The national exchange is the central nerve of the national telecommunication, which is installed to provide the convenience of the whole nation, and the user is intended for the national. The private exchange or the application communication system serves the subscribers of the single station, the lowest station of the public telecommunication network. .

Private exchanges are used mainly in places where there are many inter-extension business contacts such as hotels, department stores, government offices, and large corporations.

Private exchanges provide automatic call distribution, conference calls, nightly transmissions of emergency calls, data services, and mail services in addition to the normal switched access functions.

As described above, a private exchange is used to exchange and connect a subscriber so that mutual call between subscribers is possible.

In addition, private exchanges are provided to support wired communication services in the premises and provide wired communication and mobile communication (wireless) services in the premises.

1 is a diagram illustrating a phone number assignment structure for wireline subscribers in a conventional private exchange.

In the conventional private exchange, the telephone number assignment to the wired subscriber is performed by the operation of the system administrator, not the subscriber, to allocate the telephone number to one terminal as shown in FIG.

First, the system administrator accepts the subscriber's request and executes the operation management program in the operation administration (OAM) monitor unit 1 and selects a menu for adding / changing / deleting a phone number. When the system administrator assigns a phone number to a specific line through a manual operation of mapping one physical line (telephone line) and a phone number in the operation management monitor 1, this information is converted into a message and the operation management unit Is sent to (2).

The operation management unit 2 checks the validity of the telephone number and records it in the database 3 if valid.

At this time, the database 3 manages all of the subscriber's information.

When such a conventional private exchange performs call processing of the wired terminal 8 and the wired terminal subscriber, first, when a signal arrives at the call processing unit 5 via the subscriber processing unit 7 or the switching unit 6, the call is processed. The processor 5 connects calls between subscribers.

At this time, the telephone number / physical line mapping unit 4 finds the physical line of the called party by referring to the telephone number table of the database 3 when the call is received.

In the conventional private exchange, the telephone number assignment for the wired subscriber is to assign only one telephone number to one terminal, and in some cases, assigns several telephone numbers to one terminal. The management monitor unit 1 executes.

In order to implement the wired / wireless combined function in the conventional private exchange, as shown in FIG. 2, when a call occurs in the wired / wireless terminals 11 and 12, the generated call is transferred by the wired / wireless subscriber processing unit 13 or 14 to the wired / wireless subscriber call processing unit. (16) (17).

At this time, when the generated call is connected to the wired subscriber call processing unit 16, the wired subscriber call processing unit 16 connects an incoming signal between wired subscribers or an incoming signal with a wireless subscriber.

When the generated call is connected to the wireless subscriber call processing unit 17, the wireless subscriber call processing unit 17 connects an originating signal to the wireless subscriber or the wired subscriber.

At this time, the wireless subscriber handoff unit 18 guarantees mobile communication by the wireless subscriber.

The authentication processing unit 19 then checks the authentication validity of the wireless terminal.

Then, the database 20 and the telephone number / physical line mapping unit 21 locate the called party physical line using the telephone number table of the database 20 when the call is received.

4A shows how the location registration of the wireless subscriber is performed, and FIG. 4B shows how the authentication procedure of the wireless subscriber is performed.

The wired subscriber only connects to the corresponding line and does not perform a location registration process like the wireless subscriber.

In the wired and wireless systems in the conventional private exchange, there are the following problems.

first. Only one telephone number is assigned to one physical line, and when multiple telephone numbers are assigned, subscribers cannot directly assign, change, or delete telephone numbers, and thus cannot change information in real time.

Second, the mobility of the wire is not guaranteed. In other words, call forwarding can be used to guarantee limited mobility. However, call forwarding is restricted to forwarding to another subscriber.

Third, in order to provide wired / wireless functions in one system, different structures are used. Therefore, a system for connecting a wired subscriber to a wireless subscriber should be separately provided.

The signal processor 26 analyzes the message and transmits the message to the telephone number input unit 28 as in the authentication procedure.

The telephone number input unit 28 checks whether the telephone number transmitted in the message is valid, and if so, registers this information in the database 30. At this time, the database is composed of the connection structure of the terminal authentication number / phone number / physical line. That is, it should be possible to find the authentication number and the physical line of the terminal using the telephone number. In this case, several telephone numbers may be registered in one terminal at a specific moment. In other words, from the point of view of a private exchange system, multiple telephone numbers are assigned to one physical line.

At this time, when one location registration process is performed, the telephone number assigned to the existing physical line is lost. Functionally, multiple phone numbers can be registered in one terminal, so that several people can use one terminal in common, and one person can make a call for an incoming call using several telephone numbers.

In addition, if a different ring tone is generated for a different phone number in the terminal, even if several people use a single terminal, the incoming call can be easily distinguished, and the phone number display unit is provided on the terminal to easily display the incoming phone number. Can be distinguished.
