Method and apparatus for interaction between an edge computing system and a mobile communication network for providing edge computing service

A method performed by an edge application server (EAS) in a mobile communication network, the method comprising:

• transmitting, to an edge enabler server (EES), an event subscribe request message for user plane path change of a user equipment (UE);
• and
• receiving, from the EES in response to the event subscribe request message, a subscribe response message,
• wherein the event subscribe request message includes at least one of a subscription type or an indication of EAS acknowledgement, and
• wherein the subscription type indicates at least one of an early notification or a late notification.

An edge enabler server (EES) in a mobile communication network, the EES comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from an edge application server (EAS), an event subscribe request message for user plane path change of a user equipment (UE),
• check an existence of a subscription with 3rd generation partnership project (3GPP) core network for a user plane path change event notification of the UE,
• perform the subscription with the 3GPP core network for a user plane path event notification of the UE, in case that the subscription with 3GPP core network does not exist, and
• transmit, to the EAS, a subscribe response message,
• wherein the event subscribe request message includes at least one of a subscription type or an indication of EAS acknowledgement, and
• wherein the subscription type indicates at least one of an early notification or a late notification.
