Abstract: A method for controlling a rate of a voice service in a mobile communication system supporting the voice service via a packet network. The method includes the steps of receiving a control message at a terminal from a radio network controller (RNC); if the control message indicates control of a downlink rate, determining a downlink rate according to the control message; setting a Change Mode Request (CMR) field of an uplink Voice over Internet Protocol (VoIP) packet according to the downlink rate, and transmitting the uplink VoIP packet from the terminal to the RNC; if the received control message indicates control of an uplink rate, determining an uplink rate according to the control message; and generating an uplink VoIP packet including uplink voice data generated according to the determined uplink rate and frame type (FT) information indicating the determined uplink rate, and transmitting the uplink VoIP packet from the terminal to the RNC.

Abstract: A method for transmitting packet data units Packet Data Units (PDUs) at a PDU transmitter in a communication system is provided. The method includes transmitting a first PDU comprising a PDU header and a data portion, receiving Negative Acknowledgement NACK information for the first PDU, segmenting the first PDU to form one or more PDU segments if a size of a second PDU for retransmission is smaller than a size of the first PDU, wherein each of the one or more PDU segment comprises a PDU segment header and a data portion, and transmitting the one or more PDU segment to a PDU receiver.

Abstract: A method and apparatus for performing a L3 handover between CNs in a packet-switched network are provided. When a UE moves from an old RAN to a new RAN, the UE sends a measurement report message including cell information to the old RAN. The old or new RAN determines whether to perform a L3 handover. If the L3 handover is required, a tunnel is established between the new RAN and a new CN. The UE performs a handover from the old RAN to the new RAN, without establishing a tunnel between the new RAN and an old CN. Upon detection of the movement of the UE, the new RAN sends a L2 handover complete message to the old RAN. After moving to the new RAN, the UE acquires a new IP address, performs the L3 handover, and communicates with the new CN through the new RAN.
