Title: Method of asynchronous communication mode support based on CORBA for multi-service switching system
Inventor: BAEK UI HYEON
IPC: H04L12/28
Filed: 2000-12-26
Abstract: PURPOSE: An asynchronous communication mode supporting method in an open multi-service switching system is provided to improve a call processing performance of an overall system by providing a service of an asynchronous communication mode in response to a request of a non-real time service with a low priority, and reduce an initial investment cost of a communication provider by reducing the number of host systems for a high-priced switch control. CONSTITUTION: In order to request a service in an asynchronous communication mode, a lowermost priority order is set to render an operation and management software block to perform a specific function and a corresponding function containing address information for an implementation function and a turnaround function is called(201). A type for a parameter transmitted from the operation and management block and a data are interpreted to marshal it to a general inter-operability protocol(GIOP) of a middle ware and a GIOP request message is transmitted to an object broker(202). The object broker-A interprets the GIOP request message and transmits information for setting a TCP-based stream to transmits a message through the object broker and the Internet of a system in which the implementation function of the service request is positioned(203). In case that a path for a corresponding port has been activated or a stream set-up is not possible due to a system resource shortage, a remote system transmits error information, while in case that a stream set-up is possible, the remote system returns a response message and sets a stream, and accordingly, a communication path is formed for a message transmission between two systems(204). An asynchronous communication mode service request message obtained by containing an IIOP(Internet InterORB Protocol) header information in the GIOP request message is transmitted to an object broker process of the remote system through the connected path(205). The object broker process of the remote system interprets the received IIOP message and obtains skelton code information on the implementation function(206), and calls a skelton code for the implementation function(207).
