As shown in FIG. 3, the outgoing call control device 300 according to an embodiment of the present invention includes a receiver 310, a controller 330, a transmitter 370, and may further include a database 350. Can be. As the originating call control device, a centrix server may be used, but is not limited to the present embodiment.

The receiving unit 310 receives a call setup request signal from the calling terminal having the first identification information to the called terminal transmitted through the wireless network. In this case, the calling terminal may be the calling terminal of the subscriber, and the call setup request signal received from the calling terminal of the subscriber may be a digital signal.

The control unit 330 obtains subscriber information of the calling terminal, and obtains second identification information of the calling terminal subscriber from the subscriber information. In this case, the second identification information of the calling terminal subscriber may be a wired telephone number. For example, assuming that a subscriber has previously registered a mobile phone number and a landline phone number, and has made a call to any terminal A by a mobile phone, the receiving unit 310 receives a call setup request signal to the terminal A, and the control unit 330 Obtains the landline telephone number which is the second identification information of the subscriber.

Here, the subscriber information of the calling terminal subscriber may be stored in the database 350, in which case the controller 330 obtains the subscriber information from the database 350.

The transmitter 370 transmits the second identification information and the call setup request signal to the called terminal. In this case, the second identification information may be transmitted in a field form in the call establishment request signal, and the transmission form is not limited. Since the transmitting unit 370 transmits the call setup request signal together with the second identification information, the called terminal receives the call setup request signal together with the second identification information. As a result, the called terminal receives the second identification information by the calling party number. Will be displayed. For example, a terminal set up with a call with a certain terminal A substantially transmits a call setup request signal including a wired telephone number or a wired telephone number from a subscriber's mobile phone or originating call control device 300, and thus, a called terminal. In A, the landline telephone number is displayed as the calling party number.

4 is a block diagram of an incoming call control device according to an embodiment of the present invention.

As shown in FIG. 4, the incoming call control device 400 according to an embodiment of the present invention includes a receiver 410, a controller 430, a transmitter 470, and further includes a database 450. Can be. As an incoming call control device, a centrix server may be used, but is not limited to this embodiment.

The receiving unit 410 receives a call setup request signal from the calling terminal to the called terminal having the third identification information. At this time, the originating terminal means any originating terminal requesting call setup to the called terminal of the subscriber. And the third identification information may be a landline telephone number.

The receiving unit 410 receives a call setup request signal transmitted by a caller to a called terminal having third identification information. In this case, the call setup request signal may be a signal directly received from the caller terminal. It may be a signal received through the. For example, if the called terminal having the third identification information is an analog terminal, it will go through an electronic switch close to the analog terminal to transmit a signal to the analog terminal. As an example, when a signal is input to the electronic exchange, it may be set to automatically forward the call to a VoIP number or a census number corresponding to the analog terminal. The call setup request signal to the VoIP number or the centric number is transmitted to the receiver 410 of the incoming call control device 400 through the wired / wireless communication network. In another embodiment, the signal input to the electronic exchange may be set in advance to be directly transmitted to the incoming call control device 230.

The control unit 430 obtains subscriber information of the called terminal, and obtains fourth identification information of the called terminal subscriber from the subscriber information. In this case, the subscriber information may be stored in the database 450, in which case the controller 430 obtains the subscriber information from the database 450. In this case, the fourth identification information may include one or more wired or wireless identification information. The fourth identification information includes not only the identification information of the terminal in the subscriber's name, but also the identification information of the subscriber and the identification information of another terminal set in one group. That is, the names of one or more wired / wireless terminals need not be all subscribers. If identification information such as VoIP number of another terminal is registered in the subscriber information, the controller 430 recognizes it as one of the fourth identification information of the subscriber. can do.

The subscriber information may include the acquisition time limit for the fourth identification information as well as the fourth identification information of the called terminal subscriber. The acquisition time limit for the fourth identification information is a time preset by the subscriber, and is a constant time for which acquisition of the fourth identification information is restricted. For example, when any calling terminal B calls the subscriber's landline telephone number, the subscriber may set in advance so that other mobile phones 1 and 2 can be called. That is, the numbers of the mobile phones 1 and 2 can be viewed as the fourth identification information of the subscriber. In this case, the subscriber can set a time limit for each mobile phone. For example, the mobile phone 1 can be set not to receive calls from a landline number after 6 pm. After that, it can be set not to be called simultaneously. That is, when the acquisition time limit of the fourth identification information is included in the subscriber information, after acquiring the subscriber information, the control unit 430 compares the current acquisition time with the preset acquisition time limit, and sets only the time outside the acquisition time limit. 4 Identification information can be obtained. That is, since the incoming call control device 400 does not transmit a signal to the subscriber's other identification number at the time when the subscriber is not set up at the same time, according to the above example, only the analog terminal of the subscriber sends a call setup request signal after 11 pm. Will receive.

The transmitter 470 transmits the call setup request signal to the terminal corresponding to the fourth identification information. As described above, since the fourth identification information includes one or more wired and wireless identification information, the transmitter 470 may simultaneously transmit a call setup request signal to one or more terminals corresponding to the one or more wired and wireless identification information.

Then, the receiving unit 410, after the calling terminal is set up with the first destination terminal corresponding to the fourth identification information, in response to the call setup request signal transmitted from the transmitter 470, the first destination terminal to the call switching target, The call transfer request including the identification information of the second called terminal may be received. For example, as described above, when the mobile phone 1 and the mobile phone 1 are set to be simultaneously called, when a subscriber who owns the mobile phone 1 receives a call, a call is established between the calling terminal B and the mobile phone 1. However, if the caller terminal B is actually the parent of the subscriber who owns the mobile phone 2, the subscriber can make a call transfer during the call. There is no particular limitation on the call transfer method, and when the receiver 410 receives a call transfer request including identification information of the mobile phone 2 to be transferred, that is, the number of the mobile phone 2 or the shortcut number identified by the mobile phone 2, the transmitter 470 transmits a call setup request signal to the call switching target terminal.
