WTSC NSEP ▼
WTSC NSEP is comprised of members of WTSC RAN, ESIF NGES, and PTSC. The group will develop a joint study on Emergency Services and National Security/Emergency Preparedness Next Generation Network Priority Services (NS/EP NGN-PS) coexistence on LTE Radio Access Networks (RANs). This study will focus on how Emergency Services could potentially starve NS/EP NGN-PS communications during network degradation conditions (e.g., congestion and overload conditions during disaster events) and provide guidance to help mitigate the problem.
Emergency Services & Methodologies (ESM) Subcommittee ▼
Mission: The mission of the ESIF Emergency Services & Methodologies (ESM) Subcommittee is to provide a set of minimum, practical requirements that will ensure consistent, valid, verifiable, and reproducible location data in a variety of access environments based on sound engineering and statistical practice.

Next Generation Emergency Services (NGES) Subcommittee ▼
Mission: The ESIF Next Generation Emergency Services (NGES) Subcommittee coordinates emergency services needs and issues with and among SDOs and industry forums/committees, within and outside ATIS, and develops emergency services (such as E9-1-1) standards, and other documentation related to advanced (i.e., Next Generation) emergency services architectures, functions, and interfaces for communications networks. The Subcommittee has an emphasis on standards development as it relates to North American communication networks, in coordination with the development of standards activities to include relative ATIS committees (e.g., PTSC), ITU, 3GPP, ETSI and NENA.
Activities, Role and Responsibilities
- Investigate all actual and potential SDO or SDO-like groups, in the US and globally (3GPP, ETSI, ITU, etc.) as to their connection or potential connection to standards development work that does or could affect NG9-1-1, and what their roles and actions are in the emergency communications services arena.
- Identify and establish liaison work with and from those groups with ATIS (ESIF, NGN Focus Group, PTSC, WTSC, etc.) and NENA, to handle requirements, analysis, design, and SDO standards development work coordination.
- Relay to other SDOs basic “keep in mind and act on” issues, such as the need for callback and caller location capabilities in future development of devices and new services (WiFi & WiMAX) that affect emergency communications, such as the E9-1-1 service.
- Address the needs identified in the Gap Analysis from the ATIS NGN Framework, Part III in order to:
- Formulate the NG Emergency Services standard architecture based on the IMS/NGN standards.
- Develop NENA’s i3 Stage 2/3 standard in the context of the IMS/NGN standards.
- Identify gaps and provide input to the IETF (through established liaisons such as PTSC) for Detailed Interface Design of Protocols in the context of the ATIS NGN Framework (Call Routing and Location Determination) for NG Emergency Services.
- Provide NG Emergency Services input to 3GPP Service Architecture 1/2 working groups for consideration into 3GPP Technical Report (TR) 23.837 and Technical Specification (TS) 23.167.
- Coordinate joint reviews with ETSI EMTEL on NG Emergency Services for a global standard coordination effort between NG9-1-1 (North America) and NG1-1-2 (European Union) emergency services initiatives.
- Other Activities, Role and Responsibilities may be identified as work unfolds.
Subcommittee Work Plan & Deliverables
- Serve as the coordination point within ATIS for all work in the IP domain that may have an impact on, or be impacted by E9-1-1, or emergency services in general.
- Develop NG Emergency Services Functional Architecture Specifications based on industry input such as the NENA NG9-1-1 (i3) Requirements and Functional Design, for input into the IMS/NGN standards (6-12 months).
- Develop NG Emergency Services Design Recommendations based on the above document (6-12 months).
Open to all ATIS members, and when applicable the subcommittee activities will be accessible to other organizations or groups (e.g., NENA members) that have skillsets ESIF needs to achieve the goals of the subcommittee.

Applying Common IMS to NG9-1-1 Networks▼
The ESIF Next Generation Emergency Services (NGES) subcommittee is leading a joint work effort that addresses the application of common IMS (Stage 1, 2, and 3) for the processing, transport, and/or delivery of Emergency Service calls within the NG9-1-1 network to the appropriate PSAP (ESIF Issue 81). This is a joint effort with the Packet Technologies and Systems Committee (PTSC) and the Wireless Technologies and Systems Committee Systems and Network Subcommittee (WTSC SN). Issue 81 is a continuation of work previously completed by the ESIF NGES for defining the call processing, transport, and delivery of Emergency Service calls within the NG9-1-1 network (ESIF Issue 74).
IMS Emergency Services Network ▼
Joint project led by the WTSC Systems and Networks (SN) subcommittee and coordinated with ESIF’s Next Generation Emergency Services (NGES) subcommittee and the Packet Technologies and Systems Committee (PTSC) for an IMS-based Emergency Services Network (ESN). This work includes:
- Extending ATIS-0700015 to address Multimedia Emergency Services (MMES) (WTSC Issue 44)
- Automating Location Acquisition for Emergency Services VoIP Calls (WTSC Issue 34)
