Title:
The hand-over control method, a control device, an adjustment device, and a program
Document Type and Number:
Japanese Patent JP5907074
Kind Code:
B2
Abstract:
A method of controlling handover of a mobile station (5) from a first cell (61) to a second cell (62) includes adjusting a handover parameter so that, when radio quality of the first cell (61) at a position of a mobile station (5) 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.
