A method of a first terminal is provided. The method includes communicating with a first gateway by using a first internet protocol (IP) address allocated to the first terminal, according to a first IP session, in response to a distance between the first terminal and a second gateway being equal to or less than a predetermined threshold, establishing a second IP session with the second gateway while the first IP session is set in the first terminal, receiving, from a second terminal, a first IP session-release message about the first IP session via the second gateway by using a second IP address according to the second IP session, when data from the first terminal is received by the second terminal according to the first IP session, and in response to the first IP session-release message being received from the second gateway, releasing the first IP session with the first gateway.
