Step 702: The server utilizes a session convergence algorithm, according to the type of the Bind request, and the           ESME's Internet Protocol (IP) address and port information generation Hash           Index and query from the session collection hash table for the existence of a session matching the Bind request           The set, if present, performs step 703; if it does not, step 704 is performed.                 

Step 703: directly add the session to the session set, and after returning the success response message, execute           Step 706.                 

Step 704: The server sends to the configured multiple short message service centers (SMSC, Short Message)           Service Center) creates an SMSC link and forwards the Bind login request.                 

Step 705: The server receives the success response message returned by the SMSC, and sends a success message.           To reply to the ESME, go to step 706.                 

The above steps 701 to 705 are processes for establishing a session channel.                 

Step 706: The ESME sends a submit message to the server.                 

Step 707: The server selects one in the same session set according to the load balancing algorithm.           The SMSC link forwards the submit message.                 

Here, the SMSC link is a session channel of one transport layer in the session set.                 

Step 708: The SMSC sends a submit response (submit_resp) message to the server.                 

Step 709: The server sends a submit_resp message by using a link that receives the submit message.           Go to ESME.                 

Step 710: The SMSC sends a delivery receipt message to the server.                 

Step 711: The server selects one in the same session set according to a routing algorithm.           The ESME link forwards the deliver receipt message.                 

The ESME link is also a session channel of one of the transport layers in the session set.                 

Step 712: The ESME sends a delivery response (deliver_resp) message to the server.                                     

Step 713: The server sends a deliver_resp using the link that receives the delivery receipt message.           Message to the SMSC.                 

The above steps 706 to 713 are processes for transmitting a service message.                 

Bind login request, submit message, submit_resp message, deliver in the above embodiment 7           The receipt message, the deliver_resp message, and the like are all messages specified in the short message protocol in the prior art.                 

FIG. 8 is a flowchart of implementing a peer-to-peer (P2P, Peer to Peer) short message service according to an embodiment of the present invention           The schematic diagram, as shown in Figure 8, includes the following steps:                 

Step 801: The source SMSC creates a TCP link to the server and sends a Bind login request.                 

Step 802: The server utilizes a session convergence algorithm according to the type of the Bind login request,           And the SMSC's IP address and port information generate a Hash index, and check from the session set hash table           Query whether there is a set of sessions matching the type of Bind login request, and if so, execute the step           Step 803; if not, step 804 is performed;                 

Step 803: directly add the session to the session set, and after returning the success response message, execute           Step 808;                 

Step 804: The server creates a link to the configured multiple SMSCs, and forwards the Bind login.           begging.                 

Step 805: The server receives the success response message returned by the SMSC, and sends a success message.           In response to the message to the source SMSC, step 806 is performed.                 

The above steps 801 to 805 are processes for establishing a session channel.                 

Step 806: The source SMSC sends a deliver message to the server.                 

Step 807: The server selects one item in the same session set according to the load balancing algorithm.           SMSC link, and convert the deliver message to a submit message, using the destination SMSC link           The submit message is sent to the destination SMSC.                 

Step 808: The destination SMSC sends a submit_resp message to the server.                 

Step 809: The server sends a submit_resp message by using a link that receives the deliver message.                               To the SMSC.                 

Step 810: The destination SMSC sends a deliver receipt message to the server.                 

Step 811: The server selects one in the same session set according to a routing algorithm.           The SMSC link converts the delivery receipt message into a submit message and sends it to the SMSC.                 

Step 812: The SMSC sends a submit_resp message to the server.                 

Step 813: The server sends a deliver_resp using the link that receives the delivery receipt message.           Message to the destination SMSC.                 

The above steps 806 to 813 are processes for transmitting a service message.                 

Bind login request, submit message, submit_resp message, deliver in the above embodiment 8.           The receipt message, the deliver_resp message, and the like are all messages specified in the short message protocol in the prior art.
