Mission Critical (MC) systems connection to Land Mobile Radio (LMR) systems; Stage-3
The present document provides the protocol details for connecting MCPTT systems to Land Mobile Radio (LMR) systems according to the architectural procedures specified in 3GPP TS 23.283 [80].
The functional entity that provides connection of MCPTT systems to LMR systems over the external interface is the IWF. The IWF is expected to behave as a peer MCPTT system, as further detailed in clause 5 of the present document. The internal function of the IWF is out of scope of 3GPP.
NOTE: The present document will no longer be updated after its approval by plenary. All updates are being done directly to the corresponding technical specifications.
