Quality of service (QoS) policy selection and flow creation based on domain name system (DNS) application metadata

A computing device comprising:

• one or more network interfaces to connect in a mobile network;
• one or more processors;
• one or more memory elements coupled to the one or more processors;
• the one or more memory elements for storing instructions executable on the one or more processors for operation as a user plane function including:
• receiving, from a user device, a domain name system (DNS) query for an application for the user device;
• sending, to a DNS server having a DNS as Authoritative Source (DNS-AS) mechanism, a first corresponding DNS query based on the DNS query;
• receiving, from the DNS server, a first DNS query response which includes the IP address;
• sending, to the DNS server, a second corresponding DNS query which indicates a request for metadata associated with the application;
• receiving, from the DNS server, a second DNS query response which includes the metadata associated with the application, the metadata including the application identifier associated with the application;
• and
• sending, to a control plane function, a message for reporting which includes the application identifier associated with the application,
• wherein, in response to the message for reporting, a dedicated Quality of Service (QoS) Flow is created for traffic for the application for the user device via the user plane function according to a selected QoS policy associated with the application identifier.

A method comprising:

• at a user plane function configured for use in a mobile network,
• receiving, from a user device, a domain name system (DNS) query for an application for the user device;
• sending, to a DNS server having a DNS as Authoritative Source (DNS-AS) mechanism, a first corresponding DNS query based on the DNS query;
• receiving, from the DNS server, a first DNS query response which includes the IP address;
• sending, to the DNS server, a second corresponding DNS query which indicates a request for metadata associated with the application;
• receiving, from the DNS server, a second DNS query response which includes the metadata associated with the application, the metadata including the application identifier associated with the application;
• and
• sending, to a control plane function, a message for reporting which includes the application identifier associated with the application,
• wherein, in response to the message for reporting, a dedicated Quality of Service (QoS) Flow is created for traffic for the application for the user device via the user plane function according to a selected QoS policy associated with the application identifier.
