Problems solved by technology

In addition, the latest data cannot be obtained when accessing, and the sender can only update the old data after sending the data
If there are multiple communication devices, the information between these devices may overlap, and data communication cannot be effectively carried out

Embodiment 1

[0049] Describe the embodiment of the present invention below in conjunction with accompanying drawing.

[0050] figure 1 It is a flow chart showing step by step the operation process of the sending end in the communication method in Embodiment 1 of the present invention. refer to figure 1 , in step S21 (the word "step" is omitted hereinafter), prepare the data for transmission, and divide the data in S22. Data is partitioned vertically by line of a file, subroutine of a program, or function of an application. combine figure 2 A case where a data block is divided from a file will be described. exist figure 2 Among them, (A) is the original file, (B) is the file divided into several blocks, and (C) represents the status of updating the file divided into blocks. Such as figure 2 As shown, the original file (A) composed of multiple sentences is divided into blocks (B) by sentence, and block 4 is updated from "sunny" to "rain" (C).

[0051] In S24, put the data block ...

Embodiment 2

[0055] Embodiment 2 of the present invention will now be described. Figure 4 It is a flow chart for explaining the sending process of the sending end in Embodiment 2. refer to Figure 4 , prepare the data for transmission in S51, and divide the data in S51. These operations are the same as in Example 1. Figure 5 Shows the status of the data divided into chunks. (A) is the original data, (B) is the state of the data divided into three blocks, and (C) is the state of the data obtained by updating the data block when version 1 (Ver.1) is changed to version 2 (Ver.2).

[0056] The version is initialized in S53. At S54, put the data block (send block) to be sent at the head of the block data (corresponding to Figure 5 block 1). In S55, the sending and receiving end sets the address of the sending data. Send the current version in S56. In S57, send the sending block set in S54 and S60 described below to the receiving end. In S58, it is judged whether there is a transmiss...

Embodiment 3

[0059] Embodiment 3 is now described. Figure 7 It is a flow chart for explaining the data sending process of the sender in Embodiment 3. refer to Figure 7 , prepare the data for transmission in S81, and divide the data in S82. The method of dividing data is the same as the above-mentioned embodiment. Figure 8 An example of partitioning data by function is shown. (A) is the original data, which consists of three functions of instruction, calculation, and communication, (B) is the state of the data divided into blocks by function, and (C) is the updated state.

[0060] exist Figure 7 In S83, the version will be initialized. At S84, put the data block (send block) to be sent at the head of the block data (corresponding to Figure 8 block 1). At S85, a transmission number representing information such as the order of transmission data is transmitted. Figure 8 In the example shown, the data blocks carry this transmission number in the order in which they are divided. ...

Abstract

Transmission data is previously divided into a plurality of data blocks S22. If data is updated S26, S29-S31, the update data of the version is transmitted. The receiving side receives and stores data from the start of a block S42, S43. If there is the update data of the version S44, the reception memory is cleared S41 and reception is started once again S41-S43. Thus, all the blocks are received S43-S45, S47, and rearranged to receive prescribed data S46. As a result, in a telecommunication device repeatedly transmitting the same information, an easy to use telecommunication method can be provided.

Description

technical field [0001] In general, the present invention relates to a method for one-way communication for sending long messages based on comparing the transmission rates of a plurality of receiving ends through a communication network or radio waves. In particular, the present invention relates to shortening the waiting time before starting data transmission, A method for efficiently communicating data. Background technique [0002] An example disclosing the communication method contemplated by the present invention is Japanese Patent Laid-Open No. 3-179944. Figure 29A and 29B Explain the principle of conventional data cyclic transmission as described in the literature. The sending end (Fig. 29a) repeatedly sends the start signal, transmission data and termination signal, while the receiving end (Fig. 29b) either receives the data from the middle or waits for the start signal to receive the data from the beginning when receiving the transmission data. If the receiving en...
