Abstract: A wireless device performs a method for resuming a Radio Resource Control, RRC, connection. While in a power saving state, the wireless device monitors a paging 5channel. When the wireless device receives a paging message on the paging channel, it determines whether the paging channel includes a message enabling the wireless device to resume the RRC connection. If the paging channel includes a message enabling the wireless device to resume the RRC connection, the wireless device performs actions determined by said message.

The wireless device uses the one or more parameters to perform at least one action from any one or more of the following actions: receiving a mobile-terminated, MT, early data transmission, EDT, during a random access procedure; positively or negatively acknowledging the MT-EDT; and receiving a re-transmission of the MT-EDT.

Abstract: The proposed technology generally relates to interworking and integration of different radio access networks, and more specifically to carrier aggregation between different radio access networks such as a cellular radio access network, e.g. a 3GPP network, on one hand and a WLAN network such as Wi-Fi, on the other hand. Such tight interworking/aggregation of radio access networks puts new requirements on efficient handling of authentication and security aspects. The proposed technology provides methods, and corresponding network nodes, computer programs, carriers comprising such computer programs, and computer program products as well as arrangements to support carrier aggregation between different radio access networks.

Abstract: Methods, User Equipment, UE, (120) and source network node (111) for resuming a Radio Resource Control, RRC, connection to a target cell in a wireless communications network (100). The UE generates a security token using a set of input parameters, and sends a resuming request with the security token to a target network node (112) serving the target cell. When receiving the resuming request, the source network node generates a security token using a set of input parameters in the same manner as the UE. If the received security token is successfully verified when compared with the generated security token, the source network node provides to the target network node a UE context of the UE, to enable the target network node to resume the RRC connection.
