Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that, in the drawings, the same components are denoted by the same reference numerals as possible. Further, the detailed description of known functions and configurations that may obscure the gist of the present invention will be omitted.

The present invention can remotely control a portable terminal that is lost or not carried in the case where the portable terminal is lost or not carried so that a desired function can be performed in another terminal or a service can be provided. Hereinafter, a method based on a mobile tracking function will be described as an example of a technique for remotely controlling a mobile terminal in the present invention. When the mobile terminal in which the movement tracking function is operated is lost, the mobile terminal tracks a message informing another terminal that has been previously set when the subscriber identity module (SIM) changes, It is a function to transmit. It should be noted that although the following description refers to the movement tracking function, the remote control method for the functions to which the present invention is applied is not limited to the method based on the movement tracking function. A method for remotely controlling the functions of the mobile terminal using the movement tracking function will be described in detail with reference to the drawings.

1 is a block diagram illustrating a system for remotely controlling functions of a mobile terminal according to an exemplary embodiment of the present invention. In the present invention, it is assumed that a mobile tracking function is used for remote control, and a message transmitted and received between a slave terminal and a master terminal is a short message service (SMS) message. Therefore, the structure of a mobile communication system for transmitting an SMS message will be described by way of example in FIG. However, it can be remotely controlled by a function other than the movement tracking function by a remote control method, and can be transmitted by a message format other than an SMS message. It can be transmitted to another network other than the mobile communication network if it is transmitted by a different message format. It is needless to say that the system structure of FIG. 1 can be changed according to another network.

Referring to FIG. 1, a mobile station (MS) 101 may be a slave terminal as a mobile terminal for which a remote control function is set, and a mobile terminal MS2 102 may be a master terminal that remotely controls the MS1 101. Base stations (BS) 111 and BS2 112 are bases for managing MS1 101 and MS2 102 and MS1 101 and MS2 102 are in the same cell Cell), it can be one base station. BS1 111 and BS2 112 are connected to MS1 101 and MS2 102 via a radio link and communicate with MS1 101 and MS2 102, respectively. A Mobile Switching Center (MSC) 120 processes signals transmitted from and received by BS1 111 or BS2 112, controls base stations and, if necessary, moves the location of MS1 101 or MS2 102 Contact the Home Location Register (HLR) 140.

The SMSC 130 is connected to the HLR 140 and the MSC 120 to identify the location of the MS1 101 or the MS2 102 and transmits an SMS message to the user of the mobile terminal If the transmission of the SMS message to the receiving-side mobile terminal that can not be received at an arbitrary moment is requested, the message can be stored for a predetermined time and forwarded. When the MS1 101 or the MS2 102 transmits an SMS message for the remote control function according to the present invention, the BS1 111 or the BS2 112 receiving the SMS message transmits the SMS message to the MSC 120, And transmits the received signal to the SMSC 130 because the received signal is an SMS message. The SMSC 130 checks whether the receiving terminal of the received SMS message, that is, the MS1 101 or the MS2 102, is in a state of receivable, and transmits the received SMS message to the receiving terminal when it is possible to receive the SMS message. The HLR 140 stores subscriber information such as locations of mobile terminal users. Although the MS1 101 or the MS2 102 has been described as an example of a mobile communication terminal, it can be changed to a personal data assistance (PDA), a smart phone, etc. in addition to the mobile communication terminal Of course.

2 is a block diagram illustrating a configuration of a mobile terminal according to an embodiment of the present invention. The portable terminal shown in FIG. 2 may be the MS1 101 or the MS2 102 of FIG.

2, the wireless communication unit 210 performs wireless communication between the BS1 111 or the BS2 112 and the portable terminal 101 or 102 in FIG. In particular, the wireless communication unit 210 transmits and receives a message for remote control. The wireless communication unit 210 includes a frequency transmitter for up-converting and amplifying the frequency of a transmitted signal, a frequency receiver for low-noise amplifying the received signal and down-converting the frequency. The data processing unit 220 processes input data and the like. The data processing unit 220 may include a transmitter for encoding and modulating a signal transmitted through the wireless communication unit 210 and a receiver for demodulating and decoding a signal received through the wireless communication unit 210. That is, the data processing unit 220 may include a modulator / demodulator (MODEM) and a codec (codec / decoder).

The controller 230 controls the overall operation of the portable terminal 101 or 102 and the signal flow between the internal blocks of the portable terminal 101 or 102. The control unit 230 may include a data processing unit 220. The control unit 230 may include a remote control unit 232 for performing an overall remote control function and a control message unit 234 for generating and analyzing a remote control message. The remote control unit 232 sets a remote control function in the case of the MS1 101 of FIG. 1, checks whether a message is a remote control message or a general SMS message when a message is received, And then performs the corresponding remote control function if they match. The functions performed by the remote control unit 232 and the control message unit 234 may differ depending on whether the remote control unit 232 and the control message unit 234 are provided in the MS1 101 or the MS2 102 in FIG. For example, the remote control unit 232 provided in the MS2 102 requests a remote control function, and the control message unit 234 generates a message to request the remote control unit 232. The remote control unit 232 included in the MS1 101 Controls the corresponding function according to the information included in the remote control message received from the MS2 102. The control message unit 234 analyzes the received remote control message and extracts the included information. In the case of a message informing of the change of the receiving side terminal (Recipient), a message informing the receiving side terminal change is generated by the control message part 234 of the MS1 101, It is confirmed that the message received by the receiving terminal 234 is a message informing the receiving terminal change. A detailed description of the remote control function will be given later with reference to Figs. 3 to 7. Fig.

The storage unit 240 stores application programs and various data necessary for performing the functions of the portable terminal 101 or 102. Also, the storage unit 240 may store information on the remote control function set by the remote control function. The display unit 250 displays screen data generated during the execution of the program, and displays an input key operation state by a user or the like. The display unit 250 may be formed of a liquid crystal display (LCD), and when the LCD is formed as a touch screen, the display unit 250 may include a display unit 250, Function can also be performed.

Although not shown in FIG. 2, a SIM card (not shown) including user identification information of the portable terminal 101 or 102 may be mounted. When the SIM card is mounted, It is possible to know whether the loss event has occurred or not by checking whether or not the change has occurred.

3 is a flowchart illustrating a process of remotely controlling functions of a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 3, it is assumed that the MS1 101 of FIG. 1 is a slave terminal having a remote control function , and the MS2 102 remotely controls the function of the MS1 101. FIG. That is, the MS1 101 is a portable terminal that is remotely controlled, and the MS2 102 is a terminal operated by a user to control the MS1 101. [ It is also assumed that the MS2 102 is set by the telephone number of the MS2 102 or the like as the message receiving side terminal in the remote control function set in the slave terminal. The process of setting the remote control function and the changing process of the receiving side terminal will be described later with reference to FIG. 6 and FIG.

In step 310, the MS1 101 has the remote control function turned on. In order to control the function of the MS1 101 remotely, the MS2 102 selects a function to be remotely controlled in step 320. [ Here, the selection of the function to be remotely controlled can be performed by an input from the user through the input unit 270 of FIG. At this time, the MS2 102 may request the list of the functions that can be provided by the MS1 101 for selecting the function, and may select the list from the received list after receiving the list of the corresponding functions from the MS1 101. [ The remote control function may be a function that can be performed in place of the MS2 102 among the functions provided by the MS1 101, for example, a call barring function and a forwarding function. The remote control setting of the specific function will be described later with reference to Fig. In step 330, the MS2 102 requests the MS1 101 to transmit information about the selected remote control requesting function. At this time, the information may be transmitted by an SMS message.

In step 340, the MS1 101 and the MS2 102 perform an authentication process. At this time, in the authentication process, the MS1 101 queries the MS2 102 for an authentication number such as a password, and when the authentication number input from the MS2 102 is received, the received authentication number is transmitted to the MS1 101 And confirming whether it matches the pre-stored authentication number. The MS1 101 performs subsequent steps for setting up the remote control for the requested function from the MS2 102 when the authentication numbers match each other. If the authentication numbers do not coincide with each other, the MS2 101 transmits an authentication number mismatch Quot; At this time, the authentication number inquiry to the MS2 102 may be performed once, or the authentication number revalidation inquiry procedure may be performed a predetermined number of times. Also, the authentication number information included in the message transmitted in step 330 may be used. That is, the MS1 101 can confirm whether or not the MS2 102 is authenticated by confirming whether or not the password included in the received message, that is, the authentication number, matches the authentication number stored in advance. In FIG. 3, it is assumed that the MS1 101 verifies that the authentication numbers coincide with each other.

In step 350, the MS1 101 analyzes the received message and sets a remote control function for the requested function. Here, the message analysis is to confirm information about the remote control function contained in the received message. This is possible under the assumption that the received message is a message for remote control, and confirms whether the message is a message for remote control or a general SMS message upon receiving the message. That is, before performing the authentication process in step 340, the MS1 101 can confirm whether the received message is a message for remote control. It is assumed that the MS1 101 and the MS2 102 can distinguish a message for remote control and a general SMS message according to a predetermined protocol. After analyzing the message, the MS1 101 establishes a remote control for the remote control request function contained in the message. For example, if the function included in the received message is a remote control request for the call restriction function, the type of call to be restricted is checked. The types of call restriction may include an outgoing call restriction, an international call restriction, an incoming call restriction, a roaming restriction, and the like, which are originated by the MS1 101. [ Also, if the function included in the received message is a remote control request for the forwarding function, the type of the call or message requesting forwarding and the terminal information requesting the forwarding are confirmed. The type of call or message requesting forwarding may include a call, an SMS message, a multimedia messaging service (MMS) message, and the like. A detailed description thereof will be described later with reference to Fig.

In step 360, the MS1 101 transmits a message to the MS2 102 indicating that the setting of the remote control function for the requested function is completed. In this case, when the forwarding function, particularly the message forwarding function, is set, forwarding of previously received and stored messages is requested, and the corresponding messages are transmitted to the MS2 102. In step 370, the MS1 101 detects occurrence of an event corresponding to the set function. For example, when the call restriction function is set, there may be a case where a limited call occurs, that is, a call origination request occurs in an outgoing call restriction setting, or a call reception occurs in an incoming call restriction setting. Or when a message forwarding function is set, a message corresponding to the set message type may be received. In this case, the MS1 101 uses the pre-stored reception-side terminal information in the case where a message corresponding to a function set in step 380, for example, transmission or reception restriction for an outgoing call or an incoming call, And delivers the received message to the receiving terminal.

Thus, according to the present invention, when the portable terminal is lost or not carried, it is possible to control the function of the terminal that is lost or not carried by using another terminal set in advance.

4 is a flowchart illustrating a remote control setting process for a function according to an embodiment of the present invention. 4, the process of setting the remote control for the requested function after analyzing the message in step 350 of FIG. 3 is shown in detail.

Referring to FIG. 4, the MS 1 101, particularly the control message portion 234 of FIGS. 2 and 3, analyzes the remote control message in operation 410. At this time, the analysis of the remote control message means that the function for requesting the remote control included in the message is confirmed and the information about the requested function is extracted. The extracted information includes the type of the requested function and information about the receiving terminal. The MS1 101, in particular, the remote control unit 232 compares the requested remote control function and the receiving terminal information with the requested remote control function and the receiving terminal information. If it is determined that the two pieces of information match, the remote controller 232 proceeds to step 440. Otherwise, the remote controller 232 proceeds to step 490 and transmits a message informing that the requested remote control function can not be set to the MS2 102 ). At this time, the remote control message indicating that the remote control function can not be set can be configured in the SMS message format. The SMS message format conforms to the international standard. In general, one SMS message may be composed of 140 bytes of user data.

In step 440, the remote control unit 232 determines whether the requested remote control function is a call restriction function or a forwarding function. Here, the call restriction function and the forwarding function are examples of the functions to be remotely controlled. For convenience of explanation, only the two functions are described as an example, but the remote control function of the present invention is not limited to the call restriction function or the forwarding function. If the requested function is the call restriction function, the remote control unit 232 proceeds to step 450, and if the requested function is the forwarding function,

In step 450, the remote control unit 232 confirms the call information requesting the restriction. The call information may include call restriction type, telephone number information, and the like. Types of call restriction may include outgoing call restriction, international call restriction, incoming call restriction, and roaming restriction. The outgoing call restriction is a function for limiting call origination, and may include one or more options depending on the setting of all outgoing calls or the restriction on partial outgoing calls according to conditions such as stored phone numbers and the like. The incoming call restriction is a function for limiting a call incoming, and may include one or more options according to the setting such as restriction on all incoming calls or restriction on an incoming call for a partial incoming call according to a condition such as a stored telephone number . The international call restriction is a function for restricting the use of an international call, and the roaming restriction is a function for restricting roaming to other communication terminals. This call restriction is performed by the MS1 101 itself under the control of the wireless communication unit 210 or the like, or when the call restriction is set, the MS1 101 transmits the call restriction through the BS1 111 of FIG. The call restriction of the MS1 101 in the communication network can be performed. In step 460, the remote control unit 232 sets the requested call restriction function according to the checked call information. By doing so, if there is an incoming or outgoing call for a limited call, the corresponding call is forcibly terminated.

In step 470, the remote control unit 232 confirms information about a call or a message requesting forwarding. Here, the information on the message may include the type of the forwarding message, the recipient, and the sender information. The forwarding message type may include an SMS message, an MMS message, and the like. The call is a voice call signal, the SMS message is a message including short text limited to a certain size or less, and the MMS message is a message including multimedia data. The forwarding function may include forwarding for real-time or non-real-time services in addition to forwarding for the above-mentioned calls, SMS messages, and MMS messages. In addition, forwarding of messages can be performed not only for forwarding requests according to message types such as SMS messages and MMS messages, but also for forwarding functions for the messages received from designated recipients, and forwarding functions using recipient and sender information . In addition, the forwarding function may be selected and set among the various forwarding functions classified according to the settings such as the forwarding function setting for previously received and stored messages or the forwarding function setting for a message to be received later. In step 480, the remote control unit 232 sets the forwarding function according to the confirmed forwarding information. At this time, if the set message forwarding function includes the forwarding function for the previously received messages, the remote control unit 232 sets the forwarding function and transmits the previously received messages to the receiving side terminal, that is, the MS2 102 . If a forwarding function is set for a message to be received subsequently, the MS1 101 sets a forwarding function in step 480. When a message or a call corresponding to the set type is received, that is, an event corresponding to the forwarding function The MS2 102 forwards the received call or message to the receiving terminal.

FIG. 5 is a diagram illustrating screens for setting a remote control function in a slave terminal according to an exemplary embodiment of the present invention. Referring to FIG. FIG. 5 illustrates a process of setting a remote control function in a slave terminal that is remotely controlled, that is, the MS1 101 of FIG. 1 and FIG.

Referring to FIG. 5, when a remote control function is to be set to the MS1 101 of FIG. 1 and FIG. 3, a "Security" menu is displayed on the display unit 250 of FIG. When the remote control function, for example, the "Mobile Tracker" function 512 is selected on the screen 510, the screen is switched to the password input screen 520 for authentication of the movement tracking function. When the password is input through the input unit 260 or the like on the screen 520, the screen is switched to the screen 530 for requesting re-input of the password to confirm the password. At this time, the password re-input screen may be omitted. The password thus set is used for confirming whether or not the password provided from the MS2 102 during authentication in step 340 of FIG.

When the re-input of the password is completed, the screen 540 is switched to select whether the 'move tracking' function is 'On' 542, 'Recipient' information 544, Number, and 'sender' information 546, for example, a telephone number. The mobile tracking function set here, i.e., whether or not the remote control function is activated, and the information of the receiving side and the transmitting side terminals are used to determine whether to perform remote control procedures for the functions in FIGS. For example, when the remote control function is not activated (ON), the MS1 101 does not perform the processes of FIG. 3, and if the information of the MS2 102 The remote control setting disabling notification message is transmitted without performing the function setting process of FIG. By using such information, the present invention can prevent the problem that the functions of the terminal that is lost or not carried are used indiscriminately.

The screen 550 is a screen for setting up the forwarding function, and the information of the forwarding function to which the remote control is to be given is selected. That is, the type of the call or message to be forwarded is set. Screen 550 shows the case of setting up a forwarding function for a call 552, an SMS message 554, and an MMS message 556, either real-time or non-real-time services. When set as screen 550, it is possible to remotely control at least one of the call, SMS message, and MMS message functions in the remote control request for the forwarding function from the master terminal. In other words, when the remote control function information requested in step 420 of FIG. 4 is compared with the set remote control function information, if the remote control function is set as the screen 550, the requested remote control function may include at least one of a call, an SMS message, When the function is requested, it is determined that the requested information matches the set information.

FIG. 6 is an exemplary diagram illustrating screens for setting a remote control function according to another embodiment of the present invention. Referring to FIG.

Referring to FIG. 6, when a remote control function, for example, a mobile tracking function is selected when a remote control function is set to the MS1 101 of FIG. 1 and FIG. 3 as a slave terminal, 250 as shown on the screen 610. When 'Settings' 612 is selected on the screen 610, the screen is switched to the screen 620 for inputting the receiving terminal information and the password. When the receiving terminal information, that is, the remote phone number and the password for authentication are inputted through the input unit 260 on the screen 620, setting of the receiving terminal for the movement tracking function is completed has been set) is displayed as shown on screen 630. Here, for the accuracy of the setting, after the setting is completed as shown on the screen 630, the MS1 101 further performs a process of transmitting a message to the receiving side terminal, that is, the MS2 102, can do. Also, when the message is transmitted to the receiving terminal, the MS1 101 can receive a response message from the receiving terminal in response to the message.

When the setting of the receiving terminal is completed, the screen is switched to the screen 640. When 'Activation' 642 is selected on the screen 640 through the input unit 260 or the like, a screen for selecting whether to activate the remote function 650). When the 'On' 652 indicating the activation of the remote control function is selected through the input unit 260 or the like on the screen 650, the setting for the remote control function is completed. In the present invention, it is assumed that the remote control function is set by the setting process as shown in FIG. 5 or 6 in the MS1 101 of FIG. 1, and the receiving terminal is set as the MS2 102. In the state where the remote control function is turned on in step 310 of FIG. 3, the remote control function is activated as shown in the screen 650 after the remote control function is set to the MS1 101 through the setup process as shown in FIG. 6 On "state.

7 is a diagram illustrating a process of changing receiving terminal information among remote function setting information according to an embodiment of the present invention. FIG. 7 illustrates a process of setting a remote control function when the 'Change Recipient' item is selected on the screen 610 of FIG. The changing of the receiving terminal changes the information about the receiving terminal while maintaining the remote function setting information when there is a change of the receiving terminal after the remote control function is set through the procedures of FIG. 5 or 6.

Referring to FIG. 7, when 'Change Recipient' 712 is selected on the screen 710 for setting the remote control function for the MS1 101 of FIG. 1 and FIG. 3 as the slave terminal 2 on the display unit 250 as shown in the screen 720. [ On the screen 720, new input terminal information and new password are input through the input unit 260. The receiving terminal information may be, for example, a telephone number (New Remote phone number). When the new receiver side terminal information and the new password are inputted on the screen 720, the screen is switched to a screen 730 for inquiring whether to transmit the confirmation message to the changed receiver side terminal. When the confirmation message transmission (YES) 732 to the changed receiving terminal is selected on the screen 730, the MS1 101 transmits a message informing that the receiving terminal information is changed in a predetermined format to the new receiving terminal . After the confirmation message is transmitted, the MS1 101 waits for a response message (Acknowledge) from the new receiving terminal as shown on the screen 740. Upon reception of the response message, the completion of the change of the reception-side terminal information is displayed as in the screen 750. In this way, it is possible to easily change the information that is likely to be changed, for example, the receiving side terminal information without changing all the settings of the remote control function.
