Description

{MOBILE TERMINAL LOSS PREVENTION SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a mobile terminal loss prevention technique, and more particularly, to a mobile terminal loss prevention system that can induce a call signal of a learned person and enable quick collection.

Recently, the use of mobile terminals such as smart phones and tablet PCs is exploding. Smartphones and tablet PCs can be said to be portable computers with most of the features that a personal computer can carry. They include a wide range of features such as e-mail transmission / confirmation, document editing, still video or movie recording, and mobile credit card payment from basic voice calls.

It has become more dependent on users because it has various functions, and it can be said that most modern people are always required to carry around.

However, the portability of such a multifunctional handset is very convenient and there is always a possibility of loss. As described above, since it is an essential device having a high dependence on life, the inconvenience caused by loss is also very large. Moreover, since it is an expensive device having various functions, the economic loss due to loss is also small.

Techniques for preventing the loss of a mobile terminal have been proposed so far, and a basic function thereof is to put the mobile terminal in a locked state when not in use. Such a lock state is released and available only when a password set by the user is input. Therefore, it also protects individual privacy and prevents unauthorized use of the mobile terminal by the acquirer.

Nevertheless, the rate at which recently lost mobile terminals are recovered is not very high. Because the mobile terminal is so expensive, it can not be recovered if the acquaintance has malice. In fact, many lost mobile terminals are exported overseas and used and traded as second hand phones.

What is more problematic is that even if the acquaintance is not malicious, it can not be recovered. When the user notices that the mobile terminal is lost, it is because there is no way to contact the user because most of the mobile terminals are in the locked state even if the acquirer is not malicious. When the time elapses in this state, the recovery rate becomes very low.

Therefore, there is a demand for a loss prevention system that is highly likely to recover lost mobile terminals.

Therefore, the acquirer can easily make a call with the user by sending a call signal by touch or the like.

2 is a block diagram illustrating a mobile terminal 1 applied to a mobile terminal loss prevention system according to a preferred embodiment of the present invention.

2, the mobile terminal 1 according to the present invention includes a main communication unit 11, a first short-range communication unit 13, a memory unit 14, a display unit 12, And a terminal control unit 15. The elements of the above-mentioned mobile terminal 1 are built in or supported in the case. In addition, the mobile terminal 1 typically has a function of the user interface so that the user can touch the icon displayed on the display unit 12. It is needless to say that the mobile terminal 1 according to the present invention may be provided with a physical input button 16 or a button other than the display unit 12. [

The main communication unit 11 provided in the mobile terminal 1 corresponds to a communication module for voice communication and data communication of a general portable telephone.

The first short range communication unit 13 may be, for example, a Bluetooth module or an RFID module.

The memory unit 14 may store an operating system or other programs for operating the system. The memory unit 14 also stores a program for driving the loss prevention operation of the present invention.

The mobile terminal 1 according to the present invention may include a speaker 17 and a microphone 18 for performing a voice call such as a general mobile phone or a mobile terminal and a microphone 18 for supplying power necessary for driving the mobile terminal 1 And a battery 19.

The terminal control unit 15 controls the operation of elements included in the mobile terminal 1, including the above-described components as a typical processor.

Also, although not shown here, the mobile terminal 1 may further include a camera, a GPS module, an acceleration sensor, and the like.

The mobile terminal 1 is basically capable of performing voice communication and data communication.

The user can set the call identification code to, for example, a telephone number of a family member, a friend or a colleague. If the call signal to be transmitted to the learner is a data call signal other than a voice call signal, it may be an ID corresponding thereto.

3 is a block diagram showing a loss prevention unit 2 applied to a mobile terminal loss prevention system according to a preferred embodiment of the present invention.

3, the loss prevention unit 2 applied to the mobile terminal loss prevention system of the present invention includes a unit control unit 21 and a second short range communication unit 22. [ The loss prevention unit 2 further includes an alarm unit 23, a timer 24, a battery 25, and a search key 27. The loss prevention unit 2 may further include a switch 26 for connecting or disconnecting the power source of the battery 25. This loss prevention unit 2 may have the appearance of a card or a tag.

The second short range communication unit 22 may be, for example, a Bluetooth module or an RFID module. The second short-range communication unit 22 is paired with the first short-range communication unit 13 of the mobile terminal 1 and is in a wireless connection state wirelessly connected.

The connection of the wireless communication is maintained within the communication range of the short-range wireless communication. Conversely, if the communication range is outside the range, the connection will be disconnected.

As shown in FIG. 4, when the wireless communication connection between the mobile terminal 1 and the loss prevention unit 2 is disconnected, the mobile terminal 1 displays a call signal transmission indication as described above. The call signaling indication may be a number indicating the set telephone number or an icon associated with it, which may be displayed in the form of a pop-up icon or a pop-up window. The mobile terminal 1 automatically transmits a call signal corresponding to the connected call identification code through the main communication unit 11 when the learner touches the call signal display (call display in FIG. 4).

As described above, the call signal transmission indication displayed on the display unit 12 of the mobile terminal 1 can be displayed even when it is in the power saving mode.

In addition, the pop-up window displayed in the communication disconnection state may further include a cancel icon in addition to the call icon, as shown in FIG. This cancellation icon can be used by the user to cancel the pop-up window if the communication is disconnected but not substantially lost.

Returning to the description of the loss prevention unit 2 again, the alarm unit 23 may be an element for making a sound or performing a vibration operation. The alarm unit 23 performs a notification operation under the control of the unit control unit 21 when the wireless communication connected to the mobile terminal 1 is disconnected so that the user can quickly recognize that the wireless communication connection with the mobile terminal 1 is disconnected Can be done.

In addition, the loss prevention unit 2 includes a timer 24 so as to reduce the consumption of the battery 25 by repeating the connection and disconnection with the mobile terminal 1 every time period set under the control of the unit control unit 21 . In this case, when the terminal control unit 15 of the mobile terminal 1 repeats a predetermined number of times when the connection is not established at the communication connection period, it can be determined in advance that the wireless communication is disconnected.

Also, the call signal display, which is preferably displayed in a pop-up window or the like, may be a phrase or an icon for guiding the input to the learner. In addition, call signaling indication can be made visible by flashing or periodic color or size change.

5A and 5B show examples of possible operation scenarios including a call signaling indication at the time of radio communication disconnection between the mobile terminal 1 and the loss prevention unit 2. [ This operation scenario may be implemented, for example, by a loss prevention program installed in the mobile terminal 1 and operating in the background.

For example, FIG. 5A is a basic scenario that typically induces call signaling when a communication is disconnected. When communication is disconnected, a pop-up window including a call signaling indication is displayed as shown in (1) of Fig. 5A. Then, after the acquirer touches the call icon to make a call (② in FIG. 5A) with the terminal corresponding to the call setup code set by the user, the lock enters the state as shown in (3) of FIG. Here, the locked state may be a locked state operated by the loss prevention program or a locked state operated by a program provided to the mobile terminal. It may be a locked state, preferably operated by a loss prevention program, because there may be a mobile terminal that is not normally locked. As shown in the figure, the locked state is switched to a screen for guiding the user to input a password. When the set password is input, it is switched to the password pattern set in the mobile terminal, or in the case of the mobile terminal in which the password pattern is not set, the main screen will be changed.

Such entry into the locked state can prevent leakage of personal information after a call.

5B illustrates a scenario in which a pop-up window including a call signaling display is displayed in a communication disconnection state, and then a cancel icon is touched. Similarly, if the communication is disconnected, a pop-up window is displayed as shown by (1) in Fig. 5B. At this time, when the cancel icon is touched, the lock state (② in FIG. 5B) is entered. Here, the locked state is also a screen operated by the loss prevention program. When the set password is input, it is switched to the set password pattern, or when the password pattern is not set, it is switched to the main screen. This is also to prevent the leakage of personal information. In the case where the revocation icon is touched, it may be by the user or by the acquaintance, but by allowing the lock state to be released by inputting the password by the loss prevention program, leakage of the personal information can be completely prevented .

A function that can be additionally included in the mobile terminal loss prevention system of the present invention is to find the mobile terminal 1 through the loss prevention unit 2. [ 1, when the seek key 27 provided in the loss prevention unit 2 is pressed, the mobile terminal 1 in the connected state performs the ring tone emission or vibration operation. This can be performed in the speaker 17 or the vibration element (not shown) under the control of the terminal control unit 15 according to the function included in the loss prevention program. This searching function enables the user to quickly locate the mobile terminal 1 with a simple operation through the loss prevention unit 2 possessed by the user without performing call origination using another mobile terminal as in the conventional method .

FIG. 6 is a flowchart illustrating an operation of a mobile terminal loss prevention system according to a preferred embodiment of the present invention. The operation shown in FIG. 6 shows a loss prevention operation in which a loss prevention program is executed in the background after a user sets a call identification code corresponding to a call signaling indication.

First, as in step S101, it is periodically checked whether the wireless communication with the loss prevention unit 2 is disconnected. If it is not in the disconnected state, step S101 is repeated again.

If it is the disconnected state, the process advances to step S102 to check whether the number of disconnected states is equal to or greater than a predetermined number of times. Here, the predetermined number of times may be one time or a plurality of times (for example, two times). The case where the mobile terminal 1 and the loss prevention unit 2 are always connected by short-range wireless communication such as Bluetooth. If the loss prevention unit 2 has two or more times, it may correspond to the case where the loss prevention unit 2 has the power saving mode. If the disconnection state is equal to or less than the predetermined number of times, the process returns to step S101.

If the disconnection state is equal to or larger than the predetermined number of times, the process proceeds to step S103 to display the call signal origination display on the display unit 12. [

In step S104, when there is an input (touch) signal of a call icon such as the touch input of the acquirer, the process proceeds to step S105 and a call signal is transmitted to the call identification code associated with the call signal transmission indication.

Thereafter, when the call is terminated in step S106, the process proceeds to step S107 to enter the locked state.

Otherwise, if there is an input (touch) signal of the cancel icon in step 104, the process directly proceeds to step S10 to enter the lock state.

Thereafter, as described with reference to FIGS. 5A and 5B, when the password set in the locked state represented by the loss prevention program is input, the screen is switched to the set password pattern screen, or when there is no set password pattern, the screen is switched to the main screen.

In the mobile terminal loss prevention system of the present invention, the call signal transmission indication is displayed immediately at the initial point of time when the acquirer learns the lost mobile terminal, so that quick communication with the user side can be performed and the possibility of collection is increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
