Method and apparatus for restricting access of devices
Embodiments of the present application are directed to a method and apparatus for restricting access of devices. The receiving cell access related method may include: receiving cell access related information; and information performing an access control based on the cell access related information and a device type of a user equipment (UE).
1. A method performed by a user equipment (UE), the method comprising:
receiving, from a network, cell access related information including first access control parameters;
identifying an access identity (AI) and an access category (AC) of the UE;
identifying the UE as a reduced capabilities device, according to one of the identified AC or the identified AI;
determining second access control parameters corresponding to an AC of a non-reduced capabilities device according to the first access control parameters and a mapping table, wherein the mapping table defines a mapping between ACs of the non-reduced capabilities device and ACs of the reduced capabilities device; and
performing an access control based on the cell access related information and a device type of the UE using the second access control parameters corresponding to the AC of the non-reduced capabilities device.
2. The method of claim 1 , wherein the cell access related information includes indication information which indicates whether devices with a device type of reduced capabilities are allowed to access a cell or are barred from accessing the cell, and wherein the performing the access control is further based on the indication information.
3. The method of claim 1 , wherein the cell access related information is received as part of a broadcast message.
4. The method of claim 1 , wherein the performing the access control further comprises checking whether an access is barred by using the first access control parameters.
5. The method of claim 1 , wherein the mapping table is received through a broadcast message or is preconfigured.
6. The method of claim 2 , wherein the indication information comprises a single bit.
7. The method of claim 3 , wherein the broadcast message comprises a system information block (SIB) or a master information block (MIB).
8. The method of claim 1 , wherein the performing the access control further comprises checking whether an access is barred based on applying a scale factor to the first access control parameters.
9. The method of claim 1 , wherein the performing the access control further comprises checking whether an access is barred based on applying a scale factor to the second access control parameters.
10. The method of claim 9 , further comprising receiving the scale factor as part of a broadcast message.
11. A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to cause the UE to:
receive, from a network, cell access related information including first access control parameters;
identify an access identity (AI) and an access category (AC) of the UE;
identify the UE as a reduced capabilities device, according to one of the identified AC or the identified AI;
determine second access control parameters corresponding to an AC of a non-reduced capabilities device according to the first access control parameters and a mapping table, wherein the mapping table defines a mapping between ACs of the non-reduced capabilities device and ACs of the reduced capabilities device; and
perform an access control based on the cell access related information and a device type of the UE using the second access control parameters corresponding to the AC of the non-reduced capabilities device.
12. The UE of claim 11 , wherein the cell access related information includes indication information which indicates whether devices with a device type of reduced capabilities are allowed to access a cell or are barred from accessing the cell, and wherein the access control is further based on the indication information.
13. The UE of claim 11 , wherein the cell access related information is received as part of a broadcast message.
14. The UE of claim 11 , wherein wherein, to perform the access control, the at least one processor is further configured to cause the UE to check whether an access is barred by using the first access control parameters.
15. The UE of claim 12 , wherein the indication information comprises a single bit.
16. The UE of claim 13 , wherein the broadcast message comprises a system information block (SIB) or a master information block (MIB).
17. The UE of claim 11 , wherein, to perform the access control, the at least one processor is further configured to cause the UE to check whether an access is barred based on applying a scale factor to the first access control parameters.
18. The UE of claim 11 , wherein, to perform the access control, the at least one processor is further configured to cause the UE to check whether an access is barred based on applying a scale factor to the second access control parameters.
19. The UE of claim 18 , wherein the at least one processor is further configured to cause the UE to receive the scale factor as part of a broadcast message.
20. An apparatus, comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to cause the apparatus to:
transmit cell access related information to a user equipment (UE) configured to perform an access control based on the cell access related information and a device type of the UE; and
transmit, to the UE for the access control, a mapping table that defines a mapping between access categories (ACs) of a non-reduced capabilities device and ACs of a reduced capabilities device.
