Control plane based configuration for time sensitive networking
A session management function (SMF) receives, from an access and mobility management function (AMF), a first request message. The first request message is for a time sensitive network (TSN) bridge. The SMF selects, based on the first request message, a user plane function (UPF) that supports TSN functionality. The SMF sends, to the UPF, a second request message to configure the UPF for the TSN bridge. The second request message comprises an identifier of the TSN bridge. The second request message comprises an identifier of a port associated with TSN packet transmission.
1. A method comprising:
receiving, by a session management function (SMF) from an access and mobility management function (AMF), a first request message indicating that the first request message is for a time sensitive network (TSN) bridge;
selecting, by the SMF, based on the first request message, a user plane function (UPF) that supports TSN functionality; and
sending, by the SMF to the UPF, a second request message to configure the UPF for the TSN bridge, the second request message comprising:
an identifier of the TSN bridge; and
an identifier of a port associated with TSN packet transmission.
2. The method of claim 1 , wherein the first request message is a request for establishment of a packet data unit (PDU) session.
3. The method of claim 1 , wherein the first request message comprises the identifier of the TSN bridge.
4. The method of claim 1 , wherein the first request message comprises the identifier of the port associated with TSN packet transmission.
5. The method of claim 1 , wherein the identifier of the port associated with TSN packet transmission comprises an identifier of a port of a wireless device for the TSN bridge.
6. The method of claim 1 , wherein the first request message comprises an identifier of a packet data unit (PDU) session.
7. The method of claim 1 , wherein the second request message comprises an identifier of a packet data unit (PDU) session.
8. The method of claim 1 , wherein the second request message is an N4 session establishment request message comprising an N4 session identifier.
9. The method of claim 1 , further comprising:
sending, by the SMF to a network repository function (NRF), a discovery request message to select the UPF; and
receiving, by the SMF from the NRF, an identifier of the UPF that supports TSN functionality.
10. The method of claim 9 , wherein the discovery request message comprises a TSN capability indicator.
11. A session management function (SMF) comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the session management function to:
receive, from an access and mobility management function (AMF), a first request message indicating that the first request message is for a time sensitive network (TSN) bridge;
select, based on the first request message, a user plane function (UPF) that supports TSN functionality; and
send, to the UPF, a second request message to configure the UPF for the TSN bridge, the second request message comprising:
an identifier of the TSN bridge; and
an identifier of a port associated with TSN packet transmission.
12. The SMF of claim 11 , wherein the first request message is a request for establishment of a packet data unit (PDU) session.
13. The SMF of claim 11 , wherein the first request message comprises the identifier of the TSN bridge.
14. The SMF of claim 11 , wherein the first request message comprises the identifier of the port associated with TSN packet transmission.
15. The SMF of claim 11 , wherein the identifier of the port associated with TSN packet transmission comprises an identifier of a port of a wireless device for the TSN bridge.
16. The SMF of claim 11 , wherein the first request message comprises an identifier of a packet data unit (PDU) session.
17. The SMF of claim 11 , wherein the second request message comprises an identifier of a packet data unit (PDU) session.
18. The SMF of claim 11 , wherein the second request message is an N4 session establishment request message comprising an N4 session identifier.
19. The SMF of claim 11 , further comprising:
sending, by the SMF to a network repository function (NRF), a discovery request message to select the UPF; and
receiving, by the SMF from the NRF, an identifier of the UPF that supports TSN functionality.
20. A system, comprising:
a session management function (SMF) comprising: one or more processors and memory storing instructions that, when executed by the one or more processors, cause the SMF to:
receive, from an access and mobility management function (AMF), a first request message indicating that the first request message is for a time sensitive network (TSN) bridge;
select, based on the first request message, a user plane function (UPF) that supports TSN functionality; and
send, to the UPF, a second request message to configure the UPF for the TSN bridge, the second request message comprising:
an identifier of the TSN bridge; and
an identifier of a port associated with TSN packet transmission; and
the UPF, wherein the UPF comprises: one or more processors and memory storing instructions that, when executed by the one or more processors, cause the UPF to receive the second request message.
