ANSI ATIS 1000679-2015 Interworking Between Session Initiation Protocal (SIP) And ISDN User Part.pdf

1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-1000679.2015 Interworking between Session Initiation Protocol (SIP) and ISDN User Part As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) brings together the top global

2、ICT companies to advance the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, network functions virtualization, big data analytics, cloud services, device solutions, emergency services, M2M, cyber security, network

3、evolution, quality of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source solutions, and interoperability testing

4、. ATIS is accredited by the American National Standards Institute (ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of and major U.S. contributor to the International T

5、elecommunication Union (ITU), as well as a member of the Inter-American Telecommunication Commission (CITEL). For more information, visit www.atis.org. AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and o

6、ther criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majorit

7、y, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has appr

8、oved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standar

9、d. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this s

For ISUP specific t

35、erminology, refer to ATIS-1000113.2005, chapter 2. For SIP and SDP specific terminology, refer to RFC 3261 and RFC 2327, respectively. Definitions for additional terminology used in this interworking Standard are as follows: 3.1 Adjacent SIP Node (ASN): A SIP node (e.g., SIP Proxy or Back-to-Back Us

36、er Agent or the SIP side of an IWU) that has established a direct trust relation (association) with Incoming or Outgoing IWU entities. The SIP Proxy and Back-to-Back User Agent are defined in accordance with RFC 3261. 3.2 Incoming Interworking Unit (I-IWU): This physical entity, which can be combine

37、d with an ISUP exchange, terminates incoming calls using SIP and originates outgoing calls using the ISUP protocol. 3.3 Incoming or Outgoing: In this Standard, indicates the direction of a call (not signaling information) with respect to a reference point. 3.4 Incoming SIP or ISUP Network: The netwo

38、rk from which the incoming calls are received; uses the SIP or ISUP protocol. Without the term “network,” simply refers to the protocol. 21This document is available from the Alliance for Telecommunications Industry Solutions (ATIS), 1200 G Street N.W., Suite 500, Washington, DC 20005 22This documen

42、-1000679.2015 5 3.5 Outgoing Interworking Unit (O-IWU): This physical entity, which can be combined with an ISUP exchange, terminates incoming calls using ISUP and originates outgoing calls using SIP. 3.6 Outgoing SIP or ISUP Network: The network, to which the outgoing calls are sent, uses SIP or IS

43、UP protocol. Without the term “network,” simply refers to the protocol. 3.7 SIP with Encapsulated ISUP (SIP-I): The use of SIP with a message body that encapsulates the ISUP information according to the requirements in this Standard. 3.8 SIP Precondition: Indicates the support of the SIP “preconditi

44、on procedure” as defined in RFC 3312. In addition, this Standard makes use of the terms header field, message, message body, method, provisional response, and User Agent, which are defined in RFC 3261, clause 6. It uses the term payload type as defined in RFC 3550, and static and dynamic payload typ

45、e as defined in that RFC. Finally, it uses the terms attribute and session as defined in RFC 2327. Within this document the following terminology is used: Pass to ISUP procedures describes an operation internal to the IWU; and Send describes the transmission of a message on the applicable external n

46、etwork interface. 4 Abbreviations Parameters; Information elements and Messages. Examples: Called Party Number parameter, Initial Address Message. 2. The definition of a parameter value is written in italics and is inserted between quotation marks. ATIS-1000679.2015 8 Example: Nature of Address valu

47、e 0000011 “national (significant) number.” 5.2 Conventions for Representation of SIP/SDP Information 1. All letters of SIP method names are capitalized. Examples: INVITE, INFO. 2. SIP header fields are identified by the unabbreviated header field name as defined in the relevant RFC, including capita

48、lization and enclosed hyphens but excluding the following colon. Examples: To, From, Call-ID. 3. Where it is necessary to refer with finer granularity to components of a SIP message, the component concerned is identified by the ABNF rule name used to designate it in the defining RFC (generally from

49、clause 25 of RFC 3261), in plain text without surrounding angle brackets. Examples: Request-URI, the userinfo portion of a sip: URI. 4. URI schemes are represented by the lower-case identifier followed by a colon and the abbreviation “URI.“ Examples: sip: URI, tel: URI. 5. SIP provisional and final responses other than 2XX are represented by the status code followed by the normal reason phrase for that status code, with initial letters capitalized. Examples: 100 Trying, 484 Address Incomplete. 6. Because of potential ambiguity within a call flow
