Abstract
Following radio link failure (RLF) of a radio link between a cellular internet-of-things (CIoT) user equipment (UE) and a source access node (nodeB) during a data transfer operation over a control plane between a mobility management entity (MME) of a narrow-band IoT (NB-IoT), a radio link is recovered by transmitting an RLF message from the CIoT UE to the MME of the NB-IoT network via a target nodeB, the target nodeB being different from the source nodeB. The RLF message is protected using a key associated with a non-access stratum (NAS) security context previously established between the CIoT UE and the MME of the NB-IoT network. The MME of the NB-IoT network can retrieve data that failed to be delivered to the CIoT UE due to the RLF during the data transfer operation over the control plane and provide said data to the UE via target nodeB.
