Apparatus and Method for Assignment of Unique Telephone Number in a Private Branch Exchange}

The present invention relates to assigning a user's own telephone number for a mobile telephone to which a specific telephone number is not assigned in a private exchange. Specifically, a user who is registered with the exchange through a floating telephone that is not fixed to a specific telephone number. The present invention relates to an apparatus and method for allocating a unique telephone number in a private exchange to assign and use a unique telephone number of a corresponding subscriber to a corresponding telephone when a user logs on.

Generally, in a private exchange, a telephone at a specific location is assigned a specific telephone number assigned by the private exchange manager so that the new user uses the telephone number assigned to the telephone at the specific location even if the user changes.

That is, a telephone number is not assigned to each user who is registered at the exchange and uses the telephone, but is assigned to each telephone at a specific location.

Therefore, in the case of offices with a large number of out-of-office offices (eg, sales, after-sales service, insurance companies, etc.), it is inefficient to assign a specific telephone number to a telephone at a specific location, especially if there is a shift. You should tell people who know your existing phone number as their phone number.

In the conventional telephone number assignment process, as shown in FIG. 1, when a telephone is hypothesized at a specific position in the private switching system (S11), the telephone is assigned a specific telephone number by the system administrator (S12).

Then, the telephone user makes an incoming / outgoing call using a specific telephone number assigned by the system administrator (S13).

As described above, according to the conventional phone number assignment method, there is an inefficient problem when a phone number is assigned to each phone, not a subscriber, and the subscriber is changed or the subscriber flow is large.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to allocate a unique phone number for each user in a private exchange, and to log on a corresponding subscriber to the corresponding phone when the user logs on through a floating phone that is not fixed to a specific phone number. It is to assign and use unique telephone number of.

2 is a block diagram illustrating an apparatus for allocating a unique telephone number in a private exchange according to an embodiment of the present invention.

Referring to FIG. 2, the apparatus for allocating a unique phone number in a private exchange includes an extension manager 210, a call processor 220, and a database management system (DBMS) 230.

The extension manager 210 monitors the state of the extension telephone connected to the private exchange 200 per port, detects the call of the corresponding telephone for assigning a phone number, and transmits the call to the call processor 220.

When the call processor 220 detects the call of the extension telephone by the extension manager 210, the call processor 220 interoperates with the DBMS 230 to check whether a specific telephone number of a specific user is assigned to the corresponding telephone, and then according to the check result. If a telephone number is already assigned, the telephone emits a dial tone to the extension telephone. If the telephone number is not assigned, the voice message is prepared for assigning a unique telephone number.

The DBMS 230 includes a user information table 231, a port information table 232, and a control unit 233. The user information table 231 identifies a user for each user who uses an extension telephone by joining a private exchange system. Information such as user ID and password, unique telephone number assigned to the user, user class and other function registration information are stored.

The port information table 232 stores identification information of a corresponding telephone user, a unique telephone number, user class, call forwarding information, and wakeup information for each port connected to the telephone.

The control unit 233 manages the user information table 231 and the port information table 232. When an arbitrary user requests to assign a unique phone number from an arbitrary phone, the control unit 233 stores the corresponding user information in the user information table 231. After the search, the searched user information and the usage time information that the user wants to use the phone are registered in the port connected to the corresponding phone in the port information table 232 to allocate the information of the corresponding user.

The unique telephone number assignment device of the above configuration basically does not assign a telephone number to a telephone at a specific location, but a user who has been assigned a unique telephone number corresponding to his or her ID by an administrator of a private switching system. If you want to use it, register the phone number assigned to the user to the port to which the specific phone is connected.

Hereinafter, the operation of the unique phone number assignment apparatus of the present invention will be described in detail with reference to FIG. 3.

Basically, the user information table 231 of the DBMS 230 stores user information such as user IDs and passwords of the extension telephone users, telephone numbers, and other additional service requests.

Thereafter, when any user picks up the receiver, the extension manager 210 detects the call of the corresponding telephone and transmits the call to the call processor 220 (S31).

Accordingly, the call processing unit 220 checks whether or not a unique phone number of another user is already assigned to the corresponding phone in cooperation with the DBMS 230 (S32).

That is, the call processing unit 220 inquires whether the corresponding phone is assigned to the other user's unique phone number to the DBMS 230, and the control unit 233 of the DBMS 230 searches the port information table 232 User information of another user is registered in the port to which the corresponding phone is connected and checks whether a unique phone number of the corresponding user is assigned and responds to the call processor 220.

As a result of the check, if the corresponding phone is already registered with another user's unique phone number, the call processing unit 220 transmits the dial tone to the corresponding phone through the extension management unit (S33), and if not registered, prepares to assign a phone number. The voice message is transmitted (S34).

Then, when the user who listened to the phone number assignment voice message is input by the telephone number assignment function code for assigning the user's unique telephone number, the user ID and the user identification information, the user ID and the password, and the telephone usage time information in sequence (S35). The call processing unit 220 detects this through the extension management unit 210 and delivers it to the DBMS 230.

Then, the control unit 233 of the DBMS 230 retrieves the corresponding user information stored in the user information table 231 by using the user identification information input through the call processing unit 220, and uses the retrieved user information in use time information. In addition, by registering to the corresponding port of the port information table 232, that is, the port connected to the phone that the user wants to use as his own phone number, the user assigns the user's unique phone number to the corresponding phone and then receives a corresponding allocation completion signal. It transmits to the call processing unit 220 (S36).

When receiving the unique telephone number assignment completion signal, the call processing unit 220 transmits the telephone number allocation completion tone to the corresponding telephone through the extension manager 210 (S37).

As described above, when a specific telephone number of a specific user is assigned to the extension telephone, the user may make and receive calls through the telephone with his / her own telephone number for the registered usage time.

Then, when the phone usage time registered in the corresponding port expires, registration is automatically canceled, and even before the time expires, the user can delete his / her phone number registration by using the function deletion code.

On the other hand, when a telephone number not logged on is received, the call forwarding function or the missed call function is activated .

In addition, the embodiment according to the present invention is not limited to the above description, and various alternatives, modifications, and changes can be made within the scope apparent to those skilled in the art.

As described above, the present invention by assigning a unique telephone number for each user in the private exchange, when the user is logged on through a mobile phone that is not fixed to a specific telephone number by assigning the subscriber's unique telephone number to the telephone For example, not only can private exchange subscribers use the phone more conveniently, but also more users are using the phone than the phone, and users are more mobile and can use the phone more efficiently in offices that do not require a fixed seat .
