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.
The WTSC EEWS group was created to develop the architecture and requirements for an Earthquake Early Warning System (EEWS). This group is comprised of members of the WTSC Systems and Networks (SN) subcommittee as well as EEWS stakeholders from the California Office of Emergency Services (CalOES), USGS, Caltech, UC Berkeley, DHS, FEMA, the University of Washington, and others.
WTSC defined the original requirements, architecture, mobile device behavior, and more, for Wireless Emergency Alerts (WEA). In anticipation of the FCC Report & Order adopted on September 29, 2016, WTSC initiated various projects to develop enhancements to the existing WEA standards and solutions. This work will update the standards to increase the maximum length of WEA messages from 90 to 360 characters, support inclusion of embedded phone numbers and URLs in WEA alerts, and support the transmission of Spanish-language alerts, among many other changes. This group is comprised of members of the WTSC Systems and Networks (SN) subcommittee as well as key stakeholders from DHS, FEMA, and the National Weather Service.
Mission: The Systems and Networks Subcommittee develops, maintains, amends and enhances American National Standards and ATIS deliverables related to system aspects, networks, and terminals within the GSM family (GSM/EGPRS/UMTS) such as circuit-switched, packet-switched and IP Multimedia services including future developments. This work may be done within the Subcommittee or may be done in close cooperation with other regional and international standards and specification groups to ensure that the non-radio aspects for mobile technology meets North American regulatory and commercial requirements.
Scope: The Subcommittee provides the following functions and capabilities:
Peter Musgrove, AT&T
Greg Schumacher, Sprint
Mission: WTSC LI develops, maintains, amends, and enhances American National Standards and other WTSC deliverables related to lawful intercept within the GSM family (GSM/EGPRS/UMTS). This work may be done within WTSC LI or may be done in close cooperation with other U.S., regional, and international standards and specifications groups to ensure that respective standards and specifications for the GSM family meet North American regulatory and commercial requirements.
Scope: WTSC LI provides the following functions and capabilities:
Peter Musgove, AT&T
Greg Schumacher, Sprint
Mission: WTSC RAN: Radio Access Networks Subcommittee will develop, maintain, amend and enhance ATIS standards related to radio access network technology aspects including those of GERAN/UTRAN with their future developments as well as other broadband radio access networks. This work may be done within WTSC RAN or may be done in close cooperation with other regional and international standards and specification groups to ensure that those radio access technologies meet North American commercial and regulatory requirements.
Scope: WTSC RAN will provide the following functions and capabilities:
Farrokh Khatibi, Qualcomm
Ed Ehrlich, InterDigital
The ELOC TF is composed of members of WTSC and ESIF. It was established to focus on the North American specific aspects for improving emergency location capabilities and services such as location accuracy and operating environments. The ELOC TF is also developing the standards and requirements needed to implement the Nationwide Emergency Address Database (NEAD). ATIS serves as the official Program Manager for the NEAD LLC to ensure the successful launch of the database, which will identify and utilize the location of Bluetooth beacons and Wi-Fi access points to help identify an emergency caller’s location.
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. This work is currently focused on creating ATIS standards for Real-Time Text (RTT) mobile device behavior and an end-to-end service description.
WTSC's SN and RAN subcommittees and TIA TR8.8 are collaborating on public safety mission critical Push to Talk (PTT) voice interoperation between LMR and LTE systems.
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).
