Method and apparatus for providing data in edge computing system

1. An application context relocation method performed by an edge enabler client (EEC) included in a user equipment (UE) in an edge computing system, the application context relocation method comprising:

determining to request an application context relocation by detecting, by the EEC, that the application context relocation is required for a predicted or expected UE location;

determining a target edge enabler server (T-EES) by using T-EES information received from an edge data network (EDN) configuration server;

transmitting, to a source edge enabler server (S-EES), an application context relocation request to start the application context relocation;

receiving, from the S-EES, an application context relocation response, in response to the application context relocation request; and

receiving, from the S-EES, an application context relocation notification of completion of the application context relocation.

2. The application context relocation method of claim 1 , wherein the predicted or expected UE location indicates at least one of a cell or a tracking area identifying a network to which the UE is connected.

3. The application context relocation method of claim 1 , wherein the T-EES information includes a uniform resource identifier (URI) for connecting to the T-EES.

4. The application context relocation method of claim 1 , further comprising rerouting application data to a target edge application server (T-EAS), based on the application context relocation response.

5. The application context relocation method of claim 1 , wherein the application context relocation request includes a UE identifier (ID) and a fully qualified domain name (FQDN) of a source edge application server (S-EAS).

6. A user equipment (UE) for use in an edge computing system, the UE comprising:

an application client (AC) configured to an edge computing service from an edge application server (EAS);

a mobile terminal (MT) configured to communicate with a mobile communication network and connect an edge data network (EDN) through the mobile communication network; and

an edge enabler client (EEC) configured to:

determine that an application context relocation should be requested by detecting that the application context relocation is required for a predicted or expected UE location,

determine a target edge enabler server (T-EES) by using T-EES information received from an EDN configuration server,

transmit, to a source EES (S-EES), an application context relocation request to start the application context relocation,

receive, from the S-EES, an application context relocation response, in response to the application context relocation request, and

receive, from the S-EES, an application context relocation notification of completion of the application context relocation.

7. The UE of claim 6 , wherein the predicted or expected UE location indicates at least one of a cell or a tracking area identifying a network to which the UE is connected.

8. The UE of claim 6 , wherein the T-EES information includes a uniform resource identifier (URI) for connecting to the T-EES.

9. The UE of claim 6 , wherein the EEC is further configured to reroute application data to a target EAS (T-EAS), based on the application context relocation response.

10. The UE of claim 6 , wherein the application context relocation request includes a UE identifier (ID) and a fully qualified domain name (FQDN) of a source EAS (S-EAS).

11. An application context relocation method performed by a source edge enabler server (S-EES) in an edge computing system, the application context relocation method comprising:

receiving, from an edge enabler client (EEC), an application context relocation request to start an application context relocation;

notifying, to an source edge application server (S-EAS), that the application context relocation is required;

transmitting, to the EEC, an application context relocation response, in response to the application context relocation request;

receiving, from the S-EAS, a notification that the application context relocation is complete; and

transmitting, to the EEC, an application context relocation notification that the application context relocation is complete.

12. The application context relocation method of claim 11 , wherein the application context relocation request includes a UE identifier (ID) and a fully qualified domain name (FQDN) of the S-EAS.

13. The application context relocation method of claim 11 , further comprising:

transmitting an application context relocation command including the T-EAS information to the S-EAS providing an application service to the UE; and

transmitting an application context to the T-EAS through the T-EES when the application context is received from the S-EAS.
