Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0019] figure 1 A flow chart of a method for ping-pong switching positioning based on A interface signaling of the present invention is shown, and the method includes the following steps:

[0020] Step S11: generating a call detail record CDR and adding it to the signaling database;

[0021] Collect the signaling of the A interface in the GSM network, collect, decode, and correlate with the server to generate a call detail record CDR, and add it to the signaling database.

[0022] The A interface is defined as the communication interface between the Network Subsystem (NSS) and the Base Station Subsystem (BSS). In terms of the system, it is the interface between the mobile switching center (MSC) and the base station controller (BSC). The information transmitted by this interface includes mobile station management, base station management, mobil...

Abstract

The invention discloses a ping-pong handover positioning method based on A-interface signaling. The method comprise the following steps: firstly, acquiring A-interface signaling from a GSM (global system for mobile communication) network, generating a CDR (call detail record) through the collection, decoding and correlation analysis by virtue of a server, and adding the CDR to a signaling database; secondly, carrying out correlation analysis on the information in the signaling database so as to obtain statistic analysis results, screening out ping-pong handover cell pairs according to the results, thus obtaining a list of ping-pong handover cells; and finally, ranking the ping-pong handover cells in the list according to the generation times of ping-pong handover, and positioning the locations and areas of the ping-pong handover cells. According to the method, through the analysis on relevant signaling data information during communication, the conditions of ping-pong handover and the cells at which handover practically happens are obtained through statistics, therefore, an operator can timely get information about the conditions of a mobile communication network, the fast positioning of ping-pong handover by network optimization personnel is facilitated, and the optimization efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a ping-pong switching positioning method based on A interface signaling. Background technique [0002] With the increase in the number of mobile communication users, mobile communication operators are paying more and more attention to the satisfaction of user call quality. How to evaluate abnormal events (single call, dropped calls, etc.) It is more and more important to optimize the mobile communication network. [0003] Switching corresponds to the process in which the mobile phone abandons the original channel and accesses a new channel. During the handover process, the signaling on port A is different due to the different handover types. For intra-BSC handover (including intra-cell handover and inter-cell handover), only after the handover is completed, the BSC sends Handover Performed (handover execution) to the MSC to notify the MSC that the handover has be...
