1. A method of operating a wireless communication device to transition between wireless communication networks comprising:

  • in a wireless transceiver system, exchanging first wireless communication signals with a Long Term Evolution (LTE) network for an application in the wireless communication device;

    in the wireless transceiver system, transitioning from exchanging the first wireless communication signals with the LTE network to exchanging second wireless communication signals with at least one non-LTE base station associated with a non-LTE network for the application in the wireless communication device, wherein the second wireless communication signals identify LTE network status data;

    in a processing system, processing the LTE network status data to estimate an LTE network data rate;

    determining whether the LTE network is preferable over the non-LTE network based on a data requirement of the application, a current data rate of non-LTE network data, and the LTE network data rate;

    in the processing system, if the LTE network is preferable over the non-LTE network, processing the data requirement of the application, the current data rate of non-LTE network data, and the LTE network data rate to select an eNodeB sector and frequency carrier on the LTE network;

    in the wireless transceiver system and after selecting the eNodeB sector and frequency carrier, transmitting a notification message to the non-LTE network indicating a transition from the non-LTE network to the LTE network, wherein the notification message comprises an instruction to preserve an internet protocol (IP) address for the wireless communication device;

    in the wireless transceiver system and after transmitting the message, transitioning to idle mode and subsequently transitioning from the idle mode to active mode;

    in the wireless transceiver system and after transitioning from the idle mode to the active mode, exchanging third wireless communication signals with the LTE network for the application using the eNodeB sector and frequency carrier on the LTE network.
