The present document defines a number of Mission Critical Services (MCSs) Management Objects (MO) that are configured for the UE for the operation of MCSs. 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 
MCSs are services that require preferential handling compared to normal telecommunication services, e.g. in support of police or fire brigade.
MCSs 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 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 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 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 MCSs, and whether they are applicable to on-network operation or off-network operation, or both:
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;
MCS group configuration MO;
MCPTT service configuration MO;
MCS UE initial configuration MO;
MCData UE configuration MO;
MCData user profile MO;
MCData service configuration MO;
MCVideo UE configuration MO;
MCVideo user profile MO; and
MCVideo service configuration MO.
The MOs listed above define repositories of data in the ME.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

For the purposes of the present document, the following symbols apply to all the figures:
zero or one occurrences
zero or more occurrences
one or more occurrences
If none of these characters is used the default occurrence is exactly once.
All the Management Objects (MOs) defined in the present document are compatible with OMA OMA-TS-DM_Protocol-V1_2 
All figures are informative and the design principles of OMA OMA-TS-DM_StdObj-V1_2 
are applied with the following differences:
interior nodes are represented as rectangles with solid border;
leaf nodes are represented without any border;
un-named nodes are represented by less than and a greater than characters containing a lower-case or an uppercase character, e.g. <x>, <X>;
a stadium with solid border is used for informative text i.e. to point to a Figure describing the contents of an MO; and
named nodes that share the same contents can refer to the same Figure to represent their MO contents.
A representative example is shown in Figure 3.4.1
