Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a device control method, apparatus, electronic device, and computer-readable storage medium. Background Technology

[0002] With the development of electronic devices, wearable devices such as headphones, smartwatches, smart bracelets, VR / AR glasses, and VR / AR helmets are becoming increasingly common, as are the application scenarios and internet access methods for these devices.

[0003] Since electronic devices often have service requirements such as data transmission, sharing, and access, they often need to establish communication links to access the network or to establish communication links with other electronic devices for data interconnection. Common ways to build communication links include Wireless Local Area Network (WLAN) (such as Wi-Fi networks), Bluetooth (BT), Bluetooth Low Energy (BLE), and Mobile Hotspot.

[0004] However, when electronic devices are used after establishing communication links, problems such as slow data communication rates and unstable communication often occur due to random switching of communication links across regions. Taking Bluetooth communication as an example, when multiple Bluetooth devices are connected to a mobile phone simultaneously, the phone sometimes randomly switches between these devices, causing sudden silences during calls because the Bluetooth signal is being switched away. Similarly, with Wi-Fi communication, when switching between multiple Wi-Fi base stations, such as in an office environment, the network sometimes suddenly switches to a Wi-Fi network with a weaker signal. This is because the current switching logic is based on RSSI strength, and the large error margin in RSSI data leads to random switching between multiple base stations.

[0005] Therefore, current electronic devices tend to randomly switch communication links when crossing regions, resulting in a technical problem where the wireless communication capabilities of electronic devices are not very stable when connecting across regions. Summary of the Invention

[0006] The main objective of this application is to provide a device control method, apparatus, electronic device, and computer-readable storage medium, which aims to solve the technical problem of low stability of wireless communication capabilities of electronic devices in cross-regional connections.

[0007] To achieve the above objectives, this application provides a device control method applied to an electronic device, the electronic device including a UWB module, the method comprising:

[0008] The target device is tracked and located using a UWB module to obtain its location information. The target device is an external device with which a communication link has been established.

[0009] Based on the location information of the target device, determine whether the target device is located within a preset geofence area, wherein the geofence area is the fence area corresponding to the location of the electronic device;

[0010] If so, the communication link established between the electronic device and the target device is taken as the preferred communication link, and the electronic device is controlled to perform data communication through the preferred communication link.

[0011] Optionally, after the step of determining whether the target device is located within a preset geofence area based on the location information of the target device, the method further includes:

[0012] If not, the signal request packet will be broadcast to all external devices;

[0013] Receive signal response packets returned by each of the external devices based on the signal request packet;

[0014] Based on the RSSI information in the signal response packets returned by each of the external devices, the signal strength of the alternative communication links between each of the external devices and the electronic device is determined;

[0015] The candidate communication link with the strongest signal strength is selected as the preferred communication link, and the step of controlling the electronic device to perform data communication through the preferred communication link is executed.

[0016] Optionally, prior to the step of establishing a communication link between the electronic device and the target device as a preferred communication link, the method further includes:

[0017] Based on the preset electronic fence mapping relationship, determine the range of candidate devices for the preset geofence area mapping;

[0018] Obtain the device identification information of the target device, and determine whether the target device belongs to the range of candidate devices based on the device identification information;

[0019] If it falls within the range of candidate devices, then the step of selecting the communication link established between the electronic device and the target device as the preferred communication link is performed.

[0020] Optionally, after the step of determining whether the target device belongs to the range of candidate devices, the method further includes:

[0021] If it is not within the range of candidate devices, then select one candidate device from the range of candidate devices as the new target device;

[0022] Execution: The step of establishing a communication link between the electronic device and the target device as the preferred communication link.

[0023] Optionally, the step of selecting a candidate device from the range of candidate devices as the new target device includes:

[0024] The location information of each candidate device is obtained by tracking and locating each candidate device within the candidate device range using the UWB module.

[0025] Based on the location information of each candidate device, determine the positional distance between the electronic device and each candidate device;

[0026] The candidate device with the smallest location distance is selected as the new target device.

[0027] Optionally, the step of selecting a candidate device from the range of candidate devices as the new target device includes:

[0028] The signal request packet is broadcast to each candidate device in the candidate device range;

[0029] Receive signal response packets returned by each of the candidate devices based on the signal request packet;

[0030] Based on the RSSI information in the signal response packets returned by each candidate device, the signal strength of the candidate communication link between each candidate device and the electronic device is determined;

[0031] The candidate device corresponding to the candidate communication link with the strongest signal strength is selected as the new target device.

[0032] Optionally, the method further includes:

[0033] The movement parameter information of the electronic device is detected in real time, including movement speed, movement acceleration and movement trajectory. Based on the movement parameter information of the electronic device, the target time for the electronic device to leave the current fenced area and enter a new fenced area is dynamically predicted.

[0034] At the target time, the new fenced area is set as the preset geofence area, and the process returns to execute the step of determining whether the target device is located within the preset geofence area based on the location information of the target device.

[0035] Furthermore, this application also provides a device control apparatus applied to an electronic device, the electronic device including a UWB module, the device control apparatus comprising:

[0036] The tracking and positioning module is used to track and locate the target device through the UWB module to obtain the location information of the target device, wherein the target device is an external device with which a communication link has been established with the electronic device;

[0037] The region identification module is used to determine whether the target device is located within a preset geofence area based on the location information of the target device, wherein the geofence area is the fence area corresponding to the location of the electronic device;

[0038] The link selection module is used to, if so, select the communication link established between the electronic device and the target device as the preferred communication link, and control the electronic device to perform data communication through the preferred communication link.

[0039] This application also provides an electronic device, which is a physical device, comprising: a memory, a processor, and a program of the device control method stored in the memory and executable on the processor. When the program of the device control method is executed by the processor, it can implement the steps of the device control method as described above.

[0040] This application also provides a computer-readable storage medium storing a program implementing a device control method, the program implementing the device control method being executed by a processor to implement the steps of the device control method as described above.

[0041] This application also provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the device control method described above.

[0042] The technical solution of this application uses a UWB module to track and locate a target device, obtaining the target device's location information. The target device is an external device with which a communication link has been established with the electronic device. Based on the target device's location information, it is determined whether the target device is located within a preset geofence area. This geofence area is the fenced area corresponding to the location of the electronic device. If so, the communication link established between the electronic device and the target device is selected as the preferred communication link, and the electronic device is controlled to communicate via this preferred link (since the target device is located within the preset geofence area, it indicates that the communication quality of the communication link between the electronic device and the target device is high). This avoids the technical problem of unstable wireless communication capabilities when the electronic device randomly switches communication links across regions. For example, taking Bluetooth communication as an example, when multiple Bluetooth devices are connected to a mobile phone simultaneously, the solution of this application will prevent the mobile phone from randomly switching between multiple Bluetooth devices, thus ensuring that the Bluetooth signal is not switched away during a call, preventing sudden silence. Taking Wi-Fi communication as an example, when switching between multiple Wi-Fi base stations, such as in an office environment, the solution proposed in this application will not encounter a sudden switch to a Wi-Fi network with a weak signal. This is because the switching logic of the technical solution proposed in this application is based on a user-defined virtual geofence. If the target device with an established communication link is within the geofence area, the communication link will not switch (provided it remains within the geofence area). This allows the solution to achieve positioning via UWB (Ultra Wide Band) ranging.

[0043] To construct a local area positioning network for the network system, realize automatic communication link selection and network switching, and ensure network stability when connecting across regions.

[0044] In other words, this application utilizes the high positioning accuracy of UWB to locate the position of the target device, enabling electronic devices with wireless communication capabilities to connect to the corresponding target device according to the user's requirements within a defined area, thereby avoiding the automatic and random switching of electronic devices to establish communication links with external devices.

[0045] To avoid inconvenience for users due to the presence of external devices, the UWB module in this application primarily implements distance measurement and positioning functions. Users can configure their ideal electronic boundaries (geofencing areas) through software.

[0046] This ensures that a designated electronic device has the first priority for signal connection within a specified electronic boundary, thereby avoiding random switching and solving the technical problem of low stability of wireless communication capabilities of electronic devices in cross-regional connections.

[0055] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0056] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Currently, when electronic devices are used after establishing communication links, they often experience slow data communication rates and unstable communication due to random switching of communication links across regions. Taking Bluetooth communication as an example, when multiple Bluetooth devices connect to a single phone simultaneously, the phone sometimes randomly switches between these devices, causing sudden silences during calls because the Bluetooth signal is being switched away. Similarly, with Wi-Fi communication, when switching between multiple Wi-Fi base stations, such as in an office environment, the network sometimes suddenly switches to a weaker Wi-Fi network. This is because the current switching logic is based on RSSI strength, which has a large error margin, leading to random switching between multiple base stations.

[0058] Therefore, current electronic devices tend to randomly switch communication links when crossing regions, resulting in a technical problem where the wireless communication capabilities of electronic devices are not very stable when connecting across regions.

[0059] Example 1

[0060] Based on this, please refer to Figure 1 This embodiment provides a device control method applied to an electronic device, the electronic device including a UWB module, the method comprising:

[0061] Step S10: Track and locate the target device using the UWB module to obtain the target device's location information;

[0062] The electronic devices used in the device control method of this embodiment can be wearable devices such as headphones, smartwatches, smart bracelets, VR / AR glasses, or VR / AR helmets.

[0063] In this embodiment, the target device is an external device that has established a communication link with the electronic device.

[0064] As those skilled in the art will recognize, UWB (Ultra Wideband) is a novel communication technology that differs significantly from traditional communication technologies. It does not require the carrier wave found in traditional communication systems; instead, it transmits data by sending and receiving extremely narrow pulses with durations of nanoseconds or less, thus achieving bandwidth on the order of GHz. UWB technology is a novel positioning and ranging technology. Due to its high carrier frequency, UWB achieves positioning accuracy up to the millimeter level, while maintaining angular accuracy within ±10°, making it highly suitable for integration with other functions to realize electronic boundary functions. Therefore, this embodiment can use a UWB (Ultra Wideband) module to track and locate a target device, obtaining its location information.

[0065] It should be noted that the methods for establishing a communication link between the target device and the electronic device include, but are not limited to, Wireless Local Area Network (WLAN) (such as Wi-Fi network), Bluetooth (BT), Bluetooth Low Energy (BLE), and Mobile Hotspot, etc. This embodiment does not make specific limitations on these methods.

[0066] Step S20: Determine whether the target device is located within a preset geofence area based on the location information of the target device;

[0067] The geofence area refers to the fenced area corresponding to the location of the electronic device.

[0068] In this embodiment, the geofence area is a fence area that the user has set in advance.

[0069] It should be noted that the geofence area can be a geofence area constructed based on the current location of the electronic device. That is, based on the current location of the electronic device, a preset coverage area near that current location constitutes a geofence area. This geofence area moves with the current location of the electronic device. For example, this geofence area is used to indicate the preset coverage area near the location of the electronic device. This preset coverage area can be customized by the user. The shape of the geofence for this customized preset coverage area can be, but is not limited to, a circle with a radius of 5km, an equilateral triangle with a distance of 6km from the center, etc. Of course, the geofence area can also be a geofence area constructed based on the actual geographical environment. This geofence area does not move with the current location of the electronic device. For example, this geofence area is used to indicate the boundary area of ​​a building, park, or community where the electronic device is located.

[0070] Step S30: If yes, then the communication link established between the electronic device and the target device is taken as the preferred communication link, and the electronic device is controlled to perform data communication through the preferred communication link.

[0071] In this embodiment, the preferred communication link refers to the communication link with the highest priority, and the electronic device and the target device preferably communicate data through the preferred communication link.

[0072] It is understandable that when the target device is located within a preset geofence area, it indicates that the communication quality of the communication link established between the electronic device and the target device is relatively high. Therefore, by using the communication link established between the electronic device and the target device as the preferred communication link, the electronic device is controlled to conduct data communication through this preferred communication link. This avoids the technical problem that the electronic device may randomly switch communication links when crossing regions, resulting in low stability of wireless communication capabilities in cross-regional connections.

[0073] The technical solution of this embodiment is to track and locate the target device using a UWB module to obtain the target device's location information. The target device is an external device with which a communication link has been established (5 channels) with the electronic device. Based on the target device's location information, it is determined whether the target device is in a certain position.

[0074] Within a preset geofence area, where the geofence area corresponds to the location of the electronic device, if so, the communication link established between the electronic device and the target device is selected as the preferred communication link, and the electronic device is controlled to perform data communication through the preferred communication link (since the target device is located within a geofence area).

[0075] When the device is within a pre-defined geofence area, it indicates that the communication quality of the communication link 0 established between the electronic device and the target device is relatively high, thus preventing the electronic device from randomly switching communication links when crossing areas.

[0076] This leads to technical issues with the stability of wireless communication capabilities in electronic devices across regions. For example, taking Bluetooth communication as an example, when multiple Bluetooth devices connect to a mobile phone simultaneously, the solution in this embodiment will prevent the mobile phone from randomly switching between multiple Bluetooth devices, thereby ensuring stable communication during calls.

[0077] In this case, the Bluetooth signal will not be switched away, and there will be no sudden silence. Taking Wi-Fi communication as an example, when switching between multiple Wi-Fi base stations, such as in an office environment, the solution in this embodiment will not encounter network interruptions.

[0078] However, it switches to a Wi-Fi network with a weaker signal because the switching logic of the technical solution in this embodiment is as follows:

[0079] Based on user-defined virtual geofences, if a target device with an established communication link is within the geofence area, the communication link will not switch (as long as it remains within the geofence area).

[0080] In the case of internal conditions, this embodiment uses UWB (Ultra Wide Band) ranging and positioning functions to construct a local positioning network for the network system, realize automatic communication link selection and network switching, and ensure network stability when connecting across regions.

[0081] In other words, this embodiment utilizes the high positioning accuracy of UWB to locate the position of the target device, enabling electronic devices with wireless communication capabilities to connect according to user requirements within a defined area.

[0082] By connecting to the corresponding target device, the electronic device is prevented from automatically and randomly switching to the external device (i.e., external device) with which it establishes a communication link, thus avoiding inconvenience to the user. The UWB module in this embodiment mainly implements...

[0083] The ranging and positioning functions allow users to configure their ideal electronic boundaries (geofence areas) through software, thereby ensuring that designated electronic devices have the first priority for signal connection within the designated electronic boundaries, thus avoiding random switching problems and solving the technical problem of low stability of wireless communication capabilities of electronic devices in cross-regional connections.

[0084] This embodiment utilizes the high-precision ranging and positioning capabilities of UWB, combined with a reasonable control strategy, to avoid the problem of random and frequent switching between multiple wireless devices, reducing the probability of user pain points and greatly improving the user experience. It should be noted that this embodiment is applicable to almost all consumer electronics products, as long as there is a wireless connection scenario, such as BT, BLE, and WIFI communication links.

[0085] In one implementable embodiment, after the step of determining whether the target device is located within a preset geofence area based on the location information of the target device, the method further includes:

[0086] Step A10: If not, broadcast the signal request packet to each external device;

[0087] Step A20: Receive signal response packets returned by each of the external devices based on the signal request packet;

[0088] Step A30: Determine the signal strength of the alternative communication links between each external device and the electronic device based on the RSSI information in the signal response packets returned by each external device.

[0089] Step A40: Select the candidate communication link with the strongest signal strength as the preferred communication link, and execute the step of controlling the electronic device to perform data communication through the preferred communication link.

[0090] In this embodiment, those skilled in the art will understand that both the signal request packet and the signal response packet are in the form of heartbeat packets.

[0091] It should be noted that since the signal response packet may contain RSSI (Received Signal Strength Indication) information, the signal strength value between each external device and the electronic device can be determined based on the RSSI information. Therefore, the candidate communication link with the strongest signal strength can be identified based on the RSSI information returned by each external device in its signal response packet.

[0092] In this embodiment, when it is determined that the target device is not located within the preset geofence area, the electronic device can detect the signal strength of each alternative communication link in real time or periodically, and determine in real time or periodically whether the currently constructed communication link is the communication link with the strongest signal strength that the electronic device can receive. If it is not the communication link with the strongest signal strength that the electronic device can receive, the currently constructed communication link is switched to the alternative communication link with the strongest signal strength.

[0093] This embodiment broadcasts a signal request packet to each external device when the target device is not located within a preset geofence area. It then receives signal response packets from each external device based on the signal request packet. According to the RSSI information in the signal response packets, it determines the signal strength of the alternative communication links between each external device and the electronic device. The alternative communication link with the strongest signal strength is selected as the priority communication link, and the following steps are executed: controlling the electronic device to communicate via the preferred communication link. This ensures that when the target device is not located within the preset geofence area, the signal strength of the existing communication link with the external device is the strongest, allowing for better allocation of signal resources to the electronic device and enabling it to obtain higher-quality signal resources. The electronic device selects the communication link with the best communication quality for data communication. This embodiment uses UWB (Ultra Wide Band) ranging and positioning to construct a local area positioning network for the network system, achieving automatic communication link selection and network switching, thus ensuring network stability during cross-regional connections.

[0094] In one possible implementation, please refer to Figure 2 Prior to the step of establishing the communication link between the electronic device and the target device as the preferred communication link, the method further includes:

[0095] Step S40: Determine the range of candidate devices for the preset geofence area mapping based on the preset electronic fence mapping relationship;

[0096] In this embodiment, the geofence mapping relationship can be pre-defined by the user. That is, at least one candidate device (i.e., the range of candidate devices) is set in the selected geofence area to prioritize the establishment of communication links.

[0097] Step S50: Obtain the device identification information of the target device, and determine whether the target device belongs to the range of candidate devices based on the device identification information;

[0098] As those skilled in the art will know, each external device has unique device identification information, which is used to characterize the device's identity. Therefore, this embodiment can determine the target device's identity information by obtaining the target device's device identification information, thereby facilitating the identification of whether the target device belongs to the range of candidate devices based on the target device's identity information.

[0099] Step S60: If it falls within the range of candidate devices, then execute the step of selecting the communication link established between the electronic device and the target device as the preferred communication link.

[0100] For example, after the step of determining whether the target device belongs to the range of candidate devices, the method further includes:

[0101] Step B10: If the device is not within the range of candidate devices, then select a candidate device from the range of candidate devices as the new target device.

[0102] Step B20: Perform the step of selecting the communication link established between the electronic device and the target device as the preferred communication link.

[0103] In this embodiment, if the target device is not within the range of candidate devices, it means that the target device is not among the candidate devices for which a communication link is preferentially established with the electronic device. Therefore, this embodiment selects a candidate device from the range of candidate devices as a new target device when it is determined that the target device is not within the range of candidate devices, and performs the step of selecting the communication link established between the electronic device and the target device as the preferred communication link. This allows for better allocation of signal resources to the electronic device, enabling it to obtain higher quality signal resources. The electronic device is determined to conduct data communication by selecting the communication link with the best communication quality. After switching to establish a communication link with the candidate device, it does not switch again (while remaining within the geofence area). This allows this embodiment to construct a local positioning network of the network system through UWB (Ultra-Wide Band) ranging and positioning function, realizing automatic communication link selection and network switching, thus ensuring network stability during cross-regional connections.

[0104] In one possible implementation, the step of selecting a candidate device from the range of candidate devices as the new target device includes:

[0105] Step C10: Track and locate each candidate device in the candidate device range using the UWB module to obtain the location information of each candidate device;

[0106] Step C20: Determine the positional distance between the electronic device and each of the candidate devices based on the position information of each candidate device;

[0107] Step C30: Select the candidate device with the smallest location distance as the new target device.

[0108] In this embodiment, those skilled in the art will know that the smaller the distance between the electronic device and the candidate device, the better the communication quality of the communication link between the electronic device and the candidate device tends to be.

[0109] Therefore, this embodiment uses a UWB module to track and locate each candidate device within the candidate device range, obtaining the location information of each candidate device. Based on the location information of each candidate device, the distance between the electronic device and each candidate device is determined. The candidate device with the smallest distance is selected as the new target device, which facilitates the subsequent construction of a communication link between the electronic device and the new target device. This link is then used as the preferred communication link for data communication, thereby enabling better allocation of signal resources for the electronic device and allowing it to obtain higher quality signal resources. The electronic device selects the communication link with the best communication quality for data communication, and once the preferred communication link is selected, it does not switch (while remaining within the geofence area). This further improves the stability of the electronic device's wireless communication capability in cross-regional connections.

[0110] In another possible implementation, the step of selecting a candidate device from the range of candidate devices as the new target device includes:

[0111] Step D10: Broadcast the signal request packet to each candidate device in the candidate device range;

[0112] Step D20: Receive signal response packets returned by each of the candidate devices based on the signal request packet;

[0113] Step D30: Determine the signal strength of the candidate communication link between each candidate device and the electronic device based on the RSSI information in the signal response packet returned by each candidate device.

[0114] Step D40: Select the candidate device corresponding to the candidate communication link with the strongest signal strength as the new target device.

[0115] This embodiment broadcasts a signal request packet to each candidate device within the candidate device range, receives signal response packets from each candidate device based on the signal request packet, and determines the signal strength of the candidate communication link between each candidate device and the electronic device based on the RSSI information in the signal response packets returned by each candidate device. Then, the candidate device corresponding to the candidate communication link with the strongest signal strength is selected as the new target device. This facilitates the subsequent construction of a communication link between the electronic device and the new target device, and uses it as the preferred communication link for data communication. This allows for better allocation of signal resources to the electronic device, enabling it to obtain higher-quality signal resources. The electronic device selects the communication link with the best communication quality for data communication, and once the preferred communication link is selected, it does not switch back (while remaining within the geofence area). This further improves the stability of the electronic device's wireless communication capability in cross-regional connections.

[0116] To aid in understanding the technical concept of this application, a specific embodiment is provided; please refer to [reference needed]. Figure 3 , Figure 3 Here is a flowchart of a device control strategy according to a specific embodiment of this application:

[0117] In this specific embodiment, the electronic device includes a System-on-Chip (SOC) module and a UWB module. The user can actively set the electronic boundary range (i.e., a preset geofence area) by inputting information on the electronic device's human-machine interface. The SOC module receives this actively set electronic boundary range, and then the UWB module tracks and locates the target peripheral with the established communication link (including determining the orientation and distance of the external device) to determine whether the target peripheral is within the electronic boundary range. If the target peripheral is within the electronic boundary range, it is determined to have the highest priority, and switching peripherals is prohibited. If the target peripheral is not within the electronic boundary range, the switching logic for establishing the communication link is performed by detecting the RSSI signals of each peripheral and selecting the peripheral with the strongest RSSI signal. The scenarios for establishing communication links with peripherals include, but are not limited to, BT, BLE, and WIFI communication link scenarios.

[0118] It should be noted that the many details described in this specific embodiment are only helpful for understanding the technical concept of this application and do not constitute a limitation of this application. Any simple modifications based on the technical concept of this application should be within the protection scope of this application.

[0119] Example 2

[0120] Based on the first embodiment of this application, in another embodiment of this application, the same or similar content as in Embodiment 1 above can be referred to the above description and will not be repeated hereafter. In addition, the method further includes:

[0121] Step E10: Real-time detection of the movement parameter information of the electronic device, wherein the movement parameter information includes movement speed, movement acceleration and movement trajectory; based on the movement parameter information of the electronic device, dynamically predict the target time when the electronic device leaves the current fence area and enters a new fence area.

[0122] In this embodiment, as those skilled in the art will know, the moving speed of the electronic device can be detected by a speed sensor integrated in the electronic device, the moving acceleration of the electronic device can be detected by an accelerometer integrated in the electronic device, and the moving trajectory of the electronic device can be detected by an IMU (Inertial Measurement Unit) sensor integrated in the electronic device. Alternatively, environmental image information can be dynamically acquired by a camera integrated in the electronic device, and the moving trajectory of the electronic device can be identified based on the dynamically acquired environmental image information.

[0123] Step E20: At the target time, the new fenced area is set as the preset geofence area, and the process returns to execute the step of determining whether the target device is located within the preset geofence area based on the location information of the target device.

[0124] In this embodiment, it should be noted that as the electronic device enters different geofence areas, the preset geofence area also needs to be updated accordingly.

[0125] Therefore, this embodiment detects the movement parameter information of the electronic device in real time, including movement speed, movement acceleration, and movement trajectory. Based on the movement parameter information of the electronic device, it dynamically predicts the target time when the electronic device leaves the current geofence area and enters a new geofence area. At the target time, the new geofence area is set as the preset geofence area, and the process returns to execute the step of determining whether the target device is located within the preset geofence area based on the target device's location information. This ensures in real time that the communication link established between the electronic device and the external device is the preferred communication link with the highest communication quality, and controls the electronic device to conduct data communication through this communication link. This allows for better allocation of signal resources to the electronic device, enabling it to obtain higher-quality signal resources.
