45、14.0.0 Release 141 Scope The present document specifies the stage 2 of the UE Positioning function of UTRAN, which provides the mechanisms to support the calculation of the geographical position of a UE. UE position knowledge can be used for example in support of Radio Resource Management functions,
46、 location-based services for operators, subscribers and third party service providers. The purpose of this stage 2 specification is to define the UTRAN UE Positioning architecture, functional entities and operations to support positioning methods. This description is confined to the UTRAN Access Str
47、atum. It does not define nor describe how the results of the UE position calculation can be utilised in the Core Network (e.g. LCS) or in UTRAN (e.g. RRM). UE Positioning may be considered as a network provided enabling technology consisting of standardised service capabilities, which enable the pro
48、vision 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 be
49、ing described may be used to provide specific location services may be included. This stage 2 specification covers the UTRAN positioning methods, state descriptions, and message flows to support UE Positioning. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
