Problems solved by technology

However, if the target terminal itself cannot perform time synchronization, and DMS is not configured in the system, or the version of DMS configured in the system is too low to have the time synchronization function, the time between the H-SLP and the target terminal will be out of sync. The problem

Embodiment Construction

[0036] The core idea of ​​the present invention is to use the interactive messages between the H-SLP and the target terminal in the periodic positioning service specified by the SUPL protocol to complete the time synchronization between the H-SLP and the target terminal

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The following embodiments all aim at the situation where the target terminal agrees to perform periodic trigger positioning in step 105 .

[0039] Please refer to figure 2 , figure 2 It is a flow chart of Embodiment 1 of the method for periodic positioning of a mobile terminal provided by the present invention.

[0040] In this embodiment, the time synchronization between the H-SLP and the target terminal is when the target terminal is connected to the data ne...

Abstract

The invention discloses a method for periodic positioning of a mobile terminal. The method includes: step A, the positioning initiating client requests the home positioning platform H-SLP to perform periodic trigger positioning on the target terminal, and the H-SLP notifies the target terminal that periodic triggering is required Positioning; step B, the H-SLP and the target terminal use the messages used in the positioning process of the secure user plane-based mobile positioning SUPL protocol to perform time synchronization; step C, the H-SLP interacts with the target terminal to obtain the position of the target terminal, and locates The result is sent to the positioning initiating client. By adopting the technical solution provided by the present invention, the synchronization between H-SLP and the target terminal can be realized in the periodic positioning service by relying on the SUPL protocol itself, without relying on special network types or special network equipment, so that there is no need to update existing Some networks implement periodic positioning services through any transformation.

Description

technical field [0001] The invention relates to a mobile positioning technology, in particular to a method for periodic positioning of a mobile terminal. Background technique [0002] In the field of mobile positioning, the International Open Mobile Alliance (OMA, Open Mobile Alliance) has comprehensively regulated mobile positioning services in its secure user plane-based mobile positioning (SUPL, Secure User Plane Location) protocol. [0003] In some applications, the positioning initiating client needs to periodically locate the target terminal. In order to realize this type of application, in the prior art, the typical interaction steps between the location initiation client, the home SUPL location platform (H-SLP, Home SUPL Location Platform) and the target terminal are as follows: figure 1 shown. [0004] Step 101, the positioning initiating client proposes a Mobile Location Protocol Triggered Location Reporting Request (MLP TRRR, Mobile Location Protocol Triggered L...
