Selected E9-1-1 Services GRs

Contact:

This proposed project will involve selected E9-1-1 Services-related GRs from the following:

• GR-3112, Emergency Services Network Interconnection
• GR-3113, Generic Requirements for a Local Location Information Server (LIS) to Support E9-1-1 Originating Location Information for IP Centrex/IP PBX
• GR-3114, E9-1-1 Network to PSAP Access Interconnection Specifications - Session Initiation Protocol (SIP)
• GR-3118, Voice over Internet Protocol (VoIP) Positioning Center (VPC) Generic Requirements
• GR-3119, Emergency Services Zone (ESZ) Routing Database (ERDB) Generic Requirements
• GR-3129, Emergency Services Gateway (ESGW) Generic Requirements
• GR-3130, Location Validation Database (VDB) Generic Requirements in Support of E9-1-1 Service
• GR-3158, Generic Requirements for a Service Provider Location Information Server (LIS)
• Two New GRs to support Next Generation E9-1-1 Network Infrastructure.

In the area of E9-1-1, Telcordia has developed and published proposed generic requirements to provide:

1. A description of specific functionality and protocol to support new E9-1-1 capabilities
2. A broad set of requirements that specify network element and network systems E9-1-1-related functions to support VoIP-based E9-1-1 emergency calls
3. Interface specifications to support interconnection to and between legacy E9-1-1 systems (including SS7, AIN, and Interexchange Carriers) or other network interconnection types (e.g., wireless, VoIP)
4. Generic Requirements to support originating and terminating access to E9-1-1 networks, including IP Centrex-originated 9-1-1 calls and IP PSAP termination from an E9-1-1 tandem using SIP.

As new technologies and architectures mature (e.g., IMS), and evolving emergency services-related functions (e.g., location determination and acquisition) and interconnection scenarios (e.g., VoIP to PSTN) are identified, the need to define new requirements and to consider modifying existing requirements is expected to continue. In addition, generic requirements should be developed and/or updated to include specifics needed to support industry consensus of the evolution of E9-1-1, including enhancements to NENA’s i2 (i2.5 items) and i3 architecture (end-to-end VoIP) scenarios.

Telcordia proposes to provide new and updated generic requirements for next generation E9-1-1 related to design, deployment, and interconnection of networks based on VoIP-originated emergency calls with consideration for emerging core network technologies such as IMS and FTTP. Modifications to existing GR documents will be initiated by: 1) industry activities that result in changes to protocols, architectures, or interconnection scenarios, 2) technical issues that may be the result of testing or deployment, or 3) input from a service/network provider, supplier, or internal Telcordia source. New generic requirements documents are planned to support the VoIP-based E9-1-1 network elements that are being proposed in NENA for enhancements to i2 and i3 architecture solutions.

Telcordia and the Funding Participants will mutually agree on which E9-1-1 GRs (a subset of the existing GRs) to analyze and update. In addition, Telcordia plans to publish new issues, as appropriate, of the aforementioned GR documents in the fourth quarter of 2008. In addition, one or more Issues List Reports (ILRs) per document may also be published throughout the year, as appropriate, to document and solicit industry feedback on proposed issue resolutions and new open issues. Interactions with participants may be via telephone calls, conference calls, faxes, and electronic mail, and may also involve group meetings.

Pursuant to provisions of the Telecommunication Act of 1996, related to the development of industry-wide generic requirements, Telcordia invites all interested parties to participate in this GR project. If your company is interested in participating in this activity, please contact Telcordia. The resulting document(s) will only be available through the purchase of an Enterprise License. Such a license is included in the participation fee for this GR project.

To proceed with this project, it is expected that Telcordia will need at least four industry participants. While the project can proceed with fewer participants, deliverables may change as a result. The participating industry members will be apprised regularly of project status and any changes in deliverables.
