Abstract

The present application discloses a method and a device for judging the position of equipment moving over a large distance. The method judges whether the location of the device has moved over a large distance according to the change of the LAC number, and specifically includes: an initialization step: obtaining a reference location, clearing the LAC list, obtaining the current location, and adding the LAC number of the current location to the In the LAC list; LAC list update step: continue to observe the LAC number, when a new LAC number occurs, add the new LAC number to the LAC list; distance judgment step: when the LAC list When the number of LAC numbers in reaches the preset threshold, it is considered that the position of the device has moved a large distance, and then returns to the initialization step. The device includes an initialization submodule, an LAC list updating submodule and a distance judging submodule.

Description

technical field

[0001] This application relates to the positioning technology of children's watches, in particular to a method and device for judging the position of a device moving over a large distance. Background technique

[0002] In recent years, children's wearable devices have developed rapidly, especially positioning children's watches with GNSS. In order to shorten the positioning time, the conventional method is to inject a reference position (approximate position within 30km near the actual position), such as MTK's MT3333 solution. However, obtaining the reference position through networking will bring additional power consumption. In order to reduce the number of networking times, a method is needed that can transmit data without connecting to the server, and obtain whether the device is moving over a large distance without GNSS and other means. Contents of the invention

[0003] It is an object of the present application to overcome the above-mentioned proble...

Examples

Embodiment Construction

[0029] The LAC is an area set up for paging in the mobile communication system, and this area covers a geographical area. In order to determine the location of the mobile station, the coverage area of ​​each GSMPLMN is divided into many location areas, and the location area code (LAC) is used to identify different location areas. A location area can contain one or more cells.

[0030] Based on the analysis of the relevant data of the base station of the mobile network, it is found that a location area code (LAC: location area code) can be used to identify whether a device moves over a large distance without generating additional power consumption.

[0031] The children's positioning watch is very close to the mobile phone in terms of scheme, and it is a device that transmits data based on the mobile network. When the watch is registered on the mobile network, the mobile base station information of the mobile network can be obtained without additional power consumption.
