NPSTC Releases Report on MCPTT Talkgroup Interoperability
Tuesday, January 22, 2019 | Comments

The National Public Safety Telecommunications Council (NPSTC) released a new report on mission-critical push to talk (MCPTT) that said interoperability talkgroups should mirror the nationwide LMR interoperability channels, which use standards-based consistent naming across the U.S.

The report, titled “Mission Critical Push to Talk (MCPTT): Considerations for Interoperability Talkgroup Naming and Management” finds management of interoperable communications will continue to be handled at the local level and will require extensive collaboration. The absence of a standard in MCPTT will create numerous problems as first responders travel into other jurisdictions and attempt to interpret various MCPTT talkgroup names.

The report highlights the need for collaboration among local, regional and state entities. The Common Channel Naming Working Group authored the report, which lays out a series of nationwide considerations on how to manage MCPTT talkgroup names. The report includes recommendations and makes several observations regarding how interoperability should be coordinated and the need for a common naming scheme to identify designated interoperability talkgroups.

The report was created in conjunction with the publication of “Mission Critical Push to Talk Considerations for the Management of User ID and First Responder Identity” in December. The latest report is here.

Interesting article on naming talkgroups (TG) for mission-critical push to talk (MCPTT). One question. As this is a nationwide network to support local user groups and not RF based, will there be a method of creating a TG that when used only extends to a set geographic area, say a county or region? This would then be like VLAW31 only serving the coverage of that base station.
