Detailed Description

An LAC is an area set for paging in a mobile communication system, which covers a geographical area. To determine the location of a mobile station, the coverage area of each gsm plmn is divided into a number of location areas, and Location Area Codes (LACs) are used to identify the different location areas, a location area may contain one or more cells.

Based on an analysis of base station related data of the mobile network, it is found that a Location Area Code (LAC) can be used to identify whether the device is moving a large distance and does not generate additional power consumption.

The child positioning watch is close to a mobile phone in terms of scheme, and is a device for transmitting data based on a mobile network. The mobile base station information of the mobile network can be obtained without additional power consumption when the watch registers the mobile network.

Fig. 1 is a schematic flow chart of a method for determining large-distance movement of a device position applied to a positioning watch according to an embodiment of the application. The method for judging the large-distance movement of the equipment position comprises the following steps: and judging whether the position of the equipment moves in a large distance according to the change condition of the LAC number. The method specifically comprises the following steps:

pre-establishing an LAC list and setting a threshold;

initialization step S1: acquiring a reference position, clearing an LAC list, reading an LAC number in current base station information, and adding the LAC number into the LAC list, wherein at the moment, only one LAC number is in the LAC list; the reference position is acquired to send the reference position to a GNSS positioning chip of the MT3333, so as to improve positioning efficiency;

LAC list update step S2: continuously monitoring the change condition of the LAC in the base station information, comparing the changed LAC numbers with the LAC numbers in an LAC list one by one when the LAC is changed, if the changed LAC numbers are different from all the LAC numbers in the LAC list, considering the changed LAC as a new LAC, and then adding the new LAC number into the LAC list;

distance determination step S3: when the number of the LAC numbers in the LAC list reaches a preset threshold value, the position of the equipment is considered to move in a large distance, and then the initialization step is returned;

at the boundary between the coverage areas of two adjacent LACs, it is easy to see that the device location has not changed, but two LACs can be observed, so the optimal value of the threshold in the distance determination step S3 is 3, that is, when the number of LACs in the LAC list reaches 3, it is considered that the device location has moved a large distance, and it is necessary to reacquire the reference location.

LAC list update submodule 2: continuously monitoring the change condition of the LAC in the base station information, comparing the changed LAC numbers with the LAC numbers in an LAC list one by one when the LAC is changed, if the changed LAC numbers are different from all the LAC numbers in the LAC list, considering the changed LAC as a new LAC, and then adding the new LAC number into the LAC list;
