scope:

The present 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).

The present 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.

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

The parameters defined by the management objects in the present document are configured in the MCPTT UE using online 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:

- 3GPP TS 24.379 [7]

- 3GPP TS 24.380 [8]

- 3GPP TS 24.381 [9]

- 3GPP TS 24.382 [11]

- 3GPP TS 24.384 [12]

The common network operation means both on-network operation and off-network operation in the present document

The following management objects are defined in the present 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.
