Abstract

The disclosure provides a positioning service method and system, and a terminal. In the above method, a positioned terminal receives a movement track model established by a positioning service platform; the positioned terminal judges whether or not positioning data that are collected satisfy the movement track model; and when the positioning data satisfy the movement track model, it is determined that there is no need to report the positioning data, and when the positioning data do not satisfy the movement track model, the positioning data are reported to the positioning service platform. The technical solution provided by the disclosure can reduce the frequency for the positioned terminal to report the positioning data and also save network data traffic for the user.

3. The method according to claim 2, wherein the movement track model comprises:

a coordinate location, a time point, a location threshold range, and a time threshold range;

judging whether or not the positioning data that are collected satisfy the coordinate location condition comprises;

judging whether or not a coordinate location in the positioning data is within an allowed range specified by the location threshold range and the coordinate location of as key location in the movement track model; and

judging whether or not the positioning data that are collected satisfy the time point condition comprises;

judging whether or not a collection time point of the positioning data is within an allowed range specified by the time threshold range and the time point of a key location in the movement track model.

4. The method according to claim 1, wherein before the positioned terminal collects the positioning data, the method further comprises:

when a subscriber identity module tool kit (STK) service module of the positioned terminal is initialized, receiving device capability information from the positioned terminal; and

the STK service module judging whether or not the positioned terminal has a global positioning system (GPS) positioning function according to the device capability information.

5. The method according to claim 4, wherein after the STK service module judges whether or not the positioned terminal has the GPS positioning function according to the device capability information, the method further comprises:

if the positioned terminal has the GPS positioning function, the STK service module notifying the positioned terminal to collect the positioning data, and the positioned terminal performing the GPS positioning function to collect the positioning data, and if the collection has failed, the positioned terminal performing a low precision positioning function according to a cell identity to collect the positioning data; and

if the positioned terminal does not have the GPS positioning function, the positioned terminal performing the low precision positioning function to collect the positioning data.

6. The method as claimed in claim 1, further comprising:

the positioning service platform determining whether or not to adjust a positioning mode of the positioned terminal according to a distance between a positioning initiation terminal and the positioned terminal, wherein the positioning mode comprises;

a silence mode and an activated positioning mode.

7. The method according to claim 6, wherein the positioning service platform determining whether or not to adjust the positioning mode of the positioned terminal according to the distance between the positioning initiation terminal and the positioned terminal comprises:

the positioning service platform judging, according to network side data, whether or not a cell identity of a mobile network to which the positioning initiation terminal registers and a cell identity of a mobile network to which the positioned terminal registers are identical;

if the cell identity of the mobile, network to which the positioning initiation terminal registers and the cell identity of the mobile network to which the positioned terminal registers are identical, then the positioning service platform determining that the distance between the positioning initiation terminal and the positioned terminal is less than a preset threshold, and issuing an instruction to adjust the positioning mode of the positioned terminal as the silence mode;

when a cell identity of a network where the positioning initiation terminal or the positioned terminal resides changes, the positioning service platform judging whether or not there is a need to adjust the positioning mode of the positioned terminal as the activated positioning mode.

8. The method according to claim 7, wherein when both the positioning initiation terminal and the positioned terminal have a GPS positioning function, the positioning service platform judging whether or not there is the need to adjust the positioning mode of the positioned terminal as the activated positioning mode comprises:
