20090098874 | NARROW BEAM HANDOVER - Handover is a main function that is used to support mobility in the network. In a cellular communication network having adaptive antennas for enabling narrow beam operation, a network control unit sends a radio link setup request to a selected cell-serving network unit for configuration of a new serving radio link. Before responding to the radio link setup request the cell-serving network unit performs uplink measurements with respect to the mobile unit, and a narrow target beam is selected within a cell served by the cell-serving network unit based on these measurements. The cell-serving network unit then configures the new serving radio link for the considered mobile unit directly with the selected narrow target beam. Consequently the system can perform the handover procedure using narrow beams only, without first establishing the radio link with a cell-wide beam and then reconfiguring the radio link onto a narrow beam. | 04-16-2009 |

As a result, the average number of servers held in sets is reduced in a typical network that comprises a plurality of user equipments moving at different speeds, compared to a situation in which the threshold is set irrespective of the motion of a user equipment. A reduction in the average number of servers held in sets of servers for serving the user equipment has the benefit of reducing data traffic loading in a backhaul network, since the need to send duplicated data to each member of sets of servers is reduced and/or increasing network capacity, since the radio resource is used more efficiently because the proportion of servers sending duplicate data is reduced. | 06-25-2009 |
