Mission Critical Push To Talk (MCPTT) over LTE

3GPP‑Page   ToC    
V13.1.0 (Wzip)  2016/06  88 p.

Rapporteur:  Mr. Haigh, Peter
See also:  MCPTT-related TS/TR

The present document contains a study of the security aspects of the Mission-Critical Push-To-Talk (MCPTT) service and its interaction with the network. This includes an analysis of the threats to the service, the security requirements to mitigate those threats and an evaluation of possible technical solutions designed to meet the security requirements of the service.

This study will include consideration of relevant 3GPP specifications, particularly for ProSe and GCSE.

The focus of the present document is to support public-safety use of MCPTT as prioritised by SA#66 (SP-140870). Some features may not be applicable to MCPTT for commercial purposes (e.g. Ambient Listening).
