[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0034] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a delay adjustment method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1More or fewer components as shown, or with Figure 1 Different configurations are shown.

The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network.

[0036] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0037] In this embodiment, a delay adjustment method is provided. Figure 2 The process of the delay adjustment method according to the embodiment of the present invention is as follows Figure 1 ,like Figure 2 As shown, the process includes the following steps:

[0038] Step S202, determining uplink delay information for transmitting uplink data packets, wherein the uplink delay information includes: uplink air interface delay between the base station and the terminal, and uplink end-to-end delay between the terminal and the node device;

[0039] Step S204, determining downlink delay information for transmitting downlink data packets, wherein the downlink delay information includes: downlink air interface delay between the base station and the terminal, and downlink end-to-end delay between the terminal and the node device;

[0040] Step S206: Determine abnormal delay information from the uplink delay information and the downlink delay information according to the preset delay index, and adjust the abnormal delay information.

[0041] The execution subject of the above steps may be a processor provided in the node device, but is not limited thereto. The node device may be a node engine for performing message transmission with a terminal or a base station.

[0042] Optionally, the uplink data message includes message data and a message header, and the extended field of the message header includes the time when the uplink data message is transmitted between the terminal and the base station, and the time when the uplink data message is transmitted between the base station and the node device. The downlink data message includes message data and a message header, and the extended field of the message header includes the time when the downlink data message is transmitted between the base station and the node device, and the time when the downlink data message is transmitted between the base station and the terminal.

[0043] Optionally, the preset delay index can be set according to different application scenarios, for example, the delay scenario between the base station and the terminal, the delay scenario between the terminal and the node device, and the delay required by different application scenarios is different. It is mainly used to compare with the delay in the uplink delay information and the downlink delay information, and determine whether the delay abnormality occurs through the comparison result.

[0044] Through the above steps, since the uplink delay information and the downlink delay information are determined, the uplink delay information includes the uplink air interface delay between the base station and the terminal, and the uplink end-to-end delay between the terminal and the node device, and the downlink delay information includes the downlink air interface delay between the base station and the terminal, and the downlink end-to-end delay between the terminal and the node device, so that the end-to-end delay anomaly information can be accurately determined and the delay anomaly information can be adjusted. In this way, the end-to-end transmission delay can be guaranteed and the delay jitter can be weakened in time. Therefore, the problem that it is difficult to locate the position of the delay anomaly and the end-to-end transmission delay cannot be guaranteed in the related technology can be solved, and the position of the delay anomaly can be accurately located to ensure the effect of end-to-end transmission delay.

[0045] In an exemplary embodiment, uplink delay information for transmitting an uplink data message is determined, including: parsing a first uplink time, a second uplink time, and a third uplink time from the uplink data message, wherein the first uplink time is the time when the terminal sends the uplink data message, the second uplink time is the time when the base station receives the uplink data message, and the third uplink time is the time when the base station sends the uplink data message, and the first uplink time, the second uplink time, and the third uplink time are all set in the uplink data message; determining an uplink end-to-end delay using the first uplink time and the fourth uplink time, wherein the fourth uplink time is the time when the node device receives the uplink data message; determining an uplink air interface delay using the first uplink time, the second uplink time, and the processing time of the uplink data message by the base station, wherein the processing time of the uplink data message by the base station is determined using the second uplink time and the third uplink time; determining the uplink end-to-end delay, the uplink air interface delay, and the processing time of the uplink data message by the base station as the uplink delay information. In this embodiment, by acquiring each time when uplink data messages are sent between the terminal and the base station, the transmission time of the uplink data message in each stage can be accurately known, so that the specific position of the abnormal delay can be located.

[0046] In an exemplary embodiment, the first uplink time, the second uplink time, and the third uplink time are all set in the extension field of the message header in the uplink data message. In this embodiment, the message header includes a GTPU extension header and an IP extension header. For example, the first uplink time of the uplink data message sent by the terminal is entered in the IP extension header (including the extension field) of the uplink data message. The second uplink time of the uplink data message sent by the terminal received by the base station and the third uplink time of the uplink data message sent by the base station to the node device are entered in the GTPU extension header (including the extension field) of the uplink data message. The node device receives the fourth uplink time of the uplink data message sent by the base station and records it locally in the node device without operating the message header. The node device extracts the first uplink time from the IP extension header of the uplink data message, extracts the second uplink time and the third uplink time from the GTPU extension header of the uplink data message, and combines the fourth uplink time to summarize the uplink time and perform delay statistics and delay calculation, and judge the abnormal delay information. This embodiment uses the extended field to time-stamp the sending and receiving of the uplink message, so as to effectively obtain each uplink time and quickly locate the position of the delay anomaly.

[0047] In an exemplary embodiment, determining the downlink delay information of transmitting a downlink data message includes: parsing the first downlink time, the second downlink time, and the third downlink time from the downlink time sent by the terminal, wherein the first downlink time is the time when the node device sends the downlink data message, the second downlink time is the time when the base station receives the downlink data message, and the third downlink time is the air interface time when the terminal receives the downlink data message; using the first downlink time and the fourth downlink time to determine the downlink end-to-end delay, wherein the fourth downlink time is the time when the terminal decodes the IP message; using the second downlink time and the third downlink time to determine the downlink air interface delay; using the third downlink time and the fourth downlink time to determine the internal processing time of the terminal; determining the downlink end-to-end delay, the downlink air interface delay, and the processing time of the downlink data message by the base station as the downlink delay information. In this embodiment, the first downlink time, the second downlink time, and the third downlink time are all set in the extension field of the message header in the downlink data message. For example, the first downlink time when the node device sends downlink data is printed in the IP extension header (including the extension field) of the downlink data message. The second downlink time of the downlink data message sent by the node device received by the base station is entered in the IP extension header of the downlink data message. The third downlink time of the downlink data message sent by the base station is entered in the IP extension header of the downlink data message. The terminal records the fourth downlink time of the IP extension header locally in the terminal without operating the message header. After receiving the downlink data message, the terminal extracts the first downlink time, the second downlink time and the third downlink time in the IP extension header in the downlink data message, summarizes the first downlink time, the second downlink time, the third downlink time and the fourth downlink time, and obtains the downlink time. Optionally, in order to reduce the number of messages between the terminal and the node device, the terminal can aggregate multiple downlink time information into one message for sending. After receiving the message, the node device performs delay statistics and time calculation to quickly locate the location of the delay anomaly. This embodiment can accurately locate the location of the delay anomaly when sending the downlink data message by aggregating all downlink times.

[0048] In an exemplary embodiment, before determining the uplink delay information of transmitting the uplink data message, the above method also includes: sending a clock synchronization request to the base station; receiving a clock synchronization response from the base station in response to the clock synchronization request, wherein the clock synchronization response includes the clock information of the base station; calculating the clock deviation between the node device and the base station using the clock information of the base station in the clock synchronization response; calibrating the clock of the node device according to the clock deviation to maintain clock synchronization with the base station. In this embodiment, the node device can periodically send a clock synchronization request to the base station (for example, send a clock synchronization request according to the Network Time Protocol (NTP)), wait for and receive the NTP clock synchronization response sent by the base station; and calculate the clock deviation and calibrate the clock of the node device to maintain clock synchronization with the base station. The node device can maintain the alignment of the air interface frame number between the node device and the base station by periodically receiving the frame synchronization signal of the base station and reading the frame number and subframe number.

[0049] In an exemplary embodiment, the abnormal delay information is determined from the uplink delay information and the downlink delay information according to the preset delay index, and the abnormal delay information is adjusted, including: when the uplink air interface delay is greater than the first preset delay, and / or the downlink air interface delay is greater than the second preset delay, the adjustment of the 5G service quality flow identifier 5QI is initiated to determine the delay adjustment information, wherein the preset delay index includes the first preset delay and the second preset delay; the abnormal delay information is adjusted using the delay adjustment information. In this embodiment, when the air interface delay does not meet the preset delay index (for example, the service application tolerance delay threshold), the 5QI adjustment strategy is triggered, and the preset delay index reflects the jitter of the air interface. In addition, the preset delay index can also be adjusted. For example, when the air interface delay adjustment timer times out, it is necessary to determine whether the uplink air interface delay, downlink air interface delay and end-to-end compliance rate index (the compliance rate index reflects the jitter of the end-to-end network) are in the adjustment period. If they are in the adjustment period, the preset delay index will not be adjusted, and the adjustment will be made after the next judgment of entering the stable period; if they are in the stable period and the uplink air interface delay, downlink air interface delay and compliance rate indicators do not meet the threshold requirements of the service, the adjustment of the preset delay index is triggered. The adjustment of 5QI in this embodiment is applicable to scenarios where the air interface delay and compliance rate indicators deviate greatly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0050] Optionally, when the uplink air interface delay is greater than the first preset delay, and / or the downlink air interface delay is greater than the second preset delay, the adjustment of the 5G service quality flow identifier 5QI is started to determine the delay adjustment information. After that, the above method also includes: when the delay compliance rate of the uplink air interface delay and / or the downlink air interface delay is greater than the target delay, and the 5QI does not meet the delay requirements of the uplink air interface delay and / or the downlink air interface delay, triggering a reselection strategy, wherein the reselection strategy is used to reselect the target 5QI. For example, when the air interface delay and the target delay deviate from the service application tolerance delay threshold and the current 5QIQoS delay does not meet the service delay requirements, the 5QI reselection strategy is triggered. The node device statically selects 5QI or dynamically matches 5QI according to the delay requirements of the service application, finds a 5QI that meets the service delay requirements, and triggers the base station to execute the modification of 5QI. The adjustment of 5QI in this embodiment is applicable to scenarios where the air interface delay and compliance rate indicators deviate greatly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0051] Optionally, when the uplink air interface delay is greater than the first preset delay, and / or the downlink air interface delay is greater than the second preset delay, the adjustment of the 5G service quality flow identifier 5QI is initiated to determine the delay adjustment information. The above method also includes: sending the delay adjustment information to the base station to instruct the base station to perform adjustment of the 5QI to adjust the uplink air interface delay and / or the downlink air interface delay; when the adjusted air interface delay is less than the preset air interface delay, and the delay fluctuation of the adjusted air interface delay is greater than the preset fluctuation, determining an adjustment strategy, wherein the adjustment strategy includes an air interface delay adjustment amount, a delay deviation value between the adjusted air interface delay and the preset air interface delay, and the adjusted air interface delay includes an adjusted uplink air interface delay and / or an adjusted downlink air interface delay; and sending the adjustment strategy to the base station to instruct the base station to adjust the adjusted air interface delay according to the adjustment strategy. For example, if the current 5QIQoS delay meets the service delay requirements, but the air interface delay and delay compliance rate indicators still fluctuate and affect the service delay requirements, the air interface delay scheduling optimization strategy is started. The node device calculates the deviation and adjustment amount of the current delay, delay compliance rate, service expected delay and air interface delay compliance rate, and triggers the base station to perform air interface delay scheduling optimization. The base station adjusts the QoS parameter PDB value and retransmission failure rate according to the adjustment amount, remaps the HARQ transmission times and target BLER, and recalculates the scheduling strategy and scheduling priority to ensure the QoS delay requirements.

[0052] In an exemplary embodiment, before determining the abnormal delay information from the uplink delay information and the downlink delay information according to the preset delay index and adjusting the abnormal delay information, the above method also includes: triggering an alarm message when the uplink end-to-end delay is greater than the first preset delay, and / or the downlink end-to-end delay is greater than the second preset delay, wherein the alarm message is used to indicate that abnormal delay information occurs in the uplink end-to-end delay or the downlink end-to-end delay, wherein the preset delay index includes the first preset delay and the second preset delay; sending an abnormal log collection instruction to the base station and the terminal to instruct the base station to collect abnormal logs; receiving the abnormal logs sent by the base station and the terminal, and determining the delay adjustment information according to the abnormal logs, wherein the delay adjustment information is used to adjust the abnormal delay information. This embodiment can quickly determine the abnormal information by means of logs.

[0053] In this embodiment, a delay adjustment method is provided. Figure 3 The process of the delay adjustment method according to the embodiment of the present invention is as follows Figure 2 ,like Figure 3 The process includes the following steps:

[0054] Step S302, sending the uplink delay information of the transmitted uplink data message to the node device, wherein the uplink delay information includes: the uplink air interface delay between the base station and the terminal, and the uplink end-to-end delay between the terminal and the node device;

[0055] Step S304: Send the downlink data message to the terminal to instruct the terminal to send the downlink delay information of the downlink data message to the node device, wherein the downlink delay information includes: the downlink air interface delay between the base station and the terminal, and the downlink end-to-end delay between the terminal and the node device;

[0056] Step S306: receiving the delay adjustment information sent by the node device, and adjusting the delay anomaly information according to the delay adjustment information, wherein the delay anomaly information is determined by the node device from the uplink delay information and the downlink delay information.

[0057] The execution subject of the above steps may be a base station, but is not limited thereto.

[0058] Optionally, the uplink data message includes message data and a message header, and the message header includes the time when the uplink data message is transmitted between the terminal and the base station, and the time when the uplink data message is transmitted between the base station and the node device. The downlink data message includes message data and a message header, and the message header includes the time when the downlink data message is transmitted between the base station and the node device, and the time when the downlink data message is transmitted between the base station and the terminal.

[0059] Optionally, the downlink air interface delay and the downlink end-to-end delay are determined by the time for transmitting downlink data messages between the base station and the node device and the time for transmitting downlink data messages between the base station and the terminal.

[0060] Through the above steps, since the uplink delay information and the downlink delay information are determined, the uplink delay information includes the uplink air interface delay between the base station and the terminal, and the uplink end-to-end delay between the terminal and the node device, and the downlink delay information includes the downlink air interface delay between the base station and the terminal, and the downlink end-to-end delay between the terminal and the node device, so that the end-to-end delay anomaly information can be accurately determined and the delay anomaly information can be adjusted. In this way, the end-to-end transmission delay can be guaranteed and the delay jitter can be weakened in time. Therefore, the problem that it is difficult to locate the position of the delay anomaly and the end-to-end transmission delay cannot be guaranteed in the related technology can be solved, and the position of the delay anomaly can be accurately located to ensure the effect of end-to-end transmission delay.

[0061] In an exemplary embodiment, before the uplink delay information of the transmitted uplink data message is sent to the node device, the above method also includes: receiving the uplink data message sent by the terminal, wherein the extension field of the message header in the uplink data message includes the first uplink time; setting the second uplink time and the third uplink time in the extension field of the message header of the uplink data message, wherein the second uplink time is the time when the base station receives the uplink data message, and the third uplink time is the time when the base station sends the uplink data message. In this embodiment, the message header includes a GTPU extension header and an IP extension header. For example, the first uplink time when the terminal sends the uplink data message is entered in the IP extension header (including the extension field) of the uplink data message. The second uplink time when the base station receives the uplink data message sent by the terminal and the third uplink time when the base station sends the uplink data message to the node device are entered in the GTPU extension header (including the extension field) of the uplink data message. The node device receives the fourth uplink time of the uplink data message sent by the base station, and records it locally in the node device without operating the message header. The node device extracts the first uplink time from the IP extension header of the uplink data message, extracts the second uplink time and the third uplink time from the GTPU extension header of the uplink data message, and combines the fourth uplink time to summarize the uplink time and perform delay statistics and delay calculation to judge the abnormal delay information. This embodiment uses the extension field to time-stamp the sending and receiving of the uplink message, which can effectively obtain each uplink time and quickly locate the location of the delay anomaly.

[0062] In an exemplary embodiment, before sending the uplink delay information of the transmitted uplink data message to the node device, the method further includes: broadcasting system information according to a first preset period, wherein the system information includes clock information of the base station, and the system information is used to instruct the terminal to maintain clock synchronization with the base station. In this embodiment, the terminal can periodically read the system information, and obtain the coordinated universal time UTC time by reading the single frequency network (SFN) data frame in the system information, so as to achieve clock synchronization and frame synchronization between the terminal and the base station.

[0063] In an exemplary embodiment, before the uplink delay information of the transmitted uplink data message is sent to the node device, the above method also includes: receiving a clock synchronization request sent by the node device; responding to the clock synchronization request, sending a clock synchronization response to the node device, wherein the clock synchronization response includes the clock information of the base station, and the clock synchronization response is used to instruct the node device to calculate the clock deviation between the node device and the base station. For example, the node device can periodically send a clock synchronization request (for example, a Network Time Protocol (NTP) clock synchronization request) to the base station, wait for and receive the NTP clock synchronization response sent by the base station; and calculate the clock deviation and calibrate the clock of the node device to keep it synchronized with the base station clock. The node device can also keep the node device and the base station air interface frame number aligned by periodically receiving the frame synchronization signal of the base station, reading the frame number and subframe number.

[0064] In an exemplary embodiment, before sending the downlink data message to the terminal, the method further includes: receiving a downlink data message sent by a node device, wherein the extension field of the message header in the downlink data message includes a first downlink time and a second downlink time, the first downlink time is the time when the node device sends the downlink data message, and the second downlink time is the time when the base station receives the downlink data message; setting the third downlink time in the extension field of the message header in the downlink data message to obtain the downlink data message, wherein the third downlink time is the air interface time when the terminal receives the downlink data message. In this embodiment, the first downlink time, the second downlink time and the third downlink time are all set in the extension field of the message header in the downlink data message. For example, the first downlink time when the node device sends downlink data is entered in the IP extension header of the downlink data message. The second downlink time when the base station receives the downlink data message sent by the node device is entered in the IP extension header of the data message. The third downlink time when the base station sends the downlink data message is entered in the IP extension header of the data message. The time when the terminal decrypts the IP extension header (i.e., the fourth downlink time) is recorded locally without operating the message header. After receiving the downlink data message, the terminal extracts the first downlink time, the second downlink time and the third downlink time in the extended field of the IP header of the downlink data message, and summarizes the first downlink time, the second downlink time, the third downlink time and the fourth downlink time to obtain the downlink time. Optionally, in order to reduce the number of messages between the terminal and the node device, the terminal can aggregate the time information of multiple downlink data messages into one message and send it. After receiving the message, the node device performs delay statistics and time calculations to quickly locate the position of the delay anomaly. This embodiment can accurately locate the position of the delay anomaly when sending the downlink data message by aggregating all the downlink times.

[0065] In an exemplary embodiment, delay adjustment information sent by a node device is received, and delay abnormality information is adjusted according to the delay adjustment information, including: when the delay adjustment information includes 5QI, adjusting the 5QI to adjust the uplink air interface delay and / or the downlink air interface delay; when the adjusted air interface delay is less than the preset air interface delay, and the delay fluctuation of the adjusted air interface delay is greater than the preset fluctuation, receiving the adjustment strategy sent by the node device, wherein the adjustment strategy includes the delay adjustment amount, the delay deviation value between the adjusted air interface delay and the preset delay, and the adjusted air interface delay includes the adjusted uplink air interface delay and / or the adjusted downlink air interface delay; adjusting the adjusted air interface delay according to the adjustment strategy. When the air interface delay does not meet the preset delay index (for example, the service application tolerance delay threshold), the adjustment strategy of 5QI is triggered, and the preset delay index reflects the jitter of the air interface. In addition, the preset delay index can also be adjusted. For example, when the air interface delay adjustment timer times out, it is necessary to determine whether the uplink air interface delay, downlink air interface delay and end-to-end compliance rate index (the compliance rate index reflects the jitter of the end-to-end network) are in the adjustment period. If they are in the adjustment period, the preset delay index will not be adjusted, and the adjustment will be made after the next judgment of entering the stable period; if they are in the stable period and the uplink air interface delay, downlink air interface delay and compliance rate indicators do not meet the threshold requirements of the service, the adjustment of the preset delay index is triggered. The adjustment of 5QI in this embodiment is applicable to scenarios where the air interface delay and compliance rate indicators deviate greatly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0066] In an exemplary embodiment, before receiving the delay adjustment information sent by the node device and adjusting the delay abnormality information according to the delay adjustment information, the method further includes: receiving a first abnormality log collection instruction sent by the node device; responding to the first abnormality log collection instruction and collecting abnormality logs; and sending the collected first abnormality log to the node device to instruct the node device to determine the delay adjustment information according to the first abnormality log. This embodiment can quickly determine abnormal information by means of logs.

[0067] In this embodiment, a delay adjustment method is provided. Figure 4 The process of the delay adjustment method according to the embodiment of the present invention is as follows Figure 3 ,like Figure 4 The process includes the following steps:

[0068] Step S402: sending an uplink data message to a base station to instruct the base station to send uplink delay information of the uplink data message to a node device, wherein the uplink delay information includes: an uplink air interface delay between the base station and the terminal, and an uplink end-to-end delay between the terminal and the node device;

[0069] Step S404, sending the downlink delay information of the transmitted downlink data message to the node device, wherein the downlink delay information includes: the downlink air interface delay between the base station and the terminal, the downlink end-to-end delay between the terminal and the node device, and the delay adjustment information used by the node device to determine the delay anomaly information, and the delay anomaly information is determined by the node device from the uplink delay information and the downlink delay information.

[0070] The execution subject of the above steps may be a processor provided in the terminal, but is not limited thereto.

[0071] Optionally, the uplink data message includes message data and a message header, and the message header includes the time when the uplink data message is transmitted between the terminal and the base station, and the time when the uplink data message is transmitted between the base station and the node device. The downlink data message includes message data and a message header, and the message header includes the time when the downlink data message is transmitted between the base station and the node device, and the time when the downlink data message is transmitted between the base station and the terminal.

[0072] Optionally, the downlink air interface delay and the downlink end-to-end delay are determined by the time for transmitting downlink data messages between the base station and the node device and the time for transmitting downlink data messages between the base station and the terminal.

[0073] Through the above steps, since the uplink delay information and the downlink delay information are determined, the uplink delay information includes the uplink air interface delay between the base station and the terminal, and the uplink end-to-end delay between the terminal and the node device, and the downlink delay information includes the downlink air interface delay between the base station and the terminal, and the downlink end-to-end delay between the terminal and the node device, so that the end-to-end delay anomaly information can be accurately determined and the delay anomaly information can be adjusted. In this way, the end-to-end transmission delay can be guaranteed and the delay jitter can be weakened in time. Therefore, the problem that it is difficult to locate the position of the delay anomaly and the end-to-end transmission delay cannot be guaranteed in the related technology can be solved, and the position of the delay anomaly can be accurately located to ensure the effect of end-to-end transmission delay.

[0074] In an exemplary embodiment, before sending the uplink data message to the base station, the method further includes: setting the first uplink time in an extension field of a message header in the uplink data message, wherein the first uplink time is the time when the terminal sends the uplink data message. This embodiment uses the extension field to time-stamp the sending and receiving of the message, which can effectively obtain each uplink time and quickly locate the location of the delay anomaly.

[0075] In an exemplary embodiment, before sending the uplink data message to the base station, the method further includes: receiving system information broadcast by the base station, wherein the system information includes clock information of the base station; and maintaining clock synchronization with the base station according to the system information. In this embodiment, the terminal can periodically read the system information, and obtain the coordinated universal time UTC time by reading the single frequency network (SFN) data frame in the system information, so as to achieve clock synchronization and frame synchronization between the terminal and the base station.

[0076] In an exemplary embodiment, the downlink delay information of the transmitted downlink data message is sent to the node device, including: parsing the first downlink time, the second downlink time and the third downlink time from the downlink data message, wherein the first downlink time is the time when the node device sends the downlink data message, the second downlink time is the time when the base station receives the downlink data message, and the third downlink time is the air interface time when the terminal receives the downlink data message; determining the first downlink time, the second downlink time, the third downlink time and the fourth downlink time as downlink delay information, wherein the fourth downlink time is the time when the terminal decodes the IP message. For example, the first downlink time when the node device sends downlink data is entered in the IP extension header (including the extension field) of the downlink data message. The second downlink time when the base station receives the downlink data message sent by the node device is entered in the IP extension header. The third downlink time when the base station sends the downlink data message is entered in the IP extension header. The time when the terminal decodes the IP extension header (i.e., the fourth downlink time) is recorded locally without operating the message header. After receiving the downlink data message, the terminal extracts the first downlink time, the second downlink time and the third downlink time in the IP extension header of the downlink data message, and summarizes the first downlink time, the second downlink time, the third downlink time and the fourth downlink time. Optionally, in order to reduce the number of messages between the terminal and the node device, the terminal can aggregate the time information of multiple downlink data messages into one message and send it. After receiving the message, the node device performs delay statistics and time calculations to quickly locate the position of the delay anomaly. This embodiment can accurately locate the position of the delay anomaly by aggregating all the downlink times.

[0077] In an exemplary embodiment, after the downlink delay information of the transmitted downlink data message is sent to the node device, the method further includes: receiving a second abnormal log collection instruction sent by the node device; responding to the second abnormal log collection instruction, collecting abnormal logs; sending the collected second abnormal log to the node device to instruct the node device to determine the delay adjustment information according to the second abnormal log. This embodiment can quickly determine abnormal information by means of logs.

[0078] The present application is described below in conjunction with specific embodiments:

[0079] This embodiment aims at the business applications in 5G ToB or delay-sensitive scenarios that are sensitive to delay size and delay jitter, and proposes a method for measuring UE packet-level segment delay and end-to-end delay guarantee. Through SIB9 timing and NTP time and frame synchronization, the system time and air interface frame number of the terminal, base station and node engine (for example, it can be the node device mentioned above) in the system are aligned to ensure the consistency of system time of each network element in the system. It mainly includes: when the uplink data message and the downlink data message are transmitted in the network, each network element prints the timestamp of receiving and sending the uplink data message and the downlink data message in the extended field of the message header in the uplink data message and the downlink data message; the node engine extracts and summarizes the time information of the uplink data message and the downlink data message, and calculates and presents the delay index. When the delay index does not meet the service delay requirement, the node engine triggers an alarm and delimits and diagnoses the delay problem based on the segment delay index; if the air interface delay index does not meet the service delay requirement, the node engine triggers the base station to modify the 5QI or optimize the scheduling of the air interface delay to achieve end-to-end delay guarantee for service data transmission. It is convenient to achieve end-to-end UE packet-level segment delay measurement and quantification of delay indicators; when the delay index does not meet the service delay requirement, it is convenient to delimit the delay problem; when the air interface delay does not meet the requirements or the jitter exceeds the limit, the base station can be quickly notified to optimize the air interface delay to achieve the purpose of end-to-end delay guarantee for data transmission.

[0080] For example, Figure 5 As shown, each node sets the transmission time in the message header during the message transmission process. The terminal periodically reads the SIB9 system information, and obtains the UTC time of the base station clock information by reading the single frequency network (SFN) data frame in SIB9, thereby realizing the clock synchronization and frame synchronization between the terminal and the base station. When the terminal sends an uplink data message, the uplink sending time of the terminal is marked in the IP extension header of the IP message (that is, the extension field of the IP message header); when the air interface receives a downlink data message, the time of receiving the downlink air interface packet is recorded. When the IP message is decoded, the downlink packet receiving time of the IP message is recorded. All time information of the downlink data message is summarized, and the time information of the downlink data message is reported to the node engine. After receiving the abnormal log collection task, the node engine collects and reports the abnormal log.

[0081] like Figure 5As shown, the base station periodically broadcasts SIB9 system information. After receiving the NTP clock synchronization request from the node engine, it replies with the NTP clock synchronization response and periodically sends frame synchronization information to the node engine. When the base station DU receives the uplink data message sent by the terminal, it records and marks the time when the base station receives the uplink data message in the F1 GTPU extension header; after the base station CU receives the F1GTPU message, it extracts the time when the base station receives the uplink data message; when sending the NG GTPU message to the node engine, the extracted time when the base station receives the uplink data message and the time when the base station sends the uplink data message are marked in the extension header of the NG GTPU. After the base station CU receives the downlink data message from the node engine, it marks the downlink sending time of the base station in the IP extension header of the downlink data message. After receiving the abnormal log collection task, the base station collects and reports the abnormal log.

[0082] The node engine periodically sends NTP clock synchronization requests to the base station; after receiving the NTP clock synchronization response from the base station, it calculates the clock deviation and performs calibration to maintain synchronization with the base station clock. Periodically collects the frame synchronization information of the base station and extracts the frame information for air interface frame synchronization. After receiving the uplink data message sent by the base station, the time when the node engine receives the uplink data message is recorded. Extract the time when the base station receives the uplink data message and the time when the base station sends the uplink data message in the uplink NG GTPU extension header; extract the time when the terminal sends the uplink data message in the IP extension header of the uplink data message; and deliver the uplink data message to the campus server. Summarize all the time information of the uplink data message, calculate and present the delay index of the uplink data message. When receiving the downlink data message sent by the campus server, the time when the node engine sends the downlink data message is marked in the IP extension header of the downlink data message. When receiving the time information of the downlink data message reported by the terminal, extract the downlink time of the downlink data message; calculate and present the delay index of the downlink data message. When the delay index deteriorates, an alarm is triggered and the abnormal network element is notified to collect and report abnormal logs. When the air interface delay index deteriorates, the base station is triggered to modify the 5QI or fine-tune the air interface pre-scheduling to ensure the end-to-end delay requirements of data transmission.

[0083] The campus server receives uplink service data sent by the terminal device and sends downlink service data to the terminal device.

[0084] Alternatively, if Figure 6As shown, it is the process of synchronizing the system time and air interface frame number between network elements (base station, terminal, node engine) in this embodiment, and clock synchronization and frame synchronization are mainly achieved through SIB9 system information and NTP clock synchronization request. For example, the terminal periodically reads the SIB9 system information, obtains the base station clock, and keeps the clock of the terminal and the base station synchronized. The format of the SIB9 system information message includes a message format based on the 38.331 protocol. For another example, the node engine periodically sends an NTP clock synchronization request to the base station, waits for and receives an NTP clock synchronization response; calculates the clock deviation and calibrates the clock of the node engine. The node engine periodically receives the frame synchronization signal of the base station, reads the frame number and subframe number to keep the node engine and the base station air interface frame number aligned.

[0085] Optionally, this embodiment also includes recording the delay by time stamping when sending and receiving uplink data messages and downlink data messages. For example, the time stamp of the uplink data message mainly includes the timestamp T4 when the terminal sends the uplink data message, the timestamp T3 when the base station receives the uplink data message sent by the terminal, the timestamp T2 when the base station receives the downlink data message sent by the node engine, and the timestamp T1 when the node engine receives the uplink data message sent by the base station. Figure 7 As shown, T4: the time point when the terminal sends the uplink data message, which is entered in the IP extension header (extension field of the IP header) of the uplink data message. T3: the time point when the base station DU receives the uplink data message sent by the terminal, which is entered in the F1 GTPU extension header. T2: the time point when the base station CU receives the downlink data message from the node engine. When the base station CU sends the NG GTPU message, it enters T3 and T2 in the NGGTPU extension header. T1: the time point when the node engine receives the uplink data message sent by the base station, which is recorded locally without operating the message header. The node engine data transceiver module extracts the T2 and T3 times of the NG GTPU extension header, solves the T4 of the IP header extension field of the data message, summarizes the T1, T2, T3, and T4 times and submits them to the delay statistics module in the node engine. The delay statistics module performs delay calculation and delay index calculation and delay judgment.

[0086] Optionally, the time stamp of the downlink data message mainly includes the time point T1' when the node engine sends the downlink data message, the time T2' when the base station CU receives the downlink data message from the node engine, the air interface time T3' when the terminal receives the downlink data message, and the time T4' when the terminal decodes the IP message. Figure 7As shown, T1': the time point when the node engine sends the downlink data message, which is included in the IP extension header of the downlink data message. T2': the time when the base station CU receives the downlink data message from the node engine, which is included in the IP extension header of the downlink data message. T3': the air interface time when the terminal receives the downlink data message, which is recorded locally without operating the message header. T4': the time when the terminal decodes the IP message, which is recorded locally without operating the message header. After the terminal receives the uplink data message, it extracts T1' and T2' from the IP extension header of the downlink data message, and summarizes T1', T2', T3', and T4' times; in order to reduce the number of messages between the terminal and the node engine, the terminal can aggregate the time information of multiple messages into one message and send it. After the node engine receives the message, the delay statistics module performs delay calculation, delay index calculation, and delay judgment.

[0087] Optionally, the format of the IP extension header is as follows Figure 8 As shown, the uplink terminal adds 4 bytes to the IP extension header to store T4. The downlink node engine adds 8 bytes to the IP extension header, the first 4 bytes are used to store T1', and the last 4 bytes are reserved for base station T2'.

[0088] Optionally, the format of the GTPU extension header is as follows Fig. 9 As shown, for data packets transmitted in the uplink direction by the base station, a GTPU extension header needs to be used to store the time point.

[0089] Alternatively, if Fig.10 As shown, it is a schematic diagram of the time definition of the extended header of the F1 GTPU uplink data message. The uplink F1 GTPU extended header is used to fill in the time point T3 when the base station DU receives the uplink data message sent by the terminal.

[0090] Optionally, the time definition of the extension header of the NG GTPU uplink data message is as follows: Fig.11 As shown, the uplink NGGTPU extension header is used to fill in the time point T3 when the base station DU receives the uplink data message sent by the terminal and the time point T2 when the base station CU receives the downlink data message from the node engine.

[0091] Optionally, since the base station and the terminal need to encrypt and secure the IP extension header when sending air interface data, the IP extension header cannot be operated when sending data, resulting in the loss of the corresponding timestamp. However, since the internal processing delays of the base station and the terminal are relatively stable and have corresponding statistics, the internal processing delay of the terminal is calculated into the uplink air interface delay in the uplink direction, and the internal processing delay of the base station is calculated into the downlink air interface delay in the downlink direction. Combined with the time points obtained above, the NG GTPU extension header delay indicator is as follows: Fig.12 As shown, specifically including:

[0092] Uplink end-to-end delay: the time interval from when the IP extension header is sent from the terminal to when it is received by the node engine, T1-T4;

[0093] Downlink end-to-end delay: the time interval from when the IP extension header is sent from the node engine to when it is received by the terminal, T4'-T1';

[0094] Uplink air interface delay: the time interval from the IP extension header being sent from the terminal to the air interface base station DU being received, T3-T4;

[0095] Downlink air interface delay: the time interval from when the base station CU receives the IP extension header to when the air interface terminal receives it, T3'-T2';

[0096] Uplink base station internal processing delay: the time interval from the air interface base station DU receiving the IP extension header to the base station CU sending the IP extension header, T2-T3;

[0097] Downlink terminal internal processing delay: the time interval from the base station CU receiving the IP extension header to the air interface terminal receiving the IP extension header, T4'-T3'.

[0098] For example, the calculation of the delay between each node specifically includes the following:

[0099] Calculate the end-to-end delay average: the average value of the end-to-end delay within the statistical period (uplink data message transmission or downlink data message transmission), which can reflect the service quality of the network between nodes;

[0100] Calculate the end-to-end delay compliance rate: the ratio of the number of times the end-to-end delay is less than the tolerance delay threshold of the service application within the statistical period (uplink data packet transmission or downlink data packet transmission) to the statistical number of times, which can reflect the jitter of the network between nodes;

[0101] Calculate the maximum and minimum end-to-end delay: the maximum and minimum end-to-end delay within the statistical period (uplink data packet transmission or downlink data packet transmission);

[0102] Calculate the average air interface delay: The average air interface delay within the statistical period (uplink data message transmission or downlink data message transmission) can reflect the air interface quality between nodes;

[0103] Calculate the air interface delay compliance rate: the ratio of the number of times the air interface delay is less than the service application tolerance delay threshold to the statistical number of times within the statistical period (uplink data packet transmission or downlink data packet transmission) can reflect the jitter of the air interface between nodes;

[0104] Calculate the maximum and minimum values ​​of the air interface delay: the maximum and minimum values ​​of the air interface delay within the statistical period (uplink data packet transmission or downlink data packet transmission).

[0105] For example, Fig.13 As shown, the node engine calculates the delay index by the following steps:

[0106] S1301, waiting for the time report message of the uplink data message and the downlink data message;

[0107] S1302, receiving the time report message of the uplink data message and the downlink data message

[0108] S1303, determining whether the time point in the time reporting message is valid;

[0109] S1304, when the time point is valid, calculating the end-to-end and segment delays of the uplink data message and the downlink data message (such as the various time points in the above embodiment);

[0110] S1305, update the delay indicators and the standard-reaching rate delay of the uplink data message and the downlink data message according to the calculated segment delay, and end this operation after updating the delay indicators and the standard-reaching rate delay of the uplink data message and the downlink data message, otherwise go to S1301 and execute the above steps in a loop.

[0111] Optionally, the air interface quality judgment and delay indicator adjustment strategy in this embodiment includes the following contents:

[0112] Due to the mobility of the terminal, the air interface channel quality is uncertain, and there is a large uncertainty in the air interface delay and delay jitter. In a real network, the uncertainty of air interface delay has a great impact on the end-to-end delay and jitter of service data. When the uplink and downlink air interface delay and compliance rate indicators deviate from the tolerance range of the service application within the statistical period, the node engine starts the 5QI adjustment or air interface delay scheduling optimization strategy to ensure the delay requirements of the service application.

[0113] For example, the air interface quality judgment and adjustment process is as follows Fig.14 As shown, the following steps are included:

[0114] S1401, waiting for the periodic air interface delay adjustment timer to time out;

[0115] S1402, air interface delay adjustment timer times out;

[0116] S1403, determining whether the air interface delay indicator and the target achievement rate indicator are in the adjustment period; if they are in the adjustment period, the air interface delay indicator is not adjusted, and the adjustment is made after the next determination that the air interface delay indicator enters the stable period;

[0117] S1404: If the adjustment period is not in progress, determine whether the air interface delay index and the compliance rate meet the service delay threshold requirement;

[0118] S1405: If the delay and compliance rate indicators do not meet the threshold requirements of the service in the stable period, the delay indicator adjustment is triggered, and the 5QI is reselected according to the delay requirements and the base station is triggered to perform the 5QI modification to optimize the air interface delay; and it is determined whether the QoS delay of the current 5QI meets the expected delay requirements;

[0119] S1406, when the QoS delay of the current 5QI does not meet the expected delay requirement, obtain a 5QI that meets the expected delay requirement;

[0120] S1407, determining whether the 5QI required by the expected delay is valid;

[0121] S1408, when the 5QI of the expected delay requirement is valid, notify the base station to adjust the 5QI of the expected delay requirement;

[0122] S1409, waiting for the base station to respond to the adjustment of the 5QI. If the base station responds to the adjustment of the 5QI, the adjustment operation is terminated. If the base station does not respond to the adjustment of the 5QI, the process returns to S1401 and the above steps are repeated.

[0123] S1410, when the QoS delay of the current 5QI meets the expected delay requirement, calculate the deviation and adjustment amount between the current actual delay and the compliance rate and the expected value;

[0124] S1411: If the current 5QI meets the service application delay requirements, but the air interface delay and compliance rate indicators still fluctuate and affect the service delay requirements, start air interface delay scheduling optimization to ensure the QoS delay requirements.

[0125] Optionally, the reselection strategy and adjustment of 5QI include the following:

[0126] When the air interface delay and compliance rate indicators deviate from the service application tolerance delay threshold and the current 5QIQoS delay does not meet the service delay requirements, the 5QI reselection strategy is triggered. The node engine statically selects 5QI or dynamically matches 5QI according to the delay requirements of the service application, finds the 5QI that meets the service delay requirements, and triggers the base station to perform 5QI modification; the base station remaps DRB and accepts resources according to the newly configured 5QI, triggers the adjustment of scheduling priority, and ensures the air interface delay requirements. The adjustment of 5QI is applicable to scenarios where the air interface delay and compliance rate indicators deviate greatly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0127] For example, the process of 5QI reselection strategy is as follows Fig.15 As shown, the following steps are included:

[0128] S1501, obtaining a 5QI that meets the expected delay requirement;

[0129] S1502, determining whether the transmitted service is configured with a static 5QI;

[0130] S1503, when a static 5QI is configured, read the corresponding static 5QI from the static configuration table, and return the configured static 5QI;

[0131] S1504, when a static 5QI is not configured, read all 5QIs and configurations of the current same service type from the 5QI configuration table;

[0132] S1505, filtering out 5QIs whose packet delay is greater than the expected packet delay;

[0133] S1506, filtering out 5QIs whose packet loss rate is greater than the expected packet loss rate;

[0134] S1507, filtering out 5QIs whose rates are lower than the expected rate;

[0135] S1508, filtering out 5QIs whose maximum data burst volume is less than the expected maximum data burst volume;

[0136] S1509, determining whether the filtered 5QI list is empty;

[0137] S1510, when the 5QI list is empty, returning an invalid 5QI;

[0138] S1511, when the 5QI list is not empty, the 5QI list is sorted in descending order according to packet delay;

[0139] S1512, return the first 5QI in the list.

[0140] Optionally, the air interface delay scheduling optimization strategy in this embodiment specifically includes the following contents:

[0141] If the current 5QIQoS delay meets the service delay requirements, but the air interface delay and compliance rate indicators still fluctuate and affect the service delay requirements, the air interface delay scheduling optimization strategy is started. The node engine calculates the deviation and adjustment amount between the current delay and compliance rate and the service expected delay and compliance rate, and triggers the base station to perform air interface delay scheduling optimization. The base station adjusts the QoS parameter PDB value and retransmission failure rate according to the adjustment amount, remaps the HARQ transmission times and target BLER, and recalculates the scheduling strategy and scheduling priority to ensure the QoS delay requirements.
