Method and apparatus for communication between application client (ac) and edge enabler client (eec) in a wireless communication system

A method performed by an edge enabler client (EEC) in a wireless communication system, the method comprising:

• transmitting, to an application client (AC), an EEC service notification message for triggering a domain name system (DNS) query based on an unavailability of target edge enabler server (T-EES) or a target edge application server (T-EAS);
• receiving, from the AC, a DNS trigger status report message;
• and
• transmitting, to the AC, a DNS trigger status report acknowledge message.

An application client (AC) in a wireless communication system, the AC comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from an edge enabler client (EEC), an EEC service notification message for triggering a domain name system (DNS) query based on an unavailability of target edge enabler server (T-EES) or a target edge application server (T-EAS);
• transmit, to the EEC, a DNS trigger status report message;
• and
• receive, from the EEC, a DNS trigger status report acknowledge message.
