Description

Tracking and positioning device and tracking and positioning method

The present invention relates to a technology suitable for tracking user devices, and particularly relates to a tracking positioning device and a tracking positioning method.

With the popularity of smartphone application services, various positioning-related services have brought people more convenient lives. The positioning needs of these services are mostly initiated by terminal devices. For example, when users need map navigation, finding nearby restaurants, stores, and searching for nearby discounts, the user actively activates the positioning function through the terminal device. Most of the above-mentioned services use GPS technology for positioning, and require the mobile phone application to remain open or in the background execution state to continuously track the user's location.

In addition to the location service initiated by the terminal, there are many needs in real life that must be initiated from the server side, for example, to find lost children, the elderly, or trapped people in disaster areas. Mobile phone services of this type of application are quite rare, due to the following reasons In addition to resource issues and no commercial value, the application must be activated in order to continue positioning and tracking, and the GPS signal is easily affected by terrain or weather and loses the signal. In addition, it is difficult for a person who has lost the ability to actively initiate a call for help to open the application to allow the server to locate it, so the actual help is not great.

In view of this, the present invention provides a tracking and positioning device and a tracking and positioning method, which can locate the user device when the user device does not actively send out a positioning request.

The tracking and positioning device of the present invention is suitable for tracking the location of a user device. The tracking and positioning device includes a transceiver, a storage medium and a processor. The storage medium stores multiple modules. The processor is coupled to the transmitter and the storage medium, and accesses and executes the modules. These modules include: a short message transceiver module and a traffic analysis module. The short message transceiver module transmits the senseless short message to the user device through the transceiver, and receives the user traffic corresponding to the senseless short message through the transceiver. The traffic analysis module generates location information of the user device based on the user traffic.

The tracking and positioning method of the present invention is suitable for tracking the location of a user device. The tracking and positioning method includes: transmitting a senseless short message to the user device, and receiving user traffic corresponding to the senseless short message; and generating user device information based on the user traffic Location information.

Based on the above, the present invention can track the user device by sending a senseless short message when the user device does not actively activate the positioning function or the user device does not support the global positioning system (GPS).

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

FIG. 1 illustrates a schematic diagram of a tracking and positioning device 10 according to an embodiment of the present invention. The tracking and positioning device 10 includes a processor 100, a storage medium 200 and a transceiver 300. The tracking and positioning device 10 is suitable for tracking the location of a user device, where the user device is, for example, a mobile station, an advanced mobile station (AMS), a server, a client, a desktop computer, a notebook computer, and a network. Computer, workstation, personal digital assistant (PDA), personal computer (PC), scanner, telephone device, mobile phone, pager, camera, TV, handheld game console, music device or wireless Sensors, etc., the present invention is not limited to this.

The processor 100 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessors, digital signal processors (DSP), and programmable Integrated circuit (application specific integrated circuit, ASIC), graphics processor (graphics processing unit, GPU) or other similar components or a combination of the above components. The processor 100 is coupled to the storage medium 200 and the transceiver 300, and can access and execute modules or various application programs stored in the storage medium 200.

The storage medium 200 is, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), or flash memory. , Hard disk drive (HDD), solid state drive (solid state drive, SSD) or similar components or a combination of the above components, which are used to store multiple modules or various applications that can be executed by the tracking and positioning device 10. In this embodiment, the storage medium 200 can store multiple modules including a short message transceiver module 210, a traffic analysis module 220, a geographic information module 230, and a monitoring module 240, the functions of which will be described later.

The transceiver 300 transmits downlink signals and receives uplink signals in a wireless or wired manner. The transceiver 300 may also perform operations such as low noise amplifying (LNA), impedance matching, frequency mixing, up-down conversion, filtering, amplification, and the like.

The tracking and positioning device 10 of the present invention can locate the user device to be tracked when the user of the user device loses behavior ability. For example, when a user of a user device is trapped, the tracking and positioning device 10 can obtain location information of the user device by sending a senseless short message to help search and rescue personnel grasp the location of the trapped person.

Specifically, when there is a need to track a user’s device, the short message transceiver module 210 of the tracking and positioning device 10 can transmit one of the short message services (short message service, SMS) through the transceiver 300: a senseless short message to the user Device and receive user traffic corresponding to the non-sense short message through the transceiver 300. The insensible short message is, for example, a type 0 (type 0) short message. When the SMS received by the user device is a type 0 SMS, the user device will not prompt the user of the user device that it has received the insensitivity SMS, and the user device will not store the insensitivity SMS to the user device’s In memory.

The short message transceiver module 210 can send a senseless short message to the user device in response to the operation of the operator of the tracking positioning device 10, and can also send the senseless short message to the user device according to a preset period. Periodic non-sense short messages can help the tracking and positioning device 10 draw a movement trajectory diagram of the tracked user device, thereby obtaining the movement trajectory information of the user of the user device.

After receiving the user traffic from the user device, the traffic analysis module 220 of the tracking and positioning device 10 can generate the location information of the user device according to the user traffic. Specifically, user traffic includes information such as an international mobile subscriber identity (IMSI), base station information, or time stamp corresponding to the user device. The traffic analysis module 220 first converts the international mobile subscriber identification code into a mobile subscriber ISDN number (MSISDN), and generates geographic information of the base station used by the user device based on the base station information. The geographic information of the station is, for example, the latitude and longitude of the base station or the address of the base station. Then, the geographic information module 230 of the tracking and positioning device 10 can calculate the location information of the user device (for example, the latitude and longitude or address of the user device) based on the geographic information, so as to achieve the effect of tracking the user device. In short, the tracking and positioning device 10 can calculate the location or range of the user device based on the geographic information of one or more base stations used by the user device.

Based on the mobile communication technology used by the user device, the base station information may include different patterns. For example, when the mobile communication technology used by the user device being tracked is the third generation of wireless mobile telecommunications technology (3G), the base station information may include location area code (LAC). ) Or base station number (cell ID). When the mobile communication technology used by the user device being tracked is the fourth generation of mobile phone mobile communication technology standards (4G), the base station information may include tracking area code (TAC) or Service area code (SAC).

The monitoring module 240 of the tracking and positioning device 10 has functions such as finding lost people, assisting trapped victims, or preventing monitoring objects from entering the warning zone.

For example, when the tracking and positioning device 10 obtains multiple location information of a user device of a lost population (or trapped victim) by periodically sending a senseless text message, the monitoring module 240 can use the location information and The time stamp in the user message returned by the user device is used to draw the movement track diagram of the user device. The monitoring module 240 can display the movement track diagram or real-time location information of the user device through the display device, thereby helping the police or family members to confirm the movement range of the lost population (or trapped victims).

For another example, when the tracking and positioning device 10 obtains location information of a user device of a monitored person by sending a senseless short message, the monitoring module 240 may generate an alert in response to the user device moving to a predetermined warning area. For example, if a child brings a user device to the riverside, the monitoring module 240 can send a warning message through the transceiver 300 in response to the riverside being classified as a pre-determined warning zone with danger (for example, by sending a warning including warning A short message of the message) to the monitoring personnel responsible for monitoring the pre-determined warning zone (for example: the police) or the related person of the citizen and child, reminding these personnel that the citizen and child may be in a dangerous area.

FIG. 2 shows a flow chart of a tracking and positioning method according to an embodiment of the present invention, wherein the tracking and positioning method can be implemented by the tracking and positioning device 10 shown in FIG. 1. The tracking location method is suitable for tracking the location of the user device. In step S21, the non-sense short message is transmitted to the user device, and the user service corresponding to the non-sense short message is received. In step S22, the location information of the user device is generated according to the user traffic.

In summary, the tracking and positioning method of the present invention can trigger the tracked user device to send back user traffic through a senseless short message, so as to calculate the location of the user device based on the user traffic. In this way, the user device can be tracked by the tracking and positioning device without actively enabling the positioning function, or even without supporting the GPS function. In addition, current mobile phones support the function of sending and receiving short messages. Even if the mobile communication technology continues to evolve, the present invention can still be applied to new generation smart phones. Since the present invention does not require the user of the user device to actively activate the positioning function, the present invention can achieve the effect of tracking disabled persons (for example: lost population, children, trapped households or demented elderly).

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the attached patent application.
