Enhanced attachment procedure for attaching a ue to a 3gpp access network

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