Abstract
A handover method includes the steps: (1a) detecting, at a serving node, signal quality of a signal transmitted from the serving node to a user equipment (UE) being worse than a predefined threshold; (1b) identifying, at the serving node, node(s) transmitting to the UE the strongest signals interfering with signals being transmitted to the UE; (1c) sending, by the serving node, a request for starting an inter-cell interference coordination scheme; (1d) rescheduling, by the node(s) identified in step (1b), users currently being served by the node(s); (1e) informing, by the node(s) identified in step (1b), the serving node of the UE which resources have, been reserved in step (1d); (1f) scheduling, by the serving node, the UE to the resources reserved in step (1d); (1g) starting, by the serving node, handover of the UE from the serving node to a target node; and (1h) completing the handover of the UE.
