Abstract
Solutions for accelerating cell search and selection by a user equipment (UE) include: detecting, by the UE, a network exit; determining, by the UE, a network reentry condition; based on at least mobility data for the UE and a network connectivity context history, determining, by the UE, using a machine learning (ML) component, a set of priority reentry cells; attempting network reentry with the set of priority reentry cells; and based on at least failing network reentry with the set of priority reentry cells, attempting network reentry with a cell search. In some examples, mobility data for the UE is also used for determining the set of priority reentry cells. By searching the set of priority reentry cells first , rather than starting with a blind search, the UE may save not only battery power, but also reconnect to the network more quickly, thereby improving the user experience.
