<p>A method for providing a location value of a target SET of a location information providing system is provided to allow location calculation to be performed within a determined period. An H-SLP(Home-SUPL Location Platform) and a target SET exchange an SUPL(Secure user Plane Location) INIT message and an SUPL TRIGGERED START message, and the target SET obtains a positioning method and conditions of a periodical positioning service to start a periodical positioning service. The H-SLP checks whether an SUPL INIT message for initiating positioning has been received from the target SET. When the SUPL INIT message has not been received, the H-SLP transmits a triggered message for initiating positioning to the target SET. The target SET receives the triggered message and transmits the periodical positioning initiation message to the H-SLP. The H-SLP and the target SET perform positioning. The H-SLP transmits the positioning value to an SUPL agent.</p> |
