Abstract
A computing device (e.g., a mobile phone, a tablet computer, a laptop computer, a wearable device, etc.) may execute a scan reduction algorithm by skipping frequencies refarmed to radio access technology (RAT) that the computing device cannot camp on (hereinafter referred to as an “unsuitable RAT”) during frequency band scan. Per the scan reduction algorithm, the computing device may check (e.g., when performing an initial cell selection procedure) whether a candidate frequency range from a candidate band set is occupied by an unsuitable RAT by querying an occupied frequency repository. If the query results indicate that the candidate frequency range is not occupied, the computing device may search for a suitable cell. If the query results indicate that the candidate frequency range is occupied, the computing device may skip that frequency range when performing the frequency band scan, potentially saving time.
