When the data to be transmitted is multiple files, and the multiple files include a single file size greater than a preset threshold, the multiple files are segmented according to each file, and a single file whose size exceeds a preset threshold is also divided. For multiple sub-data segments.

S202: The transmitting terminal sets a short-distance transmission mode and a transmission sequence corresponding to each sub-data segment according to the size and sequence identifier of each sub-data segment;

It should be noted that, because the transmission rates of the short-distance transmission modes are inconsistent, the embodiments of the present invention can transmit more data according to a short-distance transmission method with a large transmission rate, and a short-distance transmission mode with a small transmission rate. The principle of transmitting a small amount of data is set.

The sending terminal sets the short-distance transmission mode and the transmission sequence corresponding to each sub-data segment according to the size and sequence identifier of each sub-data segment, including:

The transmitting terminal arranges all the sub-data segments according to the size and according to the short-distance transmission mode. The number of levels is divided; wherein the sub-data segment size within each level corresponds to a short-distance transmission mode;

The embodiment of the present invention provides a method for transmitting data in a short distance. By dividing the data to be transmitted and simultaneously transmitting the divided sub-data segments through multiple short-distance transmission methods, the rate at which the terminal transmits data in close proximity can be improved.

Based on the same technical concept of the foregoing embodiment, referring to FIG. 3, it shows another method for transmitting data in close distance according to an embodiment of the present invention. The method may be used for receiving terminals for transmitting data in close range, and the method includes :

S301: The receiving terminal receives at least one sub-data segment and a corresponding sequence identifier sent by the sending terminal according to the short-distance transmission mode and the transmission sequence corresponding to each sub-data segment;

The at least one sub-data segment and the corresponding sequence identifier are obtained by the transmitting terminal dividing the complete data to be transmitted according to a preset dividing rule; the sequence identifier corresponding to each sub-data segment is used to represent the sub-data. The order of the segments in the data to be transmitted. Specific division process The foregoing embodiment has been specifically described, and details are not described herein again.

The short-distance transmission mode and the transmission sequence of each sub-data segment are also set by the transmitting terminal. The specific configuration process is also specifically described in the foregoing embodiment, and details are not described herein again. After the sending terminal performs the short-distance transmission mode corresponding to each sub-data segment and the corresponding sequence identifier setting number, the receiving terminal can only receive the sub-data segment corresponding to the mode according to the corresponding short-distance transmission method. For example, the transmitting terminal transmits the sub-data segment 1 to the receiving terminal through the WIFI. It can be understood that the receiving terminal can only receive the sub-data segment 1 by means of WIFI transmission.

S302: The receiving terminal splices the at least one sub data segment into complete data to be transmitted according to the at least one sub data segment and the corresponding sequence identifier.

Illustratively, after receiving the sub-data segment and the corresponding sequence identifier sent by the receiving terminal, the receiving terminal may splicing the sub-data segments according to the sequence identifier, thereby obtaining complete data to be transmitted; and, the receiving terminal may further according to the sequence. The identification determines that the transmission of the sub-data segment is missing, so that when it is determined that the transmission of the sub-data segment is missing, the transmitting terminal is requested to retransmit the missing sub-data segment.

Referring to FIG. 4, a detailed flow of a method for transmitting data in a short distance according to an embodiment of the present invention is shown. In this embodiment, the receiving terminal and the transmitting terminal support Bluetooth, NFC, and the transmitting terminal. WIFI three short-distance transmission methods, the method may include:

S401: The transmitting terminal divides the data to be transmitted whose data size exceeds a preset threshold into at least one sub-block according to a preset dividing rule, and sets a corresponding sequence identifier for each sub-data segment;

The sequence identifier corresponding to each sub-data segment is used to represent the sequence of the sub-data segments in the data to be transmitted, so that the receiving terminal can splicing all the sub-data segments into complete data to be transmitted according to the sequence identifier.

In this embodiment, the preset threshold may be set to 5M; then the data size exceeds the preset threshold. The data to be transmitted can be caused by the following situations:

Case A: The size of a single file exceeds 5M;

Case B: The total size of the three files exceeds 5M, but the size of each of the three files does not exceed 5M;

Case C: The total size of the three files exceeds 5M, and one of the three files exceeds 5M.

For the above three cases, in the embodiment, the sending terminal divides the data to be transmitted into at least one sub-data segment according to a preset dividing rule, which may be:

For case A, the transmitting terminal may divide a single file into five sub-data segments, and set a sequence identifier for the five sub-data segments;

For case B, the transmitting terminal can respectively treat each of the three files as one sub-data segment, and set the sequence identifier of the sub-data segment according to the file order;

For case C, the sending terminal respectively treats two files whose size does not exceed the preset threshold as a sub-data segment, and divides the file whose size exceeds the preset threshold into three sub-data segments, so that the size of each sub-data segment is Does not exceed the preset threshold.

S402: The transmitting terminal sets a short-distance transmission mode and a transmission sequence corresponding to each sub-data segment according to the size and sequence identifier of each sub-data segment;

In this embodiment, for case A, the sequence identifiers and corresponding sizes of the sub-data segments obtained by the transmitting terminal are (A1, 1M), (A2, 2M), (A3, 2M), (A4, 1M), respectively. (A5, 0.5M); for three short-distance transmission methods, WIFI has the highest transmission rate, NFC is the second, and Bluetooth has the lowest transmission rate; therefore, since A2 and A3 have the largest sub-data segments, they are all 2M, so A2 and A3 are transmitted by WIFI, the transmission order is in the order of sequence identification of sub-data segments, namely A2, A3; and the sizes of A1 and A4 are medium, both are 1M, so A1 and A4 are transmitted by NFC, and the transmission order is in accordance with The sequence of sequence identification of the sub-data segments, that is, A1, A4; A5 has the smallest size of 0.5M, so A5 is transmitted through Bluetooth.

It can be understood that for case B and case C, it can be done in the same way as case A. The short-distance transmission mode and the transmission sequence corresponding to each sub-data segment are set, and details are not described herein again.

Before the step S402, the transmitting terminal may also select the data channel of the short-distance transmission mode with the largest transmission rate in the data channel of the short-distance transmission mode with channel conflict, and block other data channels of the short-distance transmission mode with channel conflict. For example, when both the transmitting terminal and the receiving terminal support another short-distance transmission mode that conflicts with the data channel transmitted by the Bluetooth, the transmitting terminal can shield the data channels of other short-distance transmission modes.

S403: The transmitting terminal simultaneously starts the data channel of the short-distance transmission method, and sends the each sub-data segment and the corresponding sequence identifier to the receiving terminal according to the short-distance transmission mode and the transmission sequence corresponding to each of the sub-data segments;

In this embodiment, for the case A, after the transmitting terminal simultaneously turns on the WIFI, NFC, and Bluetooth data channels, the three data channels can simultaneously transmit the sub-blocks A2, A1, and A5. For cases B and C, the processing is the same as that of case A, and details are not described herein again. In this way, the method of transmitting sub-blocks simultaneously by multiple short-distance transmission methods can fully utilize the data transmission capability of each short-distance transmission mode, and the data transmission is improved compared with the current single-distance transmission method. rate.

S404: After receiving, by the receiving terminal, the at least one sub-data segment and the corresponding sequence identifier sent by the sending terminal according to the short-distance transmission mode and the transmission sequence corresponding to each sub-data segment, the receiving terminal according to the at least one sub-data segment and the corresponding sequence identifier The at least one sub-data segment is spliced into a complete data to be transmitted.

It should be noted that, since the short-distance transmission mode and the transmission sequence corresponding to each sub-data segment are also set by the transmitting terminal, the receiving terminal only needs to receive the sub-data segment corresponding to the mode according to the corresponding short-distance transmission method. For example, for the foregoing case A, the transmitting terminal transmits A2 to the receiving terminal through WIFI. It can be understood that the receiving terminal can only receive the sub-data segment A2 by means of WIFI transmission.

Moreover, the role of the sequence identifier is to characterize the order of the sub-data segments in the data to be transmitted. Therefore, the receiving terminal may splicing all the sub-data segments according to the sequence identifier of the sub-data segments to obtain data to be transmitted. Moreover, the receiving terminal may further determine the transmission loss of the sub-data segment according to the sequence identifier, so that when determining that the sub-data segment transmission is missing, the transmitting terminal may be requested to retransmit the missing sub-data segment.
