JPS5970069A - Method for releasing registration in virtual terminal communication system - Google Patents

Abstract

PURPOSE:To make a subscriber set up the active time simultaneously with the registration of the subscriber, to prevent a card as an input medium from being stolen and to release the registration effectively by providing the titled system with a means setting up active time length in a terminal receiving registration at the same time as the registration and a clock means. CONSTITUTION:The subscriber 1 inputs the subscriber's No. from a subscriber's No. input terminal 3 to a terminal equipment 13 through an input/output circuit 5 by an input medium 2, and simultaneously inputs the registration active time from a registration active time length input terminal 4. Subsequently, the medium 2 is returned to the subscriber and the circuit 5 forms information obtained by adding a terminal No. to the subsriber's No. and transfers the information to a home memory 14 on the exchange side. The circuit 5 sends the information of the active time length to a counter 7, which counts up clock pulses 6 and transfers the counted information to a controlling circuit 8. The controlling circuit 8 detects the reach of the active time length on the basis of the active time length and the counted information and sends reset information to the counter 7 to release the registration.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a subscriber number deregistration method in a virtual terminal communication system.

Here, the outline of the virtual terminal communication method will be explained as follows.

Generally, a subscriber number and, for example, a telephone number of a subscriber's telephone as a communication terminal are synonymous and given the same number since the telephone is owned by the subscriber. However, in the virtual terminal communication system, the subscriber number is a number assigned to an individual subscriber, and a communication terminal such as a telephone has a
A unique number is assigned to the terminal, and as a result, the subscriber number and the communication terminal number are distinguished from each other as independent numbers. When a subscriber with a subscriber number of (This is called home memory) in advance. Thereafter, communications addressed to the subscriber number arriving at the switching center will be connected to the registered terminal. In this way, a subscriber can communicate using any terminal after registering for the first time.

Such a virtual terminal communication system has already been proposed in Japanese Patent Application No. 57-475.
A patent application has been filed as No. 83.

Now, when registering a subscriber number in such a virtual terminal communication system, as mentioned above, the subscriber inputs the subscriber number via the terminal that has the number that the subscriber wants to associate with the registered number. It becomes necessary. Of course, the terminal is provided with means for accepting this input.

For example, if a contact type medium such as a card with a subscriber number written on it is used as an input medium for registration, and the card is inserted into a designated opening of a terminal device and a large number of inputs are made, the card may be left in the terminal device. If you do so, there is a risk of theft. Furthermore, in a system where the subscriber is required to cancel the registration when he or she leaves the registered terminal, there is a possibility that the subscriber may become depressed and leave without remembering to cancel the registration.

The present invention has been made in order to eliminate the inconvenient circumstances in the prior art as described above.Therefore, an object of the present invention is to eliminate the risk of theft of a card as an input medium,
Another object of the present invention is to provide a ``registration cancellation method'' in a virtual terminal communication system in which there is no fear of forgetting to cancel registration.

The main point of the configuration of the present invention is that in a virtual terminal communication system, the terminal side that accepts registration is provided with means for setting the effective time length and timekeeping means at the same time as the registration, and the subscriber can register the subscriber number at the same time. The valid time length is set, and when the terminal side detects that the valid time length has elapsed by a clock means, it sends a signal to the memory to cancel the registration.

Next, an embodiment of the present invention will be described with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention.

In the figure, 1 is a subscriber, 2 is an input medium such as a card,
3 is a subscriber number input terminal, specifically a device for reading information recorded on an input medium; 4 is an input terminal for valid registration time; specifically, a device such as a keyboard; 5 is a subscriber number and a device such as a keyboard; An input device (not shown) for inputting information about the effective time length
6 is a clock pulse, 7 is an input/output circuit for receiving and receiving between
is a counter, 8 is a control circuit that sets the Fi registration valid time length and controls the counter, 9 is an input/output circuit 5 and a control circuit 80
10 is a data line between the input/output circuit 5 and the counter 7; 11 is a transmission line for transferring the subscriber number and registration valid time length to the Baum memory 14; 12 is a data line between the control circuit 8 and the counter 7; 13 is a terminal, and 14 is a home memory.

Next, the operation will be explained. The subscriber 1 manually inputs the subscriber number from the input terminal 3 to the terminal 13 via the input/output circuit 5 using the input medium 2, and similarly inputs the registration valid time length from the input terminal 4, which is a keyboard or the like. do. Immediately thereafter, the input medium 2 is returned to the subscriber 1. The input/output circuit 5 generates information by adding the terminal number to the input subscriber number 9, and transfers the data to the home memory 14 on the exchange side. Further, the input/output circuit 5Fi transfers information regarding the registered valid time length to the control circuit 8, and information for starting counting to the counter 7. The counter 7 starts counting clock pulses 6 based on count start information (set information) from the input/output circuit 5, and sends information about the number of pulses counted to the control circuit 8. The control circuit 8 compares the information from the counter 7 with the information on the number of pulses to be counted corresponding to the registered valid time length, and when it is detected that the registered valid time length has been reached, it outputs information to stop the counter 7. (Reset information) is sent to the counter 7, and information that the registered valid time length has been reached is sent to the input/output' circuit 5. The counter 7 stops counting the pulses, and the input/output circuit 5 stores the information in the home memory 14 from the terminal 13 of the subscriber 1.
Transfer information to cancel the registration of the correspondence relationship. If a timer function is added to the input medium 2, it is possible to notify the subscriber that the registration valid time length has been reached through sound, vibration 9, etc. This allows the subscriber to re-register if necessary. can be done.

As explained above, if the registration cancellation method of the present invention is used, the input medium is returned to the subscriber immediately after the subscriber inputs the subscriber number and registration valid time length into the terminal, so there is no need to misplace the input medium. It is possible to prevent theft, and since the registration is not made for a period longer than the valid registration time, forgetting to cancel the registration can also be prevented.
