US Patent 7623874 Method for processing requests for location

The present invention discloses a method for processing requests for location, which comprises: A target UE sending a request for location to the Location Service (LCS) system and asking the LCS system to provide a requestor with the location information of the target UE; the LCS system positioning the target UE, acquiring the location estimate of the target UE, and deciding whether it is needed to hide the real identity of the target UE, and if yes, the LCS system sending the pseudonym and location information of the target UE to the requestor; otherwise, the LCS system sending the real identity and location information of the target UE to the requestor. The invention makes it possible for the LCS system to decide whether to hide the real identity of the target UE according to the user's requirement, improving the flexibility of the location service. As the LCS system is able to hide the real identity of the target UE, the security of using the location service is enhanced.
