Description and Objectives (1)
•
Work Area:
•
This Work Item is the first in a series of Work Items intended to deliver a complete set of Push-to-Communicate for Public
Safety (PC_PS) application and service layer standards (for voice and data). Hence “PC_PS ”. As such, this work item will
have a very limited scope, serving as a limited OMA PoC Enabler Update from current version of PoC v2.1 with no specific
Public Safety requirements because specific Public Safety requirements will be covered by future WIDs.
Issues this Work Item aims to solve:
•
•
•
•
•
PC_PS v1 – Update PoC v2.1 to support 3GPP Release 12 LTE and relevant key features based upon completed 3GPP requirements up through
Release 12, in preparation of future upgrades from PC_PS v1 to be aligned with 3GPP Public Safety Requirements in subsequent 3GPP
Releases.
This update (PC_PS v1) will be synchronized to 3GPP Release 12, but excluding:
• Group Communication System Enablers for LTE (GCSE_LTE)
• Proximity Services (ProSe)
This update (PC_PS v1) will be synchronized to 3GPP Release 12, and shall include:
• Update PoC v2.1 SIP/IP Core operations to align with 3GPP Release 12 LTE architecture
• Adapt PoC v2.1 Multicast (currently using MBMS over UTRA) to use eMBMS over LTE
Objectives
•
OMA will develop application and service layer standards in a synchronized manner with 3GPP. This Work Item is the first in a series of Work
Items for PC_PS. This work item is in preparation of future PC_PS Work Items which take use cases based on harmonized global Public Safety
requirements.
•
Note: OMA does not intend to generate Public Safety (PS) broadband requirements for PC_PS. Rather it is expected that 3GPP will collect and
consolidate such inputs from government authorities (e.g., FirstNet and UK Home Office who have indicated a preference to coordinate via 3GPP
for a set of globally harmonized requirements).
•
OMA intends to create PC_PS application and service layer technical specifications driven by Public Safety requirements developed by 3GPP
• Example: It is anticipated that 3GPP Release 13 will define requirements for “Mission Critical Push-to-Talk over LTE” through direct
member participation in 3GPP while drawing inputs from other relevant SDO/FORA (e.g., FirstNet, UK Home Office, US NPSTC, TCCA,
APCO, ETSI EMTEL and other Public Safety related organizations around the world).

Slide #5
[OMA-Template-WIDpresentation-20130101-I]
Description and Objectives (2)
•
Market benefits:
•
Mobile Network Operators will be able to provide Push-To-Communicate voice and data application services for both
Mission Critical Public Safety (or Public Protection and Disaster Relief PPDR) and Critical Communications Enterprise
markets that operate across multiple 3G, 3.5G, 4G, WiFi, Satellite, etc. Technologies.
Additionally, as PoCv2.1 predates LTE, update of this OMA Enabler is timely for the wireless industry.
•
Time to market:
•
PC_PS v1 – Align PoC v2.1 to 3GPP Release 12 using current PoC v2.1 PTT, etc. services (e.g., PC_PS v1)
•
•
•
Global market deployments of PoC for Public Safety are expected to follow globally coordinated Public Safety
broadband definition and deployment efforts (currently led by U.K and U.S. government authorities via 3GPP)
Complexity:
•
•
* PC_PS v 2, 3, 4, ... – Enhance PC_PS v1 to fully support Public Safety in 3GPP Releases 13, 14, 15
* Separate WIDs for each of these subsequent PC_PS releases is outside the scope of this WID
Expected market acceptance:
•
•
October 2014
PC_PS v 1, 2, 3, 4, ...: Level of complexity1 will vary with each release; however previous efforts invested in OMA PoC
Enabler v1.0, v2.0 and v2.1 afford considerable body of design knowledge in PTT over Cellular (PoC) networks that
was contributed by a majority of industry experts in this field (from 2003 – 2011) from which PC_PS can draw
Uniqueness:
•
No global Push-To-Communicate for Public Safety application standards exist that are built upon all-IP and SIP
infrastructures which can be instantiated and operate across multiple 3G, 3.5G, 4G, WiFi, Satellite, etc. wireless
technologies
Note 1: POC V2.1 comprises of 10 Specs and 19 Supp Docs

Description and Objectives – Informative
• This page is informative only. It describes the Objectives and Deliverables of future
PC_PS releases. Each PC_PS release will be kicked off with a separate WID.
•
Considerations for Future Deliverables
•
•
•
Deliverables for Public Safety will be done over multiple PC_PS releases to synchronize with
other SDOs in order to optimize the use of collective resources and avoid fragmentation and
duplicate efforts.
OMA will work with other SDOs, as required, to achieve OMA PC_PS interoperability with legacy
PS narrowband radio systems to support the 3GPP defined global PS requirements.
Issues for future PC_PS Work Items:
•
•
PC_PS v2 shall be aligned with 3GPP Releases 12 and 13 with respect to Public Safety Support;
e.g.,:
•
Support Public Safety enhancements, features, applications, services, etc. as agreed in 3GPP Releases 12
and 13 use cases & requirements
•
Update PC_PS to align with other Public Safety relevant OMA enablers (e.g., Presence, XDM, CPM and
Network APIs) to address the evolved PoC service environment while applying lessons learned from
commercial deployments of OMA PoC
PC_PS v 3, 4, 5,... shall be aligned with 3GPP Release14, etc. ... with respect to
Public Safety support; e.g., :
•
Support Public Safety enhancements, features, applications, services, etc. as agreed in 3GPP Release 14,
15, ... use cases & requirements

Main Use Cases - Informative
(2 – Future global Public Safety broadband)
3GPP Perspective [http://www.3gpp.org/Public-Safety, July 2013]:
• Public safety users (i.e., first responders, fire fighters, law enforcement, terror incident & natural disaster response, emergency
medical care, airport operations, etc.) are an important community both economically and socially but the market for systems based
on public safety standards is much smaller than for commercial cellular. Specialised public safety and critical communications
technology cannot attract the level of investment and global R&D that goes in to commercial cellular networks. Establishing
common technical standards for commercial cellular and public safety offers advantages to both communities:
• the public safety community gets access to the economic and technical advantages generated by the scale of commercial cellular networks, and
• the commercial cellular community gets the opportunity to address parts of the public safety market as well as gaining enhancements to their
systems that have interesting applications to consumers and businesses .
A strong standards-based approach will ensure interoperability between vendors leading to a competitive equipment market.
• The U.S. National Public Safety Telecommunications Council (NPSTC) and other organizations recognized the desirability of
having an interoperable national standard for a next generation public safety network with broadband capabilities. With NPSTC,
TCCA, ETSI Technical Committee TETRA and other organizations backing LTE there is now a clear global consensus that LTE will
be the baseline technology for next generation broadband public safety networks.
U.S. First Responder Network Authority (FirstNet) Perspective [http://www.ntia.doc.gov/page/about-firstnet]:
• Using a nationwide spectrum license, FirstNet will provide a single platform for daily public safety communications. When natural
disasters, threats to national security, or other emergencies occur anywhere in the country, FirstNet will enable local, state, regional
and national emergency responders to communicate at the direction of the incident commander.
• FirstNet will be built to public-safety grade standards using Long-Term Evolution (LTE) wireless technology, the most
advanced available today. FirstNet will deliver greater coverage, capacity, connectivity, cybersecurity and resiliency than the
current multiplicity of diverse public safety wireless systems.
• Police, firefighters and emergency medical service personnel will still rely on their land mobile radio (LMR) networks for missioncritical voice with FirstNet providing high-speed data, supplemental commercial grade voice and eventually mission-critical LTE
voice. FirstNet also will support the integration of LMR networks, even after LTE voice is provided.
