The present document defines the stage 3 network protocol description to the 3GPP Generic User Profile (GUP)@ which includes the elements necessary to realise the stage 2 requirements in 3GPP TS 23.240 [1]. The fact of having several domains within the 3GPP mobile system (e.g. Circuit-Switched@ Packet-Switched@ IP Multimedia Subsystem) and access technologies (e.g. GERAN@ UTRAN and WLAN) introduces a wide distribution of data associated with the user. Further@ the new functions both in terminals and networks mean that the data related to users@ services and user equipment will be increased greatly. This causes difficulties for users@ subscribers@ network operators and value added service providers to create@ access and manage the user-related data located in different entities. The objective of specifying the 3GPP Generic User Profile is to provide a conceptual description to enable harmonised usage of the user-related information located in different entities. Technically the 3GPP Generic User Profile provides an architecture@ data description and interface with mechanisms to handle the data.
