摘要： 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.

摘要： A method for handoff between packet data serving nodes (PDSNs) The method for handoff between packet data serving nodes (PDSNs) provides packet services to a mobile node. A new PDSN receives subscriber information of a mobile node from at least one or more old PDSNs forming a communications network. The new PDSN recognizes the mobile node moving into a concerned area of the new PDSN and then transmits recognition information on the mobile node to an old PDSN to which the mobile node was connected. All received information on the mobile node is transmitted by the old PDSN based on the recognition information. A communication channel is established with the mobile node based on the received information. In the method, handoff is performed without reestablishing PPP. Accordingly, handoff between PDSNs can be performed faster, reducing the time needed for establishing a PPP session with a terminal and for terminating a previously set up PPP session.
