Abstract: Methods for handling Media-based Modulation (MBM) in a wireless network (1000) by a Mission Critical (MC) Gateway (GW) User Equipment (UE) (300) are provided. The method includes storing information associated with an identifier at the MC gateway UE (300) in response to receiving an MC gateway Multimedia Broadcast Multicast Services (MBMS) bearer announcement from an MC client (100). The MC gateway UE (300) uses the identifier and the information to activate for monitoring the MBMS bearer by the MC gateway UE (300). Further, the method includes sending an MBMS listening status report to the MC client (100) based on the MC GW MBMS bearer announcement. Further, the method includes establishing a communication channel with the MC client (100) based on a parameter to receive an MC service data from the MC gateway UE (300), where the MC gateway UE (300) forwards the MC service data to the MC client (100).

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.
