The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Specifically, the disclosure related to apparatus and methods for supporting ad hoc group standalone SDS in MCData service. A method incudes receiving, by MCData server of primary MCData system, first data transfer request message from MCData client of primary MCData system for determining target MCData users for standalone SDS. Further, determines whether criteria for determining a list of MCData users or a list of MCData users associated with primary and partner MCData system is received. Further, determining list of MCData users based on criteria when criteria is received, and creates an ad hoc group, assigns pre-configured group and ad hoc group ID. Also, creating an ad hoc group based on list of MCData users associated with primary and partner MCData system when list of MCData users are received in first data transfer request message, and assigning a pre-configured group and ad hoc group ID to created ad hoc group.
