Embodiment 1

[0028] A preferred embodiment of the present invention provides a data transmission method, such as figure 1 As shown, the method includes the following steps:

[0029] S102. Search the routing table for the available data transmission path between the data sending terminal and the data receiving terminal, wherein the routing table contains the currently available data transmission path between each terminal, and the data transmission path is between each terminal using a wireless communication protocol The established data transmission path;

[0030] Preferably, the current connection relationship of each terminal is recorded in the routing table. After the data sending terminal and the data receiving terminal are determined, according to the connection relationship of each terminal, the available data transmission path can be obtained in the routing table, for example, data sending The terminal is terminal A, and the data receiving terminal is terminal D, then the available...

Embodiment 2

[0062] Based on the data transmission method provided in Embodiment 1 above, this preferred embodiment provides a data transmission device, Figure 4 A preferred structural block diagram of the device is shown, such as Figure 4 As shown, the device includes: a search unit 402, configured to search the routing table for available data transmission paths between the data sending terminal and the data receiving terminal, wherein the routing table contains currently available data transmission paths between terminals, The data transmission path is a data transmission path established between each terminal using a wireless communication protocol;

[0063] Preferably, the current connection relationship of each terminal is recorded in the routing table. After the data sending terminal and the data receiving terminal are determined, according to the connection relationship of each terminal, the available data transmission path can be obtained in the routing table, for example, data ...

Abstract

The present invention discloses a data transmission method and device, wherein the method includes: searching a routing table for available data transmission paths between a data sending terminal and a data receiving terminal, wherein the routing table contains information currently available between each terminal The data transmission path is a data transmission path established between each terminal using a wireless communication protocol; according to the found data transmission path, the data required to be sent by the data sending terminal is transmitted to the data receiving terminal. The invention effectively solves the problem in the prior art that the terminal is limited by the transmission distance and the transmission protocol when the terminal uses the wireless technology for real-time data transmission, improves the wireless transmission distance, and facilitates data transmission and sharing by users.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method and device. Background technique [0002] In recent years, various wireless technologies have developed rapidly, and wireless networking has brought many benefits to everyone. For example, wireless networking allows people to easily exchange electronic business cards, files or any other information; Personal computer) is connected with external devices such as handheld devices, mobile phones, printers, scanners, fax machines and copiers to establish a personal area network. [0003] One disadvantage of wireless technology is that the transmission distance is limited. For example, terminal A and terminal B can be connected through wireless technology, and terminal B and terminal C can also be connected through wireless technology, but terminal A and terminal C may be connected due to the distance Communication cannot be connected. [0004] At present, the pro...
