A system and method for concurrently performing a group communication and a one-to-one communication in a wireless Internet Protocol (IP) network are disclosed. The method includes requesting, upon receipt of a one-to-one communication request from another terminal during a voice group communication, a concurrent mode service to the server by a compound terminal, determining, upon receipt of a group communication IP packet, whether there is a concurrent mode user among group members to receive a voice data packet corresponding to the group communication IP packet by a server, converting the group communication IP packet to a text data packet in the presence of a concurrent mode user by the server, transmitting the text data packet to the concurrent mode user by the server, and transmitting the voice data packet corresponding to the group communication IP packet to group communication mode users except for the concurrent mode user by the server.
