Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telec
12、ommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). The present document is a collection of NGN terminology for reference by other TISPAN-NGN documents. Introduction There is a great diversity in the terminology used for NGNs, when different bodies, differen
13、t groups within the same body and even different documents within the same group often follow their own particular usage. The same term may be used with slightly or even completely different meanings, and different terms may apply to the same object. Also, terminology with a telecommunications histo
14、ry often has to be adapted to make it suitable to NGN. Thus, it is important to find a commonly accepted set of fundamental terms within TISPAN before divergence sets in. Wherever possible, the present document refers to existing terminology from ETSI and ITU-T sources. However, because the assumpti
15、ons underlying many of those definitions have changed drasticly, a number of modifications were necessary. In some cases, new definitions of existing terms had to be introduced. Although this may lead to confusion, it follows the real situation where many terms have taken on a new meaning. ETSI ETSI
16、 TR 180 000 V1.1.1 (2006-02) 5 1 Scope The present document provides a common pool of terminology for use within the TISPAN-NGN project. It is intended that all NGN documents refer to the present document within their definitions clause for their basic terminology. If a specific term also used by th
17、e 3GPP is not defined in the present document, then the definition in the 3GPP terminology document 1 shall be valid. The present document contains both definitions and explanations of terms. Explanatory text is intended as purely informational material. The definitions are marked as such and follow
18、 the structure: 1) Term to be defined. 2) Definition text. 3) Source of definition (optional). 4) Note(s) (explanatory notes). 5) Editors notes. 2 References For the purposes of this Technical Report (TR) the following references apply: 1 ETSI TR 121 905: “Digital cellular telecommunications system

28、xt Generation Network, NGN: A Next Generation Network is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transpor
29、t-related technologies. It offers unrestricted access by users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users. The NGN is characterized by the following fundamental aspects: Packet-based transfer. Separation
30、of control functions among bearer capabilities, call/session, and application/service. Decoupling of service provision from network, and provision of open interfaces. Support for a wide range of services, applications and mechanisms based on service building blocks (including real time/ streaming/ n
31、on-real time and multi-media services). Broadband capabilities with end-to-end QoS and transparency. Interworking with legacy networks via open interfaces. Mobility. Unrestricted access by users to different service providers. ETSI ETSI TR 180 000 V1.1.1 (2006-02) 7 A variety of identification schem
32、es which can be resolved to IP addresses for the purposes of routing in IP networks. Unified service characteristics for the same service as perceived by the user. Converged services between Fixed/Mobile. Independence of service-related functions from underlying transport technologies. Compliant wit
33、h all Regulatory requirements, for example concerning emergency communications and security/privacy, lawful interception etc. Support of multiple last mile technologies.

34、 which an NGN operates. 5.1 Domains Domains describe the infrastructure owned by single operators. (General) domain: A collection of physical or functional entities which are owned and operated by a player and can include entities from more than one role. The extent of a domain is defined by a usefu
35、l context and one player can have more than one domain. Source: Based on ITU-T Recommendation Y.110 3. NOTE: Usage of the term domain in association with URIs follows the IETF related definition and usage of the term domain in association with CS and PS follows the 3GPP related definition. Administr
36、ative domain: A collection of physical or functional entities under the control of a single administration. Source: TR 101 878 4 and TS 102 261 6; very similar to definition in ITU-T Recommendation X.115 5. User domain: A collection of physical or functional entities under the control of an end-user
37、 that share a consistent set of policies and common technologies. Source: TR 101 878 4 and TS 102 261 6. Service domain: A collection of physical or functional entities offering IP based services under the control of an NGN Service Provider which share a consistent set of policies and common technol
38、ogies. Source: Based on TR 101 878 4 and TS 102 261 6. 5.2 Networks The terms listed here describe the connectivity infrastructure surrounding an NGN. Core network: A portion of the delivery system composed of networks, systems equipment and infrastructures, connecting the service providers to the a
39、ccess network. The core network is independent of the connection technology of the terminal (e.g. radio, WLAN, xDSL, ) Source: ES 282 001 7. ETSI ETSI TR 180 000 V1.1.1 (2006-02) 8 Core Transport Network: A collection of entities that provides IP transport connectivity between an Access Network and
40、another Core Transport Network, between an Access Network and another Access Network, and connectivity to Service Layer entities. Core Transport Networks are distinguished from one another based on the underlying technology, ownership and/or administrative partitioning. Core Transport Networks do no
41、t directly connect to User Domains. Source: Based on ITU-T NGN Focus Group. Access network: The collection of network entities and interfaces that provides the underlying IP transport connectivity between the device and the NGN entities. Source: ES 282 001 7. Service-oriented Interconnection (SoIx):
42、 The physical and logical linking of NGN domains that allows carriers and service providers to offer services over NGN (i.e. IMS and PES) platforms with control, signalling (i.e. session-based), which provides defined levels of interoperability. Source: TISPAN WG1. NOTE: For instance, this is the ca
43、se of “carrier grade“ voice end/or multimedia services over IP interconnection. “Defined levels of interoperability“ are dependent upon the service or the QoS or the Security, etc. Connectivity-oriented Interconnection (CoIx): The physical and logical linking of carriers and service providers based
44、on simple IP connectivity irrespective of the levels of interoperability. Source: TISPAN WG1. NOTE: For example, an IP interconnection of this type is not aware of the specific end-to-end service and, as a consequence, service-specific network performance, QoS and security requirements are not neces
45、sarily assured. This definition does not exclude that some services may provide a defined level of interoperability. However only SoIx fully satisfies NGN interoperability requirements. 6 NGN Structure 6.1 NGN components PSTN/ISDN Emulation: Provides PSTN/ISDN service capabilities and interfaces usi
46、ng adaptation to an IP infrastructure. Source: TISPAN WG 2. PSTN/ISDN Simulation: Provides PSTN/ISDN-like service capabilities using session control over IP interfaces and infrastructure. Source: TISPAN WG 2. NOTE 1: Not all service capabilities and interfaces have to be present to provide an emulat
47、ion. NOTE 2: Those are definitions of the terms or concepts “simulation“ and “emulation“, not a definition of the architectural entities used to realize them. The architectural entity “emulation subsystem“ is a consequence of the requirements posed on it, and it is called “emulation subsystem“ becau
48、se those requirements fit the above definition. NOTE 3: This definition allows for the possibility of simulation providing a complete mapping of the PSTN / ISDN service set (complete simulation).
