Method and system for discovering edge-server or edge-service through domain name server (DNS) resolution

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive signals;
• and
• a processor coupled with the transceiver,
• wherein the processor is configured to:
• transmit, to a domain name server (DNS) server, a DNS query including information on a web-based service of an application,
• as a response to the DNS query, receive, from the DNS server, a DNS response including server information on a plurality of servers associated with the web-based service, wherein the server information includes information on an internet protocol (IP) address and a server location, the information on the server location includes information of a latitude and a longitude for each of the plurality of servers, and information indicating whether a server is an edge server or not, and
• determine, by the terminal, an edge server or a remote server among the plurality of servers based on the information of the latitude and the longitude for each of the plurality of servers, and information indicating whether a server is an edge server or not.

A method performed by a domain name server (DNS) server in a wireless communication system, the method comprising:

• receiving, from a terminal, a DNS query including information on a web-based service of an application;
• generating server information including information on an internet protocol (IP) address and a server location, wherein the information on the server location includes information of a latitude and a longitude for each of a plurality of servers associated with the web-based service, and information indicating whether a server is an edge server or not;
• and
• as a response to the DNS query, transmitting, to the terminal, a DNS response including the server information used by the terminal to determine an edge server or a remote server from among the plurality of servers based on the information of the latitude and the longitude, and information indicating whether a server is an edge server or not.
