ABSTRACT:
The present invention relates to a method for performing handover in a communication network, wherein communication with a subscriber terminal (UE) having subscribed to said network is performed by the intermediate of at least one network entity (Node B) handling the communication of said subscriber terminal, upon a change of a communication state for said subscriber terminal within said network, which fulfills a predetermined handover trigger condition, a handover procedure is performed under control of a control entity (RNC) of the communication network, a handover procedure is defined by a handover signaling scenario (HO, HHO, SHO, SSTD) and at least one set of handover parameters per signaling scenario, the handover parameters define a respective handover trigger condition, a communication with a subscriber terminal belongs to a specific one of a plurality of traffic classes, and wherein at least one user class is defined per traffic class, the method comprising the steps of configuring a set of handover parameters and a handover signaling scenario per user class, and performing, upon detection that said handover trigger condition is fulfilled, the handover procedure for said subscriber terminal as defined by the configured handover signaling scenario and the configured set of handover parameters for the respective user class of the respective traffic class.
