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?

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.

Network Requirements

Public Safety

• Universal 700MHz license • Interoperability of users • Global supply chain • Applications eco-system • Revenue neutral network

Commercial

• More Network Capacity • Better products/services • Lower OpEx • Worldwide eco-system • Greater sources of revenue

FirstNet Factors for Success

• 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


Keys to enabling FirstNet LTE-based nationwide services

3GPP services via IMS Architecture


• Fully interoperable IMS Core and local breakout connection

FirstNet Mission Critical 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.


Paths to Mission Critical-Based LTE Services

3GPP Roaming Voice and Messaging


• VoLTE, RCS and Interoperability are now part of PSCR testing initiatives

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
