Classification: CPC H | IPC H

Claim 0:
1. A packet capsulation method that performs capsulation for tunneling in a wireless communication channel included in a communication channel between multiple communicating terminals, the packet capsulation method comprising:
encapsulating by adding a first header for capsulation to a first initial packet from a first terminal to a second terminal serving as a partner terminal;
storing data capable of identifying a path of a packet following the first initial packet in the wireless communication channel, which is data capable of identifying an interface transmitting the packet in a first device that receives the packet from the first terminal and an interface receiving the packet from the first device in a second device that receives the packet from the second terminal;
encapsulating by adding a second header for capsulation to a second initial packet from the second terminal to the first terminal;
storing data capable of identifying a path of a packet following the second initial packet in the wireless communication channel;
transmitting the packet following the first initial packet and the packet following the second initial packet to the wireless communication channel without encapsulating, according to the data capable of identifying the path of the packet; and
replacing the header of the packet according to the data capable of identifying the path of the packet following the first initial packet when transmitting the packet following the first initial packet to the wireless communication channel.
