Description

Bluetooth back connection method, system, electronic equipment, server and storage medium

Technical Field

The present application relates to the field of Bluetooth (BT) technology, and in particular, to a BT backhaul method, system, electronic device, server, and storage medium.

Background

With the popularization of bluetooth technology, more and more electronic devices have BT functions. When two electronic devices with BT function (e.g. electronic device 1 and electronic device 2) are enabled to perform bluetooth function, a bluetooth connection may be established for communication. When the distance between the two electronic apparatuses is not within the BT communication range for some reason, for example, the BT connection of the two electronic apparatuses is disconnected. After the BT connection of two electronic devices is disconnected, if the distance of the two electronic devices is within the BT communication range again, since the BT information of each other has been saved in the process of the previous connection, the BT reconnection can be performed using the saved BT information.

In some BT backhaul schemes, when the electronic apparatus 1 disconnects BT from the electronic apparatus 2, the electronic apparatus 1 may record the location a of the electronic apparatus 2 (i.e., the location of the electronic apparatus 2 when BT is disconnected from the electronic apparatus 1 this time). Then, the electronic apparatus 1 initiates a BT reconnection to the electronic apparatus 2 when detecting that the electronic apparatus 2 returns to the above-described location a (or the vicinity of the location a).

However, the location of both electronic devices may change. Using the above scheme requires that the two electronic devices must be in (or near) position a to successfully connect back. In the following two scenarios, the electronic apparatus 1 and the electronic apparatus 2 cannot establish the BT connection through the BT backhaul connection. For example, when the electronic device 1 and the electronic device 2 move to the same location b, with the above scheme, the two electronic devices cannot automatically initiate a BT backhaul and thus cannot establish a BT connection. For another example, when the electronic device 1 moves to the location c which is very far away from the location a and the electronic device 2 returns to the location a again, the electronic device 1 initiates a BT loopback connection with the electronic device 2, and the BT connection cannot be established because the two electronic devices are far away.

In summary, according to the scheme, the success rate of establishing the BT connection by the two electronic devices through the BT backhaul is low.

Disclosure of Invention

Embodiments of the present application provide a BT reconnection method, system, electronic device, server, and storage medium, which are used to improve a success rate of establishing a BT connection between two electronic devices through BT reconnection.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, a BT reconnection method is provided, where the method includes: after the first electronic device is disconnected from the second electronic device by the BT connection, the first electronic device periodically sends the position information of the first electronic device to the cloud server. Then, the cloud server receives the position information from the first electronic device and forwards the position information of the first electronic device to the second electronic device. The second electronic equipment receives the position information of the first electronic equipment from the cloud server; and the second electronic equipment judges whether the third electronic equipment is positioned in the first electronic fence or not according to the position information of the third electronic equipment. And if the third electronic equipment is positioned in the first electronic fence, performing BT loop connection between the second electronic equipment and the first electronic equipment.

The third electronic device is a first electronic device, and the first electronic fence takes the position of the second electronic device as a center; or, the third electronic device is the second electronic device, and the first electronic fence is centered on the position indicated by the position information of the first electronic device.

It can be understood that, after receiving the location information of the first electronic device, the second electronic device determines whether its location is within the first electronic fence centered around the location of the first electronic device, or whether the location of the first electronic device is within the first electronic fence centered around the location of the second electronic device. If the position of the second electronic device is located in the first electronic fence centered on the position of the first electronic device, or the position of the first electronic device is located in the first electronic fence centered on the position of the second electronic device, the second electronic device can perform BT loop connection with the first electronic device.

Whether the position of the second electronic device is located in the first electronic fence centered on the position of the first electronic device or the position of the first electronic device is located in the first electronic fence centered on the position of the second electronic device, the distance between the second electronic device and the first electronic device is within a certain range. For example, if the distance between the second electronic device and the first electronic device is within the BT communication range, the second electronic device and the first electronic device may successfully establish the BT connection through the BT backhaul connection. For another example, after the distance between the second electronic device and the first electronic device exceeds the BT communication range and the distance between the second electronic device and the first electronic device approaches the BT communication range, and the BT backhaul connection is performed between the second electronic device and the first electronic device, the BT connection may be quickly established between the second electronic device and the first electronic device through the BT backhaul connection once the distance between the second electronic device and the first electronic device is reduced to be within the BT communication range.

In summary, by using the method, the success rate of the BT connection established by the first electronic device and the second electronic device through the BT backhaul connection can be improved.

In one possible implementation, the method further includes: and if the third electronic equipment is positioned outside the first electronic fence, the second electronic equipment and the first electronic equipment do not carry out BT loop connection.

It is to be understood that if the third electronic device is outside the first electronic fence, it indicates that the location of the second electronic device is outside the first electronic fence centered on the location of the first electronic device, or that the location of the first electronic device is outside the first electronic fence centered on the location of the second electronic device. Whether the position of the second electronic device is outside the first electronic fence centered on the position of the first electronic device or the position of the first electronic device is outside the first electronic fence centered on the position of the second electronic device, it means that the distance between the first electronic device and the second electronic device is greater than the distance from the center of the first electronic fence to the boundary of the first electronic device. If the distance from the center of the first electronic fence to the boundary of the first electronic device is equal to the BT communication distance setting, the distance between the first electronic device and the second electronic device is known to exceed the BT communication distance. At this time, the second electronic device may not BT loop connection with the first electronic device. Therefore, the BT loop-back connection failure of the first electronic device and the second electronic device caused by the fact that the first electronic device is too far away from the second electronic device is avoided, and therefore the power consumption of the second electronic device and/or the power consumption of the first electronic device can be reduced.

In another possible implementation manner, if the third electronic device is located in the first electronic fence, the BT loop connection between the second electronic device and the first electronic device includes: and if the third electronic equipment is positioned in the first electronic fence, performing BT back connection between the second electronic equipment and the first electronic equipment according to a first preset frequency. The method further comprises the following steps: and if the third electronic equipment is positioned outside the first electronic fence and in the second electronic fence, performing BT back connection between the second electronic equipment and the first electronic equipment according to a second preset frequency.

The center of the second electronic fence is superposed with the center of the first electronic fence, and the radius of the second electronic fence is greater than that of the first electronic fence; the first predetermined frequency is greater than the second predetermined frequency.

It is understood that the BT communication distance of the electronic devices in the open area where the shield is less is generally larger than the BT communication distance of the electronic devices in the area where the shield is much. That is, the BT communication distance is not a fixed value. The number of obstructions in the area of the electronic device may also affect the amount of BT communication distance. Thus, in addition to a first electronic fence centered on the location of the first electronic device or the second electronic device, the second electronic device can also set a second electronic fence. The center of the second electronic fence coincides with the center of the first electronic fence, and the area of the second electronic fence is larger than the area of the first electronic fence.

Second, the second electronic device can set the distance from the center of the first electronic fence to the boundary of the first electronic device (e.g., the radius of the first electronic fence), so as to ensure that the two electronic devices in the first electronic fence are not substantially affected by the obstruction, and the BT connection can be established. The second electronic device may set a distance from a center of the second electronic fence to a boundary of the second electronic device (e.g., a radius of the second electronic fence) to ensure that the two electronic devices within the second electronic fence are affected by the number of obstructions, and that the BT connection may be established or may not be established. Further, if the third electronic device is within the first electronic fence, it may be determined that the first electronic device and the second electronic device may successfully establish the BT connection. Therefore, the second electronic device and the first electronic device can perform BT loopback according to a higher first preset frequency, so as to ensure that the first electronic device and the second electronic device quickly establish BT connection through BT loopback.

Secondly, if the third electronic device is located outside the first electronic fence and inside the second electronic fence, it can be known that the first electronic device and the second electronic device are likely to successfully establish the BT connection, for example, when there are few obstructions inside the second electronic fence, the first electronic device and the second electronic device can successfully establish the BT connection. Thus, the second electronic device may BT-loop with the first electronic device. However, the first electronic device and the second electronic device may not be able to establish the BT connection, for example, when there are many obstacles in the second electronic fence, the BT connection may not be established between the first electronic device and the second electronic device. Therefore, the second electronic device and the first electronic device can perform BT backhaul according to a second lower preset frequency. Therefore, power consumption can be reduced, and BT connection can be automatically established between the first electronic device and the second electronic device through BT back connection under the condition that shielding objects in the second electronic fence are less.

In another possible implementation manner, the method further includes: and if the third electronic equipment is positioned outside the second electronic fence, the second electronic equipment and the first electronic equipment do not carry out BT loop connection.

It can be understood from the above analysis that when the third electronic device is located outside the first electronic fence and the third electronic device is located inside the second electronic fence, the first electronic device and the second electronic device may or may not establish a BT connection due to the number of the shielding objects inside the second electronic fence. Then, when the third electronic device is outside the second electronic fence, the first electronic device and the second electronic device are too far apart, and the BT connection cannot be established. At this time, the second electronic device does not perform BT back connection with the first electronic device, which can reduce the number of BT returns

For example, when there are many obstructions in the second electronic fence, the two cannot establish a BT connection. Therefore, the second electronic device and the first electronic device can perform BT loopback according to a second lower preset frequency. Therefore, the BT loop-back connection failure of the first electronic device and the second electronic device caused by the fact that the first electronic device is too far away from the second electronic device is avoided, and therefore the power consumption of the second electronic device and/or the power consumption of the first electronic device can be reduced.

In another possible implementation manner, after the first electronic device disconnects BT from the second electronic device, periodically sending location information of the first electronic device to the cloud server includes: after the first electronic device is disconnected from the second electronic device, the location information of the first electronic device can be sent to the cloud server according to the third preset frequency in the first period and the fourth preset frequency in the second period according to the historical BT connection information of the first electronic device and the second electronic device.

The BT history connection information is used for recording the time period of the BT connection disconnection between the first electronic device and the second electronic device for multiple times. The first period is a period in which the first electronic device disconnects BT connection from the second electronic device a plurality of times, and the second period is different from the first period. The third predetermined frequency is less than the fourth predetermined frequency.

It can be understood that, when the user uses the first electronic device and the second electronic device, due to the behavior habit of the user, there may occur a period of regularly disconnecting the BT connection of the first electronic device and the second electronic device, and also a period of sporadically disconnecting the BT connection of the first electronic device and the second electronic device.

Since the period in which the BT connection of the first electronic device and the second electronic device occurs regularly, it may be determined that the first electronic device and the second electronic device remain BT connected for a certain period of time. However, in the accidentally occurring period of time when the first electronic device and the second electronic device are disconnected from the BT connection, the first electronic device and the second electronic device may re-perform the BT connection at any time because the distance between the first electronic device and the second electronic device is reduced to be smaller than the BT communication distance. Therefore, during an occasional period in which the first electronic device and the second electronic device disconnect the BT connection, the first electronic device may transmit the location information of the first electronic device to the cloud server at a higher frequency (e.g., a fourth preset frequency). Therefore, when the distance between the first electronic device and the second electronic device is reduced to be smaller than the BT communication distance at any time, the first electronic device and the second electronic device can quickly execute the BT back connection process so as to quickly realize BT connection. In a period when the BT connection between the first electronic device and the second electronic device is regularly disconnected, the first electronic device may transmit the location information of the first electronic device to the cloud server at a lower frequency (e.g., a third preset frequency), which may reduce power consumption of the first electronic device.

In a second aspect, a BT reconnection method is provided, the method comprising: after the second electronic device is disconnected from the first electronic device by BT, the second electronic device may periodically acquire the location information of the first electronic device from the cloud server. Then, the second electronic equipment judges whether the third electronic equipment is located in the first electronic fence or not according to the position information of the third electronic equipment; and if the third electronic equipment is positioned in the first electronic fence, performing BT loop connection between the second electronic equipment and the first electronic equipment.

In one possible implementation, the method further includes: and if the third electronic equipment is positioned outside the first electronic fence, the second electronic equipment and the first electronic equipment do not carry out BT back connection.

In a third aspect, a BT reconnection method is provided, which includes: after the first electronic device is disconnected from the second electronic device by the BT connection, the cloud server can periodically acquire the position information of the first electronic device and the position information of the second electronic device.

And if the third electronic equipment is located in the first electronic fence, the cloud server controls the second electronic equipment to perform BT loop connection with the first electronic equipment.

The third electronic device is the first electronic device, and the first electronic fence takes the position indicated by the position information of the second electronic device as the center; or, the third electronic device is the second electronic device, and the first electronic fence is centered on the position indicated by the position information of the first electronic device.

In one possible implementation, the method further includes: and if the third electronic equipment is positioned outside the first electronic fence, the cloud server controls the second electronic equipment and the first electronic equipment not to carry out BT back connection.

In another possible implementation manner, if the third electronic device is located in the first electronic fence, the controlling, by the cloud server, the BT loopback between the second electronic device and the first electronic device includes: and if the third electronic equipment is located in the first electronic fence, the cloud server controls the second electronic equipment and the first electronic equipment to carry out BT back connection according to a first preset frequency. The method further comprises the following steps: and if the third electronic equipment is positioned outside the first electronic fence and in the second electronic fence, the cloud server controls the second electronic equipment and the first electronic equipment to carry out BT (bit rate) link according to a second preset frequency.

In another possible implementation manner, the method further includes: and if the third electronic equipment is positioned outside the second electronic fence, the cloud server controls the second electronic equipment and the first electronic equipment not to carry out BT back connection.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specified.

Currently, two electronic apparatuses having a BT function (e.g., the electronic apparatus 1 and the electronic apparatus 2) can save BT information of each other when BT connection is established for the first time. After the two electronic devices are disconnected from the BT, the BT backhaul connection can be performed using the saved BT information. Through the BT backhaul, the two electronic devices may automatically establish a BT connection. Wherein either one of the two electronic devices may initiate a BT backhaul. The process of the electronic device 1 initiating the BT reconnection will be described below by taking the electronic device 1 initiating the BT reconnection as an example.

In the first related scheme, when the bluetooth function is turned on, the electronic device 1 initiates a BT loopback at a certain frequency for a certain time period from the moment when the electronic device 1 disconnects the BT from the electronic device 2. Then, after a certain period of time, the electronic apparatus 1 decreases the frequency of initiating the BT backhaul one or more times again, and initiates the BT backhaul at a lower frequency until the electronic apparatus 1 establishes a BT connection with another electronic apparatus (e.g., the electronic apparatus 2).

Exemplarily, taking the electronic apparatus 1 as a watch having a BT function as an example, the watch initiates a BT loopback every 15 seconds(s) within 10 minutes (min) from the time of disconnecting the BT connection with the electronic apparatus 2 when the BT function is turned on. After 10min, BT reconnect was initiated every 55s within 7 min. After 17min, a BT loopback is initiated every 59s until the watch establishes a BT connection with other electronic devices.

With this first related scheme, if the BT connection disconnection time period between the electronic apparatus 1 and the electronic apparatus 2 is long, the BT reconnection speed with the electronic apparatus 2 becomes slow. Thereby reducing the speed at which the electronic apparatus 1 automatically establishes a BT connection with the electronic apparatus 2 and increasing the time for the user to wait for the electronic apparatus 1 to automatically establish a BT connection with the electronic apparatus 2.

In the second related solution, when the electronic apparatus 1 disconnects BT from the electronic apparatus 2, the electronic apparatus 1 may record the location a of the electronic apparatus 2 (i.e., the location of the electronic apparatus 2 when BT connection is disconnected from the electronic apparatus 1 this time). Then, the electronic apparatus 1 initiates a BT loopback with respect to the electronic apparatus 2 upon detecting that the electronic apparatus 2 returns to the above location a (or the vicinity of location a).

Illustratively, taking the electronic device 1 as a mobile phone and the electronic device 2 as a smart watch as an example, as shown in fig. 1, when the smart watch is located at a position a, the mobile phone and the smart watch are disconnected from BT connection because the distance between the mobile phone and the smart watch exceeds the BT communication range (e.g., the BT communication range centered at the position a in fig. 1). Then, the cell phone and the smart watch may move to the same location b, and the location b is far away from the location a. At this time, since the position b where the smart watch is located is not near the position a, by adopting the second related scheme, the mobile phone cannot automatically initiate BT loopback, and further cannot automatically establish BT connection with the smart watch.

Alternatively, the handset may move to location c, which is a significant distance from location a, and the smart watch may revert to location a again. At this point, the cell phone may initiate a BT loopback to the smartwatch. However, since the distance between the position c where the mobile phone is located and the position a where the smart watch is located is far away and exceeds the BT communication range, the BT connection cannot be established between the mobile phone and the smart watch.

In summary, the success rate of establishing the BT connection by the BT backhaul connection by the two electronic devices using the correlation scheme is low.

In view of the foregoing problems, embodiments of the present application provide a BT backhaul connection method, which can improve the speed and success rate of two electronic devices establishing a BT connection through BT backhaul connection. After the electronic apparatus 1 and the electronic apparatus 2 disconnect the BT connection, the electronic apparatus 1 may periodically transmit the location information of the electronic apparatus 1 to the cloud server. The cloud server forwards the location information of the electronic device 1 to the electronic device 2. The electronic device 2 can determine whether its own location is within the electronic fence centered on the location of the electronic device 1, or whether the location of the electronic device 1 is within the electronic fence centered on the location of the electronic device 2. If the position of the electronic device 2 is within the electronic fence centered on the position of the electronic device 1, or the position of the electronic device 1 is within the electronic fence centered on the position of the electronic device 2, the electronic device 2 can BT-reconnect with the electronic device 1.

Whether the position of the electronic device 2 is located in the electronic fence centered on the position of the electronic device 1 or the position of the electronic device 1 is located in the electronic fence centered on the position of the electronic device 2, it indicates that the distance between the electronic device 2 and the electronic device 1 is within a certain range, for example, the distance between the electronic device 2 and the electronic device 1 is within the BT communication range, and the electronic device 2 and the electronic device 1 can successfully establish the BT connection through the BT backhaul connection. For another example, when the distance between the electronic apparatus 2 and the electronic apparatus 1 is beyond the BT communication range but is close to the BT communication range, the electronic apparatus 2 and the electronic apparatus 1 perform BT backhaul connection, and when the distance between the electronic apparatus 2 and the electronic apparatus 1 is reduced to be within the BT communication range, the electronic apparatus 2 and the electronic apparatus 1 can quickly establish BT connection through the BT backhaul connection.

In summary, the method can improve the success rate of BT connection establishment by the two electronic devices, namely the electronic device 1 and the electronic device 2, through BT backhaul connection. Secondly, when the distance between the electronic apparatus 2 and the electronic apparatus 1 is within a certain range (e.g., BT communication range), the electronic apparatus 2 and the electronic apparatus 1 can perform BT backhaul at a higher frequency. This may increase the speed at which the electronic apparatus 1 automatically establishes a BT connection with the electronic apparatus 2.

In some examples, the electronic device (the electronic device 1 or the electronic device 2) may be a mobile phone, a tablet computer, a handheld computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a wearable device, or other electronic devices with BT function. The embodiment of the present application does not limit the specific form of the electronic device.

Of course, it should be understood that the above fig. 2 is only an exemplary illustration of the electronic device 1 in the form of a mobile phone. If the electronic device 1 is in the form of a tablet computer, a handheld computer, a PC, a PDA, a wearable device (e.g., a smart watch, a smart bracelet), or other devices, the structure of the electronic device 1 may include fewer structures than those shown in fig. 2, or may include more structures than those shown in fig. 2, and is not limited herein. Similarly, the electronic device 2 may be a mobile phone as shown in fig. 2, or other device forms. If the electronic device 2 is in another device form, the structure of the electronic device 2 may include fewer structures than those shown in fig. 2, or may include more structures than those shown in fig. 2, and is not limited herein.

In this embodiment, after the electronic device 1 and the electronic device 2 are disconnected from the BT, the electronic device 1 may send the location information of the electronic device 1 to the electronic device 2 through the cloud server. Then, the electronic device 2 may determine whether the electronic device 3 is within the first electronic fence based on the location information of the electronic device 1 and the location information of the electronic device 2 to determine whether the electronic device 2 is BT-linked with the electronic device 1. The electronic device 3 may be the electronic device 1 or the electronic device 2. The first electronic fence is established by taking the position of the electronic device 1 or the position of the electronic device 2 as a center, and is used for judging whether the distance between the electronic device 1 and the electronic device 2 is smaller than the distance from the center of the first electronic fence to the boundary of the first electronic device.

In some embodiments, as shown in fig. 3, electronic device 1 may be a cell phone 31 (e.g., cell phone 200 described above), electronic device 2 may be a smart watch 32, and electronic device 3 may be electronic device 1 (i.e., electronic device 3 is cell phone 31). The smart watch 32 may be provided with a first electronic fence, which may be a bounded area centered around the location of the smart watch 32. The smart watch 32 may determine whether the cell phone 31 is within the first electronic fence. If the cell phone 31 is located in the first electronic fence, which means that the distance between the cell phone 31 and the smart watch 32 is smaller than the distance between the center of the first electronic fence and the boundary of the first electronic device, for example, the distance between the cell phone 31 and the smart watch 32 is smaller than the BT communication distance, the smart watch 32 and the cell phone 31 may perform BT backhaul. Wherein the cell phone 31 shown in fig. 3 is not inside the first electronic fence.

The BT reconnection method provided in the embodiment of the present application is described in detail below with reference to fig. 3. As shown in fig. 4, the method may include S401-S406.

S401, after the BT connection between the mobile phone 31 and the smart watch 32 is disconnected, periodically sending the location information of the mobile phone 31 to the cloud server.

The mobile phone 31 may disconnect the BT connection from the smart phone 32 when the BT function of the mobile phone 31 is turned on, for example, because the distance between the mobile phone 31 and the smart watch 32 exceeds the BT communication distance. Then, the handset 31 may periodically acquire the location information of the handset 31 and transmit the location information of the handset 31 to the cloud server.

The position of the mobile phone 31 is dynamically changed, so that the mobile phone 31 can periodically acquire updated position information of the mobile phone 31 and send the updated position information to the cloud server.

For example, the mobile phone 31 may obtain the position information of the mobile phone 31 through the GNSS provided by the wireless communication module. The handset 31 may then send the location information of the handset 31 to a cloud server over a cellular network (e.g., GSM network, CDMA network, LTE).

In some embodiments, when the user uses the mobile phone 31 and the smart watch 32, due to the habit of behavior of the user, there may be a period of regularly disconnecting the BT connection between the mobile phone 31 and the smart watch 32, and a period of sporadically disconnecting the BT connection between the mobile phone 31 and the smart watch 32. For example, if the user is in a meeting during one working period of each week, and the user does not carry the cell phone 31 but only carries the smart watch 32 during the meeting, the distance between the cell phone 31 and the smart watch 32 during the meeting may exceed the BT communication distance. Which in turn causes the handset 31 and the smart watch 32 to disconnect the BT connection. That is, the user may have the BT connection between the cell phone 31 and the smart watch 32 disconnected during the weekly work hours.

Since the period in which the BT connection of the cellular phone 31 and the smart watch 32 is disconnected occurs regularly, it can be determined that the cellular phone 31 and the smart watch 32 remain disconnected from the BT connection for a certain period of time. During the period of time when the BT connection between the cellular phone 31 and the smart watch 32 is disconnected, which happens occasionally, the cellular phone 31 and the smart watch 32 may be in BT connection again at any time because the distance between the two is reduced to be smaller than the BT communication distance. Therefore, during the period when the BT connection between the cell phone 31 and the smart watch 32 is disconnected accidentally, the cell phone 31 may transmit the location information of the cell phone 31 to the cloud server at a higher frequency (e.g., a preset frequency 1). Therefore, when the distance between the mobile phone 31 and the smart watch 32 is reduced to be smaller than the BT communication distance at any time, the mobile phone 31 and the smart watch 32 can quickly execute the BT loopback process to quickly realize BT connection. During the time period when the BT connection between the cell phone 31 and the smart watch 32 is regularly disconnected, the cell phone 31 may transmit the location information of the cell phone 31 to the cloud server at a lower frequency (e.g., preset frequency 2), which may reduce power consumption of the cell phone 31.

Specifically, after the BT connection between the cell phone 31 and the smart watch 32 is disconnected, the location information of the cell phone 31 may be sent to the cloud server according to the BT historical connection information between the cell phone 31 and the smart watch 32 and the preset frequency 1 in the first period, and the location information of the cell phone 31 may be sent to the cloud server according to the preset frequency 2 in the second period.

The BT history connection information is used to record a period of time when the mobile phone 31 and the smart watch 32 are disconnected from BT multiple times. The first period is a period in which the BT connection between the cellular phone 31 and the smart watch 32 is disconnected a plurality of times, and the second period is different from the first period. The predetermined frequency 1 is less than the predetermined frequency 2.

In some embodiments, after the cell phone 31 and the smart watch 32 are disconnected from the BT connection, in addition to the cell phone 31 periodically transmitting the location information of the cell phone 31 to the cloud server, the cell phone 31 and the smart watch 32 may not perform the BT loopback, that is, the cell phone 31 does not perform the BT loopback for the smart watch 32, and the smart watch 32 does not perform the BT loopback for the cell phone 31.

It is understood that if the distance between the cell phone 31 and the smart watch 32 is too long, for example, exceeds the BT communication distance, the cell phone 31 disconnects the BT connection from the smart watch 32. It is known that the BT connection cannot be established when the cell phone 31 and the smart watch 32 perform BT loopback. Therefore, the cell phone 31 and the smart watch 32 do not perform BT loopback. This may avoid power consumption of the electronic device (including the handset 31 and/or the smart watch 32) due to an invalid BT backhaul.

S402, the cloud server receives the location information from the mobile phone 31, and forwards the location information of the mobile phone 31 to the smart watch 32.

Each time the cloud server receives the location information of the cell phone 31, the location information may be forwarded to the smart watch 32.

For example, the cloud server may send the location information of the cell phone 31 to the smart watch 32 through a cellular network.

S403, the smart watch 32 receives the location information of the mobile phone 31 from the cloud server.

The smart watch 32 may first obtain the location information of the mobile phone 31 each time the location information is received. The smart watch 32 determines the distance between the cellular phone 31 and the smart watch 32 based on the received location information of the cellular phone 31 and the location information of the smart watch.

The position of the smart watch 32 is dynamically changed, and each time the smart watch 32 receives updated position information of the mobile phone 31, the updated position information of the smart watch itself is also obtained.

For example, the smart watch 32 may acquire the location information of the mobile phone 31 through GNSS provided by the wireless communication module. For example, the smart watch 32 acquires the position information of the cell phone 31 by GPS.

S404, the smart watch 32 judges whether the mobile phone 31 is in the first electronic fence or not according to the position information of the mobile phone 31; the first electronic fence is centered on the location of the smart watch 32.

Wherein, the position of the smart watch 32 and the position of the mobile phone 31 are dynamically changed; thus, the location of the first electronic fence that the smart watch 32 sets up may also vary. The first electronic fence may be centered on the location of the smart watch 32, and the location of the first electronic fence may change as the location of the smart watch 32 changes.

Second, if the cell phone 31 is inside the first electronic fence, it means that the location of the cell phone 31 and the location of the smart watch 32 (i.e. the center of the first electronic fence) are both inside the first electronic fence, i.e. the distance between the cell phone 31 and the smart watch 32 does not exceed the distance from the center of the first electronic fence to the boundary of the first electronic device. Therefore, the smart watch 32 may set the distance from the center of the first electronic fence to the boundary of the first electronic device according to the BT communication distance so that the distance between the cell phone 31 and the smart watch 32 within the first electronic fence is smaller than the BT communication distance or close to the BT communication distance.

Further, if the cell phone 31 is in the first electronic fence, which means that the distance between the cell phone 31 and the smart watch 32 is the same as or close to the BT communication distance, the smart watch 32 and the cell phone 31 may perform BT loopback, i.e., execute S405. Therefore, when the distance between the mobile phone 31 and the smart watch 32 is smaller than the BT communication distance, the BT connection between the smart watch 32 and the mobile phone 31 can be quickly realized through the BT backhaul connection. If the cell phone 31 is not located in the first electronic fence, the smart watch 32 and the cell phone 31 may not BT connect, i.e., execute S406.

In some embodiments, the smart watch 32 may set the distance from the center of the first electronic fence to the boundary of the first electronic device according to the BT communication distance.

Illustratively, as shown in fig. 3, the first electronic fence may be a circular area centered at the location of the smart watch 32 and having a radius of a preset length. The preset length may be equal to or close to the BT communication distance.

It should be noted that the first electronic fence may be a square or an oval in addition to the circle shown in fig. 3, and the shape of the first electronic fence is not limited in the embodiment of the present application.

In some embodiments, in the case where the first electronic fence is circular, the smart watch 32 may calculate the distance between the cell phone 31 and the smart watch 32 according to the location information of the cell phone 31 and the location information of the smart watch 32. If the distance is less than or equal to the radius of the first electronic fence, it is determined that the cell phone 31 is inside the first electronic fence. If the distance is greater than the radius of the first electronic fence, it is determined that the cell phone 31 is not inside the first electronic fence.

S405, the smart watch 32 and the cell phone 31 perform BT backhaul.

The smart watch 32 may BT-loop the cell phone 31, or the smart watch 32 controls the cell phone 31 to BT-loop the smart watch 32.

In some embodiments, the smart watch 32 may BT-loop the cell phone 31 according to a BT-loop frequency preset in the smart watch 32. For example, the smart watch 32 BT-loops the cell phone 31 at the maximum frequency among BT-loop frequencies preset in the smart watch 32.

In other embodiments, the smart watch 32 may send a first instruction to the cloud server, the first instruction being used to instruct the cell phone 31 to BT-reconnect the smart watch 32. The cloud server receives the first instruction from the smart watch 32 and forwards the first instruction to the cell phone 31. The handset 31 then makes a BT loopback to the smart watch 32.

The mobile phone 31 may perform BT reconnection on the smart watch 32 according to a preset BT reconnection frequency in the mobile phone 31. For example, the smart watch 32 performs BT backhaul at the maximum frequency among BT backhaul frequencies preset in the cell phone 31.

Illustratively, the smart watch 32 may send the first instruction to a cloud server over a cellular network.

Illustratively, the cloud server may forward the first instruction to the handset 31 over the cellular network.

S406, the smart watch 32 and the cell phone 31 do not perform BT loopback.

If the cell phone 31 is not in the first electronic fence, it means that the cell phone 31 is far from the center of the first electronic fence (i.e., the smart watch 32), and may exceed the BT communication distance. Therefore, the smart watch 32 and the cell phone 31 may not perform BT backhaul. Thus, the BT connection failure between the mobile phone 31 and the smart watch 32 due to the too long distance between the mobile phone 31 and the smart watch 32 is avoided, and the power consumption of the smart watch 32 or the power consumption of the mobile phone 31 can be reduced.

In some embodiments, if the BT connection is not performed between the cell phone 31 and the smart watch 32 when the cell phone 31 is disconnected from the smart watch 32, the BT connection may be continuously maintained between the cell phone 31 and the smart watch 32 when the cell phone 31 is not in the first electronic fence, that is, the BT connection is continuously maintained between the cell phone 31 and the smart watch 32, and the BT connection is not performed between the cell phone 31 and the smart watch 32.

In other embodiments, if the cell phone 31 and the smart watch 32 perform a BT loopback when the cell phone 31 is disconnected from the smart watch 32, the smart watch 32 may control the cell phone 31 and the smart watch 32 not to perform the BT loopback when the cell phone 31 is not in the first electronic fence. For example, the smart watch 32 may stop BT loopback to the cell phone 31 and control the cell phone 31 to stop BT loopback to the smart watch 32.

The smart watch 32 may send a second instruction to the cloud server, where the second instruction is used to instruct the cell phone 31 to stop performing BT reconnection on the smart watch 32. The cloud server receives the second instruction from the smart watch 32 and forwards the second instruction to the cell phone 31. The handset 31 stops BT loopback with the smart watch 32.

Illustratively, the smart watch 32 may send the second instruction to the cloud server over a cellular network.

Illustratively, the cloud server may forward the second instruction to the handset 31 over the cellular network.

In some embodiments, the BT communication distance of electronic devices in an open area where there is generally less obstruction is greater than the BT communication distance of electronic devices in an area where there is more obstruction. That is, the BT communication distance is not a fixed value. The number of obstructions in the area of the electronic device may also affect the BT communication distance. Thus, in addition to the first electronic fence centered on the location of the smart watch 32, the smart watch 32 may also set up a second electronic fence. The center of the second electronic fence coincides with the center of the first electronic fence, and the area of the second electronic fence is larger than the area of the first electronic fence.

For example, as shown in fig. 3, the second electronic fence may also be a circular area centered at the location of the smart watch 32, and the radius of the second electronic fence is greater than the radius of the first electronic fence.

Secondly, the area size of the first electronic fence (or the distance from the center of the first electronic fence to the boundary of the first electronic device) set by the smart watch 32 can ensure that the two electronic devices in the first electronic fence are not affected by the shielding object basically, and the BT connection can be established. The area size of the second electronic fence (or the distance from the center of the first electronic fence to the boundary of the first electronic device) set by the smart watch 32 may ensure that the two electronic devices located in the second electronic fence are affected by the number of the shielding objects, and the BT connection may be established or may not be established. For example, the radius of the first electronic fence in fig. 3 may be equal to 50 meters (m), and the radius of the second electronic fence in fig. 3 may be equal to 100 m.

It should be noted that the second electronic fence may be a square or an oval in addition to the circular shape shown in fig. 3, and the shape of the second electronic fence is not limited in the embodiment of the present application.

Further, the smart watch 32 may determine whether the cell phone 31 is inside the second electronic fence when the cell phone 31 is not inside the first electronic fence. For example, the cell phone 31 shown in fig. 3 is not within the first electronic fence and is within the second electronic fence.

Specifically, as shown in fig. 5, S405 in the method may include S501, and when the method determines that the mobile phone 31 is not located in the first electronic fence after S404, S502-S503 may be executed.

S501, the smart watch 32 and the mobile phone 31 perform BT loopback according to the preset frequency 3.

When the mobile phone 31 is in the first electronic fence, the smart watch 32 and the mobile phone 31 may successfully establish a BT connection, and then the smart watch 32 and the mobile phone 31 perform a BT loopback according to the preset frequency 3.

The smart watch 32 may perform BT loopback on the cell phone 31 according to the preset frequency 3. The preset frequency 3 may be equal to the maximum frequency or a larger frequency of the BT loopback frequencies preset in the smart watch 32.

Alternatively, the cell phone 31 may BT-loop the smart watch 32 at the preset frequency 3. The preset frequency 3 may be equal to the maximum frequency or a larger frequency among BT backhaul frequencies preset in the handset 31.

It should be noted that, for a specific process of performing the BT reconnection between the smart watch 32 and the mobile phone 31 according to the preset frequency 3, reference may be made to the above description of performing the BT reconnection between the smart watch 32 and the mobile phone 31 in detail, which is not described herein again in this embodiment of the application.

S502, the smart watch 32 judges whether the mobile phone 31 is in the second electronic fence or not according to the position information of the mobile phone 31; the second electronic fence is centered on the location of the smart watch 32.

If the mobile phone 31 is not in the first electronic fence but in the second electronic fence, the smart watch 32 and the mobile phone 31 may perform BT loopback according to the preset frequency 4, that is, execute S503. If the mobile phone 31 is not located in the second electronic fence, the smart watch 32 and the mobile phone 31 may not perform BT loopback, i.e., execute S406. Wherein the preset frequency 4 is less than the preset frequency 3.

It should be noted that, in the specific process of determining whether the mobile phone 31 is located in the second electronic fence by the smart watch 32, reference may be made to the detailed description of determining whether the mobile phone 31 is located in the first electronic fence by the smart watch 32, which is not described herein again in this embodiment of the application.

S503, the smart watch 32 and the mobile phone 31 perform BT backhaul according to the preset frequency 4.

When the cell phone 31 is outside the first electronic fence and the cell phone 31 is inside the second electronic fence, the cell phone 31 and the smart watch 32 may successfully establish the BT connection, for example, when there are few obstructions in the second electronic fence, the two may successfully establish the BT connection. Thus, the smart watch 32 and the cell phone 31 can perform BT loop connection. However, the mobile phone 31 and the smart watch 32 may not be able to establish the BT connection, for example, when there are many obstacles in the second electronic fence, the two cannot establish the BT connection. Then, to reduce power consumption, the smart watch 32 and the handset 31 may BT-loop at a lower preset frequency 4.

Wherein, the preset frequency 3 is greater than the preview frequency 4.

In some embodiments, the smart watch 32 may BT-loop the cell phone 31 at the preset frequency 4. The preset frequency 4 may be equal to the minimum frequency or less of the BT backhaul frequencies preset in the smart watch 32.

Alternatively, the cell phone 31 may BT-loop the smart watch 32 at the preset frequency 4. The preset frequency 4 may be equal to the minimum frequency or a smaller frequency among BT backhaul frequencies preset in the handset 31.

It should be noted that, for the specific process of performing the BT reconnection between the smart watch 32 and the mobile phone 31 according to the preset frequency 4, reference may be made to the above description of performing the BT reconnection between the smart watch 32 and the mobile phone 31 in detail, and details of the embodiment of the present application are not described herein.

In other embodiments, the first electronic fence may be centered around the location of the cell phone 31, that is, the electronic device 3 may also be the electronic device 2 (that is, the electronic device 3 is the smart watch 32), in addition to the location of the smart watch 32. As shown in fig. 6, the first electronic fence set by the smart watch 32 may be a bounded area centered around the location of the cell phone 31. The position of the first electronic fence may vary with the position of the cell phone 31. Smart watch 32 may determine whether smart watch 32 is within the first electronic fence. If the smart watch 32 is located in the first electronic fence, which means that the distance between the cell phone 31 and the smart watch 32 is smaller than the distance between the center of the first electronic fence and the boundary of the first electronic device, for example, the distance between the cell phone 31 and the smart watch 32 is smaller than the BT communication distance, the smart watch 32 and the cell phone 31 may perform BT backhaul. Wherein the smart watch 32 shown in fig. 6 is not within the first electronic fence.

The BT reconnection method provided in the embodiment of the present application is described in detail below with reference to fig. 6. As shown in fig. 7, the method may not include S404, including S701.

S701, the smart watch 32 judges whether the smart watch 32 is in the first electronic fence or not according to the position information of the smart watch 32; the first electronic fence is centered on the position indicated by the position information of the cellular phone 31.

If the smart watch 32 is inside the first electronic fence, it means that the location of the cell phone 31 (i.e. the center of the first electronic fence) and the location of the smart watch 32 are both inside the first electronic fence, i.e. the distance between the cell phone 31 and the smart watch 32 does not exceed the distance from the center of the first electronic fence to the boundary of the first electronic device. Therefore, the smart watch 32 may set the distance from the center of the first electronic fence to the boundary of the first electronic device according to the BT communication distance so that the distance between the cell phone 31 and the smart watch 32 within the first electronic fence is smaller than or close to the BT communication distance.

Further, if the smart watch 32 is located in the first electronic fence, which means that the distance between the cell phone 31 and the smart watch 32 is the same as or close to the BT communication distance, the smart watch 32 and the cell phone 31 may perform BT loopback, i.e., execute S405. Thus, when the distance between the mobile phone 31 and the smart watch 32 is smaller than the BT communication distance, the BT connection between the smart watch 32 and the mobile phone 31 can be quickly realized through the BT backhaul.

Illustratively, as shown in fig. 6, the first electronic fence may be a circular area centered at the position of the cell phone 31 and having a radius of a preset length. The preset length may be equal to or close to the BT communication distance.

It should be noted that, the specific process of the smart watch 32 determining whether the smart watch 32 is located in the first electronic fence according to the location information of the smart watch 32 may refer to the detailed description that the smart watch 32 determines whether the mobile phone 31 is located in the first electronic fence according to the location information of the mobile phone 31, and details of this embodiment are not repeated herein.

In some embodiments, the smart watch 32 may set a second electronic fence in addition to the first electronic fence centered on the location of the cell phone 31. The center of the second electronic fence coincides with the center of the first electronic fence, and the area of the second electronic fence is larger than the area of the first electronic fence.

For example, as shown in fig. 6, the second electronic fence may be a circular area centered on the position of the mobile phone 31, and the radius of the second electronic fence is larger than that of the first electronic fence. The radius of the first electronic fence can be equal to 50m, and the radius of the second electronic fence can be equal to 100 m.

It should be noted that the first and second electronic fences centered on the position of the mobile phone 31 may be circular, square, or oval, as shown in fig. 6, and the shape of the first and second electronic fences is not limited in the embodiment of the present application.

Further, the smart watch 32 may determine whether the cell phone 31 is inside the second electronic fence when the smart watch 32 is not inside the first electronic fence. The smart watch 32 shown in fig. 6 is inside the second electronic fence.

Specifically, as shown in fig. 7, S405 in the method may include S702; the method may perform S703-S704 after S701 when it is determined that the smart watch 32 is not within the first electronic fence.

S702, the smart watch 32 and the mobile phone 31 perform BT backhaul according to the preset frequency 3.

It should be noted that, for a specific process of performing BT reconnection between the smart watch 32 and the mobile phone 31 according to the preset frequency 3, reference may be made to the above description of performing BT reconnection between the smart watch 32 and the mobile phone 31 in detail, and details of this embodiment of the present application are not described herein.

S703, the smart watch 32 judges whether the smart watch 32 is in the second electronic fence or not according to the position information of the smart watch 32; the second electronic fence is centered on the position indicated by the position information of the cellular phone 31.
