Description

How to Automatically Subscribe Digital Phones in Exchanges

1 is a system diagram for realizing the present invention.

2 is a flow chart in accordance with the present invention.

The present invention relates to an automatic direct subscription method of a digital telephone in an exchange.

Notify the operator to register the digital telephone subscriber to the switch as shown in FIG. The operator identified the tracks that could be assigned at the exchange, and made the registration by changing the database directly by the exchanged user so that the subscriber could register the digital telephone subscriber.

That is, the digital subscriber 10 contacts the operator and, upon request for registration of the digital subscriber 10, searches for the digital port in the free state at the switchboard and registers the subscriber with a database change at the switchboard. After the switchboard notifies the digital subscriber 10 of the registration, the digital subscriber 10 receives the service of the switchboard and completes the registration as a normal subscriber.

As a result, a digital telephone would need to perform unnecessary manual switchboards (search and registration procedures) in order to register at the switchboard, and the digital subscriber would have to make his / her phone number and wait until registration with a meaningless time wasted during registration. .

Accordingly, it is an object of the present invention to provide a method in which a subscriber can subscribe directly alone without assistance of a switchboard, thereby improving the service efficiency of the switchboard.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an exchange that becomes a node in a switching network, and includes a subscriber unit 10, a subscriber circuit 20 for controlling a subscriber, a central processing unit 30 for controlling a switching system, and the central processing unit 10. And a switching circuit 40 for switching voice information and signaling information through internal and trunk line interfacing, and a tone source circuit 50 for generating various tone signals.

In the present invention, when the subscriber 10 tries to join the exchange, the subscriber circuit 20 receives the subscription id and sends it to the central processing unit 30. In the central processing unit 30, the permission tone to be subscribed to, that is, the tone source 50 is operated by the switching circuit 40 to attach the permission tone to the subscriber 10. The subscriber 10 who hears the permission tones hits a personal code. Then, the subscriber circuit 20 sends the personal code to the central processing unit 30, the central processing unit 30 analyzes it and sends a tone to the subscriber in the same way when the personal code is correct. When the subscriber 10 dials the phone number to be used by the subscriber 10, the subscriber circuit 20 sends it to the central processing unit 30, and the central processing unit 30 receiving the same receives a registration (registration) when the same personal code is not present in the magnetic exchange. The tone to be completed is transmitted to the subscriber through the switching circuit.

Therefore, when a specific embodiment of the present invention is described in detail with reference to FIGS. 1 to 2, in step 101, if any subscriber hooks off, it is determined whether the subscriber is registered in the exchange in step 102. .

If the subscriber is a registered subscriber, go to step 103 and generally receive the service of the exchange, otherwise, send the transmission mode to send the digital telephone mode through the subscriber circuit 20 to the digital telephone, and put the exchange system into the mode scan state. Stay. In step 105, when the first second mode from the digital telephone comes to the central processing unit 30 through the subscriber circuit, the central processing unit 30 stores the mode, and in step 106 the NU is stored through the subscriber circuit 20. The message (Not USE) is sent to the subscriber unit 10. In this case, the digital phone receives "NU" and attaches NU TONE to the subscriber.

The subscriber who hears the NU tone decides that he or she may register, and in step 107, after the NU is sent, the exchange sends a message to the digital telephone through the subscriber circuit 20 to the digital telephone, which is an indication of permission to digitize, It plays an important role in making the digit count of the subscriber circuit 20 equal to "0", and the subscriber circuit 20 prepares to receive a digit. The subscriber digits and transmits the digit at step 108 in the subscriber circuit 20 to the receiving central processing unit 30. When receiving the digit, the subscriber receives the second digit at step 109 to receive the central processing unit 30. When sending to the central processing unit 30 performs a digit reception analysis (step 202), and if it is determined to perform the digit function to determine the subscriber registration id in step (204) to go to step (206) otherwise If it is determined to be a digit, step 203 is performed in which a message " NU " is sent to the digital telephone, and step 205 clears the subscriber information so far.

In step 203, the digital telephone adds a busy tone to the subscriber. In step 205, the central processing unit 30 sends the CCN32 signal through the subscriber circuit 20 to the subscriber unit 10 at the transmission rate " 32 Kbps ", and in step 207 the CCA recognizes that the message CCN32 has been received. Send it. Then, in step 208, the central processing unit 30 sends a message to the subscriber through the subscriber circuit 20, and attaches a time of 40 msec to the subscriber, which is the only message forward when two messages are sent at the same time. Loss cases often occur with time delays. When a time out occurs in step 209, the central processing unit 30 transmits a message called a transmit digit to the subscriber 10 through the subscriber circuit 20 and sets the digit count value to be received to “0”. Clear it. After that, in step 301, when the subscriber unit 10 sends the personal code to the CPU 30 through the subscriber circuit 20, is the personal mode correct? If it is determined by the central control unit 30 is wrong and sends the NU to the subscriber 10 via the subscriber circuit (20). The digital telephone receiving the NU informs the subscriber in step 304 that it is not registered in the busy tone.

Otherwise, the same operations are performed in steps 205 to 209 as in step 205 (steps 305 to 308). In step 309, the subscriber sends the digits from the digital telephone 10 to the central processing unit 30 through the subscriber circuit 20. In step 401, the central processing unit 10 checks whether the telephone number to be registered by the subscriber 10 is a telephone number used in the own exchange. You will be asked if you have a phone number. If a recognition signal is received, and sends a "NU" to the subscriber unit 10 through the subscriber circuit 20 in step 402, which serves to connect the busy tone to the subscriber that the subscriber is not subscribed.

After step 403, the central processing unit 30 clears the information of the subscriber unit 10 to be subscribed to. Step 404 is a routine in which the CPU 30 determines that there is no identical telephone number and again compares whether or not the personal code of step 405 is the same. In step 406, if the PC is the same, the subscriber 10 dials. This is a message indicating that the subscriber is not subscribed and the subscriber is told busy tone on the digital telephone. So step 408 is the central processing unit 20 sends a message that the registration is completed to the subscriber 10 via the subscriber circuit 20. The digital phone receiving this gives the subscriber a ton of good registration. In addition, since the exchange is registered in step 409, whether or not to make or end a call, the central processing unit 30 receives a digit to be received as a routine for processing the next event (ie, subscriber behavior). ", And prepare to receive a digit. This step 410 indicates that the registration is completed, the subscriber can directly join the switching network can be said that the service of the exchange for the subscriber is further improved.

As described above, subscribers can sign up without assistance from the switchboard, which improves the service efficiency of the switchboard, and digital subscribers can also register digital subscribers as they can register subscribers, which only analog subscribers can do. There is an advantage that can be performed just like an analog subscriber.
