1 Scope
The present document is an introduction to the TSG RAN TS 25.45z series of UMTS Technical Specifications that
define the Iupc Interface. The Iupc interface is a logical interface for the interconnection of Stand-Alone SMLC (SAS)
and Radio Network Controller (RNC) components of the Universal Terrestrial Radio Access Network (UTRAN) for the
UMTS system.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Stand-Alone SMLC (SAS): As defined in [11].
RNC Centric: In this mode of operation (defined in [11]), the RNC is responsible for position method selection and
initiation of the selected positioning method. Once a position method is selected, the RNC may interact with the SAS to
exchange data as well as for execution of the selected positioning method.

SAS Centric: In this mode of operation (defined in [11]), the SAS is responsible for position method selection and
initiation of the selected positioning method. Once a position method is selected, the SAS may interact with the RNC to
exchange data to enable it to execute the selected positioning method.
