Abstract:
1. For use in a data communication network including a wireless link for the transfer of data packets from a first machine to a second machine, the wireless link having a multitude of base stations which may be selectively designated to receive data packets from the first machine and a subscriber unit connected to the second machine for receiving data packets from a selectable one of the base stations, a method of maintaining data throughput during a handoff from a first one of the base stations to a second one of the base stations as requested by the subscriber unit, which comprises the steps of: uniquely designating only the first and second base stations for simultaneous receipt of the data packets from the first machine in response to the handoff request; storing the data packets received by the second base station after such handoff request but before handoff is executed; and forwarding a selected subset of the stored data packets to the subscriber unit after handoff is executed.
