System, method and transmission device for transmitting data via multi-channel communications

1. Technical Field

The present disclosure relates to a system, a method and a transmission device for transmitting data via multi-channel communications.

2. Description of Related Art

Although communication devices have a number of data transmission modes, such as Bluetooth transmit mode, a WiFi transmission mode and so on, only one mode can be employed each time to transmit a piece of data such as a song. Therefore, there is a need to transmit a piece of data via a number of data transmission modes, thus to reduce time and improve the efficiency of transmission.

Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.

FIG. 1 is a block diagram of a system for transmitting data via multi-channel communications.

FIG. 2 is a flowchart of a method for transmitting data via multi-channel communications.

FIG. 1 shows a block diagram of a system 10 for transmitting data via multi-channel communications. The system 10 includes a data transmission device 20 and a data receiving device 30 . The data transmission device 20 is configured to transmit a piece of data to the data receiving device 30 in response to a manual operation.

The data transmission device 20 includes a storage module 21 , a data split module 22 , a channel control module 23 , a data distribution module 24 and a number of transmission modules 26 . The number of transmission modules 26 can be modules under different transmission protocols. Such as, one is a Bluetooth transceiver and another is a WiFi transceiver. The data receiving device 30 includes a number of receiving modules 31 . The transmission modules 26 are respectively corresponding to the receiving modules 31 and configured to communicate with the receiving modules 31 to build a number of transmission channels. Therefore, correspondingly, the number of receiving modules 31 can be modules under different transmission protocols. Such as, one is a Bluetooth transceiver and another is a WiFi transceiver. The transmission channels are corresponding to a number of data transmission modes. For example, one of the transmission modules 26 communicates with one of the receiving modules 31 to build a Bluetooth transmission channel corresponding to a Bluetooth transmission mode. Another one of the transmission modules 26 communicates with another one of the receiving modules 31 to build a WiFi transmission channel corresponding to a WiFi transmission mode.

The storage module 21 is configured to store data. The channel control module 23 is configured to provide manually selectable transmission modes and determine transmission channels and transmission modules 26 corresponding to selected transmission modes. The data split module 22 is configured to split a piece of data to be transmitted to a number of data segments. The number of the data segments is equal to the number of the determined transmission channels. The data segments are to be transmitted via the determined transmission channels. A size of each data segment is determined by a size of the piece of data and transmission speeds corresponding to the determined transmission channels, in order that transmissions in the determined transmission channels can be completed generally at the same time.

For example, the size of the piece of data is M. The determined transmission channels include three channels and the transmission speeds corresponding to the three channels are respectively a1 bit/s, a2 bit/s and a3 bit/s. Correspondingly, the data split module 22 splits the data to three data segments and the size of the three data segments are respectively M×a1/(a1+a2+a3), M×a2/(a1+a2+a3) and M×a3/(a1+a2+a3). Thus, the time to complete the transmission of each data segment via the corresponding determined transmission channel is M/(a1+a2+a3), and the time to complete the transmission of the whole piece of data is also M/(a1+a2+a3).

The data split module 22 is further configured to label a sequence number to each data segment. The data distribution module 24 is configured to distribute the labeled data segments to corresponding transmission modules 26 corresponding to the determined transmission channels to transmit the corresponding labeled data segments to the corresponding receiving module 31 via the corresponding determined transmission channels.

The receiving modules 31 corresponding to the determined transmission module 26 receive the corresponding labeled data segments. The data receiving device 30 further includes a data combination module 32 . The data combination module 32 is configured to identify the sequence number of each labeled data segment and combine the labeled data segments according to the sequence numbers to recover the data.

In another exemplary embodiment, the data transmission device 20 further includes a transmission determining module 25 . The transmission determining module 25 is configured to detect each transmission module 26 to determine whether the transmission module 26 completes the transmission of the corresponding data segment. The channel control module 23 is further configured to close the transmission module 26 to disconnect the transmission channel corresponding to the transmission module 26 when the transmission module 26 completes the transmission of the corresponding data segment.

FIG. 2 shows a flowchart of a method for transmitting data via multi-channel communications.

In step S 40 , the channel control module 23 provides transmission modes to be selected and determines transmission channels and transmission modules 26 corresponding to the selected transmission modes.

In step S 41 , the data split module 22 splits a piece of data to be transmitted to a number of data segments. The number of the data segments is the same as the number of the determined transmission channels. The size of each data segment is determined by the size of the data and transmission speeds corresponding to the determined transmission channels, in order that transmissions in the determined transmission channels can be completed generally at the same time.

For example, the size of the piece of data is M. The determined transmission channels include three channels and the transmission speeds corresponding to the three channels are respectively a1 bit/s, a2 bit/s and a3 bit/s. Correspondingly, the data split module 22 splits the data to three data segments and the size of the three data segments are respectively M×a1/(a1+a2+a3), M×a2/(a1+a2+a3) and M×a3/(a1+a2+a3). Thus, the time to complete the transmission of each data segment via the corresponding determined transmission channel is M/(a1+a2+a 3 ), and the time to complete the transmission of the whole piece of data is also M/(a1+a2+a3).

In step S 42 , the data split module 22 labels a sequence number to each data segment.

In step S 43 , the data distribution module 24 distributes the labeled data segments to the corresponding determined transmission modules 26 .

In step S 44 , the determined transmission modules 26 transmit the corresponding labeled data segments via the corresponding determined transmission channels.

In step S 45 , the transmission determining module 25 detects each transmission module 26 to determine whether the transmission module 26 completes the transmission of the corresponding data segment. If the transmission module 26 completes the transmission of the corresponding data segment, the process goes to S 46 . Otherwise the process goes to S 44 .

In step S 46 , the receiving modules corresponding to the determined transmission channels receives the corresponding labeled data segments.

In step S 47 , the data combination module 32 identifies the sequence number of each labeled data segment and combines the labeled data segments according to the sequence numbers to recover the data.

In step S 48 , the channel control module 23 closes the transmission module 26 to disconnect the transmission channel corresponding to the transmission module 26 .
