Method for determining location of UE by using AGPS information
First Claim
1. A method for determining a location of a User Equipment (UE) by means of Assisted Global Positioning System (AGPS) information, the method comprising the steps of:
- generating, by an SUPL Location Center (SLC), a pseudo UE ID according to a request for location information of the UE, the pseudo UE ID being used for maintaining security during communication with an SUPL Positioning Center (SPC);
requesting AGPS information for the UE, the location information of which has been requested, to the SPC by means of the pseudo UE ID, and receiving the AGPS information;
transferring the received AGPS information to the UE, and receiving Global Positioning System (GPS) signal measurement values using the AGPS information from the UE;
requesting a location calculation of the UE for the GPS signal measurement values to the SPC by means of the pseudo UE ID, and receiving calculated location values; and
providing the location information of the UE by means of the received location values of the UE.
