scope:

This document defines a number of Mission Critical Push To Talk (MCPTT) Management Objects (MO) that are configured for the MCPTT UE for the operation of the MCPTT Service. The management objects are compatible with OMA Device Management protocol specifications, version 1.2 and upwards, and is defined using the OMA DM Device Description Framework as described in the Enabler Release Definition OMA OMA-ERELD_DM-V1_2 [2].

Mission critical communication services are services that require preferential handling compared to normal telecommunication services, e.g. in support of police or fire brigade.

The MCPTT service can be used for public safety applications and also for general commercial applications (e.g., utility companies and railways).

This document is applicable to an MCPTT UE supporting on-line, off-line or both on-line and off-line configuration of the configuration management client.

This document is applicable to an MCPTT UE supporting off-line configuration of the group management client.

The parameters defined by the management objects in this document are configured in the MCPTT UE using on-line configuration over the CSC-4 reference point and using off-line configuration over the CSC-11 and CSC-12 reference points. Other specifications define how these parameters are used in the operation of MCPTT, and whether they are applicable to on-network operation or off-network operation, or both. The common network operation means both onnetwork operation and off-network operation in this document.

The following management objects are defined in this document:

- MCPTT UE configuration MO

- MCPTT user profile MO

- MCPTT group configuration MO

- MCPTT service configuration MO

- MCPTT UE initial configuration MO

The MOs listed above define repositories of data in the ME.
