Claims

1. A network device (100) configured to:

- obtain a control information (101) based on an exposure information (102); and

- trigger an adaptation of a network and/or management function based on the control information (101).

2. The network device (100) according to claim 1, wherein the exposure information (102) is obtained from another device and/or is predetermined.

3. The network device (100) according to claim 1 or 2, wherein the adaptation of the network and/or management function comprises an adaptation of a billing and/or charging function (201).

4. The network device (100) according to any one of the preceding claims, wherein the exposure information (102) comprises an information related to a vehicle to anything, V2X, service and/or a V2X service mode and in particular a mapping of this information to an exposed capability of a network function, NF.

5. The network device (100) according to any one of the preceding claims, wherein the exposure information (102) further comprises at least one of the following parameters:

- Service ID

- NSSAI

- LCU ID

- Exposure level of an NF to be exposed

- Time validity and/or periodicity

- Geographical Area, e.g. a RSU-level, a cell-level, or a TA level.

6. The network device (100) according to any one of the preceding claims, wherein the control information (101) comprises an exposure of a NF to an application function, AF.

7. The network device (100) according any of the preceding claims, wherein the control information (101) comprises a control traffic report from the NF.

8. The network device (100) according to claim 7, wherein the control traffic report comprises at least one of the following parameters:

- Service ID

- Device ID

- User ID / or Group-UE IDs and/or PDU Session ID(s)

- Exposed Control traffic parameters:

- Volume

- Criticality,

- Time validity and/or periodicity

- Geographical Area, e.g. RSU-level, cell-level, TA level.

9. The network device (100) according to any one of the preceding claims, configured to obtain the control information (101) per PDU session and/or per traffic flow.

10. The network device (100) according to any one of the preceding claims, configured to adapt the network and/or management function based on an exposure demand information, in particular based on the control information (101), and wherein the exposure demand information includes at least one of the following parameters:

- Service ID,

- NSSAI,

- Exposed Control traffic parameters per vertical customer:

- Billing estimation,

- Volume,

- Criticality,

- Time validity and/or periodicity,

- Geographical Area, e.g. RSU-level, cell-level, TA level.

11. The network device (100) according to any one of the preceding claims, further configured to adapt the network and/or management function based on an adaptation of a vehicle-to-vehicle, V2V, communication mode.

12. The network device (100) according to any one of the preceding claims, further configured to adapt the obtaining of the control information (101) based on an application request and/or based on a network request.

13. The network device (100) according to any one of the preceding claims, further configured to adapt the obtaining of the control information (101) based on a change of a V2V session.

14. The network device (100) according to claim 13, wherein the a change of the V2V session is a change of a level of automation, LoA, in particular caused by a V2X server.

15. The network device (100) according to any one of the preceding claims, further configured to adapt the obtaining of the control information (101) based on a change of network slice instances, NSIs, associated with a V2V session (501).

16. The network device (100) according to any one of the preceding claims, wherein the network device (100) is further configured to trigger the adaptation of the network and/or management function periodically or upon request.

17. A method (600) for operating a network device (100), the method comprising the steps of:

- obtaining (601), by the network device (100), a control information (101) based on an exposure information (102); and

- triggering (602), by the network device (100), an adaptation of a network and/or management function based on the control information (101).
