Fig. 4 shows a flowchart of a data relay method according to an embodiment of the present application. The method may be applied to the server shown in fig. 1. As shown in fig. 4, the method may include the steps of:

step S401, a communication request message sent by each of at least one relay device is received.

The communication request message is sent to each relay device by a first terminal, the first terminal is a terminal supporting local area network communication, and the relay devices are devices supporting local area network communication and public network communication.

When the first terminal needs to communicate with the outside, the communication request message may be broadcasted to the local area network, as shown in fig. 5, where the communication request message may carry an address of the first terminal and an address of a target terminal that needs to communicate, and after each relay device receives the communication request message carrying the address of the first terminal and the address of the target terminal, the public network signal strength of the local device, the signal strength of the local device relative to the first terminal, and the local address of the local device may be determined. Further, as shown in fig. 6, each relay device may add the local public network signal strength and the local signal strength relative to the first terminal, the address of the local device to the communication request message sent by the first terminal, and send the communication request message after adding the information to the server, where the server may receive the communication request message sent by each relay device in the at least one relay device.

Step S402, determining a target relay device from at least one relay device according to the communication request message sent by each relay device, and determining a relay path.

In an alternative embodiment, the method for determining the target relay device from at least one relay device and determining the relay path by the server according to the communication request message sent by each relay device, as shown in fig. 7, may include the following steps:

in step S4021, a relay device having a public network signal strength greater than a set strength threshold value among at least one relay device is used as a candidate relay device.

The server may use, as a candidate relay device, a relay device having a public network signal strength greater than a set strength threshold, where the set strength threshold may be set as required, and may be, for example, -80dBm.

In this step, the relay device with the public network signal strength greater than the set strength threshold value in at least one relay device is used as a candidate relay device, so as to ensure the communication quality between the relay device and the second terminal in the public network environment, and if the server determines that the second terminal is a terminal in the local area network environment, all the relay devices can be used as candidate relay devices.

In some embodiments, if there are a plurality of candidate relay devices, after obtaining the candidate relay device, the candidate relay device having the highest signal strength with respect to the first terminal among the candidate relay devices may be regarded as the target relay device.

In other embodiments, if there is only one candidate relay device, the relay device may be directly regarded as the target relay device.

In step S4023, a relay path is determined according to the address of the target relay device, the address of the first terminal, and the address of the second terminal.

After determining the target relay device, the server may determine a relay path according to the address of the target relay device, the address of the first terminal, and the address of the second terminal. As shown in fig. 8, the relay path includes an address of the first terminal, an address of the target relay device, and an address of the second terminal.

When the first terminal is an initiator of communication data, the method for the first terminal to communicate with the second terminal may include the following steps, as shown in fig. 9:

in step S901, the first terminal determines a relay path based on the addresses of the first terminal and the second terminal.

When the first terminal needs to communicate with the second terminal, the first terminal may determine a relay path required for communicating with the second terminal, where the relay path is sent by the target relay device to the first terminal when the first terminal broadcasts the communication request, and a method for determining the relay path is described in detail above and is not described herein.

In step S902, the first terminal transmits communication data to the target relay device according to the relay path.

The first terminal may send communication data to the target relay device according to the address of the target relay device in the relay path, where the communication data carries the address of the second terminal.

In step S903, the target relay apparatus transmits communication data to the second terminal.

After receiving the communication data sent by the first terminal, the target relay device can forward the communication data sent by the first terminal to the second terminal according to the address of the second terminal carried in the communication data, thereby completing the function of data relay.

When the second terminal is an initiator of communication data, the method for the second terminal to communicate with the first terminal may include the following steps, as shown in fig. 10:

in step S1001, the second terminal determines a relay path based on the addresses of the second terminal and the first terminal.

When the second terminal needs to communicate with the first terminal, the second terminal may determine a relay path required when communicating with the first terminal.

In step S1002, the second terminal transmits communication data to the target relay device according to the relay path.

The second terminal may send communication data to the target relay device according to the address of the target relay device in the relay path, where the communication data carries the address of the first terminal.

In step S1003, the target relay apparatus transmits communication data to the first terminal.

After receiving the communication data sent by the second terminal, the target relay device can forward the communication data sent by the second terminal to the first terminal according to the address of the first terminal carried in the communication data, thereby completing the function of data relay.
