  • Patent number: 7200398
    Abstract: A method for handover execution in a wireless environment is provided that comprises communicating, by a mobile network, a handover command message to a physical layer of a mobile station to initiate a handover execution. The handover command message is received by the physical layer, which responds by tuning to a handed to frequency and by communicating physical layer bursts over the handed to frequency such that initial timing advance and power control setting characteristics are determined by the mobile network. The method also includes communicating a cease signal to stop communicating the bursts to the mobile station, which responds by ending the transmission of the bursts and by establishing a new communications link over the handed to frequency with the mobile network. The mobile station and mobile network may then couple to a voice or data path such that a wireless communication associated with the mobile station and the mobile network is facilitated.

  • Patent number: 6901116
    Abstract: A demodulator determines a time of arrival of an access signal. Access signals that do not result in a time of arrival are discarded. Upon obtaining a time of arrival, the access signal is equalized and a training sequence of bits in the equalized access signal is compared to a reference sequence of bits. A burst confidence metric is obtained in the comparison by summing the number of matching bits. The access signal is discarded if the burst confidence metric is less than a threshold number. A decoder performs a parity check on access signals that have a burst confidence metric exceeding the threshold number. The access signal is discarded if the parity check fails. Upon passing the parity check, the access signal is re-encoded and compared to its received version. If a number of errors from the comparison exceeds a bit error threshold, the access signal is discarded.
