Exemplarily, the wireless network information is Wi-Fi information, the first terminal device is a mobile phone, and the second terminal device is a smart watch. The watch has a function of network communication transmission. Among them, Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN). Usually, the connection to the wireless local area network is password-protected, but it can also be open, which allows any device within the range of the WLAN to connect. According to the configuration of terminal devices on the market, a typical terminal device can scan about 10 Wi-Fi signals. Among them, the first wireless network information refers to the information of the Wi-Fi signals scanned by the mobile phone within the WLAN range. 2. Wireless network information refers to the information of the Wi-Fi signal scanned by the smart watch within the WLAN range. Assuming that the mobile phone scans 5 Wi-Fi signals, the first wireless signal identifiers of the 5 Wi-Fi signals are AL, B089, A7H6, 87E, and PLI890, and the smart watch scans 6 Wi-Fi signals. The second wireless signal identifiers of the Wi-Fi signal are AL, M09O, A7H6, 87E, PLI890, and VB65 respectively, where the number of the same wireless signal identifiers is 4, specifically AL, A7H6, 87E, and PLI890.

The second wireless signal identifiers of the six Wi-Fi signals are AL, M09O, A7H6, 87E, PLI890, and VB65 respectively, and the number of the same wireless signal identifiers is 2, specifically AL and A7H6, which are less than the number threshold of 3. Whether the mobile phone is far away from the smart watch can be determined according to the first signal strength and the second signal strength corresponding to the same wireless signal identifier.

Specifically, still taking the number of the same wireless signal identifier as 2 and specifically AL and A7H6 as an example, detect the first signal strength of AL in the first wireless signal identifier and the second signal strength of AL in the second wireless signal identifier, Detect the first signal strength of A7H6 in the first wireless signal identifier and the second signal strength of A7H6 in the second wireless signal identifier. For example, the first signal strength of AL is 14, the second signal strength of AL is 3, the first signal strength of A7H6 is 4, and the second signal strength of A7H6 is 13. According to these four signal strength values, it can be seen that AL The difference between the first signal strength and the second signal strength of the A7H6 is 11, and the difference between the first signal strength and the second signal strength of the A7H6 is 9. A signal strength difference threshold of 5 can be preset in the server. The above two signal strength differences are greater than the signal strength Intensity difference threshold, indicating that the phone is far away from the smart watch.

In this embodiment of the present invention, by determining the number of the same wireless signal identifiers among the first wireless signal identifier included in the first wireless network information and the second wireless signal identifier included in the second wireless network information, and judging when When the number of the same wireless signal identifier is greater than the number threshold, it is determined that the first terminal device is not far away from the second terminal device; otherwise, it is further determined according to the first signal strength and second signal strength corresponding to the same wireless signal identifier Whether the first terminal device is far away from the second terminal device. The situation of determining whether the first terminal device is far away from the second terminal device is realized by judging the number of identical wireless signal identifiers in the first wireless network information and the second wireless network information and judging the signal strength of the wireless network information.
