The wireless transceiver performs wireless transmission and reception to and from a service network. The controller determines, during an ongoing Non-Access Stratum (NAS) procedure, whether a SECURITY MODE COMMAND message received from the service network via the wireless transceiver fails an integrity protection check and no RRC CONNECTION RELEASE message has been received from the service network via the wireless transceiver, or whether transmission of a SECURITY MODE COMPLETE message to the service network via the wireless transceiver has failed. Also, the controller locally releases a connection to the service network when the SECURITY MODE COMMAND message fails the integrity protection check and no RRC CONNECTION RELEASE message has been received, or when the transmission of the SECURITY MODE COMPLETE message has failed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatuses and methods for recovering from security mode command failures","description":"A mobile communication device including a wireless transceiver and a controller is provided.
