TS 123 171-2001 Universal Mobile Telecommunications System (UMTS); Functional Stage 2 Description of Location Services in UMTS (3GPP TS 23.171 Version 3.6.0 Release 1999)
The present document specifies 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 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 technology 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.
