| 摘要 |
The present invention discloses a method for communicating between communication apparatuses and a communication unit. The method includes: sending, by a first communication apparatus, a request for establishing a Peer to Peer (P2P) connection to a second communication apparatus through a server; initiating, by the first communication apparatus or the second communication apparatus, a command for establishing a P2P connection with the other side; establishing directly a P2P channel between the first communication apparatus and second communication apparatus based on the command for establishing a P2P channel and transmitting data packets over the P2P channel. In the present invention, a P2P channel is directly established between the communication apparatuses to communicate, so data can be forwarded without a server. Thus, the load of the server may be reduced and information interaction rate of users may be improved.
