Systems and methods for time-sensitive networking analytics

1 . A method, comprising:

receiving, by a Network Data Analytics Function (NWDAF) in a core network, an information request for a Time Sensitive Networking (TSN) service;

sending, by the NWDAF and to a Time Sensitive Communication Time Synchronization Function (TSCTSF), a data request, based on the information request, to subscribe to receive TSN quality of service (QoS) statistics from the TSCTSF;

collecting, by the NWDAF and from the TSCTSF, event data responsive to the data request;

segregating, by the NWDAF, the collected event data in a separate analytics environment that is isolated from other network data received by the NWDAF; and

generating, by the NWDAF, an analytics report based on the collected event data, and at least one of:

wherein the information request identifies a TSN slice type, or

wherein the collected event data includes a port state of a Network Side TSN Translator (NW-TT).

2 . The method of claim 1 , further comprising:

sending, by the NWDAF, the analytics report to a network function via a standardized interface.

3 . The method of claim 1 , wherein receiving the information request includes receiving an NWDAF analytics request for one of a request-response model or a subscription-notification model.

4 . The method of claim 1 , wherein sending the data request includes sending the data request to the TSCTSF via a standardized interface.

5 . The method of claim 1 , wherein the segregating further comprises:

directing the collected event data into one of a secure enclave or a trusted execution environment.

6 . The method of claim 1 , wherein generating the analytics report includes:

generating the analytics report in an isolated TSN analytics environment of the NWDAF.

7 . The method of claim 1 , wherein the collected event data includes Generalized Precision Time Protocol ((g) PTP) functionalities of a Device Side TSN Translator (DS-TT) and a Network Side TSN Translator (NW-TT).

8 . A network device comprising:

a processor configured to:

receive, by a Network Data Analytics Function (NWDAF) in a core network, an information request for a Time Sensitive Networking (TSN) service;

send, to a Time Sensitive Communication Time Synchronization Function (TSCTSF), a data request, based on the information request, to subscribe to receive TSN quality of service (QoS) statistics from the TSCTSF;

collect, from the TSCTSF, event data responsive to the data request;

segregate the collected event data in a separate analytics environment that is isolated from other network data received by the NWDAF; and

generate an analytics report based on the collected event data, and at least on of:

wherein the information request identifies a TSN slice type, or

wherein the collected event data includes a port state of a Network Side TSN Translator (NW-TT).

9 . The network device of claim 8 , wherein the processor is further configured to:

send the analytics report to a network function via a standardized interface.

10 . The network device of claim 8 , wherein when receiving the information request, the processor is further configured to:

receive an NWDAF analytics request for one of a request-response model or a subscription-notification model.

11 . The network device of claim 8 , wherein when sending the data request, the processor is further configured to:

send the data request to the TSCTSF via a standardized interface.

12 . The network device of claim 8 , wherein, when segregating the event data, the processor is further configured to:

direct the collected event data into one of a secure enclave or a trusted execution environment.

13 . The network device of claim 12 , wherein, when generating the analytics report, the processor is further configured to:

generate the analytics report in an isolated TSN analytics environment of the NWDAF.

14 . The network device of claim 8 , wherein the collected event data includes clock parameters for a Device Side TSN Translator (DS-TT) and a Network Side TSN Translator (NW-TT).

15 . A non-transitory computer-readable medium containing instructions executable by at least one processor, the computer-readable medium comprising the instructions for:

receiving, by a Network Data Analytics Function (NWDAF) in a core network, an information request for a Time Sensitive Networking (TSN) service;

sending, by the NWDAF and to a Time Sensitive Communication Time Synchronization Function (TSCTSF), a data request, based on the information request, to subscribe to receive TSN quality of service (QoS) statistics from the TSCTSF;

collecting, by the NWDAF and from the TSCTSF, event data responsive to the data request;

segregating, by the NWDAF, the collected event data in a separate analytics environment that is isolated from other network data received by the NWDAF; and

generating, by the NWDAF, an analytics report based on the collected event data, and at least one of:

wherein the information request identifies a TSN slice type, or

wherein the collected event data includes a port state of a Network Side TSN Translator (NW-TT).

16 . The non-transitory computer-readable medium claim 15 , further comprising instructions for:

generating the analytics report in an isolated TSN analytics environment.

17 . The non-transitory computer-readable medium claim 15 , further comprising instructions for:

sending, by the NWDAF, the analytics report to a network function via a standardized interface.

18 . The non-transitory computer-readable medium claim 15 , wherein the collected event data includes clock parameters for a Device Side TSN Translator (DS-TT).

19 . The non-transitory computer-readable medium claim 15 , wherein the instructions for receiving the information request include instructions for:

receiving an NWDAF analytics request for a subscription-notification model.

20 . The non-transitory computer-readable medium claim 15 , wherein the instructions for segregating the event data include instructions for:

directing the collected event data into one of a secure enclave or a trusted execution environment.
