Abstract
Methods and devices in a cellular radio system for handling repeated handovers of a user equipment between a pair of cells is provided. It is determined if the user equipment is in one of two states, moving state or stationary state. Based on the determination different actions can be taken. For example threshold optimizations for reducing repeated handover may only be applied to a user equipment determined to be in a stationary state or a user equipment determined to be in a stationary state to can be nailed to the best cell of said pair of cells by not allowing the user equipment to handover to the other cell of said pair of cells.
Claims16
A method in a cellular radio system for handling repeated handovers of a user equipment (UE) between a pair of cells, the method comprising the steps of:
- determining if the UE is experiencing repeated handovers, and if so determining whether the UE is in a moving state or a stationary state;
- and
- responsive to determining the UE is in the stationary state, either applying threshold optimizations to the UE for reducing repeated handover of the UE, or constraining the UE to the best cell of said pair of cells by preventing handover of the UE to the other cell of said pair of cells.
A device for a cellular radio system adapted to handle repeated handovers of a user equipment (UE) between a pair of cells, the device comprising processor circuitry configured to:
- determine if the UE is experiencing repeated handovers, and, if so, determine whether the UE is in a moving state or a stationary state;
- and
- responsive to the UE being in the stationary state, to apply threshold optimizations to the UE for reducing repeated handover of the UE, or to constrain the UE to the best cell of said pair of cells by preventing handover of the UE to handover to the other cell of said pair of cells.
