Analytical method of data traffic neighborhood ping-pong reselection

Abstract

The invention discloses an analytical method of data traffic neighborhood ping-pong reselection, and belongs to the field of mobile communications. The analytical method comprises the following steps: collecting original signaling of a gigabyte (Gb) port of a general packet radio service (GPRS) network, analyzing the collected original signaling; judging whether the ping-pong reselection occurs in a neighborhood according to the result of signaling analysis, and determining a main covering neighborhood of the ping-pong reselection. Through acquisition and analysis of the signaling of the Gb port, the phenomenon of the neighborhood ping-pong reselection occurring in the data traffic using process of users is judged and analyzed by combining a certain algorithm, and thereby analysis of the influence of the neighborhood ping-pong reselection on all data traffic users in the range of a whole network is achieved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an analysis method for ping-pong reselection of a data service cell. Background technique [0002] Issues such as network planning, wireless coverage, and cell reselection parameter settings may cause users to frequently undergo cell reselection or ping-pong reselection in a certain area of ​​the network. However, the cell ping-pong reselection that occurs during the user's use of the data service will interrupt the user's data transmission, and the user's download rate will drop sharply. In serious cases, it will cause user complaints. Therefore, how to reduce cell ping-pong reselection in the network is one of the main contents of wireless network optimization. [0003] At present, the analysis of the cell ping-pong reselection problem is mainly completed through active testing. The field strength of the main coverage cell, the carrier-to-interference ratio, the field stren...

AI Technical Summary

Problems solved by technology

[0005] 1. Active testing covers a limited range of networks, which is restricted by objective conditions such as the number of test equipment and human resources, making it impossible to conduct network-wide analysis, and the test results are somewhat random

[0006] 2. Most of the cell ping-pong reselection in the current network occurs in the idle mode of the mobile phone (that is, the user does not use the data service when the ping-pong reselection occurs), but the ping-pong reselection in these idle modes will not affect the user experience of the data service. Any impact, the active test cannot analyze the cell ping-pong reselection that occurs during the use of data services by users on the entire network, so it is impossible to determine which ping-pong reselection will have an impact on user perception

[0007] 3. Existing methods only consider the case of 1-to-1 cell ping-pong reselection, that is, frequent reselection between 1 source cell and 1 destination cell , but does not consider the ping-pong reselection between multiple cells, that is, the situation of frequent reselection among several cells in a specific order

[0008] 4. The existing technology mainly determines the main coverage cell for ping-pong reselection based on information such as base station location, antenna azimuth, and cell field strength. However, this approach will inevitably lead to the situation where users reside in a certain cell and use data services. , leading to the shortage of wireless resources in the cell

This is because, in the traditional optimization method, the optimization goal for some coverage problems is often to allow users to stay in the main coverage cell with better signal quality as much as possible. Although this avoids cell ping-pong reselection, it will make the main coverage cell The number of users and business volume of the covered cell increase
