Description

Tracking positioning device and tracking positioning method

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

With the popularization of smart phone application services, various positioning-related services have brought people a more convenient life. Most of the positioning needs of these services are initiated by the terminal device. For example, when the user needs map navigation, searching for nearby restaurants, stores, and searching for nearby discounts, the user actively initiates the positioning function through the terminal device. Most of the above services use GPS technology for positioning, and the mobile phone application needs to be kept on or in the background execution state to continuously track the user's location.

In addition to the positioning service initiated by the terminal, there are many needs in real life that must be initiated from the server. For example, to find missing children, the elderly, or the people in the disaster-stricken areas. Mobile phone services for such applications are quite rare, for reasons other than In addition to information issues and no commercial value, the application must be activated to continue positioning and tracking, and the GPS signal is vulnerable to terrain or weather and loses its signal. In addition, it is difficult for someone who has lost the ability to initiate a request for help to open the application to allow the server to locate, so the actual help is not great.

In view of this, the present invention proposes a tracking and positioning device and a tracking and positioning method, which can locate a user device without actively issuing a positioning requirement.

The tracking and positioning device of the present invention is suitable for tracking the position 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 receiver and the storage medium, and accesses and executes the modules. The modules include: SMS transceiver module and traffic analysis module. The SMS transceiver module transmits the non-sensing SMS to the user device through the transceiver, and receives the user's message corresponding to the non-sensing SMS through the transceiver. The traffic analysis module generates the location information of the user device according to the user traffic.

The tracking and positioning method of the present invention is suitable for tracking the position of a user device. The tracking and positioning method includes: sending a non-sensing SMS to the user device, and receiving user traffic corresponding to the non-sensing SMS; and generating the user device according to the user traffic Location information.

Based on the above, the present invention can track the user device by sending a non-sensing SMS when the user device does not actively turn on 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 obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.

FIG. 1 is 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 position 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, a network Computers, workstations, personal digital assistants (PDAs), personal computers (PCs), scanners, telephone devices, mobile phones, pagers, cameras, TVs, handheld game consoles, music devices 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 microprocessor (microprocessor), digital signal processor (DSP), programmable Controller, application specific integrated circuit (ASIC), graphics processor (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), flash memory (flash memory) , A hard disk drive (HDD), a solid state drive (SSD), or a similar component or a combination of the above components, and is 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 may 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. Their functions 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 to be tracked loses the ability to act. For example, when the user of the user device is trapped, the tracking and positioning device 10 can obtain position information of the user device by sending a non-sensing SMS, to help search and rescue personnel to grasp the location of the trapped person.

Specifically, when there is a need to track a user's device, the short message sending and receiving module 210 of the tracking and positioning device 10 can transmit one of the short message service (SMS) short messages through the transceiver 300: a non-sensing short message to the user Device, and receive user traffic corresponding to the non-sensing SMS through the transceiver 300. Non-sensing text messages are, for example, type 0 (type 0) text messages. When the text message received by the user device is a type 0 text message, the user device does not prompt the user of the user device that it has received the non-sensing message, and the user device does not store the non-sensing message to the user device’s In memory.

The SMS transceiving module 210 can transmit the non-sensing SMS to the user device in response to the operation of the operator of the tracking and positioning device 10, or can send the non-sensing SMS to the user device according to a preset period. The periodic non-sensing SMS can help the tracking and positioning device 10 to draw the tracked movement trajectory of the 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, the user traffic includes information such as an international mobile subscriber identity (IMSI) corresponding to the user device, base station information, or time stamp. The traffic analysis module 220 first converts the international mobile subscriber identification code into a mobile subscriber ISDN number (MSISDN), and generates the geographic information of the base station used by the user device according to 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, longitude, or address where the user device is located) according to 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 different mobile communication technologies used by the user device, the base station information may include different appearances. For example, when the mobile communication technology used by the tracked user device is the third generation of wireless mobile telecommunications technology (3G), the base station information may include a location area code (LAC) ) Or base station number (cell ID). When the mobile communication technology used by the tracked user device is the fourth generation of mobile phone mobile communication technology standards (4G), the base station information may include a tracking area code (TAC) or Service area code (SAC).

The monitoring module 240 of the tracking and positioning device 10 has functions of searching for the lost population, assisting the trapped victims or preventing the monitoring object from entering the warning area.

For example, when the tracking and positioning device 10 obtains multiple location information of a user device of a lost population (or trapped disaster victims) by periodically sending a non-sensing SMS, the monitoring module 240 may use the location information and The time trace in the user traffic returned by the user device is used to draw the movement trajectory of the user device. The monitoring module 240 can display the movement trajectory map or real-time location information of the user device through the display device, thereby helping the police or family members to confirm the range of activities of the lost population (or trapped victims).

As another example, when the tracking and positioning device 10 obtains the location information of a user device of a monitored person by sending a non-sensing SMS, 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 carries a user device to the riverside, the monitoring module 240 may send a warning message through the transceiver 300 in response to the riverside being classified as a dangerous precautionary zone (for example, by sending a warning including Messages) to the monitoring personnel (eg police) who are responsible for monitoring the predetermined warning area or related persons of the children, reminding them that the children may be in a dangerous area.

FIG. 2 illustrates a flowchart of a tracking and positioning method according to an embodiment of the present invention, wherein the tracking and positioning method may be implemented by the tracking and positioning device 10 shown in FIG. 1. The tracking and positioning method is suitable for tracking the position of the user device. In step S21, the non-sensing SMS is sent to the user device, and the user message corresponding to the non-sensing SMS 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 return user traffic through a non-sense SMS, so as to calculate the location of the user device according to the user traffic. In this way, the user device can be tracked by the tracking and positioning device without actively turning on the positioning function or even supporting the GPS function. In addition, current mobile phones support the function of sending and receiving SMS. Even if the mobile communication technology continues to evolve, the present invention can still be applied to a new generation of smart phones. Since the present invention does not require the user of the user device to actively turn on the positioning function, the present invention can achieve the effect of tracking persons who have lost their ability to act (such as: lost population, children, trapped victims, or demented elderly).

Although the present invention has been disclosed as above with examples, it is not intended to limit the present invention. Any person 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 subject to the scope defined in the appended patent application.
