Study on mission critical communication interworking between LTE and non-LTE systems
The objective of this technical report is to study and identify solutions suitable for interworking between LTE mission critical systems and non-LTE mission critical systems that satisfy the MCPTT requirements in 3GPP TS 22.179 [2] and the MCData requirements in 3GPP TS 22.282 [20] (SDS only).
The present document refers to an IWF entity as an editorial convenience. The structure and functionality of the IWF is out of scope of the present document. The definition of IWF-1 and interactions with IWF-1 by the MCPTT system and the definition of IWF-2 and interactions with IWF-2 by the MCData (SDS only) are in scope of the present document.
