Taking the measurement delay as an example, for example, the terminal device records that the time when the uplink data packet is sent to the user plane functional network element is T1, after the user plane functional network element sends the uplink data packet to the application server, the application server sends the downlink data packet to the terminal device through the user plane functional network element, and the terminal device records that the time when the downlink data packet is received is T2, then the terminal device may calculate the round-trip delay of the data packet to be T2-T1, and assuming that the transmission delays of the uplink and downlink are symmetric, it may be estimated that the transmission delays of the data packet in the uplink and downlink are (T2-T1)/2, respectively. However, the above method for measuring QoS information cannot measure whether the QoS information of the link between the terminal device and the user plane functional network element really meets the user's expectation, so how to measure the QoS information of the service data between the terminal device and the user plane functional network element is a problem to be solved by the embodiment of the present application. For another example, taking the measurement of the network speed as an example, when the user is not satisfied with the current network speed, the user may apply for a traffic acceleration packet, such as "for any me" traffic acceleration packet service of china mobile, where the traffic acceleration packet service indicates that the speed is increased on the basis of the original broadband, and the cost is 15 yuan per month, for example, the original network speed is 2 mbits/sec, and after participating in the speed increase, the network speed is increased to 4 mbits/sec to 8 mbits/sec. As shown in fig. 2, it is assumed that the third-party application server is measuring the network speed, and the third-party application server measures the network speed between the terminal device and the third-party application server, but after the traffic acceleration packet service is used for acceleration, the network speed between the terminal device and the core network element is increased, while the third-party application server measures the network speed between the terminal device and the third-party application server, and there is no method for measuring the QoS information between the terminal device and the user plane functional network element. Therefore, after applying for the traffic acceleration packet, it is measured that whether the network speed between the terminal device and the user plane functional network element reaches the expected value through the third-party application server, in other words, after the user spends money on the traffic acceleration packet service, whether the money spent by the user really reaches the expected value, and the third-party application server cannot accurately measure, so that it cannot be determined whether the current network environment is suitable for initiating service data, and user experience is reduced.
The embodiment of the application provides a method for measuring QoS information, and a terminal device can request to measure QoS information of service data between the terminal device and a user plane function network element in a current network environment through an application program interface at any time before service data is initiated. For example, when the terminal device is located in a geographic location with a poor network environment, such as a subway station, a train station, or other people traffic aggregation area, the terminal device may obtain that the current network environment cannot meet the user requirement by requesting to measure actual QoS information of a certain service in the network environment, and then the terminal device may select a geographic location with a good network environment, such as an office park, to initiate data packet transmission of the service, so as to obtain 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 equipment can selectively perform service in the network environment with better actual QoS information, and the user experience can be improved.
A method for measuring quality of service information in an embodiment of the present application is described below with reference to the accompanying drawings.
Fig. 3 illustrates a method for measuring quality of service information provided by an embodiment of the present application, including:
s310, before the terminal device initiates service data, sending a first message to a core network element through an Application Programming Interface (API), where the first message is used to request to measure quality of service (QoS) information of the service data between the terminal device and a user plane function network element.
The core network element is not limited in this embodiment of the application, for example, the core network element may be an NEF network element in fig. 1, the terminal device sends the first message to the NEF through the application program interface before initiating the service data, and the NEF may pass the first message through to the PCF.
Optionally, the QoS information comprises latency information.
Optionally, the first message includes at least one of an Internet Protocol (IP) address of the terminal device, an identifier of a service type of the service data, an application identifier associated with the service data, or a configuration parameter. 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 sent 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 identifier of the service type of the service data, the policy control function network element may determine the service type that requires QoS information measurement according to the identifier of the service type of the service data. That is, the identification of the traffic type of the traffic data is used to determine the traffic type for which QoS information measurements need to be made.
When the first message includes the application identifier associated with the service data, the policy control function network element may determine, according to the application identifier associated with the service data, an application that requires QoS information. That is, the application identification associated with the traffic data is used to determine the application that needs to perform the QoS information.
When the first message includes the configuration parameter, the user plane functional network element may generate a detection packet according to the configuration parameter. That is, the configuration parameters are used to detect the generation of the message. For example, after receiving the first message transparently transmitted by the NEF, the PCF sends the configuration parameters in the first message to the user plane functional network element via the SMF, so that the user plane functional network element may generate a detection message according to one or more of the size of the detection message, the frequency of sending the detection message, and the duration of sending the detection message, thereby detecting the QoS information of the service data between the terminal device and the user plane functional network element using the detection message.
S320, the terminal device receives a second message sent by the core network element through the application program interface, where 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 also be measured by the user plane network element. In the example where the terminal device measures the QoS information, the second message is used to trigger the measurement of the QoS information. In an example where the user plane function network element measures QoS information, the second message includes the QoS information measured by the user plane function network element. For example, the second message may be a response message to the first message.
Therefore, in this embodiment of the present application, before initiating service data, the terminal device may send a first message requesting to measure QoS information to a core network element (for example, a NEF network element) through an application program interface, and after the core network element sends parameters in the first message to the user plane function network element through the PCF and the SMF, the user plane function network element may measure QoS information based on the parameters in the first message and send the QoS information to the application program interface of the terminal device through a second message. Alternatively, the core network element may trigger the terminal device to measure the QoS information by sending a second message to an application program interface of the terminal device. The QoS information in the embodiment of the application is the QoS information of the service data to be initiated, which is measured before the service data is initiated, and the QoS information between the terminal equipment and the user plane functional network element is measured, so that the accuracy of measuring the QoS information can be improved, and the improvement of user experience is facilitated. For example, when the terminal device is located in a geographic location with a poor network environment, such as a subway station, a train station, or other people traffic aggregation area, the terminal device may obtain that the current network environment cannot meet the user requirement by requesting to measure actual QoS information of a certain service in the network environment, and then the terminal device may select to transmit a data packet of the service at the geographic location with the good network environment, such as an office park, to obtain 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 equipment can selectively perform service in the network environment with better actual QoS information, and the user experience can be improved.
The method for measuring the service quality information in the embodiment of the present application is described below in two cases. The first case is that the terminal device measures QoS information. The second case is that the user plane function 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 may send the measured QoS information to the policy control function network element through the session management function network element, the policy control function network element may send the QoS information to the NEF through the second message, and the NEF sends the second message to the application program interface of the terminal device.
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 network element of the core network through the application program interface, the method further includes:
the terminal equipment sends a first detection message to a user plane function network element at a first moment;
the terminal equipment receives a second detection message from the user plane functional network element at a second moment;
and the terminal equipment determines delay information according to the first time and the second time, wherein the delay information is the delay information of the service data.
Optionally, the first detection packet and the second detection packet have the same configuration parameters, for example, the sizes of the first detection packet and the second detection packet are the same, the sending frequencies of the first detection packet and the second detection packet are the same, and the durations of the first detection packet and the second detection packet are the same.
Optionally, the first detection packet and the second detection packet are the same as the service type of 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, before the service data is initiated, the delay information of the service data after the initiation can be accurately measured.
Optionally, the source address of the first detection packet is an IP address of the terminal device, the destination address of the first detection packet is an IP address of the user plane function network element, the source address of the second detection packet is an IP address of the user plane function network element, and the destination address of the second detection packet is an IP address of the terminal device.
Optionally, before generating the first detection packet, the terminal device needs to acquire an IP address of the user plane function network element. In a possible implementation manner, the second message includes an IP address of the user plane function network element, and the terminal device may obtain the IP address of the user plane function 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 then sends a second message including the IP address of the user plane function network element to the application program interface of the terminal device. For another example, the SMF may directly send the IP address of the user plane function network element to the NEF, and the NEF then sends a second message including the IP address of the user plane function network element to the application program interface of the terminal device, or the NEF sends the second message to the application program interface of the terminal device, and then sends the IP address of the user plane function network element to the application program interface of the terminal device through a 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 the configuration parameter, for example, the core network element may be NEF, when the NEF receives the first message, the first message is sent to the PCF, and the PCF sends the configuration parameter in the first message to the UPF through the SMF, so that the UPF may generate the second detection packet according to the configuration parameter, thereby sending the second detection packet to the terminal device. The terminal device may determine the delay information according to the time (first time) of sending the first detection packet and the time (second time) of receiving the second detection packet, where the delay information is the delay information of the detection packet between the terminal device and the user plane function network element. For example, if the first time is t1 and the second time is t2, the terminal device may determine the round-trip delay information of the detected packet to be t2 to t1, and if the uplink and the downlink are symmetric, the uplink and the downlink delay information of the detected packet are (t2 to t1)/2, although the method of determining the delay information is not limited thereto.
In the first case, the terminal device may determine the QoS information of the service data between the terminal device and the user plane functional network element according to the time of sending the first detection packet and the time of receiving the second detection packet, so that the QoS information is determined by the terminal device itself, and the trust level of the terminal device on the QoS information may be improved.
Optionally, in the first case, the terminal device may send the determined QoS information to the capability openness network element through the application program interface, and the capability openness network element sends the QoS information to the policy control function network element, so that the policy control function network element determines whether to adjust the QoS information of the service data.

Thus, the user plane functional network element can generate a first detection message according to the configuration information.
And S730, the user plane functional network element sends a first detection message to the terminal equipment according to the first forwarding rule.
Optionally, the method 700 further comprises:
s740, the user plane functional network element receives the second detection packet sent by the terminal device.

Optionally, the first detection packet and the second detection packet are the same as the service type of the service data.
As an optional embodiment, the user plane function network element receives second indication information from the session management function network element, where the second indication information is used to indicate that the user plane function network element does not perform a charging operation on the first detection packet and the second detection packet. And the user plane functional network element does not perform charging operation on the first detection message and the second detection message according to the second indication information.
Optionally, the second indication information may be that the policy control function network element sends 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 packet is an IP address of the user plane function network element, and the destination address of the first detection packet is an 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 user plane function network element sends the first detection packet to the terminal device, the IP address of the terminal device needs to be acquired. The manner for the user plane function network element to acquire the IP address of the terminal device is referred to 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 QoS information.
In a first case, taking QoS information as delay information as an example, a user plane function network element sends a first detection message (for example, detection message 3 in method 500) to a terminal device at a first time (for example, T3 in method 500); the user plane function network element receives, at the second time, the second detection packet sent by the terminal device (for example, the detection packet 4 in the method 500). And the user plane functional network element determines delay information according to the first moment and the second moment, wherein the delay information is the delay information of the service data. In other words, the delay information determined according to the sending time of the first detection packet and the receiving time of the second detection packet 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, where the first indication information is used to indicate the user plane function network element to measure the delay information; the user plane function network element determines time delay information according to the first moment and the second moment, and the method comprises the following steps: and the user plane functional network element determines the time delay information according to the first indication information, the first moment and the second moment.
Optionally, the first indication information may be that the policy control function network element sends the policy control function network element 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 function network element determines the time delay information, the user plane function network element may send the time delay information to the policy control function network element through the session management function network element.
Optionally, the user plane function network element may also determine QoS information, and may send the determined QoS information to the policy function network element through the session management function network element.
In the second case, the user plane functional network element receives a second detection message (for example, the detection message 1 in the method 400) sent by the terminal device. The user plane function network element sends a first detection message (which may be, for example, detection message 2 in method 400) to the terminal device. In other words, the user plane functional network element receives and sends the detection message in cooperation with the terminal device, so that the terminal device determines the QoS information.
Optionally, in the method 700, the first detection packet and the second detection packet are internet packet probe Ping packets.
Therefore, in the method for measuring QoS information provided in this embodiment of the present application, before initiating service data, a terminal device may send a first message to a core network element through an application program interface to request for measuring QoS information of the service data between the terminal device and a user plane function network element. The user plane functional network element or the terminal equipment can determine the QoS information of the service data through the time for sending the detection message and the time for receiving the detection message, and the terminal equipment can determine whether to initiate the service data according to the QoS information because the QoS information is the time delay information after the service data is initiated, so that the user experience is improved. Or, the policy control function network element may determine whether to adjust the QoS information of the service data according to the QoS information, so as to meet the requirement of the terminal device for the QoS information of the service data, thereby facilitating improvement of user experience.
