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.

Abstract
Metrics may be used by user equipment (UE) to steer traffic through different access networks or to provide access network mobility decisions. For example, in one implementation, a UE may determine metrics relating to network conditions associated with at least a non-cellular access network. The metrics may include receive a first value relating to channel utilization of a link between the UE and a WLAN; and a second value relating to a data rate of a link between the WLAN and a WAN.
