The SEAL client (101) of an authorized UE (110) requests a group create operation to the SEAL server (120). During the group creation, the SEAL server (120) creates and stores the information of the created group. Further, the SEAL server (120) conditionally notify the VAL/MSGin5G server regarding the group creation with the information of the group members. The VAL group members of the VAL group are notified about the newly created VAL group configuration data. Further, the SEAL server (120) provides a group creation response to the SEAL client (101) of the administrator/authorized VAL user/UE.

Another scenario is of sharing group creation notification when the group members (UE) (110) does not include SEAL client (101). Pre-conditions for the scenario are as follows: The MSGin5G Server (130) interacts with the SEAL Server (120) using the procedures over SEAL-S reference point. The MSGin5G Server (130) is aware of a legacy 3GPP message client (e.g., SMS client) in legacy 3GPP UE and interacts with it via Legacy 3GPP Message Gateway. The MSGin5G Server (130) is aware of the Non-3GPP message client in Non-3GPP UE and interacts with it via Non-3GPP Message Gateway. The group creation notification includes identities belonging to different types of UEs i.e., MSGin5G UE, Legacy 3GPP UE and Non-3GPP UE.
