Abstract
Various examples pertaining to improvement for incorrect key set identifier (KSI) handling in mobile communications are described. An apparatus (e.g., user equipment) receives from a wireless network an authentication challenge after the processor having completed an authentication and key agreement (AKA) procedure with the wireless network. The apparatus detects an error in the authentication challenge and handles the error in the authentication challenge. For example, the apparatus can reject the authentication challenge responsive to detecting the error. Alternatively, the apparatus can accept the authentication challenge.
