SYSTEM AND METHOD FOR CLIENT PROTOCOL SELECTION FOR SHORT DATA SERVICE

A method for managing group short data service, SDS, communication in a mission critical, MC, data communication system, by a MCData LTE, the method including:identifying a presence of allow-to-transmit-data-in-this-group;identifying a size of payload of a group standalone SDS message; andtransmitting the group standalone SDS message to a MCData LTE group using a signaling control plane or a media plane, wherein the size of the payload of the group standalone SDS message is not greater than maximum amount of data in a single request,wherein the transmitting the group standalone SDS message comprises:in case that the size of the payload is less than or equal to maximum payload size associated with a signaling over a control plane, transmitting the group standalone SDS message using the signaling control plane, andin case that the size of the payload is greater than the maximum payload size associated with the signaling over the control plane, transmitting the group standalone SDS message using the media plane.
