[0016] Hereinafter, the embodiments of the present disclosure will be described in detail, examples of which are shown in the accompanying drawings, in which the same or similar reference numerals throughout indicate the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are only intended to illustrate the present disclosure, and are not to be understood as limitations on the present disclosure. Rather, the embodiments of the present disclosure include all changes, modifications, and equivalents contained within the spirit and scope of the appended claims.

[0017] In the related art, data transmission is affected by network jitter, which affects the efficiency of retransmission control of data packets, and therefore affects the stability of communication between devices and communication quality.

[0018] Therefore, the embodiments of the present disclosure provide a data transmission control method, a device, an electronic device, a computer-readable storage medium, experience The present invention provides a method and a computer program for effectively improving the retransmission control efficiency of data packets, thereby avoiding the effects of network jitter, and effectively improving the retransmission control effect of data packets, and effectively improving the communication stability and communication quality between devices.

[0019] The data transmission control method will be described below in conjunction with a specific embodiment.

[0020] FIG. 1 is a schematic flowchart of a data transmission control method proposed by an embodiment of the present disclosure.

[0021] In addition, the entity that executes the data transmission control method of this embodiment is a data transmission control device, which can be realized by software and / or hardware and may be disposed in an electronic device, which may include, but is not limited to, a terminal, a server, etc.

[0022] The data transmission control method of this embodiment can be applied to a first device, and the first device receives a data packet transmitted from a second device, i.e., the first device may be an electronic device that receives a data packet transmitted from the second device, and accordingly, the second device may be an electronic device that transmits a data packet to the first device, but is not limited thereto.

[0023] As shown in FIG. 1, this data transmission control method includes the following steps S101 to S103.

[0024] S101, receiving a first data packet transmitted from a second device, and determining first time information corresponding to the first data packet.

[0025] Here, the data packet may refer to blocked network data, for example, a second device may transmit a data packet for communication to a first device via a communication network, which may be a wide area network, a local area network, and is not limited thereto.

[0026] Here, the data packet currently being transmitted from the second device received by the first device can be referred to as the first data packet, and this first data packet has some associated time information, which can be referred to as the first time information, and the first time information is, for example, the time when the first device received this first data packet, or the time when the second device transmitted this first data packet, but is not limited thereto.

[0027] When receiving a first data packet transmitted from the second device, first time information corresponding to the first data packet can be determined in real time, and the first time information can be used to determine a degree of network jitter in the communication network.

[0028] In some embodiments, determining the first time information corresponding to the first data packet may include determining a first receiving time when the first data packet was received and analyzing a first timestamp corresponding to the first data packet, where the first timestamp is a timestamp when a second device transmitted the first data packet; using the first receiving time and the first timestamp as the first time information enables the time information related to the first data packet to be quickly determined; using the first receiving time and the first timestamp as the related time information and using the related time information for calculating a network jitter degree value can help to easily determine the network jitter degree value, improve the referenceability of the calculated network jitter degree value, and help effectively improve the retransmission control effect of the data packet.

[0029] That is, in this embodiment, when determining the first time information corresponding to the first data packet, the time when the first device received the first data packet, i.e., the reception time of the first data packet, is determined, and the time when the second device transmitted the first data packet (first timestamp) is determined, so that two pieces of time information related to the first data packet can be obtained, and the two pieces of time information related to the first data packet are time information corresponding to the first data packet.

[0030] Of course, any other possible time information related to the first data packet may be used as the first time information, for example, a corresponding mathematical operation may be performed on the first receiving time and the first timestamp, and the time value obtained by the operation may be used as the first time information, without being limited thereto.

[0031] S102, determining a network jitter degree value based on first time information and second time information, where the second time information is time information corresponding to a second data packet, and the second data packet is a data packet transmitted by the second device to the first device before transmitting the first data packet.

[0032] Here, the second data packet is a data packet transmitted by the second device to the first device before transmitting the first data packet, i.e., a data packet currently being transmitted from the second device received by the first device can be referred to as the first data packet, and correspondingly, a data packet transmitted from the second device received by the first device prior to the current time can be referred to as the second data packet.

[0033] This second data packet has some associated time information, which can be referred to as second time information, such as, but not limited to, the time when the first device received this second data packet or the timestamp when the second device transmitted this second data packet.

[0034] That is, in an embodiment of the present disclosure, a degree of network jitter can be determined correspondingly based on a first data packet currently being transmitted from a second device received by a first device and a second data packet transmitted from the second device received by the first device prior to the current time.

[0035] Here, network jitter refers to the fact that when congestion occurs in a network, queuing delay affects the end-to-end delay, and the delay of data packets transmitted through the same connection is different. Jitter represents the degree of such delay change, and the network jitter degree value can quantitatively represent the degree of this jitter, and the smaller the network jitter degree value, the more stable the quality of the communication network is, and conversely, the more unstable the quality of the communication network is.

[0036] In the embodiments of the present disclosure, the network jitter degree value is determined based on the first time information corresponding to the first data packet and the second time information corresponding to the second data packet in combination with certain algorithm logic, so that the network jitter degree value can be easily and accurately determined.

[0037] For example, when determining a network jitter degree value based on the first time information corresponding to the first data packet and the second time information corresponding to the second data packet, the network jitter degree value can be determined based on a pre-trained jitter detection model. For example, the first time information corresponding to the first data packet and the second time information corresponding to the second data packet can be input into the pre-trained jitter detection model to obtain a network jitter degree value output from the pre-trained jitter detection model. Or, the step of determining a network jitter degree value based on the first time information and the second time information can be performed in any other manner, and is not limited thereto.

[0038] In the embodiment of the present disclosure, the first receiving time and the first timestamp are the first time information as described above, and second time information corresponding to the second data packet can be further determined, and the second time information can include a second receiving time and a second timestamp. The second receiving time is the time when the first device receives the second data packet, and the second timestamp is the timestamp when the second device transmits the second data packet, and determining a network jitter degree value based on the first time information and the second time information can be determining a network jitter degree value based on the first receiving time, the first timestamp, the second receiving time, and the second timestamp, so that the network jitter degree at the current time can be more accurately quantified and calculated, and the reference value of the network jitter degree in the retransmission control of the data packet can be effectively improved.

[0039] That is, the embodiment of the present disclosure can support determining a network jitter degree at a current time by referring to a first receiving time, a first timestamp, a second receiving time, and a second timestamp, and during data communication, the correlation between the receiving times and timestamps of different data packets may have a certain relative relationship with the network jitter degree of the communication network, for example, the larger the network jitter degree, the greater the impact on the correlation between the receiving times and timestamps of different data packets; and the smaller the network jitter degree, the smaller the impact on the correlation between the receiving times and timestamps of different data packets.

[0040] Thus, in an embodiment of the present disclosure, it can be assisted to determine a network jitter degree value by referring to the first reception time, the first timestamp, the second reception time, and the second timestamp, for example, the first reception time, the first timestamp, the second reception time, and the second timestamp can be combined with a certain calculation process to obtain a network jitter degree value, but is not limited thereto.

[0041] S103, determine a retransmission timestamp based on the network jitter degree value, and send the retransmission timestamp to the second device.

[0042] After the network jitter degree value is determined based on the first time information and the second time information as described above, a retransmission timestamp can be determined based on the network jitter degree value, and the retransmission timestamp can be transmitted to the second device so that the second device can refer to the retransmission timestamp to perform data transmission control.

[0043] In this embodiment, a first data packet transmitted from the second device is received, first time information corresponding to the first data packet is determined, and a network jitter degree value is determined based on the first time information and the second time information, where the second time information is time information corresponding to the second data packet, and the second data packet is a data packet transmitted by the second device to the first device before transmitting the first data packet, and a retransmission timestamp is determined based on the network jitter degree value, and the retransmission timestamp is sent to the second device, thereby supporting retransmission control of the data packet in combination with the network jitter degree, so as to avoid the influence of network jitter, effectively improve the efficiency of retransmission control of the data packet, effectively improve the effect of retransmission control of the data packet, and effectively improve the stability and quality of communication between devices.

[0044] FIG. 2 is a schematic flowchart of a data transmission control method proposed according to another embodiment of the present disclosure.

[0045] The data transmission control method of this embodiment can be applied to a first device, and the first device receives a data packet transmitted from a second device, i.e., the first device may be an electronic device that receives a data packet transmitted from the second device, and accordingly, the second device may be an electronic device that transmits a data packet to the first device, but is not limited thereto.

[0046] As shown in FIG. 2, this data transmission control method includes the following steps S201 to S211.

[0047] S201, receiving a first data packet transmitted from a second device.

[0048] S202, determining a first receiving time when a first data packet is received.

[0049] S203, analyzing a first timestamp corresponding to the first data packet, the first timestamp being a timestamp when the second device transmits the first data packet, and the first receiving time and the first timestamp are taken as first time information.

[0050] The explanation of S201 to S203 can be specifically referred to in the above embodiment, and the explanation will be omitted here.

[0051] S204, determining a second receiving time at which the second data packet is received and a second timestamp corresponding to the second data packet, where the second receiving time is the time at which the first device receives the second data packet and the second timestamp is the timestamp at which the second device transmits the second data packet.

[0052] Here, a data packet transmitted from a second device received by a first device before the current time can be referred to as a second data packet, and this second data packet has some associated time information, and the associated time information of this second data packet can be referred to as second time information, and the second time information is, for example, but not limited to, the time when the first device received this second data packet (second receiving time), or the timestamp when the second device transmitted this second data packet (second timestamp).

[0053] In some embodiments, when the first device receives a second data packet transmitted from the second device, it can determine second time information corresponding to the second data packet in real time and record the second time information locally in the first device, so that when receiving a first data packet and analyzing a network jitter degree based on the first time information corresponding to the first data packet, it can directly read the stored second time information locally, and determine a network jitter degree in combination with the second time information based on the first time information.

[0054] S205, a first difference value between the first timestamp and the first receiving time is determined.

[0055] Here, the first timestamp refers to the timestamp when the second device transmits the first data packet.

[0056] That is, when a first device receives a first data packet transmitted from a second device, it can determine first time information corresponding to the first data packet, analyze the first time information to obtain a first timestamp and a first receiving time, and determine a difference value between the first timestamp and the first receiving time (the difference value can be referred to as a first difference value), and the first difference value can be used to determine a network jitter degree value.

[0057] For example, if the first timestamp at which the second device transmits the first data packet, i.e., the first timestamp, is t11, and the first receiving time at which the first device receives the first data packet transmitted from the second device is t12, then the difference value between t11 and t12 is the first difference value.

[0058] S206, a second difference value between the second timestamp and the second receiving time is determined.

[0059] Here, the second timestamp refers to the time when the second device transmits the second data packet.

[0060] That is, after the first device determines a first difference value between the first timestamp and the first receiving time, it can read the corresponding second timestamp and second receiving time from the local storage. Because the second data packet is transmitted by the second device to the first device before the current time, the second timestamp and the second receiving time can be pre-stored in the local storage of the first device to support direct reading.

[0061] The determined difference value between the second timestamp and the second receipt time may be referred to as a second difference value, which may be used in combination with the first difference value to determine a network jitter degree value.

[0062] For example, if the timestamp at which the second device transmits this second data packet, i.e., the second timestamp, is t21, and the second receiving time at which the first device receives the second data packet transmitted from the second device is t22, then the difference value between t21 and t22 is the second difference value.

[0063] S207: The difference between the second difference value and the first difference value is set as a network jitter degree value.

[0064] A first difference value between the first timestamp and the first receiving time is determined, and a second difference value between a second timestamp and the second receiving time is determined. Then, a difference value between the second difference value and the first difference value is determined, and this difference value can be used as a network jitter degree value.

[0065] That is, based on the second difference value and the first difference value, combined with corresponding mathematical operation logic, a network jitter degree value can be obtained.

[0066] Since the network jitter degree value is determined based on a first difference value between a first timestamp and the first receiving time, and a second difference value between a second timestamp and the second receiving time, the network jitter degree within the current time can be quickly and accurately determined, and the current time network jitter situation can be more accurately quantified, which can help effectively improve the retransmission control effect of data packets, and effectively help improve the communication stability and communication quality between devices.

[0067] S208, determining a target timestamp, where the target timestamp is a timestamp with a largest value among the plurality of timestamps, the plurality of timestamps respectively corresponding to the plurality of data packets received in the history period.

[0068] After the network jitter degree value is determined, the first device can determine the largest timestamp from a plurality of timestamps respectively corresponding to a plurality of data packets received within a history period as a target timestamp, and then combine the network jitter degree value and the target timestamp to determine a retransmission timestamp, which can be used to assist the second device in controlling retransmission of the data packet.

[0069] S209: determining a target reception time corresponding to the target timestamp, determining a time sum between the target timestamp and the target reception time, and determining a difference between the time sum and the network jitter degree value as the retransmission timestamp.

[0070] After the target timestamp is determined, a target reception time corresponding to the target timestamp is determined, a time sum between the target timestamp and the target reception time is determined, and a difference between the time sum and the network jitter degree value is determined as a retransmission timestamp.

[0071] For example, if within a history period, the target timestamp, i.e., the largest timestamp received, is 10000 ms, the target receipt time corresponding to the target timestamp is 50 ms, and the calculated network jitter degree value is 30 ms, then the total time value between the target timestamp and the target receipt time=10000 ms+50 ms=10050 ms, and the retransmission timestamp=10050 ms-30 ms=10020 ms.

[0072] Since the retransmission timestamp is calculated in combination with the target timestamp, the reception time corresponding to the target timestamp, and the network jitter degree value, the retransmission timestamp can be accurately obtained, thereby ensuring the accuracy of data packet retransmission control, and allowing the second device to control data packet transmission by referring to the retransmission timestamp.

[0073] S210, generating a packet loss retransmission NACK request message based on a retransmission timestamp.

[0074] After determining a retransmission timestamp based on the difference value between the target timestamp and the network jitter degree value, the first device can generate a packet loss retransmission NACK request message based on the retransmission timestamp, and trigger the second device to perform corresponding retransmission control on the data packet based on the packet loss retransmission NACK request message.

[0075] Here, the packet loss retransmission NACK request message refers to a case where a data sender sends a data packet to a receiver, and the receiver does not receive the corresponding data packet, and a data packet is lost during data transmission, the receiver generates a non-response message to request the sender to retransmit the corresponding lost data packet, and this non-response message can be called a packet loss retransmission NACK request message.

[0076] In this embodiment, the first device transmits a retransmission timestamp to a NACK Generator, which generates a packet loss retransmission NACK request message based on the retransmission timestamp, thereby triggering processing logic to subsequently send a packet loss retransmission NACK request message to the second device.

[0077] As shown in FIG. 3, FIG. 3 is a schematic configuration diagram of a packet loss retransmission NACK request message in an embodiment of the present disclosure.

[0078] S211, when a current time reaches a set time, sending a packet loss retransmission NACK request message to the second device.

[0079] After generating a packet loss retransmission NACK request message based on the retransmission timestamp, a timer is preset, timing control is performed based on the timer, and whether the current time has reached the time set on the timer is detected in real time. If the current time has reached the set time, a packet loss retransmission NACK request message can be sent to the second device.

[0080] In this embodiment, the NACK generator can control the transmission of the packet loss retransmission NACK request message by a timer. For example, when the first device receives a data packet, the timer can be triggered to start. The set time can be, for example, 100 ms, and can also be set to a subsequent Rtt (network time delay) time (minimum 30 ms), thereby supporting the periodic transmission of the packet loss retransmission NACK request message to the second device.

[0081] In this embodiment, a first data packet transmitted from a second device is received, a time when the first data packet is received is determined, a first timestamp corresponding to the first data packet is analyzed, the first timestamp is a timestamp when the second device transmits the first data packet, the first reception time and the first timestamp are first time information, a second reception time when the second data packet is received and a second timestamp corresponding to the second data packet are determined, the second reception time is a time when the first device receives the second data packet, and the second timestamp is a timestamp when the second device transmits the second data packet, and then a first difference value between the first timestamp and the first reception time is calculated. determine a first timestamp and a second difference value between the first timestamp and the second timestamp; obtain a network jitter degree value based on the second difference value and the first difference value; determine a target timestamp, the target timestamp being the largest timestamp among a plurality of timestamps, the plurality of timestamps corresponding to a plurality of data packets received in a history period respectively; determine a difference value between the target timestamp and the network jitter degree value as a retransmission timestamp; generate a packet loss retransmission NACK request message based on the retransmission timestamp; and send the packet loss retransmission NACK request message to the second device when the current time reaches a set time. By determining the network jitter degree value based on the first difference value between the first timestamp and the first receiving time and the second difference value between the second timestamp and the second receiving time, the network jitter degree within the current time can be quickly and accurately determined, and the current time network jitter situation can be more accurately quantified, which can support effective improvement of the retransmission control effect of data packets, and effectively support improvement of communication stability and communication quality between devices.In addition, the network jitter degree value and the target timestamp are combined to obtain a retransmission timestamp, and the first device generates a NACK request message based on the retransmission timestamp, thereby helping to accurately perform retransmission control for data packets and improving the effect of data transmission control.

[0082] FIG. 4 is a schematic flowchart of a data transmission control method proposed by another embodiment of the present disclosure.

[0083] The data transmission control method of this embodiment can be applied to a second device, and the second device transmits a data packet to the first device. That is, the first device may be an electronic device that receives the data packet transmitted from the second device. Accordingly, the second device may be an electronic device that transmits the data packet to the first device, but is not limited thereto.

[0084] As shown in FIG. 4, this data transmission control method includes the following steps S401 to S402.

[0085] S401, after a first data packet is transmitted to a first device, receiving a retransmission timestamp sent from the first device, where the retransmission timestamp is determined by the first device based on a network jitter degree value.

[0086] In this embodiment, after the first data packet is transmitted to the first device, the second device can monitor in real time whether a retransmission timestamp fed back from the first device is received, and if it detects that the retransmission timestamp has been received, it can trigger subsequent steps.

[0087] S402, data transmission control is performed based on the retransmission timestamp.

[0088] That is, after receiving the retransmission timestamp transmitted from the first device, the second device can refer to this retransmission timestamp and control the retransmission of the data packet.

[0089] In this embodiment, after a first data packet is transmitted to a first device, a retransmission timestamp sent from the first device is received, and data transmission control is performed based on the retransmission timestamp. Since the retransmission timestamp is determined by the first device based on a network jitter degree value, the influence of network jitter can be avoided and the accuracy of data packet retransmission control can be ensured.

[0090] FIG. 5 is a schematic flowchart of a data transmission control method proposed by another embodiment of the present disclosure.

[0091] The data transmission control method of this embodiment can be applied to a second device, and the second device transmits a data packet to the first device. That is, the first device may be an electronic device that receives the data packet transmitted from the second device. Accordingly, the second device may be an electronic device that transmits the data packet to the first device, but is not limited thereto.

[0092] As shown in FIG. 5, this data transmission control method includes the following steps S501 to S505.

[0093] S501, after a first data packet is transmitted to a first device, receive a packet loss retransmission NACK request message sent from the first device.

[0094] In this embodiment, the second device receives a packet loss retransmission NACK request message sent from the first device after the first data packet is transmitted to the first device.

[0095] S502, parsing the packet loss retransmission NACK request message to obtain a retransmission timestamp, where the retransmission timestamp is determined by the first device based on a network jitter degree value.

[0096] After transmitting a first data packet to the first device and receiving a packet loss retransmission NACK request message sent from the first device, the packet loss retransmission NACK request message can be analyzed to obtain a retransmission timestamp, and the retransmission timestamp is determined by the first device based on a network jitter degree value.

[0097] In this embodiment, when the second device receives a packet loss retransmission NACK request message sent from the first device, it can determine that a packet loss occurs during data transmission, and in this case, it can analyze the packet loss retransmission NACK request message generated by the first device to obtain the retransmission timestamp included in the NACK request message.

[0098] S503, analyzing the packet loss retransmission NACK request message to obtain at least one lost data packet identifier.

[0099] After parsing the packet loss retransmission NACK request message to obtain a retransmission timestamp, the packet loss retransmission NACK request message can be parsed to obtain at least one lost data packet identifier, and the data packet identifier can uniquely identify the corresponding data packet.

[0100] In this embodiment, when the second device receives a NACK request message sent from the first device, it can determine that a packet loss occurs during data transmission, in which case it can analyze the packet loss retransmission NACK request message generated by the first device to obtain one or more data packet identifiers lost during data transmission, and the one or more data packet identifiers can assist in determining corresponding data packets, without being limited thereto.

[0101] S504, determining at least one corresponding target data packet based on the at least one data packet identifier, where a timestamp corresponding to the target data packet is before the retransmission timestamp.
