Abstract:
The present invention relates to a method, a base station and an interface for handover in a wireless communication network. Handover is initiated when the signal quality falls below a predetermined value. Random access serves as an uplink procedure to enable the UE to make handover from a first base station (eNodeB) to a suitable second base station (eNodeB). In the present invention, random access parameters are exchanged between second and first base station before said first base station signals said random access parameters to said user equipment.
