PSCR Broadband Stakeholder Meeting to Tackle MCPTT, Evolving Public-Safety Technology
Tuesday, July 02, 2019 | Comments
Mission-critical push to talk (MCPTT) will be a hot topic at the 2019 Public Safety Broadband Stakeholder Meeting, scheduled July 9 – 11 in Chicago.

One presentation in particular will discuss bridging non-Project 25 (P25) Inter RF Subsystem Interface (ISSI) LMR and Long Term Evolution (LTE) MCPTT.

Public Safety Communications Research (PSCR), the federal agency charged and funded to oversee research and development (R&D) for public-safety communications and the organizer of the July meeting, is engaged in a multiyear effort in LMR-to-LTE interworking.

PSCR recognizes the industry is focused on the P25 ISSI-based LMR-to-LTE interworking function (IWF) standards work, which is a critical solution, but does not cover the bulk of existing LMR systems. The Alliance for Telecommunications Industry Solutions (ATIS) is overseeing this work.

PSCR is performing research in the non-ISSI space with a primary focus on analog FM and P25 systems that aren’t ISSI capable. The research focus is on creating architecture/prototype capabilities that are open source and Third Generation Partnership Project (3GPP) compliant with the MCPTT Application Server via Interworking Function. The software-defined radio (SDR) solution must be relatively inexpensive without proprietary technology and without donor radios used in gateway/bridging system interfaces.

The goal is LMR-to-LTE capabilities that connect to 3GPP broadband public-safety networks by having a software-defined radio (SDR) “talk to the LMR tower like it is a radio” that public-safety agencies can afford to use in their coverage areas.

PSCR staff will participate in 3GPP standards to add to IWF if needed and are ensuring the efforts complement work in the gateway radio over IP (RoIP) area funded by the Department of Homeland Security (DHS).

Another presentation will discuss end-to-end MCPTT and the cooperative agreement with Sonim Technologies, the main awardee, and Nemergent Solutions, the sub-awardee. The project aims to deliver an end-to-end platform that advances mission-critical voice.

This project includes the integration of mission-critical services onto user equipment (UE) as well as the implementation of the various mission-critical services servers. The deliverables include MCPTT integration and the creation of various software development kits (SDKs) for standard mission-critical services

The agreement also covers implementing an MCPTT experience on the end-to-end system, MCPTT server components, and testing interoperability of the components and with first responders in the field.

MCPTT is just one of the many topics on the agenda of the meeting. Other sessions will discuss expanding subscriber identity module (SIM) card use for public safety, data sharing and differential privacy, numerous video topics, internet of things (IoT) and wearables. The full agenda is here.

I can not see what is going to be different in the future. For decades now a first responder carried his radio and his or her cellphone. Now they will carry two cellphones because the first responder cellphone is going to have restrictions for use, and they will again carry two devices. So what changed? They can just as well have a radio and a cellphone and still do the job the same. Why try to connect the two together? It does not make sense.
