Description

Technical Field

[0001] The present invention belongs to the field of 5G-TSN resource configuration and relates to a 5G side service flow resource configuration method for 5G-TSN integration. Background Art

[0002] As industrial production continues to transform and upgrade towards digitalization, networking, and intelligence, new industrial Internet businesses represented by remote collaborative control, digital twin operation and maintenance, smart factory management, and smart park operations are emerging in an endless stream. New business forms have a profound impact on the communication model of traditional industrial enterprise networks, and the access of new networks such as 5G and TSN has provided new vitality for smart factories.

[0003] 5G has the characteristics of large bandwidth, low latency, and high reliability. It can meet the flexible mobility and differentiated business processing capabilities of industrial equipment and help the large-scale popularization of flexible production in factories. However, industrial applications may require the network to have deterministic latency, jitter, and higher reliability, which brings unprecedented challenges to 5G. Time-Sensitive Networking (TSN) can provide deterministic latency forwarding for services with strong real-time requirements and is compatible with Ethernet protocols. It is favored by the industrial control network field; however, with the application of massive sensors and intelligent devices such as AGV in smart factories, the demand for wireless access and mobile connection of industrial terminals has become more urgent. Wired TSN is difficult to meet the digitalization and intelligence needs of smart factories. The integration of 5G and TSN is an important evolution trend of smart factory networks.

[0004] When 5G and TSN are integrated, how to obtain 5G network resource requirements is one of the key factors to ensure real-time and reliable network transmission. How to configure the service flow resources on the 5G side mainly depends on the latency and jitter requirements of 5G. The latency and jitter of the service flow transmission on the 5G side are obtained through the end-to-end latency and jitter requirements of the service flow and the latency and jitter of the service flow transmission on the TSN side. At present, there is little research on the configuration of 5G service flow resources after 5G-TSN integration at home and abroad. Because different industrial scenarios have different transmission requirements for 5G-TSN, it is impossible to obtain many requirements for 5G side service flow resource configuration by directly using existing methods. Summary of the invention

[0005] In view of this, the object of the present invention is to provide a 5G side service flow resource configuration method for 5G-TSN integration.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides a 5G side service flow resource configuration method for 5G-TSN fusion, which is a network architecture based on 5G-TSN fusion, wherein the network architecture is composed of a software-defined network centralized controller (Software-Defined Networking Controller, SDNC), a centralized network configuration (Centralized Network Configuration, CNC), 5G and TSN. TSN includes TSN1 and TSN2, wherein TSN1 is composed of multiple TSN terminals, multiple TSN switches and a device-side converter (Device-Side TSN Translator, DS-TT), and TSN2 is composed of multiple TSN terminals and multiple TSN switches. 5G includes user equipment (User Equipment, UE), a radio access network ((Radio) Access Network, (R) AN) and a core network with a time-sensitive network application function (Time-Sensitive Networking Application Function, TSNAF), and the core network includes a user interface function UPF and a network-side TSN converter (NW-TT).

[0008] The present invention provides a 5G side service flow resource configuration method for 5G-TSN integration, comprising the following steps:

[0009] S1: The user measures the maximum latency and maximum absolute jitter of each service flow in TSN transmission under different proportions of high-priority service flows, medium-priority service flows, and low-priority service flows according to the test environment set up;

[0010] S2: The user enters the service flow in the SDNC, and the SDNC divides the service flow into high, medium, and low priority service flows according to the priority tags on the TSN VLAN;

[0011] S3: SDNC sets five modes and enters different modes according to the proportion of high, medium and low priority service flows in the service flow;

[0012] S4: SDNC calculates the maximum empirical value of the delay and the maximum empirical absolute value of the jitter for each service flow transmitted in TSN in different modes;

[0013] S5: The user enters the end-to-end delay and jitter of each service flow in SDNC;

[0014] S6: SDNC calculates the maximum value of the transmission delay and the maximum absolute value of the jitter on the 5G side based on the end-to-end delay and jitter of each service flow and the maximum empirical value of the transmission delay and the maximum empirical absolute value of the jitter on the TSN side.

[0015] Further, the test environment described in step S1 includes a PC, a tester, a TSN terminal 1, a TSN terminal 2, a device-side TSN converter DS-TT, and a network-side TSN converter NW-TT; wherein the PC is connected to the tester, the tester is connected to the TSN switch 1, the TSN switch 1 is connected to the DS-TT, the DS-TT is connected to the NW-TT, the NW-TT is connected to the TSN switch 2, and the TSN switch 2 is connected to the tester; the tester has the function of receiving and sending TSN data packets, the tester sends data packets to the TSN switch 1, the TSN switch 1 forwards the data packets to the DS-TT, the DS-TT forwards the data packets to the NW-TT, the NW-TT forwards the data packets to the TSN switch 2, and the TSN switch 2 sends the data packets back to the tester, and the transmission delay and jitter from the TSN terminal 1 to the TSN terminal 2 are checked through the PC.

[0016] Further, in step S1, the user measures the maximum delay and maximum absolute jitter of k service flows in TSN under different proportions of high-priority service flows, medium-priority service flows and low-priority service flows according to the built test environment, k∈n, n is the maximum number of service flows that can be transmitted in 5G-TSN; the gating cycle is cycle, the proportions of high-priority service flows, medium-priority service flows and low-priority service flows are recorded as hper, mper and lper respectively, and the user divides the measurement into the following five cases according to the different proportions of high-priority service flows, medium-priority service flows and low-priority service flows:

[0017] Case 1: When the proportion of high-priority service flows is 100%, the proportion of medium-priority service flows is 100%, or the proportion of low-priority service flows is 100%, the maximum delay and the maximum absolute jitter of the service flows transmitted in TSN are measured and the measurement results are recorded in the table.

[0018] Case 2: When the proportion of high-priority service flows and the proportion of medium-priority service flows are not 0 and the proportion of low-priority service flows is 0, measure the maximum delay and maximum absolute jitter of the service flows transmitted in TSN and record the measurement results.

[0019] Case 3: When the proportion of high-priority service flows and the proportion of low-priority service flows are not 0 and the proportion of medium-priority service flows is 0, measure the maximum delay and maximum absolute jitter of the service flows transmitted in TSN and record the measurement results.

[0020] Case 4: When the proportion of medium-priority service flows and the proportion of low-priority service flows are not 0 and the proportion of high-priority service flows is 0, measure the maximum delay and maximum absolute jitter of the service flows transmitted in TSN and record the measurement results.

[0021] Case 5: When the proportion of high-priority service flows, the proportion of medium-priority service flows, and the proportion of low-priority service flows are all non-zero, the maximum delay and the maximum absolute value of jitter of the service flows transmitted in TSN are measured and the measurement results are recorded.

[0022] Further, in step S2, the user inputs k service flows in the SDNC, and inputs the priority of each service flow in the VLAN tag of the TSN; the SDNC divides the service flows into three categories: high, medium, and low according to the priority of each service flow in the VLAN tag of the TSN, where the high priority service flow corresponds to priorities 7 and 6 in the TSN, the medium priority service flow corresponds to priorities 5, 4, and 3 in the TSN, and the low priority service flow corresponds to priorities 2, 1, and 0 in the TSN.

[0023] Further, in step S3, the SDNC records the number of high-priority service flows, medium-priority service flows, and low-priority service flows according to the transmission priority of each service flow; the number of high-priority service flows, medium-priority service flows, and low-priority service flows are recorded as hn, mn, and ln, respectively, and the proportion of the number of high-priority service flows, medium-priority service flows, and low-priority service flows is recorded as Hper, Mper, and Lper, respectively, and the calculation is shown in expressions (1), (2), and (3):

[0222] With the continuous integration and development of industrialization and informatization, in actual factory networks, the network that carries business flow transmission urgently needs to be composed of different networks. In such heterogeneous networks, the premise for the network to carry out data transmission and deterministic scheduling is to clarify the network configuration requirements. Figure 1 As shown in the figure, this scheme innovatively proposes a network architecture for 5G-TSN integration, which consists of a software-defined network centralized controller (SDNC), a centralized network configuration (CNC), 5G and TSN. TSN includes TSN1 and TSN2, where TSN1 consists of multiple TSN terminals, multiple TSN switches and device-side converters (DS-TT), and TSN2 consists of multiple TSN terminals and multiple TSN switches. 5G includes user equipment (UE), radio access network (RAN) and a core network with a time-sensitive network application function (TSN AF), and the core network includes UPF and network-side TSN converter (NW-TT).

[0223] When 5G and TSN are integrated, the requirements of end-to-end service flow determinism, latency, priority, etc. are known. How to configure latency and jitter for the above end-to-end service flow in the 5G system according to different situations is an urgent problem to be solved. The schematic diagram of the service flow resource configuration method on the 5G side of this solution is as follows Figure 2 shown.

[0224] In different industrial application scenarios, the service flow transmission requirements involved are different. SDNC divides service flows into three categories: high priority service flows, medium priority service flows, and low priority service flows according to the priority of TSN VLAN tags. TSN has 8 priorities from 0 (lowest) to 7 (highest). High priority service flows correspond to priorities 7 and 6 in TSN, medium priority service flows correspond to priorities 5, 4, and 3 in TSN, and low priority service flows correspond to priorities 2, 1, and 0 in TSN.

[0225] Table 1

[0226]

[0227] This solution combines the service flow transmission priority, delay, and jitter information, based on the 802.1Qcc protocol and the new network element functions proposed based on 3GPP R16, to analyze the 5G side transmission delay and jitter of different industrial service flows.

[0228] This process is based on the cross-network time synchronization of 5G-TSN. The specific process can be divided into the following six parts: (1) This solution measures the maximum delay and maximum absolute jitter of each service flow in TSN transmission under different proportions of high-priority service flows, medium-priority service flows and low-priority service flows according to the established test environment; (2) The user enters the service flow in SDNC, and SDNC divides the service flow into high-, medium- and low-priority service flows according to the priority tag on the TSN VLAN; (3) SDNC sets five modes and enters different modes according to the proportion of high-, medium- and low-priority service flows in the service flow; (4) SDNC calculates the maximum empirical value of delay and the maximum empirical absolute value of jitter of each service flow in TSN transmission under different modes; (5) The user enters the end-to-end delay and jitter of each service flow in SDNC; (6) SDNC calculates the maximum delay and the maximum absolute value of jitter transmitted on the 5G side based on the end-to-end delay and jitter of each service flow and the maximum empirical value of delay and the maximum empirical absolute value of jitter transmitted on the TSN side.

[0229] The specific analysis flow chart of the 5G side service flow resource configuration method is as follows Figure 3 shown.

[0230] The 5G-TSN fusion 5G side service flow resource configuration specifically includes the following steps:

[0231] Step 1: This solution measures the maximum latency and maximum absolute jitter of each service flow in TSN transmission under different proportions of high-priority service flows, medium-priority service flows, and low-priority service flows based on the established test environment.

[0232] TSN latency and jitter refer to the latency and jitter of data packets transmitted from TSN terminal 1 to TSN terminal 2. Figure 4 The TSN latency and jitter measurement topology is physically constructed. The tester has the function of sending and receiving TSN data packets, which is equivalent to TSN terminal 1 and TSN terminal 2. The tester is connected to TSN switch 1, TSN switch 1 is connected to DS-TT, DS-TT is connected to NW-TT, NW-TT is connected to TSN switch 2, and TSN switch 2 is connected to the tester. The tester sends a data packet to TSN switch 1, TSN switch 1 forwards the data packet to DS-TT, DS-TT forwards the data packet to NW-TT, NW-TT forwards the data packet to TSN switch 2, and TSN switch 2 sends the data packet back to the tester. The transmission latency and jitter from TSN terminal 1 to TSN terminal 2 can be viewed through the tester software on the PC.

[0233] In this solution, users measure the maximum delay and maximum absolute jitter of k (k∈n, n is the maximum number of service flows that can be transmitted in 5G-TSN) service flows in TSN under different proportions of high-priority service flows, medium-priority service flows and low-priority service flows according to the test environment built. The gating cycle is cycle, and the proportions of high-priority service flows, medium-priority service flows and low-priority service flows are recorded as hper, mper and lper respectively. Users divide the measurement into the following five cases according to the different proportions of high-priority service flows, medium-priority service flows and low-priority service flows:

[0234] Case 1: When the proportion of high-priority service flows is 100%, the proportion of medium-priority service flows is 100%, or the proportion of low-priority service flows is 100%, the maximum delay and maximum absolute jitter of the service flows transmitted in TSN are measured and recorded in the table, as shown in Table 2.

[0235] Table 2

[0236]

[0237] Case 2: When the proportion of high-priority service flows and the proportion of medium-priority service flows are not 0 and the proportion of low-priority service flows is 0, the maximum delay and maximum absolute jitter of the service flows transmitted in TSN are measured and recorded in the table, as shown in Table 3.

[0238] Table 3

[0239]

[0240]

[0241] Case 3: When the proportion of high-priority service flows and the proportion of low-priority service flows are not 0 and the proportion of medium-priority service flows is 0, the maximum delay and maximum absolute jitter of the service flows transmitted in TSN are measured and recorded in the table, as shown in Table 4.

[0242] Table 4

[0243]

[0244] Case 4: When the proportion of medium-priority service flows and the proportion of low-priority service flows are not 0 and the proportion of high-priority service flows is 0, the maximum delay and the maximum absolute value of jitter transmitted by the service flows in TSN are measured and recorded in the table, as shown in Table 5.

[0245] Table 5

[0246]

[0247]

[0248] Case 5: When the proportion of high-priority service flows, the proportion of medium-priority service flows, and the proportion of low-priority service flows are not 0, the maximum delay and the maximum absolute value of jitter transmitted by the service flows in TSN are measured and recorded in the table, as shown in Table 6.

[0249] Table 6

[0250]

[0251]

[0252] SDNC records the maximum transmission delay and maximum absolute jitter of each service flow on the TSN side under different proportions of high-priority service flows, medium-priority service flows, and low-priority service flows.

[0253] Step 2: The user enters k service flows in SDNC and enters the priority of each service flow's VLAN tag in TSN as shown in Table 7. SDNC divides the service flows into three categories: high, medium, and low according to the priority of each service flow's VLAN tag in TSN.

[0254] Table 7

[0255]

[0256] Step 3: Set five modes in SDNC. SDNC enters different modes according to the proportion of high, medium and low priority service flows in the service flow.

[0257] SDNC records the number of high-priority service flows, medium-priority service flows, and low-priority service flows according to the transmission priority of each service flow. The number of high-priority service flows, medium-priority service flows, and low-priority service flows are recorded as hn, mn, and ln, respectively, and the proportion of the number of high-priority service flows, medium-priority service flows, and low-priority service flows is recorded as Hper, Mper, and Lper, respectively, and the calculation is shown in expressions (1), (2), and (3):

[0258]

[0259]

[0260]

[0261] SDNC selects different transmission modes according to the proportion of high-priority service flows, medium-priority service flows, and low-priority service flows, as shown in Table 8.
