Abstract
This document describes techniques and devices for informing an upper layer of barring alleviation for multiple access classes. In some situations, a radio resource control (RRC) layer of a user equipment (UE) can provide to an upper layer of the UE a barring message that indicates at least two access classes are barred in response to receiving a rejection message from a random access network (RAN). Responsive to the RRC layer determining that the at least two access classes are no longer barred, the RRC layer can provide the upper layer an alleviation message that indicates barring of the least two access classes is alleviated. By informing the upper layer of multiple access classes using the alleviation message, miscommunications regarding barring alleviation of the access classes can be avoided between the RRC layer and the upper layer.
