Abstract
A user equipment UE selects between a first scanning mode and a second scanning mode using at least inputs of signal quality of a link with an access node and at least one of UE speed and network type of the access node. It then determines a scanning rate using the selected scanning mode and the UE speed, and detects and measures inter-frequency neighbor cells according to the determined scanning rate. In one example both modes the increase scanning rate for increased UE speeds, except that for the first mode speeds above Vt1 yield a zero scanning rate regardless of UE speed and for the second mode speeds above Vt2 yield a constant maximum scanning rate regardless of UE speed. In an embodiment the second mode is selected when the UE speed is >Vt1, and the signal quality is less than a predetermined minimum. Various other examples are detailed.
