FIELD: radio engineering, communication.
SUBSTANCE: invention relates to the search for radio access technologies (RAT). The methods comprise performing higher priority radio access technology (RAT) searches in areas having a plurality of overlapping RAT, such as Global System for Mobile communications (GSM) and Long Term Evolution (LTE). According to certain aspects, user equipment (UE) may be configured to periodically search for higher priority RAT in neighbouring cells. According to certain aspects, upon finding a higher priority RAT cell, the UE may be further be configured to evaluate, or "pre-evaluate", criteria for cell reselection from the found cell to the currently camped cell, while still camped on the current cell. The UE may be configured to decide whether or not to switch to the found cell based on the evaluation.
EFFECT: managing switching between cells using different RAT, with elimination of problems associated with interaction of old RAT and new RAT.
