Abstract

The present disclosure relates to Edge Computing enhancements by provisioning applications with mobile network provided Domain Name System (DNS) settings. In one embodiment, a method performed by a User Equipment (UE), which supports an Edge Application Server (EAS) discovery procedure with an Edge Application Server Discovery Function (EASDF), includes receiving a DNS setting provided by a mobile network, and storing a first copy of the DNS setting provided by the mobile network as a first DNS setting and a second copy of the DNS setting provided by the mobile network. Herein, the stored first DNS setting is not impacted by any changes made to the second copy of the DNS setting provided by the mobile network.

First claim

The invention claimed is:

1. A method performed by a User Equipment, UE, which supports an Edge Application Server, EAS, discovery procedure, the method comprising:
at an Operating System, OS, of the UE, the OS having a first Domain Name System, DNS, setting provided by a mobile network and a second DNS setting that is a user defined preference for DNS resolution:
receiving a request for the first DNS setting from an application client of an application via an Application Programming Interface, API, of the OS;
obtaining the first DNS setting; and
sending the first DNS setting to the application client via the API, responsive to the request; and

at the application of the UE, for EAS discovery:
sending the request for the first DNS setting from the application client of the application to the OS via the API of the OS; and
receiving the first DNS setting from the OS via the API of the OS; and
resolving a Fully Qualified Domain Name, FQDN, of the application using the first DNS setting.

2. The method of claim 1 , further comprising storing the first DNS setting provided by the mobile network and a second copy of the first DNS setting provided by the mobile network.

3. The method of claim 2 , further comprising overwriting the second copy of the first DNS setting provided by the mobile network with the second DNS setting and storing the second DNS setting.

4. The method of claim 2 , wherein the first DNS setting provided by the mobile network is not impacted by any changes made to the second copy of the first DNS setting provided by the mobile network.

5. The method of claim 1 , wherein the second DNS setting is different from the first DNS setting.

6. The method of claim 1 , further comprising, at an OS DNS client of the OS, performing DNS resolving using the second DNS setting.

7. The method of claim 1 , wherein the first DNS setting provided by the mobile network is not impacted by any changes made to the second DNS setting.

8. A method performed by an application of a User Equipment, UE, the UE supporting an Edge Application Server, EAS, discovery procedure, the method comprising:
sending a request for a first Domain Name System, DNS, setting from an application client of the application to an Operating System, OS, via an Application Programming Interface, API, of the OS, wherein the first DNS setting is provided by a mobile network and is different than a second DNS setting stored by the OS that is a user defined preference for DNS resolution;
receiving the first DNS setting from the OS via the API of the OS, responsive to the request; and
resolving a Fully Qualified Domain Name, FQDN, of the application using the first DNS setting for EAS discovery.

9. The method of claim 8 , wherein the FQDN of the application is resolved by an application DNS client in the application client using the first DNS setting.

10. A User Equipment, UE, which supports an Edge Application Server, EAS, discovery procedure, comprising:
one or more transmitters;
one or more receivers; and
processing circuitry associated with the one or more transmitters and the one or more receivers, wherein:
the processing circuitry is configured to cause an application client of an application to send a request for a first Domain Name System, DNS, setting to an Operating System, OS, via an Application Programming Interface, API, to resolve a Fully Qualified Domain Name, FQDN, of the application for EAS discovery, wherein the OS has the first DNS setting is a first copy of a DNS setting provided by a mobile network and a second DNS setting that is a user defined preference for DNS resolution;
the processing circuitry is configured to cause the OS to obtain the first DNS setting; and
the processing circuitry is configured to cause the OS to send the first DNS setting to the application client via the API, responsive to the request.

11. The UE of claim 10 , wherein the processing circuitry is further configured to cause the OS to store the first DNS setting provided by the mobile network and a second copy of the first DNS setting provided by the mobile network.

12. The UE of claim 11 , wherein the processing circuitry is further configured to cause the OS to overwrite the second copy of the first DNS setting provided by the mobile network with the second DNS setting and store the second DNS setting.

13. The UE of claim 11 , wherein the first DNS setting, which is provided by the mobile network and stored by the OS, is not impacted by any changes made to the second copy of the first DNS setting provided by the mobile network.

14. The UE of claim 10 , wherein the second DNS setting is different from the first DNS setting.

15. The UE of claim 10 , wherein:
the OS further includes an OS Domain Name System, DNS, client; and
the processing circuitry is further configured to cause the OS DNS client to perform DNS resolving using the second DNS setting.

16. The UE of claim 10 , wherein the first DNS setting, which is provided by the mobile network and stored by the OS, is not impacted by any changes made to the second DNS setting.

17. The UE of claim 10 , wherein:
the application client includes an Application Domain Name System, DNS, client; and
the processing circuitry is further configured to cause the application DNS client to resolve the FQDN of the application using the first DNS setting.

18. The UE of claim 10 , wherein the processing circuitry is further configured to cause a modem for Third Generation Partnership Project, 3GPP, to utilize the first DNS setting or the second DNS setting to transmit signals.
