Method and apparatus for providing service to edge application server (eas) in edge data network (EDN)
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Accordingly, embodiments herein disclose a method for providing service(s) to an edge application server (EAS) in an edge data network (EDN). The method includes receiving, by an EES, an EAS usage indication from an edge enabler client (EEC) of a user equipment (UE), where the EAS usage indication comprises at least one parameter.
1. A method performed by an edge enabler server (EES) in an edge data network (EDN), the method comprises:
receiving, from an edge enabler client (EEC) of a user equipment (UE), a message for an edge application server (EAS) usage indication, the message being associated with an application context relocation (ACR), wherein the message comprises an identifier (ID) of an EAS that is selected by the EEC, the selected EAS being one of at least one discovered EAS and used by an application client (AC) of the UE;
identifying the ID of the selected EAS; and
providing a service associated with the ACR to the selected EAS having the ID of the selected EAS.
2. The method of claim 1 , further comprising:
determining whether credentials of the EEC are valid; and
storing at least one parameter included in the message based on a determination that the credentials of the EEC are valid.
3. The method of claim 1 , wherein the message further comprises at least one of an ID of the EEC, security credentials of the EEC, or an ID of the UE.
4. The method of claim 1 ,
wherein the at least one discovered EAS is, by the EEC, discovered by using an edge configuration server (ECS) and the EES, and
wherein the AC of the UE establishes a connection with the selected EAS for the service.
5. The method of claim 1 , wherein the selected EAS is selected based on a support of an application client (AC) of the UE.
6. The method of claim 1 , further comprising:
sending a second message for an EAS usage indication acknowledgment to the EEC, wherein the second message comprises at least one of a successful response, an ID of the EES (EESID), security credentials of the EES, a failure response, or a cause of failure.
7. The method of claim 1 , wherein the message is an application context relocation (ACR) information subscription message, an EEC registration update message, or an EEC context message.
8. The method of claim 1 , wherein providing the service associated with the ACR to the selected EAS comprises at least one of:
reserving at least one resource, the at least one resource comprising at least one of a compute resource for the EAS or storage resource for the EAS;
monitoring a location of the UE to provide assistance to the EAS for the ACR; or
subscribing to information associated with the UE and utilizing 3 rd generation partnership project (3GPP) core network capability exposure application programming interfaces (APIs).
9. An edge enabler server (EES) in an edge data network (EDN), the EES comprising:
a memory;
a transceiver; and
a controller, operably connected to the memory and the transceiver, configured to:
receive, from an edge enabler client (EEC) of a user equipment (UE), a message for an edge application server (EAS) usage indication, the message being associated with an application context relocation (ACR), wherein the message comprises an identifier (ID) of an EAS that is selected by the EEC, the selected EAS being one of at least one discovered EAS and used by an application client (AC) of the UE,
identify the ID of the selected EAS, and
provide a service associated with the ACR to the selected EAS having the ID of the selected EAS.
10. The EES of claim 9 , wherein the controller is further configured to:
determine whether credentials of the EEC are valid; and
store at least one parameter included in the message based on a determination that the credentials of the EEC are valid.
11. The EES of claim 9 , wherein the message further comprises at least one of an ID of the EEC, security credentials of the EEC, or an ID of the UE.
12. The EES of claim 9 , wherein the controller is further configured to:
send a second message for an EAS usage indication acknowledgment to the EEC, the second message comprising at least one of a successful response, an ID of the EES (EESID), security credentials of the EES, a failure response, or a cause of failure.
13. The EES of claim 9 , wherein the message is an application context relocation (ACR) information subscription message, an EEC registration update message, or an EEC context message.
14. The EES of claim 9 , wherein providing the service associated with the ACR to the selected EAS comprises at least one of:
reserving at least one resource, the at least one resource comprising at least one of a compute resource for the EAS or storage resource for the EAS;
monitoring a location of the UE to provide assistance to the EAS for the ACR; or
subscribing to information associated with the UE and utilizing 3 rd generation partnership project (3GPP) core network capability exposure application programming interfaces (APIs).
