Lates
2、t updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates
3、on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Special Report (SR) has been produced by Advisory Committee Operational Co-ordination Group (OCG). NOTE: The SR type of deliverable was chosen to publish the contents of the document because
4、 the information is not specifically technical and is an integration of information from many sources. The current version of the present document was published after endorsement by the ETSI Operational Co-ordination Group, which represents all technical bodies of ETSI. Introduction The application
5、of Article 17 of the Framework Directive (2002/21/EC i.1) led to the production of studies like SR 002 211 i.2 carried out by ETSI, and other European Standardization Organizations (ESOs). The development of NGN concepts and other future trends is impacting widely and deeply the future of the e-Comm
6、unications Networks and Services, introducing major influence of other sectors, like IT, Broadcasting and other consumers close products and services. European authorities started a revision of the relevant regulatory documents. It is urgent that the appropriate TBs within ESOs are aware of the regu
7、latory requirements and take them appropriately into account when developing standards for the NGN. The present document results from a number of fundamental presentations offered during the ECN - standards which are produced to achieve public interest objectives; - areas where further studies are n
8、eeded. ETSI ETSI SR 002 586 V1.1.1 (2008-08) 5 1 Scope The present document is intended for both regulators and technical groups. It looks at the NGN from the technical regulatory point of view. It assesses how the EU Regulatory Framework applies to the NGN as specified by ETSI TISPAN in collaborati
9、on with 3GPP (e.g. for IMS), TC LI and ITU-T. The present document refers to the Release 1 of NGN which does not include IPTV nor does it include content matters. Regarding VoIP, the present document only looks at Voice over NGN. Only the NGN specific regulatory requirements are considered in the se
10、ction. Outside the scope are requirements which apply to any networks (e.g. EMC). 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

43、iations apply: 3GPP Third Generation Partnership Project ACR new users needs and requirements; technology evolution; competition in the electronic communications market. The transition to NGN also offers different opportunities at different levels of the telecommunication market: For operators, NGN
44、is considered essential for strategically positioning networks to compete in the increasingly converged world of services and content where voice is no longer the sole source of revenue. At a market level, NGN is partially driven by the increased demand for ubiquitous, integrated data, voice and vid
45、eo, mobile and fixed broadband, alongside the increasing role of mobile services in the broadband domain. Operators and investors seek increased revenue and profitability, greater productivity and broader service offerings. These trends are facilitating the integration of separate and distinct mobil
46、e and fixed technologies (optimized for one service) to enable the seamless distribution of services over fixed and mobile broadband networks, i.e. transport services, and to create a unified IP-based multiservice network. In other words, NGN can be viewed as a “communication network that allows unf
47、ettered access to all communication products and services, irrespective of the service provider or network connection“. 4.1 NGN Functional Architecture The functional architecture of the ETSI TISPAN NGN Release 1 is provided in the ES 282 001 i.3. TISPAN IMS (IP Multimedia Subsystem) functional arch
48、itecture is defined in ES 282 007 i.4. ITU-T NGN frameworks and functional architecture is provided in ITU-T Recommendation Y.2001 i.5 and ITU-T Recommendation Y.2012 i.6. Both the ETSI as well as the ITU-T NGN architectures are in line with regards to the separation between transport and services d
49、efined in ITU-T Recommendation Y.2011 i.7. The separation of services from transport allows them to be offered separately and to evolve independently. The separation is represented by two distinct blocks called “strata of functionality“ by ITU-T and “layers“ by ETSI TISPAN. For the purpose of the present document the term “layers“ will be used later in the text. The transport functions reside in the transport layer and the service functions related to applications reside in the ser
