Methods of operating a wireless terminal in a wireless communication network are discussed. A connection resume request may be transmitted from the wireless terminal to a base station of the wireless communication network. After transmitting the connection resume request, a connection resume message may be received at the wireless terminal from the base station. Responsive to receiving the connection resume message, reconfiguration of a connection with the base station may be performed, a security key for the connection with the base station may be provided, and a radio bearer may be resumed. After resuming the radio bearer, uplink data may be transmitted using the radio bearer. Related base station methods, network nodes, and wireless terminals are also discussed.
