Foreword This Technical Report (TR) has been produced by ETSI
18、 Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). The present document defines the TISPAN_NGN Release 1 requirements, features and documentation set together with their inter-relationships. Introduction The present document define
19、s Release 1 of an anticipated series of releases of TISPAN NGN. The TISPAN NGN is described in terms of the requirements and content capabilities and Release 1 is defined by the documentation set and the features that these support. Clause 4 provides a general description of an NGN In order to fulfi
20、l these general objectives of an NGN, the present document focuses on key initial capabilities and a generalized architectural principle to enable an NGN to be a flexible platform allowing future enhancements and releases. The TISPAN NGN is specified using a release mechanism. The present document p
21、rovides an overview of the requirements for the first release. No assumptions should be made about future releases. Throughout the present document, references to NGN are assumed to be references to TISPAN NGN unless otherwise indicated. ETSI ETSI TR 180 001 V1.1.1 (2006-03) 6 1 Scope The present do
22、cument provides a description of the content of NGN Release 1 and defines the release through a catalogue of the Release 1 documentation set. The inter-relationships between release 1 documents and the features supported is also provided The present document is structured as follows: - clause 4 prov
23、ides an overview of Next Generation Networks (NGN); - clause 5 describes the NGN Release 1, the Requirements to support Release 1 and outlines the major capabilities that Release 1 will fulfil; - clause 6 defines the content and capabilities of NGN Release 1; - clause 7 introduces the Release 1 plan
24、 documentation set. The present document does not provide solutions for the technical issues that are identified therein. 2 References For the purposes of this Technical Report the following references apply: 1 TR 180 000: “Telecommunications and Internet converged Services and Protocols for Advance

28、nt, the terms and definitions given in TR 180 000 and the following apply: access network: collection of network entities and interfaces that provides the underlying IP transport connectivity between the device and the NGN entities NOTE: An example of an “Access Network“ is ADSL. hand-over: special
29、case of session continuity where the incurred interruption or loss of data is below certain limits such that real-time services can be continued despite of the change of access point ETSI ETSI TR 180 001 V1.1.1 (2006-03) 7 mobility management: set of functions used in the Core Network to provide mob
30、ility NOTE: These functions include authentication, authorization, location updating, paging, download of user information and more. nomadism: ability of the user to change his network access point on moving; when changing the network access point, the users service session is completely stopped and
31、 then started again NOTE: I.e. there is no session continuity or hand-over possible. It is assumed that normal usage pattern is that users shutdown their service session before moving to another access point. personal mobility: mobility for those scenarios where the user changes the terminal used fo
32、r network access at different locations NOTE: The ability of a user to access telecommunication services at any terminal on the basis of a personal identifier, and the capability of the network to provide those services delineated in the users service profile. roaming: ability of the users to access
33、 services according their user profile while moving outside of their subscribed home network NOTE: I.e. by using an access point of a visited network. This requires the ability of the user to get access in the visited network, the existence of an interface between home network and visited network, a
34、s well as a roaming agreement between the respective network operators. seamless hand-over: hand-over is further called seamless when the terminal location change does not result in delay or loss of data that would be perceived by the user as degradation of quality of service seamless mobility: abil
35、ity to provide services irrespective of changes that may occur by user/terminals activities NOTE: The user is able to change his network access point, as he moves, without interrupting his current service session, i.e. handovers are possible. In some situations, the hand-over may lead to a briefly s
36、uspended service session or it may require a change in the level of service provided as a consequence of the capabilities of the new access point to which the user has become connected through the hand-over process. seamless service (or seamless service continuity): Same as service mobility. service
37、 mobility: mobility, applied for a specific Service NOTE: I.e. the ability of a user to use the particular (subscribed) service irrespective of the location of the user and the terminal that is used for that purpose. session continuity: ability of a user or terminal to change the network access poin
38、t while maintaining the ongoing session NOTE: This may include a session break and resume, or a certain degree of service interruption or loss of data while changing to the new access point. terminal mobility: ability for a terminal to be moved to different physical locations NOTE: When being moved
39、it may or may not connect to an access network that is the same in terms of technology to that of the access network that it has just moved from. terminal mobility: mobility for those scenarios where the same terminal equipment is moving or is used at different locations NOTE: The ability of a termi
40、nal to access telecommunication services from different locations and while in motion, and the capability of the network to identify and locate that terminal. user mobility: ability for a subscriber to move to different physical locations and be able to use one or more devices connected to one or mo
