receiving a first subscription message from the H-PCF; and

transmitting a second subscription message to a V-UDR (Visited Public Land Mobile Network-Unified Data Repository),

wherein the first subscription message is request for notification based EAS (edge application server) information being updated or modified,

wherein the second subscription message is request for notification based the EAS information being updated or modified,

wherein the second subscription message is based on the first subscription message,

wherein the EAS information created by AF (Application Function) is transmitted to the V-UDR.

2. The method of claim 1 ,

wherein the EAS information includes IP address of EAS and FQDN (Fully Qualified Domain Name) of the EAS.

3. The method of claim 1 ,

wherein the EAS information is related to service identified by one among i) combination of DNN (Data Network Name) and S-NSSAI (Single Network Slice Selection Assistance Information), ii) AF-Service-Identifier and iii) application identifier.

6. A method for performing communication with Edge computing, performed by an H-PCF (Home Public Land Mobile Network-Policy Control Function), comprising:

establishing UE Policy Association with a V-PCF (Visited Public Land Mobile Network-Policy Control Function);

transmitting a first subscription message to the V-PCF,

wherein the first subscription message is request for notification based EAS (edge application server) information being updated or modified,

wherein the first subscription message makes the V-PCF transmit a second subscription message to V-UDR (Visited Public Land Mobile Network-Unified Data Repository),

wherein the second subscription message is request for notification based the EAS information being updated or modified,

wherein the EAS information created by AF (Application Function) is transmitted to the V-UDR;

receiving, from the V-PCF, a notification message indicating that the EAS information was updated or modified;

determining URSP (UE Route Selection Policy) rules, based on the notification message;

transmitting the URSP rules to a UE (user equipment) via the V-PCF.

7. The method of claim 6 ,

wherein the EAS information includes IP address of EAS and FQDN (Fully Qualified Domain Name) of the EAS.

8. The method of claim 6 ,

wherein the EAS information is related to service identified by one among i) combination of DNN (Data Network Name) and S-NSSAI (Single Network Slice Selection Assistance Information), ii) AF-Service-Identifier and iii) application identifier.
