METHOD AND ARRANGEMENT IN A COMMUNICATION NETWORK

摘要

Method and arrangement in a node in a radio access network for use in improving a success ratio for hard handover of a downlink connection to a user equipment (110) between cells (132, 121) in the radio access network (110). The user equipment and the radio access (110) network are capable of engaging in diversity handover for uplink communications. The method comprises the steps of transmuting to the user equipment (110) information authorising the user equipment (116) Io take a decision on whether to initiate the downlink handover procedure, receiving from the user equipment information establishing a point in time for performing the downlink handover, initiating an activation of a source cell (121) and a target cell (132) in preparation for the downlink handover prior to the established point in time and performing the downlink handover in the radio access network (110) at the established point in time. Also, a method and arrangement in a user equipment (110) is presented.
