23.1013GPPGeneral Universal Mobile Telecommunications System (UMTS) architectureRelease 17TS

The general UMTS architecture is modelled, at a high level, from both physical and functional viewpoints. The physical aspects are modelled using the domain concept and the functional aspects are modelled using the strata concept.

The two views are introduced separately and then the mapping between the views is discussed.

This specification shows at a basic level physical and functional separations to allow a UMTS network to fit within the context of the IMT-2000 family of networks. It does not attempt to develop aspects of a UMTS network that are highly specific to that implementation.
