24、r emerging technologies such as VoIP, as well as access, local and wireless services. This document specifically addresses the ordering process associated with dedicated direct SP SP SIP-based voice service. 1.2 Background The industry recognized the benefits and a need for a uniform ordering proces

25、s and corresponding tools to facilitate SIP-based Voice Interworking between two NGN Provider networks. The Ordering Solutions committee of OBF developed this document to begin to address that need. 1.3 Scope The development of signaling, media, security and other interoperability technical requirem

26、ents and specifications by other ATIS committees, e.g., PSTC, will drive the ordering information exchange needs and specifications to be documented and maintained by the Ordering Solutions Committee. Although mechanization of this process is outside the scope of this document, sufficient experience

27、 with the manual forms and processes described herein may lead to a stable and widely employed process warranting mechanization. Subsequent documents will address any corresponding mechanized requirements for managing and exchanging information. This document serves as the repository for the specifi

28、cation (and its development) for information exchanged manually using ordering forms identifying ordering attributes for Layer 3 and above SIP-based voice connections. This specification assumes layer 1 and 2 attributes, although included in the “Data Worksheet”, will be processed through existing O

29、BF ordering procedures, and are not impacted herein. 1.4 Purpose The purpose is for this document is to serve as the baseline industry specification for SIP-based voice interworking and to be a placeholder for ongoing analysis and decisions determined by NGN Providers and the ATIS committees respons

30、ible for further developing this uniform “industry specification,” including the process, worksheets, job aids and reference material used to facilitate the planning and implementation of NGN SIP-based voice interoperability.

40、F SELECTED ATIS TECHNICAL REPORTS 3.1 PTSC NGCI Task Force Establishing and specifying the fixed protocol and configuration profiles, and the parameters selectable by providers, so that they may be applied uniformly and consistently, will ensure a reliable standard that facilitates interoperability.

41、 The ATIS Next Generation Carrier Interconnection (NG-CI) Task Force (TF) Technical Reports (TRs) specify a standards-based interface for network-to-network interconnection for next generation network services. 3.1.1 Testing Configuration for IP Network to Network Interconnection, SIP-Based Voice Th

42、is technical report 6 specifies the “test configurations” for verifying the conformance with the desired configuration and service interoperability. The test configurations are used as a framework to specify the call flows in the Test Suites document (see section 3.1.2), which are used to verify the

43、 settings (to support ingress and egress processing) of the network border elements for interoperability of a service between providers. 3.1.2 Test Suites for IP Network to Network Interconnection, SIP-Based Voice This technical report 7 specifies a set of call “test scenarios” involving SIP and oth

44、er signaling messages to verify the accuracy of an expected reaction to an event or a sequence of events appropriate to the previously signaled message. This “expected reaction” is based upon the protocol profile established for the messages that flow across the NNI. The purpose of these tests is to

45、 confirm appropriate implementation of SIP messages across the NNI for common call scenarios. 3.1.3 Protocol Suite Profile for IP Network to Network Interconnection, SIP-Based Voice This technical report 8 provides the service specific “protocol requirements” to support service interoperability. Thi

46、s technical report identifies a set of protocols and specifies their profile so that signaling, media, and network related parameters can be uniformly and consistently utilized across the Interconnection interface. 3.1.4 Technical Parameters for IP Network-to-Network Interconnection, SIP-Based Voice

47、 This technical report 9 specifies the “Interconnection Technical Parameters” that need to be collected and eventually exchanged between two service providers so that they can successfully interconnect IP based facilities and VoIP services at an NNI. It documents the set of technical specifications

48、pertaining to the parameters and attribute settings that are selectable by the interconnecting providers, which need to be discussed and agreed upon when preparing for SIP-based voice services. Appendix 4 is the “Data Worksheet Field Reference Guide” which contains specific information for each fiel

49、d based upon ATIS PTSC Technical Parameters for IP Network to Network Interconnection 9.
