Problems solved by technology

[0003] Although the star topology of the existing personal area network has a simple structure and is easy to maintain; however, since each wearable device in the personal area network must establish a connection with the mobile terminal, the network topology is fixed In some cases, it is not conducive to the transmission of data in the personal area network, and even increases the network overhead; for example: when the number of wearable devices connected to the mobile terminal is relatively large, some urgent messages of some wearable devices cannot Send it to the mobile terminal in time; for another example, when the wearable device B needs to send data to the wearable device A, it must first send the data to the mobile terminal, and then the mobile terminal forwards the data to the wearable device A. Increased network overhead

Embodiment 1

[0209] Figure 4 It shows a flowchart of a data transmission method provided by an embodiment of the present invention, the method is applied to a first wearable device in a personal area network, see Figure 4 As shown, the method may include:

[0210] 101. A first wearable device sends a first broadcast message to a second wearable device.

[0211] Wherein, the first wearable device can be any wearable device connected to the main device (such as a mobile terminal) in the personal area network; the second wearable device can be any wearable device connected to the main device in the personal area network except the first Any wearable device other than a wearable device;

[0212]The first broadcast message is used to indicate that the first wearable device can establish a connection with other wearable devices, and can be sent as a global broadcast to all the personal area network including the second wearable device Wearable device; can also be used as a directed broadcas...

Embodiment 2

[0255] Figure 7 shows another data transmission method provided by the embodiment of the present invention, such as Figure 7 As shown, the following steps may be included:

[0256] 201. A second wearable device receives a first broadcast message sent by a first wearable device.

[0257] The first broadcast message is used to indicate that the first wearable device can establish a connection with other wearable devices, and can be sent as a global broadcast to all the personal area network including the second wearable device wearable devices;

[0258] It can also be sent as a directed broadcast only to the second wearable device.

[0259] 202. The second wearable device sends a second broadcast message to the first wearable device.

[0260] Wherein, the second broadcast message is used to indicate that: the second wearable device has a Bluetooth hub function and can be connected with the first wearable device.

[0261] 203. The second wearable device disconnects from th...

Embodiment 3

[0282] Figure 8 Another data transmission method provided by the embodiment of the present invention is applied when the mobile terminal detects that the service data of the first wearable device is forwarded to the second wearable device through the mobile terminal, in order to reduce network overhead; Such as Figure 8 As shown, the method may include:

[0283] 301. The mobile terminal detects that the service data sent by the first wearable device to the mobile terminal is service data forwarded by the mobile terminal.

[0284] 302. The mobile terminal sends a notification message to the first wearable device; the notification message includes the device identification and address information of the second wearable device, and is used to notify the first wearable device that: the service The final receiving end of the data is the second wearable device.

[0285] It should be noted that the final receiving end in the embodiment of the present invention may refer to a dev...

Abstract

The embodiment of the invention discloses a data transmission method, device and system, relates to the technical field of communication, provides a more flexible network topology structure, and reduces network overhead. The method provided by the embodiment of the present invention includes: the first wearable device sends a first broadcast message to the second wearable device; if the first wearable device detects the second broadcast message sent by the second wearable device , then determine whether the second wearable device supports processing the service data of the first wearable device; if the first wearable device determines that the second wearable device supports processing service data, establish an Connect, and send service data to the second wearable device on the allocated time slot for sending and receiving.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, device and system. Background technique [0002] With the continuous maturity of Internet technology and the miniaturization of hardware, a large number of intelligent wearable devices (such as smart watches, glasses, bracelets, etc.) emerge in an endless stream. It is connected with mobile terminals (such as smartphones, tablet computers, etc.) with a high degree of modernization to form a personal area network (personal area network, PAN) around the human body. In a personal area network, a star topology (such as figure 1 As shown), the mobile terminal is used as the master (master) device, and the wearable device is used as the slave (slave) device. All slave devices are connected to the master device through low-power Bluetooth (bluetooth low energy, BLE). Time-division multiplexing communication method, data is transmitted on the ...
