The present invention relates to a wireless communication system, and more particularly, to a parent-child relationship setting system and method in which a parent terminal controls a child terminal by establishing a parent-child relationship between terminals in a wireless communication system.

In general, in a wireless communication system, a terminal receiving a service from a network, that is, a base station of the network, has a characteristic of a user interface, that is, the terminal is a user-oriented device operating through a user, and the portable terminal operates independently. And the terminal operates according to the user's operation as described above. Thus, the terminal receives a user command through a user's key operation and the like and accordingly performs an operation corresponding to the user command.

Thus, a case in which the terminal uses a communication service or an additional service will be described with reference to FIG. 1 below.

FIG. 1 is a flowchart schematically illustrating an operation of a terminal using a communication service and an additional service of a terminal in a general wireless communication system.

Referring to FIG. 1, in step 102, the terminal requests a communication service or an additional service to be provided by the terminal to a network providing a service to the terminal, and proceeds to step 104. In step 104, the terminal receives a communication service or an additional service from the network according to the service request.

Therefore, the terminal can perform the service requested by the terminal without any limitation due to the characteristic of the user-centered device.

In addition, the terminal currently provides only a voice call service between users, and currently provides not only the voice call service but also a video call service for performing user-to-user communication through an image between users. In addition to the above-mentioned call service, various additional services are applied, and the types thereof are innumerably diverse. For example, the additional services include various data services for receiving information such as fortune-telling, traffic, learning, and the like, a location service, and a text service.

In using such a communication service and an additional service in a terminal, the terminal user has expanded, for example, from the increase in the penetration rate of the terminal to the youth and the infant. In practice, however, there is a possibility that they can use the additional service used in the terminal without control, but it is impossible to control this easily due to the characteristics of the terminal and the user-oriented device. To this end, service providers providing services to the terminal have attempted to solve the above problems through various rate plans. However, there is still a problem that the fundamental problem cannot be solved because the terminal is not actually controlled.

In addition, when it is desired to check internal information used in the terminal, for example, the type and information of an additional service being used in the terminal, and the reception and transmission call log information of the terminal for a legitimate purpose, There is a problem in that it is impossible to collect the terminal internal information and transmit it to a specific terminal.

In addition, when the terminal user wants to make an urgent call when the user set the functions such as call forwarding, rejection, etc., the terminal does not know whether the call is received from a specific terminal. . Thus, there was a problem in that in such an urgent situation, remote control of the called terminal in real time to release a function such as a call ban, rejection, etc., thereby making a call with the terminal impossible.

Accordingly, in order to solve the above problems due to the inability to perform control operations between terminals, it was necessary to establish a controllable relationship between the terminals to control terminals that can be controlled by a specific terminal.

Accordingly, an object of the present invention is to propose a system and method for establishing a parent-child relationship between terminals in a wireless communication system for setting terminals having a controllable relationship between a specific terminal and controlling the terminals.

The method of the present invention for achieving the above object; A method for establishing a parent-child relationship between terminals in a wireless communication system, the method comprising: establishing a parent-child relationship with the second terminal when the first terminal wants to control an operation of the second terminal; When a parent-child relationship is established between the first terminal and the second terminal, the first terminal transmits control information to the second terminal, and the second terminal receiving the control information receives the control information. And setting an operation of the second terminal to perform a control operation to be controlled by the first terminal.

The apparatus of the present invention for achieving the above object; In a system for establishing a parent-child relationship between terminals in a wireless communication system including a first terminal and a second terminal connected via a network, a parent-child relationship is established to control an operation of the second terminal, and the parent-child A first terminal for controlling the operation of the second terminal by transmitting control information to the second terminal having a relationship established; and when the parent child relationship is established with the first terminal, the control information is received and the control information is used. It characterized in that it comprises a second terminal for setting the operation.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

The present invention establishes a parent-child, or master-slave relationship, between terminals in a wireless communication system to remotely perform real-time control of operations of one or more terminals set as their children by a wireless communication terminal set as a parent.

Thus, in the present invention, the first terminal, that is, the parent terminal and the second terminal, that is, the child terminal, establish a parent-child relationship by transmitting the messages for establishing the relationship through the network, and the first terminal transmits the message to the second terminal. The control information is transmitted to set an operation of the second terminal.

Then, a parent-child, that is, a master-slave relationship is established between the terminals so that the parent terminal controls the child terminal and subsequently releases the parent-child relationship between the terminals. This will be described with reference.

2A to 2C are signal flow diagrams schematically illustrating an operation process according to a parent-child relationship between terminals in a wireless communication system according to an exemplary embodiment of the present invention.

2A through 2C, a P-terminal 200, a C-terminal 230, and a network 260 are illustrated.

The P-terminal 200 to establish a parent-child relationship transmits a relationship establishment message to the network 260 (step 201). The relationship establishment message includes a relationship establishment code for establishing a parent-child relationship between terminals, and an identification number of the terminal for establishing a parent-child relationship, for example, a telephone number. In this case, it is assumed that the P-terminal 200 is a parent terminal and the C-terminal 230 is a child terminal. Thus, in setting up a parent-child relationship, consider a case where a parent terminal first transmits a setup request message for setting up the parent-child relationship. In addition, it is assumed here that the relationship establishing code, that is, a specific identification code for establishing a parent-child relationship, is '# 9 #' as an example.

When the network 260 receives the relationship establishment request message, the network 260 transmits an acknowledgment (ACK) signal to the P-terminal 200 (step 203). The ACK signal is a response signal for acknowledging a message or an acknowledgment message for transmission success.

The network 260 recognizes that it is a parent-child setting code through the relationship setting code (# 9 #) transmitted by the P-terminal 200, and the C-terminal that the P-terminal 200 wants to set up a parent-child relationship. The relationship setting request message is transmitted to the terminal 230 (step 205). The relationship establishment request message sent to the C-terminal 230 includes a relationship establishment code # 9 # and an identification number of the P-terminal 200. When receiving the relationship request message, the C-terminal 230 transmits an ACK signal to the network 260 (step 207).

The C-terminal 230 recognizes that the code for the parent-child setting through the relationship setting code (# 9 #), and determines whether or not to establish the relationship. Thus, if it is determined to establish the parent-child relationship, the C-terminal 230 determines to establish a parent-child relationship with the P-terminal 200 (step 209). The C-terminal 230 transmits the relationship establishment response message to the network 260 (step 211). The relationship establishment response message includes a relationship establishment password according to a relationship establishment code (# 9 #) and relationship establishment between the C-terminal 230.

When the network 260 receives the relationship establishment response message, the network 260 transmits an ACK signal to the C-terminal 230 (step 213). In this case, the relationship establishment response message received by the network 260 means that the C-terminal 230 accepts the relationship establishment to the P-terminal 200. Accordingly, the network 260 stores information about the parent-child relationship setting of the P-terminal 200 and the C-terminal 230 in the database (step 215). That is, the P-terminal 200 stores the parent terminal and the C-terminal 230 is the child terminal. The relationship setting password of the relationship setting response message is also stored.

The network 260 transmits a relationship establishment completion message to the P-terminal 200 (step 217). The relationship establishment complete message includes a relationship establishment code # 9 # and the relationship establishment password. The P-terminal 200 having received the relationship establishment completion message transmits an ACK signal to the network 260 (step 219).

In addition, the network 260 transmits a relationship establishment completion message to the C-terminal 230 (step 221). The relationship establishment completion message includes, for example, a relationship establishment code # 9 # to inform the completion of the relationship establishment. When the C-terminal 230 receives the relationship establishment completion message, the C-terminal 230 transmits an ACK signal to the network 260 (step 223).

Then, the P-terminal 200 and the C-terminal 230 that have received the relationship establishment complete message from the network 260 recognize that the relationship is completed. Accordingly, the P-terminal 200 becomes a parent terminal, the C-terminal 230 becomes a child terminal, and the P-terminal 200 establishes a parent-child relationship capable of controlling the C-terminal 230 ( Step 225).

When the parent child relationship is established, the P-terminal 200 transmits control information to the C-terminal 230 to control the operation of the C-terminal 230. The P-terminal 200 transmits a control message for controlling the C-terminal 230 to the network 260 (step 227). At this time, the P-terminal 200 sets control functions such as limiting the number of possible calls, controlling the possible number of times, controlling the number of possible calls, controlling the use of accessible data services, canceling the incoming call or the rejection function, and requesting terminal information. The control message includes a relationship setting code # 9 # and a relationship setting password set in the C-terminal 230.

The control message is a message transmitted by the P-terminal 200 for the operation of the C-terminal 230, and even in the case of transmitting the control message, in the relationship establishment request message, relationship establishment response message, relationship establishment completion message, and the like. Use relationship setting code (# 9 #). Thus, the present invention recognizes that the P-terminal 200, the C-terminal 230, and the network 260 are information according to the relationship setting using a relationship setting code (# 9 #) and the like. The message using will be described with reference to Table 1 below.

The relationship setting code is '# 9 #', and when the parent-child relationship is set, the relationship setting code and the message classification code are transmitted together, and when '# 9 # + 0' is received, the relationship setting message is recognized. In addition, when '# 9 # + 1' is received, it is recognized that the parent-child relationship release message is terminated. Accordingly, the message related to the parent-child relationship setup includes not only the relationship setup code but also message classification codes such as '0', and the message related to the parent-child relationship release also includes message classification codes such as '1'. Include.

When the P-terminal 200 and the C-terminal 230 have a parent-child relationship, and the parent terminal, that is, the P-terminal 200 transmits a control message, the relationship setting code and the control as described above. A message classification code indicating information, a code according to each control information to be controlled, and control information according to each message are transmitted. In the case of transmitting a control message including control information for limiting the number of calls available among the control information, "# 9 # + 9 + 0 " and the number of available calls are transmitted to the child terminal, that is, the C-terminal 230 through the network. Will be sent.

When the P-terminal 200 wants to control the transmission possible time of the C-terminal 230, it transmits '# 9 # + 9 + 1' and the transmission possible time control information. And, if you want to control the callable number '# 9 # + 9 + 2' and the callable number information is transmitted, and if you want to cancel the call forwarding or rejection function '# 9 # + 9 + 3' Send or add the Do Not Disturb or Do Not Disturb information. In addition, if you want to receive the information of the C-terminal 230, the request for information to obtain from the '# 9 # + 9 + 4' and the C-terminal 230, the request information is, for example, Information such as a transmission / reception call record (call count, call duration) can be transmitted.

When the network 260 receives a control message including the control information, that is, a message including "# 9 # + 9", the network 260 transmits an ACK signal to the P-terminal 200 (step 229). Thus, in the network, the relationship between the P-terminal 200 and the C-terminal 230 is authenticated using the relationship setting password included in the control message received from the P-terminal 200.

When the parent-child relationship between the P-terminal 200 and the C-terminal 230 is confirmed using the password or the like, the network 260 transmits the control message to the C-terminal 230 corresponding to the corresponding terminal. (Step 231). The control message includes a relationship setting code and control information to be controlled by the P-terminal 200 as described above.

Upon receiving the control message, the C-terminal 230 transmits an ACK signal to the network 260 (step 233). According to the control message transmitted from the P-terminal 200, the C-terminal 230 sets an operation corresponding to the control message (step 235).

For example, when the information included in the control message is a control message for controlling the number of calls available, and the maximum number of calls available in the control information is set to 10 times a day, the C-terminal 230 is the maximum. The number of possible calls is set 10 times, and if the number of calls made through the terminal more than 10 times per day is set to be impossible.

When the operation according to the control information is completed, the C-terminal 230 transmits an operation setting completion message to the network 260 (step 237). The operation setting completion message includes the relationship setting code # 9 #. The network 260 transmits the operation setting completion message to the P-terminal 200 which is a parent terminal of the C-terminal 230.

Thus, through the above-described operation, the P-terminal 200 and the C-terminal 230 establish a parent-child relationship, and the P-terminal 200 transmits control information to set the operation of the C-terminal 230. do.

When the parent-child relationship is released from the C-terminal 230, the C-terminal 230 transmits a relationship release request message to the network (step 241). The relationship release request message includes a relationship establishment code # 9 # and an identification number of the P-terminal 200 that is the parent terminal of the C-terminal 230.

When the network 260 receives the disassociation request message, the network 260 confirms the parent-child relationship setting between the P-terminal 200 and the C-terminal 230 by using the C-terminal 230 and normalizes the disassociation request message. In step 243, an ACK signal indicating that the received signal is transmitted is transmitted. The network 260 transmits a disassociation request message to the P-terminal 200 (step 245). Upon receiving the relationship release request message, the P-terminal 200 determines whether to release the relationship to the C-terminal 230 and transmits the relationship release message to the network 260 in step 247. When the network 260 receives the disassociation message of the P-terminal 200, the network 260 deletes the content of recording the parent-child relationship between the P-terminal 200 and the C-terminal 230 recorded in the database ( Step 249).

The network 260 transmits a relationship release completion message to the P-terminal 200 indicating that the parent-child relationship with the C-terminal 230 has been released (step 251). The relationship release completion message includes a relationship setting code # 9 #. When the P-terminal 200 receives the disassociation completion message, the P-terminal 200 transmits an ACK signal to the network 260 (step 253).

In addition, the network 260 also transmits a disconnection completion message to the C-terminal 230 (step 255). The relationship release completion message also includes a relationship setting code # 9 #. When the C-terminal 230 receives the disassociation completion message, the C-terminal 230 transmits an ACK signal to the network 260 (step 257).

In FIG. 2, the parent terminal, that is, the P-terminal 200 in the setting of the parent-child relationship has been described in consideration of the first setting of the parent-child relationship. On the contrary, the C-terminal 230 may first apply the establishment of the parent-child relationship. In addition, the C-terminal 230 has also been described in consideration of performing the parent-child relationship release first. Conversely, the P-terminal 200 may perform the release of the parent-child relationship first.

In the flowchart, a description has been given focusing on a parent terminal controlling a child terminal and one child terminal controlled by the parent terminal. However, this is described as an example for convenience of description, and it is a matter of course that the parent terminal can operate by establishing a parent-child relationship with one or more child terminals.

Next, the operation of a parent terminal, a child terminal, and a network operating by establishing a parent-child relationship will be described. The ACK signals in the system for setting the parent-child relationship are acknowledged and transmitted. Since the message confirms success, the operation of the ACK signal will be omitted below.

Next, the operation of the parent terminal will be described with reference to FIG. 3.

3 is a flowchart schematically illustrating an operation process of a parent terminal according to a parent-child relationship setting between terminals in a wireless communication system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step 301, a specific terminal, that is, a parent terminal, generates a relationship setting request message of a terminal in order to establish a parent-child relationship with another terminal, and proceeds to step 303. In this case, the relationship establishment request message includes a relationship establishment code for establishing a parent-child relationship, a message classification code, and an identification number of a child terminal for establishing a parent-child relationship.

In step 303, the parent terminal transmits the relationship establishment request message to the network to which the parent terminal belongs and proceeds to step 305. In step 305, the parent terminal receives a relationship establishment completion message corresponding to the relationship establishment request message, and proceeds to step 307. The relationship setting completion message also receives a relationship setting password for authentication, etc., in connection with a child terminal according to the relationship setting.

In step 307, the parent terminal establishes a parent-child relationship with the child terminal for establishing a relationship in response to receiving the relationship establishment completion message, and proceeds to step 309. Accordingly, the parent terminal having the parent-child relationship can transmit a control message to the child terminal to control the operation of the child terminal.

In step 309, the parent terminal is in a standby state, and then proceeds to step 311 or 319. In step 311, the parent terminal determines whether or not to control the child terminal in the parent-child relationship, and if it is desired to control the child terminal proceeds to step 313, and if it does not control the child terminal in step 309 Proceed to

In step 313, if the parent terminal wants to control the child terminal, the parent terminal generates a control message and proceeds to step 315. In this case, the control message includes a relationship setting password for authentication with the terminal, a relationship setting code according to a parent-child relationship setting, a message classification code indicating that the message includes control information, and control according to a function in each control information. Information code, control information, and the like. The parent terminal controls the operation of the child terminal through the control message.

In step 315, the parent terminal transmits the control message to the network and proceeds to step 317. In this case, the control information transmitted by the parent terminal may include, for example, information on the number of possible calls, the available time, the possible number of calls, the control of the use of the data service, the cancellation of the incoming call or the rejection function, the request for information, etc. of the child terminal. . Accordingly, the parent terminal can set and perform not only the control operation but also various control operations through the control message.

In step 317, the parent terminal receives an operation setting completion message and proceeds to step 309. Thus, the parent terminal receives the operation setting completion message and confirms that control information of a control message transmitted from the parent terminal has been applied to the child terminal.

In step 319, the parent terminal checks whether the relationship release request message has been received through the network. If the parent terminal does not receive the relationship release request message as a result of the check, step 309 is performed. However, if the parent terminal receives the relationship release request message as a result of the check, step 321 is performed. When the relationship release request message is received, the child terminal transmits a message for release of a parent-child relationship to the parent terminal. In addition, the relationship release request message includes an identification number of the child terminal that requests the current relationship release. In particular, when the parent terminal controls a plurality of child terminals, the parent terminal can recognize the child terminal to release the parent-child relationship.

In step 321, the parent terminal determines whether to release the parent-child relationship with the child terminal in response to the relationship release request message. Thus, if the parent terminal does not release the parent-child relationship with the child terminal as a result of the check, step 309 is performed. However, if the parent terminal is to release the parent-child relationship with the child terminal as a result of the check proceeds to step 323.

In step 323, the parent terminal transmits the relationship release response message to the network and proceeds to step 325. The relationship release response message includes a relationship setting password for authentication of the child terminal. In step 325, the parent terminal receives a disconnection completion message from the network and proceeds to step 327. In step 327, the parent terminal releases the relationship setting with the child terminal that transmitted the relationship release request message in response to receiving the relationship release completion message.

In the above, the operation of the parent terminal has been described. Next, the operation of the child terminal according to the parent terminal and the parent-child relationship is set with reference to FIG. 4.

4 is a flowchart schematically illustrating an operation process of a child terminal for establishing a parent-child relationship between terminals in a wireless communication system according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in step 401, the child terminal receives the relationship establishment request message from the network to which the child terminal belongs and proceeds to step 403. The relationship establishment request message includes an identification number, a relationship establishment code, a message classification code, and the like of a parent terminal for establishing a parent-child relationship with the child terminal.

In step 403, the child terminal determines whether to establish a parent-child relationship. Thus, if it is determined that the parent-child relationship is not set, the process proceeds to step 401, and if it is determined that the parent-child relationship is set, the process proceeds to step 405.

In step 405, the child terminal transmits a relationship establishment response message according to the relationship establishment request message to the network, and proceeds to step 407. The relationship establishment response message includes the relationship establishment code, the message classification code, a relationship establishment password for accessing the child terminal, and the like.

In step 407, the child terminal receives a relationship establishment completion message and proceeds to step 409. In step 409, the child terminal establishes a parent-child relationship using the terminal that transmitted the relationship setting request message as a parent terminal according to the reception of the relationship setting completion message. As such, when the parent-child relationship is established, the child terminal controls the operation inside the terminal through a control message transmitted from the parent terminal.

In step 411, the child terminal is in a standby state, and then proceeds to step 413 or 419. In step 413, the child terminal checks whether a control message has been received. If the child terminal does not receive the control message as a result of the check, step 411 is performed. However, if the child terminal receives the control message as a result of the check, step 415 is performed.

In step 415, the child terminal sets an operation according to the control information included in the control message and proceeds to step 417. At this time, the child terminal is to set the control information for the operation setting in the parent terminal to the terminal. If the operation information to be set in the parent terminal to the child terminal is, for example, the number of possible calls, the control of possible calls, the control of the possible number of calls, the control of the use of data services, the prohibition of incoming calls, or the rejection of the child terminals. In case of an information request, a corresponding operation is set in the child terminal.

In step 417, the child terminal transmits an operation setting completion message according to the operation setting to the network, and proceeds to step 411.

In operation 419, the child terminal determines whether to release a parent-child relationship with the parent terminal. Thus, if the child terminal does not release the parent-child relationship as a result of the determination, step 411 is performed. However, if it is determined that the child terminal wants to release the parent-child relationship, the process proceeds to step 421.

In step 421, the child terminal transmits the relationship release request message to the network. In this case, the relationship release request message includes an identification number of a parent terminal to be released by the child terminal.

In step 423, the child terminal receives a disconnection completion message from the network and proceeds to step 425. In step 425, the child terminal releases the parent-child relationship established with the child terminal and the parent terminal according to the relationship release completion message.

In the above, the operation of the child terminal has been described. Next, the operation of the network according to the parent terminal and the parent-child relationship setting will be described with reference to FIG. 5.

FIG. 5 is a flowchart schematically illustrating an operation process of a network for establishing a parent-child relationship between terminals in a wireless communication system according to an exemplary embodiment of the present invention.

Referring to FIG. 5, in step 501, the network receives a relationship establishment request message from a parent terminal and proceeds to step 503. In this case, the relationship establishment request message includes a relationship establishment code for establishing a parent-child relationship, a message classification code, and an identification number of a child terminal for establishing a parent-child relationship.

In step 503, the network transmits the relationship establishment request message to the corresponding terminal for which the parent terminal wants to establish a parent-child relationship.

In step 505, the network receives a relationship establishment response message corresponding to the relationship establishment request message from a child terminal, and proceeds to step 507. The relationship setting response message includes a relationship setting password of the child terminal.

In step 507, the network stores parent-child relationship setting information between the parent terminal and the child terminal, and proceeds to step 509. At this time, the parent terminal and the child terminal according to the parent-child relationship setting, and the relationship setting password is stored in the database of the network.

In step 509, the network transmits a relationship establishment completion message to a parent terminal and a child terminal according to the parent-child relationship, and proceeds to step 511. Accordingly, the parent terminal and the child terminal complete the parent-child relationship setting, and the parent terminal transmits a control message to the child terminal remotely or in real time through the network to control the operation of the child terminal.

In step 511, the network is in a standby state, and then proceeds to step 513 or 521. In step 513, the network checks whether a control message is received from the parent terminal. If the network fails to receive the control message from the parent terminal as a result of the check, step 511 is performed. However, if the network receives a control message from the parent terminal as a result of the check, step 515 is performed.

In step 515, the network receives the control message from the parent terminal, transmits the control message to the child terminal corresponding to the parent terminal, and proceeds to step 517. At this time, the network searches and confirms the child terminal of the parent terminal that transmitted the control message, and confirms the relationship setting password included in the control message. The network transmits a control message to the terminal when the relationship setting password matches. However, when the network searches for the child terminal of the parent terminal and transmits the control message to the child terminal, the network may confirm with the relationship setting password set using the relationship setting password.

In step 517, if the network receives an operation setting completion message indicating that the control information included in the control message is applied to the child terminal, the network proceeds to step 519. In step 519, the network transmits an operation setting completion message indicating that operation setting is completed in the child terminal, and proceeds to step 511.

In operation 521, the network determines whether a relationship release request message is received from a child terminal. If it is determined that the network has not received the relationship release request message from the child terminal, the network proceeds to step 511. However, if the network receives the relationship release request message from the child terminal, the process proceeds to step 523. When the child terminal transmits the relationship release request message, the relationship release request message includes an identification number of a parent terminal for releasing a relationship.

In step 523, the network transmits the relationship release request message to the parent terminal of the child terminal. Since the relationship release request message includes an identification number of the child terminal, the parent terminal recognizes the child terminal that has received the relationship release request message.

In step 525, the network receives a relationship release response message from the parent terminal and proceeds to step 527. In step 527, the network deletes the relationship setting information between the parent terminal and the child terminal stored in the database through the identification number of the child terminal included in the relationship release response message, and proceeds to step 529.

In step 529, the network transmits a relationship release completion message to the parent terminal and the child terminal.

In the above, the wireless communication system establishes a relationship and transmits a control message between the parent terminal and the child terminal and controls the operation of the child terminal by applying control information included in the control message to the child terminal. Next, an operation process of the terminal in which the control information is set will be described below with reference to FIG. 6.

FIG. 6 is a flowchart schematically illustrating an operation process of a child terminal to which control information transmitted from a parent terminal is applied in a wireless communication system according to an embodiment of the present invention.

Before referring to FIG. 6, the child terminal controls the child terminal through a control message transmitted from the parent terminal according to the above-described parent-child relationship setting. The type of control message for controlling the child terminal may vary, and as described below with reference to FIG. 6, various embodiments may be implemented.

Referring to FIG. 6, in step 601, the terminal determines whether the current number of calls is less than the number of possible calls set in the terminal. If the current number of calls is greater than or equal to the number of available calls set in the terminal, the process proceeds to step 609 to perform the operation set in the terminal. However, if the current number of calls is less than the number of available calls set in the terminal, the flow proceeds to step 603.

Here, in step 601, confirming the number of possible calls is to perform a control operation through a control message for controlling the number of possible calls. The limit on the number of calls allowed controls the maximum number of calls for a certain period of time. For example, if the number of calls is limited to 30 within a week, only 30 calls can be made for a week, and more than 30 calls can be made. Set this to be restricted.

In step 603, the terminal determines whether the time of the current terminal is within a range of available talk time set in the terminal. As a result of the determination, if the current time of the terminal is in the range of the non-call time, the process proceeds to step 609 to perform the control operation set in the terminal. However, if it is determined that the current time of the terminal exists within the range of available call time, the process proceeds to step 605.

In the step 603, the call available time is set by the parent terminal to perform a control operation through a control message for controlling the call available time. For example, when the callable time is set to '06: 00-24: 00 ', the call is set to be allowed within the above time range and the call is limited to other times.

In step 605, the terminal checks whether a communication service to be used in the terminal is an international call. If the check result is that the service to be used in the terminal is an international call, the process proceeds to step 609 to perform a control operation set in the terminal. However, if the service to be used in the terminal is not an international call, the process proceeds to step 607.

In step 605, whether the call is an international call is performed by the parent terminal through a control message for restricting the international call. For example, when the terminal sends an international call code or an international phone number for international call use, the call is restricted to be prohibited.

In step 607, the terminal checks other control conditions applied to the terminal in addition to the above-described control operation. If the test result does not satisfy the other control condition applied to the terminal, the control proceeds to step 609 to perform the set control operation. However, if the test result satisfies all other control conditions, the terminal proceeds to step 611.

In step 607, in addition to the control operations described in steps 601, 603, and 605, operations such as callable number control may be extended.

In step 611, the terminal requests a communication service or an additional service to the network to which the terminal belongs and proceeds to step 613. In step 613, the terminal uses a communication service or additional service according to the communication service or additional service request.

In FIG. 6, an operation of the terminal, that is, the child terminal, which has received the control message has been described.

In addition, the parent terminal may release the child terminal if the current terminal is set to call rejection or rejection. When the parent terminal desires to receive information in use by the child terminal, the parent terminal requests information of the child terminal through a control message. Then, the child terminal collects the information set in the child terminal and transmits it to the parent terminal. In addition, when the terminal makes a prohibited call from the terminal, the terminal transmits the information on the prohibited call to the parent terminal.

As a result, the parent terminal and the child terminal can control the operation of one or more child terminals by establishing a parent-child relationship. When the parent terminal includes a plurality of child terminals through a plurality of parent-child relationships, the plurality of terminals are controlled by managing the child terminals with a list of child terminals.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

The present invention as described above has the advantage that it is possible for the parent terminal to control the operation of the child terminal by establishing a parent-child relationship between terminals in a wireless communication system. In addition, it is possible to control the use of the terminal users, that is, teenagers, infants, and the like, by controlling parent-child relationships between the terminals. In addition, by transmitting control information between the terminals to control the other terminal, there is an advantage that can provide a new additional service to the user.
