Method, device and storage medium for quality of service (QoS) flow management of time sensitive data for transmission of ethernet packet filter sets

A method for Quality of Service (QoS) flow management, performed by a second device, the method comprising:

• receiving a session creation request from a first device;
• creating a first QoS flow according to the session creation request and a QoS management policy, the first QoS flow corresponding to a first extended Ethernet packet filter set, and the first extended Ethernet packet filter set comprising first network type information, first information indicating a transmission characteristic, and attribute information of a protocol header field of a Precision Time Protocol (PTP) or general Precision Time Protocol (gPTP);
• and
• transmitting the first extended Ethernet packet filter set to the first device,
• wherein the first information includes a data type of first data corresponding to the first extended Ethernet packet filter set, and
• wherein the attribute information comprises at least one of the following:
• a domainNumber, a standardization development organization identity, a source port identity, or versionPTP information.

A device for data transmission, comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• first determining code configured to cause the at least one processor to determine, according to network type information included in an extended Ethernet packet filter set, that transmission data is Time Sensitive Communication (TSC) data, the extended Ethernet packet filter set comprising attribute information of a protocol header field of a Precision Time Protocol (PTP) or general Precision Time Protocol (gPTP);
• second determining code configured to cause the at least one processor to determine, according to the extended Ethernet packet filter set, a transmission characteristic of the TSC data;
• mapping code configured to cause the at least one processor to map, according to the transmission characteristic, the TSC data to a Quality of Service (QoS) flow corresponding to the transmission characteristic based on a data type of the TSC data and the attribute information of the TSC data;
• and
• transmission code configured to cause the at least one processor to transmit the TSC data based on the QoS flow, wherein
• the second determining code is further configured to cause the at least one processor to determine, based on the data type of the TSC data being an event type, that the transmission characteristic of the TSC data is a first characteristic, and
• the mapping code is further configured to cause the at least one processor to map, based on the TSC data belonging to first attribute information and the data type being the event type, the TSC data to a first QoS flow corresponding to the first characteristic for transmission.
