Selected E9-1-1 Services GRs

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

• GR-3112, Emergency Services Network Interconnection
• GR-3118, Voice over Internet Protocol (VoIP) Positioning Center (VPC) Generic Requirements
• GR-3157, Emergency Services Routing Proxy (ESRP) Generic Requirements
• GR-3158, Generic Requirements for a Service Provider Location Information Server (LIS)
• GR-3162, Legacy Network Gateway Generic Requirements
• GR-3165, Emergency Services Border Control Function (BCF) Generic Requirements
• GR-3166, Legacy Public Safety Answering Point (PSAP) Gateway Generic Requirements
• Two New GRs to support Next Generation E9-1-1/NG9-1-1 Network Infrastructure and/or interconnection.

In the area of E9-1-1, Telcordia has developed and published 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 Voice over Internet Protocol (VoIP)-based E9-1-1 emergency calls
3. Interface specifications to support interconnection to and between legacy E9-1-1 systems and Next Generation 9-1-1 (NG9-1-1) systems
4. Generic Requirements to support originating and terminating access to E9-1-1 networks, including IP Centrex-originated 9-1-1 calls and Internet Protocol (IP)- Public Safety Answering Point (PSAP) termination from an E9-1-1 tandem using Session Initiation Protocol (SIP).

As new technologies and architectures mature (e.g., IP Multimedia Subsystem [IMS]), and evolving emergency services-related functions (e.g., location determination and acquisition) and interconnection scenarios (e.g., VoIP to Public Switched Telephone Network [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 i3 architecture (end-to-end VoIP) scenarios, as well as transitional scenarios involving the interconnection of legacy Emergency Services Networks and PSAPs with NG9-1-1 elements and PSAPs.

The Value of Participation

Telcordia proposes to provide new and updated generic requirements for NG9 1 1 related to design, deployment, and interconnection of networks to support VoIP-originated emergency calls and IP-enabled PSAPs, with consideration for emerging core network technologies such as IMS. 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 and updated 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 2012. 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.

Telcordia Invites Your Participation

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. An Enterprise License for all document deliverables 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.
