Method, system, storage medium for communication session

A method for a communication session, applied on a visiting server, wherein the method comprises:

• sending a specified amount of money from a visiting server blockchain address to a first terminal blockchain address for marking a first terminal blockchain address session state as connectable;
• receiving a session request message directly from a first terminal,
• wherein the session request message comprises a session request message identifier, and a first terminal session account;
• wherein the first terminal session account comprises:
• the first terminal blockchain address or an address mapped one-in-one to the first terminal blockchain address, a first terminal attribution server connection address, a visiting server blockchain address, and a visiting server attribution server connection address;
• wherein the first terminal attribution server connection address identifies a blockchain network corresponding to the first terminal blockchain address;
• wherein the session request message identifier is a randomly generated sequence number that identifies a session and a session signaling initiated by the first terminal to the visiting server;
• wherein the session request message further comprises:
• a session request message signature, and the session request message signature is a blockchain signature message generated based on the first terminal blockchain address and the session request message identifier;
• verifying whether the session request message signature is a blockchain signature of the first terminal blockchain address based on the first terminal blockchain address and the session request message identifier;
• in response to successful verification of the session request message signature, determining the first terminal blockchain address session state based on a transaction record between the visiting server blockchain address and the first terminal blockchain address;
• and
• sending a session response message directly to the first terminal corresponding to the session request message identifier based on the first terminal blockchain address session state and the session request message.
