Description

Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a method, system, device, and medium for monitoring the quality of service during satellite backhaul. Background Technology

[0002] Quality of Service (QoS) monitoring refers to the real-time measurement of QoS parameters for service data flows. For example, Ultra-Reliable Low-Latency Communication (URLLC) measures the packet latency of QoS flows between the User Equipment (UE) and the User Plane Function (UPF). QoS monitoring can provide better and more predictable network services, offering dedicated bandwidth, controllable jitter and latency, and improved loss characteristics. With the rapid development of satellite communication technology, QoS monitoring during satellite backhaul communication is also crucial.

[0003] However, due to the wide coverage and large number of terminals served by satellite services, if QoS monitoring is also performed in areas without coverage or service, it is necessary to continuously send QoS monitoring messages. Related network elements will also send a lot of request and response messages, resulting in a waste of bandwidth resources. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a method, system, device and medium for monitoring the quality of service during satellite backhaul, so as to solve the problem of bandwidth resource waste during satellite backhaul.

[0005] In a first aspect, embodiments of this application provide a method for monitoring quality of service (QoS) during satellite backhaul, applied to a QoS monitoring system. The QoS monitoring system includes an Access and Mobility Management Function (AMF), a Session Management Function (SMF), a Policy Control Function (PCF), a User Plane Function (UPF), and a Radio Access Network (NG-RAN). The method includes:

[0006] During the satellite backhaul connection process, the AMF receives status information sent by the user terminal, the satellite and the external server, and sends the status information to the SMF. The status information includes terminal coverage information, beam shutdown information and satellite health status detection information.

[0007] After receiving the status information sent by the AMF, the SMF determines whether to perform QoS monitoring based on the status information.

[0008] If it is determined that QoS monitoring should be performed, a QoS monitoring request is generated based on the status information and sent to the PCF.

[0009] After receiving a QoS monitoring request, the PCF generates an authorized QoS monitoring policy based on the QoS monitoring request and sends the QoS monitoring policy to the SMF.

[0010] In response to the monitoring instructions sent by the SMF according to the QoS monitoring policy, the UPF and NG-RAN perform latency measurements and generate a QoS monitoring report based on the latency measurement results.

[0011] Optionally, determining whether to perform QoS monitoring based on status information includes: determining whether the user terminal has lost coverage, whether all satellite beams are turned off, and whether the satellite has malfunctioned based on terminal coverage information, beam shutdown information, and satellite health status detection information; if it is determined that the user terminal has lost coverage, all satellite beams are turned off, and the satellite has malfunctioned, determining not to perform QoS monitoring; otherwise, determining to perform QoS monitoring.

[0012] Optionally, generating an authorized QoS monitoring policy based on the QoS monitoring request includes: obtaining status information from the QoS monitoring request, determining the target monitoring link based on the status information, and generating the QoS monitoring policy based on the target monitoring link.

[0013] Optionally, the target monitoring link is determined based on the status information, including: if the user terminal loses coverage, the communication link corresponding to the user terminal is determined as an unmonitored link; if there is a closed beam of the satellite, all links under the closed beam are determined as unmonitored links; if the satellite malfunctions, all links under the satellite coverage are determined as unmonitored links; and the communication links other than the unmonitored links are taken as the target monitoring links.

[0014] Optionally, a QoS monitoring request is generated based on the status information, including adding terminal coverage information, beam shutdown information, and satellite health status detection information as auxiliary information to the QoS monitoring request.

[0015] Optionally, in response to the monitoring command sent by the SMF according to the QoS monitoring policy, the UPF and NG-RAN perform latency measurement, including: the UPF and NG-RAN perform latency measurement according to the monitoring command, generate a QoS monitoring report based on the latency measurement results, and send the QoS monitoring report to the specified target network element.

[0016] Optionally, before the AMF receives status information sent by the user terminal, satellite, and external server, the method further includes: the external server obtaining satellite health status detection information from the satellite; and sending the satellite health status detection information to the AMF.

[0017] Secondly, this application also provides a service quality monitoring system, which is applied to a service quality monitoring system. The service quality monitoring system includes an access and mobility management function device (AMF), a session management function device (SMF), a policy control function device (PCF), a user plane function device (UPF), and a radio access network (NG-RAN).

[0018] AMF is used to receive status information sent by user terminals, satellites and external servers during satellite backhaul connections, and send the status information to SMF. The status information includes terminal coverage information, beam shutdown information and satellite health status detection information.

[0019] SMF is used to determine whether to perform QoS monitoring based on the status information sent by AMF after receiving the status information. If it is determined to perform QoS monitoring, a QoS monitoring request is generated based on the status information and sent to PCF.

[0020] PCF is used to generate an authorized QoS monitoring policy based on the QoS monitoring request after receiving the QoS monitoring request, and send the QoS monitoring policy to SMF;

[0021] UPF and NG-RAN are used to perform latency measurement in response to monitoring instructions sent by SMF according to QoS monitoring policy, and generate QoS monitoring reports based on the latency measurement results.

[0022] Thirdly, embodiments of this application also provide an electronic device, including: a processor, a memory, and a bus. The memory stores machine-readable instructions executable by the processor. When the electronic device is running, the processor communicates with the memory via the bus. When the machine-readable instructions are executed by the processor, the steps of the service quality monitoring method in satellite backhaul described above are performed.

[0023] Fourthly, embodiments of this application also provide a computer-readable storage medium storing a computer program that, when executed by a processor, performs the steps of the above-described method for monitoring the quality of service during satellite backhaul.

[0024] The embodiments of this application bring the following beneficial effects:

[0025] This application provides a method, system, device, and medium for monitoring quality of service (QoS) during satellite backhaul. It can determine whether to perform QoS monitoring based on terminal coverage information, beam shutdown information, and satellite health status detection information. After determining whether to perform QoS monitoring, it generates a QoS monitoring request and uses the QoS monitoring strategy corresponding to the request for QoS monitoring. Compared with existing methods for monitoring QoS during satellite backhaul, this solves the problem of wasted bandwidth resources during satellite backhaul.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.

[0032] It is worth noting that prior to this application, Quality of Service (QoS) monitoring referred to the actual measurement of QoS parameters of service data streams. For example, Ultra-Reliable Low-Latency Communication (URLLC) measures the packet latency of QoS streams between User Equipment (UE) and User Plane Function (UPF). QoS monitoring can provide better and more predictable network services, offering dedicated bandwidth, controllable jitter and latency, and improved loss characteristics. With the rapid development of satellite communication technology, QoS monitoring during satellite backhaul communication is also crucial. However, due to the wide coverage and large number of terminals served by satellite services, if QoS monitoring is performed in areas without coverage or service, it requires continuous QoS monitoring message transmission. Related network elements will also send numerous request and response messages. For example, the User Plane Function (UPF) may not be able to obtain measurement reports during the monitoring reporting period, thus continuously sending measurement failure reports. These redundant and useless messages burden the communication system and waste bandwidth resources.

[0033] Based on this, embodiments of this application provide a method for monitoring the quality of service during satellite backhaul to improve the utilization of bandwidth resources.

[0034] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for monitoring quality of service during satellite backhaul, provided as an embodiment of this application. Figure 1 As shown in the embodiments of this application, the service quality monitoring method in satellite backhaul is applied to a service quality monitoring system. The service quality monitoring system includes an Access and Mobility Management Function (AMF), a Session Management Function (SMF), a Policy Control Function (PCF), a User Plane Function (UPF), and a Radio Access Network (NG-RAN). The method includes:

[0035] In step S101, during the satellite backhaul connection process, the AMF receives status information sent by the user terminal, the satellite and the external server, and sends the status information to the SMF.

[0036] In this step, AMF refers to the Access and Mobility Management Function (AMF), which is responsible for mobility management.

[0037] SMF stands for Session Management Function (SMF), which is responsible for session management.

[0038] Status information can refer to information sent by user terminals, satellites, and external servers for QoS monitoring. Status information includes terminal coverage information, beam shutdown information, and satellite health status detection information.

[0039] Satellite backhaul refers to communication via satellite access. Its application areas include all communication scenarios involving satellite.

[0040] A user terminal can refer to a terminal device that can communicate with a target satellite. For example, a user terminal can be a smartphone or a smart wearable device.

[0041] In this embodiment, the user terminal and external server corresponding to a single satellite are used for illustration. The user terminal reports its coverage information to the AMF, including whether it has lost coverage or is about to gain coverage. The satellite also broadcasts messages to the AMF in real time, carrying satellite information and including beam shutdown information, which includes the satellite's number and the number of the beam being shut down. The external server also sends the acquired satellite health status detection information to the AMF.

[0042] When the AMF receives terminal coverage information sent by the user terminal, beam shutdown information sent by the satellite, and satellite health status detection information sent by the external server, it provides this information as unified status information to the SMF.

[0043] In one optional embodiment, before the AMF receives status information sent by the user terminal, the satellite, and the external server, the method further includes: the external server obtaining satellite health status detection information from the satellite; and sending the satellite health status detection information to the AMF.

[0044] Here, an external server may refer to a device used for satellite health monitoring; for example, an external server may be a server deployed on a satellite.

[0045] Specifically, the external server uses Prognostics Health Management (PHM) technology to detect and predict satellite faults, obtain satellite health status information, and then sends the obtained satellite health status information to the AMF.

[0046] In step S102, after receiving the status information sent by the AMF, the SMF determines whether to perform QoS monitoring based on the status information.

[0047] In this step, after receiving the status information, the SMF analyzes the terminal coverage information, beam shutdown information, and satellite health status detection information to determine whether QoS monitoring should be performed. If it is determined that QoS monitoring should not be performed, there is no need to generate a QoS monitoring request, reducing unnecessary QoS monitoring message sending and network element request and response message sending.

[0048] In one optional embodiment, determining whether to perform Quality of Service (QoS) monitoring based on status information includes: determining whether the user terminal has lost coverage, whether all beams of the satellite are turned off, and whether the satellite has malfunctioned, based on terminal coverage information, beam shutdown information, and satellite health status detection information, respectively; if it is determined that the user terminal has lost coverage, all beams of the satellite are turned off, and the satellite has malfunctioned, it is determined that QoS monitoring will not be performed; otherwise, it is determined that QoS monitoring will be performed.

[0049] Specifically, when all three conditions are met—the terminal coverage information is lost, the beam shutdown information includes the beam numbers of all beams, and the satellite malfunctions—QoS monitoring is unnecessary because there is no communication link.

[0050] Step S103: If it is determined that QoS monitoring will be performed, a QoS monitoring request will be generated based on the status information and sent to the PCF.

[0051] In this step, PCF refers to the Policy Control Function (PCF), which is responsible for policy control. The PCF is connected to the SMF.

[0052] A QoS monitoring request can refer to an application to initiate QoS monitoring. A QoS monitoring request is used to start QoS monitoring, and QoS monitoring will not be performed if a QoS monitoring request is not initiated.

[0053] In this embodiment of the application, if the conditions for QoS monitoring are met, a QoS monitoring request is generated based on terminal coverage information, beam shutdown information and satellite health status detection information, and the generated QoS monitoring request is sent to the PCF so that the PCF can generate a QoS monitoring policy based on the QoS monitoring request.

[0054] In one optional embodiment, generating a QoS monitoring request based on status information includes adding terminal coverage information, beam shutdown information, and satellite health status detection information as auxiliary information to the QoS monitoring request.

[0055] Specifically, the terminal identifier of the user terminal that has lost coverage, the loss of coverage identifier, the satellite number, the beam number of the closed beam, and the satellite health status detection information are added as auxiliary information to the QoS monitoring request.

[0056] In step S104, after receiving the QoS monitoring request, the PCF generates an authorized QoS monitoring policy based on the QoS monitoring request and sends the QoS monitoring policy to the SMF.

[0057] In this step, after receiving a QoS monitoring request, the PCF generates a corresponding QoS monitoring policy. This policy includes the QoS parameters to be measured, the reporting frequency, and the target monitoring link. The QoS parameters to be measured include, but are not limited to, DL packet delay, UL packet delay, and round-trip packet delay. The reporting frequency is divided into event-triggered reporting and periodic reporting.

[0058] Among them, DL packet refers to Download packet, that is, download data packet, and UL packet refers to Upload packet, that is, upload packet.

[0059] In one optional embodiment, generating an authorized QoS monitoring policy based on a QoS monitoring request includes: obtaining status information from the QoS monitoring request, determining a target monitoring link based on the status information, and generating a QoS monitoring policy based on the target monitoring link.

[0060] Specifically, the terminal identifier, coverage loss identifier, satellite number, beam number of closed beams, and satellite health status detection information of user terminals that have lost coverage are extracted from the QoS monitoring request. Based on the extracted information, it is determined which communication links need to be monitored, and the communication links that need to be monitored are designated as target monitoring links. Based on the determined target monitoring links, the QoS parameters to be measured, and the reporting frequency, a QoS monitoring strategy is generated.

[0061] In one optional embodiment, determining the target monitoring link based on the status information includes: if the user terminal loses coverage, determining the communication link corresponding to the user terminal as an unmonitored link; if the satellite has a closed beam, determining all links under the closed beam as unmonitored links; if the satellite malfunctions, determining all links under the satellite coverage as unmonitored links; and taking the communication links other than the unmonitored links as the target monitoring links.

[0062] Specifically, if it is determined that a user terminal has lost coverage, it means that the user terminal can no longer communicate with the satellite and there is no need for QoS monitoring. In this case, the communication link corresponding to the user terminal is designated as an unmonitored link based on the terminal identifier.

[0063] If a satellite has a closed beam, it means that the beam is no longer in use and there is no need to monitor the QoS of the beam. Therefore, based on the satellite number and the beam number of the closed beam, all links under that beam are treated as unmonitored links.

[0064] If a satellite is confirmed to be malfunctioning, it means that the satellite is unable to communicate and there is no need to monitor the QoS of the satellite. Therefore, all links under the coverage of the satellite are designated as unmonitored links.

[0065] Once the links that are not to be monitored are determined, the communication links other than those not to be monitored will be designated as the target monitoring links.

[0066] In step S105, in response to the monitoring command sent by the SMF according to the QoS monitoring policy, the UPF and NG-RAN perform latency measurement and generate a QoS monitoring report based on the latency measurement results.

[0067] In this step, the SMF sends monitoring notification messages to the UPF and NG-RAN according to the QoS monitoring policy sent by the PCF in order to perform QoS monitoring.

[0068] UPF can refer to User Plane Function (UPF).

[0069] NG-RAN can refer to NG Radio Access Network (NG-RAN).

[0070] In one optional embodiment, in response to the monitoring command sent by the SMF according to the QoS monitoring policy, the UPF and NG-RAN perform latency measurement, including: the UPF and NG-RAN perform latency measurement according to the monitoring command, generate a QoS monitoring report based on the latency measurement results, and send the QoS monitoring report to the designated target network element.

[0071] Specifically, after receiving the QoS monitoring policy from the PCF, the SMF sends monitoring instructions to the UPF and NG-RAN respectively according to the QoS monitoring policy. The NG-RAN and UPF perform latency measurements on the target monitoring link according to the monitoring instructions. The NG-RAN reports the latency measurement results to the UPF, which generates a QoS monitoring report based on the latency measurement results and sends the QoS monitoring report to the target network element. The target network element is specified by the PCF through instruction information. The UPF directly sends the QoS monitoring report to the target network element according to this instruction information. For example, the target network element might be the SMF that sent the QoS monitoring request.

[0072] Compared with existing methods for monitoring the quality of service (QoS) during satellite backhaul, this application can determine whether to perform QoS monitoring based on terminal coverage information, beam shutdown information, and satellite health status detection information. After determining whether to perform QoS monitoring, it generates a QoS monitoring request and uses the QoS monitoring policy corresponding to the QoS monitoring request to perform QoS monitoring, thus solving the problem of wasted bandwidth resources during satellite backhaul.

[0073] Based on the same inventive concept, this application also provides a service quality monitoring system corresponding to the service quality monitoring method in satellite backhaul. Since the principle of the system in this application is similar to the service quality monitoring method in satellite backhaul described above, the implementation of the system can refer to the implementation of the method, and the repeated parts will not be described again.

Figure 2 As shown, the Quality of Service (QoS) monitoring system 200 includes an Access and Mobility Management Function (AMF) 201, a Session Management Function (SMF) 202, a Policy Control Function (PCF) 203, a User Plane Function (UPF) 204, and a Radio Access Network (NG-RAN) 205.

[0075] AMF201 is used to receive status information sent by user terminals, satellites and external servers during satellite backhaul connection, and send the status information to SMF202. The status information includes terminal coverage information, beam shutdown information and satellite health status detection information.

[0076] SMF202 is used to determine whether to perform QoS monitoring based on the status information after receiving the status information from AMF. If it is determined to perform QoS monitoring, a QoS monitoring request is generated and sent to PCF203.

[0077] PCF203 is used to generate an authorized QoS monitoring policy based on the QoS monitoring request after receiving the QoS monitoring request, and send the QoS monitoring policy to SMF202.

[0078] UPF204 and NG-RAN205 are used to perform latency measurement in response to monitoring instructions sent by SMF according to QoS monitoring policy, and generate QoS monitoring reports based on the latency measurement results.

[0080] The memory 320 stores machine-readable instructions executable by the processor 310. When the electronic device 300 is running, the processor 310 and the memory 320 communicate via the bus 330.
