OMA to Release Initial PTT over LTE for Public Safety in Fourth Quarter


Sandra Wendelken, MissionCritical Communications, 19 May 2014 – The Open Mobile Alliance (OMA) said it is collaborating with the Third Generation Partnership Project (3GPP) to develop Long Term Evolution (LTE) standards and specifications to address public-safety service requirements. OMA’s initial effort to address the market is the Push-to-Communicate for Public Safety (PCPS) v1.0 project, and version 1.0 is expected to be released in the fourth quarter.

OMA, which supports interoperable end-to-end commercial mobile services, said PCPS will incorporate LTE as well as support multiple access technologies enabling ubiquitous coverage, and management of resources and levels of services across multiple access technologies. PCPS will be based on the OMA Push-to-talk over Cellular (PoC) Enabler.

PoC standardizes a two-way form of communications that allows users to engage in instant communications with one or more users by pushing a button on the handset. The OMA PoC standard has been prototyped, developed, and with multiple commercial deployments in the market, is a strong baseline for further enhancements to meet public-safety broadband use cases, an OMA paper said.

PCPS will incorporate the 3GPP public-safety LTE enhancements as they are defined in 3GPP. OMA also has and continues to develop other standards that may be applicable for public safety including device management, location and presence.

The OMA Device Management Enabler (OMA DM) is a framework that enables device customization and services configuration remotely, which will allow public-safety devices to be managed in an efficient and standard way. OMA has developed several location and positioning enablers focused on user plane, such as Secure User Plane Location (OMA SUPL).

The alliance is focused on extending location services into other areas considered difficult to serve, such as indoor location, as well as supporting the latest technologies such as Wi-Fi positioning, image recognition-based positioning and sensors. OMA Presence is an OMA Enabler that can interact with the OMA PoC Enabler, providing contact and presence information, contact lists and more.

The U.S. First Responder Network Authority (FirstNet) and the U.K. Home Office recently joined OMA to support this focus on public-safety standards development, the alliance said. In addition, companies including AT&T, Fujitsu, Harris, Kodiak Networks, Motorola Solutions, NextNav, T-Mobile USA and Thales Group also support OMA’s PCPS project. Many other suppliers continue to support OMA’s device management, location and presence projects.
