Method and apparatus for paging control
The present disclosure relates to methods and apparatuses. According to some embodiments of the disclosure, a method includes: receiving, at a user equipment, information indicating whether busy indication functionality is supported or not, wherein the busy indication functionality is associated with at least one of Core Network (CN) paging or Radio Access Network (RAN) paging. In addition, a cause value indicating busy indication between Xn interface can be used to determine whether the path switching should be performed or not.
1. A method performed by a user equipment (UE), the method comprising:

determining that the busy indication functionality is supported based on the information.
2. The method of claim 1 , wherein the information comprises an indicator having at least one bit, and the indicator indicates one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
3. The method of claim 1 , wherein the information comprises an information element (IE) indicating one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
4. The method of claim 3 , wherein a value of the IE is equal to an enumerated type true.
5. The method of claim 1 , further comprising:
determining that the busy indication functionality is supported when the information comprises parameters associated with the busy indication functionality.
6. The method of claim 5 , wherein determining that the busy indication functionality is supported comprises determining one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
7. The method of claim 1 , wherein the information is received via a non-access stratum (NAS) message, and the information indicates whether the busy indication functionality for the CN paging is supported.
8. The method of claim 1 , wherein the information is received via radio resource control (RRC) dedicated signaling, and the information indicates one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
9. The method of claim 8 , wherein the RRC dedicated signaling comprises a RRC release message comprising a suspend configuration information element (IE).
10. A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive information related to busy indication functionality of a network, wherein the busy indication functionality is associated with at least one of core network (CN) paging or radio access network (RAN) paging, and wherein the information related to the busy indication functionality indicates whether the busy indication functionality is supported for at least one of the CN paging or the RAN paging; and
determine that the busy indication functionality is supported based on the information.
11. The UE of claim 10 , wherein the information comprises an indicator having at least one bit, and the indicator indicates one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
12. The UE of claim 10 , wherein the information comprises an information element (IE) indicating one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
13. The UE of claim 12 , wherein a value of the IE is equal to an enumerated type true.
14. The UE of claim 10 , wherein the at least one processor is configured to cause the UE to determine that the busy indication functionality is supported when the information comprises parameters associated with the busy indication functionality.
15. The UE of claim 14 , wherein, to determine that the busy indication functionality is supported, the at least one processor is configured to cause the UE to determine one of:
the busy indication functionality for the CN paging is supported;
the busy indication functionality for the RAN paging is supported; or
the busy indication functionality for both the CN paging and the RAN paging is supported.
16. The UE of claim 10 , wherein the at least one processor is configured to cause the UE to determine whether to reject a paging message based on the busy indication functionality.
17. A base station for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the base station to:
transmit information related to busy indication functionality of a network, wherein the busy indication functionality is associated with at least one of core network (CN) paging or radio access network (RAN) paging, and wherein the information related to the busy indication functionality indicates whether the busy indication functionality is supported for at least one of the CN paging or the RAN paging; and
transmit a paging message based on the information.
18. The base station of claim 17 , wherein the at least one processor is configured to cause the base station to receive, from a CN entity, an indication of whether the busy indication functionality for CN paging is supported.
19. The base station of claim 18 , wherein the CN entity comprises at least one of an access and mobility management function (AMF) node or an operation administration and maintenance (OAM) node.
20. A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
receive information related to busy indication functionality of a network, wherein the busy indication functionality is associated with at least one of core network (CN) paging or radio access network (RAN) paging, and wherein the information related to the busy indication functionality indicates whether the busy indication functionality is supported for at least one of the CN paging or the RAN paging; and
determine that the busy indication functionality is supported based on the information.
