A Novel Cell Reselection Method in the Scenario of Multi-RAT

In order to reduce the number of unnecessary UE (User Equipment) cell reselection in Multi-RAT (Multi-Radio Access Technology) that consists of 2G, 3G and LTE for energy saving, a new method on procedure of cell reselection according to UE preference based on priority level is proposed in this paper. Later, this method will impact the measurement action and UE energy saving. The simulation results prove that the proposed scheme shows significant performance improvement on reducing the number of cell reselection and also UE power consumption.
