The invention relates to a method for supporting a handover of a mobile station (1) from a first radio access unit (3, 8) of a wireless communication network (2) to a second radio access unit (4, 9) of a wireless communication network (2). In order to improve a context transfer in the case of a handover of the mobile station (1), the mobile station (1) transmits information about its activity state to the second radio access unit (4, 9) when it is to be handed over to the second radio access unit (4, 9). The invention relates equally to such a mobile station, to such a second radio access unit, to a wireless communication system comprising such a mobile station and such a second radio access unit, and to a software code causing the transfer of information at the mobile station.
