The procedures in the following subclauses describe the process for sharing group configuration from an MC system to an IWF where the IWF needs to make use of the MC service group and from an IWF to an MC system where the MC system's clients need to make use of the group. The procedures in this subclause are based upon subclause 10.2.7 in TS 23.280.
Figure 10.2.3.2-1 below illustrates the case where the MC system provides the group configuration to the IWF, e.g. due to an action by an administrator or because the primary MC system of some of the MC service group members is the IWF.
Pre-conditions:
The MC service group is defined in the MC system.
One or more LMR users are members of the group.
The MC system of the MC service group has been configured with addressing information for the group management function in the IWF.
The MC system of the MC service group is authorized to provide group configuration information to the IWF.
The group management server in the MC system of the MC service group provides the configuration information related to the MC service group to the IWF.
The IWF responds to the group management server of the MC system of the MC service group that the configuration has been received and stored correctly.
Figure 10.2.3.3-1 below illustrates the case where the IWF requests the group configuration from the MC system, for example because a user on the IWF is a member of the group.
Pre-conditions:
The MC service group is defined in the MC system.
One or more LMR users are members of the group.
The IWF does not have the configuration for the MC service group stored.
Figure 10.2.3.4-1 below illustrates the case where the IWF provides the group configuration to the MC system, e.g. due to an action by an administrator or because some of the IWF's MC service group members are homed on the MC system.
Pre-conditions:
The group is defined in the IWF.
One or more MC service users are members of the group.
Figure 10.2.3.5-1 below illustrates the case where the MC system requests the group configuration from the IWF, for example because an MC service user receiving service in the MC system has the group configured in the user profile.
Pre-conditions:
The MC service group is defined in the IWF.
One or more MC service users are members of the group.
The group management server in the MC system does not have the configuration for the MC service group stored.
The MC system has been configured with addressing information for the group management function in the IWF.
The procedure for subscription from IWF for group configuration information to the group management server in the primary MC system of the MC service group is shown in Figure 10.2.3.6-1.
Pre-conditions:
The MC service group is defined in its MC system.
One or more group members are defined in the LMR system.
The IWF has received group information from the GMS in the primary MC system of the MC service group.
The group management server in the primary MC system of the MC service group sends an IWF group information subscribe response to IWF indicating success or failure of the request.
The procedure for notification of group configuration information from the group management server in the primary MC system of the MC service group to the IWF is shown in Figure 10.2.3.7-1.
Pre-conditions:
The IWF has subscribed to the group configuration information for the MC service group in the group management server in the primary MC system of the MC service group.
The group management server in the primary MC system of the MC service group has received and stored new group configuration information for the MC service group.
The IWF sends an IWF group information notify response to the group management server in the primary MC system of the MC service group indicating the success or failure of the notification.
The procedure for subscription by the group management server in the MC system to the IWF for group configuration information is shown in Figure 10.2.3.8-1.
Pre-conditions:
The group is defined in the LMR system.
One or more group members are defined in the MC system.
The group management server in the MC system has received group information from the IWF.
The procedure for notification of group information from the IWF to the group management server in the MC system is shown in Figure 10.2.3.9-1.
Pre-conditions:
The group management server of the MC system has subscribed to the group configuration information for the group in the IWF.
The group management server in the MC system sends an IWF notify group information notify response to the IWF indicating the success or failure of the notification.
