Patent ID: 11589235

Abstract:
A network node (30A, 30B) is configured for use in a wireless communication network (10). The network node (30A, 30B) is configured to acquire radio access capability information (28) of a wireless device (14). The radio access capability information (28) of the wireless device (14) indicates radio access capabilities of the wireless device (14). The network node (30A, 30B) is configured to determine if the wireless communication network (10) received the radio access capability information (28) of the wireless device (14) before access stratum security (24) was activated for the wireless device (14). If the wireless communication network (10) received the radio access capability information (28) of the wireless device (14) before access stratum security (24) was activated for the wireless device (14) according to that determination, the network node (30A, 30B) is configured to re-acquire the radio access capability information (28) of the wireless device (14) after access stratum security (24) is activated for the wireless device (14).
