US Patent 7818431 Efficient exchange of service requests and responses

A client system registers (with a server system) a service request format indicating the service identifier and the parameters (along with the sequence), and the server system responds with a registration identifier and a service response format specifying the parameters that will be contained in a corresponding service response. Thereafter, to request the service, the client system merely needs to send the parameter values along with the registration identifier. The server system merely sends the parameter values according to the response format. In an embodiment, the formats are generated as extensions to Simple Object Access Protocol (SOAP).
