48、ines the stage-2 service description for the LoCation Services (LCS) feature on GSM, which provides the mechanisms to support mobile location services of operators, which are not covered by standardized GSM services. CCITT I.130 4 describes a three-stage method for characterization of telecommunicat

49、ion services, and CCITT Q.65 5defines stage 2 of the method. The LCS feature is a network feature and not a supplementary service. This version of the stage 2 service description covers aspects of LCS e.g., the functional model, architecture, positioning methods, message flows etc. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
