摘要： A handover method is provided, in which a measure of signal strength is obtained between a user terminal and each of one or more candidate cells, relative to signal strength between the user terminal and a source cell. For candidate cells, a threshold is set that depends on a measure of loading of the source cell and a measure of loading of the candidate cell. For the target cell, a particular candidate cell is identified for which the measure of signal strength exceeds the threshold set for that particular cell. The user terminal is connected to the target cell. In specific embodiments, the threshold for each candidate cell depends on a load differential between the source cell and the candidate cell.

The proposed method comprises the steps of: upon detection of a soft/softer handover request from the user equipment (3), checking by a serving base station (2.1) of the plurality of base stations if at least a first predefined processing capacity is available at the additional network cell for allowing the requested handover; if said first processing capacity is available, controlling of said handover by means of the serving base station (2.1), else if only a second predefined processing capacity lower than the first predefined processing capacity is available, sending an information message to the User Equipment (3) from the base station (2.1, 2.2) controlling the additional network cell upon reception of data from the User Equipment (3). In this way, soft/softer handover and Relative Grant mechanisms are supported in the context of HSUPA.

摘要： A handover method is provided, in which a measure of signal strength is obtained between a user terminal and each of one or more candidate cells, relative to signal strength between the user terminal and a source cell. For candidate cells, a threshold is set that depends on a measure of loading of the source cell and a measure of loading of the candidate cell. For the target cell, a particular candidate cell is identified for which the measure of signal strength exceeds the threshold set for that particular cell. The user terminal is connected to the target cell. In specific embodiments, the threshold for each candidate cell depends on a load differential between the source cell and the candidate cell.
