18、4.0.0 Release 14Foreword This Technical Specification has been produced by the 3rd Generation Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present
19、 document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change
20、 control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction UMTS will support a wide range of applications with diff
21、erent quality of service profiles. At present many of these applications are not possible to predict. Also the usage of the different applications are difficult 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 s
22、uch 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 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
23、 or several physical network nodes that together implements some functionality. The modular approach should also make UMTS possible to implement efficiently in different environments. ETSI ETSI TS 123 101 V14.0.0 (2017-05)53GPP TS 23.101 version 14.0.0 Release 141 Scope This TS defines the basic phy
24、sical and functional separation of UMTS. The contents of this specification is limited to those features that are common to all UMTS networks independent of their origin. It identifies and names the reference points and functional groupings appearing at this level. 2 References The following documen

31、t 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 s
32、hows 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. 5 Domains in UMTS The following figure shows the b
33、asic domains in UMTS as described in this section. User Equipment 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 wi
34、ll generally result from an evolution of existing network infrastructures. 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 infrastructu
35、res may be performed via the use of IWUs, hidden within the domains shown in the figure.

37、r equipment (terminals) and the infrastructure. This results 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 t
38、he physical nodes which perform the various functions required 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
39、point between the user equipment domain and the infrastructure 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 al
40、so if other access technologies are used. 5.2 User equipment 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 (fixe
41、d or radio) interfaces e.g. dual mode UMTS-GSM user equipment. 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
42、). The reference point between the ME and the USIM is termed 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 U
43、E and the network is the radio interface. A User Equipment can 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 betw
44、een multiple functional groups. These groups can be implemented 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. The figure below shows the Functional Model for the User Equip
45、ment, UE. UE MEUSIM MT TEFigure 1a: Functional Model for the User Equipment The 07- and 27-series refer to physical instances of this Functional Model. The figure below shows an example of a physical configuration as it could be used in these specifications. The boxes, in this figure, refer to physi
46、cal elements. The names within brackets are just provided to map the functional blocks from the figure above onto physical elements.

47、bile equipment Domain The Mobile Equipment performs radio transmission and contains applications. The mobile equipment may be further sub-divided into several entities, e.g. the one which performs the radio transmission and related functions, Mobile Termination, MT, and the one which contains the en
48、d-to-end application or (e.g. laptop connected to a mobile phone), Terminal Equipment. TE. This separation is used in the description of the functional communication in figure 3 but no reference point is defined in this specification. 5.2.2 USIM Domain The USIM contains data and procedures which una
49、mbiguously and securely identify itself. These functions are typically embedded in a stand alone smart card. This device is associated to a given user, and as such allows to identify this user regardless of the ME he uses. 5.3 Infrastructure Domain The Infrastructure domain is further split into the Access Network Domain, which is characterised by being in direct contact with the User Equipment and the Core Network Domain. This split is intended to simplify/assist the process of de-coupling access related functionality from non-access related functionality a
