Abstract

PURPOSE:To enhance the line efficiency and the operating efficiency of a system by giving priority to the first communication device which requests the communication for the second communication device under communication at present, connecting them, and storing communication requests for the second communication device other than devices under communication in a storage means. CONSTITUTION:When communication is first requested for a host A, a code (a) is stored in an opposite-side control buffer 14, and the host A can be communicated by a communication control part 8 through an exclusive line. Then, when communication is requested for a host B, a code (b) is stored in the opposite-side control buffer 14 and a connecting waiting storage part 5a, the code is selected by a connection-side selection part 6b, and the host B is connected to the switching line. Then, the code (b) is stored in an opposite-side pointer 9. When communication request from other terminals come out like hosts A, B, A, D, C..., and communication request 1b becomes like a, b, a, d, c... during communication with the hosts A and B, the requests are stored in the opposite-side control buffer 14, and the communication control part 8 makes the communication request for the host A during communication set under the connectable condition in the exclusive circuit, and the communication requirement for the host B set under connectable conditions in the switching line by giving priority to the communication request for the host A.

15b is a line control section; 16 is a network control section;
Control Unit (hereinafter referred to as NCU),
17 is a keyboard, 18 is a key input control section, 19 is a display, 20 is a display control section, 21 is a dedicated line, and 22 is a switched line.

The connection destination selection section 6b reads the connection request data stored in the connection waiting storage section 5a, and extracts the corresponding telephone number from the destination telephone number registration buffer 10. Then, data indicating which one was taken out is stored in the destination pointer 9,
It has a function of notifying the communication control unit 6 of the other party.

The communication control unit 8 can determine the connected destination hosts A, B, C, - from the contents of the destination pointer 9, so that each terminal device 1-1. 1-2. - Compare the destination management buffer 14 holding the connection request destination and the destination pointer 9, and if they are the same, the line control unit 15 and its terminal device 1-1.
1-2. Connect - and - to enable sending and receiving.

(2) If different, refer to the connection waiting storage unit 5a, and if the requesting host is already in the queue, you can leave it as is, or if not, link the request to the end of the queue.

(2) If there is no longer a request for the other party being communicated with, the connection destination selecting unit 7 is made to select the next communication requesting destination host A, B, C, -, and a connection is made to that other party.

It has this function.

A destination pointer 9 indicates the destination of communication.

The destination telephone number registration buffer 10 is the connected host) A
, B, C, - are registered.

The destination telephone number registration/update section 11 registers/updates a telephone number in the destination telephone number registration buffer 110 by inputting from the keyboard 17. The telephone number of the other party inputted from the keyboard 17 is displayed on the display 19 and registered/communicated after confirmation.

The comparison unit 12 includes the terminal device 1-1. 1-2. It has a function of comparing the communication request destination from -.- with the communication destination indicated by the destination pointer 9.

The channel control unit 13 controls the terminal device 1-1. 1-2. - It has an interface control function with.

The partner management buffer 14 stores the code of the partner currently communicating or requesting communication to the terminal device 1-1. 1-2. -・It is stored in each area.

The line control unit 15a is in charge of network connection control and data transmission and reception with host A and line control unit 15b with bosses A, B, C, -.

The NCU 16 is used when the line is a telephone line, and has the function of controlling connection and disconnection of the circuit switching network, such as calling and recovery.

The dedicated line 21 is a line used exclusively for connection to host A, which has a high frequency of communication requests.

The switched line 22 is connected to hosts B and C other than host A.

This line is used to switch to communication with -.

Since it has such a configuration and function, as shown in FIG.
1. 1-2. - When a communication request is made to host A from either of
The communication control unit 8 enables the host A to communicate via the dedicated line.

Next, when a communication request is issued to host B, code b is stored in the destination management buffer 14 and the connection waiting storage unit 5a, and
The host B is selected by the connection destination selection unit 6b and connected to the switched line. Then, code b is stored in the destination pointer 9.

The subsequent connection method for communication requests will be explained with reference to the flowchart in FIG.

During communication with hosts A and B, communication requests from other terminal devices are issued as hosts A, B, A, D, C, -, and communication request 1b has codes a, b, a, d. .

When it becomes like C9-, it is stored in the destination management buffer 14, and the communication control unit 8 can connect the communication request for the host A in communication to the dedicated line, and give priority to the communication request for the boss B to connect to the switched line. Leave it in this state.

Therefore, communication can be carried out exclusively with Bost A, and when the first communication with Bost B is completed, communication with Host B from another terminal device continues, and a communication request with Host B is sent to the destination management buffer 14. The connection will continue without switching as long as it is.

If a connection continues with the same destination using a priority connection on a switched line and a predetermined period of time elapses without switching to another host, a timer (not shown) indicates that the next host waiting for connection will be connected. can be switched to

When all communications with host B are completed, host C is next connected, and when another terminal device requests communication with host C, the terminal device is connected to enable communication in the same manner as described above.

In this way, the terminal device 1-1.1-2. - Communication requests from 4-n are preferentially communicated with host A with a high frequency of communication requests via a dedicated line, and communication requests are sent to host I-B, C, - which has a high frequency of communication requests, and However, if the host is the other party, communication can be given priority, so the frequency of switching connections to other hosts is significantly reduced, and line efficiency and system operational efficiency can be improved.

That is, the switching frequency is reduced, the line usage time is shortened, and the average connection waiting time is reduced, so that communications can be processed in a short time and the system can be operated efficiently.

Therefore, it is possible to improve the service.

In the above embodiment, an example has been described in which there is one dedicated line and one exchanged line, but the same effect can be obtained even if a plurality of any of them are used. In this case, for example, when there is a plurality of exchange lines, it is of course necessary to provide a plurality of destination pointers 92, line control units 15b, etc.

(g1) According to the present invention, as described in detail, the line usage time is shortened by reducing the frequency of switching destinations.

■Therefore, the system can be operated efficiently.

■ Service to customers can be improved.

There is an effect.
