Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a method and device for data measurement. Background Art

[0002] In the quality of service (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 start of flow measurement. After the communication equipment in the wireless network measures the service data, it reports the measurement result information obtained by the measurement to the network management equipment of the wireless network, and the network management equipment of the wireless network determines the QoS of the wireless network based on the measurement result information. In the QoS monitoring of the bearer network, the bearer network maintenance personnel also need to manually obtain the flow identification information of the service data to be measured, and manually control the start of flow measurement. After the communication equipment in the bearer network measures the service data, it reports the measurement result information obtained by the measurement to the network management equipment of the bearer network, and the network management equipment of the bearer network determines the QoS of the bearer network based on the measurement result information.

[0003] When the transmission of business data needs to pass through the wireless network and the bearer network, due to the inconsistent encapsulation format and flow identifier definition of the business data in the wireless network and the bearer network, different networks cannot communicate with each other, so it is impossible to achieve end-to-end (device-to-device) automatic transmission measurement on the wireless network and the bearer network. Summary of the invention

[0004] The present application provides a method and apparatus for data measurement, which can realize end-to-end (device-to-device) automatic measurement on a wireless network and a bearer network.

[0005] In the first aspect, a method for data measurement is provided, which can be applied to a first transmission device in a bearer network. For example, it can be executed by the first transmission device, or it can be executed by a component configured in the first transmission device (such as a chip, a chip system, etc.), or it can be implemented by a logic module or software that can implement all or part of the functions of the first transmission device. The present application does not limit this.

[0007] 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, and 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 solution in which the wireless network maintenance personnel and the bearer network maintenance personnel manually input the flow identification information, the present application can realize end-to-end (device-to-device) automatic measurement on the wireless network and the bearer network.

[0009] Optionally, a unified network management device can allocate unified flow identification information, and the flow identification information of the service data in the wireless network and the bearer network is the same. In this optional solution, the first transmission device does not need to convert the flow identification information of the service data, and the wireless access network device, the core network device and the transmission device in the bearer network (including the first transmission device) can measure the service data based on the unified flow identification information. Among them, the unified network management device can be understood as a device that uniformly manages the network management device of the wireless network and the network management device of the bearer network.

[0062] In order to facilitate understanding of the technical solutions of the embodiments of the present application, before introducing the solutions of the embodiments of the present application, the terms or concepts that may be involved in the embodiments of the present application are first introduced.

[0063] 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.

[0064] 2. Bearer network: The bearer network is the basic network that provides network connections 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 continues to evolve in the direction of large bandwidth, low latency, network slicing, and intelligence, providing 5G networks with ultra-large bandwidth, ultra-low latency, flexible and intelligent connection services.

[0065] In order to facilitate the understanding of the embodiments of the present application, the technical solutions related to the embodiments of the present application are briefly introduced below.

[0066] 1. Wireless Network Measurement Technology

[0067] Figure 2 It is a schematic flow chart of a QoS monitoring solution in a wireless network, and the specific process is as follows.

[0068] 1. Manually send a man-machine language (MML) command in SMF to start slice monitoring; SMF adds an MML configuration, which includes a slice identifier (ID), a maximum number of sessions, and measurement start / measurement stop, wherein the slice ID indicates which services of which slices are measured, the maximum number of sessions indicates the specifications of the measured services, the measurement start indicates when to start the measurement, and the measurement stop indicates when to stop the measurement.

[0069] 2. Manually start the key performance indicator (KPI) statistics of the call statistics in the element management system (EMS).

[0070] 3. SMF samples according to the number of users in the slice and starts delay monitoring when the session is created. Specifically, the response message sent by AMF to the base station when the session is created includes indication information for instructing to start delay monitoring. SMF needs to manage the delay monitoring task of the quality of service flow (QoS flow) and needs to evaluate the impact of the delay of the QoS flow on the system memory.

[0071] Among them, the network slice subnet management function (NSSMF) on the core network (CN) sends the maximum number of sessions of the slice to SMF, and SMF needs to calculate the number of QoS flows according to the product's default traffic model.

[0072] 4. SMF controls UPF to start latency monitoring. For example, when there are fewer slices, sampling can be fixed at 1%, and the minimum number of users can be limited. For example, the number of users cannot be less than 10.

[0073] 5. The base station starts sampling the air interface delay.

[0074] 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.

[0075] 7. UPF starts sampling. The GTPU packet header carries a QoS monitoring packet (QMP) tag. UPF can sample at 1 packet / 10ms. The sampling specification controlled by UPF cannot exceed 1% of the QoS flow number specification.

[0076] 8. The base station reports delay statistics to the UPF;

[0077] 9. UPF calculates round trip time (RTT) = X1 + X2 + (t6 - t1) - (t5 - t2);

[0078] 10. UPF generates the average delay, minimum delay, maximum delay and statistical times of base station-UPF / terminal equipment-UPF according to the statistical period of the call statistics (for example, 5 minutes / 15 minutes), and reports the delay statistical results to EMS.

[0079] 11. EMS reports latency statistics to CN NSSMF, and CN NSSMF implements performance statistics and monitoring of slice-level latency KPI.

[0080] 2. Bearer Network Measurement Technology

[0081] Figure 3 The following is a schematic diagram of a flow measurement solution in a bearer network. The flow measurement process of a bearer network starting a service flow includes:

[0082] 1. The ingress device starts hop-by-hop flow detection of the service flow and periodically reports the measurement data (measurement result information) such as packet loss rate, delay, and jitter to the network management device of the bearer network. The ingress device is understood as the head node connected to the wireless access network device in the bearer network, and the network management device of the bearer network can be a network cloud engine (NCE);

[0083] 2. The transit device starts hop-by-hop flow detection of the service flow and periodically reports the measurement data such as packet loss rate, delay, and jitter to the network management device of the bearer network;

[0084] 3. The egress device starts hop-by-hop flow detection of the service flow and periodically reports measurement data such as packet loss rate, delay, and jitter to the network management device of the bearer network;

[0085] 4. The network management equipment collects the measurement data reported by the ingress equipment, intermediate equipment and egress equipment in the bearer network, and performs segmented calculations to present the packet loss rate, delay, and jitter of each device (node) / link in the bearer network, which is convenient for operation and maintenance personnel to troubleshoot.

[0086] Among them, ETH refers to Ethernet, and MPLS LABEL refers to multi-protocol label switching. It should be noted that the ingress device, intermediate device and egress device in the embodiments of the present application can be collectively referred to as transmission equipment, bearer equipment, bearer node or gateway equipment, without limitation.

[0087] 3. End-to-end measurement technology on wireless networks and bearer networks

[0088] Figure 4 This is a schematic diagram of end-to-end transmission measurement on wireless networks and bearer networks. The specific process includes:

[0089] 1. AMF controls the terminal equipment, base station and UPF to start QoS monitoring, and uniformly reports the measurement data to the network management device of the wireless network, where the network management device of the wireless network can be EMS;

[0090] 2. The wireless network maintenance personnel manually obtains the flow identification information to be measured and informs the bearer network maintenance personnel; the bearer network maintenance personnel manually inputs the flow identification information and controls 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 equipment of the bearer network, where the network management equipment of the bearer network may be NCE;

[0091] 3. If the flow identification information to be measured changes, repeat step 2.

[0092] Since the encapsulation format and flow identifier definition of the service data in the wireless network and the bearer network are inconsistent, different networks cannot communicate with each other, so it is impossible to implement end-to-end automatic transmission measurement on the wireless network and the bearer network.

[0093] To this end, an embodiment of the present application proposes a method for data measurement, which can implement end-to-end (device-to-device) automatic measurement on a wireless network and a bearer network.

[0094] Figure 5 The schematic flow chart of a data measurement method 500 of an embodiment of the present application is as follows. The first transmission device in the embodiment of the present application may be an ingress device or an egress device in a bearer network, the wireless access network device may be a base station, the core network device may be a UPF, and the terminal device may be a UE.

[0095] 510, a wireless access network device or a core network device sends control information and service data to a first transmission device, where the control information includes at least one of first flow identification information, measurement mode information, measurement period information, or measurement type information of the service data, and the first flow identification information is flow identification information of the service data in the wireless network; correspondingly, the first transmission device receives the control information and the service data. The control information is used to control at least one transmission device in the bearer network to measure the service data, and the at least one transmission device includes the first transmission device.

[0096] Exemplarily, the wireless access 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 wireless access network device, and the first transmission device is an ingress device in the bearer network. This example is an uplink transmission of service data.

[0097] Exemplarily, 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, and the first transmission device is an egress device in the bearer network. This example is downlink transmission of service data.

[0098] Optionally, the measurement mode information indicates a packet-by-packet measurement mode or a sampling measurement mode.

[0099] Optionally, the measurement type information indicates at least one of packet loss rate measurement, packet loss number measurement, delay measurement, throughput measurement, or jitter measurement.

[0100] Optionally, the control information and service data are carried in a user plane message.

[0101] In one implementation, the control information is carried in an IP extension header, a UDP extension header, or a GTPU extension header of a 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.

[0102] For example, taking the user plane message as a GTPU user plane service message, a new IP extension header is added to the GTPU user plane service message, control information is carried in the newly added IP extension header, and the control information is sent to the first transmission device together with the service data. Figure 6 This is a schematic diagram of adding an IP extension header to a GTPU user plane service message. The left side corresponds to the IPv4 header format, and the right side corresponds to the IPv6 header format, where IHL stands for internet header length.

[0103] For another example, taking the user plane message as a GTPU user plane service message, a new UDP extension header is added to the GTPU user plane service message, control information is carried in the newly added UDP extension header, and the control information is sent to the first transmission device together with the service data. Figure 7 This is a schematic diagram of adding a UDP extension header to a GTPU user plane service message; specifically, a magic number (probe marker) and a UDP extension measurement header are added after the UDP header.

[0104] Optionally, the control information is carried in a control plane message, and the service data is carried in a user plane message. In this optional solution, the control information and the service data are respectively sent to the first transmission device via different information / messages.

[0105] In one implementation, the control information is carried in an IP extension header, a transmission control protocol (TCP) extension header, a UDP extension header, or a GTPU extension header of a control plane message, and the destination address of the control plane message is the address information of a wireless access network device or a core network device. Specifically, when the first transmission device is an ingress device / uplink transmission in a bearer network, the destination address of the control plane message is the address information of a core network device; when the first transmission device is an egress device / downlink transmission in a bearer network, the destination address of the control plane message is the address information of a wireless 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.

[0106] Exemplarily, 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. The control plane message may also include other existing control plane messages, which are not limited in this application.

[0107] For example, taking the control plane message as a GTPU ECHO message as an example, a GTPU extension header is added to the GTPU ECHO message, and the control information is carried in the newly added GTPU extension header. Figure 8 This is a schematic diagram of adding a GTPU extension header to a GTPU ECHO message.

[0108] In one implementation, the control information is carried in an IP extension header or an IP message payload of a 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 wireless access network device and the core network device do not send the control information through the extended existing message, but send the control information through a specific / newly constructed control plane message. 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.

[0109] Exemplarily, the control plane message includes an ICMP message, a TCP message, a UDP message, or a stream control transmission protocol (SCTP) message, or other IP messages. For example, if the control plane message is an IP message, the control information can be carried in an IP extension header or an IP message payload. The control plane message can also be any other specific or newly constructed control plane message, which is not limited in this application.

[0110] Optionally, before the wireless access network device or the core network device sends control information and service data to the first transmission device, the AMF controls the terminal device, the wireless access network device and the core network device in the wireless network to start QoS monitoring, and uniformly reports the respective measurement result information to the core network device. The flow identification information of the service data in the wireless network may include: a tunnel endpoint identifier (TEID), a QoS flow identifier (QoS flow identifier), a flow protocol type of the service data, a protocol port number of the wireless access network device, a protocol port number of the core network device, an IP of the wireless access network device, an IP of the core network device, or an IPv6 flow label (flow lable) of the wireless access network device or more.

[0111] 520. The first transmission device measures the service data according to the control information to obtain first measurement result information. Exemplarily, the first transmission device performs in-situ flow information telemetry (iFiT) or in-band operation administration and maintenance (IOAM) or other flow measurement on the service data according to the control information to obtain the first measurement result information.

[0112] 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, where 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.

[0113] Optionally, a unified network management device can allocate unified flow identification information, and the flow identification information of the service data in the wireless network and the bearer network is the same. In this optional solution, the first transmission device does not need to convert the flow identification information of the service data, and the wireless access network device, the core network device and the transmission device in the bearer network (including the first transmission device) can measure the service data based on the unified flow identification information. Among them, the unified network management device can be understood as a device that uniformly manages the network management device of the wireless network and the network management device of the bearer network.

[0114] 530. The first transmission device sends first measurement result information to the first network management device. Correspondingly, the first network management device receives the first measurement result information.

[0115] It should be noted that the transmission equipment in the bearer network measures the service data according to the control information and sends respective first measurement result information to the first network management equipment; the first network management equipment receives the first measurement result information respectively corresponding to the transmission equipment.

[0116] 540, the wireless access network device and the core network device respectively send second measurement result information to the second network management device, and the second measurement result information is obtained by measuring the service data according to the control information. Exemplarily, the wireless access network device measures the service data according to the 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 the service data according to the 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 respectively. In an embodiment of the present application, the network management devices of the wireless network can be collectively referred to as the second network management devices. For example, the network management devices of the wireless access network devices and the network management devices of the core network devices can be collectively referred to as the second network management devices.

[0118] Among them, step 540 can be executed before step 510, and step 540 can be executed at any time between step 510 and step 530, which is not limited in the embodiment of the present application.

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 a unified network management device; correspondingly, the unified network management device receives the first measurement result information and the second measurement result information, and determines at least one of the packet loss rate, delay, throughput, or jitter of the service data on the transmission path according to the first measurement result information and the second measurement result information.

Exemplarily, the first transmission device performs flow detection or 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 a mapping relationship between the first flow identification information and the second flow identification information.
