A method for informing an upper layer of a user equipment of barring alleviation for multiple access classes, the method comprising the user equipment performing operations including: determining , at a radio resource control layer of the user equipment , that a first access class is not barred; sending , by the radio resource control layer , a first connection request message to a network , the first connection request message requesting permission to establish a first wireless connection associated with the first access class ; receiving , at the radio resource control layer , a rejection message from the network , the rejection message denying the request to establish the first wireless connection; responsive to receiving the rejection message , providing , from the radio resource control layer to the upper layer , a first barring message that indicates barring of at least the first access class and a second access class ; responsive to receiving the rejection message , activating , at the radio resource control layer , a common bar timer associated with the access classes identified in the first barring message ; responsive to the common bar timer becoming inactive , determining whether or not respective specific bar timers associated with at least the first access class and the second access class are inactive; responsive to determining that the respective specific bar timers associated with at least the first access class and the second access class are inactive, determining that the barring of at least the first access class and the second access class is alleviated; and providing , from the radio resource control layer to the upper layer , a first alleviation message that indicates alleviation of the barring of at least the first access class and the second access class . determining , at a radio resource control layer of the user equipment , that a first access class is not barred; sending , by the radio resource control layer , a first connection request message to a network , the first connection request message requesting permission to establish a first wireless connection associated with the first access class ; receiving , at the radio resource control layer , a rejection message from the network , the rejection message denying the request to establish the first wireless connection; responsive to receiving the rejection message , providing , from the radio resource control layer to the upper layer , a first barring message that indicates barring of at least the first access class and a second access class ; responsive to receiving the rejection message , activating , at the radio resource control layer , a common bar timer associated with the access classes identified in the first barring message ; responsive to the common bar timer becoming inactive , determining whether or not respective specific bar timers associated with at least the first access class and the second access class are inactive; responsive to determining that the respective specific bar timers associated with at least the first access class and the second access class are inactive, determining that the barring of at least the first access class and the second access class is alleviated; and providing , from the radio resource control layer to the upper layer , a first alleviation message that indicates alleviation of the barring of at least the first access class and the second access class . <EOS>
