Certificate based application descriptors for network slice selection
Various aspects of the present disclosure generally relate to certificate based application descriptors for network slice selection. In some aspects, a user equipment (UE) may receive a first certificate associated with obtaining a network slice for executing an application. The UE may transmit, to a device, a request for the network slice with the first certificate, and receive an indication that the network slice is available to the UE for the application, based at least in part on the request. Numerous other aspects are provided.
1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a first slice certificate associated with obtaining a network slice for executing an application;
transmitting, to a device, a request for the network slice with the first slice certificate; and
receiving an indication that the network slice is available to the UE for the application, based at least in part on the request, wherein the UE uses a token to securely map the application to the network slice.
2. The method of claim 1 , wherein the device is one or more of a mobile network operator, an access and mobility management function, or a policy and control function.
3. The method of claim 1 , wherein the first slice certificate is received from an application service provider that has secret data of the application, wherein the application has permission from the device to use the network slice.
4. The method of claim 3 , wherein the application has the secret data and receives the first slice certificate.
5. The method of claim 3 , wherein the request includes a timestamp and a signature generated by encrypting the secret data and the timestamp with a private key for the first slice certificate.
6. The method of claim 5 , further comprising generating the signature by encrypting the secret data and the timestamp with a public key for the first slice certificate.
7. The method of claim 1 , further comprising establishing a protocol data unit session based at least in part on the first slice certificate.
8. The method of claim 1 , further comprising determining whether to transmit the request for the network slice based at least in part on statistics associated with the application.
9. The method of claim 1 , wherein securely mapping the application to the network slice comprises securely mapping the application to the network slice using a modem of the UE.
10. The method of claim 1 , further comprising notifying, by a modem of the UE, the application of the network slice.
11. The method of claim 1 , wherein the first slice certificate is received from the device, and the device is an access and mobility management function entity.
12. The method of claim 11 , wherein the application receives the first slice certificate from an application service provider and provides the first slice certificate to a modem of the UE in association with the request for the network slice, and wherein the method further comprises validating, at the modem of the UE, the first slice certificate from the application on the UE with the first slice certificate received from the device.
13. The method of claim 11 , wherein the application receives the first slice certificate from an application service provider and provides the first slice certificate to a modem of the UE in association with the request for the network slice, and wherein the method further comprises validating, at the modem of the UE, a signature from the application on the UE with a signature in a UE route selection policy.
14. A method performed by a device, comprising:
receiving, from a user equipment (UE), a request for a network slice for executing an application, wherein the request includes a first slice certificate associated with obtaining the network slice;
transmitting the first slice certificate to an application service provider for validation; and
transmitting an indication to the UE that the network slice is available to the UE based at least in part on the validation, wherein the application is securely mapped to the network slice using a token.
15. The method of claim 14 , wherein the device is one or more of a mobile network operator, an access and mobility management function, or a policy and control function.
16. The method of claim 14 , further comprising determining the network slice based at least in part on the validation.
17. A method performed by an application service provider, comprising:
transmitting, to a user equipment (UE), a first slice certificate associated with the UE obtaining a network slice for executing an application;
receiving, from a device, the first slice certificate and a request for a second slice certificate of the device associated with the application; and
transmitting the second slice certificate to the device based at least in part on a determination that the first slice certificate is valid, wherein the application is securely mapped to the network slice using a token.
18. The method of claim 17 , further comprising establishing the second slice certificate with the device.
19. The method of claim 17 , wherein the device is one or more of a mobile network operator, an access and mobility management function, or a policy and control function.
20. A method performed by a device, comprising:
generating a first slice certificate associated with a user equipment (UE) obtaining a network slice;
transmitting the first slice certificate to an application service provider;
providing a private key for the first slice certificate to the UE; and
transmitting an indication, to the UE with the first slice certificate, that the network slice is available to the UE for an application, wherein the application is securely mapped to the network slice using a token.
21. The method of claim 20 , wherein the device is one or more of a mobile network operator, an access and mobility management function, or a policy and control function.
22. The method of claim 20 , further comprising updating a UE route selection policy.
23. A method performed by an application service provider, comprising:
receiving, from a device, a first slice certificate associated with a user equipment (UE) obtaining a network slice for executing an application; and
transmitting the first slice certificate to the application at the UE, wherein the application is securely mapped to the network slice using a token.
24. The method of claim 23 , wherein the device is one or more of a mobile network operator, an access and mobility management function, or a policy and control function.
25. The method of claim 23 , further comprising generating a signature for the network slice.
