[0087] First, an embodiment of the present disclosure provides a performance measurement method, which can be executed by any electronic device with computing and processing capabilities.

[0088] Figure 1 The flowchart of a performance measurement method in an embodiment of the present disclosure is shown. As Figure 1 shown, the performance measurement method provided in the embodiment of the present disclosure is applied to the user plane function and includes the following steps:

[0089] S102, when a protocol data unit (PDU) session is established or modified, receive a performance measurement request sent by the session management function.

[0090] S104, monitor at least one of the uplink packet delay data and the downlink packet delay data corresponding to the packets of the PDU session between the user equipment and the user plane function.

[0091] The data packet of the PDU session is a General Packet Radio Service Tunneling Protocol PDU monitoring response data packet for performance measurement; in one embodiment, the data packet of the PDU session includes but is not limited to: at least one of the data packet of the satellite backhaul type PDU session and the data packet of the single network slice selection assistance information PDU session; for example, the data packet of the single network slice selection assistance information PDU session can be measured separately, the data packet of the satellite backhaul type PDU session can be measured separately, and the data packet of the satellite backhaul type PDU session and the data packet of the single network slice selection assistance information PDU session can also be measured jointly.

[0092] In one embodiment, the satellite backhaul type can be a dynamic satellite backhaul type.

[0093] In one embodiment, when receiving a performance measurement request sent by the session management function, at least one of the uplink data packet delay data and the downlink data packet delay data corresponding to the data packet of the PDU session between the user equipment and the user plane function is monitored based on the monitoring policy of the policy control function.

[0095] In one embodiment, based on at least one of the data such as the uplink data packet delay data and the downlink data packet delay data, the target link change data is determined, and the performance measurement policy is adjusted according to the target link change data; specifically, the target link change data is the data of the uplink data packet delay data and the downlink data packet delay data greater than the delay threshold, and the performance measurement policy can be adjusted according to the target link change data, etc., for example, reducing the priority of one or more transceivers, etc.; the operator can timely discover the link state change according to the measurement result, and then adjust the QoS policy to ensure the user's service experience.

[0096] In the above embodiments, when the UPF uses the satellite backhaul type according to the request indication received from the SMF during the PDU session establishment or modification process, QoS monitoring is performed for each QoS flow of each user equipment, both the current network information model and the measurement method are enhanced. While performing individual measurements for each S-NSSAI, a method for performing QoS monitoring for the satellite backhaul type is added, as well as joint measurements for the satellite backhaul type and the S-NSSAI, breaking the limitation in the related art that only QoS monitoring for URLLC services can be supported, improving the operator's control over the network status, helping the operator to discover and solve network link problems in a timely manner, being able to make corresponding QoS adjustment strategies for the delay changes caused by the satellite backhaul type, and ensuring the service quality of satellite services.

[0097] Figure 2 The flowchart of a method for monitoring packet delay data in an embodiment of the present disclosure is shown. As Figure 2 shown, the method for monitoring packet delay data provided in the embodiment of the present disclosure is applied to the user plane function and includes the following steps:

[0101] In one embodiment, at least one of the packets of the satellite backhaul type PDU session and the packets of the single Network Slice Selection Assistance Information PDU session can be monitored through each sub-counter.

[0102] In one embodiment, record the monitoring data corresponding to the packets of each received PDU session that needs to perform quality of service monitoring; specifically, record the timestamps and information corresponding to the following monitoring data in the General Packet Radio Service User Plane Part GTP-U header of the packets of each received PDU session that needs to perform quality of service monitoring.

[0103] Among them, the monitoring data includes but is not limited to at least one of the following:

[0106] The third monitoring value, the local time when the radio access network sends an uplink packet;

[0107] The fourth monitoring value, the local time when the user plane function receives an uplink data packet;

[0108] The fifth monitoring value, the measurement result of the downlink delay from the radio access network to the user equipment;

[0109] The sixth monitoring value, the measurement result of the uplink delay from the radio access network to the user equipment.

[0110] In one embodiment, the measurement result of the downlink delay and the measurement result of the uplink delay include but are not limited to: at least one of the delay occurring in the radio access network and the delay on the Uu interface; for example, the sum of the delays occurring in at least one radio access network, the sum of the delays on at least one Uu interface, the sum of the delays occurring in at least one radio access network and the delays on at least one Uu interface, etc.

[0111] In one embodiment, the delay occurring in the radio access network includes but is not limited to: at least one of the user plane of the next-generation base station central unit, the user plane of the F1 interface, the next-generation base station distributed unit, etc.

[0112] S206, independently calculate the monitoring data corresponding to each sub-counter to obtain at least one of the uplink data packet delay data and the downlink data packet delay data.

[0113] In one embodiment, calculate the downlink data packet delay data according to the first monitoring value, the second monitoring value, and the fifth monitoring value.

[0114] In one embodiment, the downlink data packet delay data includes but is not limited to: at least one of data such as the average downlink data packet delay data and the downlink data packet delay distribution data.

[0115] The average downlink data packet delay data is the ratio of the sum of the downlink data values of the data packets of multiple PDU sessions to the number of data packets of the PDU session.

[0116] The downlink data packet delay distribution data is the number of data packets of the PDU session that satisfy the downlink data value within the delay range.

[0117] In one embodiment, calculate the downlink data value of the data packet of each PDU session based on each sub-counter according to the first monitoring value, the second monitoring value, the fifth monitoring value, etc. of the data packet of each PDU session. The downlink data value is the first difference between the second monitoring value and the first monitoring value, and / or the sum of the first difference and the fifth monitoring value.

[0118] In one embodiment, determine the uplink data packet delay data according to the third monitoring value, the fourth monitoring value, and the sixth monitoring value.

[0119] In one embodiment, the uplink packet delay data includes, but is not limited to, at least one of average uplink packet delay data and uplink packet delay distribution data.

[0120] The average uplink packet delay data is the ratio of the sum of the uplink data values of the packets of all PDU sessions to the number of packets of the PDU sessions.

[0121] The uplink packet delay distribution data is the number of packets of the PDU sessions that satisfy the uplink data value within the delay range.

[0122] In one embodiment, based on each sub-counter, the uplink data value of the packets of each PDU session is calculated according to the third monitoring value, the fourth monitoring value, the sixth monitoring value, etc. of the packets of each PDU session, and the uplink data value is the second difference between the fourth monitoring value and the third monitoring value, and / or the sum of the second difference and the sixth monitoring value.

[0123] In one embodiment, when the user plane function is not synchronized with the radio access network time, data such as the first monitoring value, the second monitoring value, the third monitoring value, the fourth monitoring value, the first difference, the second difference, etc. can be adjusted, and then the uplink packet delay data, the downlink packet delay data, etc. are calculated. For example, when the local time of the user plane function is 1 s faster than the radio access network time, the first monitoring value after subtracting 1 s is used to calculate the uplink packet delay data, the downlink packet delay data, etc.

[0124] In the above embodiment, if the request received by the user plane function from the SMF indicates the use of the satellite backhaul type, the request executes QoS monitoring to measure the uplink / downlink packet delay between the user equipment and the PSA UPF. The operator can timely discover the change of the link state according to the measurement result, and then adjust the QoS policy to ensure the user's service experience.

[0130] In one embodiment, the AMF needs to notify the SMF of the satellite backhaul category corresponding to the PDU session in the session establishment process. If the satellite backhaul category received by the SMF is the satellite backhaul type, it will instruct the PCF to trigger performance measurement, and the UPF monitors the delay of the packets of the PDU session between the user terminal and the user plane function.

[0153] In the above embodiment, when the UPF uses the satellite backhaul type according to the request indication received from the SMF during the establishment or modification of the PDU session, QoS monitoring is performed for each QoS flow of each user equipment, both the current network information model and the measurement method are enhanced. While performing separate measurements for each S-NSSAI, a method for performing QoS monitoring for the satellite backhaul type is added, as well as joint measurements for the satellite backhaul type and S-NSSAI, breaking the limitation in the related art that only QoS monitoring for URLLC services can be supported, improving the operator's control over the network status, helping the operator to discover and solve network link problems in a timely manner, being able to make corresponding QDS adjustment strategies for the delay changes caused by the satellite backhaul type, and ensuring the service quality of satellite services.

[0154] Figure 6 The following shows a schematic diagram of another performance measurement device in the embodiments of the present disclosure, as Figure 6 shown, the performance measurement device 6 includes: a condition configuration module and a result generation module;

[0155] The condition configuration module configures the performance measurement method execution conditions in the session management function. Among them, the performance measurement method execution conditions include: the satellite backhaul type;

[0156] The result generation module sends a performance measurement request including the performance measurement method execution conditions to the user plane function, so that the user plane function monitors at least one of the uplink data packet delay data and the downlink data packet delay data corresponding to the data packets of the PDU session between the user equipment and the user plane function.

[0157] In one embodiment, the result generation module is further configured such that the AMF needs to notify the SMF of the satellite backhaul category corresponding to the PDU session during the session establishment process. If the satellite backhaul category received by the SMF is the satellite backhaul type, it will instruct the PCF to trigger performance measurement, and the UPF monitors the delay of the data packets of the PDU session between the user terminal and the user plane function.

[0158] In the above embodiment, configuring the satellite backhaul type for QoS monitoring in the SMF and requesting the user plane function to perform QoS monitoring to measure the uplink / downlink data packet delay between the user equipment and the PSA UPF helps the operator to timely discover and solve network link problems and better develop satellite services.

[0163] T2: Indicates the local time when the NG-RAN receives the downlink GTP PDU monitoring data;

For example, the client of this application program can be a mobile phone client, a PC client, etc.

[0184] In the above embodiments, when the UPF uses the satellite backhaul type according to the request indication received from the SMF during the PDU session establishment or modification process, QoS monitoring is performed on each QoS flow of each user equipment, both the current network information model and the measurement method are enhanced. While performing separate measurements on each S-NSSAI, a method for performing QoS monitoring for the satellite backhaul type is added, as well as joint measurement of the satellite backhaul type and S-NSSAI, breaking the limitation in the related art that only QoS monitoring for URLLC services can be supported, improving the operator's control over the network status, helping the operator to discover and solve network link problems in a timely manner, and being able to make corresponding QoS adjustment strategies for the delay changes caused by the satellite backhaul type to ensure the service quality of satellite services.
