It should be noted that the number and the form of the network elements shown in fig. 2 do not limit the embodiment of the present application, and fig. 2 takes one transmitting end, one receiving end, and three switching nodes as examples, and may include multiple transmitting ends, multiple receiving ends, or one switching node in practical application.

The switching node reserves resources for the TSN stream according to the definition of the TSN standard, and schedules and forwards the TSN stream.

And the CNC network element is responsible for managing the topology of the TSN user plane and the capability information of the switching nodes, creating the TSN stream according to the TSN stream creation request provided by the CUC network element, generating a forwarding path of the TSN stream and processing strategies on the data terminal and each switching node, and then issuing the processing strategies on the switching nodes to the corresponding switching nodes. The capability information of the switch node may include, for example, a transmission delay of the switch node and an internal processing delay between ports of the switch node, where the transmission delay refers to a time elapsed from the time when the TSN stream is transmitted from the port of the switch node to the time when the TSN stream reaches the port of the opposite switch node; the internal processing delay refers to the time which passes from the time when one port of the switching node enters to the time when the other port of the switching node exits. The processing policy at the switching node may include, for example, ports and time slices for transceiving the TSN stream, where a time slice refers to time information for transceiving the TSN stream by the switching node, and for example, the TSN stream is received within time t1 to time t 2.

And the CUC network element is used for collecting the TSN stream creation request of the data terminal, requesting the CNC network element to create the TSN stream after matching the requests of the sending end and the receiving end, and confirming the processing strategy generated by the CNC network element. The matching of the requests of the sending end and the receiving end refers to TSN stream creation requests sent by the sending end and the receiving end to the CUC network element respectively, the TSN stream creation requests include some information, such as destination MAC addresses of the requested TSN streams, the CUC network element matches the TSN stream creation requests with destination MAC addresses of TSN streams requested by different data terminals, if the destination MAC addresses of the TSN streams requested by two data terminals are the same, the same TSN stream requested by the two data terminals is successfully matched, and the CNC network element can create the TSN stream; otherwise, only the TSN stream creation request of the sending end or the receiving end is needed, the CUC network element cannot request the CNC network element to create the TSN stream, and the CNC network element cannot create the TSN stream.

It is understood that the CNC network element and the CUC network element are control plane network elements in the TSN.

In order to implement end-to-end deterministic transmission in a fifth generation mobile communication (5th-generation, 5G) system, an assumption is made that the 5G system can be virtualized as a switching node in a TSN and the function of the switching node in the TSN can be implemented.

Specifically, referring to the schematic diagram of the network architecture shown in fig. 3, the 5G architecture shown in fig. 1 and the TSN architecture shown in fig. 2 are combined, TSN converters (DSTT and UPF TT) are respectively arranged on the terminal side and the network UPF side, and are used for executing a flow control principle of the TSN, performing functions of heterogeneous system docking such as clock conversion, and the like, and simultaneously, the TSN AF and the CNC are used for sending relevant information of the TSN service to the 5G core network control plane, including flow classification, period, burst time, and the like, and the 5G core network element receives service information sent by the TSN AF, maps the service information into QoS in the 5G system, generates TSCAI auxiliary information, and transmits the TSCAI auxiliary information to the wireless network, thereby ensuring the requirement of the TSN deterministic service.

Although the network architecture diagram shown in fig. 3 is proposed, the 5G system only guarantees the TSN deterministic service through wireless side scheduling and reliable transmission of the core network, and lacks end-to-end cooperativity, and the air interface jitter and uncertainty are large, the QoS parameter is static, the state of the deterministic service cannot be monitored and adjusted in real time, and the severe TSN service encounters a complex 5G system, and it is difficult to guarantee the performance in the end-to-end 5G system.

Based on the existing 5G and TSN fusion architecture, a network data analysis network element is used for analyzing whether TSN service in a historical time period can meet TSN service requirements by using 5GS QoS parameters, if the TSN service requirements cannot be met, a slice creation request is sent to a network slice management network element through a policy control network element, and the network slice management network element creates a corresponding TSN slice according to the slice creation request. Compared with the prior art that the air interface jitter and the uncertainty are large, the strict deterministic service requirement cannot be met only by scheduling by using the 5GS QoS parameter, the scheme of the application can create the corresponding TSN slice according to the service requirement of the TSN, so that the configuration of the corresponding wireless network, the transmission network and the core network can be issued to the TSN slice, the performance of the TSN slice can be monitored in real time, and the performance of the TSN service can be ensured end to end.

The solution of the present application is explained with respect to the network architecture shown in fig. 3.

The embodiments of the present application will be specifically described below with reference to the accompanying drawings.

As shown in fig. 4, an embodiment of the present application provides a method for processing a TSN, including the following steps:

s101, the application function network element sends TSN QoS information to the strategy control network element.

Wherein the TSN QoS information comprises one or more of the following: TSN type, period, bridge delay, priority, or burst packet size.

Optionally, the application function network element configures respective corresponding TSN QoS information according to different TSN service characteristics.

S102, the strategy control network element maps the TSN QoS information into 5GS QoS parameters.

Optionally, the 5GS QoS parameter includes a 5G QoS indicator (5QI), an Allocation and Retention Priority (ARP), a guaranteed stream bit rate, a maximum bit rate, and the like.

Wherein, 5QI specifies service priority, time delay and packet loss rate, and is mainly used for resource scheduling. The ARP parameter contains information such as priority, preemption capability, and preemption availability. The priority defines the importance of the UE resource request, and the ARP parameter determines whether a new QoS flow is accepted or rejected when system resources are restricted. The value range of the ARP priority is 1-15, and 1 is the highest priority.

As a possible implementation manner, a mapping table is stored in the policy control network element in advance, and the mapping table is used for indicating a corresponding relationship between the TSN QoS and the 5G QoS. And after the strategy control network element receives the TSN QoS information, searching/mapping the corresponding 5G QoS parameters through the mapping table.

S103, the policy control network element sends the QoS parameter of 5GS to the network data analysis network element.

S104, the network data analysis network element analyzes the service performance of the TSN service in the historical time period according to the 5GS QoS parameter to obtain a service performance analysis result.

The Network Data analysis Network element may be a Network Data analysis Function (NWDAF) Network element.

Optionally, the NWDAF network element may be obtained from network elements such as an AMF network element, an SMF network element, a PCF network element, a UDM network element, a NEF network element, an AF network element, and an NRF network element.

Specifically, after receiving the 5GS QoS parameter, the NWDAF network element sends a request signaling carrying the 5GS QoS parameter to each network element, and after receiving the request signaling containing the 5GS QoS parameter, each network element schedules a TSN service using the 5GS QoS parameter in a historical time period and sends the TSN service using the 5GS QoS parameter to the NWDAF network element, so that the NWDAF network element performs service performance analysis on the TSN service in the historical time period according to the 5GS QoS parameter to obtain a service performance analysis result.

Optionally, the service performance analysis result includes that the TSN service usage 5GS QoS parameter in the historical time period can satisfy the TSN service demand or that the TSN service usage 5GS QoS parameter in the historical time period cannot satisfy the TSN service demand,

specifically, the network data analysis network element collects TSN traffic in a historical time period from each network element, and determines whether the TSN traffic in the historical time period satisfies a preset condition by using a 5GS QoS parameter. And if the TSN service in the historical time period can meet the preset condition by using the 5GS QoS parameter, determining that the service performance analysis result is that the TSN service in the historical time period can meet the TSN service requirement by using the 5GS QoS parameter. And if the TSN service usage 5GS QoS parameter in the historical time period can not meet the preset condition, determining that the service performance analysis result is that the TSN service usage 5GS QoS parameter in the historical time period can not meet the TSN service requirement.

Wherein the preset conditions include: the TSN traffic in the historical time period has used the 5GS QoS parameter, or the delay requirement and/or jitter requirement of the TSN traffic in the historical time period matches the 5GS QoS parameter.

And S105, the network data analysis network element sends the service performance analysis result to the strategy control network element.

And S106, if the performance analysis result shows that the TSN service usage in the historical time period is 5GS QoS parameters which cannot meet the TSN service requirement, the strategy control network element sends a slice creation request to the network slice management network element.

Wherein the slice creation request includes TSN QoS information, a 5GS QoS parameter, and a TSN identification.

Optionally, the slice creation request may further include a TSN assistance parameter for assisting configuration and/or transmission of the TSN service.

And S107, the network slice management network element creates a TSN slice according to the slice creation request.

Specifically, the network slice management network element creates a plurality of TSN slices according to the TSN QoS information, the 5GS QoS parameter, and the TSN identifier.

Wherein each TSN slice corresponds to a TSN identifier.

Further, a Network sub-Slice Management Function (NSSMF) in the Network Slice architecture may configure resources for each TSN Slice.

The NSSMF comprises a Core Network sub-Slice Management Function (CN-NSSMF), a carrier Network sub-Slice Management Function (TN-NSSMF) and AN Access Network sub-Slice Management Function (AN-NSSMF).

The CN-NSSMF is mainly responsible for managing and arranging the sub-slice example of the 5G core network, receiving the Management and arrangement requirements of the NSMF on the sub-slice, and calling a Management and arrangement device (MANO) and an Element Management System (EMS) of the core network to manage, arrange and configure parameters of the sub-slice. The functions of the CN-NSSMF include subslice template design, creation/modification/termination of subslice instances, capacity management, fault management, performance management, configuration management, automatic optimization, collaborative management, and the like.

The TN-NSSMF is mainly responsible for the management and the arrangement of the sub-slice instances of the 5G bearer network, meets the management and the arrangement requirements of the NSMF on the sub-slices, and calls an SDN Orchestrator (SDN Orchemirator, SDNO)/SDN Controller (SDN Controller, SDNC) and an EMS of the bearer network to manage, arrange and configure parameters of the sub-slices. The functions of TN-NSSMF include: design of sub-slice templates, creation/modification/termination of sub-slice instances, resource management, fault management, performance management, configuration management, automatic optimization, collaborative management, and the like.

The AN-NSSMF can perform the arranging management according to the MANO mode for the network elements capable of being deployed in a virtualized mode.

In some embodiments, the wireless side may implement the performance of the TSN service end-to-end by combining resource reservation with 5GS QoS parameters; or, the bearer Network side uses TN-NSSMF to implement the performance of the TSN service end to end through a Virtual Private Network (VPN) or a Flexible Ethernet technology (FlexE); or, the core network side realizes the performance of the TSN service end to end by using the CN-NSSMF through a mode of distributing network elements such as special UPF and the like.

Optionally, the network slice management network element may also monitor the performance of the TSN slice in real time.

Illustratively, if it is monitored that the TSN service in a certain TSN slice cannot satisfy the corresponding 5GS QoS parameter using the network resource delivered by each sub-field, the network resource delivered by each sub-field to the TSN slice is adjusted in time, so that the TSN service in the TSN slice satisfies the corresponding 5GS QoS parameter.

The embodiment of the application provides a TSN processing method, on the basis of the existing 5G and TSN fusion architecture, a network data analysis network element is used for analyzing whether TSN services in a historical time period can meet TSN service requirements by using 5GS QoS parameters, if the TSN service requirements cannot be met, a slice creation request is sent to a network slice management network element through a policy control network element, and the network slice management network element creates a corresponding TSN slice according to the slice creation request. Compared with the prior art that the air interface jitter and the uncertainty are large, the strict deterministic service requirement cannot be met only by scheduling by using the 5GS QoS parameter, the scheme of the application can create the corresponding TSN slice according to the service requirement of the TSN, so that the configuration of the corresponding wireless network, the transmission network and the core network can be issued to the TSN slice, the performance of the TSN slice can be monitored in real time, and the performance of the TSN service can be ensured end to end.

In some embodiments, as shown in fig. 5, after S105, the method further comprises:

and S108, if the performance analysis result shows that the TSN service in the historical time period can meet the TSN service requirement by using the 5GS QoS parameter, the policy control network element sends the 5GS QoS parameter to the session management network element.

Optionally, after receiving the 5GS QoS parameter, the session management network element performs corresponding resource scheduling according to the 5GS QoS parameter to ensure the TSN service performance.

Based on the above embodiment, if the performance analysis result is that the TSN service in the historical time period can meet the TSN service demand using the 5GS QoS parameter, it is indicated that the resource scheduling performed according to the 5GS QoS parameter can already meet the service performance of the TSN.

It can be seen that the foregoing describes the solution provided by the embodiments of the present application primarily from a methodological perspective. In order to realize the functions, the monitoring device of the optical cable tube well comprises a hardware structure and/or a software module which are used for executing the corresponding functions.
