Method and apparatus for transmitting and receiving data in mission critical data communication system

The embodiments herein provide a method for managing short data service (SDS) disposition notifications in a Mission Critical Data (MCData) communication system. The method includes identifying, by a receiving MCData User Equipment (UE), SDS disposition request type Information Element (IE) in a SDS message received from a transmitting MCData UE. Further, the method includes initiating, by the receiving MCData UE, a timer when the disposition request type Information Element (IE) is set as Delivery and Read. Furthermore, the method includes transmitting, by the receiving MCData UE, a consolidated disposition notification to the transmitting MCData UE by stopping the timer when the SDS message is read before expiry of the timer.
