and determining a second terminal session account, wherein the second terminal session account comprises the second terminal blockchain address and a second terminal home server connection address; whereby the session request message causes the visiting server to forward it to the second terminal home server connection address determined based on the second terminal session account. ### Claim 6 (depends on 1) The method for the communication session according to claim 1, wherein before sending the session request message based on the first terminal blockchain address session state, the method further comprises: obtaining the first terminal blockchain address and the first terminal attribution server connection address from a blockchain identification card; and determining the first terminal session account. ### Claim 7 (depends on 1) A non-transitory computer-readable storage medium, on which a computer program is stored, wherein the computer program when executed by a processor implements the method for the communication session as claimed in claim 1. ### Claim 8 (depends on 1) The method for the communication session according to claim 1, wherein the session request message and the session response message are SIP communication protocol messages, and/or the visiting server is a SIP proxy server. ### Claim 9 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;
