ETSI ETSI TS 133 179 V13.3.0 (2017-01)83GPP TS 33.179 version 13.3.0 Release 131 Scope The present document speci

32、fies the security architecture, procedures and information flows needed to protect the mission critical push to talk (MCPTT) service. The architecture includes mechanisms for authentication, protection of MCPTT signalling and protection of MCPTT media. Security for both MCPTT group calls and MCPTT p

33、rivate calls operating in on-network and off-network modes of operation is specified. The functional architecture for MCPTT is defined in 3GPP TS 23.179 2, the corresponding service requirements are defined in 3GPP TS 22.179 3. The MCPTT service can be used for public safety applications and also fo

34、r general commercial applications e.g. utility companies and railways. As the security model is based on the public safety environment, some security features may not be applicable to MCPTT for commercial purposes. 2 References The following documents contain provisions which, through reference in t
