Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of processing algorithms in a computer when transmitting a signal to a signal network, and more specifically, telecommunication using a distributed object architecture. In particular, the present invention relates to an operation transmission method and method to a network, and particularly to an operation transmission method and a method suitable for transmission of a requested operation in a communication system using a CORBA (Common Object Request Broker Architecture) bus which is a distributed object technology. Regarding the method.

[0002]

2. Description of the Related Art A conventional communication system in CORBA is shown in FIG. Client 2 on computer 1
When a request is issued to the ORB (Object Request Broker) 3 which provides a communication function, the method of the server 7 in the computer 6 is called by the communication between the ORB 3 and the ORB 4 via the telecommunication network 5.
When the method is called, the server 7 performs the requested process, sets a return value such as a process result, and returns the result as a response. Then, the return value is returned to the client 2 by communication via the electric communication network 5 of the ORB 4 and the ORB 3.

[0003]

Next, with reference to FIG. 6, an example in which the above-described conventional communication system in CORBA is applied to a configuration having a plurality of telecommunication networks will be described.

This is the case when it is necessary to send and receive signals to and from.

When the computer 8 sends an operation to the computer 9 of the other party who is communicating via the telecommunication network 14 through the client 11 and the ORB 13, the requested operation arrives at the server 17 through the ORB 16 in the computer 9. Here, the server 17 performs the requested process and returns a response. At that time, until the response arrives at the client 11 through the ORB 13 of the computer 8, the logic program 10
Cannot use the signal transmission / reception function unit 12 to transmit / receive signals to / from the telecommunication network 15.

Since the processing in the server 17 differs depending on the contents of the requested operation, when the client 11 requests the processing that takes a long time, the telecommunications network 1 waits for that time.
