TS 22.179 – MCPTT Service Requirements
3GPP TS 22.179 is the 3GPP Technical Specification for MCPTT Service Requirements. It is published in 8 releases (Rel-13 to Rel-20); the latest version is 20.0.0 in Rel-20.
Specifies stage 1 requirements for Mission Critical Push To Talk service, covering public safety, commercial, and maritime applications with fast setup and priority handling.
This specification defines the service requirements for the Mission Critical Push To Talk (MCPTT) service, which provides fast setup, high availability, reliability, and priority handling for group and private communications. It covers public safety, maritime safety, and general commercial applications such as railways and utilities. The document includes definitions for key concepts like floor control, emergency calls, group regrouping, and off-network operation. It also references common requirements moved to TS 22.280 and forms the basis for non-mission critical PTT services.

Excerpt from TS 22.179
1 Scope
The present document provides the service requirements for operation of the MCPTT Service. MCPTT makes use of capabilities included in Group Communications System Enablers and Proximity Services, with additional requirements specific to the MCPTT Service. The MCPTT Service can be used for public safety applications and maritime safety applications and also for general commercial applications (e.g., utility companies, railways and maritime usage). The requirements in this specification do not apply to GSM or UMTS.
