DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with aspects related to the present disclosure as recited in the appended claims.

FIG. 1 is a flowchart of a method 100 for locating a wearable device, according to an exemplary embodiment. For example, the method 100 may be used in a wearable device. The wearable device may be a smart device capable of being directly worn by a user, such as a smart wristband or a smart watch. After the wearable device is disconnected from a first terminal, the method 100 may be used to enable the wearable device to be quickly located by other terminals. Referring to FIG. 1, the method 100 includes the following steps.

In step S102, the wearable device determines whether a short range communication connection between the wearable device and a first terminal is disconnected.

In exemplary embodiments, the wearable device has a detection function capable of detecting whether the wearable device is connected to or disconnected from the first terminal. The wearable device may activate such bidirectional detection function when the wearable device is connected to the first terminal. The short range communication connection refers to a wireless connection available only within a certain distance range, for example, a Bluetooth connection, a Near Field Communication (NFC) connection, and the like.

In step S104, if the wearable device determines that the short range communication connection with the first terminal is disconnected, the wearable device broadcasts a notification message. The notification message instructs at least one second terminal to establish a short range communication connection with the wearable device and to send a connection notification to a server so that the server locates the wearable device according to the at least one second terminal.

In exemplary embodiments, the wearable device broadcasts the notification message using Bluetooth, or any other radio signals, such as a wireless local area network or base station signals. The notification message is configured to notify at least one second terminal within a certain distance from the wearable device that the wearable device is disconnected from the first terminal. The notification message also requests to establish a short range communication connection between the wearable device and the at least one second terminal. The notification message is further configured to instruct the at least one second terminal to notify the server that at least one second terminal has established the connection with the wearable device, so that the server can obtain the location of the at least one second terminal to quickly locate the wearable device.

In some embodiments, the notification message may include identity information of a user who uses the wearable device and a signal for requesting assistance. The notification message may be further configured to instruct the at least one second terminal to report to the server location information of the at least one second terminal and the identity information of the user. If the notification message includes the identity information and the signal for requesting assistance, the at least one second terminal may obtain the location information of the at least one second terminal via a Global Positioning System (GPS), and report the identity information and the location information to the server. The server can locate the missing wearable device according to the location information of the at least one second terminal, and quickly locate the wearable device.

According to the method 100, after a wearable device is disconnected from a first terminal, the wearable device broadcasts a notification message. After a short range communication connection between the wearable device and at least one second terminal is established, the at least one second terminal reports the identity of the wearable device to a server. The server locates the wearable device according to the at least one second terminal. Therefore, the method 100 can quickly determine the location of the wearable device after the wearable device is disconnected from the first terminal, and improve the speed and accuracy for locating the wearable device.

FIG. 2 is a flowchart of a method 200 for locating a wearable device, according to an exemplary embodiment. For example, the method 200 may be used in a wearable device. Referring to FIG. 2, the method 200 is described on the basis of the embodiment shown in FIG. 1 and includes the following steps.

In step S202, the wearable device obtains identity information of a user who uses the wearable device.

After establishing a connection, e.g., a short range communication connection, with a first terminal, the wearable device may obtain the identity information of the user using the wearable device. For example, the identify information may include name, guardian (e.g., if the user is a child), contact numbers, home address, and the like. In exemplary embodiments, the identity information may be obtained according to at least the following two approaches.

In the first approach, the wearable device receives the identity information sent by the first terminal, and locally stores the received identity information. For example, a user can input the identity information on the first terminal and then send the identity information to the wearable device.

In the second approach, the wearable device collects the identity information directly input by a user on the wearable device, and locally stores the identity information. For example, the wearable device may have an input interface, such as a touch screen, a microphone or, or a display, for the user to directly enter the identity information into the wearable device.

In step S204, the wearable device determines whether the short range communication connection between the wearable device and the first terminal is disconnected.

In step S206, if the wearable device determines that the short range communication connection with the first terminal is disconnected, the wearable device broadcasts a notification message. The notification message includes the identity information of the user who uses the wearable device and a signal for requesting assistance. The notification message is further configured to instruct at least one second terminal to report to a server the location information of the at least one second terminal and the identity information of the user.

In exemplary embodiments, when determining that the short range communication connection between the wearable device and the first terminal is disconnected, the wearable device broadcasts the notification message to at least one second terminal that is in proximity to the wearable device. The wearable device may broadcast the notification message via Bluetooth, a wireless local area network, or a base station signal.

The notification message instructs the at least one second terminal to establish a short range communication connection with the wearable device. If the at least one second terminal agrees to form the connection, the at least one second terminal may activate a short range communication function to establish the connection with the wearable device, and then notify the server of the location information of the at least one second terminal and the identity information of the user who uses the wearable device, so that the server can locate the wearable device.

In exemplary embodiments, the short range communications between the wearable device and the first terminal or the second terminals include but not limited to Bluetooth connections. In one embodiment, the connection may be formed via Bluetooth technology, so as to save power and reduce cost.

According to the method 200, before the wearable device is disconnected from the first terminal, the wearable device obtains identity information of a user who uses the wearable device, so that the wearable device can send the identity information and requesting-assistance information to second terminals when the connection is disconnected. The wearable device may broadcast the notification message in any suitable manners, such as via Bluetooth, via a wireless local area network, or via base station signals. This way, the wearable device may be located quickly and accurately.

FIG. 3 is a flowchart of a method 300 for locating a wearable device, according to an exemplary embodiment. For example, the method 300 may be used in a second terminal. The second terminal may be a device with a short range communication function, such as a mobile phone, a laptop, a tablet computer, and the like. The method 300 includes the following steps.

In step S302, the second terminal receives a notification message broadcast by a wearable device. The notification message is configured to instruct the second terminal to establish a short range communication connection with the wearable device and to report a connection notification to a server.

In step S304, the second terminal establishes the short range communication connection with the wearable device, and sends a connection notification to the server, so that the server locates the wearable device according to the second terminal. The connection notification is configured to indicate that the second terminal has established the short range communication connection with the wearable device.

In exemplary embodiments, the second terminal is one of the devices that is in proximity to the wearable device and are located within a range suitable for short range communications. After the second terminal receives the notification message broadcast by the wearable device and authorizes the establishment of a connection with the wearable device, the second terminal sends the connection notification to the server.

The connection notification may carry the identity of the wearable device, so that the server can distinguish multiple wearable devices according to identities and locate the wearable device that needs to be located.

According to the method 300, after receiving a notification message from a nearby wearable device, the second terminal establishes a connection with the wearable device, and reports to the server that the second terminal has established a connection with the wearable device, so that the server locates the wearable according to the second terminal. In this manner, a missing wearable device can be quickly located.

FIG. 4 is a flowchart of a method 400 for locating a wearable device, according to an exemplary embodiment. For example, the method 400 may be used in a second terminal. Referring to FIG. 4, the method 400 is described on the basis of the embodiment shown in FIG. 3, and includes the following steps.

In step S402, the second terminal receives a request, from a server, for activating a monitoring function of the second terminal.

In step S404, the second terminal activates, according to the request, a short range communication detection function.

In step S406, the second terminal receives a notification message broadcast by a wearable device. The notification message is configured to instruct the second terminal to establish a short range communication connection with the wearable device and to report a connection notification to the server.

In step S408, the second terminal establishes the short range communication connection with the wearable device, and sends the connection notification to the server.

In step S410, the second terminal reports to the server location information of the second terminal and identity information of the user who uses the wearable device.

In exemplary embodiments, after the first terminal detects that the first terminal is disconnected from the wearable device, the first terminal obtains the location information of the first terminal, and sends the location information and/or the nearby base station information to the server. The first terminal also sends to the server a request for locating the wearable device. After receiving the request, the server sends a request for activating a monitoring function to one or more second terminals, such as mobile phones, in proximity to the first terminal. If a second terminal accepts the request, the second terminal activates the detection function and establishes a short range communication connection with the wearable device.

The one or more second terminals may use a GPS function to obtain the location information of each second terminal Each second terminal reports the location information of the second terminal and the identity information of the user who uses the wearable device to the server. The server may locate the wearable device according to the location information of the one or more second terminals, and notify the first terminal that the wearable device is located.

In some embodiments, in order to save power and reduce costs, the short range communication connection established between the second terminal and the wearable device may be a Bluetooth connection. The connection between the wearable device and the first terminal may also be a Bluetooth connection.

According to the method 400, a second terminal in proximity to the first terminal receives instructions from the server to activate a short range communication detection function of the second terminal. The server then controls the second terminal to locate the wearable device. In this manner, after the wearable device is lost, the wearable device can be located using the location information of the second terminals that are in proximity to the first terminal and form a connection with the wearable device.

FIG. 5 is a flowchart of a method 500 for locating a wearable device, according to an exemplary embodiment. For example, the method 500 may be used in a server. Referring to FIG. 5, the method 500 includes the following steps.

In step S502, the server receives, from a first terminal, location information of the first terminal and requesting-assistance information. The requesting-assistance information indicates that the first terminal is disconnected from a wearable device.

In step S504, the server sends, according to the location information of the first terminal, a request for activating a monitoring function to at least one second terminal within a preset distance from the first terminal Based on the request, the at least one second terminal activates a short range communication detection function to establish a short range communication connection with the wearable device.

In step S506, the server receives, from the at least one second terminal, location information of the at least one second terminal and identity information of a user who uses the wearable device, and locates the wearable device according to the location information of the at least one second terminal

According to the method 500, the server receives, from the first terminal, the location information of the first terminal and requesting-assistance information. The requesting-assistance information indicates that the first terminal is disconnected from the wearable device and requests the server to locate the wearable device. According to the location information of the first terminal, the server sends a request for activating a monitoring function to at least one second terminal within a preset distance from the first terminal. The at least one second terminal reports the location information of the respective second terminal to the server. By controlling the second terminals in proximity to the wearable device, the server may accurately and efficiently locate the wearable device.

FIG. 6 is a flowchart of a method 600 for locating a wearable device, according to an exemplary embodiment. For example, the method 600 may be performed by a system including a wearable device, at least one second terminal, and a server. Referring to FIG. 6, the method 600 includes the following steps.

In step S602, the wearable device determines whether a connection between the wearable device and a first terminal is disconnected.

In step S604, after the wearable device determines that the connection with the first terminal is disconnected, the wearable device broadcasts a notification message.

In step S606, at least one second terminal receives the notification message and activates a short range communication detection function.

In step S608, the at least one second terminal establishes a short range communication connection with the wearable device.

In step S610, the at least one second terminal reports to the server a connection notification, location information of the at least one second terminal, and identity information of the user who uses the wearable device.

In step S612, the server locates the wearable device according to the location information of the at least one second terminal, and obtains the location information of the wearable device.

Optionally, after the first terminal detects the disconnection from the wearable device, the first terminal may send the server the location information of the first terminal and a request for locating the wearable device. The server may then provide the location information of the wearable device to the first terminal, so that the first terminal can locate the wearable device.

The methods disclosed in the above embodiments may be used for finding lost wearable devices, or for locating missing children or elders through the wearable devices worn by the children or elders. The wearable device may take the form of portable accessories that have computation capabilities and are connectable to mobile phones and other types of terminals. For example, the wearable devices may include watch type products worn on a user's wrist, such as smart watches, smart wristbands, smart bracelets, and the like. The wearable devices may also include shoes type products worn on the user's feet or legs, such as shoes, stockings, and the like. The wearable devices may also include glasses type products worn on the user's head, such as smart glasses, helmets, head bands, and the like. The wearable devices may further include smart clothing, schoolbags, walking sticks, fashion accessories, etc. The present disclosure does not limit the types and forms of the wearable devices.

The following are two examples illustrating the above-described methods. In the first example, a smart wristband is worn by a child. The smart wristband may establish a Bluetooth connection with a mobile phone (i.e., a first mobile phone) of the child's parents. The smart wristband may activate a bi-directional detection function, so that the smart wristband may detect whether the smart wristband is disconnected from the first mobile phone. When the disconnection is detected, the smart wristband broadcasts a notification message via Bluetooth or other radio communication technologies, such as WiFi. If one or more second mobile phones in the vicinity of the smart wristband agree to form a connection with the smart wristband, each second mobile phone may perform Bluetooth scanning at a predetermined time interval, so as to establish a Bluetooth connection with the smart wristband. Each second mobile phone then reports to a server that the second mobile phone has established a connection with the smart wristband. Subsequently, the server may locate the smart wristband according to the one or more second mobile phones.

In the second example, after the first mobile phone detects that the Bluetooth connection with the smart wristband is disconnected, the first mobile phone automatically reports the location information of the first mobile phone and/or the base station information to the server. The server automatically controls the second mobile phones in the vicinity of the first mobile phone and/or the base stations to activate the respective Bluetooth monitoring functions. If the second mobile phones activate the monitoring functions and establish Bluetooth connections with the smart wristband, the second mobile phones may promptly report the GPS information of the second mobile phones and the identity information of the smart wristband to the server. The server then locates the smart wristband according to the GPS information and the identity information.

According to the methods in the present disclosure, the wearable device or the server triggers the terminals in proximity to the wearable device to enter into a monitoring mode, so as to monitor the information broadcast by the wearable device. The terminals establish connections with the wearable device and report their respective location information to the server. The server then locates the wearable device according to the location information of the terminal in proximity to the wearable device. In preferred embodiments, the connections between the wearable device and the terminals may be Bluetooth connections, so as to reduce costs.
