Abstract
During the transition period from 4G and long-term evolution (LTE) to 5G technology, for 5G capable user equipment (UE), it is preferred to utilize non-standalone (NSA) cells that support 5G technology rather than LTE only cells. To enable such preference, a fingerprint database recording known neighboring NSA cells to LTE only cells and a flag for identifying NSA cells in the acquisition database of the UE can be used to prioritize searching for NSA cells on startup and to expedite reselection to an NSA cell when camping on LTE only cells. To avoid excess battery drain when camping on LTE only cells since searching for cells consumes significant power of the UE, a series of timers and a counter can be used to disable the NSA preferred feature if an NSA cell is not found after a reasonable search while camping on the LTE only cell.
