Method and system for adjusting the UE (Union Engine) downtime parameter in a wireless network

Abstract

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. A method for adjusting an unavailable period parameter of a User Equipment (UE) in a wireless network is provided. The method includes an operation of determining an unavailable period parameter of the UE based on at least one event performed in the UE by an application function (AF) of a network device in the wireless network. Furthermore, the method includes an operation of sending, by the AF of the network device, the unavailable period parameter of the UE to an access and mobility management function (AMF) of the network device. Furthermore, the method includes an operation of configuring the unavailable period parameter in the UE. In one embodiment, the UE detects that an event must be performed, and the UE initiates a non-access stratum (NAS) procedure to indicate that it will become unavailable by indicating the unavailable period parameter to a fifth generation core (5GC), and the 5GC transfers the unavailable period parameter to the AF, thereby achieving coordination between the UE, the 5GC, and the AF.

Claims

1. A method performed by user equipment (UE) in a wireless network, An operation in which the UE identifies at least one event that causes it to become unavailable during the unavailable period; An operation to identify unavailable configuration information based on at least one event that causes the configuration to become unavailable; The operation of transmitting the aforementioned unavailable configuration information to the access and mobility management function (AMF); An operation to receive an instruction from the AMF regarding whether or not the UE is permitted to become unavailable; and A method including the action of performing the at least one event that becomes unavailable based on the instructions from the AMF.

2. The method according to claim 1, wherein the unavailable configuration information includes at least one of the start time of the unavailable period or the duration of the unavailable period.

3. The method according to claim 1, wherein the unavailable configuration information is included in a registration request message or a deregistration request message transmitted from the AMF.

4. The method according to claim 1, wherein the unavailability period begins after the start time indicated by the unavailability configuration information, or after the moment the UE transmits the unavailability configuration information to the AMF.

5. The method according to claim 1, wherein an instruction on whether the UE is allowed to become unavailable is received via a registration acceptance message or a registration cancellation acceptance message.

6. A method performed by an access and mobility management function (AMF) in a wireless network, The operation of receiving unavailable configuration information from user equipment (UE); An operation to determine, based on the received unavailability configuration information, whether the UE is permitted to become unavailable during the unavailability period; An action to send an instruction to the UE indicating whether or not it is permitted for the UE to become unavailable; and A method including the action of notifying the application function (AF) of the UE which has been authorized to become unavailable.

7. The method according to claim 6, wherein the UE that becomes unavailable cannot reach the paging (page) from the wireless network.

8. The method according to claim 6, wherein the unavailable configuration information includes at least one of the start time of the unavailable period or the duration of the unavailable period.

9. The method according to claim 6, wherein the unavailable configuration information is included in a registration request message or a deregistration request message received from the UE.

10. The method according to claim 6, wherein the unavailability period begins after the start time indicated by the unavailability configuration information, or after the moment the unavailability configuration information is received.

11. The method according to claim 6, wherein an instruction on whether the UE is permitted to become unavailable is transmitted via a registration acceptance message or a registration cancellation acceptance message.

12. The method according to claim 6, wherein an event notification report to be sent to the AF for a UE that is permitted to become unavailable is transmitted to the AF via a policy control function (PCF), unified data management (UDM), or network exposure function (NEF).

13. A user equipment (UE) device in a wireless network, Memory; The memory includes a processor functionally connected to the memory, the processor being: The aforementioned UE identifies at least one event that causes it to become unavailable during the unavailability period. Based on the at least one event that causes the system to become unavailable, the system identifies the unavailable configuration information. The aforementioned unavailable configuration information is transmitted to the access and mobility management function (AMF). The AMF receives an indication of whether the UE is allowed to become unavailable. A device configured to perform at least one event that becomes unavailable based on the instructions from the AMF.

14. The apparatus according to claim 13, wherein the unavailable configuration information includes at least one of the start time of the unavailable period or the duration of the unavailable period.

15. An access and mobility management function (AMF) device for a wireless network, Memory; Includes a processor functionally connected to memory, wherein the processor: Unavailability configuration information is received from user equipment (UE). Based on the received unavailable configuration information, it is determined whether the UE is permitted to become unavailable during the unavailability period. Send an instruction to the UE indicating whether it is permitted for the UE to become unavailable. A device configured to notify the application function (AF) of the UE that is authorized to become unavailable.
