Abstract
A method of controlling handover of a mobile station () from a first cell () to a second cell () includes adjusting a handover parameter so that, when radio quality of the first cell () at a position of a mobile station () is a first level, lag time from when a handover initiation condition is satisfied to when the handover is initiated is shorter than when the radio quality of the first cell is a second level that is higher than the first level. As a result, for example in HCS (HetNet), handover failures and ping-pong/rapid handovers can be reduced, and a mobile station expected to stay in a small-scale cell for at least a certain period of time can be efficiently accommodated in a small-scale cell.
