INTERNATIONAL TELECOMMUNICATION UNION FOCUS GROUP ON IPTV STUDY PERIOD 2005-2008 TELECOMMUNICATION STANDARDIZATION SECTOR FG IPTV-ID-0052 Original: English WG(s): 1st FG IPTV meeting: Geneva, 10-14 July 2006 INPUT DOCUMENT Source: CATR of MII, Huawei Title: Proposal studying NGN-based IPTV 1. Introduction The IPTV services have been deployed and provided in some countries, and some international standard organizations are studying the related issues. The IPTV service is one subset of streaming service, and the streaming component is one of the components in NGN. So we propose to study NGN-based IPTV related issues in FG-IPTV. 2. Discussion IPTV service is based on IP transport, it can use some NGN’s common functions to provide its service, for example, such as IP address allocation, service entry point discovery, bearer resource control, authorization and authentication. The IMS core can also provide many benefits to IPTV, such as NAT function, routing function, service trigger function. So these functions entities defined now in IMS core can also be reused by the IPTV services or be enhanced for the IPTV services, except for the NGN common components. Especially the interface protocols between the function entities in the IMS core may require to be extended for IPTV services, and the complexities should be analyzed deeply. At the same time, the non-IMS based solution maybe another candidate. And what solution to be chosen is up to carriers. Both schemes are reasonable, as long as the related technical challenges can be resolved. So there are two candidate solutions for NGN to provide IPTV service 1）IMS-based IPTV solution Integrate IPTV features with the IMS core functions besides the common functions specified in NGN.

Proposal Based on the above discussions, we have the following proposals: Study the NGN-based IPTV related issues. Study the following two NGN-based IPTV candidate solutions. IMS-based IPTV solution non-IMS based IPTV solution _______________
