1. User Equipment (UE) comprising:

  • a first transceiver to connect with a cellular access network;

    a second transceiver to connect with a wireless local area network (WLAN); and

    processing circuitry to;

    receive a first threshold value, from a network device and via the cellular access network or the WLAN, relating to channel utilization of a link between the UE and the WLAN;

    receive a second threshold value, from the network device and via the cellular access network or the WLAN, relating to a data rate of a link between the WLAN and a Wide Area Network (WAN), wherein the WAN is an external Internet Protocol (IP) network to the WLAN and the UE;

    receive traffic routing rules, from an Access Network Discovery and Selection Function (ANDSF) device, via the cellular access network or the WLAN;

    determine a first metric measuring the channel utilization of the link between the UE and the WLAN;

    store a value of the determined first metric in a data structure maintained by the UE;

    determine a second metric measuring the data rate of the link between the WLAN and the WAN;

    store a second value of the determined second metric in the data structure maintained by the UE; and

    steer traffic between the cellular access network and the WLAN based on the first threshold value, the second threshold value, the value of the first metric, the value of the second metric, and the traffic routing rules.
