Abstract: The present invention provides a method and system for providing a SIP based Instance Messaging (IM), and an IM proxy server therefor. An IM proxy server for performing a proxy function in a mobile communication network is configured to provide an IM service between a mobile terminal lacking an SIP function and an IM server. Further, the IM proxy server converts an IM message received from the mobile terminal into a corresponding SIP message mapped thereto, transmits the SIP message to the IM server through a call session control server, converts an SIP message received from the IM server through the call session control server into an IM message recognizable by the mobile terminal, and transmits the IM message to the mobile terminal, thus providing the SIP based IM service to the mobile terminal lacking an SIP function.

Abstract: An arbitration switching system and a method of arbitration switching in a high-speed packet switching system uses a subscriber input/output device, an arbitration switching system and a parallel common bus part for the purpose of point-to-point communication point-to-multipoint communication and transferring packets generated in each node. A system bus structure is based on a parallel common bus type. Furthermore, to accommodate high-speed arbitration switching, operations such as polling, arbitration and switching are processed in parallel. Therefore, bus use efficiency is high, and a bus-extension can be easily achieved. A star LAN may be realized because broadcasting and multicasting are supported. An internal high-speed network for interlock in large-scaled communication systems that need high-speed switching can also be provided.

Abstract: Provided is an apparatus and method for transmitting and receiving a streaming service. An inter-arrival jitter may correspond to a delay variation in arrival time between TCP packets arriving at an apparatus for receiving the streaming service. The apparatus for receiving the streaming service may determine a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet is input to a T-STD buffer model. Based on the de-jitter buffering time, an initial playout delay lime at the apparatus for receiving the streaming service may be determined.
