QoS information is an indicator to measure network performance. For example, QoS information may include at least one of delay information, packet loss rate, bandwidth, and jitter. Different services (for example, Internet browsing, voice and online games, etc.) have different requirements for QoS information. How to measure QoS information is a problem that needs to be solved. In the embodiments of this application, the delay information is used as an example to describe QoS information. However, the embodiments of the present application are not limited to this.

In the prior art, when the terminal device needs to measure the QoS information of a business data packet, a third-party application server can be used for detection, for example, the terminal device initiates the establishment of a protocol data unit (PDU) session to the core network. Request to establish a user plane connection between the terminal device and the third-party application server. After the user plane connection is established, the terminal device transmits data packets with the third-party application server through the user plane function network element to measure the terminal device and the third party application server. QoS information of data packets between three-party application servers. Taking the measurement delay as an example, for example, the terminal device records the time when the uplink data packet is sent to the user plane function network element as T1. After the user plane function network element sends the uplink data message to the application server, the application server The user plane function network element sends a downlink data message to the terminal device, and the terminal device records that the time for receiving the downlink data message is T2. Then the terminal device can calculate the round trip delay of the data message as T2-T1. The transmission delay of the downlink is symmetrical, and the transmission delay of the data packet in the uplink and downlink can be estimated as (T2-T1)/2. However, the above method of measuring QoS information cannot measure whether the QoS information of the link between the terminal device and the user plane functional network element truly meets the user's expectations. Therefore, how to measure the service between the terminal device and the user plane functional network element The QoS information of data is a problem to be solved by the embodiment of the present application. For another example, taking the measurement of network speed as an example, when users are not satisfied with the current network speed, they can apply for a traffic acceleration package, such as China Mobile's "I-Use" traffic acceleration service. The traffic acceleration service is indicated in the original Speed up on the basis of broadband, the cost is 15 yuan a month, for example, the original network speed is 2 megabits/second, after participating in this speedup, the network speed will mention 4 megabits/second -8 megabits/second. As shown in Figure 2, it is assumed that the third-party application server is measuring the network speed. The third-party application server measures the network speed between the terminal device and the third-party application server. However, after using the traffic acceleration package service to increase the speed, the improvement is The network speed between the terminal device and the core network element, but the third-party application server measures the network speed between the terminal device and the third-party application server, lacking to measure the QoS between the terminal device and the user plane function network element Information method. Therefore, after applying for the traffic acceleration package, the third-party application server cannot accurately determine whether the network speed between the terminal device and the user plane functional network element has reached the expected value. In other words, the user spends money to purchase the traffic acceleration service. Afterwards, whether the money spent by the user really meets the expected value cannot be accurately measured by the third-party application server, so it is impossible to determine whether the current network environment is suitable for initiating business data and reduce the user experience.

The embodiment of the present application provides a method for measuring QoS information. The terminal device can request measurement between the terminal device and the user plane functional network element in the current network environment through an application program interface at any time before initiating service data. QoS information of business data. For example, when the terminal device is located in a geographical location with a poor network environment, such as a subway station, a railway station, and other areas where people flow is concentrated, the terminal device can request to measure the actual QoS information of a service in the network environment to know that the current network environment cannot To meet user needs, the terminal device can choose a geographical location with a better network environment, such as an office park, to initiate data packet transmission of the service to obtain a better user experience. Therefore, the actual QoS information of the current network environment can be measured at any time before the service data is initiated, so that the terminal device can selectively perform services in a network environment with good actual QoS information, thereby improving the user experience.

The method for measuring service quality information in the embodiments of the present application is described below with reference to the drawings.

FIG. 3 shows a method for measuring service quality information provided by an embodiment of the present application, including:

S310. Before initiating service data, the terminal device sends a first message to the core network element through an application programming interface (API). The first message is used to request measurement of service data between the terminal device and the user plane function network element. Quality of service QoS information.

The embodiment of the present application does not limit the core network element. For example, the core network element may be the NEF element in FIG. 1. Before initiating service data, the terminal device sends the first message to the NEF through the application program interface. The first message is transparently transmitted to the PCF.

Optionally, the QoS information includes delay information.

Optionally, the first message includes at least one of a network protocol (IP) address of the terminal device, a service type identifier of the service data, an application identifier associated with the service data, or configuration parameters. The configuration parameter includes at least one of the size of the detection message, the frequency of sending the detection message, or the duration of sending the detection message.

When the first message includes the IP address of the terminal device, the policy control function network element may determine the terminal device that sends the first message according to the IP address of the terminal device. That is, the IP address of the terminal device is used to determine the terminal device that sent the first message.

When the first message includes the service type identifier of the service data, the policy control function network element may determine the service type that needs to perform QoS information measurement according to the service type identifier of the service data. That is to say, the service type identifier of the service data is used to determine the service type that needs to perform QoS information measurement.

When the first message includes the application identifier associated with the service data, the policy control function network element may determine the application requiring QoS information according to the application identifier associated with the service data. In other words, the application identifier associated with the business data is used to determine the application that needs QoS information.

When the first message includes configuration parameters, the user plane function network element may generate a detection message according to the configuration parameters. That is, the configuration parameters are used to detect the generation of messages. For example, after receiving the first message transparently transmitted by NEF, the PCF sends the configuration parameters in the first message to the user plane function network element through SMF, so that the user plane function network element can send a detection according to the size of the detection message. One or more of the frequency of the message and the duration of sending the detection message generates a detection message, so that the detection message is used to detect QoS information of service data between the terminal device and the user plane functional network element.

S320. The terminal device receives the second message sent by the core network element through the application program interface. The second message is used to trigger measurement of QoS information, or the second message includes QoS information.

In the embodiment of the present application, the QoS information may be measured by the terminal device, or the QoS information may be measured by the user plane network element. In the example in which the terminal device measures QoS information, the second message is used to trigger the measurement of QoS information. In the example where the user plane functional network element measures QoS information, the second message includes the QoS information measured by the user plane functional network element. For example, the second message may be a response message of the first message.

Therefore, in the embodiment of the present application, before initiating service data, the terminal device may send a first message requesting measurement of QoS information to the core network element (for example, NEF network element) through the application program interface, the core network element After sending the parameters in the first message to the user plane functional network element through PCF and SMF, the user plane functional network element can measure QoS information based on the parameters in the first message, and apply the QoS information to the terminal device through the second message Program interface sending. Alternatively, the core network element may send a second message to the application program interface of the terminal device to trigger the terminal device to measure QoS information. The QoS information in the embodiment of the present application is the QoS information of the service data to be initiated measured before the service data is initiated, and the QoS information between the terminal device and the user plane functional network element is measured, thereby improving the measurement of QoS information Accuracy helps to improve user experience. For example, when the terminal device is located in a geographical location with a poor network environment, such as a subway station, a railway station, and other areas where people flow is concentrated, the terminal device can request to measure the actual QoS information of a service in the network environment to know that the current network environment cannot To meet user needs, the terminal device can choose a geographic location with a better network environment, such as an office park, and then initiate data packet transmission of the service to obtain a better user experience. Therefore, the actual QoS information of the current network environment can be measured at any time before the service data is initiated, so that the terminal device can selectively perform services in a network environment with good actual QoS information, thereby improving the user experience.

The method for measuring service quality information in the embodiments of the present application is described below in two cases. The first case is that the terminal equipment measures QoS information. The second case is that the user plane functional network element measures QoS information. In the second case, after the user plane functional network element measures the QoS information, the QoS information may be sent to the terminal device through other network elements of the core network. For example, the user plane function network element can send the measured QoS information to the policy control function network element through the session management function network element, and the policy control function network element can send the QoS information to the NEF through the second message, and the NEF sends the second message Application program interface to terminal equipment.

In the first case, the second message is used to trigger the measurement of QoS information. For example, the QoS information is delay information. After the terminal device receives the second message sent by the core network element through the application program interface, the method further includes:

Optionally, the first detection message and the second detection message have the same configuration parameters, for example, the first detection message and the second detection message have the same size, and the first detection message and the second detection message The transmission frequency is the same, and the duration of the first detection message and the second detection message are the same.

Optionally, the first detection message and the second detection message have the same service type as the service data. Therefore, the delay information determined according to the first time and the second time is the same as the delay information of the service data. That is to say, before the service data is initiated, the delay information of the service data after initiation can be accurately measured and obtained.

Optionally, the source address of the first detection message is the IP address of the terminal device, the destination address of the first detection message is the IP address of the user plane functional network element, and the source address of the second detection message is the user plane functional network Yuan IP address, the destination address of the second detection message is the IP address of the terminal device.

Optionally, before generating the first detection message, the terminal device needs to obtain the IP address of the user plane functional network element. In a possible implementation manner, the second message includes the IP address of the user plane functional network element, and the terminal device may obtain the IP address of the user plane functional network element in the second message. For example, the SMF may send the IP address of the user plane function network element to the NEF through the PCF, and the NEF sends a second message containing the IP address of the user plane function network element to the application program interface of the terminal device. For another example, SMF may directly send the IP address of the user plane function network element to NEF, and NEF sends a second message containing the IP address of the user plane function network element to the application program interface of the terminal device, or NEF sends a message to the terminal device. After the application program interface sends the second message, the IP address of the user plane functional network element is sent to the application program interface of the terminal device through the third message.

That is, in the first case, when the terminal device sends the first message to the core network element, the first message may carry configuration parameters. For example, the core network element may be NEF. When the NEF receives the first message, it The first message is sent to the PCF, and then the PCF sends the configuration parameters in the first message to the UPF through SMF, so that the UPF can generate a second detection message according to the configuration parameters, thereby sending the second detection message to the terminal device. The terminal device may determine the delay information according to the time when the first detection message is sent (first time) and the time when the second detection message is received (second time), and the delay information is the terminal device and the user plane function network element Delay information between the detection packets. For example, if the first time is and the second time is, the terminal device can determine the round-trip delay information of the detection packet as t2-t1. Assuming that the uplink and downlink are symmetric, then the uplink and downlink delay information of the detection packet is Of course, the way to determine the delay information is not limited to this.

In the first case, the terminal device may determine the QoS information of the service data between the terminal device and the user plane function network element according to the time when the first detection message is sent and the time when the second detection message is received. It is determined by the terminal device itself, which can improve the trust degree of the terminal device in the QoS information.

Optionally, in the first case, the terminal device may send the determined QoS information to the capability open network element through the application program interface, and the capability open network element sends the QoS information to the policy control function network element to facilitate the policy control function The network element determines whether to adjust the QoS information of the business data.

The following describes the first case with reference to FIG. 4 using QoS information as delay information as an example. The method 400 includes:

S401. The capability opening network element receives a first message sent by a terminal device through an application program interface. The first message is used to request measurement of service quality QoS information of service data between the terminal device and a user plane functional network element.

S403. The network element of the policy control function determines a first forwarding rule based on the first message. The first forwarding rule and the forwarding rule of the service data include the same QoS information.

It should be noted that, in S403, the policy control function network element determines the first forwarding rule based on the first message, see description in method 600.

S404: The network element of the policy control function sends the first forwarding rule to the network element of the session management function, and the network element of the session management function receives the first forwarding rule sent by the network element of the policy control function.

S405: The network element of the session management function sends the first forwarding rule to the user plane function network element.

S406: The network element of the session management function sends the IP address of the user plane function network element to the policy control function network element.

Optionally, the order of S405 and S406 is not limited, and S405 may be before or after S406.

S407: The policy control function network element sends a second message to the capability opening network element, and the capability opening network element receives the second message, and the second message includes the IP address of the user plane function network element.

S408: The capability opening network element sends a second message to the terminal device, and the terminal device receives the second message sent by the capability opening network element.

S409. The terminal device obtains the IP address of the user plane functional network element in the second message, and generates a detection message 1 according to the IP address of the user plane function network element. The source address of the detection message 1 is the IP address of the terminal device. The destination address of Article 1 is the IP address of the user plane functional network element.

The source address of the detection message 2 is the IP address of the user plane functional network element, and the destination address of the detection message is the IP address of the terminal device.

The detection packet 2 and the detection packet 1 have the same configuration parameters. For example, the detection packet 2 and the detection packet 1 have the same size, the same transmission frequency, and the same duration.

Optionally, before S411, the user plane functional network element may obtain the IP address of the terminal device according to the following two ways:

In the first method, the terminal device determines the data network name (DNN) and single network slicing auxiliary information (single network) associated with the application based on locally stored user routing policy (UESP) information. slice selection (information, S-NSSAI), and then the UE sends a session establishment request to the AMF through the RAN to trigger the establishment of a data plane link between the terminal device and the user plane functional network element. The user plane functional network element stores the terminal device’s IP address, thereby generating a detection message 2 based on the IP address of the terminal device.

In the second way, the terminal device sends the first message including the IP address of the terminal device to the policy control function network element through the capability opening network element, and the policy control function network element sends the IP address of the terminal device to the session management function network element. The session management function network element sends the IP address of the terminal device to the user plane function network element, so that the user plane function network element can obtain the IP address of the terminal device, thereby generating a detection message 2 according to the IP address of the terminal device.

S412, the user plane function network element sends a detection message 2 to the terminal device according to the first forwarding rule, and the terminal device receives the detection message 2 sent by the user plane function network element at time T2 (for example, it may be the second time).

S413: The terminal device determines the delay information between the terminal device and the user plane functional network element according to T1 and T2. The terminal device can determine whether to initiate service data based on the delay information.

Specifically, assuming that the transmission delay of the uplink and downlink is symmetric, the terminal device can determine the delay information of the service data between the terminal device and the user plane functional network element according to T1 and T2, for example, the delay is (T2-T1 )/2.

S415. The capability opening network element sends the delay information to the policy control function network element, so that the policy control function network element determines whether to adjust the service data delay information.

In the second case, the second message includes QoS information, that is, in this case, the user plane function network element determines the QoS information. Before the terminal device receives the second message sent by the core network element network element through the application program interface, the method further includes: the terminal device receives the third detection message from the user plane function network element, and the source address of the third message is the user plane function The IP address of the network element, the destination address of the third message is the IP address of the terminal device; the terminal device obtains the IP address of the user plane function network element in the third detection message; the terminal device sends the fourth to the user plane function network element In the detection message, the source address of the fourth message is the IP address of the terminal device, and the destination address of the fourth message is the IP address of the user plane functional network element. The user plane function network element may determine the delay information according to the time when the third detection packet is sent and the time when the fourth detection packet is received, and the delay information is the delay information of the service data.

Optionally, the third detection packet and the fourth detection packet have the same configuration parameters, for example, the third detection packet and the fourth detection packet have the same size, and the third detection packet and the fourth detection packet have the same size. The transmission frequency is the same, and the duration of the third detection message and the fourth detection message are the same.

Optionally, the third detection message and the fourth detection message have the same service type as the service data. Therefore, the delay information determined according to the third detection message and the fourth detection message is the same as the delay information of the service data. That is to say, before the service data is initiated, the delay information of the service data after initiation can be accurately measured and obtained.

Optionally, in the second case, the user plane functional network element may send the determined QoS information to the policy control function network element through the control plane network element port, so that the policy control function network element determines whether the QoS of the service data Information to adjust.

The second case will be described below with reference to FIG. 5 using QoS information as the delay information. The method 500 includes:

The detection packet 3 and the detection packet 4 have the same configuration parameters, for example, the detection packet 3 and the detection packet 4 have the same size, the same transmission frequency, and the same duration.

S510. The terminal device sends a detection message 4 to the user plane functional network element, and the user plane function network element receives the detection packet 4 at time T4 (for example, the second time in method 700).

The terminal device can obtain the delay information in the second message according to the delay information Determine whether to initiate business data. For example, when the delay is large, the terminal device may determine to temporarily not initiate service data.

In a possible implementation, the first detection message and the second detection message in the above-mentioned first case may be Internet packet probe (packet internet groper, ping) packets. Similarly, the third detection message and the fourth detection message in the second case may be Ping packets. Among them, the Ping packet principle is: a personal computer (PC) uses the uniqueness of the machine's IP address on the network to send a message to the target IP address, and then asks the other party to return a message of the same size to determine the two network machines Whether it is connected, and what is the delay. The difference between the time when the PC connected to the terminal device sends out the message and the time when it receives the response message is the result of delay statistics.

The first forwarding rule and the forwarding rule of service data between the terminal device and the user plane functional network element contain the same quality of service QoS information.

Among them, the first forwarding rule and the forwarding rule of the service data between the terminal device and the user plane functional network element contain the same quality of service QoS information, which can be understood as: the first forwarding rule is used to determine the detection message and the detection message is determined The QoS information is the same as the QoS information determined by using the forwarding rules of business data, for example, the same delay information and the same packet loss rate.

It should be noted that the first forwarding rule refers to the description in the method 600. In the embodiment of the present application, the first forwarding rule is a rule followed by the user plane function network element sending the detection message. Optionally, the first forwarding rule may be determined based on a first message sent by the terminal device through the application program interface before initiating the data service, and the first message is used to request measurement of the service between the terminal device and the user plane function network element Data QoS information.

S720. The user plane function network element generates a first detection packet of service data.

Optionally, the first forwarding rule may include configuration information, for example, it may include at least one of the size of the detection message, the frequency of sending the detection message, or the duration of sending the detection message. In this way, the user plane function network element may generate the first detection message according to at least one of the size of the detection message, the frequency of sending the detection message, or the duration of sending the detection message.

Optionally, the first forwarding rule may not include configuration information, for example, does not include at least one of the size of the detection message, the frequency of sending the detection message, or the duration of sending the detection message. However, the session management function network element still needs to send the configuration information to the user plane function network element through the fourth message. In this way, the user plane functional network element can generate the first detection message according to the configuration information.

S730. The user plane function network element sends a first detection message to the terminal device according to the first forwarding rule.

Optionally, the method 700 further includes:

S740. The user plane function network element receives the second detection message sent by the terminal device.

Optionally, the first detection message and the second detection message have the same service type as the service data.

As an optional embodiment, the user plane function network element receives second indication information from the session management function network element, and the second indication information is used to instruct the user plane function network element not to perform the first detection message and the second detection message Billing operation. The user plane function network element does not perform a charging operation on the first detection message and the second detection message according to the second instruction information.

Optionally, the second indication information may be sent by the policy control function network element to the user plane function network element through the session management function network element. Optionally, the second indication information may be determined by the session management function network element and sent to the user plane function network element.

Optionally, the source address of the first detection message is the IP address of the user plane functional network element, and the destination address of the first detection message is the IP address of the terminal device. The source address of the second detection message is the IP address of the terminal device, and the destination address of the second detection message is the IP address of the user plane functional network element. That is, when the first detection message sent by the user plane function network element to the terminal device needs to obtain the IP address of the terminal device. For the manner in which the user plane function network element obtains the IP address of the terminal device, see S411.

The following is described in two cases. The first case is that the user plane function network element measures QoS information, and the second case is that the terminal device determines the QoS information.

In the first case, taking the QoS information as the delay information as an example, the user plane function network element sends the first detection message to the terminal device at the first time (for example, T3 in method 500) (for example, method 500 Detection packet 3) in the user plane function; at the second moment, the user plane function network element receives the second detection packet sent by the terminal device (for example, the detection packet 4 in the method 500). The first time is before the second time, and the user plane function network element determines the delay information according to the first time and the second time, and the delay information is the delay information of the service data. In other words, the delay information determined according to the transmission time of the first detection message and the reception time of the second detection message is the delay information of the service data between the terminal device and the user plane functional network element.

Optionally, the user plane function network element receives first indication information from the session management function network element, and the first indication information is used to instruct the user plane function network element to measure delay information; the user plane function network element is based on the first time and the second time Determining the delay information includes: the user plane function network element determines the delay information according to the first indication information, the first time, and the second time.

Optionally, the first indication information may be that the policy control function network element is sent to the user plane function network element through the session management function network element. Optionally, the first indication information may be determined by the session management function network element and sent to the user plane function network element.

Optionally, after the user plane functional network element determines the delay information, the user plane functional network element may send the delay information to the policy control function network element through the session management function network element.

Optionally, the user plane functional network element may also determine QoS information, and the determined QoS information may be sent to the policy function network element through the session management function network element.

In the second case, the user plane function network element receives the second detection message sent by the terminal device (for example, it may be detection message 1 in method 400). The user plane function network element sends a first detection message to the terminal device (for example, it may be detection message 2 in method 400). In other words, the user plane function network element cooperates with the terminal device to receive and send a detection message, so that the terminal device determines the QoS information.

Optionally, in the method 700, the first detection message and the second detection message are Internet packet probe Ping packets.

Therefore, in the method for measuring service quality information provided by the embodiments of the present application, before initiating service data, the terminal device may send a first message to the core network element through the application program interface to request the measurement terminal device and the user plane function network QoS information of business data between the elements. The user plane function network element or terminal device can determine the QoS information of the service data by the time of sending the detection message and receiving the detection message. Since the QoS information is the delay information after the service data is initiated, the terminal device can use the QoS information Decide whether to initiate business data to help improve the user experience. Alternatively, the policy control function network element may determine whether the QoS information of the service data needs to be adjusted according to the QoS information to meet the terminal device's demand for the QoS information of the service data, thereby helping to improve the user experience.

The following uses QoS information as a delay information as an example, and describes the method for measuring quality of service information provided by the embodiments of the present application with reference to FIGS. 8 and 9.

The first message is used to request measurement of service quality QoS information of service data between the terminal device and the user plane functional network element. That is, the first message is used to trigger the NEF to interact with the PCF.

Specifically, it may be that when the UE starts an application, before performing data services, the UE sends a first message to the NEF through the API, and the NEF sends the first message to the PCF. For example, the first message may be a QoS monitoring configuration request (QoS monitoring configuration request). configuration) request) message. Optionally, the first message includes one or more of information such as the IP address of the UE, the identification of the service type of the service data, the application ID (application ID) associated with the service data, or configuration information. The configuration information includes at least one of parameters such as the size of the Ping packet, the frequency of sending the Ping packet, or the duration of sending the Ping packet.

Optionally, before S801, the method further includes: before initiating the service data, the UE determines the DNN and S-NSSAI associated with the application according to locally stored user routing policy (UESP) information (URSP) The UE sends a session establishment request to the AMF through the RAN to trigger the establishment of the data plane link between the UE and the user plane functional network element.

Through the session establishment process, the AMF network element selects the SMF network element associated with the session. The SMF network element assigns an IP address to the UE. The IP address is used by the UE to transmit service packets. At the same time, the SMF network element stores the UE ID and session ID. IP addresses of DNN, S-NSSAI and UE, etc.

S802. After receiving the first message, the NEF sends the first message to the PCF.

S803, after receiving the first message sent by the NEF, the PCF determines the delay information of the Ping packet to trigger measurement of the current message when determining the current message according to the first message. The PCF generates a policy charging control (policy) for the UE or the service type or the application's Ping packet according to at least one of the UE's IP address, service data service type identifier, and service data associated application identifier included in the first message and charging control (PCC) rules, where the PCC rules contain QoS rules, that is, the QoS rules may be the aforementioned first forwarding rules, and the QoS rules are consistent with the QoS rules of the UE or the service type or the application (ie, Ping The QoS rule of the packet has the same 5QI and/or ARP as the QoS rule of the UE or the service type or the application, so that the UE or the service type or the application can be associated with the Ping packet.

Optionally, if the service data is guaranteed rate (GBR), the PCF may also determine the bandwidth according to parameters such as the size of the ping packet, the frequency of packet transmission, and the duration.

Optionally, S806 may be after or before S805, which is not limited in this embodiment of the present application.

S807. The PCF sends a second message to the NEF. For example, the second message may be a QoS monitoring response (QoS monitoring response) message. The second message includes a destination IP address (that is, an UPF IP address) used for Ping packet detection.

In S808, the NEF sends a second message to the API of the terminal device, so that the IP address of the UPF in the second message can be returned to the UE through the API.

S809, the UE receives the second message sent by the NEF through the API, and constructs the first Ping packet according to the IP address of the UPF in the second message (for example, it may be the first detection message in the method 300 or the detection message in the method 400 1 or the second detection message in the second case in method 700), the source IP of the first ping packet is the IP address of the UE, and the destination IP is the IP address of the UPF.
