Abstract: An electronic device is provided. The electronic device includes a communication circuitry, memory storing one or more computer programs, and one or more processors operatively connected to the communication circuitry and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors indivudally or collectively, cause the electronic device to establish at least one multimedia broadcast and multicast service (MBMS) subchannel with a mission critical push to talk (MCPTT) server, and, while the at least one MBMS subchannel has been established, sends a message related to switching to a unicast method, to the MCPTT server, if the reception delay time of a control message related to the MBMS subchannel received through a general purpose MBMS subchannel (GPMS) satisfies a specified first switching condition.
