Method for obtaining positioning result for SUPL positioning platform

Abstract

The key points of the method include following procedures: response message of position request returned from SLP to target SET contains indication information of returned positioning result; after receiving response of position request from SLP, and determining indication of returned positioning result in the response, target SET returns positioning result back to SLP. Using the invention makes SLP obtain final positioned result under condition of positioned SET-Based. Thus, the invention prevents that charging record of SLP still considers it is a successful positioning operation even if positioning operation by SET is failed so that SLP can take different charging strategy based on whether user obtains positioned result. Moreover, SLP can pass the positioned result to third party. SLP can buffer the positioned result of the target SET. Thus, in subsequent, possible other positioning the target terminal, the positioning result of satisfying QoS of positioning request can be provided rapidly.

Description

technical field [0001] The present invention relates to the field of mobile location services, in particular to a method for obtaining a positioning result based on a Secure User Plane Location (SUPL, Secure User Plane Location) positioning platform. Background technique [0002] The general process of the current security-based positioning method is as follows: when a client initiates positioning of a target terminal through a mobile location service (MLS, Mobile Location Services) application residing on it, the SUPL Location Platform (SLP, SUPL Location Platform) ) notifies the target terminal to start positioning, completes the position calculation of the target terminal through the precise positioning session between the target terminal and the SLP, and the SLP notifies the MLS client of the calculation result to complete the entire positioning process. This process belongs to the network-initiated real-time positioning process Correspondingly, when the SUPL terminal (S...

Problems solved by technology

[0036] When the SET-Based positioning method is used and the positioning is initiated by the SET, the SET can calculate the positioning result by itself based on the positioning assistance data sent by the SLP. At this time, the SLP in the prior art only serves to provide the auxiliary data. When the terminal initiates positioning and uses the SET Based positioning method, the existing technology ignores the need for the SLP to obtain the final positioning result, resulting in the fact that the SLP cannot know whether the user has actually obtained the positioning result after providing the positioning service. In the case of SET positioning failure, the SLP billing record still considers it a successful positioning operation

[0037] Moreover, the existing technology does not consider the situation where the positioning result needs to be delivered to a third party when the terminal initiates the positioning.
