1 is a view showing a schematic configuration of an entire system according to an embodiment of the present invention.

Referring to FIG. 1, the overall system for limiting outgoing and incoming calls includes an originating exchange 130, an originating home location register 140, a receiving side exchange 150, and a receiving home location register 160. can do.

The calling terminal 110 and the receiving terminal 180 are connected to the calling side exchange 130 and the receiving side exchange 150 that provide wired / wireless telephone service through the communication network 1 120 and the communication network 2 170. It is.

For convenience of explanation, although the exchanges are shown separately, in the case where the calling and receiving terminals 110 and 180 are call connections in the same exchange station, the calling exchange 130 and the receiving exchange 150 may be the same exchange.

The calling and receiving terminals 110 and 180 may be applied without limitation as long as they are provided with a communication means and have a wired / wireless terminal capable of a telephone connection. That is, a cellular phone, a PCS phone, a PDA phone and the like are typical examples, but the present invention is not limited thereto.

Communication network 1 (120) and communication network 2 (170) may be a wired / wireless communication network. The wired communication network refers to a communication network capable of providing a wired telephone service, and refers to a current public switched telephone network (PSTN) and an internet network, but the present invention is not limited thereto. In addition, the Internet network may be connected to the telephone network through the Internet phone gateway.

In addition, a wireless communication network refers to a communication network capable of providing a wireless telephone service to a mobile terminal employing a code division multiple access (CDMA), a time division multiple access (TDMA), an IMT2000 scheme, or the like. The wireless communication network includes a base station (BTS, not shown) and a base station controller (BSC, not shown) between the calling terminal 110 / receiving terminal 180 and the calling exchange 130 and the receiving side exchange 150. can do.

The originating home location register (HLR) 140 / receiving home location register 160 refers to a move with information, subscription information, location information and authentication at the exchange.

The home location registers 140 and 160 according to the present invention receive an information request transmission message about the mobile communication subscriber from the exchanges 130 and 150 and transmit corresponding subscriber information to the exchange. The subscriber information may include call restriction service subscription information and an origination / reception allow list.

The call restriction service subscription information according to the present invention is transmitted to and managed by the home location registers 140 and 160 when the subscriber selects the call restriction service in a customer management system (not shown) when the mobile communication terminal is opened. The subscriber may enter the originating or receiving allow list (eg, parent number, etc.) when subscribing to the call restriction service. Of course, the send and receive allow list may be added or changed as necessary. In addition, the input of the list may be made in various ways (for example, input through a PC).

The originating exchange 130 and the receiving exchange 150 are connected to the communication network 1 120 and the communication network 2 170 to enable the wired / wireless telephone service to the calling terminal 110 and the receiving terminal 180. Forward and handle calls.

According to one preferred embodiment of the present invention, the exchanges 130 and 150 provide a service for limiting the call of the subscriber in connection with the home location registers 140 and 160.

When the exchanges 130 and 150 operate as the calling exchange 130, the exchange 130 permits and receives the call restriction service subscription information from the calling home location register 140 according to the call establishment request of the calling terminal 110. Provides call restriction service by receiving outgoing subscriber information including list.

In addition, when the exchanges 130 and 150 operate as the receiving side exchange 150, the exchange 150 requests and limits the call restriction service information from the receiving side home location register 160 according to the call setup request of the calling terminal 110. Provide call restriction service by receiving the receiving subscriber information including allow list.

Hereinafter, the outgoing and incoming call restriction service will be described in detail with reference to FIGS. 2 and 3.

2 is a diagram illustrating an origination process of a call restriction service subscriber according to an embodiment of the present invention.

Referring to FIG. 2, in step 210, the calling terminal 110 transmits a call setup request to the calling exchange 130. The calling terminal 110 is not limited as long as it is a communication means capable of dialing, but in the case of a call restriction service, it may be preferable to regard it as a mobile communication terminal (particularly, a mobile phone).

Receiving the call setup request in step 220, the calling side exchange 130 transmits the calling subscriber information request to the calling side home location register 140 to query the subscriber information.

In step 230, the calling party home location register 140 extracts calling subscriber information (eg, information, subscription information, location information, authentication information, etc.) and transmits subscriber information to the calling party exchange 130. In particular, the subscriber information according to an embodiment of the present invention may be information including whether a caller subscribes to a call restriction service and a reception allow list.

In addition, the reception allow list may include a number set to be received when the mobile communication terminal is opened, and may be a predetermined shortcut number.

In the case of an abbreviated number, the reception allow list further includes number information mapped to the abbreviated number, and may be a parent number if the mobile communication terminal holder is a child.

Here, the speed dial number is a simple number provided in place of the long-term general telephone number used in the past. When using a speed dial number when a call setup request is used, a speed dial number identifier (eg, "*") may be included to distinguish the speed dial number from a general emergency number (eg, "112"). However, it is obvious that the shortcut number according to the present invention is not necessarily used to include a shortcut number identifier, and the shortcut number may be used alone. When a shortcut number identifier is used, the shortcut number identifier is preferably a "*" button (or "#"), but the present invention is not limited thereto.

In particular, if a speed dial number is used for a call between a child and a parent, there will be an effect of not having to memorize a long number excessively. Of course, it is obvious that it can also be applied to non-children.

In step 240, the calling exchange 130 determines whether the calling subscriber is a call restriction service subscriber using the calling subscriber information received in step 230, and if the caller is not a call restriction service subscriber, proceeds to step 250. Send a call setup request to 150.

In step 240, if the caller is a call restriction service subscriber, the flow proceeds to step 260 to determine whether the received number corresponds to a reception allow list. Here, the reception allow list refers to a list of telephone numbers capable of receiving a call transmitted from the calling terminal 110.

On the other hand, the reception number refers to a phone number or a shortcut number corresponding to the terminal to which the call connection. If the received number is not a shortcut number, step 280 may be omitted.

On the other hand, if the received number is a shortcut number, the reception allow list may include a number mapped to the shortcut number.

For example, when the calling side exchange 130 receives the receiving number "* 1" from the calling terminal 110 (ie, the speed dial identifier + speed dial number), the speed dial "1" in the reception allow list. Determine if is present. Of course, if the reception number is a general telephone number, it is determined whether the telephone number exists in the reception allow list.

If the reception number (ie, the speed dial number) does not correspond to the reception allow list in step 260, the calling side exchange 130 transmits a call unavailable guide message to the calling terminal 110. Here, the call unavailable guide message may be a voice message transmitted through an ARS system (not shown).

In step 260, if the recipient shortcut number corresponds to a reception allow list, step 280 is performed.

In step 280, the calling side exchange 130 replaces the received shortcut number with the telephone number mapped thereto, and in step 290, attempts to set up the call with the substituted telephone number. For example, it receives a shortcut number "1" and replaces it with a corresponding telephone number "016-000-0000", and attempts to set up a call with the substituted telephone number.

As described above, step 280 is applied when the received number is a shortcut number, and thus, if the received number is a general phone number, step 280 may be omitted.

3 is a diagram illustrating a reception process of a call restriction service subscriber according to an embodiment of the present invention.

Referring to FIG. 3, in step 310, the receiving exchange 150 receives a call establishment request from the calling exchange 130. As described above, in the case of a call connection in the same exchange station, the calling exchange 130 and the receiving exchange 150 may be the same exchange.

In step 320, the receiving side exchange 150 transmits the receiving subscriber information request to the receiving side home location register 160 to determine subscriber authentication and subsidiary service subscription according to the present invention.

In step 330, the receiving side home location register 160 extracts subscriber information (eg, information of, subscription information, location information, authentication information, etc.) and transmits the subscriber information to the receiving side exchange 150.

In particular, the subscriber information according to an embodiment of the present invention may be information including whether the receiving subscriber subscribes to the call restriction service and the call permission list.

Here, the outgoing allowed list refers to a list of outgoing telephone numbers capable of setting up a call to the receiving terminal 180.

In operation 340, the receiving side exchange 150 determines whether the receiver is a call restriction service subscriber using the receiving subscriber information.

 If the receiver is not a call restriction service subscriber, the process proceeds to step 350 and attempts to set up a call to the receiving terminal 180. The call setup in this case corresponds to a general call connection, of course.

If it is determined in step 340 that the called party is a subscriber to the call restriction service, the process proceeds to step 360 to determine whether the calling party number corresponds to the call permit list. For example, if the caller number is "016-000-0000", it is determined whether the number exists in the call allow list.

If the calling party number corresponds to the originating allow list in step 360, the receiving side exchange 150 attempts to set up a call to the receiving terminal 180 in step 370. The call setup in this case would correspond to the telephone connection according to the invention.

In addition, in step 360, if the caller ID does not correspond to the call allow list, the process proceeds to step 380 and transmits a call impossible guide message to the caller terminal 110. The call unavailable guide message may be a voice message transmitted through an ARS system (not shown).

4 is a diagram showing the configuration of an exchanger according to a preferred embodiment of the present invention.

4, the switch according to the present invention, the control unit 410, subscriber information inquiry unit 420, service subscription determination unit 430, call setup unit 440, reception acceptance determination unit 450, outgoing allowed The determination unit 460, a message manager 470, and a shortcut number manager 480 may be included.

The exchange according to the present invention shown in FIG. 4 may implement all of the functions of the calling exchange 130 and the receiving exchange 150. Of course, it is obvious that the functions of the originating exchange 130 or the receiving exchange 150 may be performed separately.

The controller 410 controls the overall operation of the exchange such as subscriber information inquiry, service subscription determination, call / reception allowance determination, call setup, etc. to limit the call of the terminal connected through the communication network.

When there is a call setup request from the calling terminal 110, the subscriber information inquiry unit 420 may receive subscriber information from the home location register in response to the call setup request.

Here, when the exchange operates as the calling exchange 130, the home location register is the calling home location register 140, the subscriber information may be the calling subscriber information. In addition, when the exchange operates as the receiving side exchange 150, the home location register may be the receiving side home location register 160, and the subscriber information may be the receiving subscriber information.

In addition, the originating subscriber information may include outgoing call restriction service subscription information and a reception allow list, and the reception subscriber information may include reception call restriction service information and an origination allow list. The service subscription determining unit 430 determines whether the subscriber is a call restriction service (for example, a service capable of calling only a specific number or a service capable of receiving a specific number) using the received subscriber information. Perform. For example, the origination restriction service may be a service that can be sent only to a specific number. In addition, when using the above-mentioned shortcut number may be a service that can be installed a specific number and hot line (Hot-Line).

The reception restriction service may be a service that can receive only a specific number, and may be a service that excludes a call attempt from the number. Therefore, by using the present invention, it is possible to block an undesired call by using a function of an exchange rather than a mobile communication terminal.

The call setup unit 440 performs a call setup function between the calling terminal 110 and the receiving terminal 180 when the receiving number corresponds to a reception allow list when the exchange operates as the calling exchange 130. In this case, when the received number is a speed dial number instead of a general phone number, a call number between terminals may be set after being replaced with a phone number mapped to the speed dial number by the speed dial manager 480 described below. In addition, when the exchange operates as the receiving side exchange 150, if the call number corresponds to the call allow list, the call setting function between terminals may be performed.

The reception permission determination unit 450 determines whether the reception number received from the origination terminal 110 corresponds to the reception allowance list when the exchange operates as the origination exchange 130 and the originating subscriber is the call restriction service subscriber. It performs the function of determining.

As described above, a reception allow list according to an embodiment of the present invention refers to a list of telephone numbers corresponding to a terminal capable of receiving a call of the calling terminal 110. In addition, when the received number is a shortcut number, the reception allow list may include a shortcut number list.

When the receiving subscriber is the call restriction service subscriber, the call permission determining unit 460 determines whether the telephone number corresponding to the calling terminal 110 corresponds to the call allow list.

The call permission list refers to a list of phone numbers that can be set up by the receiving terminal 180. Of course, it is obvious that the transmission allow list according to the present invention can be changed at any time.

The message manager 470 transmits a call impossible guide message to the calling terminal 110 when the received number does not correspond to the allow list or the calling number does not correspond to the allow list. The announcement message may be transmitted via an ARS server which is a voice message server. In addition, according to an embodiment, the guide message may be a message generated and transmitted by the exchange.

The speed dial number management unit 480 maps a received number to a call number for a call connection when the received number included in the call received from the calling terminal 110 is a speed dial number and the speed dial number exists in the reception allow list. Replaces the phone number with the old one.

Not all components of the exchange shown in FIG. 4 need to be implemented in hardware form, and some components (eg, subscriber information inquiry unit 420, service subscription determination unit 430, etc.) may not be implemented. It is obvious that the form may be implemented.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention. Additions should be considered to be within the scope of the following claims.
