US 12,184,606 B2 · Method and device for edge application server discovery

Abstract

The disclosure relates to a 5th generation (5G) communication system communication scheme and a system thereof to support a higher data rate than that of the 4th generation (4G) system. A method performed by an edge application server discover function (EASDF) to discover an edge application server (EAS) is provided. The method includes, receiving a context message including a DNS message processing rule from an session management function (SMF), receiving a DNS query message from a user equipment (UE), transmitting the processed DNS query message to a DNS server based on the DNS message processing rule, receiving a DNS response message including an EAS internet protocol (IP) address from the DNS server, and transmitting the DNS response message to the UE based on the DNS message processing rule.

Dependent claims

A method performed by a session management function (SMF), the method comprising:

obtaining edge application server (EAS) configuration information provided from an application function (AF);
generating a domain name system (DNS) message processing rule based on the EAS configuration information;
and
transmitting, to an edge application server discover function (EASDF) entity, a context message comprising the generated DNS message processing rule,
wherein the EAS configuration information comprises at least one of:
one or more fully qualified domain name (FQDN),
one or more data network access identifiers (DNAIs) for the EAS configuration information, or
one or more DNS server information for each DNAI,
wherein the DNS message processing rule comprises:
an identifier of the DNS message processing rule,
an EAS IP address range related to a DNS response message, and
a reporting-once indication of a DNS message corresponding to the EAS IP address range.
