Description

Technical Field

[0001] The present disclosure relates to the field of satellite communication technology or aerospace communication technology, and particularly to a communication method, apparatus, storage medium, and electronic device. Background Art

[0002] In the field of satellite communication, data transmission between a satellite and a ground station is a core link in the satellite control process. With the rapid development of aerospace technology, satellites are playing an increasingly important role in multiple fields such as remote sensing, navigation, and communication. However, the communication environment between a satellite and a ground station has its particularities, such as long distance, large signal attenuation, and susceptibility to interference, which pose extremely high requirements for the integrity and reliability of communication.

[0003] Currently, satellite-ground TT&C communication usually adopts an unreliable connection method, that is, after the sender sends data, the receiver does not verify or confirm the reception status of the data. Although this communication method is relatively simple to implement, it cannot guarantee the integrity of the data. During the transmission process, the data may be lost or incorrect due to various reasons (such as signal interference, equipment failure, etc.), and the receiver cannot know this situation, resulting in unreliable data transmission.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part rather than all of the embodiments of the present disclosure. Components of the embodiments of the present disclosure generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the detailed description of the embodiments of the present disclosure provided herein is not intended to limit the scope of the claimed present disclosure, but merely represents selected embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0023] As described in the background art section, the inventors found that there is a problem that the data integrity of the existing satellite-ground measurement and control communication method cannot be guaranteed. Specifically, the existing satellite-ground measurement and control communication usually uses an unreliable connection, and the receiving party does not verify the data reception situation of the sending party.

[0024] In addition, the inventors also found that if the existing reliable communication protocol, such as the TCP (Transmission Control Protocol) protocol, is adopted, many challenges will be faced. On the one hand, the satellite communication environment has characteristics such as high latency and high bit error rate, which makes the acknowledgment and retransmission mechanisms of the TCP protocol may become very inefficient; on the other hand, the computing and storage resources of the satellite and the ground station are relatively limited, and the implementation of the TCP protocol requires a certain amount of computing and storage overhead, which may be too complex for the satellite-ground side.

[0025] The embodiments of the present disclosure provide a communication method, device, storage medium and electronic device, which can adapt to the particularity of the satellite communication environment and ensure the reliable transmission of satellite-ground data. The solution of the embodiments of the present disclosure can improve the stability and reliability of the communication between the satellite and the ground station, ensure the smooth progress of the satellite control process, and thus promote the further development and application of space communication technology.

[0026] Regarding the defects of the above solutions and the proposed solutions, they are all the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure for the above problems in the following text should all be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0027] The following will describe this exemplary implementation manner in detail with reference to the accompanying drawings and embodiments.

[0028] Figure 1 The flowchart of a communication method in an embodiment of the present disclosure is shown. This communication method can be applied to the communication between a satellite and a ground station. That is to say, the sender can be the satellite and the receiver can be the ground station; or the sender can be the ground station and the receiver can be the satellite. As Figure 1 shown, the communication method provided in the embodiment of the present disclosure includes S101 - S103.

[0029] In S101, the sender sends a data frame to the receiver.

[0030] In S102, the receiver sends an acknowledgment signal (ACK) to the sender.

[0031] The inventors found in the research that the communication bandwidth of the satellite - ground transmission link is small, and considering the inter - satellite distance and on - satellite processing time, the round - trip time (RTT) of signal transmission is long. If waiting for the acknowledgment signal (ACK) of the previous data frame before sending the next data frame, valuable satellite - ground transmission resources will be wasted, resulting in low utilization efficiency. Therefore, in some embodiments, a multi - frame sending mechanism can be used at the beginning to improve the satellite - ground transmission efficiency, allowing the sender to send subsequent frame data without receiving the acknowledgment signal of the current frame. That is to say, in the above S101, the sender can send multiple data frames, for example, send n data frames, where n is a positive integer greater than or equal to 1. Correspondingly, S102 can be that the receiver sends n acknowledgment signals to the sender.

[0032] The embodiment of the present disclosure provides a lightweight protocol for the communication between a satellite and a ground station, mainly including a sender data - frame protocol and a receiver acknowledgment - signal protocol, which can reduce the overhead and complexity of the protocol and improve the communication efficiency by optimizing the data structure and transmission process of the protocol.

[0033] As Figure 2 shown, the data frame includes a frame header, the number of frames, the frame sequence, the frame length, and a data field.

[0034] Frame header: Identifies the service type and is used to distinguish the satellite - ground transmission service category.

[0035] Number of frames: The total number of frames for transmitting data. As an example, if the data to be transmitted is divided into 10 frames for transmission to the receiver, the total number of frames is 10.

[0036] Frame sequence: The sequence number of the current transmission frame.

[0037] Frame length: Represents the data length. In a single transmission task, except for the last frame, the frame length is a fixed value.

[0038] Data field: Fills the encoded data to be transmitted.

[0039] As shown Figure 2 in the figure, the response signal includes a frame header and a successful frame sequence.

[0040] Frame header: The service type is used to distinguish the satellite-ground transmission service category.

[0041] Successful frame sequence: Responds to the received data and is the frame sequence of the successfully received frames. If a reception error occurs during the transmission, the successful frame sequence maintains the previous frame sequence until the failed frame is retransmitted, and then the frame sequence is updated according to success or failure.

[0042] In some embodiments, in the above S101, the sender sends n data frames, and S102 may send one or more response signals according to the reception situation of the data frames. That is to say, if the receiver does not receive the data frame, it cannot send a response signal.

[0043] In some embodiments, in the above S101, the sender sends n data frames, and S102 the receiver sends n response signals to the sender.

[0044] Each of the n data frames includes a frame header, the number of frames, the frame sequence, the frame length, and a data field. The frame header records the service type, the number of frames records the total number of frames Q of the data transmitted in this communication, the frame sequence records the serial number of the current frame, the frame length records the data length of the current frame, and the data field is used to fill the data to be transmitted; among them, the frame sequences of the n data frames are 1 to n in sequence.

[0045] Each response signal includes a frame header and a successful frame sequence. The frame header records the service type, and the successful frame sequence is the frame sequence of the successfully received data frames.

[0046] In some embodiments, the maximum number n of data frames sent to the receiver each time is determined according to the round-trip time of a satellite and a ground station transmission and the transmission delay.

[0047] In the embodiments of the present disclosure, at the beginning, a multi-frame transmission mechanism is used to improve the satellite-ground transmission efficiency, allowing the sender to send subsequent frame data when the response signal of the current frame has not been received. Set the number of frames that can be sent in advance to n, and the calculation method of n can be: (1) In formula (1), RTT is the round-trip time of a satellite-ground transmission, and is the transmission delay. RTT is the sum of the transmission delay, the propagation delay, and the processing delay.

[0048] Transmission delay = packet length / sender bandwidth; Propagation delay = 2 link length / signal propagation speed; The processing delay is the processing time of the receiver for the transmitted data and can be obtained through tests on the satellite ground.

[0049] In S103, the sender determines how to send data frames to the receiver according to the successful frame sequence in the acknowledgment signal.

[0050] In some embodiments, in S101 above, the sender sends n data frames. If the sender in S103 determines that the successful frame sequence of one or more acknowledgment signals (ACK) received is from 1 to x, it continues to send data frames with frame sequences from n + 1 to n + x to the receiver, where 1 ≤ x ≤ n and n + x ≤ Q. That is to say, in the embodiments of the present disclosure, after receiving the acknowledgment signal (ACK) with a successful frame sequence of 1, a data frame with a frame sequence of n + 1 can be sent; after receiving the acknowledgment signal (ACK) with a successful frame sequence of 2, a data frame with a frame sequence of n + 2 can be sent; after receiving the acknowledgment signal (ACK) with a successful frame sequence of 3, a data frame with a frame sequence of n + 3 can be sent. That is, in the case of receiving acknowledgment signals (ACK) with successful frame sequences from 1 to 3, data frames with frame sequences from n + 1 to n + 3 can be sent. The embodiments of the present disclosure allow the sender to continue sending subsequent data frames when the acknowledgment signal (ACK) of the current frame has not been received, that is, it allows n data frames to be in the state of not receiving the acknowledgment signal (ACK), which can more efficiently utilize the communication link bandwidth, avoid the delay caused by sending only a single data frame each time and waiting for confirmation, and thus improve the overall data transmission efficiency.

[0051] As an example, in the scenario where in S101 above, the sender sends n data frames and in S102 the receiver sends n acknowledgment signals (ACK) to the sender, if the sender in S103 determines that the successful frame sequence of the n acknowledgment signals (ACK) is from 1 to n, it continues to send data frames with frame sequences from n + 1 to 2n to the receiver, where 2n ≤ Q. That is to say, when the sender determines that all the data frames already sent have been successfully received by the receiver, it continues to send new data frames to the receiver, thereby improving the reliability of data transmission between the satellite and the ground station.

[0052] In some embodiments, if n + x > Q, then continue to send data frames with frame sequences from n + 1 to Q to the receiver to complete the transmission of the communication data this time.

[0053] In one embodiment, it is set that the sender is the ground station and the receiver is the satellite, and 10 frames of data are transmitted from the ground to the satellite. It is set that the maximum number of data frames sent each time, n, is 3. Then the normal transmission process is as follows Figure 3As shown in the figure. The sender sequentially sends data frames with frame sequence numbers 1 - 3. After the receiver receives the data frame with frame sequence number 1, it sends an acknowledgment signal (ACK) with a successful frame sequence number of 1. Then, after the sender receives the acknowledgment signal (ACK) with a successful frame sequence number of 1, it sends a data frame with frame sequence number 4. After the receiver receives the data frame with frame sequence number 2, it sends an acknowledgment signal (ACK) with a successful frame sequence number of 2. Then, after the sender receives the acknowledgment signal (ACK) with a successful frame sequence number of 2, it sends a data frame with frame sequence number 5. Similarly, until the receiver receives the data frame with frame sequence number 7 and sends an acknowledgment signal (ACK) with a successful frame sequence number of 7. Then, after the sender receives the acknowledgment signal (ACK) with a successful frame sequence number of 7, it sends a data frame with frame sequence number 10. Subsequently, the sender ends this communication transmission after receiving the acknowledgment signals (ACK) with successful frame sequence numbers 8 - 10.

[0054] Data transmission errors may occur in the space - to - ground link. Embodiments of the present disclosure also provide an error re - transmission mechanism. In some embodiments, the successful frame sequence number is the frame sequence number of the data frame that is successfully received and has a correct reception status; when the data of the current frame is not correctly received by the receiver, the successful frame sequence number of the acknowledgment signal (ACK) corresponding to the current frame is set to the frame sequence number of the previous data frame with a correct reception status; the above method further includes: after receiving one or more acknowledgment signals (ACK) with successful frame sequence numbers from 1 to x, if the acknowledgment signal (ACK) with a successful frame sequence number of x is received again, then send data frames with frame sequence numbers from x + 1 to x + n to the receiver; where 1 ≤ x ≤ n, and n + x ≤ Q.

[0055] In one embodiment, as Figure 4 shown, the sender sequentially sends data frames with frame sequence numbers 1 - 3. After the receiver receives the data frames with frame sequence numbers 1 - 3, it sends acknowledgment signals (ACK) with successful frame sequence numbers 1 - 3. Then the sender sends data frames with frame sequence numbers 4 - 6. Assuming that the data frame with frame sequence number 4 is successfully transmitted and the data frame with frame sequence number 5 has a transmission error, then the successful frame sequence number of the acknowledgment signal (ACK) corresponding to the data frame with frame sequence number 4 is 4, and the successful frame sequence numbers of the acknowledgment signals (ACK) corresponding to the data frames with frame sequence numbers 5 and 6 are also 4. Correspondingly, when the sender receives 3 acknowledgment signals (ACK) with a successful frame sequence number of 4, it sends data frames with frame sequence numbers 5 - 7 to the receiver. Subsequently, if there are no other data frame transmission errors, the remaining transmission process is similar to that in the previous Figure 3 embodiment. Figure 4 In the embodiment, it is assumed that the fifth - frame data has a transmission error. Then, even if the subsequent frames are successfully transmitted, the successful frame sequence number of the receiver remains at 4. After the sender receives a repeated acknowledgment signal (ACK), it starts re - transmitting the data after the ACK successful frame sequence number.

[0056] In the embodiments of the present disclosure, for incorrect frames, the receiver's ACK successful frame sequence maintains the previous frame sequence. When the sender receives a repeated ACK successful frame sequence, it retransmits all the data after that frame sequence. Once the retransmission is successful, the receiver updates the successful frame sequence in the ACK frame. If the retransmission fails, the receiver's ACK successful frame sequence continues to maintain the previous frame sequence. The sender counts the number of retransmissions. Once the set number of retransmissions is exceeded, the current task transmission is terminated and marked as a failed transmission task.

[0057] The embodiments of the present disclosure also provide a timeout retransmission mechanism. In some embodiments, the method further includes: after receiving one or more acknowledgment signals (ACKs) with a successful frame sequence from 1 to x, if no acknowledgment signal (ACK) with a successful frame sequence of x + 1 is received within a preset duration after sending the data frame with a frame sequence of x + 1, then send data frames with frame sequences from x + 1 to x + n to the receiver; where 1 ≤ x ≤ n and n + x ≤ Q.

[0058] In some embodiments, if no acknowledgment signal (ACK) is received within the preset duration, continue to retransmit the data frames with frame sequences from x + 1 to x + n until the number of retransmissions is greater than the set number of retransmissions, and then terminate the transmission of the current communication data.

[0059] The above preset duration can also be referred to as the timeout duration. As Figure 5 shown, the sender sequentially sends data frames with frame sequences from 1 to 3. After the receiver receives the data frames with frame sequences from 1 to 3, it sends acknowledgment signals (ACKs) with successful frame sequences from 1 to 3. After the sender receives the acknowledgment signal (ACK) with a successful frame sequence of 1, it sends a data frame with a frame sequence of 4. After the receiver receives the data frame with a frame sequence of 2, it sends an acknowledgment signal (ACK) with a successful frame sequence of 2, and then after the sender receives the acknowledgment signal (ACK) with a successful frame sequence of 2, it sends a data frame with a frame sequence of 5. Similarly, after the receiver receives the data frames with frame sequences from 3 to 5, it sends acknowledgment signals (ACKs) with successful frame sequences from 3 to 5. However, due to certain reasons (such as the network environment), the sender does not receive acknowledgment signals (ACKs) with successful frame sequences from 3 to 5 within the timeout duration (preset duration). Then, the sender will retransmit the data frames with frame sequences from 3 to 5. If the sender subsequently receives acknowledgment signals (ACKs) with successful frame sequences from 3 to 5, the transmission is completed normally according to the previous embodiments. If the sender still does not receive any acknowledgment signals (ACK) within the preset duration, continue to retransmit until the number of retransmissions is greater than the set number of retransmissions, and then terminate the transmission of the current communication data. Figure 5 In the embodiment, it is assumed that the ACK frame of the third frame and subsequent ACK frames are lost, and the sender does not receive any reply ACK information within the timeout duration. After the timeout duration, the sender starts to retransmit the third frame and subsequent data.

[0060] In the embodiments of the present disclosure, when the sender does not receive any ACK information within the set timeout duration, it searches for the maximum value m of consecutive frame sequences starting from 1 in the received ACK information, and retransmits all data after the frame sequence of m + 1. If no ACK is received within the set timeout duration, it continues to retransmit until the number of retransmissions is greater than the set number of retransmissions, then terminates this task transmission and marks it as a transmission task failure. If an ACK is received within the set timeout duration, it starts message sending or retransmission according to the ACK message until the transmission task ends. The set timeout duration needs to be greater than the RTT.

[0061] In some embodiments, before the sender sends n data frames to the receiver, the method further includes: dividing the data to be transmitted in this communication into Q parts of data; for each part of the Q parts of data, encoding based on forward error correction to obtain Q parts of encoded data; constructing a data frame for each part of the encoded data, wherein the data field of each data frame is used to fill a part of the encoded data. Correspondingly, when receiving the data frame, the receiver uses a decoding method corresponding to the encoding method of the sender to decode, check, and correct the data in the received data frame; for error-free data, set the status to received correctly; for data with successful error correction, set the status to received correctly; for data that cannot be corrected through error correction, set the status to data reception error; wherein, the successful frame sequence is the frame sequence of the data frame that is successfully received and has the status of received correctly.

[0062] The embodiments of the present disclosure also provide a data verification and error correction mechanism. Before the sender sends data, it encodes the data based on forward error correction (such as convolutional codes, Turbo codes, and LDPC codes, etc.). After the receiver receives the data packet, it uses the decoding method corresponding to the encoding end to decode, check, and correct the received data. For error-free data, set the status to received correctly; for data that can be error-corrected, correct the data and set the status to received correctly; for data that cannot be corrected through error correction, set the status to data reception error.

[0063] In some embodiments, before the sender sends data, it can also calculate a check code (such as a CRC check code) for the data and attach the check code to the tail of the data packet for transmission together. After the receiver receives the data packet, it first calculates the same check code for the data part, and then compares the calculation result with the received check code. If they are consistent, it is considered that the data is received completely and correctly; if they are inconsistent, it is considered that there is an error in data reception.

[0064] In view of the special environment and requirements of space-ground TT&C communication, the embodiments of the present disclosure provide a reliability transmission method and protocol to ensure the reliable transmission of data between satellites and ground stations, effectively solving the problem that the data integrity cannot be guaranteed in existing space-ground TT&C communication; the embodiments of the present disclosure overcome the problem that the traffic control mechanism of general ground protocols such as TCP is too complex and time-consuming, and adopt a simplified traffic control strategy in satellite communication to reduce the computational overhead and latency; the embodiments of the present disclosure adaptively design an error retransmission and timeout retransmission mechanism for the characteristics of high latency of satellite links and low reliability of wireless links; the embodiments of the present disclosure design a streamlined transmission protocol for the limited bandwidth of space-ground transmission.

[0065] Figure 6 FIG. shows a flowchart of a communication method in an embodiment of the present disclosure. This communication method is executed by a sender, and the sender is a satellite or a ground station. That is to say, it can be that the sender is a satellite and the receiver is a ground station; or the sender is a ground station and the receiver is a satellite. As Figure 6 shown, the communication method provided in the embodiment of the present disclosure includes S601-S603.

[0066] In S601, n data frames are sent to the receiver. The data frame includes a frame header, the number of frames, the frame sequence, the frame length, and a data field. The frame header records the service type, the number of frames records the total number of frames Q of the data transmitted in this communication, the frame sequence records the sequence number of the current frame, the frame length records the data length of the current frame, and the data field is used to fill the data to be transmitted; among them, the frame sequences of the n data frames are 1 to n in sequence; In S602, one or more acknowledgment signals (ACK) are received from the receiver. Each acknowledgment signal (ACK) is sent by the receiver after receiving each data frame. Each acknowledgment signal (ACK) includes a frame header and a successful frame sequence. The frame header records the service type, and the successful frame sequence is the frame sequence of the successfully received data frame; In S603, if it is determined that the successful frame sequences of the one or more acknowledgment signals (ACK) received are 1 to x, then data frames with frame sequences of n+1 to n+x are continued to be sent to the receiver, where 1≤x≤n and n+x≤Q.

[0067] In view of the special requirements of space-ground TT&C communication, the embodiments of the present disclosure provide a new reliability transmission method and protocol, which can guarantee the reliable transmission of space-ground data and avoid the implementation difficulty and resource overhead brought by using an overly complex reliability communication protocol at the same time.

[0068] Figure 7 FIG. shows a flowchart of a communication method in an embodiment of the present disclosure. This communication method is executed by a receiver, and the receiver is a satellite or a ground station. That is to say, it can be that the sender is a satellite and the receiver is a ground station; or the sender is a ground station and the receiver is a satellite. As Figure 7As shown, the communication method provided in the embodiments of the present disclosure includes S701 - S702.

[0069] In S701, receive n data frames from a sender. The data frame includes a frame header, the number of frames, the frame sequence, the frame length, and a data field.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0073] In addition, although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that these steps must be executed in that specific order, or that all the steps shown must be executed to achieve the desired result.

[0074] In some embodiments, certain steps can be omitted, multiple steps can be combined into one step for execution, and / or one step can be decomposed into multiple steps for execution, etc.

The frame header records the service type, and the successful frame sequence is the frame sequence of the data frame that has been successfully received. The second sending module 803 is configured to determine that the successful frame sequences of the received one or more response signals are from 1 to x, and then continue to send data frames with frame sequences from n + 1 to n + x to the receiving party, where 1 ≤ x ≤ n and n + x ≤ Q.

[0077] In some embodiments, the second sending module 803 is further configured to, if n + x > Q, continue to send data frames with frame sequences from n + 1 to Q to the receiving party to complete the transmission of the communication data this time.

[0078] In some embodiments, the successful frame sequence is the frame sequence of the data frame that has been successfully received and has a correct reception status. When the receiving party fails to correctly receive the data of the current frame, the successful frame sequence of the response signal corresponding to the current frame is set to the frame sequence of the previous data frame with a correct reception status. The second sending module 803 is further configured to, after receiving one or more response signals with successful frame sequences from 1 to x, if a response signal with a successful frame sequence of x is received again, send data frames with frame sequences from x + 1 to x + n to the receiving party; where 1 ≤ x ≤ n and n + x ≤ Q.

[0079] In some embodiments, the second sending module 803 is further configured to, after receiving one or more response signals with successful frame sequences from 1 to x, if a response signal with a successful frame sequence of x + 1 is not received within a preset time period after sending the data frame with frame sequence x + 1, send data frames with frame sequences from x + 1 to x + n to the receiving party; where 1 ≤ x ≤ n and n + x ≤ Q.

[0080] In some embodiments, the second sending module 803 is further configured to, if no response signal is received within the preset time period, continue to retransmit the data frames with frame sequences from x + 1 to x + n until the number of retransmissions is greater than the set number of retransmissions, and then terminate the transmission of the communication data this time.

[0081] In some embodiments, the maximum number n of data frames sent to the receiving party each time is determined according to the round-trip time of one transmission between the satellite and the ground station and the transmission delay.

[0082] In some embodiments, the communication device further includes an encoding module and a data frame construction module.

[0083] The encoding module is configured to divide the data to be transmitted in this communication into Q pieces of data; for each piece of data among the Q pieces of data, perform encoding based on forward error correction to obtain Q pieces of encoded data; The data frame construction module is configured to construct a data frame for each piece of encoded data, wherein the data field of each data frame is used to fill a piece of encoded data.

The communication device is disposed in a satellite or a ground station and serves as a receiving party of communication. As Figure 9 shown, the communication device includes a second receiving module 901 and a third transmitting module 902.

[0085] The second receiving module 901 is configured to receive n data frames from a transmitting party. The data frame includes a frame header, the number of frames, a frame sequence number, a frame length, and a data field. The frame header records the service type, the number of frames records the total number of frames Q of the data transmitted in this communication, the frame sequence number records the sequence number of the current frame, the frame length records the data length of the current frame, and the data field is used to fill the data to be transmitted; wherein, the frame sequence numbers of the n data frames are sequentially from 1 to n; The third transmitting module 902 is configured to send one or more acknowledgment signals to the transmitting party. Each acknowledgment signal includes a frame header and a successful frame sequence number. The frame header records the service type, and the successful frame sequence number is the frame sequence number of the data frame successfully received, so that the transmitting party continues to send data frames with frame sequence numbers from n + 1 to n + x to the receiving party when it is determined that the successful frame sequence numbers of the one or more acknowledgment signals received are from 1 to x, where 1 ≤ x ≤ n and n + x ≤ Q.

[0086] In some embodiments, the communication device further includes a decoding module and a status setting module.

[0087] The decoding module is configured to use a decoding method corresponding to the encoding method of the transmitting party to decode, verify, and correct the data in the received data frame; The status setting module is configured to set the status to received correctly for error-free data; set the status to received correctly for data with successful error correction; set the status to data reception error for data that cannot be corrected through error correction; wherein, the successful frame sequence number is the frame sequence number of the data frame successfully received and with the status of received correctly.
