Method and device for establishing wireless cell space-time database

Abstract

The invention provides a method and device for establishing a wireless cell spatio-temporal database, which relates to the communication field and is used for establishing the wireless cell spatio-temporal database. The method comprises the following steps of determining a minimum measurement vehicle number set on a line to be measured; determining wireless cell spatio-temporal data for each vehicle in the minimum set of measured vehicles; dividing the measured line into corresponding parking line, starting line and normal driving line of each station; determining a first wireless cell spatio-temporal database according to the information; acquiring travel route information of the first train; selecting spatio-temporal data corresponding to each station through which the first train passesfrom the first wireless cell spatio-temporal database; obtaining the complete spatio-temporal data of the first train by combining the spatio-temporal data corresponding to each station passing through the first train; determining the wireless cell spatio-temporal database of the line under test, so that the method for establishing the wireless cell spatio-temporal database provided by the present application can improve the efficiency of establishing the wireless cell spatio-temporal database and save the time and cost.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for establishing a space-time database of wireless cells. Background technique [0002] The wireless cell spatio-temporal database of the high-speed train trip includes the identification, wireless signal strength, time (the time interval is determined according to the sampling interval of the signaling collection instrument, generally in seconds), wireless cell identification, wireless Signal quality, speed of high-speed trains, and latitude and longitude. By collecting communication signaling and combining the wireless cell spatio-temporal database, high-speed rail users and the positioning of high-speed rail users' mobile communication perception problems can be identified. [0003] The current method of establishing the wireless cell spatio-temporal database of high-speed rail trains is that testers take the high-speed rail trains to ...

AI Technical Summary

Problems solved by technology

To establish the wireless cell spatio-temporal database of all high-speed trains passing through on a certain high-speed rail line, surveyors are required to take all high-speed trains on the high-speed rail line to establish the wireless cell spatio-temporal database of each high-speed rail respectively, resulting in a very heavy workload. huge
