[0032] In response to the technical problems in the related art, the present disclosure realizes direct data transmission between two group members who need to communicate without the need for forwarding by an intermediate unit (such as a group leader), thereby greatly improving data transmission efficiency and enhancing user experience.

[0033] At least one embodiment of the present disclosure provides a data transmission method, which is executed by a first member terminal device in a communication group. Figure 1 A schematic diagram showing a flow chart of a data transmission method in an embodiment of the present disclosure is shown. Figure 1 As shown, the method includes steps S100 to S101.

[0034] S100. The first member terminal device receives routing information sent by the group master terminal device, where the routing information includes identity information of the second member terminal device.

[0035] S101. A first member terminal device communicates with a second member terminal device according to identity information of the second member terminal device.

[0036] In an embodiment of the data transmission method disclosed herein, a first member terminal device of the same communication group receives routing information including identity information of a second member terminal device sent by a group master terminal device, and directly communicates with the second member terminal device based on the identity information of the second member terminal device without the need for forwarding by the group master terminal device of the communication group, thereby significantly improving data transmission efficiency, reducing transmission latency, and enhancing user experience.

[0037] At least one embodiment of the present disclosure provides a data transmission method, which is executed by a first member terminal device. Figure 2A Another flow chart of the data transmission method in the embodiment of the present disclosure is shown. Figure 1 Based on the embodiment shown, Figure 2A As shown, the method includes steps S200 to S209.

[0038] S200. The first member terminal device is initialized.

[0039] At the beginning of the self-organizing network test, all terminal devices need to be initialized.

[0040] S201. A first member terminal device sends a search signal to surrounding areas to establish a first communication group with a plurality of terminal devices including a group master terminal device and a second member terminal device.

[0041] After the initialization operation, all terminal devices including the first member terminal device search for other terminal devices in the vicinity and obtain device lists of other terminal devices, thereby completing the establishment of the first communication group, ie, the establishment of the WiFi Direct group. Figure 2B A schematic diagram of the topological structure of the first communication group in the embodiment of the present disclosure is shown as follows: Figure 2B As shown, the group master terminal device is communicatively connected with a plurality of member terminal devices including a first member terminal device, a second member terminal device and a third member terminal device, and communications between the member terminal devices all require forwarding by the group master terminal device.

[0042] S202: The first member terminal device is determined as a member of the first communication group, and the group leader terminal device is the group leader of the first communication group.

[0043] After the first communication group is established, all terminal devices of the first member terminal device obtain the allocation of the device's role (GO or GC) in the group.

[0044] S203. The first group member terminal device sends its name and IP address to the group master terminal device.

[0045] All member terminal devices including the first member terminal device in the first communication group need to send their names and IP addresses to the group master terminal device. For example, all GCs obtain their own IP addresses and names by calling corresponding codes, and send their own device information to the GO device. The group master terminal device establishes a first routing table based on all received names and IP addresses. For example, after the GO device obtains the device information of the GC, it establishes a routing table containing the routing information of all GCs in the group, and sends the device information of itself and other GCs to the addresses contained in the routing table.

[0046] It should be noted that the above routing information is the information of the first routing table, which includes the routing information of all GCs in the group and the routing information of the GO, such as its name and IP address.

[0047] S204. The first member terminal device receives routing information sent by the group master terminal device, where the routing information includes the name and IP address of the second member terminal device.

[0048] S205. The first member terminal device establishes a second routing table according to the routing information. The second routing table includes the names and IP addresses of all member terminal devices of the second member terminal device.

[0049] The first member terminal device establishes a second routing table according to the routing information, for example, according to the names and IP addresses of all GCs in the group, and the second routing table includes the identity information of the second member terminal device, such as the name and IP address.

[0050] It should be noted that both the first routing table and the second routing table include the name and IP address of the group master terminal device and the group member terminal devices of the first communication group. Therefore, the first routing table and the second routing table contain the same information.

[0051] In other embodiments of the present disclosure, the group master terminal device of the first communication group can directly send the first routing table including the group master terminal device of the first communication group and the names and IP addresses of the group member terminal devices to the first group member terminal device, and the first group member terminal device does not need to establish the first routing table again.

[0052] S206. The first member terminal device establishes a second communication group with the second member terminal device according to the name and IP address of the second member terminal device in the second routing table.

[0053] When the first member terminal device needs to communicate with other member terminal devices, such as the second member terminal device, a second communication group is established with the second member terminal device according to the name and IP address of the second member terminal device in the second routing table. For example, when two GCs need to communicate, since both retain each other's information, they can communicate directly in an independent grouping manner, that is, the two communicating GCs form a new group.

[0054] Figure 2C A schematic diagram of the topological structure of the second communication group in the embodiment of the present disclosure is shown as follows: Figure 2C As shown, the first member terminal device and the second member terminal device are connected to each other in communication. Since the first member terminal device is the group master terminal device, the communication between the first member terminal device and the second member terminal device does not need Figure 2B Forwarding by the group master terminal device of the first communication group shown in .

[0055] S207. The first member terminal device is determined as the group owner of the second communication group, and the second member terminal device is determined as a member of the second communication group.

[0056] The first member terminal device is determined as the owner of the second communication group, and the second member terminal device is determined as a member of the second communication group. For example, the first member terminal device and the second member terminal device of the second communication group determine through negotiation that the first member terminal device is the owner of the second communication group, and the second member terminal device is determined as a member of the second communication group.

[0057] S208. The first member terminal device communicates with the second member terminal device.

[0058] S209, the second communication group established between the first member terminal device and the second member terminal device is dissolved, and the first communication group is reconnected.

[0059] After the data transmission between the first member terminal device and the second member terminal device is completed, the second communication group is disbanded, and the first member terminal device and the second member terminal device rejoin the original first communication group to ensure that they can communicate with more terminal devices.

[0060] In an embodiment of the data transmission method disclosed in the present invention, a first member terminal device of the same communication group receives routing information including the name and IP address of a second member terminal device sent by a group master terminal device, and establishes a new communication group with the second member terminal device based on the name and IP address of the second member terminal device to communicate directly without the need for forwarding through the group master terminal device of the communication group, thereby significantly improving data transmission efficiency, reducing transmission latency, and enhancing user experience.

[0068] S402. The group master terminal device receives the name and IP address of the first member terminal device sent by the first member terminal device, and the name and IP address of the second member terminal device sent by the second member terminal device.
