The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A system and a method to handle media transmission in the Mission Critical (MC) systems or MC Video system are provided. According to the system and the method, wastage of network resources can be avoided and other participants in the group can be given chance to transmit important data as maximum number of transmissions at a time in a group call are limited by network capacity. Accordingly, efficiency of the MC Video system can be improved.
