The embodiment of the invention provides a communication transfer method based on identification information. The method is mainly applied to a communication system with the following characteristics: the communication system comprises a client and a server, and the client is in network communication with the upstream server through a special line. Referring to fig. 2, a system to which the method according to the embodiment of the present invention is applied includes:

The communication relay platform 102 executes the method to implement network connection of the system and forwarding of the network packet, and a specific implementation scheme of the embodiment of the method of the present invention is described in two aspects below.
First, as to step S1 in the embodiment of the present invention, the network link processing step specifically includes:
s11: receiving a network connection request sent by a client, and establishing a network link with the client;
s12: and detecting the network connection state between the client and the server, and if the network connection state is not connected, establishing a network link between the client and the server or sending a connection interruption notice to the client.
In the embodiment of the present invention, after the communication relay platform receives an external network connection request, it is first determined whether the identity of the request initiator is a client or a server? If the client is the client, the communication transfer platform judges whether the network connection is established with the server, and if the network connection is established, no operation is required; otherwise, network connection with the server is actively established, so that message transmission of the system can be carried out, or network connection with the server is not actively established, a connection interruption notice is sent to the client, and the specific implementation mode is flexibly adjusted according to needs. If the client side is the server, the communication transfer platform establishes network connection with the server, and in addition, the communication transfer platform can also establish network connection with all the online client sides. The establishment of the network connection in the embodiment of the present invention refers to establishing a network link with the client and/or the server.
Further as a preferred embodiment, the network link processing step further includes:
s13: receiving a network turn-off request and judging the identity of an initiator of the network turn-off request;
s14: if the network turn-off request initiator is a client, disconnecting a network link between the client and the network turn-off request initiator;
s15: and if the network turn-off request initiator is a server, disconnecting a network link between the server and the network turn-off request initiator, and sending a connection interruption notice to all the clients in the connection state.
Further as a preferred embodiment, after the step of disconnecting the network link with the client, the method further includes the following steps:
s141: and judging whether a network link with the client exists or not, and disconnecting the network link with the server if the network link with the client does not exist.
In the embodiment of the present invention, when the communication relay platform receives an external network shutdown request, it is first determined whether the identity of the request initiator is a client or a server? If the client is the client, the communication transfer platform disconnects the network link between the communication transfer platform and the client, and then further judges whether all the network connections between the client and the communication transfer platform are disconnected, namely whether the network link between the client and the communication transfer platform does not exist, if so, the only network connection between the communication transfer platform and the server is disconnected, so that the communication resource is saved, otherwise, no operation is performed; if the client is the server, after the communication transfer platform breaks the network link between the communication transfer platform and the server, sending a connection interruption notice to all the clients in the connection state, and then breaking the network links between all the communication transfer platforms and the clients.
The step of transmitting the message by the communication relay method based on the identification information in the embodiment of the present invention, in addition to the above-mentioned steps S2-S5, further includes the following steps:
s6: receiving a network message and a network message forwarding request sent by a server, wherein the network message carries identification information corresponding to a client source address;
s7: unpacking the network message to obtain the identification information carried in the network message;
s8: and sending the network message to a client through a corresponding network link according to the identification information carried in the network message.
In the embodiment of the present invention, when the communication relay platform receives an external network packet and a network packet forwarding request, it is first determined whether the identity of a requester initiating the network packet forwarding is a client or a server? If the network message comes from the client, the communication transfer platform carries out unpacking operation to obtain the identification information in the network message, establishes the corresponding relation between the identification information in the network message and the IP source address of the client, and then carries out the private line transmission of the information on the network message through the unique network connection between the communication transfer platform and the server. And if the network message comes from the server, the communication transfer platform carries out unpacking operation to obtain the identification information in the network message, and determines the network message to be transferred through a network link between the communication transfer platform and which client according to the corresponding relation between the identification information established before and the IP source address of the client. It should be noted that, in a primary information transmission process, the communication relay platform receives a request network message of a client and a response network message finally forwarded back to the server, and carried identification information is unified, that is, when the client sends the request network message, a corresponding relationship between the request network message, the identification information and a client source address is established; the server processes the request network message and sends out a corresponding response network message, and the communication transfer platform returns the response network message to the client according to the corresponding relation between the identification information and the client source address established before.
