2 is a flow chart of a method for generating a pairing list according to an embodiment of the invention. The method proposed in this embodiment can be performed by the electronic device 100 of FIG. 1, and the detailed steps of the method are described below with the respective components of FIG.

In step S210, the search module 112_1 can search for at least one first device that belongs to the first subnet with the electronic device 100, and accordingly generates a first list. In an embodiment, the first subnet is, for example, a regional network provided by the first access point, and the different subnets are, for example, regional networks provided by different access points. In this case The search module 112_1 can perform, for example, mDNS, SSDP, or other similar communication protocol to discover or find other first devices that are also served by the first access point. Then, the search module 112_1 may merge the first devices that are explored into the first list. In an embodiment, the first list may record various identification information of each first device, such as an entity identification, an Internet Protocol (IP) address, a unique identifier (for example, It is a Globally Unique Identifier (GUID) or the like, but is not limited thereto.

In addition, in other embodiments, the electronic device 100 may perform step S210 only after being controlled by the user to enter a paired page, but the embodiments of the present invention are not limited thereto.

In step S220, the scanning module 112_2 may scan at least one access point in the vicinity of the electronic device, and accordingly generate a first access point list. In an embodiment, the first access point list may record various identification information of each access point, such as a Service Set Identifier (SSID) and a Basic Service Set Identifier (Basic Service Set Identifier, BSSID), etc., but is not limited to this.

In step S230, the transmission module 112_3 may upload the first access point list to the server, and receive the second list returned by the server. The server is, for example, a data center, a cloud server, or other similar servo device and servo system installed in a cloud network. In an embodiment, the server may receive a list of access points uploaded by other devices in addition to the first access point list from the electronic device 100.

Find a list of access points that are more similar to the first access point list, and merge the corresponding devices into the second list. For convenience of explanation, the device included in the second list will hereinafter be referred to as a second device.

In an embodiment, the server may separately calculate the similarity between the list of access points uploaded by other devices and the first access point list. When an access point list having a similarity with the first access point list is higher than a preset threshold (for example, 50%), the server may define the device corresponding to the access point list as the second device. And included in the second list.

In detail, when two distinct devices have similar access point lists, it means that the two devices are very close to each other. That is, the transmission module 112_3 can find devices (ie, each second device) that are physically similar (eg, located on the same floor) to the electronic device 100 based on the second list returned by the server. Moreover, even if some of the second devices and the electronic device 100 belong to different subnets, the server can find the second devices based on the above teachings and notify the electronic device 100 through the second list.

Thereafter, in step S240, the generating module 112_4 may combine the first list and the second list to generate a pairing list including at least one device to be paired. Specifically, since each first device in the first list may overlap with each second device in the second list, the generating module 112_4 may prevent the repeated devices to be paired from appearing in the pairing list through step S240.

In short, the electronic device 100 can find the first device that belongs to the same subnet as the second device. The list identifies each of the second devices that are physically similar (even though some of the second devices may belong to different subnets from the electronic device 100). From another point of view, when the user wants to pair the electronic device 100 owned by the user with another device (for example, a notebook computer), the method proposed by the embodiment of the present invention can make the electronic device 100 have a higher Opportunity to include this notebook as a paired device in the resulting pairing list, which facilitates subsequent pairing operations.

In an embodiment, the electronic device 100 may further include a speaker 118, and the storage unit 112 may further include a pairing module 112_5 for performing steps S318 to S332, which are specifically described below.

In step S318, the pairing module 112_5 can control the speaker 118 to send a voice message, and determine whether at least one third device responds to the voice message. In an embodiment, the voice message is, for example, a high frequency voice encoded by the pairing module 112_5 to encode identification information (eg, an entity identification code) of the electronic device 100. number. The frequency of the high frequency sound message is, for example, a frequency that the human ear cannot perceive (for example, 25,000 Hz), and the transmission range thereof is, for example, 0.5 to 1 meter, but the embodiment of the present invention is not limited thereto.

In this embodiment, the at least one third device is, for example, a device that the user wants to pair with the electronic device 100, and can listen to the sound message from the speaker 118 through the microphone device.

In an embodiment, when the user wants to pair the electronic device 100 and the at least one third device, the user can switch the two to the pairing page individually. When the at least one third device is in the pairing page, it can turn on the microphone device to listen to the above sound message, but the embodiments of the present invention are not limited thereto.

Since the transmission distance of the voice message is short, if the electronic device 100 receives the response of the at least one third device to the voice message, it means that the distance between the two devices is relatively close, so that it is likely to be the target to be paired with each other. . Therefore, in step S320, the pairing module 112_5 can determine whether the number of at least one third device is 1. If so, the third device is the target to be paired by the electronic device 100. Therefore, the pairing module 112_5 can further define at least one third device as the selected first device to be paired in step S322.

On the other hand, if the number of the at least one third device is not 1, that is, there are multiple possible pairing targets in the vicinity, the pairing module 112_5 may display a pairing list including at least one device to be paired in step S324. To let users get from Select the correct device to be paired. In addition, when the matching module 112_5 does not receive any response in step S318, it may continue to perform step S324 to allow the user to select the correct device to be paired.

Then, in step S326, when the first to-be-paired device of the plurality of devices to be paired is selected, the pairing module 112_5 may determine whether the first device to be paired belongs to the first subnet. If so, the pairing module 112_5 can control the communication unit 114 to send the pairing request to the first paired device in step S330, and wait for the pairing response of the first pairing device for the pairing request. On the other hand, if the first device to be paired does not belong to the first subnet, the pairing module 112_5 may control the communication unit 114 to switch to the second subnet to which the first device to be paired belongs in step S328, and then proceed to the step. S330.

Next, in step S332, when the pairing response indicates that the first to-be-matched device agrees to the pairing request, the pairing module 112_5 may pair with the first paired device.

Moreover, through the mechanism taught in the previous embodiment, even if the two devices belong to different subnets, the method proposed by the embodiment of the present invention can smoothly find out the other party and complete pairing with each other.

In other embodiments, when there is no network connection between the electronic device 100 and the first paired device to be paired, or the network connection environment is not good, the electronic device 100 may output its own identity information as Quick Response (QR) code for the camera module through which the first device to be paired is configured Read. Next, the electronic device 100 may perform the steps S326 to S332 to complete the pairing with the first device to be paired, but the embodiments of the present invention are not limited thereto.

In other embodiments, the present invention can intelligently filter out the paired devices that are closer to the electronic device from the pairing list through an additional mechanism, thereby improving the efficiency of the pairing.
