9、3) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions a
10、nd 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 on th
11、ese 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 publication, the expres
12、sion “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this publication is voluntary. However, the publication may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and
13、 compliance with the publication 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 the publication i

19、t 45 to ITU-T Q-series Recommendations Technical Report TRQ.2815: Requirements for interworking BICC/ISUP network with originating/destination networks based on Session Initiation Protocol and Session Description Protocol 1 Scope This Supplement provides the requirements for specifying the interwork
20、ing between Bearer Independent Call Control (BICC) peer-to-peer protocol (i.e., ITU-T Rec. Q.1902) and ISDN User Part (ISUP) protocol (i.e., ITU-T Recs Q.761-Q.764, Q.73y.x, Q.765.x, Q.769.x), with Session Initiation Protocol (SIP) as well as Session Description Protocol (SDP) at the BICC Interface
21、Serving Node (ISN). The SIP/SDP is assumed on a “Network-to-Network Interface“ (NNI) between the BICC/ISUP network and a SIP-based network, which is an originating, transit, or a terminating/destination network. The interworking should support only services or capabilities commonly applicable to bot
22、h networks. The scope of this Supplement is illustrated in Figure 1-1, with an NNI interface between the SIP/SIP-I network and the BICC/ISUP network.1TRQ.2815_F1-1NNIScopeSIP/SIP-IIWFBICC or ISUPprotocoldomainSIPprotocoldomainFigure 1-1 Interface reference model The following NNI configurations are
23、supported, with various gateway types: SIP to BICC IP or ATM; BICC IP or ATM to SIP; SIP to ISUP; ISUP to SIP; ISUP to SIP-I; SIP-I to ISUP; SIP-I to BICC; BICC to SIP-I. The IWF is supported in the following exchanges: Originating Exchange; Intermediate National Exchange; Outgoing International Exc
24、hange; Intermediate International Exchange; _ 1SIP-I includes the MIME encoding of the ISUP, not BICC. 2 Q series Supplement 45 (09/2003) Incoming International Exchange; Destination Exchange; or Standalone Unit. Interworking with access protocols at the UNI is done via a concatenation with ISUP. 2
