducts processing to the data and outputs a signaling report transmitted in a logical channel; a system control unit conducts control and monitoring to the whole system in a local or a remote way. According to the system, through the combination between a software radio platform and a general-purpose computer, analysis can be conducted to signaling in upstream communication and downstream communication of a mobile communication network air interface.
Description
technical field [0001] The invention belongs to the technical field of mobile communication networks, and in particular relates to a mobile communication network air interface monitoring system based on software radio technology. Background technique [0002] The mobile communication network is the basis for mobile operators to operate. The operating efficiency and the income brought to the operator ultimately depend on the coverage area of the network, the capacity of the network system, and the quality of service. The most important part is the wireless network interface. The air interface of the mobile communication network system is the most important interface in the mobile communication network system. In the operation of the mobile communication network system, the air interface, as the wireless interface for communication between the mobile terminal and the base station, is easily affected by various factors, and there are many factors that induce instability. The...
