Safety subscriber plane mobile positioning method

Abstract

The method expands id of request party in message of positioning request to id of capable of supporting two or more request parties. After receiving message of positioning request sent from SUPL proxy, H-SLP sends SUPL initialization message with id of request party needed to validate or inform by object SET being carried to object SET. After positioning operation is completed, the method sends obtained id of request party granted by object SET to SUPL proxy. The invention raises positioning efficiency, and saves network resources when multiple request parties need to obtain position information of object SET simultaneously.

Description

technical field [0001] The invention relates to the field of user plane mobile location services, in particular to a security-based user plane mobile positioning method initiated by a network. Background technique [0002] Currently, the International Open Mobile Alliance (OMA, Open Mobile Alliance) has formulated a positioning process for a SUPL Terminal (SET, SUPL Enabled Terminal) in its Secure User Plane Location (SUPL, Secure User Plane Location) protocol. Among them, in the location process initiated by the network, the mobile location service (MLS, Mobile LocationService) application on the network side sends a location request to the target SET by a requesting party to the SUPL location platform (SLP, SUPL LocationPlatform) through the SUPL agent, and then The SLP performs relevant authentication on the requester according to the privacy setting of the target SET, and sends the location information of the target SET obtained during the positioning process to the requ...

Problems solved by technology

[0022] As mentioned above, in the current SUPL protocol, the requester is the only one, but in practical applications, there are often situations where multiple requesters need to obtain the location information of the same target SET at the same time. At this time, the multiple requesters There are two ways to obtain the authorization of the same target SET: one is that the multiple requesters initiate a positioning request in the name of one of the requesters and require the authentication of the target SET, and after obtaining the authorization of the target SET and receiving the SLP send After receiving the location information of the target SET, the requester that initiates the positioning request forwards the location information of the target SET to other requesters. It can be seen that there must be a prerequisite for this situation: the authentication results of the target SET for all requesters must be The same, but in practical applications, the target SET usually has different authentication results for the requester that needs to obtain its own location information; the other is that the multiple requesters initiate location requests separately and require the authentication of the target SET one by one, In this case, each requester needs to initiate a positioning request, which will reduce the positioning efficiency and waste network resources
