20090059861 | BLIND HANDOVER USING LOAD COMPENSATED MEASUREMENTS - A method of initiating handover in a cellular radio system with CDMA access technology. A mobile station is present in a serving cell and handover should be made from a serving cell to a target cell. Before the handover is made the signal quality from the target cell is estimated. The mobile measures the signal quality, preferably Ec/Io of the pilot tone, from the serving cell. An RNC node calculates the estimated signal quality as a function of the measured signal quality, a load dependent quantity at the serving and target cells and decides to initiate the handover when the estimated signal quality at the target cell is better than a predefined minimum value or is better than the measured signal quality. As load dependent quantity the total output transmission powers P | 03-05-2009 |

20100330999 | Handover Support in Radio Communications - User equipment is to be handed over from a source cell to a target cell in a radio communication network. The user equipment is assigned dedicated uplink resources in the source cell, and a handover candidate cell is prepared for receiving the user equipment by obtaining information about the assigned dedicated uplink resources in the source cell. A radio base station for the handover candidate cell is listening for user equipment transmissions and determines, when receiving a user equipment transmission, whether the received user equipment transmission can be detected based on information about the assigned dedicated uplink resources in the source cell in order to assess if the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. The radio base station for the handover candidate cell initiates a handover procedure for the user equipment if it is assessed that the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. In this way, handover can be initiated and completed even if the serving radio base station of the source cell cannot receive a handover-triggering measurement report from the UE. | 12-30-2010 |
