8、ty are key aspects of interconnection between the various national and international network operators. Consequently, it is important to aim at assuring the compatibility of user terminal equipment among the respective networks, and the interoperability of the various network entities with regard to
9、 bearer aspect and service compatibility. To help achieve this objective, Recommendation ITU-T Q.3940 describes a series of tests that could be performed as part of the interconnection process before live traffic is present.

ITU-T Q.3940 (08/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunicati
11、on Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (W
12、TSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on 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
13、 within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Rec
14、ommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language s
15、uch as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recomm
16、endation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of appr
17、oval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB

21、e This Recommendation defines the tests purposes (TPs) for next generation network (NGN) IP multimedia subsystem (IMS) interconnection tests between national and international network operators, covered by ITU International Telecommunication Regulations, at the IMS interconnection (Ic) interface and
22、 NGN network-to-network interface (NNI)/SIP-I. Such tests have been developed to verify the overall compatibility of the session initiation protocol (SIP), the integrated services digital network (ISDN) and the non-ISDN (public switched telephone network (PSTN) over the national or international NGN
23、s, with regard to the use of end devices in the relevant networks (recommended by the network operator). The test specifications cover the procedures described in ITU-T Q.1912.5 for Profile C (SIP-I). The specified test purposes are the basis for bilateral tests between national or international net
24、work operators. If the test between network operators is agreed, the test purposes are performed as defined in the current Recommendation. Any modification of the requirements described in, and based on, national requirements, needs additional test purposes that are not described in the current Reco
25、mmendation. Any additional test may be defined and agreed between the test staff of the network operators. This Recommendation is technically equivalent to and compatible with b-ETSI TS 101 585. 2 References The following ITU-T Recommendations and other references contain provisions which, through r

47、association) with incoming or outgoing IWU entities. 3.2.2 basic call control (BCC): Signalling protocol associated with the DSS1 ISDN Basic Call control procedures of Recommendation ITU-T Q.931. 3.2.3 incoming or outgoing: Direction of a call (not signalling information) with respect to a reference
48、 point. 3.2.4 incoming interworking unit (I-IWU): Physical entity, (which can be combined with a BICC ISN or ISUP exchange), that terminates incoming calls using SIP and originates outgoing calls using the BICC or ISUP protocols. 3.2.5 incoming SIP or BICC/ISUP (network): Network, from which the inc
49、oming calls are received, that uses the SIP or BICC/ISUP protocol (without the term “network“, it simply refers to the protocol). 3.2.6 inopportune: Specification of a test purpose covering a signalling procedure where an inopportune message, (type of message not expected in the IUT current state), is sent to the IUT. 3.2.7 outgoing interworking unit (O-IWU): Physical entity, (which can be combined with a BICC ISN or ISUP exchange), that terminates incoming calls using BICC or ISUP protoc
