Paging black hole cell locating method based on signaling of interface A

Abstract

The invention discloses a paging black hole cell locating method based on a signaling of an interface A, which comprises the steps of: at first, acquiring the signaling of the interface A in a GSM (Global System for Mobile communication) network, performing collection, decoding and correlation analysis via a server to generate a call detail record (CDR), and adding the CDR to a signaling database; then performing correlation analysis on signaling information in the signaling database to obtain a statistical analysis result, and sorting out paging black hole cells according to the statistical analysis result in order to obtain a list of the paging black hole cells; and finally locating the position and distribution of the paging black hole cells according to the list of the paging black hole cells. In the method, the condition of paging black holes in a network and cells in which paging failure occurs specifically are counted through the analysis based on relevant signaling data information of the interface A, thus operators can be aware of the condition of mobile communication network in time, and rapid positioning of network optimization personnel is facilitated so as to enhance optimization efficiency.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for positioning a paging black hole cell based on A interface signaling in a GSM network. Background technique [0002] The process of wireless paging, that is, the communication process in which MSC (Mobile services Switching Center) finds the mobile station MS through paging. Only after the mobile user is found, the MSC can carry out the next call connection work. In the GSM mobile communication system, the basic signaling process of wireless paging is as follows: when the MSC obtains the location area (LAC) where the mobile station MS is currently located from the VLR (Visitor Location Register), it will send a message to this location area. All BSCs (BaseStation Controllers) of the base station send a paging message (Paging), and after receiving the paging message, the BSC sends a paging command message (Paging Command) to all cells belonging to the location area ...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, the paging performance can be analyzed by querying the paging statistics, but the traditional paging statistics can only target the hardware at the LAC and MSC level, and cannot be specifically located at the cell level. The treatment can only stay on the surface and cannot solve specific problems

It is also possible to locate the paging problem by performing a large number of DT (Drive Test) and CQT (Call Quality Test) calling and calling tests, but this method is inefficient and vulnerable to mobile terminals and testers. The influence of subjective conditions

So there is no good paging black hole cell positioning method
