Metrics for traffic steering in a wireless network

User Equipment (UE) comprising:

• a first transceiver to connect to a cellular access network, wherein the cellular access network includes a 3rd Generation Partnership Project (3GPP) access network;
• a second transceiver to connect to a non-cellular access network;
• and
• processing circuitry to:
• receive traffic routing rules, from an Access Network Discovery and Selection Function (ANDSF) device, via the cellular access network or the non-cellular access network;
• receive traffic steering metrics relating to network conditions associated with the non-cellular access network, the traffic steering metrics including:
• a first traffic steering metric relating to a channel utilization of a link between the UE and the non-cellular access network, and
• a second traffic steering metric relating to an uplink or downlink data rate of a link between the non-cellular access network and an external network, wherein the external network is a network external to the non-cellular access network;
• determine whether to steer traffic to the non-cellular access network based on the first traffic steering metric and the second traffic steering metric;
• and
• steer traffic to the non-cellular access network based on a result of the determination of whether to steer traffic to the non-cellular access network.

A mobile device comprising:

• one or more radio transceivers to connect to a plurality of access networks, at least one of the plurality of access networks including a wireless local area network (WLAN) access network;
• a non-transitory memory device storing a plurality of processor-executable instructions;
• and
• a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the processor to:
• process traffic routing rules, received from an Access Network Discovery and Selection Function (ANDSF) device;
• determine metrics relating to network conditions associated with the plurality of access network, the metrics including:
• a first metric relating to channel utilization of a link connecting the mobile device to the WLAN, and
• a second metric relating to an uplink or downlink data rate of a link connecting the WLAN to a wide area network (WAN), wherein the WAN is an external network to the WLAN;
• and
• steer network traffic over the plurality of access networks based on the first and second metrics, and based on the traffic routing rules received from the ANDSF.
