Patent ID: 8175256

Claim:
A call center system comprising a call center client, a core server, a user interface server and a protocol interaction recording module, the call center client being configured to provide various services matching with the call center system, generating a message corresponding to the service and transferring the message to the core server through the user interface server; the core server being configured to process the message transferred by the user interface server and transferring the process result to the call center client through the user interface server; and the protocol interaction recording module being connected to the call center client and the user interface server, and recording the interaction message as well as the relative information of the interaction message according to a connection identification attached in the interaction message during the protocol interaction procedure between the call center client and the user interface server, wherein the interaction message including an interface identification of the invoked application programming interface and the connection identification corresponding to the service, wherein the connection identification represents a transmitter identification and a receiver identification, and the relative information of the interaction message comprises the transmitter identification and the receiver identification of each interaction message, wherein, the call center system further comprises: a protocol interaction decomposing module for decomposing each interaction message recorded by the protocol interaction recording module according to the predefined message structure; and a protocol interaction analysis module for generating the invoke information of the application programming interface according to the decomposed information by the protocol interaction decomposing module.
