METHOD FOR TRANSMITTING VOICE DATA IN REAL TIME AT OPEN MULTISERVICE SWITCHING SYSTEM

摘要

PURPOSE: A method for transmitting voice data in real time at an open multiservice switching system is provided to reduce load of the switching system by providing a voice data real-time transport service. CONSTITUTION: An ORB core of a CORBA core receives coded voice data through a voice codec for marshalling the voice data into a GIOP(General Inter-Operability Protocol)(210). A type of a message to be served is inspected(221). It is judged whether the type of the message is voice data to be transported in real time(223). The performance of a system and a state of a network are inspected(225). The data is compressed and real-time transport protocol header information is generated(225). An IIOP transmits the voice data in real time through real-time transport protocol connection formed between a client and a server system(240). The compressed voice data is restored by using a real-time data restoring algorithm(250).
