Problems solved by technology

Although this method can choose to display voice quality indicators, so as to geographically present the distribution of voice quality, it cannot compare and analyze voice quality indicators with other wireless signal parameters.
On the other hand, the voice quality is affected by various wireless signal parameters, and the inability to conduct a comparative analysis between the two means that the reason for the deterioration of the voice quality in areas with poor voice quality cannot be accurately analyzed and located.
Therefore, the existing analysis methods cannot support network maintenance and optimization personnel to find the root cause of the problem, optimize the network, and improve user perception of voice calls

Embodiment Construction

[0007] This specific embodiment adopts following technical scheme: its optimization step is: (1), according to the location information that GPS collects automatically, network wireless signal parameter and voice quality PESQ score value are simultaneously displayed on the electronic map with different symbols such as dots (2) Choose any one of the voice quality track or the network wireless signal parameter track to make a certain range of latitude and longitude offset, so that the two tracks will no longer overlap and be displayed differently. The specific method is to display the track by offsetting 3-10 pixels to the east (west) or (and) to the south (north) on the basis of the original latitude and longitude position; (3), the network wireless signal parameters can be defaulted during specific implementation Select Rxlev to display, and the user can select other parameters to display according to needs. Other parameters include Rxqual, TA, mobile terminal transmit power, f...

Abstract

The invention discloses a mobile communication voice quality optimization method based on dual-track correlation analysis, which relates to the technical field of mobile communication network optimization. It displays the voice quality index of mobile communication and one of the wireless signal parameters on the map in the form of two traces. The two tracks use the data collected by the same GPS, and one of the tracks is offset by a certain latitude and longitude to achieve the results of the two tracks being displayed differently. The wireless signal parameters to be displayed are selected by the user, and the optional network wireless signal parameters include Rxlev, Rxqual, TA, mobile terminal transmission power, frequency band of the carrier, encoding method, and signaling events. Users can change the currently displayed wireless signal parameters at any time according to analysis needs, so as to achieve the purpose of correlation and comparative analysis between voice quality indicators and multiple wireless signal parameters.

Description

Technical field: [0001] The invention belongs to the technical field of mobile communication network optimization, in particular to an optimization method related to double-trajectory correlation analysis of mobile communication voice quality. Background technique: [0002] In the prior art, the voice quality of mobile communication is characterized by technical indicators such as network bit error rate (BER) and frame error rate (FER), but these technical indicators have nothing to do with the actual voice quality that users hear when talking on a mobile phone. Feeling inconsistent. For example, the crosstalk problem, the network BER and FER indicators will not have any abnormalities, but the crosstalk is definitely not the voice of the call partner that the user wants to hear. In order to solve this problem, in recent years, China's mobile communication operators have gradually introduced the internationally accepted voice quality evaluation system - MOS, using the ITU TP...
