Periodical-triggering positioning method

Abstract

The method adds periodic positioning authorization message in private setting information of object SET. After receiving message for requesting periodic positioning sent from SUPL proxy, H-SLP finds out periodic positioning authorization message in private setting information of object SET, and then carries out subsequent periodic positioning procedure based on the authorization message. The invention raises periodic positioning efficiency, and provides multiple informing positioning modes for object SET. Thus, the object SET can cancel this periodic positioning in procedure for periodic positioning. Further, H-SLP can send periodic positioning detailed information to object SET to let object SET allow or refuse positioning procedure based on the said detailed information so as to widen application area of positioning service.

Description

technical field [0001] The invention relates to the technical field of location services, in particular to a periodic trigger positioning method. Background technique [0002] At present, in the location service technical specification developed by the International Open Mobile Alliance (OMA, Open Mobile Alliance), the periodic positioning system for realizing the location service is defined. The location service cycle positioning system can work in two modes: the mode based on server trigger and the mode based on terminal trigger. In the server-based triggering mode, the positioning server in the system sends an immediate positioning notification to the target terminal at intervals within a certain period of time according to its own periodic positioning tasks, and passes the immediate positioning notification after obtaining the consent of the target terminal. The process obtains the current location of the target terminal; in the terminal-based trigger mode, the position...

Problems solved by technology

[0023] It can be seen from the above that after the H-SLP receives the TLRR message indicating periodic positioning sent by the SUPL agent, if it inquires the privacy setting information of the target SET and requires a positioning notification, the H-SLP will initiate positioning to the target SET every time. , all need to be notified to the target SET, especially when the confirmation of the target SET is required, each positioning needs to wait for the confirmation of the target SET, and in some cases, the target SET may wish to perform a one-time confirmation of this periodic positioning , and do not want to repeat the confirmation, so the existing periodic trigger positioning may increase the positioning time and reduce the positioning efficiency

In addition, H-SLP does not inform the target SET that the current positioning is periodic, that is, the target SET does not know that the current process is periodic positioning, and in practical applications, the target SET may also need information about periodic positioning To decide whether to allow the current positioning, for example: if the target SET can tolerate the periodic positioning time interval of 15 minutes, and the current periodic positioning time interval is less than 15 minutes, then the target SET will reject this periodic positioning, but the existing technology does not give a solution to this
