[Industrial applications]
The present invention relates to a communication method for performing so-called automatic communication in communication mainly performing character transmission via a communication network, such as personal computer communication, and a communication control device therefor.
[0002]
[Prior art]
Automatic communication used in personal computer communication, etc. is what is called autopilot, and transmits a specified character string to a specified received character string in a specified order, or connects / disconnects a line. This is a communication method that performs FIG. 16 shows a conventional sequence of this automatic communication. FIG. 16 shows a case where automatic communication is performed between a host terminal and a user terminal via a communication network.
[0003]
The automatic communication sequence will be described below with reference to FIG.
(1) Connect the line from the terminal by manual or automatic communication procedure.
(2) The user terminal transmits the response character string 1 to the character string 1 received from the host terminal according to the automatic communication procedure.
{Circle around (3)} In response to the response character string 1 from the user terminal, the host terminal transmits the next character string 2 as a response.
(4) Automatic communication is executed by repeating the above (2) and (3).
(5) When the automatic communication is completed, the line is disconnected by a manual or automatic communication procedure.
[0004]
Here, the automatic communication software is built in the user terminal, and the automatic communication procedure is also stored in the user terminal in advance.
[0005]
In this automatic communication, automatic communication is performed in the form of repetition of a response to a received character string. Therefore, even if, for example, a full-duplex line is used, transmission data and reception data are rarely exchanged at the same time. The exchange of character string transmission → response → character string transmission → response is repeated. In this exchange, when it takes time to respond to the received character string between the host terminal and the user terminal, the communication line remains occupied for the time even though there is no transmission / reception data.

However, the line is disconnected and reconnected one by one during a relatively short blank time such as between the received character string of the host or the terminal and the response. In this case, the number of disconnections and reconnections increases remarkably, the efficiency is low in consideration of the time required for reconnection of the line, and the amount of call processing on the network side remarkably increases, placing a heavy burden on the network. .

In the figure, among the signals on the DTE side, DR (data set ready), ER (data terminal ready), CS (modem transmission possible), RS (transmission request), etc. Are omitted. These are not necessary.
[0058]
Data direction control on the network side, terminal side, and control unit side is performed by buffer gates 31 to 34. The direction control of these buffer gates 31 to 34 is controlled by the CPU 13 through the parallel input / output device 12 depending on whether the buffer gates 31 to 34 are used on the host side or the user side, and according to the situation at that time.

[0063]
In this embodiment, before the communication, the automatic communication procedure of the user terminal is loaded from the user terminal to the user side CCU in the form of a script. After exiting to the 25bis command mode, the automatic communication script may be transferred by the SCR command in the same manner as in the figure.
[0064]
Hereinafter, the procedure of the local automatic communication by the apparatus according to the embodiment will be described with reference to the sequences of FIGS.
[0065]
Before starting communication, the user terminal transmits a script indicating an automatic communication procedure to the user side CCU according to a script mode transition instruction “SCR” in advance. When the transmission command "CRN123" from the user terminal is received by the user-side CCU, the user-side CCU instructs the user-side modem to connect to the line (LOOP ON, SELECT123). The user-side modem issues a call (hook-on, selection signal transmission) to the host side.
[0066]
When there is an incoming call, the host-side modem notifies the host-side CCU of the incoming call “INC”. On the other hand, the host-side CCU instructs "LOOP ON" to the host-side modem, the host-side modem performs carrier transmission / detection, and transmits a CD signal on to the host-side CCU.
[0067]
On the user side as well, the user modem transmits / detects the carrier and transmits the CD signal on to the user CCU. The user CCU transmits the CD signal on and the DR signal on to the user terminal, and then transmits the split transfer to the user terminal. Send "SCRPT SND" for display. It should be noted that “SCRIPT SND (SENDING)” indicating script transfer to the user terminal may not be necessary if there is no need to display it on the user terminal side.
[0068]
After the line connection, a script indicating the automatic communication procedure of the user terminal is transmitted from the user side CCU to the host side CCU, and the received automatic communication procedure is stored in the automatic communication procedure storage unit provided in the RAM 14 at the host side CCU. I will do it. When all the automatic communication procedures have been transmitted, the user side CCU sends a LOOP OFF to the user side modem, and the user side modem disconnects the line (hook off).

When the host-side CCU receives the line disconnection notification “CD signal off” from the host-side modem, after the line disconnection, it notifies the host terminal of an incoming call notification (INC), a carrier detection notification (CD signal on), and a line connection notification (CD signal on). DR signal on), and then executes local automatic communication with the host terminal according to the received automatic communication procedure of the user terminal (character string 1, response 1, character string 2, response 2,..., Character Column x, end response). This execution result is stored in the automatic communication execution result storage unit provided in the RAM. When a termination response is sent from the host-side CCU to the host terminal, the host-side CCU notifies the host terminal of "CD OFF" and performs a line disconnection notification (DR signal off).
[0070]
In this way, when the local automatic communication between the host-side CCU and the host terminal ends, the host-side CCU reconnects the line to the disconnected user side. The user is notified of this line connection to the user terminal, but the host has already notified the host terminal at the end of local automatic communication that the line has been disconnected, and will not be notified again.
[0071]
After the line is connected, the host-side CCU transmits all the execution results of the local automatic communication stored and stored to the user side in a lump. When receiving the execution result, the user side CCU transfers the execution result to the user terminal as it is.
[0072]
After transmitting all the execution results, the host-side CCU instructs the host-side modem to "LOOP OFF" and disconnects the line. When the user side CCU detects that the line has been disconnected on the user side, it notifies the user terminal of the line disconnection (DR signal off or CD signal off).
[0073]
In the above-described embodiment of the local automatic communication method, the time for transmitting the automatic communication procedure from the user to the host needs to be set separately from the transmission and reception time of the actual automatic communication data (character string and its response). That time is wasted. A local automatic communication method as another embodiment capable of solving this problem will be described below with reference to FIGS. In the sequence of the embodiment shown in FIGS. 11 and 12, automatic communication is started at the time of automatic communication, and the automatic communication procedure is transmitted to the partner CCU side via the full-duplex line during the automatic communication. Thereafter, the line is disconnected and the remaining automatic communication is performed by local automatic communication.
[0074]
The meaning of each symbol in the figure is the same as described above. It supports 25bis command. As described above, the automatic communication procedure is loaded into the control unit of the user side CCU from the user terminal in the form of a script before communication. After exiting to the 25bis command mode, the automatic communication script may be transferred by the SCR command in the same manner as in the figure.
[0075]
Hereinafter, the procedure of another embodiment of the local automatic communication by the apparatus of the embodiment of FIG. 6 will be described in accordance with the sequences of FIGS. 11 and 12.
[0076]
Before starting communication, the user terminal transmits a script indicating an automatic communication procedure to the user side CCU in advance by using a script mode transition command “SCR”. When the transmission command "CRN123" from the user side is received by the user side CCU, the user side CCU issues a line connection instruction (LOOP ON, SELECT123) to the user side modem. Thus, the user-side modem issues a call (hook-on, selection signal transmission) to the host side.
[0077]
When there is an incoming call, the host-side modem notifies the host-side CCU of the incoming call (INC), and the host-side CCU notifies the host terminal of the incoming call (INC). When the line is connected, the host-side CCU notifies the host terminal of the line connection (CD signal ON, DR signal ON).
[0078]
Also on the user side, the user side modem transmits and detects the carrier, and the user side CCU notifies the user terminal of the line connection (CD signal ON, DR signal ON).
[0079]
After the line is connected, normal automatic communication is executed. In this automatic communication, the user CCU transmits all the characters while the character string is transmitted from the host via the full-duplex line downlink. A script indicating the automatic communication procedure of the user terminal stored in the RAM is transmitted to the host side CCU via the uplink of the heavy line (character strings n, n + 2,... K, scripts 1, 2,... m). The host-side CCU stores the received automatic communication procedure in an automatic communication procedure storage unit provided in the RAM. When all the automatic communication procedures have been transmitted, the user number (DLE + i) is transmitted, and then the line cutoff instruction “LOOP OFF” is sent from the user side CCU to the user side modem, and the user side modem cuts off the line (hook on). ). At this time, an indication of RESEAVED is sent to the user terminal.
[0080]
After the line is disconnected, the host-side CCU executes the remaining automatic communication with the host terminal by local automatic communication based on the automatic communication procedure of the user terminal received from the user side (response k, character string k + 1, Response k + 1... Character string x, end response). This execution result is stored in the automatic communication execution result storage unit provided in the RAM.
[0081]
When the local automatic communication between the host-side CCU and the host terminal is completed, the host-side CCU notifies the host terminal of the line disconnection (CD signal off, DR signal off), and then connects the line to the user again. For this line connection, the line can be connected to the intended user by referring to the previously received user number (DLE + i). On the user side, the connection of the line is notified to the user terminal (incoming notification INC, reconnection notification RECONNECT).
[0082]
After the line is connected, the host-side CCU transmits all the execution results of the local automatic communication stored and stored to the user side in a lump. Upon receiving the execution result, the user side CCU transfers the execution result to the user terminal as it is.
[0083]
After transmitting all the execution results, the host-side CCU instructs the host-side modem to "LOOP OFF" and disconnects the line. When the user side CCU detects that the line has been disconnected on the user side, it notifies the user terminal of the line disconnection (DR signal off or CD signal off).
[0084]
In the above two embodiments of the local automatic communication sequence, the script indicating the automatic communication procedure is transmitted from the user side CCU to the host side CCU after the start of the communication, but this transmission is also performed by the script received by the host side CCU previously. By keeping the memory continual, there is no need to do this each time communication is performed, unless there is a change in the automatic communication procedure.
[0085]
Further, in the above two embodiments of the local automatic communication sequence, the call for transmitting the execution result of the local automatic communication to the user is made from the host CCU, but the call may be made from the user. Good. In such a case, after the end of the initial call indicating the activation of automatic communication, the user side makes a call connection to the host side at an arbitrary time when a time at which the local automatic communication is considered to have ended has elapsed on the host side. I do. A code indicating the connection for starting the automatic communication or the connection for reading the execution result may be transmitted from the user CCU to the host immediately after the connection. The host CCU stores the execution result of the local automatic communication until the execution result is read (transmitted).
[0086]
On the other hand, when calling from the host side as in the above two embodiments of local automatic communication, the telephone number of the user side is required, but in the case of ISDN or digital car / mobile phone, the caller is required. The CCU on the host side can automatically know this by the number notification. In the case of a general subscriber telephone network or the like, for example, a telephone number or the like indicating a return destination of an automatic communication result is described in a script. Alternatively, a telephone number corresponding to a code for identifying a user such as a user ID is stored in advance.
[0087]
When the local automatic communication is applied to a system in which the host can access a plurality of user terminals, it is necessary for the host to identify each user and store and manage an automatic communication procedure and an automatic communication execution result. Therefore, the host may monitor the communication and identify the session of each user by the user ID. Alternatively, at the start of communication, the user sends a session start code to the host, the host assigns a session number to the session correspondingly, notifies the user terminal, and exchanges the session number when communication is resumed after the line is disconnected. By doing so, the user may be identified, and the execution result of the local automatic communication may be transmitted.
[0088]
In the above two embodiments of the local automatic communication sequence, the execution result of the local automatic communication may be data-compressed and transferred collectively. For example, if the data compression ratio is four times, the line connection time will be a quarter of the time reduced by the present invention.
[0089]

In this embodiment, the present invention is applied to a communication control device for an analog car / mobile phone. However, the modem units 17, 18 and the audio amplifier units 19, 20 are removed to remove SIO (serial input / output). By inputting and outputting signals to and from the mobile phone, a communication control device for a digital mobile phone is obtained.
[0090]

[0091]
In the apparatus of the embodiment shown in FIG. 6, the data direction control is partially implemented by hardware using the gates 31 to 34. However, in the apparatus of the embodiment, as shown in FIG. Is directly connected to the serial input / output device 11, and the signal from the terminal (DTE) is also directly connected to another serial input / output device 15, thereby realizing all of them in software.

Similarly, the apparatus of the embodiment shown in FIG. 13 may be realized by a crossbar switch.
[0093]

[0094]
【The invention's effect】
As described above, according to the present invention, the time when automatic communication is simply performed between the user terminal and the host terminal is compared, and the result of executing the automatic communication between the host terminal and the host-side communication control device is batched. The time required for the method of transmitting data to the user terminal is shorter by the response time between the user terminal and the host terminal and the processing time on the host side. The use efficiency can be improved by eliminating unnecessary occupation, and the line usage fee is not charged for the time the line is disconnected, which greatly contributes to economic efficiency.
[0095]
In particular, when the present invention is applied to a wireless network such as an automobile or a mobile phone, the occupation time of the line is shortened, which greatly contributes to the effective use of the radio frequency.
Also, since the number of times of line disconnection / connection is increased only once due to execution of automatic communication, the call processing amount on the network side is larger than the method of repeating line disconnection / connection every certain blank time. The increase is small.
[0096]
According to the method of transmitting the automatic communication procedure to the communication control device on the host side during reception of data from the host side, no extra time is required for transmitting the automatic communication procedure, so that the line is further occupied. The time is short, which greatly contributes to economic efficiency.
[0097]
According to the method of executing and managing local automatic communication for each user by identifying a plurality of users, the host accepts accesses from a plurality of terminals at the same time, and performs the above-described processing for an access from a plurality of terminals. You can enjoy the advantages of the invention.
[0098]
The following is an example of the effect obtained based on the measured values when the personal computer communication is performed automatically using the analog extension telephone.
As an example,
Modem communication speed 2400bps
Total communication time 61.0 seconds
Total blank time 28.4 seconds
Terminal received data 6675 bytes
Therefore, the actual communication speed is
6675 / 61.0 = 109.4 bytes / second
And Table 1 below shows the blank time (time in the no-data state) at this time and its frequency.
[0099]

[0100]
FIG. 14 shows a graph of this. From FIG. 14 and Table 1, it can be seen that there is a large number of occurrences of a short blank time of 1 second or less, especially about 0.2 to 0.3 seconds.
[0101]
At this time, if the present invention is applied, the line occupation time for transmitting the automatic communication execution result is shortened by the blank time, so that the substantial communication speed when the present invention is applied is 6675 / (61. 0-28.4) = 204.8 bytes / sec. However, the time for transmitting the automatic communication procedure and the overhead for disconnecting / reconnecting the line are excluded.
[0102]
Theoretically, there is a possibility that the communication speed can be improved from the physical communication speed to 240 bytes / second (start bit 1, stop bit 1, start-stop synchronization).
[0103]
Therefore, as compared with the case of performing normal automatic communication, the actual communication speed is improved about twice, and the line use time and the communication cost associated therewith can be reduced to about 1/2.
[0104]
For reference, FIG. 15 shows a comparison of a communication cost with respect to a monthly communication amount when applied to a current analog car mobile phone. Usually, the communication volume per month is about 1 to 2 Mbytes. For comparison, the case where a teleterminal which is a packet switching network is used is also shown. However, VAN access fees are excluded. The basic amount of a car mobile phone is 16,000 yen / month, the usage fee is 10 yen / 7 seconds, the basic amount of a teleterminal is 2400 yen, the usage fee is 1.2 yen / 32 bytes (15% discount for 128 kbytes / month or more) ). From this, it can be seen that applying the present invention can reduce the communication cost to almost the theoretical limit.
