The present invention relates to a relocation method, system and network
element for changing a serving radio resource control entity After an
initial operating state in which a user equipment (30) has radio links
with a serving network element (20) and a drift network element (21)
supporting said serving network element (20) with a wireless connection,
the serving network element (20) transmits a relocation-specific
information to a target network element (22). Based on the
relocation-specific information, the target network element (22)
establishes a link to the drift network element (21), such that the drift
network element (21) can receive user traffic from both the serving
network element (20) and the target network element (20). Then, the radio
resource control is relocated to the target network element (20). The
relocation-specific information may comprise an identifier or a list of
identifiers of drift network elements. Thus, existing soft handover
techniques can be enhanced by allowing a user plane connection to be
maintained with drift network elements. Thereby, any amount of drift
network elements can be kept, with improved radio performance as a
consequence.
