Referring to FIG. 1, according to one embodiment of the present invention, the position of the portable terminal 200 can be found by using one pager 100 in an indoor space of a home or a company, and in another embodiment of the present invention Accordingly, it is possible to locate the portable terminal 200 using the plurality of pagers 100, 101, 102, ....

A plurality of pagers (100, 101, 102, ...) can be placed at a desired position within the indoor space. It is preferable that the plurality of pagers 100, 101, 102, ... be placed at a position easily visible to the user or at a position where the user frequently stays. Also, the plurality of pagers 100, 101, 102, ... may be implemented as a unique device operating through its own battery.

Before or after arranging the plurality of pagers 100, 101, 102, ... in the indoor space, the user inputs information (for example, peculiar ID information of pagers, etc.) of each of the plurality of pagers 100, 101, 102, Can be registered in the portable terminal 200 and the information of the plurality of registered pagers 100, 101, 102, ... can be managed in the form of a list. Since the mobile terminal 200 is capable of transmitting and receiving signals to and from a plurality of pagers 100, 101, 102, ..., the present invention provides a plurality of pagers 100, 101, 102, It is possible to easily find the position of the mobile terminal 200 with respect to a wide area.

When a plurality of pagers 100, 101, 102, ... are arranged in a wide space, the user emits a terminal call signal through one of the plurality of pagers 100, 101, 102, The peripheral pagers 101, 102, ... other than one pager 100 receive the terminal call signal emitted from one pager 100 and repeat the received terminal call signal to the indoor space Can be developed. Accordingly, the present invention can develop the terminal call signal without a shadow area in a wide space, so that the position of the mobile terminal 200 can be found more easily and quickly.

A plurality of pagers (100, 101, 102, ...) may operate in an active mode and a low power mode to reduce the consumption of self-contained batteries. In addition, the portable terminal 200 may dynamically reduce or increase a scanning period for detecting a signal (e.g., a terminal call signal, a call area access signal) emitted from a pager in order to reduce battery (or power) . The description will be described later in more detail.

The mobile terminal 200 is a mobile communication device that ensures portability or mobility. For example, the mobile terminal 200 may be a Personal Communication System (PCS), a Global System for Mobile communication (GSM), a Personal Digital Cellular (PDC), a Personal Handyphone System (PHS), a Personal Digital Assistant (PDA) (WCDMA) -2000, Code Division Multiple Access (CDMA) -2000, W-CDMA (WCode Division Multiple Access), Wibro (Wireless Broadband Internet) terminals, smart phones, smart pads, Such as a smart watch or the like, or a wireless communication device based on any kind of handheld or wearable. In addition, the portable terminal 200 is not limited to the above-described examples.

Wireless communication such as NFC (Near Field Communication), Bluetooth, beacon, etc. may be performed between the pagers 100, 101, 102, ... and the mobile terminal 200, but is not limited thereto.

Hereinafter, only the pager 100 of one of the plurality of pagers 100, 101, 102, ... will be described in connection with the pager proposed in the present application. The same can also be applied to pagers 101, 102, ....

2 is a block diagram schematically illustrating a configuration of a pager according to an embodiment of the present invention;

Referring to FIG. 2, the pager 100 according to an embodiment of the present invention may include a terminal call signal emitting unit 110 and a controller 120.

The terminal call signal emitting unit 110 may emit a terminal call signal for a call of the mobile terminal based on a user input. Here, the pager 100 according to an exemplary embodiment of the present invention may include a first button unit 111, and may receive a user input for calling a portable terminal through the first button unit 111. [

The first button unit 111 may be a conceptual button including a physical button, a touch button, and the like.

When a user input is received through the first button unit 111, a terminal call signal generator (not shown) may generate a terminal call signal for calling the mobile terminal in the pager 100, May be emitted by the terminal call signal emitting unit 110.

Here, the terminal call signal emitting unit 110 may determine whether or not the position display intensity of the portable terminal 200 (to be described later) is higher than the predetermined value, based on whether or not the preset condition is satisfied (for example, whether user input is received plural times within a predetermined time) (Not shown) to the terminal calling signal generated by the terminal calling signal generating unit (not shown). Alternatively, if a terminal call signal generating unit (not shown) newly generates a terminal call signal considering a control signal, the terminal call signal emitting unit 110 may emit a terminal call signal considering a newly generated control signal have.

The control unit 120 may control the operation of the terminal call signal emitting unit 110. The control unit 120 includes a pager 100 such as a terminal call signal receiving unit 130, a paging area access signal emitting unit 140, an ID generating unit (not shown), and a terminal call signal generating unit (not shown) Lt; RTI ID = 0.0 > (e. G., ≪ / RTI >

If it is determined that the user input is received through the first button unit 111, the control unit 120 turns on the power of the terminal call signal emitting unit 110 for a preset time period so that the pager 100 operates in the active mode . Here, the predetermined time may be set by user input, for example, 5 seconds, 10 seconds, and the like.

Also, the controller 120 may turn off the power of the terminal call signal emitting unit 110 for a period of time other than a predetermined time (normal) to control the pager 100 to operate in a low power mode.

In other words, the control unit 120 can turn off the power of the terminal call signal emitting unit 110 so that the pager 100 normally operates in the low power mode. If the user operates the first button unit 111, When it is determined that the input has been received, the power of the terminal call signal emitting unit 110 can be controlled to be turned ON so that the first button unit 111 is operated in the active mode only for a predetermined time from the time when the first button unit 111 is pressed.

The pager 100 has a distinction ID so as to be distinguished from other pagers 101, 102, ... on the pager list of the mobile terminal 200 and the portable terminal 200 can list such a distinction ID. The distinction ID is the ID of the pager 100, which is distinguished from the IDs of the other pagers 101, 102, ..., in other words, the identification ID. The distinction ID may be randomly generated in the pager 100 via an ID generator (not shown) or may be generated by user input.

The pager 100 can receive the randomly generated distinction ID corresponding to the pager 100 by the ID generator (not shown), and if the assigned distinction ID exists in the area where the pager 100 can transmit / receive the terminal call signal If the neighboring pagers 101, 102, ... are identical to the neighboring pagers, it is possible to reset the distinction IDs at random.

At this time, when the pager 100 receives a collision signal indicating that the distinction ID is the same as the ID of the neighbor pagers 101, 102, ..., on the pager list of the portable terminal 200 from the portable terminal 200, Can be performed.

Specifically, when a plurality of pagers 100, 101, 102, ... operate within a close area, and some pagers among a plurality of pagers 100, 101, 102, ... use the same ID, A collision of signals may occur between some pagers. In order to prevent such conflict, the pager 100 may reset the distinct ID of the pager 100 itself based on the user input for the ID reset. The pager 100 according to one embodiment of the present invention may include a second button unit 112 and the reset of the distinguishing ID may be performed based on user input through the second button unit 112. [ The second button unit 112 may be a conceptual button including a physical button, a touch button, and the like. Based on the user input through the second button unit 112, the ID generator (not shown) may randomly generate an ID different from the previous ID. It is desirable that the configuration such as a code for distinguishing these IDs be set to have a probability that it is difficult for the same ID to be generated again at random generation.

The pager 100 may include the distinction ID in the terminal calling signal emitted from the terminal paging signal emitting unit 110 and emit it into the area where the terminal paging signal can be transmitted and received through the control unit 120. [ Alternatively, the pager 100 may release the Distinctive ID by including it in the paging area access signal emitted from the paging area access signal emitting unit 140, which will be described later.

The mobile terminal 200 can identify the pager 100 from a plurality of pagers 100, 101, 102, ... by giving the pager 100 a distinguishing ID.

Meanwhile, the pager 100 according to an embodiment of the present invention may include a terminal call signal receiving unit 130. The terminal call signal receiving unit 130 can receive a terminal call signal emitted from other peripheral pagers 101, 102, ....

For example, when there are a plurality of peripheral pagers 101, 102, ... in an area where pager 100 can transmit / receive a terminal paging signal, pager 100 is connected to a plurality of peripheral pagers 101, 102, After receiving the terminal call signal from some pagers through the terminal call signal receiving unit 130, the terminal call signal received from some pagers may be emitted through the terminal call signal emitting unit 110.

In another example, when there are a plurality of neighboring pagers 101, 102, ... in the area where the terminal call signal can be transmitted and received in the pager 100, the pager 100 transmits a plurality of neighbor pagers 101, 102, ... via the terminal call signal receiving unit 130 and transmits the terminal call signal received through the terminal call signal receiving unit 130 to the other of the plurality of peripheral pagers 101, It can be forwarded to some pagers.

In other words, when there are a plurality of pagers 100, 101, 102 in a predetermined area of the indoor space, the terminal call signals emitted from the first pager 100 are transmitted to the second pager 101 and the second pager 102 And each of the second pager 101 and the second pager 102 can repeatedly expand the terminal call signal received from the first pager 100 into the indoor space.

In this regard, the present application discloses that although the user only presses the first button of any one of the plurality of pagers 100, 101, 102, ... (e.g., the first pager 100) 102, ... each also emit the same terminal call signal as the terminal call signal emitted from the first pager 100. For example, the portable terminal 200 is not the callable area provided by the first pager 100 The position of the portable terminal 200 can be easily found even if it exists in the callable area provided by the third pager 102. [ Here, the callable area provided by the first pager 100 may mean a range of an area where a terminal call signal can be transmitted.

Therefore, according to the plurality of pagers 100, 101, 102, ..., the calling signal can be spread evenly within a wide indoor space without a shadow area.

When the user inputs a plurality of times through the first button unit 111 within a predetermined period of time, the controller 120 determines that the position display intensity of the portable terminal 200 is low, A control signal for increasing the position display intensity or changing the position indicating means (configuration) of the portable terminal 200 may be included in the terminal call signal emitted from the terminal call signal emitting unit 110. [ Accordingly, as described above, the terminal call signal emitting unit 110 adds a control signal to the terminal call signal generated through the terminal call signal generating unit (not shown) and emits the control signal to the terminal call signal generating unit May emit a terminal call signal considering the newly generated control signal.

Here, the position indicating means may mean sound, light, vibration, etc. of the portable terminal 200. For example, the sound can be displayed through a speaker included in the portable terminal 200, and the light can be displayed through a light source (a light emitting element such as an LED) included in the portable terminal 200, . ≪ / RTI > Further, the position display intensity may be set by at least one of a sound pattern, a light pattern, and a vibration pattern. That is, the position expression intensity may be expressed by a combination of a sound (e.g., a ring tone, a buzzer sound, a sound pre-recorded by the user, etc.), light (e.g., illumination light of the portable terminal 200, Can be set by changing the values such as the intensity, the magnitude, the generation period, etc. in a single manner or in combination.

Thus, increasing the position display intensity of the portable terminal 200 may mean simply increasing the size of the sound, increasing the intensity of the vibration, or changing the brightness intensity of the light, for example. However, the present invention is not limited to this. As another example, it may be possible to allow the user who is looking for the portable terminal 200 to easily recognize the position of the portable terminal 200 by giving a variation to the variation, thereby enhancing the position expression intensity. For example, it may be determined that periodically blinking light having the brightness of the same a has higher position display intensity than that of constantly and continuously displaying light having a brightness of a.

For example, if the sound volume of the portable terminal 200 is preset to a volume level of one level among the volume levels of all 10 levels, the portable terminal 200 receiving the terminal call signal emitted through the pager 100 ) Can generate sound at the volume level of one stage. At this time, although the sound is generated from the portable terminal 200, the user may not be able to find the position of the portable terminal 200 at once because the sound is too small. In this case, the user can input a plurality of user inputs through the first button unit 111 of the pager 100. At this time, the pager 100 can set the user input through the first button unit 111 It is possible to confirm whether or not a predetermined number of times have been received within the time. If the user input is received a predetermined number of times within the preset time, the pager 100 determines that the position display intensity of the portable terminal 200 is low and sets the volume magnitude of the first step to 3 Step, step 5, step 7, step 10, etc., the control signal may be included in the terminal call signal and released. In this case, the control signal for increasing the position display intensity may be a control signal for gradually increasing the volume level step by step according to the number of user inputs, such as 1 step? 3 step? 5 step? 7 step? 10 step, May be a control signal that increases from the first stage to the third stage or from the first stage to the seventh stage. In this way, the pager 100 can make the position display intensity of the portable terminal 200 vary with a variation through the control signal, so that the user can easily recognize the position of the portable terminal 200.

In addition, the controller 120 may control the first position indicating means of the portable terminal 200 in response to the terminal call signal emitted from the pager 100, When the user input is received a plurality of times, a control signal for changing the mobile terminal 200 to operate as the second position indicating means in the first position displaying means is transmitted to the terminal calling signal emitted through the terminal calling signal emitting section 110 Can be included.

Here, the first position indicating means and the second position indicating means may mean simply one of sound, light and vibration, or a combination of two or more of sound, light and vibration.

For example, in response to the terminal calling signal emitted from the pager 100, the portable terminal 200 operates as the first position indicating means that the vibration operates at four levels of vibration intensity of 10 levels of vibration intensity, It is possible to operate with three levels of brightness of the brightness of the display device. If the user does not find the portable terminal 200 and then presses the first button 111 a plurality of times, the controller 120 determines that the portable terminal 200 operates as the second position indicating means in the first position indicating means 200 In the terminal call signal, the control signal changing the vibration to operate at a vibration intensity of nine levels, the light brightness to operate at ten levels of brightness, and the sound to operate at six levels of ten levels) (200).

Meanwhile, the pager 100 according to an embodiment of the present invention may include a paging area access signal emitting unit 140.

The paging area access signal emitting unit 140 determines that the portable terminal 200 has entered the area where the terminal pager signal can be transmitted and received (in other words, within the pager area provided by the pager 100) It can periodically emit a paging area access signal to inform. At this time, the portable terminal 200 periodically performs scanning to detect a signal (e.g., a terminal call signal or a call area access signal) emitted from the pager 100, The signal from the pager 100 including the terminal call signal is detected in a shorter period of time, and the signal emitted from the pager 100 during scanning If the paging area access signal is not detected, it is possible to increase the scanning period so that the signal emitted from the pager 100 including the terminal paging signal is detected in a longer period. As described above, the mobile terminal 200 can dynamically change the scanning period for detecting a signal (for example, a terminal call signal or a paging area access signal) emitted from the pager 100 according to a situation, thereby reducing unnecessary power consumption have. A more detailed description can be more easily understood with reference to FIGS. 3 and 4, which will be described later.

FIG. 3 is a flow diagram that schematically illustrates the operation of pager 100 in accordance with one embodiment of the present disclosure.

Referring to FIG. 3, in step S301, the pager 100 may periodically emit a paging area access signal to inform that the portable terminal 200 is entering the callable area provided by the pager 100. [ At this time, the pager 100 can, for example, emit a paging area access signal at a period that does not affect the battery consumption of the pager 100 itself. The mobile terminal 200 may transmit a signal (for example, a terminal call signal or a paging area access signal) from the pager 100, depending on whether the paging area access signal emitted from the pager 100 is received by the mobile terminal 200 Signal) can be changed by changing the setting of the scanning period.

 Next, in step S302, the pager 100 can determine whether the first button part 111 has been pressed (in other words, whether user input through the first button part 111 has been received).

If the first button unit 111 has not been pressed (S302-N), the pager 100 can return to the state before performing step S301.

On the other hand, when the first button unit 111 is pushed (S302-Y), the pager 100 can determine whether a user input through the first button unit 111 has been received a plurality of times within a predetermined time S303).

If the user input is received through the first button unit 111 a plurality of times within a predetermined time in step S303 (S303-Y), the pager 100 transmits the user input through the terminal call signal generator (not shown) The terminal call signal including the control signal for increasing the position display intensity of the mobile terminal 200 or changing the position display means can be generated (S304). Alternatively, in step S304, the pager 100 may add a control signal to the terminal call signal generated through the terminal call signal generator (not shown). Since the above description has been described in detail above, the following description will be omitted.

When the user input through the first button unit 111 is not received a plurality of times within a predetermined time in step S303 (S303-N), the pager 100 determines, based on the user input to the first button unit 111, The generated terminal call signal can be released through the terminal call signal emitting unit 110 (S305).

After step S304, in step S305, the pager 100 releases a terminal call signal including a control signal newly generated by a terminal call signal generator (not shown) through the terminal call signal emitting unit 110, A signal to which the control signal is added to the paging signal can be emitted through the terminal paging signal emitting unit 110.

4 is a flowchart schematically illustrating an operation of a portable terminal that is called through a pager according to an embodiment of the present invention.

4 is a flowchart for explaining a low power operation of the portable terminal 200. Referring to FIG. 4, steps S401 and S402 are performed when the portable terminal 200 is located outside the callable area provided by the pager 100 And steps S403 to S406 show operations performed when the portable terminal 200 is within the callable area provided by the pager 100. [

In step S401, the mobile terminal 200 may set a scanning period for detecting (detecting) a signal (e.g., a terminal calling signal or a paging area access signal) emitted from the pager 100 to a T1 period. In step S401, the portable terminal 200 periodically performs a scanning operation to detect a paging area access signal emitted from the pager 100 at a period of T1.

Next, in step S402, the mobile terminal 200 can determine whether a paging area access signal has been found.

If it is determined that the paging area access signal is not found (S402-N), it is determined that the pager 100 is not present near the portable terminal 200 and the portable terminal 200 determines that the state before the step S401 . When the mobile terminal 200 does not scan the paging area access signal for a predetermined time and finds it, the mobile terminal 200 determines that the pager 100 is not located near the pager 100, Can be increased more than T1, thereby saving the battery.

If it is determined that the paging area access signal is found (S402-Y), it is determined that the pager 100 is present near the portable terminal 200, and the portable terminal 200 receives the signal emitted from the pager 100 The scanning period for sensing can be set to T2 period. At this time, the T2 period may be shorter than the T1 period. In other words, if the paging area access signal is found, the mobile terminal 200 may detect the terminal paging signal emitted from the nearby pager 100 by setting the scanning period shorter than the T1 period so as to detect it frequently. That is, in step S403, the mobile terminal 200 may periodically perform a scanning operation to detect the terminal paging signal emitted from the pager 100 in a period of T2.

Next, in step S404, the mobile terminal 200 can determine whether or not the terminal call signal has been found.

As a result of the determination, if the terminal calling signal is found (S404-Y), the portable terminal 200 can control the position indicating means in response to the terminal calling signal received from the pager 100 (S405). At this time, the portable terminal 200 can raise the position expression intensity or change the position expression means based on the terminal call signal received from the pager 100. [ Examples of increasing the position display intensity or changing the position display means have been described in detail above, and therefore will not be described below.

On the other hand, if it is determined in step S404 that the terminal call signal is not found (S404-N), the mobile terminal 200 can determine whether a paging area access signal is found (S406).

If the paging area access signal is found in step S406 (S406-Y), the mobile terminal 200 can return to the state before performing step S403. If the paging area access signal is not found in step S406 (S406-N), the mobile terminal 200 can return to the state before performing step S401.

As described above, the mobile terminal 200 can reduce unnecessary power consumption by setting different scanning periods in and out of the callable area provided by the pager 100.

Briefly, the pager 100 can receive a user input for a call of the mobile terminal 200 through the first button unit 111. In addition, the pager 100 may receive a user input for resetting the ID through the second button unit 112. The status display unit 113 is a display unit that indicates the operation status of the pager 100 and can emit a light source such as an LED when the pager 100 is in operation (or when a user input is received). In addition, the rear surface of the pager 100 may be provided with an attachment pad, a magnet 114, and the like, for example, so that the pager 100 can be easily disposed at a desired position by the user.

5 (c) shows a pager 100 'according to another embodiment of the present invention, wherein most of the configurations are the same as those shown in Figs. 5 (a) and 5 (b) 'May be slightly different. That is, the back surface of the pager 100 'according to another embodiment of the present disclosure may be in the form of an outlet plug 115, for example. Thus, a user can plug a pager 100 'according to another embodiment of the present invention into an outlet and place it in an interior space through which the battery of the pager 100' can be charged. 5, the pagers 100 and 100 'according to an embodiment of the present invention may include a built-in battery unit (not shown). The pagers 100 and 100 'may be powered by a battery unit (not shown).

In the description with reference to FIG. 5, the position, shape, and the like of each structure are one example for explaining the present invention, but the present invention is not limited thereto. 5, the terminal call signal emitting unit 110, the control unit 120, the terminal call signal receiving unit 130, the paging area access signal emitting unit 140, the ID generating unit (not shown) And a terminal call signal generator (not shown) may be provided in the pager of FIG.

Hereinafter, the operation flow of the present invention will be briefly described based on the details described above.

6 is a schematic operational flow diagram of a method for calling via a pager in accordance with one embodiment of the present application.

The calling method of the pager shown in Fig. 6 can be performed by the pagers 100 and 100 'described above. Accordingly, the contents described with respect to the pagers 100 and 100 'may be similarly applied to FIG. 6, even if omitted below.

6, in step S610, the pager 100 may receive a user input for calling the portable terminal 200 through the first button unit 111. [

Next, in step S620, the control unit 120 can control the operation of the terminal call signal emitting unit 110 based on the user input received in step S610.

Here, if it is determined that the user input is received, the control unit 120 may turn on the power of the terminal call signal emitting unit 110 for a predetermined period of time to control the pager 100 to operate in the active mode, The power of the terminal call signal emitting unit 110 may be turned off for a period of time other than the set time to control the pager 100 to operate in the low power mode.

In addition, the control unit 120 may assign the distinction ID to the portable terminal 200 so as to be distinguished from other pagers on the pager list of the portable terminal

When there are a plurality of peripheral pagers in the area where the terminal call signal can be transmitted from the pager 100, the control unit 120 receives the terminal call signal from a part of the plurality of peripheral pagers, To another part of the surrounding pager.

If the distinction ID is randomly generated corresponding to itself and the distinction ID is the same as the neighbor ID assigned to the neighbor pagers existing in the area where the terminal call signal can be transmitted and received in the pager 100 , It is possible to reset the distinction ID at random. At this time, if the mobile terminal 200 receives a collision signal indicating that the distinction ID is the same as the ID of the neighbor pager on the pager list of the portable terminal 200, the control unit 120 can perform the resetting of the distinction ID. Here, the resetting of the distinguishing ID can be made based on the user input through the second button portion 112.

When the user input is received a plurality of times within a predetermined time, the control unit 120 determines that the position display intensity of the portable terminal 200 is low and increases the position display intensity or changes the position display means. May be included in the released terminal call signal. Here, the position display intensity may be set by at least one of a sound pattern, a light pattern, and a vibration pattern.

In addition, when the user input is received a plurality of times within a predetermined time after the first position indicating means of the portable terminal 200 operates in response to the terminal calling signal emitted from the pager 100 , The mobile terminal 200 may include in the emitted terminal call signal a control signal that changes the first position indicating means to operate as the second position indicating means.

The control unit 120 also transmits a paging area access signal for informing that the portable terminal 200 is entering the area where the terminal paging signal can be transmitted from the pager 100 through the paging area access signal emitting unit 140 It can be released periodically. At this time, the mobile terminal 200 periodically performs scanning to detect a signal (e.g., a terminal call signal or a call area access signal) emitted from the pager 100, When a paging area access signal is detected as a signal to be emitted, the scanning period is reduced so that a signal emitted from the pager 100 including the terminal paging signal is detected in a shorter period, If the paging area access signal is not detected as the signal, the scanning period may be increased so that the signal emitted from the pager 100 including the paging signal may be detected in a longer period. Accordingly, the portable terminal 200 can dynamically control the scanning period, thereby reducing unnecessary power consumption.

In case of scanning the paging area access signal, it is possible to reduce the scanning period of the paging area access signal or switch to the scanning mode for receiving the terminal paging signal. If the paging area access signal can not be scanned for a predetermined time, The signal scanning period can be increased.

Next, in step S630, based on the control in step S620, the terminal paging signal for calling the portable terminal 200 can be emitted through the terminal paging signal emitting part 110. [

In the above description, steps S610 to S630 may be further divided into additional steps or combined into fewer steps, according to embodiments of the present disclosure. Also, some of the steps may be omitted as necessary, and the order between the steps may be changed.
