THE MECHANISM OF USING PSEUDO-ID OF THE TARGET SECURE USER PLANE LOCATION(SUPL) ENABLED TERMINAL IN THE OPEN INTERFACE OF LOCATION MANAGEMENT AND LOCATION CALCULATION FUNCTION

摘要

A method for calculating a location of a target terminal for protecting privacy of a user of the target terminal is provided to calculate a location value of a target terminal roamed without transferring a real ID of the target terminal. H-SLC(Home-SUPL(Secure user Plane Location) Location Center)(303) generates a virtual ID of a target set(307) and transmits a location value calculation request message including the virtual ID to an H-SPC(Home-SUPL Positioning Center)(305). The H-SLC(303) adds the virtual ID in a message for starting calculation of a location value and transmits the same to the target set(307). The target set(307) adds the virtual ID instead of its real ID and transmits the message for starting calculation of a location value to the H-SLC(303). The H-SLC(303) transmits the message including the virtual ID to the H-SPC(305). The target set(307) and the H-SPC(305) discriminate the target set by using the virtual ID and calculate a location value of the target set(307). The H-SLC(303) transmits the calculated location value to a location value requestor of the target set(307).
