It should be noted that the following application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.
The application also provides a data sending method, a data sending device, a target terminal and a medium.
Fig. 1 schematically shows a flow chart of a method for data transmission according to an embodiment of the present application. As shown in fig. 1, the method includes:
s101, determining a receiving device and a transmission communication channel set which can be used by the receiving device based on destination address information carried by a data stream to be sent, wherein the set comprises a first number of transmission communication channels.
The present application does not limit a communication network using the data transmission method described in the present application, and may be any communication network. In one possible implementation, the communication network may be a high performance coaxial access network (HINOC). HINOC is a technology for realizing network communication by using a coaxial cable channel, and a protocol stack is shown in figure 2 and comprises technical details of a physical layer (PHY layer) and a medium access control layer (MAC layer). The PHY layer defines a HINOC signal transmission mode, and the MAC layer realizes media access control and service adaptation functions in the HINOC system.
The communication network can realize the bandwidth increase by adopting a channel binding method, namely, on the basis of the original single-channel digital communication, the bandwidth is increased by adopting a multi-channel binding mode, and the communication speed is increased. However, at present, there is no mechanism for transmitting data through multiple transmission communication channels in the HINOC network system. The data transmission method provided by the application can solve the problems.
Based on the destination address information of the data stream to be transmitted, such as the MAC address, the receiving device of the data stream, that is, to which terminal the data stream to be transmitted is transmitted, may be determined; and determining a transmission communication channel set which can be used by the terminal according to the terminal. In the HINOC system adopting multi-channel binding, terminal equipment simultaneously transmits data on a plurality of transmission communication channels. The transmission communication channel set comprises all channels which can be communicated between the local side and the terminal.
In addition, the data stream to be transmitted in the present application may be various types of messages, and may include, for example, a broadband data stream, a video data stream, an audio data stream, a management data stream, or the like.
It should be noted that, the number of data streams to be transmitted is not specifically limited in this application, and may be, for example, one or multiple data streams.
It should be noted that the data transmission method in the present application is applicable to both downlink data stream transmission and uplink data stream transmission. In the embodiment of the present application, taking the sending of the downlink data stream as an example, at this time, the office device is a sender of the data stream to be sent, and the terminal device is a receiver of the data stream to be sent.
S102, encapsulating the data frames in the data stream to be sent, wherein the encapsulating at least comprises adding a frame sequence number to each data frame, the frame sequence numbers are different from each other in a first time period, and the first time period is greater than or equal to the maximum transmission delay of the data stream sending.
In the application, the data stream to be sent is sent through a plurality of transmission communication channels, and the transmission rate of each transmission communication channel is different, so that the time for sending the segmented data stream to the opposite terminal equipment is different. Therefore, in order to solve the problem of disorder when each sub-data stream reaches the terminal device, each data frame corresponding to the data stream to be sent is respectively marked with a corresponding frame number, wherein the frame numbers are different from each other within the time period of the maximum transmission delay. Therefore, when the sub-data stream is transmitted to the terminal, the disordered data frames can be completely restored into the data stream to be sent according to the frame sequence number corresponding to each data frame.
S103, selecting a second number of transmission communication channels from the transmission communication channel set, wherein 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 transmission of the current data stream to be transmitted, and the reasons include various reasons, for example: the channel parameters of the transmission communication channel are changed, so that the transmission rate of the channel is low; or, the transmission tasks of other data streams on the transmission communication channel are too many, resulting in a larger traffic load of the channel; or, the quality of service (QoS) requirement of the data flow to be transmitted has a specific requirement on the transmission channel.
In view of the above problems, the method according to the present application screens the set of transmission communication channels to select a second number of transmission communication channels, where the screening policy may be multiple.
Optionally, in a possible implementation manner of the present application, the transmission rate of each transmission communication channel may be obtained based on the channel parameter of each transmission communication channel in the set, and a second number of transmission communication channels may be selected from the set according to the ordering of the transmission rates; or,
optionally, in another possible implementation manner of the present application, a service load of each transmission communication channel is obtained based on a service parameter of each transmission communication channel in the set, and a second number of transmission communication channels are selected from the set according to a ranking of the service loads.
And S104, dividing the data stream to be transmitted into a second number of sub-data streams, and transmitting the sub-data streams by using the second number of transmission channels, wherein each transmission communication channel is used for transmitting a corresponding sub-data stream.
The splitting ratio of the sub-data stream may adopt various strategies, for example, all the data streams to be sent are split into the second number of sub-data. Optionally, in another possible implementation manner of the present application, the slicing ratio of the data stream to be transmitted may be determined based on a transmission rate or a traffic load of the second number of transmission communication channels.
It should be noted that, in one 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 a baseband modulation processing process and a radio frequency processing process in a corresponding physical layer (PHY) communication channel, wherein the baseband modulation processing comprises one of the following items: interleaving, error correction coding, constellation mapping and OFDM modulation; the radio frequency processing procedure comprises at least one of the following: carrier modulation and power amplification.
Further, when the terminal device receives the second number of sub-streams, the second number of sub-streams are sequenced based on the frame number corresponding to each sub-stream, and are integrated into a target data stream.
In the application, after the first number of transmission communication channels is determined, the data stream to be transmitted can be transmitted and transmitted through the plurality of transmission communication channels, so that the defect that information is transmitted only by using a single communication channel in the related art can be avoided.
Further optionally, in S103 (selecting a second number of transmission communication channels from the transmission communication channel set), the method includes the following steps:
acquiring the transmission rate of each transmission communication channel based on the channel parameters of each transmission communication channel in the set, and selecting a second number of transmission communication channels from the set according to the sequence of the transmission rates; or, based on the service parameter of each transmission communication channel in the set, the service load of each transmission communication channel is obtained, and a second number of transmission communication channels are selected from the set according to the ordering of the service loads.
Further optionally, in S103 (dividing the data stream to be transmitted into a second number of sub-data streams), the method includes the following steps:
and determining the segmentation proportion of the data stream to be transmitted based on the transmission rate or the service load of the second number of transmission communication channels, wherein the segmentation proportion is used for determining the size of each sub-data stream.
Further, after dividing the data stream to be transmitted into a second number of sub-data streams and transmitting the sub-data streams by using a second number of transmission channels, the method further includes:
and when the receiving equipment receives the sub-data streams of the second number, sequencing the sub-data streams of the second number based on the frame number corresponding to each sub-data stream, and integrating the sub-data streams of the second number into the target data stream.
It should be noted that, the transmission communication channel in the present application may be a physical layer PHY communication channel in a HINOC communication network.
In the application, the transmission rate of each transmission communication channel is different, so the time for the segmented data stream to be sent to the opposite terminal equipment is different. Therefore, the disadvantage that each sub-data stream cannot be aggregated into the original video stream when reaching the terminal device is avoided. In order to further ensure accurate arrival of the data stream, each data frame corresponding to the data stream to be sent may be respectively labeled with a corresponding unique frame number, where each unique frame number is a frame number different from each other. Therefore, when the data stream is transmitted to the terminal under the condition of scattering, the scattered data stream can be completely restored into the data stream to be sent according to the unique frame number corresponding to each data frame.
As shown in fig. 3, the target communication network is an HINOC communication network, the transmission communication channels are PHY channels, and the number of the transmission communication channels is M, for example:
when detecting that a data stream to be transmitted currently exists, the method can configure a PHY channel of a terminal and allocate bandwidth by using a terminal receiving the data stream, for example, a terminal 1 operates in PHY1 and PHY2 channels, and a terminal 2 operates in PHY3 channels; after the data stream enters the transmitter, judging whether the data stream enters a queue Q1 of a terminal 1 or a queue Q2 of a terminal 2 according to the MAC address; at the transmitting end, the PHYs 1 to 4 give communication channel parameters (PHY channel ID number, inter-channel transmission rate, etc.), respectively, and determine M transmission communication channels (PHY 1, PHY2, PHY3, PHYM, respectively) based on the respective communication channel parameters. And then sequentially taking out data frames required by PHYs 1 to PHYM from the MAC storage queue, sending the data frames to each PHY channel, and using the data frames in each PHY channel, after determining a receiving device and a transmission communication channel set usable by the receiving device based on destination address information carried by a data stream to be sent, encapsulating the data frames in the data stream to be sent, and selecting a second number of transmission communication channels from the transmission communication channel set, where the second number is less than or equal to the first number, then dividing the data stream to be sent into a second number of sub-data streams, and sending the sub-data streams using the second number of transmission channels, where each transmission communication channel is used to send one corresponding sub-data stream. By applying the technical scheme of the application, before the data stream to be sent in the communication network is sent, a plurality of transmission communication channels in the communication system are determined, and the data stream to be sent is transmitted and sent by using the plurality of communication channels after being respectively marked with the unique frame number. Thereby avoiding the problem of unreliable message arrival caused by using only a single communication channel to transmit data stream in the related art.
And the transmission communication channel transmits the corresponding data frame. It should be noted that, at the data receiving end, the present application may reorder the received multiple sub-data streams to obtain the original data stream to be sent.
In another embodiment of the present application, as shown in fig. 4, the present application further provides a communication mode selection device. Wherein the device comprises a sending module 301, a processing module 302, a selecting module 303, and a cutting module 304, wherein,
