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 a first metric calculated based on a percentage signal strength determined based on a received signal strength of the non-cellular access network relative to a reference signal strength associated with the non-cellular access network, and a metric relating to a mobility of the UE with respect to network coverage of the non-cellular access network. The UE may route traffic to the non-cellular access network based on the first traffic steering metric and the second traffic steering metric.
