Hereinafter, the operation of the mobile positioning system 100 (ie, the mobile positioning method of the present invention) will be separately described with a plurality of embodiments.

Referring to FIGS. 1, 2A, and 2B, in an embodiment of the present invention, the user of the electronic device 180 can remotely open the SIM card 161 of the target device 160 through the mobile positioning system 100. In general, for the target device 160 that has not been used or has just been shipped, the SIM card 161 in the card holder 162 has not been activated yet, so the network service provided by the telecommunications provider cannot be utilized. In this embodiment, the user can use the operation input interface 182 of the electronic device 180 and the display unit 188 to input the product serial number of the target device 160. When the electronic device 180 receives the product serial number of the target device 160 through the operation input interface 182, the second processing unit 186 transmits the product serial number and the call number of the electronic device 180 to the remote server 120 through the second communication interface 184. In this embodiment, the call number of the electronic device 180 is, for example, a phone number assigned by a telecommunications provider, but the present invention is not limited to this.

In this embodiment, the service database 140 stores the card information of the SIM card 161 of the target device 160. Therefore, after searching the service database 140 based on the product serial number, the remote server 120 can obtain the card information of the SIM card 161 of the target device 160 and accordingly activate the SIM card 161 of the target device 160. Only after the SIM card 161 of the target device 160 is activated, can the target device 160 use the network service provided by the telecommunications provider.

In an embodiment of the invention, the mobile positioning system 100 can further locate and monitor the geographic location of the target device 160. FIG. 3 is a schematic diagram of the positioning of the object device according to the embodiment of the invention. Referring to FIG. 3, the first processing unit 166 of the target device 160 may acquire the first geographic position (eg, latitude and longitude) of the target device through the satellite locator 165 at regular time or based on instructions, based on the number of satellites used to obtain the first geographic position and the response The signal strength of determines the corresponding error, and sends the first geographic location and its error to the remote server 120 through the first communication interface 164.

Although satellite positioning technology can provide more accurate geographic information for outdoor positioning, its indoor positioning may be due to poor signal strength (below a specific decibel value) or too few satellites (below 3, 2 etc.) Quite possibly, it may not be able to provide positioning due to the lack of satellite signals. The remote server 120 according to the embodiment of the present invention also determines the second geographic location (eg, latitude and longitude, at a specific address or location) of the target device 160 according to the location information of the network access point BS (eg, actual latitude and longitude or address, etc.) The relative position of the building, etc.).

For example, the network access point BS is a base station, and the first processing unit 166 periodically transmits data packets through the first communication interface 164 to the network access point BS to which the target device 160 is connected. The foregoing data packets are, for example, beacon packets, text message packets, voice packets, etc., but the invention is not limited thereto. The remote server 120 obtains the base station information (eg, actual latitude, longitude, or address, etc.) of the network access point BS, the location of the neighboring base station, and the inter-side distance (ISD) from the service database 140, In the past, information such as positioning records, and the second geographic location and corresponding error of the target device 160 are estimated based on the base station information and the aforementioned other information. In more detail, based on the base station position of the base station BS and the data packet of the target device 160, the remote server 120 uses base station positioning such as Observed Time Difference of Arrival (OTDOA), triangulation, etc. In other words, the second geographic location of the target device 160 can be estimated accordingly.

Then, the remote server 120 selects the smallest one of the first and second geographic locations as the third geographic location in the geographic information of the target device 160 according to the corresponding errors of the first and second geographic locations, respectively. The smallest error of the two is regarded as the corresponding error of the third geographic location of the target device 160 and is carried in the geographic information of the target device 160. The remote server 120 will further transmit this geographic information to the electronic device 180, and the second processing unit 186 of the electronic device 180 can present the third geographic location and its error through the display unit 188. For example, the display unit 188 presents the third geographic location on the electronic map at the corresponding coordinates as the positioning center point; and when the error exceeds a certain size threshold (for example, 500 meters, 1 km, 5 km, etc.), the display unit 188 will use The center point of the positioning is the center of the circle and presents a specific range (for example, this range is a circle, and the error returned by the remote server 120 may be the radius of this range, or other corresponding values) visually; if the error does not exceed In the aforementioned threshold of size, the display unit 188 may only display the positioning center point. In this way, it is convenient for the user to know the error status of the current geographic information, so as to further apply this geographic information.

It should be noted that the above-mentioned graphical representation of geographic information is easier for users to understand. However, in other embodiments, the electronic device 180 may present the geographic information of the target device 160 in a numerical, graphical, etc. manner. The invention is not limited. In addition, the positioning technology for other types of network access points BS may change due to different location information, and the corresponding error may be based on the location of neighboring access points, the distance between access points and the past geographic information (e.g. The estimated geographic information and its corresponding error several times, or the error caused by the same network access point BS or the adjacent network access point BS in the past), and the implementer of the present invention can adjust it according to his needs .

It can be seen that the embodiments of the present invention combine two technologies of satellite positioning and network access point positioning (the signal of the network access point BS penetrates the building more strongly than the satellite positioning signal), so regardless of whether the target device 160 is Outdoor or indoor, the remote server 120 can provide relatively accurate geographic information to the electronic device 180, thereby providing comprehensive monitoring.

It is worth noting that in response to the operation input interface 182 of the electronic device 180 receiving the user's sharing operation of the geographic information of the target device 160, the second processing unit 186 will pass the network access point BS through the second communication interface 184 Or directly communicate with the third communication interface 194 of the second electronic device 190, through a transmission method such as SMS, E-mail, Bluetooth transmission, instant messaging software, etc., so that the third processing unit 196 obtains the object shared by the electronic device 180 The geographic information of the device 160 (perhaps information such as latitude and longitude, screenshot of the electronic map, address, relative position with the building, etc.), and the geographic information of the target device 160 can be presented through its display unit 198 accordingly.

On the other hand, in this embodiment, the user can use the operation input interface 182 of the electronic device 180 to select a specified area range AR, and when the tracked person wearing the target device 160 leaves the specified area range AR, the mobile positioning system 100 Send a notification signal to the electronic device 180. For example, the user may circle a specified area AR corresponding to the map displayed by the display unit 188.

In this embodiment, when the electronic device 180 receives the specified area range AR from the operation input interface 182, the electronic device 180 transmits the specified area range AR to the remote server 120 through the second communication interface 184. After receiving the aforementioned specified area range AR, the remote server 120 determines whether the target device 160 is located outside the specified area range AR based on the geographic location of the target device 160. If so, the remote server 120 transmits the notification message IM to the electronic device 180. At this time, the display unit 188 of the electronic device 180 may display a prompt screen based on the received notification message IM to warn the user of the electronic device 180.

It is worth noting that in an embodiment of the present invention, when the remote server 120 does not detect the data packet transmitted by the target device 160 within a period of time, the remote server 120 also transmits the notification message to the electronic The device 180, and the display unit 188 of the electronic device 180 may display a prompt screen based on the received notification message IM to warn the user of the electronic device 180. In another embodiment of the present invention, when the electronic device 180 does not detect the data packet transmitted by the target device 160 for a period of time, the display unit 188 of the electronic device 180 displays a prompt screen to warn the use of the electronic device 180 By. The aforementioned time period is, for example, 30 minutes, 1 hour, 3 hours, 12 hours, or one day, and can be set by the electronic device 180 by itself or by the user of the electronic device 180 through the operation input interface 182.

In an embodiment of the invention, the mobile positioning system 100 can also use a satellite positioning system to locate and monitor the positioning coordinates of the target device 160. FIG. 4 is a schematic diagram of coordinate positioning of an object device 160 according to an embodiment of the invention. Referring to FIG. 4, the user can use the operation input interface 182 of the electronic device 180 to input a position query request, thereby activating the function of the satellite locator 165 of the target device 160 and acquiring the positioning coordinates of the target device 160.

In this embodiment, when the electronic device 180 receives the location inquiry request from the operation input interface 182, the electronic device 180 transmits the location inquiry request to the remote server 120 through the second communication interface 184. The remote server 120 transmits a remote positioning activation command to the target device 160 based on the location inquiry request. The target device 160 receives the remote positioning activation command through the first communication interface 164, and the first processing unit 166 activates the positioning function of the satellite locator 165 based on the remote positioning activation command, and periodically transmits the first geographic location through the first communication interface 164 Position FC to the remote server 120. In this way, the remote server 120 can obtain the precise first geographic location FC of the target device 160. The remote server 120 can also transmit the first geographic location FC of the target device 160 to the electronic device 180 for the user to confirm through the display unit 180.

In another embodiment of the present invention, the second processing unit 186 of the electronic device 180 also uses the positioning function of the global positioning system (GPS) to obtain the geographic location SC of the electronic device 180, and transmits it periodically through the second communication interface 184 The geographic location SC to the remote server 120. When the remote server 120 determines that the distance D between the target device 160 and the electronic device 180 exceeds the distance threshold based on the first positioning coordinate FC and the geographical position SC, the remote server 120 transmits a notification message IM to the electronic device 180. At this time, the display unit 188 of the electronic device 180 displays a prompt screen to warn the user of the electronic device 180. In this embodiment, the distance threshold can be set by the electronic device 180 or set by the user of the electronic device 180 through the operation input interface 182, and is, for example, 2 meters, 5 meters, 10 meters, 100 meters, 500 meters or 1 km, but not limited to this.

In another embodiment of the present invention, when the display unit 188 displays the prompt screen based on the notification message IM, for example, the user of the electronic device 180 can further request the corresponding service platform, such as a police station or medical institution, based on demand A service request is issued to search or rescue the tracked person wearing the target device 160. In other words, when a prompt screen is displayed, if the service input interface 182 receives the service request, the electronic device 180 connects to the corresponding service platform through the second communication interface 184 and transmits the service request to the service platform.

In an embodiment of the present invention, when the power of the power supply 168 of the target device 160 is lower than the power threshold, the first processing unit 166 transmits the low power message to the electronic device 180 or the remote server through the first communication interface 164器120. The power threshold can be set by the electronic device 180 by itself or by the user of the electronic device 180 through the operation input interface 182, and is, for example, 20% or 15% of the total power of the power supply device 168, but not limited thereto. On the other hand, in order to save power, the target device 160 periodically enters the sleep mode, and cuts off the power supply of some components.

In addition to the aforementioned monitoring of a single object device 160, in another embodiment, please refer to FIG. 5 which is a schematic diagram of a mobile positioning system 100 according to another embodiment of the present invention.
