Figure 10.15.3.4.1-1 illustrates the procedure to add a newly affiliated user to an in-progress preconfigured MC service group regroup operation.
The MC service client is a member of a MC service group that is part of an in-progress preconfigured group regroup operation.
The MC service group identity and group configuration for the preconfigured MC service group has been preconfigured in the MC service client, and the MC service client has received the relevant security related information to allow it to communicate in the MC service regroup group.
The MC service client affiliates to an MC service group that is currently part of an in-progress preconfigured group regroup. The affiliation follows the procedure in section 10.8.3.1 of this specification.
The MC service client may send the preconfigured regroup response to the MC service server to acknowledge the regrouping action. These acknowledgements are not sent in response to a multicast transmission of the preconfigured regroup request.
