45、059 version 13.1.0 Release 131 Scope The present document specifies the stage 2 of the LoCation Services (LCS) feature in GERAN, which provides the mechanisms to support mobile location services for operators, subscribers and third party service providers. The purpose of this stage 2 specification i

46、s to define the GERAN LCS architecture, functional entities and operations to support location methods. This description is confined to the aspects of LCS within the GERAN and does not define nor describe the LCS entities or operations within the Core Network. Location Services may be considered as

47、a network provided enabling technology consisting of standardised service capabilities, which enable the provision of location applications. The application(s) may be service provider specific. The description of the numerous and varied possible location applications which are enabled by this techno

48、logy are outside the scope of the present document. However, clarifying examples of how the functionality being described may be used to provide specific location services may be included. This stage 2 specification covers the GERAN LCS functional model and entities, the location methods, state desc

49、riptions, and message flows. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
