Abstract:
1. A method comprising: detecting a device enhanced access barring (EAB) configuration by a user equipment (UE) in a mobile communication network, wherein the UE EAB configuration indicates whether the UE is configured with EAB such that the UE is subject to restriction of any EAB category; acquiring EAB information from a base station by the UE if the UE is configured with EAB, wherein the EAB information indicates whether barring is applied to a number of EAB categories and a number of access classes broadcasted via a system information block; performing enhanced access barring by the UE for radio resource control (RRC) connection based on the EAB information; and performing access class barring (ACB) for RRC connection if the UE is configured for ACB and is not barred by the enhanced access barring.
