At present many of these applications are not possible to predict. Also the usage of the different applications are diffic
23、ult to predict i.e. it is not possible to optimise UMTS to only one set of applications. One conclusion of this is that UMTS must be built in such a way that it is flexible and possible to evolve so it will have a long technical lifetime. Therefore a modular approach is recommended when defining the
24、 network parts of UMTS. This is in line with the recommendation from GMM. In this context a module represents a part of a UMTS network i.e. one or several physical network nodes that together implements some functionality. The modular approach should also make UMTS possible to implement efficiently
25、in different environments. ETSI ETSI TS 123 101 V15.0.0 (2018-06)53GPP TS 23.101 version 15.0.0 Release 151 Scope This TS defines the basic physical and functional separation of UMTS. The contents of this specification is limited to those features that are common to all UMTS networks independent of
26、their origin. It identifies and names the reference points and functional groupings appearing at this level. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by d

33、. 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
34、 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. 5 Domains in UMTS The following figure shows the basic domains in UMTS as described in this section. User Equi
35、pment Domain Access Network Domain Core Network Domain Infrastructure Domain Cu Mobile Equipment Domain USIM Domain Home Network Domain Transit Network Domain Uu Iu Zu Yu Serving Network Domain NOTE : The domains identified in the figure will generally result from an evolution of existing network in
36、frastructures. The core network domain may result from evolutions of existing network infrastructures, e.g., a GSM infrastructure, a N-ISDN infrastructure, a B-ISDN infrastructure or a PDN infrastructure. The evolution of these infrastructures may be performed via the use of IWUs, hidden within the
37、domains shown in the figure.

This results
39、 in two domains: the User Equipment Domain and the Infrastructure domain. User equipment is the equipment used by the user to access UMTS services. User equipment has a radio interface to the infrastructure. The infrastructure consists of the physical nodes which perform the various functions requir
40、ed to terminate the radio interface and to support the telecommunication services requirements of the users. The infrastructure is a shared resource that provides services to all authorised end users within its coverage area. The reference point between the user equipment domain and the infrastructu
41、re domain is termed the “Uu“ reference point (UMTS radio interface). NOTE: The description assumes an access interface based on UTRA. However, the physical and functional separation described in this document is general and is applicable also if other access technologies are used. 5.2 User equipment
42、 Domain This domain encompasses a variety of equipment types with different levels of functionality. These equipment types are referred to as user equipment (terminals), and they may also be compatible with one or more existing access (fixed or radio) interfaces e.g. dual mode UMTS-GSM user equipmen
43、t. The user equipment may include a removable smart card that may be used in different user equipment types. The user equipment is further sub-divided in to the Mobile Equipment Domain (ME) and the User Services Identity Module Domain (USIM). The reference point between the ME and the USIM is termed
44、 the “Cu“ reference point. For the purpose of UMTS Cellular networks the following definition applies: User Equipment is a device allowing a user access to network services. For the purpose of 3GPP specifications the interface between the UE and the network is the radio interface. A User Equipment c
45、an be subdivided into a number of domains, the domains being separated by reference points. Currently defined domains are the USIM and ME Domains. The ME Domain can further be subdivided into several components showing the connectivity between multiple functional groups. These groups can be implemen
46、ted in one or more hardware devices. An example of such a connectivity is the TE MT interface. Further, an occurrence of User Equipment is an MS for GSM as defined in TS 24.002 3.

The names within brackets are just provided
48、to map the functional blocks from the figure above onto physical elements.
