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

4 to 7 are tables of information on whether an incoming call is stored in a subscriber database in the extension telephone number service device according to the embodiment of the present invention.

First, when a mobile subscriber subscribes to an operator to use an additional telephone number service, the mobile telephone subscriber sets a permission for the additional telephone number according to his preference. Of course, modifications can also be made arbitrarily. The present invention allows a service subscriber to input, change, and delete information in an interactive voice response (IRR) or automatic response system (ARS) for inputting information of a corresponding subscriber on a call permission condition.

In more detail, the subscriber may preset the caller's condition and connect only the caller's call that meets the condition. The conditions here can be set as needed. The method can be checked by a password, a method of searching for and determining whether it is in the list of calling numbers, the method of determining according to the calling party's station number, and the calling area or operator's number. Method and the like. You can also decide by time of day. These methods can be parallel or add any number of other conditions.

In addition, as shown in FIG. 4, a database can be set to set incoming call permitting conditions and whether or not to input a password according to the subscriber.

In this state, when an arbitrary caller makes a call using the additional telephone number as the called number, the call is sent to the additional telephone number service unit 60 through the route of the base station 71, the base station controller 72, and the exchange 73. Connected.

Then, the call processing unit 65 of the additional telephone number service unit 60 that receives the service request for the additional telephone number from the relay line device 61 and the signal message processing unit 62 sends the subscriber control unit 66 to the additional telephone number. Request the search / search for (S301).

The subscriber controller 66 searches the subscriber database 67 to find out whether the corresponding additional telephone number exists (S302).

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 telephone number is missing through the call route of the relay line device 61, the switchboard 73, the base station controller 72, and the base station 71 (S330).

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 the incoming call (S303).

As a result of the search, if the voicemail connection or the subscriber has allowed INHIBIT, the call processing unit 65 performs the voicemail system 10 through the signal message processing unit 62, the relay line device 61, and the exchange 71. To be connected to the call (S304).

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

In addition, if the subscriber has allowed (ALLOW) to connect the call to the actual called number (S305).

On the other hand, if the allowable condition is an allowable condition according to the condition (CONDITION), the incoming call permitting condition is searched (S306).

If the condition (CONDITION) is AREA, as shown in the table of Fig. 5, the calling party's calling number is compared with reference to the allowed operator list for each subscriber (S313).

The comparison result (S314), if the calling number is the allowed operator's station number, the call is connected to the actual called number (S315), and if the calling number is not the allowed operator's station number, the caller connects the call to the voice mailbox system 10 To leave a message (S326).

If the condition (CONDITION) is PREFIX, as shown in the table of Fig. 6, by comparing the station number of the calling party's caller number with reference to the allowed station number list for each subscriber (S319, S320), if it matches, it is determined that the call is allowed. Connect the call to the called number (S321), if the station number of the calling number does not match the allowed station number, the call to the voice mailbox system 10 to allow the caller to leave a message (S326).

In addition, if the condition (CONDITION) is LIST, as shown in the table of Figure 7, by comparing the calling party's caller number with reference to the subscriber's allowed number list (S322, S327), if the match is determined to allow the call actually The call is connected to the called number (S328), and if the caller ID does not match the allowed number, the call is connected to the voice mailbox system 10 to allow the caller to leave a message (S326).

If the CONDITION is PASSWORD, the caller is required to enter a password (S323, S324), and if the password matches, the call is determined to be allowed and the call is connected to the actual destination number (S325). The call is connected to the system 10 to allow the caller to leave a message (S326).

On the other hand, if the condition (CONDITION) is ALL, referring to the table of Figs. 4 to 7, the subscriber-allowed operator, station number, permission number and password are sequentially searched.

That is, first, as shown in the table of Figure 5, by comparing the caller's caller number with reference to the list of allowed operators by subscriber (S307, S308), the comparison result, if the caller's station number of the allowed operator, the actual called number Connect the call to (S310), and if the caller ID is not the allowed operator's station number, as shown in the table of Figure 6, the station number of the caller's caller number is compared with reference to the subscriber's allowed station number list (S309).

Next, in the comparison result (S311), if the station number of the allowed station number list by subscriber and the station number of the caller's caller ID match, determine the call allowed to connect the call to the actual destination number (S310), and the station number of the caller ID is allowed. If it does not match, as shown in the table of Fig. 7, the calling party's calling number is compared with reference to the subscriber's allowed number list (S316).

If there is a caller's calling number in the subscriber's allowed number list, that is, if it matches, the call is determined to be allowed and the call is connected to the actual called number (S310). If the password matches (S317, S318), it is determined that the call is allowed and the call is connected to the actual called number (S310). If the password is not matched, the caller connects the call to the voice mailbox system 10 to send the message. To leave (S326).

The above conditions can be changed and serviced by the operator or subscriber as necessary, and there are various modifications.

In addition, multiple additional telephone numbers may be used as necessary.

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 according to the caller's conditions, the service provider can provide a high quality service to the user.
