Claim:
A method for processing location information request initiated by a User Equipment (UE), comprising: receiving, by a Central Network (CN), a request for location information from a target UE, and the CN obtaining a location estimate of the target UE; sending, by the CN, the location estimate of the target UE to a Gateway Mobile Location Center (GMLC) of the target UE; receiving, by the CN, a requester identifier from the target UE; providing, by the CN, the GMLC with the requester identifier so that the GMLC sends the location estimate of the target UE to the requester; wherein the GMLC sends the location estimate of the target UE to the requester comprises: the GMLC determining whether the GMLC can directly access the requester according to the requester identifier, if the GMLC can directly access the requester according to the requester identifier, the GMLC directly sending the location estimate of the target UE to the requester; and receiving, by the CN, a second response for the location estimate of the target UE from the GMLC after the requester returns a first response for the location estimate of the target UE to the GMLC; if the GMLC cannot directly access the requester according to the requester identifier, according to the requester identifier, the GMLC determining a second GMLC that can directly access the requester, and sending the location estimate of the target UE to the requester through the second GMLC; receiving, by the second GMLC, a first response for the location estimate of the target UE from the requester; returning, by the second GMLC, a second response for the location estimate of the target UE to the GMLC, and returning, by the GMLC, a third response for the location estimate of the target UE to the CN; and sending, by the CN, the location estimate of the target UE to the target UE.
