Method of cell selection in heirarchical cell structure based on cell quality
A cell selection method where, if a hierarchical cell structure (HCS) is used, a first ranking procedure is performed if the UE has low mobility, and a second ranking procedure is performed if the UE has high mobility. When the UE has low mobility, the first ranking procedure is performed for all measured cells that have a highest HCS priority among those cells that fulfill a criterion S and a criterion H≧0, or the ranking procedure is performed for all measured cells regardless of HCS priorities if no cell fulfills the criterion S and the criterion H≧0. When the UE has high mobility, the second ranking procedure is performed for all measured cells, and if there are cells with lower HCS priority than the serving cell that fulfills the criterion S and the criterion H≧0, the ranking procedure is performed for all cells that have the highest HCS priority.
