7.19.3.1.4  Modification of ad hoc group call participants by the initiatorp. 188
Figure 7.19.3.1.4-1 below illustrates the modification of ad hoc group call participants procedure by the initiator of the ad hoc group call.
Pre-conditions:
  1. The MCVideo client 1 is the initiator of the ad hoc group call.
  2. The MCVideo users on MCVideo client 1, MCVideo client 3 to MCVideo client n are on an ongoing ad hoc group call.
  3. The MCVideo user 1 requests to remove the user of MCVideo client 3 from the ad hoc group call and add user of MCVideo client 2 into the on-going ad hoc group call.

Up
Step 1.
The MCVideo client 1 sends the modify ad hoc group call participants request to the MCVideo server in order to remove MCVideo client 3 from the ongoing ad hoc group call and add MCVideo client 2 into it.
Step 2.
The MCVideo server verifies whether the MCVideo client 1 is authorized to add or remove (modify) the participants of the on-going ad hoc group call.
Step 3.
The MCVideo server sends modify ad hoc group call participants response to the MCVideo client 1.
Step 4.
The MCVideo server sends the ad hoc group call leave request to the MCVideo client 3 in order to remove it from the on-going ad hoc group call.
Step 5.
The MCVideo client 3 notifies the user of the ad hoc group call leave request.
Step 6.
The MCVideo client 3 sends the ad hoc group call leave response to the MCVideo server.
Step 7.
The MCVideo server removes the MCVideo client 3 from the ongoing ad hoc group call.
Step 8.
The MCVideo server sends the ad hoc group call request towards MCVideo client 2.
Step 9.
The receiving MCVideo client 2 notifies the user about the incoming ad hoc group call.
Step 10.
The MCVideo client 2 accepts the ad hoc group call request and send ad hoc group call responses to the MCVideo server. The response may also contain a functional alias of the responding MCVideo user, which is verified (valid and activated for the user) by the MCVideo server.
Step 11.
The MCVideo server may notify the initiating MCVideo user of all the users who are added to the on-going ad hoc group call. This notification may be sent to the initiating MCVideo user by the MCVideo server more than once during the call when MCVideo users join or leave the ad hoc group call.
Step 12.
The MCVideo server may notify the participants about the change in the participants list of on-going ad hoc group call.

7.19.3.1.5  Modification of ad hoc group call participants by the MCVideo serverp. 190
Figure 7.19.3.1.5-1 below illustrates the modification of ad hoc group call participants procedure by the MCVideo server.
Pre-conditions:
  1. The MCVideo client 1 is the initiator of the ad hoc group call.
  2. MCVideo server determined the participants for the ad hoc group call based on the criteria specified by the MCVideo client 1 while initiating the ad hoc group call.
  3. MCVideo server continuously evaluates the criteria to monitor the list of users who meets or not meets the criteria for participating in the on-going ad hoc group call.
  4. The MCVideo server detects that the MCVideo client 5 satisfies the criteria and MCVideo client 4 stops to meet the criteria specified by the MCVideo client 1.

Up
Step 1.
The ad hoc group call is established and on-going with the participants MCVideo client 1, MCVideo client 2, MCVideo client 3 and MCVideo client 4. The participants list is determined by the MCVideo server based on the criteria specified by the MCVideo client 1 while initiating the call
Step 2.
The MCVideo server detects that the MCVideo client 5 satisfies the criteria specified by the MCVideo client.
Step 3.
The MCVideo server sends the ad hoc group call request to the MCVideo client 5.
Step 4.
The MCVideo client 5 notifies the user about the incoming ad hoc group call.
Step 5.
The MCVideo client 5 accepts the ad hoc group call request and sends the ad hoc group call response to the MCVideo server.
Step 6.
The on-going ad hoc group call is updated by adding MCVideo client 5 which satisfies the criteria specified by the MCVideo client 1.
Step 7.
The MCVideo server detects that the MCVideo client 4 is no more satisfying the criteria to be the participant of the ad hoc group call.
Step 8.
The MCVideo server sends the ad hoc group call leave request to the MCVideo client 4 and removes it from the on-going ad hoc group call.
Step 9.
The MCVideo client 4 notifies the user of the ad hoc group call leave request.
Step 10.
The MCVideo client 4 sends the ad hoc group call leave response to the MCVideo server.
Step 11.
The on-going ad hoc group call is updated by removing MCVideo client 4, which no more satisfies the criteria specified by the MCVideo client 1.

7.19.3.1.6  Modification of ad hoc group call criteria by the initiator |R19|p. 192
Figure 7.19.3.1.6-1 below illustrates the modification of ad hoc group call criteria procedure by the initiator of the ad hoc group call.
Pre-conditions:
  1. The MCVideo client 1 is the initiator of the ad hoc group call.
  2. The MCVideo users on MCVideo client 1, MCVideo client 3 to MCVideo client n are on an ongoing ad hoc group call.
  3. MCPTT user 1 requests to modify the criteria for determining the list of participants. MCPTT client 3 does not meet the modified criteria while MCPTT client 2 meets the modified criteria.

Up
Step 1.
The MCVideo client 1 sends the modify ad hoc group call criteria request to the MCVideo server which contains an updated criteria to determine the list of participants.
Step 2.
The MCVideo server verifies whether the MCVideo client 1 is authorized to modify the criteria which determines the list of participants during on-going ad hoc group video call. The MCVideo server determines the list of ad hoc group call participants based on the criteria provided and identifies that MCVideo client 3 is to be removed from and MCVideo client 2 is to be added to the group.
Step 3.
The MCVideo server sends modify ad hoc group call criteria response to the MCVideo client 1.
Step 4.
The MCVideo server sends the ad hoc group call leave request to the MCVideo client 3 in order to remove it from the on-going ad hoc group call.
Step 5.
The MCVideo client 3 notifies the user of the ad hoc group call leave request.
Step 6.
The MCVideo client 3 sends the ad hoc group call leave response to the MCVideo server.
Step 7.
The MCVideo server removes the MCVideo client 3 from the ongoing ad hoc group call.
Step 8.
The MCVideo server sends the ad hoc group call request towards MCVideo client 2.
Step 9.
The receiving MCVideo client 2 notifies the user about the incoming ad hoc group call.
Step 10.
The MCVideo client 2 accepts the ad hoc group call request and send ad hoc group call responses to the MCVideo server. The response may also contain a functional alias of the responding MCVideo user, which is verified (valid and activated for the user) by the MCVideo server.
Step 11.
The MCVideo server may notify the initiating MCVideo user of all the users who are added to the on-going ad hoc group call. This notification may be sent to the initiating MCVideo user by the MCVideo server more than once during the call when MCVideo users join or leave the ad hoc group call.
Step 12.
The MCVideo server may notify the participants about the change in the participants list of on-going ad hoc group call.
