[0037] The method embodiments provided in the embodiments of the present disclosure can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, FIG1 is a hardware structure block diagram of a mobile terminal of a delay adjustment method of an embodiment of the present disclosure. As shown in FIG1 , the mobile terminal may include one or more (only one is shown in FIG1 ) processors 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 configured to store data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 configured to have a communication function.

For example, the mobile terminal may also include more or fewer components than those shown in FIG1 , or have a configuration different from that shown in FIG1 .

[0038] The memory 104 can be configured to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the delay adjustment method in the embodiment of the present disclosure. 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-mentioned 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 located relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network.

[0039] The transmission device 106 is configured to receive or transmit data via a network.

In one embodiment, the transmission device 106 may be a radio frequency (RF) module configured to communicate with the Internet wirelessly.

[0040] In this embodiment, a delay adjustment method is provided. FIG2 is a flowchart of the delay adjustment method according to an embodiment of the present disclosure. As shown in FIG2 , the process includes the following steps:

[0041] 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;

[0042] Step S204: determining downlink delay information for transmitting the downlink data message, 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;

[0043] 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.

[0044] 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 that performs message transmission with the terminal and the base station.

[0045] 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.

[0046] Optionally, the preset latency indicator can be set according to different application scenarios, such as the latency between a base station and a terminal, or the latency between a terminal and a node device. Different application scenarios require different latency. This indicator is primarily used to compare with the latency in the uplink and downlink latency information to determine whether a latency anomaly has occurred.

[0047] Through the above steps, since the uplink delay information and 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 and the effect of ensuring the end-to-end transmission delay can be achieved.

[0048] 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; using the first uplink time and the fourth uplink time to determine the uplink end-to-end delay, wherein the fourth uplink time is the time when the node device receives the uplink data message; using the first uplink time, the second uplink time, and the processing time of the uplink data message by the base station to determine the uplink air interface delay, 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; and 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 the various times 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 location of the abnormal delay can be located.

[0049] 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 to judge the abnormal delay information. This embodiment uses the extended field to time-stamp the sending and receiving of uplink messages, which can effectively obtain each uplink time and quickly locate the position of the delay anomaly.

[0050] In one exemplary embodiment, determining downlink delay information for transmitting a downlink data packet includes: parsing a downlink time sent by a terminal to determine a first downlink time, a second downlink time, and a third downlink time, wherein the first downlink time is the time when the node device sends the downlink data packet, the second downlink time is the time when the base station receives the downlink data packet, and the third downlink time is the air interface time when the terminal receives the downlink data packet; determining a downlink end-to-end delay using the first downlink time and the fourth downlink time, wherein the fourth downlink time is the time when the terminal decodes the IP packet; determining a downlink air interface delay using the second downlink time and the third downlink time; determining an internal processing time of the terminal using the third downlink time and the fourth downlink time; and determining the downlink end-to-end delay, the downlink air interface delay, and the processing time of the downlink data packet 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 an extension field of a message header in the downlink data message. For example, the first downlink time when the node device sends downlink data is included 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 is received by the base station and is entered into 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 into the IP extension header of the downlink data message. The terminal records the fourth downlink time obtained by decrypting the IP extension header locally at 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 from the IP extension header in 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 multiple downlink time information into one message and send it. 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.

[0051] In an exemplary embodiment, before determining the uplink delay information for transmitting an uplink data message, the method further includes: sending a clock synchronization request to a 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, sending 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.

[0052] In an exemplary embodiment, delay anomaly information is determined from the uplink delay information and the downlink delay information based on a preset delay indicator, and the delay anomaly information is adjusted, including: when the uplink air interface delay is greater than a first preset delay, and / or the downlink air interface delay is greater than a second preset delay, initiating adjustment of the 5G service quality flow identifier 5QI to determine delay adjustment information, wherein the preset delay indicator includes a first preset delay and a second preset delay; and adjusting the delay anomaly information using the delay adjustment information. In this embodiment, when the air interface delay does not meet the preset delay indicator (for example, the service application tolerance delay threshold), the 5QI adjustment strategy is triggered, and the preset delay indicator 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 index 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 significantly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0053] 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: 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 5QI QoS 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 the 5QI that meets the service delay requirements, and triggers the base station to perform 5QI modification. The adjustment of 5QI in this embodiment is applicable to scenarios where the air interface delay and compliance rate indicators deviate significantly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0054] 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 the air interface delay adjustment amount, the delay deviation value between the adjusted air interface delay and the preset air interface delay, and the adjusted air interface delay includes the adjusted uplink air interface delay and / or the adjusted downlink air interface delay; 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 5QI QoS delay meets service delay requirements, but air interface delay and delay compliance rate indicators still fluctuate and affect service delay requirements, the air interface delay scheduling optimization strategy is activated. 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, triggering the base station to perform air interface delay scheduling optimization. The base station adjusts the QoS parameter PDB value and retransmission failure rate based on the adjustment amount, remaps the HARQ transmission times and target BLER, and recalculates the scheduling strategy and scheduling priority to ensure QoS delay requirements.

[0055] In an exemplary embodiment, before determining the delay anomaly information from the uplink delay information and the downlink delay information according to the preset delay index and adjusting the delay anomaly information, the above method further 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 delay anomaly 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 delay anomaly information. This embodiment can quickly determine abnormal information by means of logs.

[0056] In this embodiment, a delay adjustment method is provided. FIG3 is a second flowchart of the delay adjustment method according to an embodiment of the present disclosure. As shown in FIG3 , the process includes the following steps:

[0057] Step S302: Sending uplink delay information of the transmitted uplink data message to the node device, 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;

[0058] Step S304: Send the downlink data message to the terminal to instruct the terminal to send downlink delay information of the downlink data message to the node device, where 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;

[0059] Step S306: Receive the delay adjustment information sent by the node device, and adjust 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.

[0060] The execution entity of the above steps may be a base station, but is not limited thereto.

[0061] 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.

[0062] 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.

[0063] Through the above steps, since the uplink delay information and 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 and the effect of ensuring the end-to-end transmission delay can be achieved.

[0064] In an exemplary embodiment, before sending the uplink delay information of the transmitted uplink data packet to the node device, the method further includes: receiving an uplink data packet sent by a terminal, wherein the extension field of the message header of the uplink data packet includes a first uplink time; and setting both a second uplink time and a third uplink time in the extension field of the message header of the uplink data packet, wherein the second uplink time is the time when the base station receives the uplink data packet, and the third uplink time is the time when the base station transmits the uplink data packet. 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 packet sent by the terminal is included in the IP extension header (including the extension field) of the uplink data packet. The second uplink time of the uplink data packet received by the terminal and the third uplink time of the uplink data packet sent by the base station to the node device are included in the GTPU extension header (including the extension field) of the uplink data packet. The node device receives the fourth uplink time of the uplink data packet sent by the base station and records it locally on the node device without manipulating the message header. The node device extracts the first uplink time from the IP extension header of the uplink data message, extracts the second and third uplink times from the GTPU extension header of the uplink data message, and, combined with the fourth uplink time, aggregates the uplink times and performs delay statistics and delay calculations to determine abnormal delay information. This embodiment uses the extended field to time-stamp the transmission and reception of uplink messages, effectively obtaining each uplink time and quickly locating the location of the delay anomaly.

[0065] In an exemplary embodiment, before sending the uplink delay information of the transmitted uplink data packet 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 Coordinated Universal Time (UTC) by reading Single Frequency Network (SFN) data frames in the system information, thereby achieving clock synchronization and frame synchronization between the terminal and the base station.

[0066] 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 maintain synchronization with the base station clock. The node device periodically receives the frame synchronization signal of the base station, reads the frame number and subframe number, and can also maintain the alignment of the air interface frame number of the node device and the base station.

[0067] 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 of the downlink data message includes a first downlink time and a second downlink time, the first downlink time being the time when the node device sends the downlink data message, and the second downlink time being the time when the base station receives the downlink data message; and setting a third downlink time in the extension field of the message header of 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 of the downlink data message. For example, the first downlink time when the node device sends downlink data is included 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 included in the IP extension header of the data message. The third downlink time when the base station sends the downlink data message is included in the IP extension header of the data message. The terminal decodes the time of the IP extension header (i.e., the fourth downlink time) and records it locally without manipulating 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.

[0068] In an exemplary embodiment, delay adjustment information sent by a node device is received, and delay anomaly 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 an adjustment strategy sent by the node device, wherein the adjustment strategy includes a delay adjustment amount, a 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; and 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 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 index 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 significantly from the threshold, and can quickly adjust the air interface delay to a certain range.

[0069] In an exemplary embodiment, before receiving the delay adjustment information sent by the node device and adjusting the delay anomaly information according to the delay adjustment information, the method further includes: receiving a first anomaly log collection instruction sent by the node device; responding to the first anomaly log collection instruction and collecting the anomaly log; and sending the collected first anomaly log to the node device to instruct the node device to determine the delay adjustment information according to the first anomaly log. This embodiment can quickly determine anomaly information through logs.

[0070] In this embodiment, a delay adjustment method is provided. FIG4 is a flowchart of the delay adjustment method according to an embodiment of the present disclosure. As shown in FIG4 , the process includes the following steps:

[0071] Step S402: Send an uplink data message to the base station to instruct the base station to send uplink delay information of the uplink data message to the node device, where 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;

[0072] Step S404: Send the downlink delay information of the transmitted downlink data message to the node device, where 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 set by the node device to determine the delay anomaly information. The delay anomaly information is determined by the node device from the uplink delay information and the downlink delay information.

[0073] The execution subject of the above steps may be a processor provided in the terminal, but is not limited thereto.

[0074] 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.

[0075] 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.

[0076] Through the above steps, since the uplink delay information and 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 and the effect of ensuring the end-to-end transmission delay can be achieved.

[0077] In an exemplary embodiment, before sending the uplink data message to the base station, the method further includes: setting a first uplink time in an extension field of a message header in the uplink data message, where 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 transmission and reception of messages, effectively obtaining each uplink time and quickly locating the location of the delay anomaly.

[0078] 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 Coordinated Universal Time (UTC) by reading the Single Frequency Network (SFN) data frames in the system information, thereby achieving clock and frame synchronization between the terminal and the base station.

[0079] In one exemplary embodiment, sending downlink delay information of a transmitted downlink data packet to a node device includes: parsing the downlink data packet to determine a first downlink time, a second downlink time, and a third downlink time, wherein the first downlink time is the time when the node device sends the downlink data packet, the second downlink time is the time when the base station receives the downlink data packet, and the third downlink time is the air interface time when the terminal receives the downlink data packet; and 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 packet. For example, the first downlink time when the node device sends downlink data is included in the IP extension header (including the extension field) of the downlink data packet. The second downlink time when the base station receives the downlink data packet sent by the node device is included in the IP extension header. The third downlink time when the base station sends the downlink data packet is included 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 requiring any header manipulation. After receiving the downlink data message, the terminal extracts the first downlink time, the second downlink time, and the third downlink time from 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 location of the delay anomaly. This embodiment can accurately locate the location of the delay anomaly by aggregating all downlink times.

[0080] In an exemplary embodiment, after transmitting the downlink delay information of the transmitted downlink data packet to the node device, the method further includes: receiving a second abnormality log collection instruction from the node device; responding to the second abnormality log collection instruction and collecting the abnormality log; and transmitting the collected second abnormality log to the node device to instruct the node device to determine the delay adjustment information based on the second abnormality log. This embodiment can quickly determine abnormal information through logs.

[0081] The present disclosure is described below with reference to specific embodiments:

[0082] This embodiment aims at the fact that business applications in 5G ToB or delay-sensitive scenarios are more 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 the 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 of 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, calculates and presents the delay index. When the latency indicator does not meet the service latency requirement, the node engine triggers an alarm and demarcates and diagnoses the latency issue based on the segmented latency indicator. If the air interface latency indicator does not meet the service latency requirement, the node engine triggers the base station to modify the 5QI or optimize the air interface latency scheduling to achieve end-to-end latency guarantee for service data transmission. This facilitates end-to-end UE packet-level segmented latency measurement and latency indicator quantification. When the latency indicator does not meet the service latency requirement, it facilitates demarcation of the latency issue. When the air interface latency does not meet the requirement or jitter exceeds the limit, the base station can be quickly notified to optimize the air interface latency, achieving the goal of end-to-end latency guarantee for data transmission.

[0083] For example, as shown in Figure 5, 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's clock information by reading the single frequency network (SFN) data frame in the SIB9, thereby achieving clock synchronization and frame synchronization between the terminal and the base station. When the terminal sends an uplink data message, it marks the uplink sending time of the terminal 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, it records the time when the downlink air interface receives the packet. When the IP message is decoded, the downlink packet reception time of the IP message is recorded. Summarize all the time information of the downlink data message and report the time information of the downlink data message to the node engine. After receiving the abnormal log collection task, the node engine collects and reports the abnormal log.

[0084] As shown in Figure 5, the base station periodically broadcasts SIB9 system information. After receiving an NTP clock synchronization request from the node engine, it responds with an NTP clock synchronization response and periodically sends frame synchronization information to the node engine. When the base station DU receives an uplink data packet from a terminal, it records and adds the time the base station received the uplink data packet to the F1 GTPU extension header. After receiving the F1 GTPU message, the base station CU extracts the time the base station received the uplink data packet. When sending an NG GTPU message to the node engine, the extracted time the base station received the uplink data packet and the time the base station sent the uplink data packet are added to the NG GTPU extension header. After receiving a downlink data packet from the node engine, the base station CU adds the base station's downlink sending time to the IP extension header of the downlink data packet. Upon receiving an exception log collection task, the base station collects and reports the exception log.

[0085] The node engine periodically sends NTP clock synchronization requests to the base station. After receiving the base station's NTP clock synchronization response, it calculates and calibrates the clock offset to maintain synchronization with the base station's clock. It periodically receives frame synchronization information from the base station and extracts the frame information for air interface frame synchronization. Upon receiving an uplink data packet from the base station, the node engine records the time the uplink data packet was received. It extracts the time the base station received the uplink data packet and the time the base station sent the uplink data packet from the uplink NG GTPU extension header. It also extracts the time the terminal sent the uplink data packet from the IP extension header within the uplink data packet. The node engine then delivers the uplink data packet to the campus server. It aggregates all time information from the uplink data packet and calculates and presents the latency metrics for the uplink data packet. Upon receiving a downlink data packet from the campus server, it adds the time the node engine sent the downlink data packet to the IP extension header of the downlink data packet. Upon receiving the time information for the downlink data packet reported by the terminal, it extracts the downlink time of the downlink data packet and calculates and presents the latency metrics for the downlink data packet. When latency indicators deteriorate, an alarm is triggered and the abnormal network element is notified to collect and report abnormal logs. When the air interface latency indicator deteriorates, the base station is triggered to modify the 5QI or fine-tune the air interface pre-scheduling to ensure the end-to-end latency requirements of data transmission.

[0086] The campus server receives uplink service data from terminal devices and sends downlink service data to the terminal devices.

[0087] Optionally, as shown in Figure 6, this is the process of synchronizing the system time and air interface frame number between network elements (base station, terminal, node engine) in this embodiment, mainly realizing clock synchronization and frame synchronization 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 clocks 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 air interface frame number of the node engine and the base station aligned.

[0088] Optionally, this embodiment also includes recording the time delay by time stamping when sending and receiving uplink and downlink data packets. For example, the time stamp of the uplink data packet mainly includes the timestamp T4 when the terminal sends the uplink data packet, the timestamp T3 when the base station receives the uplink data packet sent by the terminal, the timestamp T2 when the base station receives the downlink data packet sent by the node engine, and the timestamp T1 when the node engine receives the uplink data packet sent by the base station. As shown in Figure 7, T4: the time point when the terminal sends the uplink data packet, which is stamped in the IP extension header (extension field of the IP header) of the uplink data packet. T3: the time point when the base station DU receives the uplink data packet sent by the terminal, which is stamped in the F1 GTPU extension header. T2: the time point when the base station CU receives the downlink data packet from the node engine. When the base station CU sends the NG GTPU packet, T3 and T2 are stamped in the NG GTPU extension header. T1: the time point when the node engine receives the uplink data packet sent by the base station, which is recorded locally without the need to manipulate the packet header. The node engine data transceiver module extracts the T2 and T3 times from the NG GTPU extension header, extracts the T4 field from the data packet IP header extension field, summarizes the T1, T2, T3, and T4 times, and submits them to the delay statistics module in the node engine. The delay statistics module calculates the delay, calculates the delay index, and makes delay judgments.

[0089] Optionally, the downlink data message timestamp primarily includes the time 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. For example, as shown in Figure 7, T1′ is the time the node engine sends the downlink data message, which is stamped in the IP extension header of the downlink data message. T2′ is the time the base station CU receives the downlink data message from the node engine, which is stamped in the IP extension header of the downlink data message. T3′ is the air interface time when the terminal receives the downlink data message, which is recorded locally without header manipulation. T4′ is the time when the terminal decodes the IP message, which is recorded locally without header manipulation. After receiving the uplink data message, the terminal extracts T1′ and T2′ from the IP extension header of the downlink data message and aggregates T1′, T2′, T3′, and T4′. To reduce the number of messages between the terminal and the node engine, the terminal can aggregate the time information of multiple messages into a single message. After the node engine receives the message, the delay statistics module performs delay calculation, delay index calculation and delay judgment.

[0090] Alternatively, the format of the IP extension header is shown in Figure 8. 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, with the first 4 bytes used to store T1' and the last 4 bytes reserved for base station T2'.

[0091] Optionally, the format of the GTPU extension header is shown in FIG9 . For data packets transmitted in the uplink direction by the base station, the GTPU extension header needs to be used to store the time point.

[0092] Optionally, as shown in FIG10 , which 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.

[0093] Optionally, the time definition of the extended header of the NG GTPU uplink data message is shown in Figure 11. The uplink NG 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 and the time point T2 when the base station CU receives the downlink data message from the node engine.

[0094] Optionally, since the base station and 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 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 indicators are shown in Figure 12, specifically including:

[0095] 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;

[0096] 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′;

[0097] 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;

[0098] 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′;

[0099] 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;

[0100] 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′.

[0101] For example, the calculation of the delay between each node specifically includes the following:

[0102] Calculate the average end-to-end delay: The average end-to-end delay within the statistical period (uplink data packet transmission or downlink data packet transmission) can reflect the service quality of the network between nodes;

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

[0104] 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);

[0105] Calculate the average air interface delay: The average air interface delay within the statistical period (uplink data packet transmission or downlink data packet transmission) can reflect the air interface quality between nodes;

[0106] 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 during the statistical period (uplink data packet transmission or downlink data packet transmission) to the statistical number of times can reflect the jitter of the air interface between nodes;

[0107] Calculate the maximum and minimum air interface delay values: the maximum and minimum air interface delay values ​​within the statistical period (uplink data packet transmission or downlink data packet transmission).

[0108] For another example, as shown in FIG13 , the node engine performs a latency indicator calculation process including the following steps:

[0109] S1301, waiting for time reporting messages of uplink data packets and downlink data packets;

[0110] S1302, receiving a time report message of an uplink data message and a downlink data message;

[0111] S1303, determining whether the time point in the time report message is valid;

[0112] S1304: If the time point is valid, calculate 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);

[0113] S1305: Update the delay indicators and target-reaching rate delays of the uplink and downlink data packets according to the calculated segment delays. End this operation after the delay indicators and target-reaching rate delays of the uplink and downlink data packets are updated. Otherwise, go to S1301 and loop through the above steps.

[0114] Optionally, the air interface quality judgment and delay indicator adjustment strategy in this embodiment includes the following:

[0115] Due to the mobility of terminals, there is uncertainty in the air interface channel quality, resulting in significant uncertainty in air interface delay and delay jitter. In real networks, the uncertainty of air interface delay has a significant 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 initiates 5QI adjustment or air interface delay scheduling optimization strategy to meet the delay requirements of the service application.

[0116] For example, the air interface quality judgment and adjustment process is shown in Figure 14, which includes the following steps:

[0117] S1401, waiting for the periodic air interface delay adjustment timer to time out;

[0118] S1402, the air interface delay adjustment timer times out;

[0119] S1403, determining whether the air interface delay indicator and the compliance rate indicator are in the adjustment period; if they are in the adjustment period, no adjustment is made to the air interface delay indicator, and adjustment is made again after the next stable period is determined;

[0120] S1404: If the service is not in the adjustment period, determine whether the air interface delay indicator and the compliance rate meet the service delay threshold requirement;

[0121] S1405: If the service is in a stable period and the latency and compliance rate indicators do not meet the service threshold requirements, a latency indicator adjustment is triggered. The 5QI is reselected based on the latency requirements and the base station is triggered to modify the 5QI to optimize the air interface latency. The QoS latency of the current 5QI is determined to meet the expected latency requirements.

[0122] 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;

[0123] S1407, determining whether the 5QI required by the expected delay is valid;

[0124] S1408: When the 5QI of the expected delay requirement is valid, notify the base station to adjust the 5QI of the expected delay requirement;

[0125] 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 repeats the above steps.

[0126] S1410, when the current 5QI QoS delay meets the expected delay requirement, calculate the deviation and adjustment amount between the current actual delay and compliance rate and the expected value;

[0127] S1411: If the current 5QI meets the service application delay requirement, but the air interface delay and compliance rate indicators still fluctuate and affect the service delay requirement, start air interface delay scheduling optimization to ensure the QoS delay requirement.

[0128] Optionally, the 5QI reselection strategy and adjustment include the following:

[0129] When the air interface delay and compliance rate indicators deviate from the service application's tolerance delay threshold and the current 5QI QoS delay does not meet the service delay requirements, the 5QI reselection strategy is triggered. The node engine statically selects a 5QI based on the service application's delay requirements or dynamically matches a 5QI. Finding a 5QI that meets the service delay requirements triggers the base station to modify the 5QI. The base station remaps DRBs and reaccepts resources based on the newly configured 5QI, triggering scheduling priority adjustments to ensure air interface delay requirements. 5QI adjustment is applicable to scenarios where the air interface delay and compliance rate indicators deviate significantly from the threshold and can quickly adjust the air interface delay to a certain range.

[0130] For example, the process of the 5QI reselection strategy is shown in Figure 15, which includes the following steps:

[0131] S1501, obtaining a 5QI that meets the expected delay requirement;

[0132] S1502, determining whether the transmitted service is configured with a static 5QI;

[0133] S1503: If a static 5QI is configured, read the corresponding static 5QI from the static configuration table and return the configured static 5QI;

[0134] S1504: If no static 5QI is configured, all 5QIs and configurations of the current service type are read from the 5QI configuration table;

[0135] S1505: Filter out 5QI packets whose delay is greater than the expected delay.

[0136] S1506, filtering out 5QIs whose packet loss rate is greater than the expected packet loss rate;

[0137] S1507, filtering out 5QIs whose rates are lower than the expected rate;

[0138] S1508, filtering out 5QIs whose maximum data burst volume is less than the expected maximum data burst volume;

[0139] S1509, determining whether the filtered 50I list is empty;

[0140] S1510: If the 5QI list is empty, return an invalid 5QI;

[0141] S1511: If the 5QI list is not empty, the 5QI list is sorted in descending order of packet delay;

[0142] S1512, return the first 5QI in the list.

[0143] Optionally, the air interface delay scheduling optimization strategy in this embodiment specifically includes the following contents:

[0144] If the current 5QI QoS delay meets service delay requirements, but air interface delay and compliance rate indicators still fluctuate and affect service delay requirements, the air interface delay scheduling optimization strategy is initiated. The node engine calculates the deviation and adjustment amount between the current delay and compliance rate and the service's expected delay and compliance rate, triggering the base station to perform air interface delay scheduling optimization. Based on the adjustment amount, the base station adjusts the QoS parameter PDB value and retransmission failure rate, remaps the HARQ transmission times and target BLER, and recalculates the scheduling strategy and scheduling priority to ensure QoS delay requirements.

[0145] To summarize, this embodiment targets 5G ToB or delay-sensitive scenarios. Through an end-to-end delay guarantee solution based on the measurement of UE packet-level segment delay, it is possible to quickly measure the UE packet-level segment delay and locate the delay problem, thereby quickly achieving end-to-end delay guarantee for service messages.
