Method to support 5G time sensitive communications
In some example embodiments, there may be provided a method that includes generating, by an application function and based on a time sensitive communication requirement for one or more end stations, at least one quality of service parameter for a time sensitive communication path from a talker end station through at least a portion of a 5G system to a listener end station; and sending, by the application function, a request towards a policy control function, the request including the at least one quality of service parameter configured to enable a creation, at the one or more 5G nodes, of a quality of service flow in accordance with the at least one quality of service parameter, wherein the one or more 5G nodes comprise a user plane function and/or at least one base station. Related systems, methods, and articles of manufacture are also disclosed.
1 . A method comprising:
receiving, at an end station including a user equipment or at a 5G node, a message from a session management function, the message including at least one quality of service parameter indicative of a scheduled gate timing for transmission and/or reception on a time sensitive communication, wherein the time sensitive communication is from a talker end station including the user equipment or the 5G node of a 5G system to a listener end station, without an external time sensitive network; and
transmitting, at the end station including the user equipment or the 5 G node, one or more packets in accordance with a quality of service using the at least one quality of service parameter indicative of the scheduled gate timing for transmission and/or reception.
2 . The method of claim 1 , wherein the 5G node comprises a base station and/or a user plane function.
3 . The method of claim 1 , further comprising creating a quality of service flow in accordance with the at least one quality of service parameter indicative of the scheduled gate timing for transmission and/or reception at the 5G node on the time sensitive communication.
4 . The method of claim 1 , wherein the end station including the user equipment directly couples to a user plane function via an N6 interface, and/or wherein the 5G node comprises a gNB.
5 . The method of claim 1 , wherein the at least one quality of service parameter indicative of the scheduled gate timing is determined based on a transport delay between the talker end station and the listener end station, and/or wherein the end station including the user equipment comprises the talker end station.
6 . The method of claim 1 , wherein the scheduled gate timing comprises a clock time.
7 . The method of claim 1 , wherein the scheduled gate timing represents an offset from a time known to the user equipment, a radio access node, an N3 bridge, and/or a user plane function.
8 . An apparatus comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
receive, from a session management function, a message including at least one quality of service parameter indicative of a scheduled gate timing for transmission and/or reception on a time sensitive communication, wherein the time sensitive communication is from a talker end station including the apparatus to a listener end station, without an external time sensitive network, wherein the apparatus comprises or is comprised in an end station including a user equipment or in a 5G node; and
transmit one or more packets in accordance with a quality of service at the scheduled gate time using the at least one quality of service parameter indicative of the scheduled gate timing for transmission and/or reception.
9 . The apparatus of claim 8 , is further configured to create a quality of service flow in accordance with the at least one quality of service parameter indicative of the scheduled gate timing for transmission and/or reception at the 5G node on the time sensitive communication.
10 . The apparatus of claim 8 , wherein the 5G node comprises a base station and/or a user plane function.
11 . The apparatus of claim 8 , wherein the at least one quality of service parameter indicative of the scheduled gate timing is determined based on a transport delay between the talker end station and the listener end station, and/or wherein the end station including the user equipment comprises the talker end station.
12 . The apparatus of claim 8 , wherein the end station including the user equipment directly couples to a user plane function via an N6 interface, and/or wherein the 5G node comprises a gNB.
