ETSI ETSI TS 123 171 V3.11.0 (2004-03) 7 3GPP TS 23.171 version 3.11.0 Release 1999 1 Scope The present document specifies
37、 the stage 2 of the LoCation Services (LCS) feature in UMTS, which provides the mechanisms to support mobile location services for operators, subscribers and third party service providers. Location Services may be considered as a network provided enabling technology consisting of standardised servic
38、e 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 technology are outside the scope of the present document. However, clarifying
39、examples of how the functionality being described may be used to provide specific location services may be included. This stage 2 service description covers the LCS system functional model for the whole system, the LCS system architecture, state descriptions, message flows, etc. 2 References The fol
40、lowing documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not ap

In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 2.1 Normative references 1 3G TR 25.
