It should be noted that the following application scenarios are only shown to facilitate understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, the embodiments of the present application can be applied to any scenario where applicable.

The present application also provides a method, device, target terminal and medium for data transmission.

FIG. 1 schematically shows a schematic flowchart of a method for sending data according to an embodiment of the present application. As shown in Figure 1, the method includes:

S101. Determine, based on destination address information carried by a data stream to be sent, a receiving device and a set of transmission communication channels that can be used by the receiving device, where the set includes a first number of transmission communication channels.

It should be noted that this application does not limit the communication network using the data transmission method described in this application, that is, any communication network can be used. In one possible implementation, the communication network may be a High Performance Access Network over Coax (HINOC). HINOC is a technology that utilizes the coaxial cable channel to realize network communication. The protocol stack is shown in Figure 2, including the technical details of the physical layer (PHY layer) and the medium access control layer (MAC layer). The PHY layer defines the HINOC signal transmission mode, and the MAC layer implements the media access control and service adaptation functions in the HINOC system.

The communication network can use the method of channel bonding to improve the bandwidth, that is, on the basis of the original single-channel digital communication, the bandwidth is increased by the method of multi-channel bonding, and the communication rate is improved. However, there is currently no mechanism for sending data through multiple transmission communication channels applicable to the HINOC network system. The data sending method proposed in this application can solve the above problems.

Based on the destination address information of the data stream to be sent, such as the MAC address, the receiving device of the data stream can be determined, that is, the terminal to which the data stream to be sent is sent; according to the terminal, the transmission communication that can be used by the terminal can be determined channel collection. In the HINOC system using multi-channel bonding, the terminal equipment simultaneously transmits data on multiple transmission communication channels. The set of transmission communication channels includes all channels that can communicate between the central office and the terminal.

In addition, the data stream to be sent in this application may be various types of messages, for example, may include a broadband data stream, a video data stream, an audio data stream, or a management data stream, and the like.

It should also be noted that this application does not specifically limit the number of data streams to be sent, for example, it may be one or multiple.

It should also be noted that the data sending method in the present application is applicable to both the sending of the downstream data stream and the sending of the upstream data stream. In the embodiment of the present application, the sending of the downlink data stream is taken as an example, in this case, the central office device is the sender of the data stream to be sent, and the terminal device is the receiver of the data stream to be sent.

S102: Perform encapsulation processing on the data frames in the data stream to be sent, the encapsulation processing at least includes adding a frame sequence number to each of the data frames, wherein the frame sequence numbers are different from each other in the first time period, so The first time period is greater than or equal to the maximum transmission delay for sending the data stream.

In this application, the data stream to be sent will be sent through multiple transmission communication channels. Since the transmission rate of each transmission communication channel is different, the time of the split data stream to be sent to the peer terminal device will not be the same sooner or later. same. Therefore, in order to solve the problem of out-of-order when each sub-data stream arrives at the terminal device, the present application marks each data frame corresponding to the data stream to be sent with the corresponding frame sequence number, wherein the frame sequence numbers are different from each other within the time period of the maximum transmission delay. same. In this way, when the sub-data stream is transmitted to the terminal, the out-of-order data frame can be completely restored to the data stream to be sent according to the frame sequence number corresponding to each data frame.

S103. Select a second number of transmission communication channels from the set of transmission communication channels, where the second number is less than or equal to the first number.

The transmission communication channel in the transmission communication channel set is not completely suitable for the sending of the current data stream to be sent, there are many reasons, for example: the channel parameter of the transmission communication channel changes, resulting in a lower transmission rate of the channel; or, There are too many transmission tasks for other data streams on the transmission communication channel, resulting in a heavy traffic load on the channel; or, the quality of service (QoS) requirement of the data stream to be sent itself has specific requirements on the transmission channel.

In view of the above problems, the method described in this application will screen the set of transmission communication channels, and select a second number of transmission communication channels, wherein there may be multiple screening strategies.

Optionally, in a possible implementation manner of the present application, the transmission rate of each transmission communication channel may be acquired based on the channel parameters of each transmission communication channel in the set, and the transmission rate may be sorted from the set according to the order of the transmission rate. selects a second number of transmission communication channels; or,

Optionally, in another possible implementation manner of the present application, based on the service parameters of each transmission communication channel in the set, the service load of each transmission communication channel is acquired, and the service load is sorted from the set according to the order of the service load. A second number of transmission communication channels are selected.

S104: Divide the data stream to be sent into a second number of sub-data streams, and use the second number of transmission channels to send, wherein each transmission communication channel is used to send a corresponding sub-data stream.

The division ratio of the sub-data stream may adopt various strategies, for example, the data stream to be sent is divided into the second amount of sub-data. Optionally, in another possible implementation manner of the present application, the split ratio of the data stream to be sent may be determined based on the transmission rate or service load of the second number of transmission communication channels.

It should be noted that, in a possible embodiment of the present application, the transmission communication channel may be a physical layer PHY communication channel in a HINOC communication network. Each sub-data stream completes baseband modulation processing and radio frequency processing in its corresponding physical layer PHY communication channel. The baseband modulation processing includes the following items: interleaving, error correction coding, constellation mapping and OFDM modulation; the radio frequency processing The process includes at least one of the following: carrier modulation, power amplification.

Further, when the terminal device receives the second number of sub-data streams, it sorts the second number of sub-data streams based on the frame sequence number corresponding to each sub-data stream, and integrates them into a target data stream.

In this application, after the first number of transmission communication channels is determined, the data stream to be sent can be transmitted and sent through the plurality of transmission communication channels, so as to avoid the problem of only using a single communication channel to send information in the related art disadvantages.

Further optionally, in S103 (selecting a second number of transmission communication channels from the set of transmission communication channels), the present application includes the following steps:

Based on the channel parameters of each transmission communication channel in the set, obtain the transmission rate of each transmission communication channel, and select a second number of transmission communication channels from the set according to the order of the transmission rate; or, based on each transmission communication channel in the set The service parameters of the channel are used to obtain the service load of each transmission communication channel, and a second number of transmission communication channels are selected from the set according to the sorting of the service load.

Further optionally, in S103 (slicing the data stream to be sent into a second number of sub-data streams), the present application includes the following steps:

Based on the transmission rate or service load of the second number of transmission communication channels, the split ratio of the data stream to be sent is determined, and the split ratio is used to determine the size of each sub-data stream.

Further, after the data stream to be sent is divided into a second number of sub-data streams and sent using the second number of transmission channels, the present application further includes:

When the receiving device receives the second number of sub-data streams, it sorts the second number of sub-data streams based on the frame sequence numbers corresponding to each of the sub-data streams, and integrates them into a target data stream.

It should be noted that the transmission communication channel in this application may be a physical layer PHY communication channel in the HINOC communication network.

In this application, since the transmission rate of each transmission communication channel is different, the time of the split data stream to be sent to the opposite terminal device is also different sooner or later. Therefore, in order to avoid the disadvantage that each sub-data stream cannot be aggregated into the original video stream when it reaches the terminal device. In order to further ensure the accurate arrival of the data stream in the present application, each data frame corresponding to the data stream to be sent may be marked with a corresponding unique frame sequence number, wherein each unique frame sequence number is a frame sequence number that is different from each other. In this way, when the data stream is smashed and transmitted to the terminal, the smashed data stream can be completely restored to the data stream to be sent according to the unique frame sequence number corresponding to each data frame.

As shown in Figure 3, the target communication network is the HINOC communication network, the transmission communication channel is the PHY channel, and the number is M as an example to illustrate:

The present application can use the terminal receiving the data stream to configure the PHY channel of the terminal and allocate bandwidth when it is detected that there is currently a data stream to be sent, for example, terminal 1 works on the PHY1 and PHY2 channels, and terminal 2 works on the PHY3 channel; the data stream enters After the transmitter, judge whether the data stream enters the queue Q1 of terminal 1 or the queue Q2 of terminal 2 according to the MAC address; at the transmitter, PHY1 to PHY4 respectively give the communication channel parameters (PHY channel ID number, transmission rate between channels, etc.) , and M transmission communication channels (respectively PHY1, PHY2, PHY3, and PHYM) are determined based on the parameters of each communication channel. Then, take out the data frames required by PHY1 to PHYM from the MAC storage queue in turn, send them to each PHY channel, and use each of the data frames in this application to determine the receiving device and the receiving device based on the destination address information carried by the data stream to be sent. After the set of transmission communication channels that can be used, the data frames in the data stream to be sent can be encapsulated, and a second number of transmission communication channels can be selected from the set of transmission communication channels, where the second number is less than or equal to the first number, and then The data stream to be sent is divided into a second number of sub-data streams, and sent using the second number of transmission channels, wherein each transmission communication channel is used to send a corresponding sub-data stream. By applying the technical solutions of the present application, before sending the data stream to be sent in the communication network, it is possible to first determine a plurality of transmission communication channels in the communication system, and use the Multiple communication channels are used for transmission and transmission. In this way, the problem of unreliable message arrival caused by only using a single communication channel to send a data stream existing in the related art is avoided.

The transmission communication channel transmits the corresponding data frame. It should be noted that, at the data receiving end, the present application can obtain the original data stream to be sent after reordering the received multiple sub-data streams.
