Abstract

User Equipment (UE) may skip the Access Class Barring (ACB) procedure for specific services, such as MMTEL voice, MMTEL video, and SMS. In one implementation, NAS layer of a UE may: receive, from an upper layer relative to the NAS layer, a request for a particular service type that is being originated by the UE; receive an indication, from a Radio Resource Control (RRC) layer of the UE, that access to a cell, associated with the UE, is barred; and bypass the indication that access to the cell is barred, when the particular service type matches a predetermined set of service types. The bypassing may include: requesting that the RRC layer establish an RRC connection for the service request, and notifying the RRC layer that the request for the RRC connection corresponds to the particular service type.
