Embodiment

[0063] Embodiment: Utilize Xi'an City PHS (Little Smart) network to carry out vehicle alarm experiment

[0064] ●The upper limit of the number of base stations participating in the calculation is the 5 base stations with the strongest field strength.

[0065] ●The threshold parameter of autonomous positioning algorithm is set to 60.

[0066] ●The value of terminal timing detection period is 1 minute.

[0067] Situation 1: The signal coverage of the base station in the environment where the terminal equipment is located is good, the terminal stays there for 30 minutes, and the control center does not receive the terminal location change alarm information. Extract the data held in the terminal, as shown in the table below:

[0068] Table 1: Base station and field strength data

[0069]

[0070] (The base station installation location information is a secret of the telecom operator, and the public data changes the CSID number of the base station.) It can be determine...

Abstract

The invention relates to one method to judge whether the mobile communication terminal position change based on station in wireless communication technique field, which comprises the following steps: through use of terminal timer to test its surrounding codes and relative field intensity data; then using current time to get base station data and front time base data; computing each base station field change different sum F to compare with valve values; if F is larger than valve values, expressing terminal position changes to send position alarm information to control center; otherwise, expressing terminal position changes not to send control center information.

Description

Technical field: [0001] The invention relates to the technical field of wireless communication, in particular to a method for judging whether the position of a mobile communication terminal changes based on a base station. Background technique: [0002] With the increase in the number of motor vehicles, the demand for motor vehicle anti-theft and tracking technologies is becoming more and more extensive. By installing a positioning device on the motor vehicle and using positioning technology to monitor the position of the motor vehicle, the problem of anti-theft and tracking of the motor vehicle can be effectively solved. How to quickly and accurately judge whether the motor vehicle is moving is the core technology of this type of motor vehicle anti-theft scheme. At present, there are mainly two methods for determining the location of a motor vehicle: [0003] 1. Install GPS positioning devices on motor vehicles, use GPS to obtain location information, and use other commun...
