Abstract

PURPOSE:To eliminate a closed area table that is needed by a system as a whole and registering new subscribers at a single place, by setting a communication processor between an exchange and a center device and controlling totally the closed area information through the communication processor for plural center devices. CONSTITUTION:An exchange 2 storing terminals 1-1-1-N is connected to a communication processor 3, and center devices 4-1-4-M are connected to the processor 3. A control part 31 of the processor 3 searches whether or not the telephone number of a terminal is already registered on a closed area table 32 based on said telephone when said terminal gives a request of connection to a certain center device. When the relevant telephone number is registered, the bit position is read out of a display table 33 for center bit positions for the center device that desires the connection. Then it is checked whether the bit position of the corresponding terminal telephone number in the table 32 is ''1'' or ''0'' in the center information. Then the connection is secured between the terminal and the center device if the bit position is equal to ''1''. While the connection between the terminal and the center device is cut when the bit position is equal to ''0''.

Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to an information communication system in which terminals are connected to a center device via a communication switching network such as a 9-channel network or a packet network to receive desired services. The present invention relates to a management method for information indicating whether a center has joined/not joined (closed area information).

[Prior art]

In recent years, various information communication systems have been realized in which a terminal calls a desired center device via a switching network and receives a desired service. In this type of information communication system, the terminal that called the center device is the center owner. In this case, conventionally, each center device has a closed table in which the telephone number of the subscriber terminal is registered, and when a call is made from the terminal, the corresponding center device receives the telephone number from the terminal and searches the closed table.1. It was determined whether or not to accept the call depending on whether or not the telephone number of the terminal that made the call was registered. death,
In the method described in 1.1:, each center device has a closed table, so each center device has duplicate terminal phone numbers, and the total amount of memory between the center devices becomes enormous. There was a drawback.

Furthermore, when a new terminal subscribes to the communication services of a plurality of center apparatuses, there is a drawback that the terminal must be registered at each center apparatus.

[Purpose of the invention]

The purpose of the present invention is to provide closed area information management that reduces the number of closed area tables required for the entire system, prevents an increase in memory capacity, and allows registration of closed area information when a new terminal is added to a single location. The purpose is to provide a method.

[Summary of the invention]

The main point of the present invention is that in an information communication system in which a plurality of terminals are connected to a plurality of center devices via a switch, a communication processing device is placed between the switch and the center device, and closed area information for the plurality of center devices is transmitted to the communication processing device. This is to allow for centralized management.

[Embodiments of the invention]

FIG. 1 is an overall configuration diagram of an embodiment of the present invention.

In FIG. 1, an exchange 2 accommodating a plurality of terminals 1-1 to 1-N is connected to a communication processing device 3, and a plurality of center devices 4-1 to 4-M are installed in the communication processing bag W3. It is connected. Here, 1 communication processing device 3 is the center of the present invention, and 1 components related to the present invention include a control unit 31, a closed area table 32. It has a center bit position display table 33.

Figure 2 is a detailed diagram of the closed area table 32 and center bit position display table 33, where (a) is the closed area table 321b).
shows the center bit position display table 33. The closed area table 32 has the telephone number and center information for each terminal that joins the closed area. The center information associates one center device with I pino 1-, and when the value is l'', it indicates that the terminal has joined the closed area of the corresponding center device, and if it is ``o'', it indicates that the terminal has not joined. The center focus position display table 33 displays, for each center device, a center number (center ID) and bit position information indicating which bit position of the center information in the closed area table 32 the center device corresponds to. When the control unit 31 of the communication processing device 3 receives a connection request to the center device consisting of terminals, the control unit 31 uses the telephone number of the terminal as a key and checks that the telephone number has already been registered in the closed table 32. Ga nai search.

If registered, center bit position display table 33
Read the bit position of the center device to which you wish to connect, and check whether the corresponding bit position in the center information of the terminal telephone number in the closed area table 32 is It I It or '0''. If it is 111 H, the terminal/center device Establish the connection between them, and if it is LL OIt, disconnect it.

FIG. 3 is a diagram showing in detail the connection sequence between the terminal and the center device. Now, terminal 1-i (i=1.j,...
・When N) dials the telephone number of the center device 4jN=1゜2,...M)°, the exchange 2 dials the corresponding center device 4.
-j is stored in the communication processing bag W3, and the telephone number of the center device 4-j is notified. The control unit 31 of the communication processing device 3 checks whether there is any congestion or the like on its own device, and if there is no congestion, returns an affirmative (OK) response to the terminal Li via the exchange 2. When the terminal 1-i receives the positive response, it presses the start button and transmits an ENQ sequence (communication request) including its own telephone number. When the control unit 31 of the communication processing device 3 receives the ENQ sequence, it checks the closed area qualification of the terminal 1-1 using the closed area table 32 and the center bit position display table 33, and if it has joined the center device 4-1. If terminal 1-i is not subscribed, it is notified to terminal 1-i that connection to the designated center device is not possible, and the line is disconnected.

Below, conditions under which the method of the present invention shown in FIG. 1 is superior in terms of memory capacity compared to the conventional method in which each center device has a closed table will be explained.

The total amount of memory M required in the conventional method can be expressed as: M,=a-N-silkworm (1). Here, a is the amount of memory required for telephone number management, N is the number of terminals, and max is the average number of subscribed closed centers per terminal.

On the other hand, the amount of memory M required for the method of the present invention is M= (a
