Method and terminal for applying an extended access barring

摘要

Disclosed is a method for applying an extended access barring (EAB), the method performed by a machine type communication (MTC) device and comprising: recognizing, by an upper layer of the MTC device, a change from being operated in an override low priority to being operated in a low priority; informing, by the upper layer, a lower layer that the priority has been changed; and determining, by the lower layer, whether to apply the EAB, to handle at least one of an attach request, a tracking area update request, and a service request. If the EAB is applied, a RRC connection is barred.

1. A method for applying an extended access barring (EAB), the method performed by a machine type communication (MTC) device, the method comprising:
receiving, by the MTC device set to override a low priority, a non-access stratum (NAS) configuration Management Object (MO) including EAB information; and determining whether to apply the EAB based on the EAB information and a setting related to the low priority, to handle at least one of an attach request, a tracking area update request, and a service request; if the EAB is applied, except for satisfying a plurality of conditions, including a first condition specifying if the MTC device is configured to allow overriding EAB, a second condition specifying if the MTC device is set to override the low priority, and a third condition specifying if the MTC device receives an indication from an upper layer to override EAB, then indicating to a lower layer that the EAB applies for at least one of the attach request, the tracking area update request, and the service request, wherein it is determined that the EAB is applied if the setting is changed to the low priority from overriding the low priority, and wherein, if the EAB is applied, a radio resource control (RRC) connection is barred.
