7.9 Enhanced status
23.2823GPPFunctional architecture and information flows to support Mission Critical Data (MCData)Release 18Stage 2TS
7.9.1 General
Enhanced status corresponds to information specific to the activities performed by the mission critical service users during their operation(s) e.g. available, in operation on site, going to the operation site, or just arrived.
Enhanced status for on-network is described in clause 7.9.3 and for off-network in clause 7.9.4. Off-network enhanced status is based on ProSe capabilities as described in clause 7.16.
7.9.2 Preset values for enhanced status
The enhanced status information i.e. the set of possible values corresponding to the activities of the MCData user, shall be configured by the MCData administrator. The configuration of status values is applicable on a per-group basis, and therefore shall be part of the MCData group configuration data as described in Annex A.4.
The configuration mechanism shall allow the MCData administrator to configure a minimum of 32 possible values and allow up to 65536 separate values. The set of values may be divided into a fixed set of values defined by 3GPP standards which are common across all MCData systems, and a set which may be freely configured for any purpose.
7.9.3 Enhanced status for on-network
7.9.3.1 Sharing enhanced status information
7.9.3.1.1 Procedure
The procedure for an MCData user to share the enhanced status information to the members of the selected group is illustrated in figure 7.9.3.1.1-1.
Pre-conditions:
1. MCData user(s) on MCData client 1, 2, and n are registered for receiving MCData service.
2. The MCData users 1, 2 and n are members of the same MCData group and affiliated to the MCData service.
3. The MCData group is pre-configured with the possible values for enhanced status information.
Figure 7.9.3.1.1-1: Sharing enhanced status information
1. The user at MCData client 1 selects the MCData group to share the enhanced status information. The user also selects the value of the status information to be shared from the list of pre-configured status values available for the MCData group.
2. The procedure of group standalone SDS using signalling control plane as described in subclause 7.4.2.5, is used to deliver the enhanced status information.
3. The MCData users at MCData client 2 and n are notified of the enhanced status information.
7.9.4 Enhanced status for off-network
7.9.4.1 Sharing enhanced status information
7.9.4.1.1 Procedure
The procedure for an MCData user to share the enhanced status information to the members of the selected group is illustrated in figure 7.9.4.1.1-1.
Pre-conditions:
1. Information for ProSe direct communications corresponding to the MCData group and its mapping to ProSe Layer-2 Group ID are pre-configured in MCData client 1.
2. MCData client 1, 2 and n are members of the same MCData group.
3. The MCData group is pre-configured with the possible values for enhanced status information.
Figure 7.9.4.1.1-1: Sharing enhanced status information
1. The user at MCData client 1 selects the MCData group to share the enhanced status information. The user also selects the value of the status information to be shared from the list of pre-configured status values available for the MCData group.
2. The procedure of off-network group standalone SDS using signalling control plane as described in subclause 7.4.3.4, is used to deliver the enhanced status information.
3. The MCData users at MCData client 2 and n are notified of the enhanced status information.
