The invention relates to methods for (re)attaching a UE to a 3GPP access network and for storing bearer context information of a UE upon handover from a 3GPP access network to a non-3GPP access network. Furthermore, the invention relates to 3GPP network nodes, such as mobility management entity, serving gateway and packed data gateway, and a UE that are specially adapted to perform these methods. In order to decrease of the delay time during (re)attachment of a UE to a 3GPP access network, the invention proposes to maintain context information on data bearer(s) of a UE within the 3GPP access network and the UE, while the UE is not attached to the 3GPP access network, so that data bearer context information for this UE is available and can be used for the (re)activation of data bearer(s) once the UE is attaching to the 3GPP access network again.
