Abstract:
1. A system for interconnecting an end user machine with a server for the transmission of data comprising: first and second base stations connected to the server; a subscriber unit connected to the end user machine and normally using a first wireless path with the first base station, the subscriber unit using a second wireless transmission path with the second base station when handed off from the first station to the second base station; means associated with the subscriber unit for initiating a first control signal signifying the start of a handoff and a second control signal signifying the completion of the handoff; means for establishing a single connection governed by TCP protocols between the end user machine and the server, the receiving of data packets from the server by the end user machine causing the generation of first actual acknowledgment signals each of which contains a first portion indicative of a packet received by the end user machine and a second portion indicative of the size of a receiving window of the end user machine; first intercepting means associated with the first base station for intercepting one or more successive first actual acknowledgment signals; means coupled to the first intercepting means and responsive to the first control signal for generating a first simulated acknowledgment signal whose first portion matches that of an intercepted first actual acknowledgment signal and whose second portion contains a value that indicates data transfer on the connection governed by TCP protocols is paused; and means for applying the first simulated acknowledgment signal to the server.
