Abstract

A positioning method and a related device, which are used for realizing low-power-consumption positioning and improving the endurance capability. For example, a first device determines whether a first condition is satisfied, wherein the first condition comprises at least one of the following: a current electric quantity being less than a first preset electric quantity, a current load being greater than a first preset load, a current time being within a first preset time period, and a positioning system in the first device detecting that the first device enters a first geofence; and if it is determined that the first device satisfies the first condition, the positioning mode of the first device is switched from a first mode to a second mode, wherein the first mode involves performing positioning by means of the positioning system, and the second mode involves performing positioning by means of a short-distance communication module in the first device. Since the power consumption of positioning in a second mode is relatively low, the power-down speed of a first device can be reduced, thereby improving the endurance capability of the first device.

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on January 31, 2024, with application number 202410144744.4 and application name "A positioning method and related equipment", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of terminal technology, and in particular to a positioning method and related equipment. Background Art

[0004] Children, the elderly, and other vulnerable groups are more susceptible to safety accidents due to their limited safety awareness and self-protection abilities. For example, children and the elderly frequently get lost while out and about. Therefore, the safety of vulnerable groups like children and the elderly is a matter of great concern to society today.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a positioning method and related devices to achieve low-power positioning and improve battery life.

[0007] In a first aspect, a positioning method is provided, which is applicable to a first device. The first device may be, for example, a watch, such as a children's watch. The first device includes a short-range communication module. The method includes: determining whether the first device meets a first condition, the first condition including at least one of the following: the current power is less than a first preset power, the current load is greater than a first preset load, the current time is in a first preset time period, and the first device is detected to enter a first geographic fence through the positioning system in the first device; if it is determined that the first device meets the first condition, the positioning mode of the first device is switched from the first mode to the second mode, the first mode is positioning through the positioning system, and the second mode is positioning through the short-range communication module.

[0008] In an embodiment of the present application, taking the first device as a children's watch as an example, the children's watch includes two positioning modes, a first mode and a second mode. The first mode is positioned by a positioning system (for example, GPS or GNSS). The second mode is positioned by a short-range communication module. When the first condition is met, the children's watch switches from the first mode to the second mode. The power consumption consumed by the second mode is lower, which can reduce the power-off speed of the children's watch and improve the battery life.

[0009] In one possible design, the positioning through the short-range communication module includes: sending a positioning request to surrounding devices through the short-range communication module, the positioning request is used to trigger the surrounding devices to report their geographic locations to the cloud, and the positioning request includes the device identification of the first device.

[0010] In the embodiment of the present application, the children's watch can trigger surrounding devices to report their geographic location to the cloud through the short-range communication module. Therefore, the children's watch does not need to be located by a local positioning system (such as GPS) or communicate with the cloud over long distances, which reduces power consumption and improves battery life.

[0011] In one possible design, the positioning through the short-range communication module includes: sending a positioning request to the surrounding devices through the short-range communication module, the positioning request is used to trigger the surrounding devices to send the geographic location to the first device; and sending the second geographic location to the cloud based on the first geographic location sent by the surrounding devices.

[0012] In the embodiment of the present application, the children's watch can obtain the geographic location from surrounding devices through the short-range communication module. Therefore, the children's watch does not need to use the local positioning system (such as GPS) to determine the geographic location, which reduces power consumption and improves battery life.

[0013] In one possible design, the first geographical location is the same as the second geographical location and is the geographical location of the first device; the first geographical location is the geographical location of the surrounding devices, and the second geographical location is the geographical location of the first device calculated based on the first geographical location.

[0014] In an embodiment of the present application, the children's watch can obtain a first geographic location from surrounding devices through a short-range communication module, and then send a second geographic location to the cloud. In one case, the first geographic location is the same as the second geographic location, and serves as the geographic location of the first device. In another case, the first geographic location is the geographic location of the surrounding devices (for example, the geographic location detected by the GPS of the surrounding devices), and the second geographic location is the geographic location of the first device calculated based on the first geographic location. In this way, on the one hand, the children's watch side does not need to use the local positioning system (such as GPS) to determine the geographic location, the power consumption is low, and the obtained geographic location is the calculated geographic location of the first device, which is more accurate.

[0015] In one possible design, after the positioning system detects that the first device enters a first geo-fence, the method further includes: turning off the positioning system.

[0016] In an embodiment of the present application, after the children's watch detects entry into the first geo-fence through a positioning system (e.g., GPS or GNSS), it can switch to the second mode. At this time, the children's watch can turn off the positioning system to avoid wasting power.

[0017] In one possible design, the method further includes: when determining that the first device satisfies a second condition, switching the positioning mode from the second mode to the first mode, where the second condition includes at least one of the following:

[0018] The current power level is greater than or equal to the first preset power level; or,

[0019] The current load is less than or equal to the first preset load; or,

[0020] The current time is not within the first preset time period; or,

[0021] It is determined through the second mode that the first device moves out of the first geo-fence.

[0022] In an embodiment of the present application, when the second condition is met, the children's watch switches from the second mode to the first mode. Since the first mode is positioned by a positioning system, it is more accurate and improves positioning accuracy.

[0023] In one possible design, the method further includes: when determining that the first device satisfies a third condition, starting a positioning function, where the third condition includes at least one of the following:

[0024] The monitoring device fails to contact the first device for a first preset period of time; or

[0025] The device is not used for more than a second preset time period; or

[0026] The current time is within the second preset time period.

[0027] Optionally, the monitoring device of the first device can be understood as the device of the guardian of the user corresponding to the first device. Taking the user corresponding to the first device as an example, if the user is a child and the guardian is a parent, the monitoring device of the first device is the parent's mobile phone.

[0028] In an embodiment of the present application, the positioning function in the children's watch does not need to be turned on all the time. When the third condition is met, the positioning function can be automatically started to avoid wasting power due to the positioning function being turned on for a long time.

[0029] In one possible design, the method further includes: receiving reminder information sent by the surrounding devices through the short-range communication module, where the reminder information comes from the cloud or the monitoring device of the first device.

[0030] In an embodiment of the present application, the children's watch can receive reminder messages sent by parents through surrounding devices to prevent children from getting lost as much as possible.

[0031] In one possible design, before sending a positioning request to the surrounding devices through the short-range communication module, the method also includes: when it is determined that there are multiple surrounding devices, determining a target device among the multiple surrounding devices based on the device distance and / or device type of the surrounding devices; sending a positioning request to the surrounding devices through the short-range communication module includes: sending a positioning request to the target device through the short-range communication module.

[0032] In the embodiment of the present application, the children's watch can identify a target device among multiple surrounding devices and then assist in positioning through the target device. In this way, the children's watch can select surrounding devices with higher security as much as possible, such as surrounding smart bus stops, road test units, etc., to improve safety.

[0033] In one possible design, before sending a positioning request to surrounding devices through the short-range communication module, the method also includes: when it is determined that there are no surrounding devices, outputting prompt information, and the prompt information is used to prompt the first device to move to a new location.

[0034] In an embodiment of the present application, when the children's watch determines that there are no surrounding devices, it can prompt the user to move to a new location in order to find surrounding devices as much as possible to assist the children's watch in positioning and ensure the safety of the child.

[0035] In one possible design, the positioning system includes: a global positioning system GPS, or a global navigation satellite system GNSS; the short-range communication module includes: Bluetooth, low-power Bluetooth BLE, near-field communication NFC, or ultra-wideband UWB.

[0036] It should be noted that this article uses the positioning system including GPS or GNSS as an example, of course, other positioning methods can also be included. In addition, this article uses the short-range communication module including Bluetooth, BLE, NFC, and UWB as an example, of course, other short-range communication methods can also be included, and the embodiments of this application are not limited thereto.

[0037] In a possible design, before sending a positioning request to surrounding devices through the short-range communication module, it also includes: shutting down the first device or entering flight mode.

[0038] In an embodiment of the present application, positioning can also be performed when the children's watch is in an offline state, so as to avoid the inability to find the location of the children's watch when it is offline.

[0039] In a second aspect, a positioning method is also provided, applicable to a second device, where the second device is a monitoring device for a first device. For example, the first device is a children's watch, and the second device is a parent's mobile phone. The method includes: receiving the geographic location of the first device from the cloud; displaying the geographic location of the first device; displaying a first shortcut, where the first shortcut is used to contact the first device via surrounding devices of the first device; receiving an operation on the first shortcut; and sending a first message to the cloud, where the first message is used to trigger the cloud to send a reminder message to the first device via the surrounding devices.

[0040] In an embodiment of the present application, the parent's mobile phone can contact the child's watch through the peripheral devices of the child's watch to ensure that the child's watch can be contacted as much as possible to ensure the safety of the child.

[0041] In one possible design, the method further includes: displaying N shortcuts, where the N shortcuts include at least one of the following:

[0042] a second shortcut to contacting said first device by phone, or,

[0043] a third shortcut to contacting the first device via SMS, or,

[0044] a fourth shortcut to contact the first device via a voice call, or,

[0045] A fifth shortcut for contacting the first device via a video call.

[0046] In an embodiment of the present application, one or more shortcuts can be displayed on the parent's mobile phone, so the parent can quickly contact the child's watch with high efficiency.

[0047] In one possible design, the number and / or display status of the N shortcuts changes with the current status of the first device.

[0048] In one possible design, the current state of the first device includes the current power level of the first device.

[0049] For example, when the current battery level of the watch is greater than or equal to a preset value (for example, 20%), all N shortcuts are displayed. When the current battery level of the watch is less than a preset value (for example, 20%), only some shortcuts may be displayed, for example, only shortcuts corresponding to contact methods with lower power consumption are displayed, and shortcuts corresponding to contact methods with higher power consumption are not displayed, for example, the fifth shortcut corresponding to video calls is not displayed. Alternatively, when the current battery level of the watch is less than a preset value (for example, 20%), all N shortcuts may be displayed, but the display status of some of the shortcuts is grayscale (i.e., grayed out), for example, the fifth shortcut corresponding to video calls is grayed out. This can prevent parents from accidentally touching the fifth shortcut to initiate a video call to the child's watch, causing the child's watch to lose power quickly.

[0050] In a third aspect, a positioning method is also provided, applicable to a third device, wherein the third device includes a short-range communication module. The method comprises: receiving, via the short-range communication module, a positioning request sent by a first device, where the first device is a surrounding device of the third device, the positioning request being used to trigger the third device to report its geographic location to the cloud; sending the geographic location to the cloud; receiving a first message sent by the cloud, where the first message is used to trigger the third device to send a reminder message to the first device; and sending the reminder message to the first device.

[0051] In the embodiment of the present application, the third device can assist in locating the surrounding first device, and can also help contact the first device to ensure the safety of the user of the first device (for example, a child).

[0052] In one possible design, the geographic location sent to the cloud is the geographic location of the third device, or the geographic location of the first device calculated based on the geographic location of the third device.

[0053] In an embodiment of the present application, the third device can calculate the geographic location of the first device and then send the geographic location to the cloud, thereby improving the positioning accuracy of the first device without consuming the power consumption of the first device.

[0054] In one possible design, before sending the geographic location to the cloud, the method further includes: outputting a prompt message, wherein the prompt message is used to prompt whether to agree to assisted positioning; and receiving a consent instruction.

[0055] In an embodiment of the present application, the third device can assist the first device in positioning after obtaining the user's consent, which provides a better user experience.

[0056] In a fourth aspect, a positioning method is also provided, which is applicable to the cloud, and the method includes: receiving the geographic location of a first device from a third device; sending the geographic location to a monitoring device of the first device; receiving a first message sent by the monitoring device, and the first message is used to trigger the cloud to send a reminder message to the first device through the third device; based on the first message, sending a second message to the third device, and the second message is used to trigger the third device to send the reminder message to the first device.

[0057] In an embodiment of the present application, the cloud can send a reminder message to the first device through a third device to contact the first device in a timely manner.

[0058] In one possible design, the method further includes: sending a prompt message to the monitoring device of the first device, prompting the user to check the geographic location.

[0059] In an embodiment of the present application, after receiving the geographic location of the first device from the third device, the cloud can prompt the monitoring device of the first device to check the geographic location to ensure that the guardian can grasp the geographic location of the first device as soon as possible.

[0060] In one possible design, there are multiple third devices and multiple geographic locations of the first device. Before sending the geographic location to the monitoring device of the first device, the method also includes: determining a geographic location based on the multiple geographic locations; sending the geographic location to the monitoring device of the first device includes: sending the determined geographic location to the monitoring device of the first device.

[0085] Below, some terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0086] The at least one involved in the embodiments of the present application includes one or more; wherein, more means greater than or equal to two. In addition, it should be understood that, in the description of this specification, words such as "first", "second", and "third" are only used for the purpose of distinguishing the description, and cannot be understood as expressing or implying relative importance, nor can they be understood as expressing or implying order. For example, the first device and the second device do not represent the importance of the two or the order of the two, but are only for distinguishing the description. In the embodiments of the present application, "and / or" is only a description of the association relationship, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship.

[0087] The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only references to the directions in the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0088] References to "one embodiment," "in some examples," or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the specification. Thus, phrases such as "in some examples," "in one embodiment," "in some other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0089] The following describes the positioning method provided by the embodiments of the present application in conjunction with the accompanying drawings.

[0090] As mentioned above, vulnerable groups such as children and the elderly are prone to getting lost. To this end, an embodiment of the present application provides a positioning method. Taking children as an example, children can wear wearable devices. The wearable devices have a positioning function and can locate the current geographic location. The parent's mobile phone can obtain the current geographic location of the wearable device. Therefore, the parent can check the child's geographic location on the mobile phone and quickly find the child based on the geographic location. The technical solution of the embodiment of the present application can prevent children from getting lost as much as possible and improve safety.

[0091] The present application embodiment provides two positioning solutions, which are described below. For ease of description, the following description takes the wearable device as a watch as an example.

[0092] The first positioning solution

[0093] In this solution, the watch worn by the child includes a Global Positioning System (GPS) to locate the current geographic location. After the watch obtains the current geographic location through GPS, it can send the current geographic location to the parent's mobile phone. Considering that the child may be far away from the parent, for example, the parent is at work and the child is at school. Therefore, the communication between the child's watch and the parent's mobile phone can be long-distance communication. One feasible way of long-distance communication is through cloud communication.

[0094] For example, please refer to Figure 1, which is a schematic diagram of a communication system provided in an embodiment of the present application. In Figure 1, the child's watch communicates with the parent's mobile phone through the cloud. For example, the watch includes a long-distance communication module for communicating with the cloud. Of course, although not shown in Figure 1, the parent's mobile phone also includes a long-distance communication module for communicating with the cloud. Exemplarily, the long-distance communication module can be a wifi module or a mobile communication module. The wifi module is used to access wifi. The mobile communication module is used to access a mobile data network, and the mobile data network can be, for example, 3G, 4G, 5G, 6G, etc.

[0095] Therefore, the positioning process of the communication system shown in Figure 1 may include: after the GPS in the watch locates the current geographical location, the watch sends the current geographical location to the cloud through the long-distance communication module. The cloud sends the current geographical location of the watch to the parent's mobile phone. It is understandable that before sending the current geographical location of the watch to the parent's mobile phone, the cloud can also first determine which device to send the current geographical location of the watch to, and after determining to send it to the mobile phone, send the geographical location to the mobile phone. One possible implementation method is to record the association relationship between the child's watch and the parent's mobile phone in the cloud, and the cloud determines that the current geographical location of the watch needs to be sent to the parent's mobile phone based on the association relationship. Among them, there are many ways for the cloud to obtain the association relationship between the watch and the mobile phone, for example, including but not limited to the following method 1 or method 2.

[0096] In method 1, the child's watch and the parent's phone are registered in the cloud using the same account (for example, a Huawei account). Therefore, the cloud records the devices corresponding to the account as the watch and the phone. This allows the cloud to understand the relationship between the child's watch and the parent's phone. For example, each time the watch reports its location to the cloud, it can also report the currently logged-in account. If the cloud determines that the account is associated with another device, namely a phone, it sends the watch's location to that phone.

[0097] Method 2: The child's watch is registered in the cloud using account A, and the parent's phone is registered in the cloud using account B. Account A and account B are different. Optionally, the phone can obtain the watch's account A and then send a binding request to the cloud, which includes account A and account B. After receiving the binding request, the cloud records the association between account A and account B. There are various ways for the phone to obtain the watch's account A. For example, it can scan a QR code on the watch to obtain account A, or manually enter account A, etc. While the example above uses the phone obtaining the watch's account A and then sending a binding request to the cloud, it is understandable that the watch can also obtain the phone's account B and then send a binding request to the cloud, which includes account A and account B. The principle is the same as above and will not be repeated here. Therefore, each time the watch reports its geographic location to the cloud, it can also report the currently logged-in account A. Based on the association between account A and account B, the cloud determines to send the watch's geographic location to the device corresponding to account B, namely the phone.

[0098] It should be noted that FIG1 takes the children's watch including GPS as an example. Optionally, in addition to GPS, other positioning methods may also be used, such as Global Navigation Satellite System (GNSS) positioning. This embodiment of the present application does not limit this.

[0099] Therefore, through the above positioning solution, parents can check the current geographic location of their children through their mobile phones, so as to quickly find their children and improve safety. Moreover, since the watch uses GPS positioning, the positioning is more accurate, so it is safer.

[0100] The second positioning solution

[0101] Considering that GPS positioning consumes more power and reduces battery life, this solution uses other devices to assist with positioning rather than GPS. This eliminates GPS positioning, reducing power consumption and improving battery life.

[0102] In this solution, the watch needs to be positioned with the help of other devices. If the other devices are far away from the watch, accurate positioning cannot be guaranteed. Therefore, in this solution, it is considered to use devices near the watch to assist in positioning to improve positioning accuracy. Therefore, the watch may include a short-range communication function for communicating with nearby devices (abbreviated as: surrounding devices). For example, please refer to Figure 2A, which is another schematic diagram of a communication system provided in an embodiment of the present application. Unlike Figure 1, the watch in Figure 2A includes a short-range communication module for realizing short-range communication. Optionally, the short-range communication module can be based on Bluetooth technology, Bluetooth Low Energy (BLE) technology, near field communication (NFC) technology, ultra-wideband (UWB) technology, etc., which is not limited in the embodiment of the present application. Therefore, in Figure 2A, the watch can establish communication with surrounding devices through the short-range communication module to assist in positioning through surrounding devices.

[0103] Optionally, the surrounding devices can be any type of device. In some examples, the surrounding devices can be mobile devices, such as wearable devices such as watches or bracelets, mobile phones, tablet computers, laptops, etc., and vehicle-mounted devices, etc. An exemplary scenario is that a child is carrying a watch on a street, and the watch is assisted in positioning by the mobile devices of passers-by around. In other examples, the surrounding devices can also be non-mobile devices. Non-mobile devices can be understood as devices with relatively fixed positions. For example, smart signs, smart bus stops, road test units (RSU), smart utility poles, etc. set on the road. In short, the embodiments of the present application do not limit the specific types of surrounding devices.

[0104] In an embodiment of the present application, the watch is assisted in positioning by surrounding devices, including but not limited to the following two solutions.

[0105] Solution 1: The watch sends a positioning request to a nearby device via the short-range communication module. After receiving the positioning request, the nearby device sends its geographic location to the watch, which can be in at least one of the following two situations.

[0106] In case 1, the geographic location includes the current geographic location of the surrounding devices. For example, the current geographic location of the surrounding devices detected by their local GPS. In other words, the watch obtains a geographic location not obtained by the watch's internal GPS, but rather by utilizing the GPS of the surrounding devices. Since the watch does not use GPS positioning, power consumption is low. In this case, after receiving the geographic location of the surrounding devices, the watch can report this geographic location to the cloud. Alternatively, after receiving the geographic location of the surrounding devices, the watch can calculate the current geographic location of the watch based on the geographic locations of the surrounding devices and then report the calculated current geographic location of the watch to the cloud. For example, the watch can calculate the current geographic location of the watch based on the geographic locations of the surrounding devices and the positional relationship between the surrounding devices and the watch. Optionally, the relative positional relationship between the watch and the surrounding devices may include the direction and / or distance of the watch with respect to the surrounding devices as the center. For example, if the watch is located 3 meters to the left of the center of the surrounding devices, the surrounding devices will determine that the current geographic location of the watch is 3 meters to the left of the watch's current geographic location. Optionally, the relative positional relationship between the watch and the surrounding devices can be obtained using Bluetooth AOA positioning technology or other technologies, which are not described in detail in this embodiment of the application.

[0107] In case 2, the location includes the watch's current location calculated by surrounding devices based on the watch's current location. The calculation process for the watch's current location is described above and will not be repeated here. In this case, the location received from the surrounding devices is the calculated location, so the watch does not need to calculate it itself, reducing power consumption.

[0108] In the second solution, the watch sends a positioning request to surrounding devices via the short-range communication module. After receiving the positioning request, the surrounding devices report their geographic location to the cloud. This geographic location can include the current geographic location of the surrounding devices (i.e., scenario 1 above) and / or the current geographic location of the watch calculated by the surrounding devices based on their current geographic location (i.e., scenario 2 above).

[0109] It should be noted that the above-mentioned solutions 1 and 2 can be used separately or in combination. Taking the combination of solution 1 and solution 2 as an example, the watch sends a positioning request to the surrounding devices through the short-range communication module. After receiving the positioning request, the surrounding devices send their geographic location to the watch and the cloud respectively. The geographic location can include at least one of the above-mentioned scenarios 1 and 2.

[0110] The following mainly uses Solution 2 as an example for explanation. Please refer to Figure 2B, which is a flow chart of the positioning method provided in one embodiment of the present application. This method can be applied to the communication system shown in Figure 2A. As shown in Figure 2B, the process includes:

[0111] S201: The short-range communication module in the children's watch sends a positioning request to surrounding devices. Correspondingly, the surrounding devices receive the positioning request.

[0112] In some examples, the positioning request may include a watch identifier, which may include the watch's device identifier (e.g., device model), and / or a currently logged-in account, such as a system account. For example, if the watch is a Huawei watch, the system account may be a Huawei account.

[0113] S202: The surrounding devices determine their geographic locations.

[0114] In some embodiments, before S202, the process may further include: the surrounding devices start an auxiliary positioning function. The auxiliary positioning function can be understood as a function that helps other devices locate. Optionally, the auxiliary positioning function in the surrounding devices can be automatically started or manually started.

[0115] Take automatic activation as an example. For example, upon receiving a positioning request, surrounding devices can automatically activate the assisted positioning function. Optionally, when surrounding devices determine that conditions are met, they can disable the assisted positioning function to save power. These conditions may include, for example, the completion of reporting the geographic location and / or the activation time of the assisted positioning function reaching a preset duration.

[0116] Take manual activation as an example, and take the surrounding device as a mobile phone as an example. For example, referring to (a) in FIG3 , the mobile phone displays an interface, which may be the interface of the setting application in the mobile phone. The interface includes a switch 300 for the auxiliary positioning function. When the mobile phone receives an operation for the switch 300, the auxiliary positioning function is activated. It should be noted that in (a) in FIG3 , the switch 300 is taken as an example in which the switch 300 is located in the setting application. Optionally, the switch 300 can also be located in other positions in the mobile phone, and this embodiment of the application is not limited thereto.

[0117] In some embodiments, before S202, it may also include: the surrounding device outputs a prompt message, the prompt message is used to prompt whether to agree to assisted positioning. After the surrounding device receives the consent instruction, S202 can be executed. For example, refer to (b) in Figure 3. Taking the surrounding device as a mobile phone as an example, a prompt message is displayed on the mobile phone: A device requests your assisted positioning, do you agree? The mobile phone may also display an agree button and a reject button. When the mobile phone receives an operation for the agree button, S202 can be executed. In (b) in Figure 3, it is worth noting that since the positioning request received by the surrounding device includes the watch logo, in order to protect the safety of children, the watch logo may not be displayed in the prompt message displayed by the surrounding device. Optionally, in (b) in Figure 3, when the mobile phone receives an operation for the agree button, if it detects that the assisted positioning function has not been turned on for the mobile phone, the assisted positioning function can be automatically started or the interface of (a) in Figure 3 can be displayed, and the assisted positioning function can be manually started by the user.

[0118] Optionally, the geographic location determined by the surrounding device in S202 may include: the current geographic location of the surrounding device, and / or the current geographic location of the watch calculated by the surrounding device based on the current geographic location of the surrounding device. The calculation process of the current geographic location of the watch is described above and will not be repeated here. The current geographic location of the surrounding device may be the current geographic location detected by the GPS in the surrounding device.

[0119] S203: The surrounding device sends first information to the cloud, where the first information includes a geographic location and first indication information. The first indication information is used to indicate that the geographic location is the geographic location of the watch.

[0120] Optionally, the first indication information can be used to indicate the identification of the watch. For details about the identification of the watch, please refer to the above description. It should be noted that, in S203, the geographic location and the first indication information are sent in the same message (or message) as an example. Optionally, the geographic location and the first indication information can also be sent in different messages (or messages), that is, they are sent independently.

[0121] In some examples, to protect the privacy of surrounding devices, surrounding devices may not send local information to the cloud, such as device identification, system account, phone number, etc. In other words, the cloud receives the geographic location sent by the anonymous device, and this geographic location is the geographic location of the watch. Of course, surrounding devices can also send local information to the cloud, and this embodiment of the application is not limited to this.

[0122] S204, the cloud sends the geographic location to the parent's mobile phone.

[0123] It is understandable that the cloud records the association between the child's watch and the parent's mobile phone, and through this association, it is determined that the watch's geographic location needs to be sent to the parent's mobile phone. For the process of obtaining the association in the cloud, please refer to the previous description.

[0124] In some embodiments, when the watch is in an offline state, the above-mentioned second positioning scheme can be used for positioning (i.e., assisted positioning through surrounding devices). The offline state may include a power-off state, an airplane mode, etc. Taking the watch power off (for example, low-battery shutdown) as an example, one possible implementation method is that when the watch is turned off, a certain amount of power can be reserved in the watch. This reserved power can support the normal operation of the short-range communication module in the watch, so the second positioning scheme can be used for positioning. In other words, the embodiment of the present application can achieve offline positioning of the watch.

[0125] In the above embodiment, only one surrounding device is used as an example. However, it is understandable that there may be multiple surrounding devices. In this case, the following two solutions may be included.

[0126] Option 1

[0127] The watch does not care about the number of surrounding devices, it only sends a positioning request, which may be received by one surrounding device or multiple surrounding devices. If received by multiple surrounding devices, each of the multiple surrounding devices can execute S202 to S203. Therefore, the cloud will receive multiple geographic locations. At this time, the cloud can have multiple processing methods. For example, the cloud can send all multiple geographic locations to the parent's mobile phone. Alternatively, the cloud can determine a geographic location based on multiple geographic locations, and then send the determined geographic location to the parent's mobile phone. The cloud can have multiple ways to determine a geographic location based on multiple geographic locations. For example, the cloud randomly selects a geographic location from multiple geographic locations. Alternatively, the cloud draws a circle with a preset length (for example, 5 meters) as the radius with each of the multiple geographic locations as the center. In this way, multiple circles will be obtained. The cloud can determine that the overlapping area of ​​the multiple circles is the area where the child's watch is located, and send the geographic location of the area (for example, the center position of the area) to the parent's mobile phone.

[0128] Option 2

[0129] The watch monitors the number of surrounding devices. For example, if the watch determines there is only one surrounding device, it can send a positioning request to that device. If the watch determines there are multiple surrounding devices, it can identify a target device from the multiple surrounding devices and then send a positioning request to the target device. In this method, the watch needs to determine the number of surrounding devices. For example, the watch can determine the number of surrounding devices using a short-range communication module (e.g., Bluetooth). Of course, it can also determine the device types of the surrounding devices, such as device models. The specific implementation principles are not described in detail in this application. Optionally, the watch can determine the target device from multiple surrounding devices in a variety of ways. Method 1: The watch randomly selects a device from multiple surrounding devices as the target device. Method 2: The watch determines the device closest to the watch from multiple surrounding devices as the target device. Method 3: The watch determines the target device based on the device types of the multiple surrounding devices. As mentioned above, surrounding devices can include mobile devices of passersby or non-mobile devices located on the roadside, such as a drive test unit (RSU). Therefore, in Method 3, if the multiple surrounding devices include mobile devices and non-mobile devices (e.g., a drive test unit (RSU)), the watch can determine the RSU as the target device, which is more secure. It should be noted that these examples illustrate three ways for a watch to determine a target device. In actual applications, other methods can also be used to determine a target device, and this embodiment of the application does not provide examples one by one. In solution 2, after the watch determines a target device, it sends a positioning request to the target device. The target device executes S202 and S203. As a result, the cloud receives a geographic location, namely the geographic location sent by the target device, and the cloud can send this geographic location to the parent's mobile phone.

[0130] In some examples, when the watch determines that the number of surrounding devices is 0, it can output a prompt message to prompt the user to move.

[0131] As mentioned above, the cloud receives the geographic location of the watch sent by the anonymous device. In some examples, after the cloud receives the geographic location of the watch sent by the anonymous device, it can send a prompt message to the parent's mobile phone to prompt the parent to check the location of the watch. Optionally, if the cloud receives the geographic location reported by the watch itself, the prompt message may not be sent to the parent's mobile phone. For example, referring to (a) in Figure 4, a prompt message is displayed on the parent's mobile phone: The location of Huawei Watch XXX has been updated, please check immediately. Optionally, the prompt message can also be other content, for example, it can also be: Huawei Watch XXX is located by an anonymous device, please check immediately; or it can also be: Huawei Watch XXX is low on battery, please check immediately. This is because when the watch is low on battery, in order to reduce the speed of power consumption, it can use surrounding devices to assist in positioning. Therefore, after the cloud receives the geographic location of the watch sent by the anonymous device, it can infer that the watch is low on battery, so it sends a prompt message to the parent's mobile phone to remind the parent that the watch is low on battery.

[0132] Continuing with (a) in FIG4 , shortcuts may also be displayed on the mobile phone, for example, a view location button 401 and a one-touch contact button 402 .

[0133] In (a) in Figure 4, when the mobile phone receives an operation for the view location button 401, the geographic location of the watch can be quickly opened, for example, an interface as shown in (b) in Figure 4 is displayed, which includes a map, and the current location of the children's watch can be marked on the map. Optionally, the interface in (b) in Figure 4 may also include a prompt message 400 to indicate the current status of the children's watch. The current status may include the current battery level, online or offline status. Among them, the offline status includes the off state or being in flight mode. The online status includes the on state and not being in flight mode. It should be noted that the display position of the prompt message 400 is not limited in the embodiment of the present application, and is not limited to being displayed in the interface in (b) in Figure 4, and can also be displayed in other interfaces.

[0134] In (a) of FIG4 , when the mobile phone receives an operation for the one-touch contact button 402, it can contact the watch. The contact method may include any of the following (1) to (4). (1) Dial the phone number of the watch. (2) Initiate a video call to the watch, and the video call may be a video call of an instant messaging application (e.g., Huawei Changlian). (3) Initiate a voice call to the watch, and the voice call may be a voice call of an instant messaging application (e.g., Huawei Changlian). (4) Contact the watch through an auxiliary positioning device. The auxiliary positioning device is the surrounding device mentioned in FIG2B above.

[0135] In some examples, the parent's mobile phone cannot directly contact the surrounding devices (the surrounding devices are anonymous), so in (4), the parent's mobile phone can use the cloud to contact the surrounding devices, and then contact the child's watch through the surrounding devices. For example, the parent's mobile phone can send a reminder message to the cloud. After the cloud receives the reminder message, if it can contact the watch, it will send the reminder message to the watch. If it cannot contact the watch (for example, the watch is offline), it will send the reminder message to the surrounding devices. After receiving the reminder message, the surrounding devices will send the reminder message to the child's watch. As mentioned above, when the watch is offline, a portion of power can be reserved to ensure the normal use of the short-range communication module. Therefore, when the watch is offline, it can also receive reminder messages sent by surrounding devices. After receiving the reminder message, the watch can output the reminder message. The reminder message can be used to remind the child to charge as soon as possible, contact the parents as soon as possible, or go home as soon as possible, etc. Optionally, the way the watch outputs the reminder message may include: vibration, ringing, outputting text messages, outputting voice messages, etc. For example, voice playback: Please charge as soon as possible and contact the parents in time. As mentioned above, there may be multiple surrounding devices, that is, the cloud receives geographic locations reported by multiple surrounding devices. In this case, the cloud can randomly select a surrounding device and send a reminder message to the surrounding device, or send a reminder message to each surrounding device.

[0136] In other examples, the parent's phone can directly communicate with surrounding devices. For example, the surrounding device sends local information (e.g., the surrounding device's contact information) to the cloud, and the cloud sends the surrounding device's contact information to the parent's phone. In this case, the parent's phone can directly send a reminder message to the surrounding device based on the contact information. After receiving the reminder message, the surrounding device sends the reminder message to the child's watch.

[0137] In the above embodiment, the cloud receives a reminder message from the parent's phone and sends it to the child's watch via surrounding devices. In other examples, after receiving the watch's geographic location from an anonymous device, the cloud can attempt to send a reminder message to the watch (optionally, the reminder message here can be information pre-stored in the cloud). If the message is unsuccessful, the cloud sends a reminder message to the watch via surrounding devices. The reminder message can be used to prompt the watch to charge as soon as possible, contact the parent as soon as possible, or return home as soon as possible, etc.

[0138] In Figure 4 (a), when the phone receives an action on the one-touch contact button 402, it may also display the interface shown in Figure 4 (c). This interface includes multiple shortcuts for contacting the child's watch, for example, icons 403, 404, 405, and 406. Icon 403 is used for contacting the watch by phone. When the phone receives an action on icon 403, the phone places a call to the watch. Icon 404 is used for a video call. When the phone receives an action on icon 404, the phone initiates a video call request to the watch. Icon 405 is used for a voice call. When the phone receives an action on icon 405, the phone initiates a voice call request to the watch. Icon 406 is used for contacting the child's watch via an auxiliary positioning device. After the phone receives an action on icon 406, it contacts the child's watch via the auxiliary positioning device. For the specific implementation process, please refer to the previous description. Optionally, the mobile phone can also open the interface (c) in Figure 4 in other ways. For example, in Figure 4 (b), when the mobile phone receives an operation for the prompt information 400, it can also open the interface (c) in Figure 4.

[0139] In the above embodiments, in (c) of FIG4 , a mobile phone is shown as displaying four icons (e.g., icon 403, icon 404, icon 405, and icon 406). In actual applications, more or fewer icons may be displayed. For example, an icon corresponding to a text message may also be displayed, through which a text message may be sent to the children's watch.

[0140] In the above embodiment, in (c) of Figure 4, four icons (for example, icon 403, icon 404, icon 405 and icon 406) are displayed on the mobile phone, corresponding to four contact methods respectively. Optionally, although not shown in (c) of Figure 4, the mobile phone can also display: for each of the four contact methods, the duration that the watch can support. Taking icon 404 as an example, icon 404 corresponds to a video call, and the mobile phone can also display the duration of the video call supported by the watch. For example, the mobile phone can display prompt information 1: the watch can support 20 minutes of video calls. Taking icon 405 as an example, icon 405 corresponds to a voice call, and the mobile phone can also display the duration of the voice call supported by the watch. For example, the mobile phone can display prompt information 2: the watch can support 30 minutes of voice calls. It should be noted that the embodiment of the present application does not limit the display position of prompt information 1, prompt information 2, etc. on the mobile phone.

[0141] In (c) of Figure 4 , a mobile phone displays four icons (i.e., icon 403, icon 404, icon 405, and icon 406) as an example. In other embodiments, the number and / or display status of the four icons can change dynamically. For example, the number and / or display status of the four icons can change with the current state of the watch. The current state of the watch includes the current battery level of the watch, online status, offline status, etc.

[0142] Take the example of the number and / or display status of four icons that change dynamically with the current battery level of the watch. For example, when the current battery level of the watch is greater than or equal to a preset value (e.g., 20%), all four icons are displayed. When the current battery level of the watch is less than a preset value (e.g., 20%), only some of the icons may be displayed, such as only icons for contact information with lower power consumption, such as only icons 403, 405, and 406, while icon 404 (the video call icon) is not displayed. Alternatively, only icons 405 and 406 may be displayed, while icon 403 (the phone icon) and icon 404 (the video call icon) are not displayed. Taking icon 404 as an example, the reason for not displaying icon 404 is that if the watch does not have sufficient battery power, if the video call icon 404 is displayed on the phone, the parent may accidentally touch the icon and initiate a video call to the watch, thereby increasing the power consumption of the watch. Therefore, icon 404 may not be displayed on the phone. Alternatively, when the current battery level of the watch is less than a preset value (e.g., 20%), all four icons may be displayed. To prevent the user from triggering a video call, icon 404 is displayed in grayscale (i.e., grayed out). When the user clicks icon 404, a video call will not be initiated to the watch.

[0143] Take the example of the number and / or display status of four icons that change dynamically with the online or offline status of the watch. For example, when the watch is online, the mobile phone can display four icons. When the watch is offline, the mobile phone can only display icon 406, which is an icon for contacting the watch through an auxiliary device. For example, please refer to (a) in Figure 5, the mobile phone displays an interface, which includes a prompt message 400: Offline. When the mobile phone receives an operation for the prompt message 400, it can display an interface as shown in (b) in Figure 5, which includes icon 406. When the mobile phone receives an operation for icon 406, it contacts the watch through the auxiliary positioning device. Please refer to the previous text for the specific implementation principle, which will not be repeated here.

[0144] In the above embodiments, two positioning schemes are provided, namely the first positioning scheme (by GPS positioning) and the second positioning scheme (by auxiliary positioning of surrounding devices), which can also be referred to as two positioning modes. In some examples, the watch includes only one positioning scheme, for example, the watch is configured with only one positioning scheme by default when it leaves the factory, and the positioning scheme can be any one of the above two positioning schemes. In other examples, the watch includes both of the above positioning schemes, for example, the watch is configured with both of the above positioning schemes by default when it leaves the factory, and the watch can choose to use one of the two positioning schemes. The following, in conjunction with Figures 6A and 6B, illustrates how to locate when the watch includes two positioning schemes.

[0145] Please refer to Figure 6A, which is a schematic diagram of a wearable device provided in one embodiment of the present application. Figure 6A takes the wearable device as an example, a watch, which includes positioning module A and positioning module B. Positioning module A includes GPS and a long-distance communication module, which can implement the first positioning solution described above. Positioning module B includes a short-distance communication module, which can implement the second positioning solution described above.

[0146] Please refer to Figure 6B, which is a flowchart of a positioning method provided in one embodiment of the present application. This method can be applied to the watch in Figure 6A. As shown in Figure 6B, the process includes:

[0147] S600, the watch has the positioning function turned on.

[0148] In some examples, the positioning function can be turned on manually or automatically. Taking manual turning on as an example, the watch may include a switch for starting and stopping the positioning function. For example, referring to (a) in FIG7 , the watch displays an interface for setting up the application, which includes an option for the positioning function. When the watch receives an operation for the option of the positioning function, an interface as shown in (b) in FIG7 may be displayed, which includes a switch 700 for the positioning function. The user can manually start and stop the positioning function through the switch 700. Taking automatic turning on as an example, for example, when the watch detects that at least one of the following conditions is met, the positioning function can be automatically started. The conditions include:

[0149] Condition 1: The current time is within a preset time period. For example, considering that children tend to go out during the day and are more likely to get lost, but are less likely to get lost at home at night, the positioning function can be activated during the day. For example, the preset time period can be from 8:00 AM to 8:00 PM. Optionally, the preset time period can be set by the watch system by default or manually set by the user, and this embodiment of the application is not limited thereto.

[0150] Condition 2: Long period of inconvenience with parents. For example, if the watch determines that there has been no contact with parents (e.g., phone call, video / voice call, etc.) for a first preset time, the positioning function is automatically activated. The first preset time can be 2 hours, 3 hours, etc., and is not limited in this embodiment of the application.

[0151] Condition three: The watch has not been used for a long time. For example, if the watch detects that the screen has been black for a second preset time, the positioning function will be automatically activated.

[0152] It should be noted that in addition to the above three conditions, there may be other conditions, which are not limited in the embodiments of the present application.

[0153] In the above embodiments, the positioning function in the watch can be manually started or automatically started. In addition to these two methods, the positioning function of the watch can also be started in other ways. For example, the parent's mobile phone can control the start and stop of the positioning function of the watch. For example, after the watch receives an instruction from the parent's mobile phone to start the positioning function, it starts the positioning function. After the watch receives an instruction from the parent's mobile phone to turn off the positioning function, it turns off the positioning function. Among them, the process of parents controlling the start and stop of the positioning function of the watch on the mobile phone is not described in detail in the embodiments of the present application. For example, a switch that can control the positioning function of the child's watch is displayed on the parent's mobile phone, and the parent controls the start and stop of the positioning function of the child's watch through the switch.

[0154] In the embodiment of the present application, after the watch starts the positioning function, since the watch includes two positioning solutions, the watch can further determine which positioning solution to use.

[0155] In some examples, the user can manually select which positioning scheme to use. For example, continuing with Figure 7 (b), when the watch receives a swipe-up action, it may display the interface shown in Figure 7 (c), which includes options for two positioning schemes. When the user selects positioning mode A, the first positioning scheme is used; when the user selects positioning mode B, the second positioning scheme is used. In other examples, the watch can independently determine which positioning scheme to use. The automatic determination process includes S601 to S603, which will be described later. Of course, in addition to manually or automatically selecting a positioning scheme, there are other ways to determine the positioning scheme. For example, a parent's phone can control which positioning scheme the watch uses. For example, after receiving instruction 1 sent by the parent's phone, the watch uses the first positioning scheme, and after receiving instruction 2 sent by the parent's phone, it uses the second positioning scheme. The process of the parent controlling the watch's positioning scheme on the phone is not described in detail in this embodiment of the application. For example, the parent's phone may display options for the watch's two positioning schemes, and the parent can select one of the two positioning schemes.

[0156] S601, the watch performs condition detection. When it is detected that the first condition is met, S602 is executed (i.e., the second positioning solution is used). When it is detected that the second condition is met, S603 is executed (i.e., the first positioning solution is used).

[0157] Among them, condition detection can include: power detection, load detection, time detection, geo-fence detection, etc.

[0158] Optionally, the first condition may include at least one of the following:

[0159] Condition a: The watch is currently low on battery. It should be noted that in the second positioning solution, the watch uses surrounding devices to assist in positioning, which consumes relatively less power. Therefore, if the watch is currently low on battery, the second positioning solution can be used to save power. The watch's current low battery may include: the watch's current battery is less than or equal to threshold 1. Threshold 1 can be 30%, 20%, 10%, etc., and is not limited in this embodiment of the application.

[0160] Condition b: The watch is currently under a heavy load. It should be noted that in the second positioning solution, the watch is assisted in positioning by surrounding devices, so the power consumption generated by the watch is relatively small. If the watch is currently under a heavy load, the second positioning solution can be used to reduce power consumption. Optionally, the watch's current heavy load may include: the watch's current CPU usage is relatively high (for example, the current CPU usage is greater than or equal to threshold 2), the current storage space occupancy is relatively high (for example, the current storage space occupancy is greater than or equal to threshold 3), etc.

[0161] Condition c, the current time is within the first preset time period. In the embodiment of the present application, it is taken into account that the probability of a child getting lost is small during certain time periods. For example, during the school time period, the probability of a child getting lost is small, so the second positioning scheme can be used during this time to save power consumption. Optionally, the first preset time period can be a system default setting or a user setting, which is not limited in the embodiment of the present application. It should be noted that the above mentioned watch starts the positioning function when it detects that the current time is in a preset time period (for example, 8 am to 8 pm). The first preset time period here can be a period of time in the preset time period mentioned above.

[0162] Condition d, the current location is within the first geo-fence. It should be noted that, considering that in certain locations, the probability of a child getting lost is small. For example, at school or at home, the probability of a child getting lost is small. Therefore, at these locations, the second positioning scheme can be used to save power consumption. Optionally, the first geo-fence can be a system default setting or a user setting, which is not limited in the embodiments of the present application. It should be noted that one way to implement condition d is that after the watch starts the positioning function, the first positioning scheme (i.e., GPS positioning) is first used to detect the current geographic location. If it is determined that the current geographic location enters the first geo-fence (for example, school), the second positioning scheme can be used; if the current geographic location is not within the first geo-fence, the first positioning scheme continues to be used. Optionally, after the watch detects through GPS that the watch has entered the first geo-fence, the GPS can be turned off.

[0163] It should be noted that the above four conditions (conditions a to d) are only examples. In actual applications, more or fewer conditions than the above four conditions may be included, and the embodiments of this application are not limited thereto.

[0164] Optionally, the second condition may include at least one of the following:

[0165] Condition e: The watch currently has sufficient power. It should be noted that the first positioning solution requires the use of GPS positioning, which consumes a lot of power. If the watch currently has sufficient power, the first positioning solution can be used to improve the accuracy of positioning. The watch currently has sufficient power, which can include: the watch's current power is greater than threshold 4. It should be noted here that the threshold 1 mentioned above, the threshold 4 here can be the same as or different from the threshold 1 mentioned above. Taking the example that threshold 1 and threshold 4 are the same and both are 20%, when the watch power is greater than 20%, the first positioning solution is used, and when the watch power is less than or equal to 20%, the second positioning solution is used.

[0166] Condition f, the current load of the watch is small. It should be noted that the first positioning solution requires the use of GPS positioning and the use of long-distance communication to send the geographic location, which will generate greater power consumption. If the current load of the watch is small, the first positioning solution can be used to improve the accuracy of positioning. Optionally, the current load of the watch is small, which may include: the current CPU usage of the watch is small (for example, the current CPU usage is less than the threshold 5), the current storage space occupancy is small (for example, the current storage space occupancy is less than the threshold 6), etc. It should be noted here that the threshold 5 here may be the same as or different from the threshold 2 mentioned above. The threshold 6 here may be the same as or different from the threshold 3 mentioned above.

[0167] Condition g: The current time is within the second preset time period. It should be noted that, as mentioned above, when the watch detects that the current time is within the preset time period (e.g., 8 a.m. to 8 p.m.), the positioning function is activated. The second preset time period here can be a period within the preset time period mentioned above. Furthermore, as mentioned above, when the watch detects that the current time is within the first preset time period, the second positioning solution is used. The second preset time period here can be the remaining time period within the preset time period excluding the first preset time period.

[0168] Condition h: The current location is not within the first geofence. Please refer to the previous article for details about the first geofence. It should be noted that, as mentioned above, if the watch is within the first geofence (for example, a school), the second positioning scheme will be used. Therefore, within the first geofence, the watch is assisted in positioning by surrounding devices. For example, the watch can receive the geographic location sent by surrounding devices. If the watch determines that the watch has moved out of the first geofence based on the geographic location sent by surrounding devices, it switches to the first positioning scheme.

[0169] It should be noted that the above four conditions (conditions e to h) are only examples. In actual applications, more or fewer conditions than the above four conditions may be included, and the embodiments of this application are not limited thereto.

[0170] S602: The watch executes the second positioning solution.

[0171] It is understandable that if the positioning module B is in an off state before S602 , the positioning module B can be turned on and then the second positioning solution is executed.

[0172] S603: The watch executes the first positioning solution.

[0173] It is understandable that if the positioning module A is in an off state before S603 , the positioning module A can be turned on and then the first positioning solution is executed.

[0174] In some embodiments, it is possible to switch between the first positioning scheme and the second positioning scheme. This switching can be done manually by the user or automatically by the watch. For example, in Figure 7 (c), the user can manually switch between positioning modes A and B. For example, automatic switching includes the following two scenarios.

[0175] Case 1: The watch currently uses the first positioning scheme (GPS positioning). When it detects that the third condition is met, it switches from the first positioning scheme to the second positioning scheme (assisted positioning). Exemplarily, the third condition may include at least one of the conditions a, b, c, d, and i mentioned above. In case of condition i, the first positioning scheme fails (for example, the GPS cannot locate the location or send the geographic location to the cloud due to poor network signal).

[0176] Case 2: The watch is currently using the second positioning scheme. When it detects that the fourth condition is met, it switches from the second positioning scheme to the first positioning scheme. For example, the fourth condition may include at least one of the conditions e, f, g, h, and j described above, as well as the following condition. In case of condition j, the second positioning scheme fails (for example, if the watch detects zero surrounding devices, the second positioning scheme cannot be used).

[0178] In addition, in the above embodiments, the example of a parent checking a child's location via a mobile phone is used. It is understood that the mobile phone can also be replaced with other devices. For example, it can be a PC, or a wearable device such as a watch or bracelet, or a vehicle-mounted device, or a household appliance, etc., and the embodiments of the present application are not limited thereto.
