Abstract:
A mobile station is configured to transmit a sequence of data packets over a wireless network. The station includes a data sequence expander. The expander receives an indication of a pending hand-off for the mobile station from a first network access point to a second network access point and estimates an amount of time prior to occurrence of the hand-off. The expander inserts a number of delay packets into the sequence of data packets in response to receiving the indication of the pending hand-off. The number of delay packets is determined based on the estimated amount of time prior to the occurrence of the hand-off such that the insertion of the delay packets into the sequence of data packets will cause a delay that corresponds to the amount of time prior to occurrence of the hand-off.
