Claim 19:
20. A method of operating a wireless communication network to serve a User Equipment (UE) that uses Transmission Control Protocol (TCP), the method comprising:
wireless access nodes wirelessly broadcasting pilot signals;
the UE wirelessly receiving the pilot signals over radios, measuring received signal strength of the pilot signals for each of the radios, and qualifying ones of the radios having a received signal strength that exceeds a strength threshold;
the UE retrieving TCP retransmission data from memory that indicates past TCP retransmission rates at past geographic locations for the qualified radios, calculating distances between a current geographic location of the UE and the past geographic locations, and determining estimated TCP retransmission rates for the qualified radios at the current geographic location based on the past TCP retransmission rates for the radios at the past geographic locations and the distances between the current geographic location and the past geographic locations;
the UE comparing the estimated TCP retransmission rates for the qualified radios at the current geographic location to a rate threshold and selecting one of the qualified radios having an estimated TCP retransmission rate below the rate threshold;
the UE wirelessly exchanging TCP packets with one of the wireless access nodes using the selected one of the radios; and
the one of the wireless access nodes exchanging the TCP packets with a network TCP controller.
