At least one embodiment of the present disclosure provides a data transmission method. The method is performed by a first member terminal device. Fig. 2A shows another flow diagram of a data transmission method in the embodiment of the present disclosure. On the basis of the embodiment shown in fig. 1, as shown in fig. 2A, the method includes steps S200 to S209.
S200, initializing the first member terminal equipment.
When the ad hoc network examination starts, all the terminal devices need to be initialized.
S201, the first member terminal device sends a search signal to the surrounding to establish a first communication group with a plurality of terminal devices including a group main terminal device and a second member terminal device.
After the initialization operation, all the terminal devices including the first member terminal device search other terminal devices existing around and acquire device lists of the other terminal devices, and the establishment of the first communication group, that is, the establishment of the WiFi Direct group is completed. Fig. 2B shows a schematic view of a topology structure of a first communication group in the embodiment of the present disclosure, and as shown in fig. 2B, a group master terminal device is in communication connection with a plurality of group member terminal devices including a first group member terminal device, a second group member terminal device, and a third group member terminal device, and communications between the group member terminal devices all need to be forwarded by the group master terminal device.
S202, the first member terminal device is determined to be a member of the first communication group, and the group master terminal device is a group master of the first communication group.
All terminal devices of the first member terminal device acquire the allocation of roles (GO or GC) of the devices in the group after the first communication group is established.
S203, the first member terminal device sends the name and the IP address to the group main terminal device.
All the member terminal devices in the first communication group, including the first member terminal device, 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. And the group main terminal equipment establishes a first routing table according to all the received names and IP addresses. For example, after the GO device acquires the device information of the GCs, it creates 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.
It should be noted that the routing information is information of the first routing table, and includes routing information of all GCs in the group and routing information of GO, such as names and IP addresses thereof.
S204, the first member terminal equipment receives the routing information sent by the group main terminal equipment, and the routing information comprises the name and the IP address of the second member terminal equipment.

S206, the first member terminal device establishes a second communication group with the second member terminal device according to the name and the IP address of the second member terminal device in the second routing list.
When the first member terminal device needs to communicate with other member terminal devices, for example, the second member terminal device, a second communication group is established with the second member terminal device according to the name and the IP address of the second member terminal device in the second routing table. For example, when two GCs need to communicate with each other, since the two GCs keep the information of the other, they can communicate directly in an independent group manner, i.e. the two GCs communicating with each other form a new group,
fig. 2C is a schematic diagram illustrating a topology structure of a second communication group in an embodiment of the present disclosure, and as shown in fig. 2C, a first member terminal device and a second member terminal device are in communication connection, since the first member terminal device is a group master terminal device, communication between the first member terminal device and the second member terminal device does not need forwarding of the group master terminal device of the first communication group shown in fig. 2B.

And S208, the first member terminal equipment communicates with the second member terminal equipment.
S209, the second communication group established by the first member terminal equipment and the second member terminal equipment is dispersed and is accessed into the first communication group again.
After the data transmission between the first member terminal device and the second member terminal device is completed, the second communication group is disassembled, and the first member terminal device and the second member terminal device are re-accessed into the original first communication group, so that the communication with more terminal devices is ensured.
In the embodiment of the data transmission method disclosed by the invention, the first member terminal equipment of the same communication group receives the routing information which is sent by the group main terminal equipment and comprises the name and the IP address of the second member terminal equipment, and establishes a new communication group with the second member terminal equipment according to the name and the IP address of the second member terminal equipment so as to directly communicate without forwarding through the group main terminal equipment of the communication group, so that the data transmission efficiency is obviously improved, the transmission delay is reduced, and the user experience is improved.
