In such a case, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state are protected by the second body 205. Further, even if the camera 121 of the second body 205 is not provided separately, the camera 121 of the first body is rotatably formed to be able to shoot up to the shooting direction of the camera 121 of the second body. It may be.

The terminal 100 illustrated in FIGS. 1 to 3 may be operated in a communication system capable of transmitting data through a frame or packet, including a wired / wireless communication system and a satellite-based communication system. It can be configured to.

Next, a communication system capable of operating a terminal according to the present invention will be described with reference to FIG. 4.

The communication system may use different air interfaces and / or physical layers. For example, a radio interface usable by a communication system may include frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (Code Division). Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE)), Global System for Mobile Communications (GSM), etc. May be included. Hereinafter, for convenience of description, description will be made based on the case of CDMA. However, it is a matter of course that the present invention is applicable to all communication systems including the CDMA wireless communication system.

As shown in FIG. 4, the CDMA wireless communication system includes a plurality of terminals 100, a plurality of base stations (BS) 270, and base station controllers (BSCs) 275. ), And a mobile switching center (MSC) 280. The MSC 280 is configured to be connected to a public switched telephone network (PSTN) 290 and is also configured to be connected to BSCs 275. The BSCs 275 may be coupled to the BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Thus, a plurality of BSCs 275 may be included in the system shown in FIG.

Each BS 270 may include at least one sector, and each sector may include an omnidirectional antenna or an antenna pointing in a radial direction from BS 270. Each sector may include two or more antennas of various types. Each BS 270 may be configured to support a plurality of frequency assignments, each of which has a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sectors and frequency assignments may be called a CDMA channel. BS 270 may be referred to as a Base Station Transceiver Subsystem ('BTSs'). In this case, the word "base station" may be called the sum of one BSC 275 and at least one BS 270. The base station may also indicate “cell site”. Each of the plurality of sectors for a particular BS 270 may be called a plurality of cell sites.

As shown in FIG. 4, a broadcasting transmitter (BT) 295 transmits a broadcast signal to terminals 100 operating in the system. The broadcast module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT 295.

In addition, FIG. 4 illustrates multiple satellite positioning systems (GPS) satellites 300. The satellites 300 help to locate the at least one terminal of the plurality of terminals 100. Although two satellites are shown in FIG. 4, useful location information may be obtained by two or less or more satellites. The GPS module 115 shown in FIG. 1 cooperates with the satellites 300 to obtain desired location information. Here, the location can be tracked using all the techniques that can track the location, not just the GPS tracking technology. At least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

During typical operation of a wireless communication system, BS 270 receives a reverse link signal from various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by a particular base station 270 is processed within by the particular base station 270. The data generated as a result of the processing is transmitted to the connected BSC 275. BSC 275 provides call resource allocation and mobility remote control functionality, including the organization of soft handoffs between base stations 270. The BSC 275 transmits the received data to the MSC 280, and the MSC 280 provides an additional transmission service for the connection with the PSTN 290. Similarly, PSTN 290 is coupled to MSC 280, MSC 280 is coupled to BSCs 275, and BSCs 275 are BS 270 to transmit forward link signals to terminals 100. Control them.

Now, a method of remotely controlling the mobile terminal 100 according to the present invention will be described.

5 is a flowchart illustrating a remote control method of the mobile terminal 100 according to an embodiment of the present invention.

Referring to this figure, in order to remote control, the portable terminal 100 must set conditions related to remote control (S10). The setting may include determining a condition for the first time or changing a previously determined condition. The determined condition is stored in the memory 160.

The set condition is meaningful only when there is a call connection request. Therefore, the controller 180 determines whether a call connection request is received. The call connection request is received through a mobile communication network or an Internet Protocol (IP) based Internet network. In an IP-based Internet network, a call connection request may be received in the form of an Internet Multimedia Subsystem (IMS). If there is no call connection request, the controller 180 checks again whether the call connection request is received while maintaining the standby state (S20).

In a state in which a call connection request is received, the condition determination unit 182 (see FIG. 1) of the controller 180 checks whether a condition is met or met as set. If the condition is not satisfied, the controller 180 will end the remote control method (S30). The above conditions will be described later with reference to FIG. 8.

If the condition is satisfied, the controller 180 allows the mobile terminal 100 to enter a remote control mode in which a call connection is made by the call connection request and is in a remote controllable state (S40). The notification unit 183 (refer to FIG. 1) of the controller 180 is a person who has a call connected party (a person having another terminal or a landline phone connected to the mobile terminal 100, and hereinafter referred to as an accessor). A short message can be used to notify the remote control mode entry.

The mobile terminal 100 operating in the remote control mode receives a function control signal from an accessor (S50). To this end, the guide unit 184 (see FIG. 1) of the controller 180 may guide a selectable function control signal to the accessor. The function control signal may have at least one of a form of dual tone multi frequency (DTMF), a form of packet data, a form of a short message, and a form of voice data.

In response to the above function control signal, the controller 180 causes the mobile terminal 100 to execute a remote control function (S60). In the present specification, the remote control function refers to a function executed in the mobile terminal 100 as it is controlled remotely through a mobile communication network, etc., rather than a direct operation of the operation unit 130 of the mobile terminal 100.

The remote control function may include, for example, an alarm control function, a data management function, a status notification function, a remote monitoring function, an induction function, a guidance function, and the like. These will be described later with reference to FIGS. 10 to 17.

6 is a flowchart illustrating a remote control method further including an authentication step as another embodiment of the embodiment of FIG. 5.

In this figure, condition setting (S110), call connection request reception determination (S120), condition satisfaction determination (S130), and entry into the remote control mode (S140) are the same as the corresponding steps of the foregoing embodiment, respectively.

When entering the remote control mode, the controller 180 requests an access key for an authentication key (S150).

If the authentication key is not received from the counterpart despite the request, the counterpart is a person having legitimate access to the mobile terminal 100 (a person representing a certain act for the benefit of the true owner or owner of the mobile terminal 100). It is likely that this is not the case (hereinafter referred to as 'owner'). In this case, the controller 180 ends the remote control process (S160).

The authentication key is normally received, and the authentication key determination unit 185 (see FIG. 1) of the controller 180 determines whether the authentication key set in the memory 160 and the received authentication key are the same (S170). If the two do not match, the controller 180 initializes the received authentication key so that the accessor can input the authentication key again. In this case, the controller 180 may transmit a hint related to the authentication key to the accessor. If there is a mismatch over the set number of times, the accessor determines that the owner is not the owner, and the controller 180 can output a response stored in the memory 160 or release the call connection.

If both are the same, the controller 180 executes the step of receiving the function control signal (S180) and the step of executing the remote control function accordingly (S190). The authentication key will be described later with reference to FIG. 9.

Unlike the above, the authentication step (S150 to S170) may be made after the step (S180) of receiving the function control signal from the accessor.

FIG. 7 is a flowchart of another embodiment of the embodiment of FIG. 5 in which the remote control function is executed a plurality of times.

Also in this embodiment, condition setting (S210), call connection request reception determination (S220), condition satisfaction determination (S230), and entering the remote control mode (S240) are the same as the corresponding steps of the previous embodiment, respectively. Do.

After entering the remote control mode, the controller 180 determines whether a first function control signal is received (S250). When the first function control signal is received, the controller 180 causes the first control remote control function to be executed in response (S260).

If the call connection state continues even after the first remote control function is executed, the guide unit 184 guides the second function control signal to the accessor (S270). If the second function control signal is not received, the guide unit 184 guides again a set number of times (S275).

When the second function control signal is received, the controller 180 causes the second remote control function to be executed (S280). This second remote control function may be a different function from the first remote control function. As a result, the accessor can further enhance the level of remote control over the portable terminal 100 over time.

For example, if the first attempt was made to determine the location of the mobile terminal 100 by maximizing the ringing sound of the mobile terminal 100, in the second, the mobile terminal 100 was more actively activated by activating the camera 121. You might want to know where it is.

If the call connection is still maintained, the steps S270 to S280 for causing the above second remote control function to be executed are similarly repeated. This allows the Nth (N is an integer of 3 or more) remote control function to be executed (S290).

8 is a perspective view of a portable terminal 100 for explaining one type of condition for remote control according to an embodiment of the present invention.

As illustrated in the figure, an accessor may transmit an authentication code together while requesting a call connection to the mobile terminal 100. In the caller's number (010-1234-5678- # 9546) displayed on the display unit 151, '# 9546 (151a)' is an authentication code for confirming the access right to the mobile terminal (100).

As the call connection request is made with the authentication code as described above, there is an advantage that the call connection request is accepted and the above conditions are satisfied and the control mode can be quickly entered. The authentication code is compared with the authentication code stored in the memory 160 by the condition determining unit 182, and it is determined whether the two match.

Alternatively, the condition determiner 182 may determine whether the number or time of the call connection request of the accessor reaches the set condition. To this end, the condition determination unit 182 detects the incoming ring to determine the number or time of the call connection request.

For example, if the accessor continues the call connection request until the incoming ring rings 10 times, the controller 180 determines that the condition is satisfied and allows the mobile terminal 100 to enter the remote control mode.

Unlike the above, if the same caller (accessor) number is received as many times as the set number stored in the memory 160, the condition determination unit 182 determines that the condition is satisfied at the time of the call connection request corresponding to the set number of times. Can be. Furthermore, it may be recognized that the condition is satisfied even when receiving the preset caller number stored in the memory 160.

In addition, even when a short message including an authentication code is received, the condition determination unit 182 may determine that the above condition is satisfied. If the call connection request is made to the same number as the number that transmitted the above message after the short message is first received, the controller 180 may cause the mobile terminal 100 to enter the remote control mode. On the other hand, if the above short message is received while receiving a call connection request from the accessor, the remote control mode may be similarly entered.

9 is a perspective view illustrating one input form of an authentication key transmitted to the mobile terminal 100 according to an embodiment of the present invention.

Referring to this figure, an accessor inputs an authentication key to be transmitted to the owner's portable terminal 100 through another portable terminal 100 '. The authentication key may be a pattern formed to be input through the display unit 151 'of the mobile terminal 100'. In this case, the display unit 151 ′ is a touch screen capable of touch input, and the pattern is a pattern by touch input. As illustrated, the touch pattern may be a spiral pattern or a pattern obtained by touching a plurality of points to form a predetermined shape while being spaced apart from each other.

Alternatively, the authentication key may be any one of numbers, letters, and symbols or a combination of at least two of them. Normally, numeric input will be easy.

The authentication key may be biometric information. Biometric information that can be distinguished from others may include, for example, a fingerprint, an iris, a face, a voice, and the like. To this end, the portable terminal 100 ′ may be equipped with at least one sensor for detecting the above biometric information.

Unlike the above, a specific operation of the accessor may be recognized through the camera of the portable terminal 100 'so that the operation may be an authentication key.

10 to 17, examples of the remote control function will now be described.

10 is a perspective view illustrating an alarm adjusting function of the portable terminal 100 according to an embodiment of the present invention.

The alarm control function is a function of changing a method of notifying reception of a call connection request to the mobile terminal 100.

The alarm function may include, for example, a function of notifying an incoming state of the mobile terminal 100 by ringing, vibrating, or activating the flash 250 (see FIG. 3), or by allowing an accessor to determine the location of the mobile terminal 100. It can also be understood. This is realized through the voice output module 152, the alarm unit 153, and the like of the output unit 150.

The alarm adjustment function is a function that enables to adjust or change the alarm function (method) of the mobile terminal 100 which is preset and stored in the memory 160 according to specific needs.

As an example of the alarm control function, it is possible to make the ringtone be louder than the preset volume in the ringtone mode of the incoming alarm mode according to the call request, and may be maximized. The volume may be gradually increased or converted to a constant value at one time. On the contrary, if the space in which the portable terminal 100 is placed is a space requiring quietness, it may be changed to the silent mode in which the bell sound is not emitted.

Referring to FIG. 10, in relation to the type of the bell sound, another ring sound may be output instead of a preset bell sound. For example, if a bell sound is output using a comment such as “I'm here, please come find me”, etc., it will be more in line with the intention and specific situation of the accessor looking for the mobile terminal 100.

If the incoming call mode is set to the vibration mode, it is also possible to maximize the intensity of the vibration or to switch the vibration to the bell sound as described above. You can also enable the ringing sound while activating the vibration.

During the output of such ring sounds and / or vibrations, flash 250 may also be activated together. The flash 250 may be operated to be continuously activated or intermittently activated. It is also possible to activate the flash 250 alone without outputting a ringing sound or the like.

11 is a conceptual diagram illustrating a data management function of the mobile terminal 100 according to an embodiment of the present invention.

Although it is not possible to physically access the portable terminal 100 at once, there may be a case where utilization of data stored therein is required. In addition, if the portable terminal 100 is lost, there may be a concern that it is impossible to leak or retrieve data stored therein.

The data management function allows the operation of data related to the mobile terminal 100 to be made remotely so that the above needs or concerns are solved to a considerable extent.

Referring to FIG. 11, the controller 180 allows data stored in the mobile terminal 100 to be transmitted to a base station or a backup server 281 interoperating with an MSC 280 (see FIG. 4) in particular due to execution of a data management function. can do. The data may be transmitted through the mobile communication module 112 or the wireless internet module 113.

During the transmission of the data, a function other than the data transmission may be switched to a locked state so that the person who is in the position where the portable terminal 100 is to be found or who has discovered or acquired (hereinafter referred to as an 'acquirer') does not interfere with it. Can be. If necessary, it may be necessary to unlock partially or entirely. The lock state can be set / released regardless of data transfer.

As shown in the drawing of the display unit 151, the image for inferring data transmission may not be output, and only a normal background screen may be output.

After the transmission of the data is completed, the mobile terminal 100 may be initialized. In this case, even if the portable terminal 100 is not returned to the owner, it is possible to prevent a situation in which the owner's information is leaked.

The controller 180 can block the supply of power by the power supply unit 190 in order to secure power required for data management and the like. If a request for connection of a call from an owner is received, it will be desirable for the call between the owner and the acquirer to be disconnected from the power source.

Alternatively, a second power supply other than the power supply 190 may be additionally provided in the portable terminal 100, which is operated only upon request for connection of a call from the owner and is otherwise controlled. The second power supply unit may be mounted on a circuit board or the like so as not to be exposed to the outside and positioned inside the portable terminal 100, and may be periodically charged by the power supply unit 190. If the second power supply is operated, the difficulty due to lack of power in the data backup or the like can be improved.

12 is a conceptual diagram illustrating another example of a data management function of the mobile terminal 100 according to an embodiment of the present invention.

The mobile terminal 100 may transmit data, which is stored in the memory 160 or currently received, to the portable terminal 100 ′ of the accessor. This allows an authorized accessor to the mobile terminal 100 to use the information stored in the mobile terminal 100 remotely through another mobile terminal 100 '.

Information stored in the mobile terminal 100 may include a phone book, a stored or received short message, a missed call list, a voice mail, a visual voice mail, a web favorite list, a memo, a schedule, and a content. There may be a file (picture file, image file, video file, MP3 file, etc.), a broadcast schedule, broadcast reservation recording information, and the like.

Referring to FIG. 12, broadcast information transmitted from the broadcast transmitter 295 and received by the mobile terminal 100 may be transmitted to the portable terminal 100 ′ of the accessor by a data management function. At the same time that the mobile terminal 100 receives it, real-time transmission may be performed to the mobile terminal 100 '. Accordingly, even if the portable terminal 100 'does not have a broadcast receiving module, an accessor can watch a broadcast using the portable terminal 100 provided with the broadcast receiving module 111.

In addition to transmitting data to the mobile terminal 100 ', the mobile terminal 100 may change and store data by an operation of an accessor to the mobile terminal 100'. For example, the accessor may input a name and phone number of a new counterpart into the phone book of the mobile terminal 100 using the mobile terminal 100 '.

Even in the case of the messenger program using the short message service of the portable terminal 100, the user's state can be changed. This corresponds to the situation of the owner who does not currently have the portable terminal 100.

13 is a perspective view illustrating a status notification function of the mobile terminal 100 according to an embodiment of the present invention.

As shown in FIG. 13, the status notification function is a function for notifying the learner that the mobile terminal 100 is a lost terminal.

Such a function may be achieved through the output unit 150 of the mobile terminal 100.

The voice output module 152 may output a message indicating that the mobile terminal 100 is a lost terminal. The comment may be output at predetermined time intervals or may be output when the sensing unit 140 detects an operation on the portable terminal 100.

When the operation of the portable terminal 100 is detected, the portable terminal 100 is already acquired by the learner, so it may be desirable to make the output of the announcement more intensively. The comment may include the owner's address or his contact phone number.

Through the display unit 151, a text or an image representing that the portable terminal 100 is a lost terminal may be visually output. The article or image may be output to the display unit 151 as a background screen in the standby mode. If the article or image is a changeable image (eg, a video) instead of a fixed image, it may be easier to attract the learner's attention.

The display unit 151 may display a contact that can be connected to the owner in addition to the notification of the lost state. If the display unit 151 is a touch screen, the learner may press the portion where the contact is displayed to talk to the owner.

The comment or article (or image) may be transmitted from an accessor to the mobile terminal 100 through a short message service or the like, or may be previously stored in the memory 160. In the case of receiving the transmission as described above, the message may include an authentication code for authentication. On the contrary, if the accessor enters the control mode by entering the authentication number after the switching function is executed, a separate authentication code may not be required.

14 is a perspective view showing a remote monitoring function of the mobile terminal 100 according to an embodiment of the present invention.

As can be seen from the example illustrated in FIG. 14, the remote monitoring function refers to a function of grasping the surrounding situation where the portable terminal 100 is located and transmitting the information to the accessor. This allows the accessor or the owner to obtain information that can be the basis for determining where the portable terminal 100 is currently located.

The remote monitoring function is mainly performed by the operation of the camera 121 and / or the microphone 122 of the A / V input unit 120. As shown in FIG. 14, when the camera 121 is activated, the camera 121 acquires an image of an object (ceiling, C) placed in the photographing direction. On the ceiling C, an image in which the sprinkler S and the fluorescent lamp L are installed may be obtained. The microphone 122 records contents broadcast through the speaker P installed in the ceiling C. In addition, it will be possible to obtain an image of the blackboard (B) installed on the wall.

The visual information about the ceiling C and the like and / or the auditory information by broadcasting are transmitted to the terminal 100 ′ of the accessor through the mobile communication module 112. The accessor can grasp the above visual and / or auditory information by using the terminal 100 ', and estimate that the location where the portable terminal 100 is placed is a classroom of a school. In addition, judgment on the current situation of the above classroom may be possible at a certain level based on the above information.

During the collection of visual and / or auditory information as described above, the mobile terminal 100 may be controlled to vibrate. If the mobile terminal 100 is moved or its posture is changed by the vibration, additional visual information may be mainly obtained. When the camera 121 itself is controlled to move by rotating or the like, it is also possible to expect to obtain additional visual information. When the camera 121 is activated, the flash 250 may be activated to create a brighter atmosphere based on the time set in the portable terminal 100.

Unlike the above, the location information module 115 may determine the coordinates of the area where the mobile terminal 100 is located.

15 and 16 are perspective views showing the induction function of the mobile terminal 100 according to an embodiment of the present invention, respectively.

As can be seen in FIGS. 15 and 16, The induction function is mainly a function of inducing the acquirer to return the acquired mobile terminal 100 to the owner. Similar to the status notification function, the induction function is mainly performed by the output unit 150.

As shown in FIG. 15, content indicating that the owner is looking for the mobile terminal 100 may be output to the display unit 151. In addition, the location of the owner can be output, preferably it is desirable for a quick return to induce a contact to be output immediately. If the owner's contact information is output in the form of an icon or the like on the display unit 151 which is a touch screen, the call connection can be made more quickly by touching the icon.

It is possible to output the above contents through the voice output module 152. It may also be useful to include such cases according to the return of the mobile terminal 100 in the above output content.

Similar to the status notification function, the contents may be previously stored in the memory 160 or received from an owner through a short message service.

Referring to FIG. 16, as the learner manipulates the portable terminal 100, there may be a case in which the portable terminal 100 is operated to slide in an open state along the sliding direction M. FIG. Such an operation is sensed through the sensing unit 140, and the controller 180 controls the mobile communication module 112 to connect a call to the contact point of the owner with or without the execution of the function according to the operation. Can be controlled.

In addition to sliding the mobile terminal 100 in an open state, the mobile terminal 100 is returned by operating the operation unit 130 (refer to FIG. 1) to make a call to a contact other than the owner's contact, accessing the Internet, and the like. Such a call connection can be attempted even when an operation is performed that is not related to the effort.

In such an act, it would be desirable for the benefit of the owner to exclude the execution of the function corresponding to the manipulation. However, in the case of an operation for receiving a call from an accessor, such a call connection attempt will not be necessary.

If the locking function for the mobile terminal 100 is intended to prevent misuse or abuse of the mobile terminal 100 by the learner, the above call connection function may perform the locking function and return the mobile terminal 100 to the owner. There is an advantage in that it is higher.

17 is a perspective view illustrating a guide function of the mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 17, the guide function is a person who is not an owner or an acquirer, and a person who tries to make a call with the owner (hereinafter, referred to as a “third party”) uses the terminal 100 ″ to use the portable terminal 100. In case of attempting to make a call connection with the user, the owner responds to the call connection request in consideration of a situation in which the owner does not possess the mobile terminal 100.

To this end, the controller 180 of the mobile terminal 100 may transmit the owner's contact information to the third party's terminal 100 ″ via the short message service in response to the third party's call connection request.

In contrast, the controller 180 temporarily holds a call connection request for the mobile terminal 100 in a state in which the owner does not possess the mobile terminal 100 (sets a contact). It can also switch as a call connection for.

18 is a perspective view illustrating an information output function of the portable terminal 100 according to an embodiment of the present invention.

As shown in FIG. 18, when the portable terminal 100 is found, the owner may want to know information related to the remote control executed by the portable terminal 100. For this purpose, the history related to the execution of the remote control is stored in the memory 160.

When the owner operates the operation unit 130 or the like of the portable terminal 100, the portable terminal 100 causes a password (command) to be input. If the password is the same as the set number, the mobile terminal 100 outputs the above contents.

The above output may be a visual and / or audio output using the output unit 150, but will typically be a visual output as shown.

The visual output includes the time the remote control was executed and the remote control function. A state change (transmission, change, etc.) of the specific portable terminal 100 according to the above remote control function may also be included.

In the case where the data is transmitted, the name of some kind of data, for example, a photo file, an image file, or a video file, may be specifically output. Also in the case of the above change, what kind of change has been specifically made, for example, who has been added to the phone book and the like can be output.

If there is a lot of above output content and it is difficult to sufficiently display on the display unit 151, the scroll bar may be displayed together. If the display unit 151 is a touch screen, the above information may be grasped at a glance by touching and dragging the scroll bar.

The contents related to the above state change may be output in the order of the time when the change is made, but may be output in groups of similar types or contents of files. In the former case, the aforementioned scroll may be useful, and in the latter case, details of the selected group may be output by selecting an icon representing each group. If the display unit 151 is a touch screen, the process of selecting and executing the icon may be easier.
