Description

[Detailed Description of the Invention] [Table of Contents] Overview Field of Industrial Application ゛Prior Art (Fig. 5) Means for solving the problem to be solved by the invention (Fig. 1) Effect (Fig. 1) Figure) Embodiment (Figures 2 to 4) Effects of the invention [Summary] In a communication network system, communication information that allows a part of communication information from a terminal to be treated not only as communication information but also as signal information. Regarding the combined use of signal information, by adding some innovation to the interface circuit in the communication network system, the character dial receiver (CDR) that was previously required can be eliminated, and the connection path can be set in one time. A detour is provided on the transmission path for transmitting communication information from a terminal connected to the interface circuit, and a buffer is provided on the detour,
A portion of the communication information from the terminal is passed through a detour and temporarily stored in a buffer, and the information stored in the buffer is output as signal information to the network control unit, so that the information is used as control data. , the information in the buffer is configured to be transmitted as communication information by returning it to the transmission path again.

[Industrial Application Field] The present invention relates to a method of combining communication information with signal information, which makes it possible to treat a part of communication information from a terminal not only as communication information but also as signal information in a communication network system. .

With the shift to 15DN communication networks, in addition to conventional telephone services, services provided include TSS services that connect host computers and their terminals to the network, and mail systems that connect and link with telephones and personal computers. There is an increasing demand for e-mail services or information provision services connected to databases.

When a terminal of a host computer or a personal computer (hereinafter referred to collectively as a "terminal") is connected to a communication network that has a switching system and an attempt is made to provide the above-mentioned services, the switching system It is necessary to select and connect to a host computer, mail system, database, etc. as a connection destination according to the call information from the terminal. That is, the information first sent from the terminal must be used as a signal for the main controller (processor) of the exchange to determine the connection destination. However, all information from such terminals is also communication information that must be sent to the connected host computer or mail system. Therefore, there is a need for a system in which one communication information and signal information can be used not only as a signal by the main controller of the exchange, but also as communication information to be sent to the other party.

[Prior Art] FIG. 5 shows a conventional technique corresponding to such a method of combining communication information with signal information.

In the system shown in FIG. 5, a terminal accommodating circuit 102' that separates information from a terminal 101 into a signal component and a communication information component is connected to the front end of the exchange 100, and a terminal accommodation circuit 102' is connected to the back end of the exchange 100. A terminal accommodation device 103 that can combine signal components and communication information components, and a character dial receiver that receives characters from the terminal 101.
eiver:CD R) 104 is connected.

Note that 105 is a main control device that controls the connection path of the exchange 100, and 106 is a terminal such as a host computer or a mail system.

With the above configuration, information from the terminal 101 is first separated into a signal component and a communication information component by the terminal accommodation circuit 102'. Of these, the signal component is transmitted to the main controller 105.
This signal causes the connection path of the exchange 100 to be
First, the terminal 101 and the CDR 104 are connected (see ◯ in FIG. 5), information from the terminal 101 is transmitted to the CDR 104, and the information is stored in the CDR 104.

Next, the main controller 105 reads out the information stored in the CDR 104 and determines the original connection destination of the CDR 104 .

After that, the connection path of the exchange 100 is extended from the CDR 104 to the connection destination (see ■ in Figure 5), and after the information from the CDR 104 is sent to the connection destination, the connection path is extended from the terminal 101 to the connection destination.
Replace the cable between the connection destinations (see ■ in Figure 5) and complete the final connection path setting.

In this way, communication between the terminal 101 and the terminal 106 such as the host computer is started for the first time.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, the exchange 100
It is necessary to change the connection path three times: first between the terminal 101 and the CDR 104, then between the CDR 104 and the destination, and then between the terminal 101 and the destination. Yes, this allows exchange 100
There is a problem in that the control becomes complicated and the processing cost associated with connection path setting of the main control device 105 is tripled.

Also, by attempting to connect a host computer terminal or personal computer to a regular telephone,
In addition, it is necessary to connect CDR104 at the same time,
This also poses a problem of complicating the system and increasing costs.

The present invention was made in view of these problems, and
By adding some ingenuity to the interface circuit in the communication network system.

It is an object of the present invention to provide a method for using communication information in combination with signal information, which eliminates the need for CDR, which was conventionally required, and allows connection paths to be set in one time.

[Means to solve the problem] FIG. 1 is a block diagram of the principle of the present invention.

The schematic configuration of the device according to the present invention shown in FIG. 1 is equivalent to the conventional example shown in FIG. 5 with the CDR 104 removed, and is completely similar to a general network configuration diagram. That is, the terminal accommodation circuits 102 and 10 are installed in the exchange 100.
3 is connected to a main control device (network control section such as a call processing section) 105, and terminal accommodation circuits 102 and 103 are connected to terminals 101 and 106.

By the way, the configuration inside the terminal accommodation circuit 102 is different from the conventional one. That is, a detour (detour path) 1 is provided on the transmission route (information transfer path) within the terminal accommodation circuit 102, and a temporary storage buffer 2 is provided on the detour path 1 to temporarily store information. is provided.

And regarding the information in this buffer 2.

The main control device 105 can read data via the control circuit 3 in the terminal accommodation circuit 102.

A changeover switch 4 is provided at the branch point between the information transfer path and the detour path 1. Route switching by this switch 4 is performed by the control circuit 3 by exchanging signals (protocol) between the terminal 101 and the main control device 105. It looks like this.

Note that 5 is a merging unit that merges each piece of information on the information transfer path and the detour path 1, and 6 is an information-signal separator that separates information from the terminal 101 into signal components and communication information.

[Operation] With the above-described configuration, signal information is first exchanged between the terminal 101 and the main control device 105 immediately before the information is transferred from the terminal 101. As a result, the main controller 105 instructs the control circuit 3 of the terminal accommodating circuit 102 to switch the changeover switch 4 to the bypass path 1 side, and
Information from 1 will pass through detour path 1. Therefore, destination information, etc. first passes through the detour path 1 side, and then passes through the buffer 2.
is temporarily accumulated.

When the destination information etc. are accumulated in the buffer 2 in this way, the control circuit 3 transfers the information to the buffer 2 according to instructions from the main controller 105.
The information is read out and passed to the main controller 105.

The main controller 105 uses this information as data for control (call processing) to determine the connection destination of the terminal 101 and establishes a connection path within the exchange 100.

After that, follow the instructions from the control circuit 3 to select the changeover switch 4.
is switched to the information transfer path side, and the accumulated information in the buffer 2 is sent to the exchange 100 via the merging unit 5.

It is equipped with i.

FIG. 4 is a block diagram showing the detailed configuration of a terminal accommodating circuit (line circuit), and shows one for a terminal of a host computer or a personal computer.

First, this terminal accommodation circuit 110-ij is divided into two parts, a transmitting section 1o and a receiving section 20. The transmitting section 10 has a configuration example including an information transfer path and a detour path, and the receiving section 20 has a general configuration. It is similar to that of .

The transmitting unit 10 includes a transmitting channel counter 11, a transmitting channel number storage register 12 . Comparator 13. Information-signal separator 14. Selector switch 15, transmission buffer 1
6. - Time accumulation buffer 17° merge section 18. Control circuit 1
9, the receiving section 20 includes receiving channel counters 21 . Receiving channel number storage register 22. Comparator 23° information-signal fuser 24. It is configured with a reception buffer 25.

Here, the transmission channel counter 11 counts the channel number to be multiplexed on the current uplink switching bus USBi, and is incremented by the channel clock from this uplink switching bus USBi.

The transmission channel number storage register 12 is the terminal 108-i.
j is a register storing the channel number in which the information should be placed, and is set by the controller 112i when the path is connected.

The comparator 13 compares the values of the transmission channel counter 11 and the transmission channel number storage register 12, and if they are equal, outputs a signal to the transmission buffer 16, instructing it to send the information in the transmission buffer 16 to the uplink switching bus USBi. It is something.

Information-signal separator 14 is a device that separates time-division multiplexed information and signals from terminals 108-ij.

The changeover switch 15 is a device that switches the path of information under the control of the control circuit 19.

The transmission buffer 16 is a buffer for multiplexing transmission information in synchronization with the transmission channel.

The - time storage buffer 17 is a buffer for temporarily storing transmission information placed on the detour path 1, and is readable by the control circuit 19.
The stored information is transferred to the upstream switching bus US
It is designed to be sent on Bi.

The merging unit 18 is a confluence point of paths, and the control circuit 19 transmits and receives signals to and from the terminal 108-ij, exchanges signals with the control device 1121, switches paths using the changeover switch 15, or transfers information in the temporary storage buffer 17. It controls transmission.

Furthermore, the reception channel counter 21 counts the channel number demultiplexed on the current downlink switching bus DSBi, and
The count is increased by the channel clock input from Bi.

The reception channel number storage register 22 is a register that stores the channel number to be received, and is set by the control device 1121 when a path is connected.

The comparator 23 compares the values of the reception channel counter 21 and the reception channel number storage register 22, and if they are equal, outputs a signal to the reception buffer 25 and outputs a signal to the downlink switching bus D.
This is an instruction to receive information on SBi.

The information-signal combiner 24 is a device that multiplexes received information and signals, and the reception buffer 25 is a buffer that stores received information.

With this configuration, first, when transmitting information, the control circuit 19 switches the changeover switch 15 to the detour path 1 by exchanging signals between the terminal, the control circuit 19, and the control device 1121. As a result, information from the terminal is temporarily stored in the temporary storage buffer 17.

When the information from the terminal is temporarily stored in the temporary storage buffer 17 in this way, the control device 112j instructs the control circuit 19 to read out the information in the -time storage buffer 17, thereby determining the connection destination.

When the connection path is set in the switching module 100' in this way, the values of the channel number registers 12.22 for transmission and reception are set accordingly, and the information in the temporary storage buffer 17 is first transferred to the upstream switching bus USB i. After that, the changeover switch 15 is switched to the regular information transfer path, and the subsequent information is sent to the transmission buffer 16.
via the upstream switching path USBi.

On the other hand, the receiving unit 20 receives only the channel information of the value of the receiving channel number storage register 22, as in a general receiving operation.

An example of a service using this method is as follows. In other words, if you connect a host computer, mail system, or database as a connection destination, log on from the terminal or personal computer.
Typing TSS connects to the host computer, MAIIJAN connects the mail system, and ENOTIES connects the database.

In this way, if one hydraulic type is used, there is no need to switch the connection paths within the exchange three times as in the conventional technology, and the
There is no need to connect a device such as a DH to the exchange, and the connection path can be set in one go by simply providing a detour path and an information storage buffer in the configuration of the terminal accommodation circuit. Control associated with connection path setting is simplified, and processing costs associated with connection path setting can also be reduced.

[Effects of the Invention] As detailed above, according to the method of combining communication information with signal information of the present invention, it is only necessary to provide a detour path and a buffer in addition to the information transfer path in the interface circuit in one communication network system. Since the connection path settings within the exchange can be completed once and there is no need to install a CDR, the control associated with connection path settings within the exchange is simplified, and the processing costs associated with connection path settings are also reduced. There is an advantage that can be reduced.
