Abstract:

This disclosure relates to techniques for a wireless device to perform radio resource control procedures with improved security. The wireless device may establish a radio resource control connection with a cellular base station. A capability enquiry may be received from the cellular base station. The wireless device may determine how much capability information to provide in response to the capability enquiry based at least in part on whether access stratum security has been established, either in the current radio resource connection, or in a previous radio resource connection, between the wireless device and the cellular base station when the capability enquiry is received.
