Method and device to provide access control for a user equipment to manage access barring timers
An access control method and a user equipment are provided in the present invention. The access control method in a user equipment includes: determining, according to a status of the user equipment, a corresponding access control parameter to execute access control; if a result of the access control is access barring, then starting different access barring timers corresponding to different user equipment states, or starting the same access barring timer in the different user equipment states; and determining a duration of the started access barring timer according to the corresponding access control parameter.
1. An access control method for a user equipment (UE), the access control method comprising:
executing an access control check for an access category;
starting an access control timer when a result of the access control check is access barring; and
stopping the access control timer that is running when the UE receives a Radio Resource Control (RRC) reconfiguration message or an RRC release message.
2. The access control method according to claim 1 , further comprising:
stopping the access control timer that is running when the UE initializes an RRC connection re-establishment procedure.
3. The access control method according to claim 1 , wherein the RRC reconfiguration message includes information for synchronizing to a cell.
4. The access control method according to claim 1 , further comprising:
when the access control timer stops running, notifying an upper layer that access barring for the access category is alleviated.
5. A user equipment comprising a processor, the processor configured to:
execute an access control check for an access category;
start an access control timer when a result of the access control check is access barring; and
stop the access control timer that is running when the UE receives a Radio Resource Control (RRC) reconfiguration message or an RRC release message.
6. The user equipment according to claim 5 , wherein the processor is further configured to stop the access control timer that is running when an RRC connection re-establishment procedure is initialized.
7. The user equipment according to claim 5 , wherein the RRC reconfiguration message comprises information for synchronizing to a cell.
8. The user equipment according to claim 5 , wherein, when the access control timer stops running, the processor is further configured to notify an upper layer that access barring for the access category is alleviated.
9. The access control method according to claim 2 , further comprising:
when the access control timer stops running and after the UE initializes the RRC connection re-establishment procedure, notifying an upper layer that access barring for the access category is alleviated.
10. The access control method according to claim 3 , further comprising:
when the access control timer stops running and the RRC reconfiguration message includes the information for synchronizing to the cell, notifying an upper layer that access barring for the access category is alleviated.
11. The user equipment according to claim 6 , wherein when the access control timer stops running and after the RRC connection re-establishment procedure is initialized, the processor is further configured to notify an upper layer that access barring for the access category is alleviated.
12. The user equipment according to claim 7 , wherein when the access control timer stops running and the RRC reconfiguration message comprises the information for synchronizing to the cell, the processor is further configured to notify an upper layer that access barring for the access category is alleviated.
