Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other without conflict.

Please refer to FIG. 1 , which is a schematic flowchart of a delay measurement method provided by an embodiment of the present disclosure. This delay measurement method is applied to the PCF (Policy Control Function) network element in the converged network element. The converged network element communicates with the centralized network configuration. The converged network element also includes the SMF (Session Management Function) network element and the UPF (User Plane Function). ) network element, the method may include steps S101 to S104.

Step S101: Receive a first service quality monitoring request.

The converged network element can receive the first service quality monitoring request through its own TSN AF network element, and the PCF network element can receive the first service quality monitoring request from the TSN AF network element.

The converged network element is obtained by integrating the TSN AF network element into the NEF network element in the form of microservices. In other words, the TSN AF network element becomes part of the NEF network element, and the resulting converged network element includes the functions of the TSN AF network element and the NEF network element; between the TSN AF network element and the NEF network element Data packet transmission between devices no longer requires the N33 interface, which improves signal transmission efficiency.

In order to facilitate understanding of the advantages of the converged network element in the embodiment of the present disclosure compared to the separate deployment of TSN AF network element and NEF network element, reference can be made to Figure 2. Figure 2 shows the TSN AF network element and NEF network element provided for implementing this embodiment. Schematic diagram of separate deployment of network elements. As can be seen from Figure 2, the signal at the TSN AF network element needs to be transmitted to the NEF network element through the N33 interface, and then transmitted from the NEF network element to the PCF network element. In the converged network element, since the TSN AF network element has become a part of the NEF network element, the TSN AF network element and the NEF network element communicate within the converged network element and do not require the N33 interface, which improves the signal to a certain extent. transmission efficiency.

Before performing this step S101, the delay interval of the 5GS TSN logical bridge can be pre-configured on the converged network element. Pre-configuration can include file configuration or database configuration.

In addition, converged network elements can also subscribe to QoS Monitoring (QoS monitoring) capabilities through their own NEF network elements. In this embodiment of the present disclosure, please refer to Figure 3, which is a schematic diagram of the connection between the 5GS TSN network logical bridge and the TSN network provided by the embodiment of the present disclosure; the converged network element (that is, the TSN AF+ in Figure 3 NEF) is deployed in 5GS, thereby providing a variety of 5G network capabilities. QoS monitoring of UL/DL packet delays between RAN equipment and UPF can be performed at different granularity levels, i.e. QoS flow per UE level or per GTP-U path level, depending on operator configuration, third-party One of the PCF policy controls for application requests and URLLC services.

As shown in Figure 3, the 5GS TSN logical bridge can include UE, RAN equipment, UPF network elements, AMF network elements, SMF network elements, PCF network elements, UDM network elements and converged network elements, etc.

Among them, UE and RAN equipment can communicate directly, UE and UPF network elements can communicate, RAN equipment and UPF network elements can communicate, and UPF network elements and SMF network elements can communicate through the N4 interface. For communication, AMF network elements and SMF network elements can communicate through the N11 interface, AMF network elements and UDM network elements can communicate through the N8 interface, and SMF network elements and UDM network elements can communicate through the N10 interface. SMF network elements can communicate with PCF network elements through the N7 interface, and PCF network elements can communicate with converged network elements. The converged network element also communicates with the CNC network element to report the measured delay data to the CNC.

It can be understood that UPF network elements can be co-located with NW-TT, and terminal nodes can be co-located with DS-TT. One or more ports can be enabled on the NW-TT of the UPF, and the ports on the DS-TT can be associated with the ports of the NW-TT co-located with the UPF. The DS-TT port becomes a port of the 5GS TSN logical bridge. Both the DS-TT port and the NW-TT port can be connected to the TSN Bridge (TSN Bridge) and/or End Station (End Station) respectively. Through the 5GS TSN logical bridge, the TSN bridge and/or terminal station connected to the port of DS-TT or NW-TT can communicate.

The converged network element and the CNC network element can send relevant information about TSN services to the 5G core network control plane. The 5G core network element receives the service information from the converged network element's own TSN AF and maps it to QoS in the 5G system. , and generate TSCAI auxiliary information and pass it to the wireless network to ensure the TSN deterministic service requirements.

Step S102: In response to the first service quality monitoring request, generate a service quality monitoring policy.

The PCF network element may respond to the first service quality monitoring request and generate a service quality monitoring policy according to the PCF network element's own policy control.

The converged network element can send the first service quality monitoring request to the credit domain (PCF network element) through its own TSN AF. Generally, the first service quality monitoring request may include a series of parameters such as the target data network name, application, and application location. The PCF network element can generate policies and charging rules (ie PCC) for the target PDU session service flow based on these information parameters and its own policy control. Among them, the policy and billing rules include service quality monitoring policy.

Step S103: Send the service quality monitoring policy to the session management function network element, so that the session management function network element sends a second service quality monitoring request to the user plane function network element; wherein, the first The second service quality monitoring request is used to instruct the user plane functional network element to monitor the delay between the user plane functional network element and the user equipment to obtain delay data, and the delay data is used to report to the centralized network configuration .

In this step S103, the session management function (ie SMF) network element can respond to the second service quality monitoring request, generate a second service quality monitoring request, and send the second service quality monitoring request to the UPF network element through N4 signaling; UPF The network element monitors the delay between the UPF network element and the RAN device (or NG-RAN) according to the second service quality monitoring request, and obtains delay data.

Further, the second service quality monitoring request is used to cause the user plane functional network element to monitor the uplink/downlink delay between the user equipment and the user plane functional network element during the establishment of the protocol data unit session. Alternatively, the second service quality monitoring request is used to cause the user plane functional network element to monitor the uplink/downlink delay between the user equipment and the user plane functional network element during the protocol data unit session modification process.

In embodiments of the present disclosure, the second service quality monitoring request may include monitoring parameters determined by the session management function network element according to the service quality monitoring policy.

It can be understood that delay can refer to the time for a data packet to pass from one port to another port, and the PDB in RAN equipment (or NG-RAN) is the end-to-end delay, that is, from the UE to the UPF network element. delay.

Generally speaking, the signal sent by the base station will experience a certain propagation delay when it reaches the UE through the air. The port of the device-side time-sensitive network adapter (DS-TT) can be the data outgoing port, and the network-side time-sensitive network adapter (NW-TT) can be the outbound port of the data. The port of TT) is the inlet port for data, and there will also be a delay when data packets pass from one port to another. Therefore, the delay data between the UE and the UPF network element may include: the time for the data packet to be transmitted from the UPF network element to the RAN device, and the time for the data packet to be transmitted from the RAN device to the UE. In other words, the delay data between the UE and the UPF network element includes: DOWNLINK between the UE and the UPF network element, UPLINK between the UE and the UPF network element, and ROUND_TRIP (round trip) between the UE and the UPF network element. ), thus obtaining the packet delay of the entire 5GS as a network bridge, which is also the delay data.

Furthermore, the delay data can also be used to update the bridge delay interval in the converged network element.

In addition, embodiments of the present disclosure may also include: the converged network element may receive delay data and report the delay data to the CNC network element. The delay data may be delay data triggered by the PCF network element according to conditions. Conditional triggering can include: immediate triggering, periodic triggering, and session release triggering.

Immediate triggering can be: monitoring delay data at all times.

Periodic triggering can be: monitoring the delay data every preset time interval.

The session release trigger can be: every time a session occurs (which can be understood as data plane interaction), the delay data is monitored.

In the converged network element of the delay measurement method provided in the above embodiment, since the TSN AF network element has become a part of the NEF network element, the TSN AF network element and the NEF network element communicate within the converged network element and do not require N33 interface, which improves signal transmission efficiency to a certain extent; and the SMF network element generates a service quality monitoring policy by receiving the first service quality monitoring request; sends the service quality monitoring policy to the SMF network element, so that the SMF network element reports to UPF The network element sends a second service quality monitoring request to monitor the delay between the UPF network element and the UE, and obtain delay data.

Please refer to Figure 4. The embodiment of the present disclosure also provides a delay measurement method, in which the NEF network element in the converged network element can subscribe to the QoS monitoring capability, so that the UPF network element can have monitoring capabilities, and the PCF network element can subscribe to the QoS monitoring capability from the converged network element. The TSN AF network element in the element receives the first quality of service monitoring request, generates a QoS monitoring policy, and sends it to the SMF network element. The SMF network element can generate a second quality of service monitoring request according to the QoS monitoring policy and sends it to the UPF network. At the element, the UPF network element monitors the delay between the UPF network element and the UE according to the second service quality monitoring request.

Please refer to Figure 5. Figure 5 is another delay measurement method provided by an embodiment of the present disclosure. It is applied to the SMF network element in the converged network element.
