Abstract: In a method for providing Location Based Services (LBS) in a mobile communication system, upon receipt of a location trigger at an LS for requesting location information of an MS from a location client, the LS transmits an authentication request message for requesting an ID of an Anchor Authenticator (AA) for the MS to an Authorization, Authentication and Accounting server (AAA), which transmits an authentication response message to the LS. The LS transmits an LCID request message for requesting an LCID of an LC for the MS to the AA, which AA transmits an initiate MS paging request message to an APC. The APC detects a serving LC of the MS and transmits an LCID to the AA, which transmits an LCID response message to the LS, which transmits an MS location report request message to the serving LC. The LC transmits an MS location report response message to the LS.
