Abstract
Disclosed is a mobility management method for use in a cellular mobile communication system. The mobility management method is configured to save radio resources and provide a stable service by detecting a cell in which a dwell time of user equipment (UE) is short as an island cell and performing a direct handover (HO) to an appropriate cell without handing over the UE to the island cell. There are provided three methods including a base station-based method, a UE measurement-based method, and a UE history-based method according to how to measure a dwell time in which the UE stays in a cell, a component in which obtained information is received within a network, and how to process an HO using the information.
