Abstract
A communication system includes a plurality of base stations and a user equipment, wherein the communication link is established between the user equipment and a source base station of the plurality of base stations. A method includes: selecting a target cell and a re-establishment cell of at least one candidate handover base station of the plurality on the basis of a measurement report, the measurement report comprising measurements of attributes of cells of the plurality of base stations for a handover; initiating a handover preparation by transmitting a request from the source base station to the at least one candidate handover base station, wherein the request indicates the target cell and the re-establishment cell; carrying out admission control on the target cell and on the re-establishment cell; initiating the handover by transmitting a handover request acknowledgement from the at least one candidate handover base station to the source base station.
