Abstract

Claims (46)

1. A method to serve a user application in a User Equipment (UE), the method comprising:

receiving a subscription from an application server into a Network Exposure Function (NEF), wherein the subscription is for user data from the user application in the UE;

receiving the user data from the user application in the UE over a Virtual Private Network (VPN) and transferring the user data to the NEF; and

transferring the user data from the NEF for delivery to the application server in response to the subscription.

2. The method of claim 1 further comprising:

generating usage data that characterizes the user data transfer by UE identifier; and

transferring the UE identifier from the NEF for delivery to the application server in response to the subscription.

3. The method of claim 1 further comprising:

generating usage data that characterizes the user data transfer by UE location; and

transferring the UE location from the NEF for delivery to the application server in response to the subscription.

4. The method of claim 1 further comprising:

generating usage data that characterizes the user data transfer by application identifier; and

transferring the application identifier from the NEF for delivery to the application server in response to the subscription.

5. The method of claim 1 further comprising:

generating usage data that characterizes the user data transfer by VPN information; and

transferring the VPN information from the NEF for delivery to the application server in response to the subscription.

6. The method of claim 1 further comprising:

generating usage data that characterizes the user data transfer by data amount; and

transferring the data amount from the NEF for delivery to the application server in response to the subscription.

7. The method of claim 1 further comprising:

receiving an application instruction for the user application into the NEF from the application server; and

transferring the application instruction for the user application from the NEF to the UE over the VPN.

8. A method to serve a user application in a User Equipment (UE), the method comprising:

a Network Exposure Function (NEF) receiving a usage data subscription for the UE;

the NEF receiving UE signaling from the UE over a Virtual Private Network (VPN) and transferring the UE signaling to a network function;

the network function receiving the UE signaling from the NEF, and in response, transferring network signaling to the NEF;

the NEF receiving the network signaling from the network function and transferring the network signaling to the VPN;

the VPN exchanging data for the user application between the UE and an external data system based on the network signaling; and

the NEF transferring usage data that characterizes the data exchange to the application server in response to the usage data subscription.

9. The method of claim 8 wherein the UE signaling comprises a Non-Access Stratum (NAS) file from the UE.

10. The method of claim 8 wherein the UE signaling indicates the user application in the UE.

11. The method of claim 8 wherein the network signaling indicates a VPN policy for the UE.

12. The method of claim 8 wherein the usage data identifies the user application and the external data system.

13. The method of claim 8 further comprising the NEF transferring the usage data to a network accounting system.

14. A data communication network to serve a user application in User Equipment (UE), the data communication network comprising:

a Network Function Virtualization Infrastructure (NFVI) to execute a Network Exposure Function (NEF), the NEF to receive a subscription from an application server, wherein the subscription is for user data from the user application in the UE;

a Virtual Private Network (VPN) to receive the user data from the user application in the UE and transfer the user data to the NEF; and

the NEF to transfer the user data for delivery to the application server in response to the subscription.

15. The data communication network of claim 14 further comprising the NEF to transfer usage data for delivery to the application server in response to the subscription, wherein the usage data characterizes the user data transfer by UE identifier.

16. The data communication network of claim 14 further comprising the NEF to transfer usage data for delivery to the application server in response to the subscription, wherein the usage data characterizes the user data transfer by UE location.

17. The data communication network of claim 14 further comprising the NEF to transfer usage data for delivery to the application server in response to the subscription, wherein the usage data characterizes the user data transfer by application identifier.

18. The data communication network of claim 14 further comprising the NEF to transfer usage data for delivery to the application server in response to the subscription, wherein the usage data characterizes the user data by VPN information.

19. The data communication network of claim 14 further comprising the NEF to transfer usage data for delivery to the application server in response to the subscription, wherein the usage data characterizes the user data by data amount.

20. The data communication network of claim 14 further comprising:

the NEF to receive an application instruction for the user application in the UE from the application server and transfer the application instruction to the VPN; and

the VPN to transfer the application instruction to the user application in the UE.
