  • Method and apparatus for retransmitting packet data between base station controller and base transceiver system in a mobile communication system
    Publication number: 20030086427
    Abstract: A method and apparatus for retransmitting packet data lost during its transmission from a BSC to a BTS in a mobile communication system. The BTS sequentially receives packets from the BSC and determines whether there is a lost packet. When packet loss is detected, the BTS buffers packets received after a lost packet and requests a retransmission of the lost packet to the BSC. The BSC retransmits the lost packet to the BTS in response to the retransmission request. The BTS rearranges the retransmitted packet and the buffered packets according to the right order and transmits the rearranged packets to an MS.
