Description

Methods and apparatus for data measurement

[0001] This application claims priority to Chinese Patent Application No. 202311652181.1, filed on December 4, 2023, entitled "Method and Apparatus for Data Measurement", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more specifically, to a method and apparatus for data measurement. Background Technology

[0003] In QoS monitoring of wireless networks, wireless network maintenance personnel need to manually obtain the flow identification information of the service data to be measured and manually control the initiation of flow measurement. After the communication devices in the wireless network measure the service data, they report the measurement results to the network management device, which then determines the QoS of the wireless network based on the measurement results. Similarly, in QoS monitoring of bearer networks, bearer network maintenance personnel also need to manually obtain the flow identification information of the service data to be measured and manually control the initiation of flow measurement. After the communication devices in the bearer network measure the service data, they report the measurement results to the network management device, which then determines the QoS of the bearer network based on the measurement results.

[0004] When the transmission of service data needs to pass through both wireless and bearer networks, the different networks cannot communicate with each other due to the inconsistency in the encapsulation format and flow identifier definition of service data in the wireless and bearer networks. Therefore, it is impossible to achieve end-to-end (device-to-device) automatic transmission measurement between the wireless and bearer networks. Summary of the Invention

[0005] This application provides a method and apparatus for data measurement, which can realize automatic end-to-end (device-to-device) measurement on wireless networks and bearer networks.

[0006] In a first aspect, a data measurement method is provided. This method can be applied to a first transmission device in a bearer network. For example, it can be executed by the first transmission device, or by a component (such as a chip, chip system, etc.) configured in the first transmission device, or by a logic module or software that can implement all or part of the functions of the first transmission device. This application does not limit this.

[0007] For example, the method includes: a first transmission device receiving control information and service data, the control information including at least one of first stream identification information, measurement method information, measurement period information, or measurement type information of the service data, wherein the first stream identification information is the stream identification information of the service data in the wireless network; the first transmission device measuring the service data according to the control information to obtain first measurement result information; and the first transmission device sending the first measurement result information to a first network management device.

[0008] Based on the above technical solution, the wireless access network device or core network device in the wireless network can send control information for measuring service data to the transmission device (first transmission device) in the bearer network. The transmission device in the bearer network can then automatically measure the service data from the wireless network based on this control information. Compared to the transmission measurement scheme where wireless network maintenance personnel and bearer network maintenance personnel manually input flow identification information, this application can achieve end-to-end (device-to-device) automatic measurement between the wireless network and the bearer network.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: the first transmission device converting the first flow identification information into second flow identification information, the second flow identification information being the flow identification information of the service data in the bearer network, wherein the first measurement result information includes the mapping relationship between the first flow identification information and the second flow identification information.

[0010] Optionally, the unified network management device can assign unified flow identification information, ensuring that the flow identification information for service data is the same in both the wireless network and the bearer network. In this optional scheme, the first transmission device does not need to convert the flow identification information of the service data; the wireless access network device, core network device, and transmission devices in the bearer network (including the first transmission device) can measure the service data based on this unified flow identification information. Here, the unified network management device can be understood as a device that uniformly manages both the wireless network and the bearer network.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the measurement method information indicates a package-by-package measurement method or a sampling measurement method.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the measurement type information indicates at least one of packet loss rate measurement, packet loss count measurement, latency measurement, throughput measurement, or jitter measurement.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the control information and the service data are carried in user plane messages.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the control information is carried in the Internet Protocol (IP) extension header, User Datagram Protocol (UDP) extension header, or General Packet Radio Service User Plane Tunneling Protocol (GTPU) extension header of the user plane message. In this implementation, after receiving the user plane message, the first transmission device performs a snooping operation on the user plane message to obtain the control information.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the control information is carried in a control plane message, and the service data is carried in a user plane message. In this implementation, the control information and service data are sent to the first transmission device separately via different information / messages.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the control information is carried in the IP extension header, Transmission Control Protocol (TCP) extension header, UDP extension header, or GTPU extension header of the control plane message, and the destination address of the control plane message is the address information of the radio access network device or the core network device. In this implementation, after receiving the control plane message, the first transmission device performs a sniffing operation on the control plane message to obtain the control information.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the control plane message includes a GTPU ECHO message, an Internet Control Message Protocol (ICMP) message, a Two-Way Active Measurement Protocol (TWAMP) message, or a UDP message.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the control information is carried in the IP extension header or IP payload of the control plane message, and the destination address of the control plane message is the address information of the first transmission device. In this implementation, the radio access network device and the core network device do not send control information through extended existing messages, but rather through specific / newly constructed control plane messages. Since the destination address of the control plane message is the address information of the first transmission device, after receiving the control plane message, the first transmission device can directly parse the control plane message to obtain the control information.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the control plane message includes ICMP message, TCP message, UDP message, Flow Control Transfer Protocol (SCTP) message, or other IP message.

[0020] Secondly, a data measurement method is provided, which can be applied to a wireless access network device or a core network device. For example, it can be executed by the wireless access network device or the core network device, or it can be executed by a component (such as a chip, chip system, etc.) configured in the wireless access network device or the core network device, or it can be implemented by a logic module or software that can realize all or part of the functions of the wireless access network device or the core network device. This application does not limit this.

[0021] The method includes: sending control information and service data to a first transmission device, wherein the control information includes at least one of the following: flow identification information, measurement method information, measurement period information, or measurement type information of the service data, and the control information is used to control at least one transmission device in the bearer network to measure the service data, wherein the at least one transmission device includes the first transmission device; and sending second measurement result information to a second network management device, wherein the second measurement result information is obtained by measuring the service data according to the control information.

[0022] The method provided in the second aspect is the same as the method on the wireless access network device or core network device side corresponding to the first aspect, and its beneficial effects can be referred to the first aspect.

[0023] In conjunction with the second aspect, in some implementations of the second aspect, the measurement method information indicates a package-by-package measurement method or a sampling measurement method.

[0024] In conjunction with the second aspect, in some implementations of the second aspect, the measurement type information indicates at least one of packet loss rate measurement, packet loss count measurement, latency measurement, throughput measurement, or jitter measurement.

[0025] In conjunction with the second aspect, in some implementations of the second aspect, the control information and the service data are carried in user plane messages.

[0026] In conjunction with the second aspect, in some implementations of the second aspect, the control information is carried in the IP extension header, UDP extension header, or GTPU extension header of the user plane message.

[0027] In conjunction with the second aspect, in some implementations of the second aspect, the control information is carried in the control plane message, and the service data is carried in the user plane message.

[0028] In conjunction with the second aspect, in some implementations of the second aspect, the control information is carried in the IP extension header, TCP extension header, UDP extension header, or GTPU extension header of the control plane message, and the destination address of the control plane message is the address information of the wireless access network device or the core network device.

[0029] In conjunction with the second aspect, in some implementations of the second aspect, the control plane message includes GTPU ECHO message, ICMP message, TWAMP message, or UDP message.

[0030] In conjunction with the second aspect, in some implementations of the second aspect, the control information is carried in the IP extension header or IP packet payload of the control plane message, and the destination address of the control plane message is the address information of the first transmission device.

[0054] Radio access network (RAN) equipment provides services to cells. Terminal devices communicate with cells through transmission resources (e.g., frequency domain resources, or spectrum resources) allocated by the RAN equipment. These cells can belong to macro base stations (e.g., macro eNB or macro gNB) or to base stations corresponding to small cells. Small cells can include metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0057] Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction. Broadly defined, wearable smart devices include those with comprehensive functions, large sizes, and the ability to perform complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses. They also include devices focused on a specific application function that require the use of other devices, such as smart bracelets and smart jewelry for vital sign monitoring.

[0061] The AMF (Automatic Mobility Management) element is primarily responsible for mobility management in mobile networks, such as user location updates, user registration with the network, and user handover. The UPF (User Provider Function) element is primarily responsible for forwarding and receiving user data in terminal devices; the UPF element can receive user data from the data network and transmit it to the terminal device via the radio access network equipment; the UPF element can also receive user data from the terminal device via the radio access network equipment and forward it to the data network; the transmission resources and scheduling functions provided by the UPF element to the terminal device are managed and controlled by the SMF (Signal Management Function) element.

[0063] To facilitate understanding of the technical solutions of the embodiments of this application, before introducing the solutions of the embodiments of this application, the terms or concepts that may be involved in the embodiments of this application will be introduced first.

[0064] 1. Protocol Data Unit (PDU) Session: A logical connection between a terminal device and a data network (DN), used to provide the terminal device with a user plane connection to the DN.

[0065] 2. Bearer Network: The bearer network is the basic network that provides network connectivity for the wireless access network (wireless network) and the core network. It consists of access routers, edge routers, and core routers. In order to meet the needs of 5G application scenarios, the 5G bearer network is constantly evolving towards high bandwidth, low latency, network slicing, and intelligence, providing 5G networks with ultra-high bandwidth, ultra-low latency, and flexible and intelligent connection services.

[0066] To facilitate understanding of the embodiments of this application, the technical solutions related to the embodiments of this application will be briefly introduced below.

[0067] I. Wireless Network Measurement Technology

[0068] Figure 2 is a schematic flowchart of a QoS monitoring scheme in a wireless network. The specific process is as follows.

[0069] 1. Manually issue man-machine language (MML) commands in SMF to start slice monitoring; SMF adds MML configuration, which includes slice identifier (identy, ID), maximum number of sessions, and measurement start / measurement stop. Among them, slice ID indicates which services of which slices are to be measured, maximum number of sessions indicates the specifications of the measured services, measurement start indicates when to start measurement, and measurement stop indicates when to stop measurement.

[0070] 2. Manually start the key performance indicator (KPI) statistics of the call statistics in the element management system (EMS).

[0071] 3. SMF samples based on the number of users per slice. Latency monitoring is initiated upon session creation. Specifically, the response message sent by AMF to the base station upon session creation includes indication information to initiate latency monitoring. SMF needs to manage the latency monitoring task of Quality of Service (QoS) flow and needs to assess the impact of QoS flow latency on system memory.

[0072] Among them, the network slice subnet management function (NSSMF) on the core network (CN) distributes the maximum number of sessions per slice to the SMF, and the SMF needs to calculate the number of QoS flows according to the product's default traffic model.

[0073] 4. SMF controls UPF to enable latency monitoring. For example, when there are few slices, sampling can be fixed at 1%, while limiting the minimum number of users, such as limiting the number of users to no less than 10.

[0074] 5. Base station starts sampling air interface delay.

[0075] 6. The base station calculates the air interface delay between the base station and the terminal device, such as uplink delay X1 / downlink delay X2.

[0076] 7. The UPF starts sampling. The GTPU's message header carries a Quality of Service Monitoring Packet (QMP) tag. The UPF can sample at 1 message / 10ms. The sampling specification on the UPF can not exceed 1% of the QoS flow number specification.

[0077] 8. The base station reports latency statistics to the UPF;

[0078] 9. UPF calculates the round trip time (RTT) as follows: X1 + X2 + (t6 - t1) - (t5 - t2);

[0079] 10. The UPF generates the average latency, minimum latency, maximum latency, and number of statistics for base station-UPF / terminal equipment-UPF according to the statistical period of the call statistics (e.g., 5 minutes / 15 minutes), and reports the latency statistics results to EMS.

[0080] 11. EMS reports latency statistics to CN NSSMF, and CN NSSMF performs performance statistics and monitoring of slice-level latency KPIs.

[0081] II. Bearer Network Measurement Technology

[0082] Figure 3 is a schematic diagram of a flow measurement scheme in a bearer network. The flow measurement process for initiating a service flow in a bearer network includes:

[0083] 1. The ingress device initiates hop-by-hop flow detection of the service flow and periodically reports measurement data (measurement results information) such as packet loss rate, latency, and jitter to the network management device of the bearer network. The ingress device can be understood as the head node in the bearer network that connects to the wireless access network device. The network management device of the bearer network can be the network cloud engine (NCE).

[0084] 2. The intermediate (transit) device initiates hop-by-hop flow detection of the service flow and periodically reports measurement data such as packet loss rate, latency, and jitter to the network management device of the bearer network;

[0085] 3. The egress device initiates hop-by-hop flow detection of the service flow and periodically reports measurement data such as packet loss rate, latency, and jitter to the network management device of the bearer network;

[0086] 4. The network management equipment collects measurement data reported by the ingress, intermediate and egress devices in the bearer network, performs segmented calculations, and presents the packet loss rate, latency and jitter of each device (node) / link in the bearer network, which facilitates troubleshooting by operation and maintenance personnel.

[0087] Here, ETH stands for Ethernet, and MPLS LABEL refers to a multi-protocol label switching table. It should be noted that the entry device, intermediate device, and exit device in this application embodiment can be collectively referred to as transmission device, bearer device, bearer node, or gateway device, without limitation.

[0088] III. End-to-End Measurement Techniques for Wireless and Bearer Networks

[0089] Figure 4 is a schematic diagram of end-to-end transmission measurements on the wireless network and the bearer network. The specific process includes:

[0090] 1. The AMF controls the terminal equipment, base station and UPF to start QoS monitoring and uniformly reports the measurement data to the network management equipment of the wireless network. The network management equipment of the wireless network can be EMS.

[0091] 2. Wireless network maintenance personnel manually obtain the flow identifier information that needs to be measured and inform the bearer network maintenance personnel; the bearer network maintenance personnel manually input the flow identifier information and control the transmission equipment in the bearer network to start hop-by-hop flow detection of the service flow; the transmission equipment in the bearer network reports the measurement data to the network management device of the bearer network, wherein the network management device of the bearer network can be an NCE;

[0092] 3. If the flow identification information to be measured changes, repeat step 2.

[0093] Because the encapsulation formats and flow identifiers of service data in wireless networks and bearer networks are inconsistent, different networks cannot communicate with each other, thus making it impossible to achieve end-to-end automatic transmission measurement between wireless networks and bearer networks.

[0094] Therefore, this application proposes a data measurement method that enables automatic end-to-end (device-to-device) measurement on wireless networks and bearer networks.

[0095] Figure 5 is a schematic flowchart of a data measurement method 500 according to an embodiment of this application. In this embodiment, the first transmission device can be an ingress or egress device in a bearer network, the wireless access network device can be a base station, the core network device can be a UPF, and the terminal device can be a UE.

[0096] 510. A wireless access network device or a core network device sends control information and service data to a first transmission device. The control information includes at least one of the following: first flow identification information, measurement method information, measurement period information, or measurement type information of the service data. The first flow identification information is the flow identification information of the service data in the wireless network. Correspondingly, the first transmission device receives the control information and service data. The control information is used to control at least one transmission device in the bearer network to measure the service data. The at least one transmission device includes the first transmission device.

[0097] For example, a wireless access network device sends control information and service data to a first transmission device; correspondingly, the first transmission device receives control information and service data from the wireless access network device, where the first transmission device is an ingress device in the bearer network. This example represents the uplink transmission of service data.

[0098] For example, the core network device sends control information and service data to the first transmission device; correspondingly, the first transmission device receives control information and service data from the core network device, where the first transmission device is the egress device in the bearer network. This example represents downlink transmission of service data.

[0099] Optionally, the measurement method information indicates either package-by-package measurement or sampling measurement.

[0100] Optionally, the measurement type information indicates at least one of packet loss rate measurement, number of lost packets measurement, latency measurement, throughput measurement, or jitter measurement.

[0101] Optionally, control information and business data are carried in user plane messages.

[0102] In one implementation, control information is carried in the IP extension header, UDP extension header, or GTPU extension header of the user plane packet. In this implementation, after receiving the user plane packet, the first transmission device performs a snooping operation on the user plane packet to obtain the control information.

[0103] For example, taking the GTPU user plane service packet as an example, an IP extension header is added to the GTPU user plane service packet. Control information is carried in this new IP extension header, and the control information and service data are sent together to the first transmission device. Figure 6 is a schematic diagram of adding an IP extension header to the GTPU user plane service packet. The left side corresponds to the IPv4 header format, and the right side corresponds to the IPv6 header format. IHL represents the Internet header length.

[0104] For example, taking the GTPU user plane service message as an example, a UDP extension header is added to the GTPU user plane service message. Control information is carried in this new UDP extension header, and the control information and service data are sent together to the first transmission device. Figure 7 is a schematic diagram of adding a UDP extension header to the GTPU user plane service message; specifically, a magic number (probe marker) and a UDP extended measurement header are added after the UDP header.

[0105] Optionally, control information is carried in control plane messages, and service data is carried in user plane messages. In this optional scheme, control information and service data are sent to the first transmission device separately using different information / messages.

[0106] In one implementation, control information is carried in the IP extension header, Transmission Control Protocol (TCP) extension header, UDP extension header, or GTPU extension header of the control plane message. The destination address of the control plane message is the address information of the radio access network device or the core network device. Specifically, when the first transmission device is an ingress device / uplink transmission in the bearer network, the destination address of the control plane message is the address information of the core network device; when the first transmission device is an egress device / downlink transmission in the bearer network, the destination address of the control plane message is the address information of the radio access network device. In this implementation, after receiving the control plane message, the first transmission device performs a sniffing operation on the control plane message to obtain the control information.

[0107] For example, control plane messages include GTPU ECHO messages, Internet Control Message Protocol (ICMP) messages, Two-Way Active Measurement Protocol (TWAMP) messages, or UDP messages. Control plane messages may also include other existing control plane messages, which are not limited in this application.

[0108] For example, taking the GTPU ECHO control plane message as an example, a GTPU extension header is added to the GTPU ECHO message, and the control information is carried in this newly added GTPU extension header. Figure 8 is a schematic diagram of adding a GTPU extension header to the GTPU ECHO message.

[0109] In one implementation, control information is carried in the IP extension header or IP payload of the control plane message, and the destination address of the control plane message is the address information of the first transmission device. In this implementation, the radio access network device and the core network device do not send control information through extended existing messages, but rather through specific / newly constructed control plane messages. Since the destination address of the control plane message is the address information of the first transmission device, the first transmission device can directly parse the control plane message upon receiving it to obtain the control information.

[0110] For example, control plane messages include ICMP messages, TCP messages, UDP messages, or Stream Control Transmission Protocol (SCTP) messages, or other IP messages. For instance, if the control plane message is an IP message, the control information can be carried in an IP header or IP payload. Control plane messages can also be any other specific or newly constructed control plane message; this application does not limit the specific type of control plane message.

[0111] Optionally, before the radio access network (RAN) device or core network device sends control information and service data to the first transmission device, the AMF controls the terminal devices, RAN devices, and core network devices in the wireless network to initiate QoS monitoring and uniformly reports their respective measurement results to the core network device. The flow identification information of the service data in the wireless network may include one or more of the following: tunnel endpoint identifier (TEID), QoS flow identifier, service data flow protocol type, protocol port number of the RAN device, protocol port number of the core network device, IP address of the RAN device, IP address of the core network device, or IPv6 flow label of the RAN device.

[0112] 520. The first transmission device measures the service data according to the control information to obtain first measurement result information. For example, the first transmission device performs in-situ flow information telemetry (iFiT), in-band operation administration and maintenance (IOAM), or other flow measurement methods on the service data according to the control information to obtain the first measurement result information.

[0113] Optionally, before the first transmission device measures the service data according to the control information, the first transmission device converts the first flow identification information into the second flow identification information and saves the mapping relationship between the first flow identification information and the second flow identification information. The second flow identification information is the flow identification information of the service data in the bearer network. The first measurement result information includes the mapping relationship between the first flow identification information and the second flow identification information.

[0114] Optionally, the unified network management device can assign unified flow identification information, ensuring that the flow identification information for service data is the same in both the wireless network and the bearer network. In this optional scheme, the first transmission device does not need to convert the flow identification information of the service data; the wireless access network device, core network device, and transmission devices in the bearer network (including the first transmission device) can measure the service data based on this unified flow identification information. Here, the unified network management device can be understood as a device that uniformly manages both the wireless network and the bearer network.

[0115] 530, the first transmission device sends the first measurement result information to the first network management device; correspondingly, the first network management device receives the first measurement result information.

[0116] It should be noted that the transmission devices in the bearer network will measure the service data according to the control information and send their respective first measurement result information to the first network management device; the first network management device receives the first measurement result information corresponding to each transmission device.

[0117] 540. The wireless access network device and the core network device respectively send second measurement result information to the second network management device. The second measurement result information is obtained by measuring service data according to control information. For example, the wireless access network device measures service data according to control information, obtains the second measurement result information, and sends the second measurement result information to the second network management device. The core network device measures service data according to control information, obtains the second measurement result information, and sends the second measurement result information to the second network management device. Correspondingly, the second network management device receives the second measurement result information sent by the wireless access network device and the core network device in the wireless network. In this embodiment, the network management device of the wireless network can be collectively referred to as the second network management device. For example, the network management device of the wireless access network device and the network management device of the core network device can be collectively referred to as the second network management device.

[0118] Optionally, the terminal device measures the service data according to the control information, obtains the second measurement result information, and sends the second measurement result information obtained by the terminal device to the radio access network device. The radio access network device can directly report the second measurement result information obtained by the terminal device to the network management device of the radio access network device, or the radio access network device can report the second measurement result information obtained by the terminal device to the core network device, and the core network device will then report it to the network management device of the core network device.

[0119] Step 540 can be executed before step 510, and step 540 can be executed at any time between the execution of step 510 and step 530. This application embodiment does not limit this.

[0120] In the technical solution provided in this application embodiment, the wireless access network device or core network device in the wireless network can send control information for measuring service data to the transmission device (first transmission device) in the bearer network. The transmission device in the bearer network can automatically measure the service data from the wireless network based on the control information. Compared with the transmission measurement scheme in which wireless network maintenance personnel and bearer network maintenance personnel manually input flow identification information, this application can realize end-to-end (device-to-device) automatic measurement between the wireless network and the bearer network.

[0121] Optionally, the first network management device is a network management device for the bearer network, such as an NCE; the second network management device is a network management device for the wireless network, such as an EMS. Optionally, the first network management device sends first measurement result information to a unified network management device, and the second network management device sends second measurement result information to the unified network management device; correspondingly, the unified network management device receives the first and second measurement result information, and determines at least one of the following: packet loss rate, latency, throughput, or jitter of the service data on the transmission path, based on the first and second measurement result information. The transmission path of the service data includes: terminal device → wireless access network device → transmission device in the bearer network (e.g., the first transmission device) → core network device, or, core network device → transmission device in the bearer network (e.g., the first transmission device) → wireless access network device → terminal device.

[0122] Optionally, the first network management device and the second network management device are the same network management device. For example, the first network management device is the aforementioned unified network management device, which determines at least one of the following: packet loss rate, latency, throughput, or jitter of the service data on the transmission path, based on the first measurement result information and the second measurement result information.

[0123] The data measurement method provided in this application embodiment is described below with specific examples. In this example, the transmission path of service data is taken as follows: terminal device → wireless access network device → transmission device (e.g., first transmission device) in the bearer network → core network device.

[0124] Step 1: The AMF controls the terminal devices, wireless access network devices, and core network devices in the wireless network to start QoS monitoring and uniformly report their measurement results to the core network device.

[0125] Step 2: The wireless access network device in the wireless network initiates the measurement of service data with the first flow identification information and obtains the second measurement result information; wherein, the wireless access network device measures the service data in a packet-by-packet measurement mode or a sampling measurement mode, and the measured parameter or type is at least one of packet loss rate, latency, throughput, or jitter, and the measurement period is T.

[0126] It should be noted that terminal devices and core network devices in the wireless network will also initiate measurements of service data with flow identification information as first flow identification information, and obtain their respective second measurement result information.

[0127] Step 3: The wireless access network device sends control information and service data to the first transmission device in the bearer network. The control information includes first-stream identification information, measurement method information, measurement period information, and measurement type information of the service data. The measurement method information indicates a packet-by-packet measurement method or a sampling measurement method. The measurement period information indicates a measurement period of T. The measurement type information indicates at least one of packet loss rate measurement, packet loss count measurement, latency measurement, throughput measurement, or jitter measurement. The first transmission device is the entry device in the bearer network. Correspondingly, the first transmission device receives the control information and service data from the wireless access network device.

[0128] Step 4: The first transmission device converts the first flow identification information into the second flow identification information and saves the mapping relationship between the first flow identification information and the second flow identification information. The second flow identification information is the flow identification information of the service data in the bearer network.

[0129] Step 5: The first transmission device measures the service data according to the control information to obtain first measurement result information. For example, the first transmission device performs flow detection, IOAM, or other flow measurement on the service data according to the control information to obtain the first measurement result information. The first measurement result information includes the mapping relationship between first flow identifier information and second flow identifier information.

[0130] It should be noted that the transmission equipment in the bearer network will measure the service data according to the control information and obtain the first measurement result information of each device.

[0131] Step Six: The transmission devices in the bearer network send their respective first measurement result information to the first network management device. Correspondingly, the first network management device receives the first measurement result information. The first network management device is the network management device of the bearer network, for example, the first network management device is the NCE (Network Entity). The wireless access network devices and core network devices in the wireless network send their respective second measurement result information to the second network management device. Correspondingly, the second network management device receives the second measurement result information. The network management devices of the wireless network can be collectively referred to as the second network management device. For example, the network management devices of the wireless access network devices and the core network devices can be collectively referred to as the second network management device.

[0132] Optionally, the terminal device measures the service data according to the control information, obtains the second measurement result information, and sends the second measurement result information obtained by the terminal device to the radio access network device. The radio access network device can directly report the second measurement result information obtained by the terminal device to the network management device of the radio access network device, or the radio access network device can report the second measurement result information obtained by the terminal device to the core network device, and the core network device will then report it to the network management device of the core network device.

[0133] Step 7: The first network management device sends the first measurement result information to the unified network management device (or third-party service device), and the second network management device sends the second measurement result information to the unified network management device (or third-party service device). The unified network management device (or third-party service device) can be understood as a device that uniformly manages both the wireless network and the network carrying the network. Correspondingly, the unified network management device receives the first measurement result information from the first network management device and the second measurement result information from the second network management device.

[0134] Step 8: The unified network management device (or third-party service device) determines at least one of the following: packet loss rate, latency, throughput, or jitter of the service data on the transmission path, based on the first measurement result information and the second measurement result information.
