Parameter of time sensitive network bridge
A policy and charging control function (PCF) receives, from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge. The PCF sends, to the SMF, a response to the request, the response comprising the policy information of the wireless device.
1. A method comprising:
receiving, by a policy and charging control function (PCF) from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge; and
sending, by the PCF to the SMF, a response to the request, the response comprising the policy information of the wireless device.
2. The method of claim 1 , wherein the TSN bridge is between the wireless device and a network node.
3. The method of claim 1 , wherein the policy information comprises one or more user equipment route selection policy (URSP) rules.
4. The method of claim 3 , wherein the one or more URSP rules are for the TSN bridge.
5. The method of claim 4 , wherein the one or more URSP rules comprise at least one of:
a traffic descriptor of a TSN system comprising at least one of:
an identifier of the TSN bridge;
an identifier of a traffic descriptor of the TSN system; or
a priority value of the traffic descriptor of the TSN system; or
a TSN connection capability.
6. The method of claim 1 , wherein parameter of the TSN bridge further comprises one or more of:
a number of ports on the wireless device;
a parameter indicating that the wireless device supports spanning tree protocol; and
a parameter indicating that the wireless device supports TSN bridge functions.
7. The method of claim 1 , wherein the PCF makes policy decisions based on the parameter of the TSN bridge, the method further comprising subscribing, by the SMF, to changes in the policy decisions from the PCF.
8. The method of claim 1 , wherein the SMF sends, to the wireless device, the policy information for the wireless device in a configuration update message.
9. A policy and charging control function (PCF) comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the PCF to perform operations comprising:
receiving, from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge; and
sending, to the SMF, a response to the request, the response comprising the policy information of the wireless device.
10. The PCF of claim 9 , wherein the policy information comprises one or more user equipment route selection policy (URSP) rules.
11. The PCF of claim 10 , wherein the one or more URSP rules are for the TSN bridge.
12. The PCF of claim 11 , wherein the one or more URSP rules comprise:
a traffic descriptor of a TSN system comprising:
an identifier of a TSN bridge;
an identifier of a traffic descriptor of the TSN system; and
a priority value of the traffic descriptor of the TSN system; and
a TSN connection capability.
13. The PCF of claim 9 , wherein the parameter of the TSN bridge further comprises one or more of:
a number of ports on the wireless device;
a parameter indicating that the wireless device supports spanning tree protocol; and
a parameter indicating that the wireless device supports TSN bridge functions.
14. The PCF of claim 9 , wherein the PCF makes policy decisions based on the parameter of the TSN bridge.
15. The PCF of claim 9 , wherein the SMF sends, to the wireless device, the policy information for the wireless device in a configuration update message.
16. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a policy and charging control function (PCF) to perform operations comprising:
receiving, from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge; and
sending, to the SMF, a response to the request, the response comprising the policy information of the wireless device.
17. The non-transitory computer-readable medium of claim 16 , wherein the TSN bridge is between the wireless device and a network node.
18. The non-transitory computer-readable medium of claim 16 , wherein the policy information comprises one or more user equipment route selection policy (URSP) rules.
19. The non-transitory computer-readable medium of claim 18 , wherein the one or more URSP rules are for the TSN bridge.
20. The non-transitory computer-readable medium of claim 19 , wherein the one or more URSP rules comprise at least one of:
a traffic descriptor of a TSN system comprising at least one of:
an identifier of the TSN bridge;
an identifier of a traffic descriptor of the TSN system; or
a priority value of the traffic descriptor of the TSN system; or
a TSN connection capability.
