Abstract

The invention therefore relates to a method, a first Mobility Control Node and a second Mobility Control Node for context handling when a user equipment, UE, moves from a previous Access Network, AN, to a present AN. The ANs are adapted to communicate with a Core Network, CN, and the UE is adapted to communicate wirelessly with the AN's. The method comprises the steps of: the UE detecting that it has entered a Mobility Area, MA, belonging to the present AN, said MA not being registered with the CN, the UE initiating a Mobility Area Update, MAU, procedure in response to the detection by sending a MAU Request message comprising an UE Temporary ID to a Radio Access Node, RAN, the RAN adding a Mobility Area Identity, MAI, to the Request message and forwarding the message to a first Mobility Control Node, MCN, responsible for the present AN, the first MCN deriving one second MCN from the UE Temporary ID and sending a context request message to said second MCN.
