Classification: CPC H | IPC H

Claim 7:
8. A packet capsulation device that encapsulates for tunneling in a wireless communication channel included in a communication channel between multiple communicating terminals comprising:
a memory storing software instructions;
a storage device which stores data capable of identifying a path of a packet following an initial packet in the wireless communication channel, which is data capable of identifying an interface in the packet capsulation device transmitting the packet from a first terminal or a second terminal to the wireless communication channel and an interface in a partner device receiving the packet from the wireless communication channel; and
one or more processors configured to execute the software instructions to:
encapsulate the initial packet in communication between the first terminal and the second terminal serving as the partner terminal by adding a header for capsulation, and for non-encapsulating on reception of an encapsulated packet;
transmit the packet following the initial packet to the wireless communication channel without encapsulating, according to the data capable of identifying the path of the packet;
replace the header of the packet according to the data capable of identifying the path of the packet when transmitting the packet following the initial packet to the wireless communication channel.
