<p>The invention concerns a method of performing a handover (1424) of a wireiess packet-based connection between a user equipment (4) and a core network (3) from a source radio access network (1) with a first layer two technology to a target radio access network (2) with the same or a different iayer two technology. In the user equipment (4) two radio interfaces (41, 42) are provided, one interface (41) serving as a source radio interface with the source radio access network (1) and the other interface (42) serving as a target radio interface with the target radio access network (2). A wireless connection (24) between the user equipment (4) and the target radio access network (2) is established before releasing a wireless connection (14) between the user equipment (4) and the source radio access network (1). The same IP address is configured on each of the two radio interfaces (41, 42) during the time period of parallel existence of the two wireless connections (14, 24). The handover process (1424) is executed by using Proxy Mobile IP layer three handover processes and controlled by multi- standard mobility management entities (40, 100, 200) provided in the user equipment (4) and the source and target radio networks (1, 2).</p> |
