As shown in Figure 1, the additional number service service system according to an embodiment of the present invention,

A customer information manager 20 for storing personal information of a subscriber of an additional telephone number service which gives an additional telephone number in addition to the basic telephone number;

The customer information management unit 20 receives the input information of whether or not the additional telephone number service subscription of the telephone number, and when the call is received by the additional telephone number of the service subscriber, by connecting the call to the basic telephone number added from the subscriber An additional telephone number service unit 60 which receives input of a call for a telephone number and connects a call or a voice mail accordingly; And

And an exchange unit 70 for connecting a signal received to a corresponding telephone number according to a control signal of the additional telephone number service unit 60.

FIG. 2 is a detailed view of the additional telephone number service unit of FIG.

2, the above-mentioned additional telephone number service unit 60,

A subscriber database 67 for receiving and storing information on whether to subscribe to an additional phone number service of the corresponding phone number from the customer information management unit 20;

A subscriber control section 66 for searching the subscriber database 67;

When a call is received from the subscriber's additional telephone number, the subscriber can search whether the subscriber subscribes to the additional telephone number service of the corresponding telephone number. Call processing unit 65 for receiving whether or not, and controls to connect the call or voicemail accordingly;

A relay line device (61) for interfacing the input / output signals of the switch and the call processing unit (65);

A voice guidance device 63 for providing voice guidance to the subscriber;

A signal message processing unit 62 for processing the signal message; And

Tone and Dual Tone Multiple Frequency (DTMF) reception / supply unit 64.

Then, the operation of the additional number service service system according to an embodiment of the present invention having such a configuration will be described in detail with reference to FIGS. 1 to 3.

3 is an operation flowchart of a method for providing an additional phone number according to an embodiment of the present invention.

First, the mobile subscriber subscribes to an operator to use an additional telephone number service.

In this state, when an arbitrary caller makes a call using the supplemental telephone number as the called number, the caller to the supplemental telephone number service unit 60 is routed through the route of the base station 71 , the base station controller 72, and the exchange 73. It is connected (S10).

Then, the call processing unit 6 5 of the additional telephone number service unit 60 having received the service request for the additional telephone number from the relay line device 61 and the signal message processing unit 62 sends the additional telephone number to the subscriber control unit 66. Request inquiry / search for (S20).

The subscriber controller 66 searches the subscriber database 67 to find out whether the corresponding additional telephone number exists (S30).

If the additional phone number does not exist, the subscriber controller 66 notifies the call processor 65 that the subscriber does not exist, and the call processor, which has received a database search result for the non-subscriber, transmits an announcement for it. Request to the voice guidance device 63.

Then, the voice guide device 63 transmits a comment that the phone number is missing through the route of the relay line device 61, the switchboard 73, the base station controller 72, and the base station 71 (S40).

On the other hand, if the additional telephone number exists, the subscriber control section 66 searches in the subscriber database 67 whether the additional telephone number user has allowed call reception (S50).

As a result of the search, when voicemail connection or incoming call is not allowed, the call processing unit 65 connects the call to the voicemail system 10 through the signal message processing unit 62, the relay line device 61, and the exchange 71. (S60).

Voicemail system 10 then guides the subscriber to store the desired message.

On the other hand, if the call is in the allowed state, the call processing unit 65 receives the actual called number for the additional telephone number from the subscriber control unit 66, and the tone DTMF to the calling party via the signal message processing unit 62 and the relay line device 61. The ring back tone of the supply receiving device 64 is provided to indicate that the call is being connected (S70). At this point, the caller will hear the ring back tone.

In addition, the call processing unit 65 receives the incoming call setting request using the actual called number through the signal message processing unit 62 and the relay line device 61 at the same time as the ring back tone connection processing (S80).

Then, the exchange 73 transmits a signal to the terminal 1 via the route of the base station controller 72 → base station 71, and when the called subscriber responds (S90), the response signal is transmitted to the base station 71. Transmitted from the signal message processor 62 to the call processor 65 via the route of the base station controller 72 → the switch 73.

Then, the call processing unit 65 transmits the voice message to the subscriber through the voice processing device 63, "The call is received through the additional telephone number. If you do not want to call 1, please press 2". (S100). Here, the tone and the DTMF receiver 64 may be used instead of the voice announcement to transmit a special tone for 2-3 seconds.

After that, the subscriber knows that the call is an additional phone number and wants to receive it by entering '1' or listening to the announcement until the end (S110), if there is no response (S110), the call is determined to be allowed and the call processor 65 is internal. The sender and the called subscriber are connected by using the bus (S150).

On the other hand, if the incoming subscriber knows that the call is an additional phone number and do not want to receive it, enter '2' (S130) or terminate the corresponding call during the announcement (S140). 65 allows the caller to be connected to the voicemail system 10 through the signal message processing unit 62 , the relay line device 61, and the exchanger 73 (S160).

The caller then stores the desired content in the voice mailbox system 10 and ends the call.

Embodiments of the present invention as described above can be variously modified, can be used as many additional phone numbers as needed, can be selectively received.

The invention is not limited to mobile phones, but can be used for other mobile communication devices capable of two-way wireless communication.

 As described above, in the embodiment of the present invention, by providing a service to selectively receive a call to the additional telephone number, the service provider can provide a high quality service to the user.
