High-speed railway user separation method based on signaling data of A interface and Abis interface

Abstract

The invention discloses a high-speed railway user separation method based on signaling data of an A interface and an Abis interface. The method comprises the following steps of: acquiring all signaling data of the A interface and the Abis interface of a high-speed railway cell; establishing a high-speed railway resident user database, and determining high-speed railway resident users in the high-speed railway cell; acquiring call behavior characteristics of high-speed railway users which are not the resident users according to the acquired signaling data; and separating the high-speed railway users from high-speed expressway users and normal users according to the call behavior characteristics. By the method, user types such as a high-speed railway user, a resident user along a railway and a low-speed user along the railway can be effectively separated by establishing a high-speed railway user separation algorithm model, relevant functions of a high-speed railway road test simulation system can be realized according to the separated high-speed railway users, and uncertain problems of a small quantity of testing samples, high contingency and single testing terminal during the conventional high-speed railway simulation test can be effectively solved.

Description

technical field [0001] The invention relates to the field of wireless technology communication, in particular to a high-speed railway user separation method based on A port and Abis port signaling data in a high-speed railway wireless coverage scene. Background technique [0002] At present, domestic high-speed railways are developing rapidly, and high-speed railways have become an important part of railway passenger transportation. However, due to the high speed of high-speed railways, the Doppler effect is significant, the poor indicators of high-speed railways and the lack of optimization methods have greatly restricted the optimization of high-speed railway mobile communication networks. In-depth development of work. [0003] The optimization technical means of the existing high-speed railway mobile communication network is mainly to analyze the indicators of the covered high-speed railway community through traffic statistics, and then optimize the network for abnormal c...

AI Technical Summary

Problems solved by technology

The method of analyzing the indicators of the covered high-speed railway community through traffic statistics data, because the indicators of permanent users along the high-speed railway are invisible, it is not clear whether the abnormal event is caused by the high-speed railway users, and the abnormal situation of the high-speed railway will be overwhelmed by the normal situation of a large number of resident users , cannot well reflect the high-speed rail user indicators from conventional indicators

On the other hand, the method of on-site road test will have uncertain problems such as less sampling, large sporadicity, and single test terminal, and the test cost is huge, which will have a great impact on the accuracy of the assessment of the high-speed railway wireless network situation.
