3GPP LTE Services and FirstNet The New Paradigm for Emergency Services John Martyn, Systems Architect
Intrado continues to pioneer network innovations that save lives and improve emergency response.
FirstNet: Why LTE?
Commercial
Public Safety • • • • •
Universal 700MHz license Interoperability of users Global supply chain Applications eco-system Revenue neutral network
Network Requirements
• • • • •
More Network Capacity Better products/services Lower OpEx Worldwide eco-system Greater sources of revenue
Primary Users Public Safety: Local, Tribal, State and Federal
Why LTE? The 9/11 effect Addresses the First Responder need for nationwide interoperable broadband radio system built on a commercial costs structure. FirstNet is expected to provide solutions for multi-agency, multi-user, disaster preparedness and response use cases. Copyright Intrado, Inc. 2013 – All rights reserved

FirstNet Factors for Success
Keys to enabling FirstNet LTE-based nationwide services • • • •
One nationwide PLMN (313-100) Secondary users are anticipated Applications for primary and secondary users Roaming and Interoperability: – FirstNet requirements reflected in international standards • 3GPP via US Department of Commerce and DHS • Collaboration efforts: National Public Safety Telecommunications Council, TETRA, Critical Communications Association, ETSI Technical Committee
– Inter PLMN Roaming of data, voice, & video • • • • •
IR.65 IMS Roaming and Interworking Guidelines IR.88 LTE Roaming Guidelines IR.92 IMS Profile for Voice and SMS – QCI=1 marking IR.67 DNS/ENUM Guidelines for Service Providers and GRX/IPX IR.94 IMS Profile for Conversational Video Service – QCI=1 & 2 marking

FirstNet Mission Critical Services Paths to Mission Critical-Based LTE Services •
Since 2007 Public Safety LTE has been promoted at 3GPP – NIST is a member of 3GPP – PSCR represents FirstNet at ATIS
•
Public Safety related services tracking at 3GPP – 3GPP Rel 11 – Public Safety Broadband High Power User Equipment for BC14 – 3GPP Rel 12 – Proximity-based Services Specification (ProSe) – 3GPP Rel 12 – Group Communication System Enablers for LTE (GCSE_LTE)
•
Enhancements for First Responders suggested for 3GPP review – Very high network availability and resilience of both physical and network layers – Interworking operation with aerial platforms, e.g. manned and unmanned aircraft
3GPP release compliant systems arrive in the commercial carrier market 1 – 2 years after their “Freeze” date. Release 12 freeze is expected 2Q 2014.

New Paradigm for Emergency Services
FirstNet LTE Interoperability and Public/Private Opportunities • Scale: 51% of worldwide LTE subscriptions are in North America *Source: Global mobile Suppliers Association 2013
o LTE devices for Local, Tribal, State and Federal agencies o LTE devices for secondary users, e.g. critical infrastructure entities •
LTE interconnectivity with commercial carriers o 3GPP supports LTE roaming onto UMTS and GSM networks o Standardized services eco-system to meet interoperability requirements
•
Influence on 3GPP standards o Aggregating LTE technical needs of FirstNet users o Fostering unique services within the LTE infrastructure and device supply chain
