Radio base station, method in a radio base station, relay station and method in a relay station

摘要

Methods and network nodes (110, 112), serving a user equipment (120), for deciding if a handover request of the user equipment (120) is to be sent to a candidate target network node (130-1, 130-2, 130-3). The methods comprise acquire (603) data-rate performance of a wireless link between the network nodes (110, 112) and the user equipment (120). The data-rate performance is compared (606) with a data-rate performance threshold value. If the acquired data-rate performance is lower than the data-rate performance threshold value, it is decided (607) to send the handover request of the user equipment (120) to the candidate target network node (130-1, 130-2, 130-3).

1. A method, in a radio base station serving a user equipment, for deciding whether a handover request of the user equipment is to be sent to a candidate target network node, the method comprising:
acquiring data-rate performance of a wireless link between the radio base station and the user equipment; comparing the acquired data-rate performance with a data-rate performance threshold value, wherein the data-rate performance threshold value is based on a previously determined throughput of a wireless link between at least one user equipment, via a relay node, and the radio base station or a neighboring radio base station; and deciding to send the handover request of the user equipment to the candidate target network node, in the event that the acquired data-rate performance is lower than the data-rate performance threshold value.
