Method for identification of traffic suitable for edge breakout and for traffic steering in a mobile network

A method executed in a domain name system (DNS) proxy for identification of traffic suitable for edge breakout and for traffic steering in a mobile network, comprising:

• receiving a DNS query from a user equipment (UE) with an application fully qualified domain name (FQDN);
• upon determining that edge computing is applicable to the DNS query, adding one or more internet protocol (IP) address, IP address range or IP subnet as one or more Extension mechanisms for DNS (EDNS) client subnet (ECS) option to the DNS query, corresponding to one or more preferred location for accessing to a data network (DN);
• forwarding the DNS query;
• receiving a DNS response;
• upon determining that the received DNS response includes an ECS option that corresponds to one of the one or more ECS option of the DNS query, to which the DNS response has been tailored, triggering actions to set up traffic steering according to the ECS option;
• and
• upon successful completion of the actions triggered to set up the traffic steering, removing the ECS option from the DNS response and sending the DNS response to the UE.

A domain name system (DNS) proxy for application server (AS) discovery for edge computing in a mobile network operative, the DNS proxy comprising processing circuitry configured to:

• receive a DNS query from a user equipment (UE) with an application fully qualified domain name (FQDN);
• upon determining that there is a service level agreement (SLA) in place for an application corresponding to the FQDN, obtain a location of the UE that sent the DNS query from a control plane;
• add at least one subnet or full IP address of one or more preferred location for accessing to a data network (DN) as one or more Extension mechanisms for DNS (EDNS) client subnet (ECS) options in the DNS query;
• forward the DNS query to a mobile network operator (MNO) DNS;
• receive a DNS response comprising an ECS option, the ECS option being tailored to a corresponding ECS option of the one or more ECS option in the DNS query;
• trigger actions to set up traffic steering according to the ECS option received in the DNS response;
• and
• remove the ECS option from the DNS response and sending the DNS response to the UE.
