A method of supporting soft/softer handover mechanisms for High-Speed Uplink Packet Access (HSUPA) in a cellular communication network ( 1 ) with a plurality of base stations ( 2.1, 2.2 ), wherein said handover mechanisms include establishing an additional link to at least one additional network cell from a User Equipment (UE) ( 3 ) capable of using HSUPA and linked to a serving network cell ( 2.1 a) via a first link. 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.
