Abstract

This method for controlling handover of a mobile station from a first cell (61) to a second cell (62) includes adjusting handover parameters in a manner so that, when the wireless quality of the first cell (61) at the position of the mobile station (5) is a first level, the lag time from when handover start conditions are met to when handover is started is shorter than that in the case when the wireless 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 failure and ping-pong / rapid handover are both reduced, and a mobile station that is expected to remain in a small-scale cell for at least a certain period of time can be efficiently accommodated in the small-scale cell.

Description

technical field

[0001] The present invention relates to handover control in cellular radio communications. Background technique

[0002] In various systems, TTT (Time To Trigger) is used to adjust the delay time from when a condition for a state transition from one operating state to another is satisfied to when the state transition is actually initiated. TTT is also called hold time or guard time in some cases. Typically, TTT is used to determine the period during which state transition conditions need to be maintained. Specifically, when the state transition condition is continuously satisfied for a longer time than TTT, the state transition is actually initiated. Therefore, with longer TTTs, state transitions are less likely to occur. By employing hysteresis using TTT, the frequently repeated ping-pong phenomenon of state transitions between two operating states can be prevented.

[0003] In cellular wireless communication, TTT is used as one of handover control param...
