Claim:
1. A method for a user equipment controlling handover between cells in a cellular network, the method comprising: estimating, by the user equipment, a risk of an ineffective handover for the user equipment; and when said estimated risk is above a threshold, changing, by the user equipment, value of at least one handover trigger parameter for the user equipment to reduce a future risk of an ineffective handover by the user equipment, wherein said changing includes changing a value of a Time To Trigger parameter; if said changing of the value of the Time To Trigger parameter does not lead to a next effective handover for the user equipment, changing a value of a handover Power Hysteresis parameter; if said changing the value of the handover Power Hysteresis parameter does not lead to a next effective handover for the user equipment, changing both the value of the Time To Trigger parameter and the value of the handover Power Hysteresis parameter.
