1 Scope
The present document specifies interoperability tests for IMS-based IPTV system for NGN Release 2. It covers the use
of main IPTV functionality via different methods. Interoperability test descriptions have been specified following the
ETSI IPT test specification framework described in EG 202 568 [i.1] and interoperability testing methodology defined
in EG 202 237 [i.2], i.e. interoperability testing with a conformance relation. Each interoperability test description
includes an end user test sequence as well as a table for checking of high level message flows at key standardized
reference points in the TISPAN IMS-based IPTV infrastructure [1] and [2].

4 IMS-based IPTV Interoperability Test Specification
4.1 Introduction
The IMS-based IPTV interoperability test descriptions (TDs) defined in the following clauses are mainly derived from
MSF 2008.169.06 [i.3], TS 183 063 [2] and TS 182 027 [1]. More specifically, these TDs focus on SIP/SDP [5], HTTP
[7], RTSP [4], IGMP [6] related messaging procedures without RACS described in clauses 5, 6, 7, 8 and 11 of
TS 183 063 [2]. TDs where RACS is involved are described in part in TS 183 048 [8].
The use of FLUTE and DVBSTP transport protocols on Xa reference point as well as IPv6 MLD are at this point not
within the scope of the present document.
4.2 Test Prerequisites
4.2.1 IP Version and protocols
4.2.1.1 IP
The present document assumes that IP-based protocols all use IPv4.
4.2.1.2 RTSP
The present document assumes RTSP [3] messages are sent only via TCP.
4.2.1.3 SIP
The present document assumes that all SIP [4] messages are sent via UDP to ensure retransmission procedures based on
SIP only and to simplify the match procedure between the message flows and real network capture.
4.2.1.4 IGMP
The present document assumes that IPTV aware UE requests for multicast group use IGMPv3 [6].
4.2.1.5 Media transport
The present document assumes that content is transported using one of the following transport technologies: MPEG2TS
encapsulation or direct RTP transport (e.g. H264 over RTP). Further it is assumed that transport of IPTV content within
MPEG2-TS layer over RTP and UDP is performed according the procedures defined in TS 102 034 [5].

9 ETSI TS 186 020 V2.1.1 (2009-12)
4.2.2 Authentication and Security
4.2.2.1 SIP
The present document assumes that no SIP-based authentication is performed.
4.2.2.2 HTTP
Personalized service selection is out of the scope of the document. Hence, no HTTP authentication is required from the
UE toward SSF or SCF. Also no authentication proxy is needed between the UE and the SCF.
4.2.3 Supported Options
4.2.3.1 Signalling Compression
"No SigComp" is the default signalling configuration in all test descriptions. Tests may be executed with signalling
compression if the required nodes support it.
4.2.3.2 SIP Provisional Message Reliability
The present document assumes there is no use of SIP 100rel option tag.
4.2.3.3 SIP precondition option tag
The present document assumes there is no use of SIP precondition option tag.
4.2.3.4 SIP timer option tag (Session Timers)
The present document assumes there is use of SIP timer option tag which supports session timer extension. The
inclusion of this option tag in a Supported header field of a SIP request or response indicates that the UE is capable of
performing refreshes. The inclusion of this option tag in a Require header of a SIP request indicates
