ITU-T Q.3402 (02/2008) i Recommendation ITU-T Q.3402 NGN UNI signalling profile (Protocol set 1) Summary Recommendation ITU-T Q.3402 defines the NGN user-to-network interface (UNI) signalling profile for use between users and networks of protocol set 1 fo

8、r voice, video and data services. Source Recommendation ITU-T Q.3402 was approved on 29 February 2008 by ITU-T Study Group 11 (2005-2008) under Recommendation ITU-T A.8 procedure. Keywords NGN, profile, SDP, signalling, SIP. ii Rec. ITU-T Q.3402 (02/2008) FOREWORD The International Telecommunication

9、 Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questio

10、ns and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations o

11、n these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the

12、 expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or appli

13、cability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with t

14、he Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicab

15、ility of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implemen

16、t this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

ITU-T Q.3402 (02/2008) 1 Recommendation ITU-T Q.3402 NGN UNI signalling profile (Protocol set 1) 1 Scope This Recommendation specifies a service-level profile,

21、 i.e., SIP/SDP interface description between a user and a network, and a transport-level profile, e.g., RTP. For protocol set 1 of the NGN UNI profile, this Recommendation covers multimedia (voice, video, and data) which include VoIP, multimedia telephony, DTMF, T.38 fax, and multimedia ring back an

22、d ringing tones and announcements. This Recommendation covers all terminal types, e.g., SIP residential gateway, SIP phone, and SIP IP PBX. Therefore, the following UNI interfaces are specified: SIP residential gateway-to-service provider, where PSTN/ISDN terminals or IP phones can be connected to r

23、esidential gateway. SIP phone-to-service provider, where the SIP phone can be either a soft phone or a hard phone implemented by IMS-based SIP specifications. SIP IP PBX-to-service provider, where the IP PBX can be either a proxy or B2BUA. 2 References The following ITU-T Recommendations and other r

24、eferences contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to
