[0013]

The ISDN has a procedure for exchanging user / user information defined by the I-series Recommendations of the International Telegraph and Telephone Consultative Committee (CCITT) applicable to direct communication between communication terminals, and has a special communication control. There is no need to use a procedure, and a very low communication fee is charged when transmitting user-user information.

Focusing on this point, without using the call control message carrying the user / user information to form an information channel for exchanging information between communication terminals,
The interactive message communication is realized in a series of control procedures relating to a call connection on a signal channel for exchanging call control information between a communication terminal and an exchange or between communication terminals.

According to the above method, when a caller makes a call, the caller sends a call setup message in which a message to be delivered using a signaling channel (for example, a message inquiring a visit time) is included in user / user information. .

When the called party receives the call setup message via the signaling channel, the called party extracts user-user information carrying the caller's message from the call setup message. Then, a call message indicating that it is in an incoming call state (at this time, the signal channel for transmitting the call control signal is connected, but the information channel for exchanging information is not yet connected) is directed to the caller. Send out. At this time, in the call message, a message indicating that the message from the caller has been received, a response message to the caller, for example, a reply message to the inquiry about the visit time, and the signaling channel should be disconnected without connecting the information channel. The message of the called party who prompts the user to put it as user information.

When the caller receives this, the caller sends a disconnection message without waiting for the next reply message from the callee according to the normal call control procedure. At this time, the disconnection message can carry, as user / user information, a receipt report for the message from the callee and a response message to the callee, for example, a message indicating reservation or appointment of visiting time. The called party receiving this extracts the user-user information on the disconnect message and then releases the signaling channel.

Further, a message of the called party indicating a disconnection request as user / user information to be carried on the calling message,
Select a callee message that does not indicate a disconnect request to prompt disconnection without connecting the information channel, and then send a response message to switch to the normal call control procedure for connecting the information channel. It is also possible to select when and.

As described above, by putting the disconnection request message on the user / user information of the call message, the call setup message, the call message, and the disconnect message are used between the caller and the callee in the call control procedure. You can communicate with each other.

The receiving terminal T2 is also constructed as shown in FIG. 2 similarly to the transmitting terminal T1, and the RAMs 4 and 5 are used as follows. A call message, a response message, and a release message are stored in the RAM 4. R
The AM5 stores the message of the callee to be carried as the user / user information in the calling message and the message from the caller who has arrived as the user / user information in the call setup message and the disconnection message.

The ISDN network is a D channel (a signal channel for transmitting call control information, which is a signal channel for transmitting and receiving call control signals such as a call setup message, a call message, a response message, and a disconnection message at the time of making and receiving a call. , For example, 16 kb / s), and two information channels for transmitting information between terminals, B1 channel and B2 channel (information channel for transmitting call information, for example, transmission rate of 64 kb / s), are provided to communication terminals. To do.

The call setup message, the call message, the response message, and the disconnection message include one of the information elements, which is the user / user information that the user can use for exchanging information between the communication terminals.

The network interface unit 10 is an ISDN.
D, which is the signaling channel provided by the network

The CPU 1 sends and receives a call control signal to and from the network interface unit 10 via the system bus 2 based on the program stored in the ROM 3, and controls the entire operation of the calling terminal and the called terminal.

The network interface section 10 is a receiving means,
It functions as a first receiving means and a second receiving means.
Further, the CPU 1 functions as an extracting means, a sending means, a first sending means and a second sending means.

Next, the operations of the transmitting terminal T1 and the receiving terminal T2 using the message communication processing method capable of realizing the interactive message communication according to the present invention will be described. 3 is a flowchart showing a connection control procedure between the originating terminal T1, the exchange T3 and the receiving terminal T2, FIG. 4 is a flowchart showing a control procedure of the originating terminal T1, and FIG. 5 is a flowchart showing a control procedure of the receiving terminal T2. .

First, the connection control procedure among the calling terminal T1, the exchange T3 and the receiving terminal T2 in FIG. 3 is as follows. That is,

(1) The calling terminal T1 sends a call setting message in which the caller's message is added to the user / user information at the time of calling. (2) The receiving terminal T2 receives this call setup message at the time of an incoming call, and requests that the signal confirmation channel for the caller's message and the message from the callee be disconnected from the signaling channel without connecting the information channel. Returns a paging message with the message on the user-user information.

(3) When the calling terminal T1 receives this calling message and grasps the disconnection request from the called terminal T2, the receipt confirmation message for the message of the called party and the second message from the calling party are used as user / user information. Send the disconnection message. (4) The receiving terminal T2 receives this disconnection message and sends a release message. (5) The calling terminal T1 receives the release message and returns a release completion message. (6) The receiving terminal T2 receives this release completion message and ends the series of connection control procedures.

As described above, by adding a message requesting disconnection to the calling message, the normal ISDN
Of the connection control procedures of the above, which are inserted between (2) and (3) of the above-mentioned connection control procedures, and which are shown by hatching in FIG.
That is, the called terminal T2 sends a response message based on the off-hook operation of the called party, and the called terminal T1 and the called terminal T2
The procedure for forming a communication path between and is omitted so that it can be used.

The processing method used for each communication terminal in performing this omitting process is as follows. That is, ISDN
In the call control procedure, the receiving terminal T2 receives the call setup message from the calling terminal T1 as shown in FIG.
After sending the paging message, the user either responds to the communication state using the information channel or waits for a disconnection message from the calling terminal T1 and cannot disconnect himself.

Therefore, the receiving terminal T2 is the calling terminal T1.
In order to immediately shift to the disconnected state after receiving the call setting message from the device, it is indispensable to put a message requesting disconnection on the calling message and prompt the calling terminal T1 to shift to the disconnected state.

In consideration of the above, in order to enable the transition to the disconnection state immediately after sending the paging message, in (2) the receiving terminal T2 puts a message requesting disconnection on the paging message, and (3) ), It is possible to shift to the disconnection state by sending a disconnection message from the transmitting terminal T1.

In the above-mentioned embodiment, the procedure shaded in FIG. 3 inserted between (2) and (3) of the above-mentioned connection control procedure of the normal ISDN connection control procedure is omitted. However, in the communication processing method according to the present invention, the above connection control procedure is omitted by not including the message requesting disconnection in the call message at the receiving terminal T2 in (2). You can also choose to not.

Next, the operation of the transmitting terminal T1 will be described. At the time of calling, in step S101 of FIG. 4, the CPU 1 reads the caller's message sent along with the call setting message stored in the RAM 5, and then the RAM
The user / user information of the call setup message stored in 4 is read. Then, the caller's message that has just been read is added to the user / user information of the call setup message, and the ISDN is sent to the callee via the network interface unit 10.
Send to D channel of network.

Then, in step S102, a paging message is received via the D channel of the ISDN network as a return to the call setup message.
After performing this processing, in step S103, it is confirmed whether or not the message of the called party is included in the calling message as user / user information. If the message is included, the message requests disconnection in step S104. Check whether or not.

If the message is a message requesting disconnection between the caller and the callee using a predetermined format, in step S105, the callee who has arrived by riding on the user / user information of the calling message is reached. Stores the message from the user in the area for storing the user / user information of the RAM 5.

Next, in step S106, the CPU 1 sends a disconnection message to the receiving terminal T2 via the network interface unit 10. The disconnection message can carry a message of the sender and a message notifying that the message from the receiver has been received as user / user information. The receipt confirmation message uses a predetermined format between the sender and the recipient.

Next, in step S107, the release message sent as a return to the disconnect message is received, and in step S108 a release completion message is sent out, completing a series of connection control procedures.

In step S103, if the message of the callee is not included in the calling message as user / user information, step S104 is skipped. If the message does not request disconnection in step S104, step S10
At 9, the response message continuously sent from the receiving terminal T2 is received, and the state shifts to the communication start state of step S110. Then, after the communication end state in step S111, the process proceeds to step S106 and subsequent steps.

Next, the operation of the receiving terminal T2 will be described. The network interface unit 10 sends the ISDN the call setup message delivered as an incoming call from the calling terminal T1.
It receives it via the D channel of the network and sends this call setup message to the CPU 1. Upon receiving this call setup message, the CPU 1 confirms the presence / absence of user / user information in step S201 of FIG.

If there is user / user information, the user / user information is stored in the RAM in step S202.
The user / user information on the call setup message received at the time of the incoming call of No. 5 is stored in the area for storing. Then C
In step S203, the PU 1 determines whether or not to carry a message requesting disconnection without setting an information channel in the paging message to be transmitted next as user-user information.

When performing interactive message communication, the disconnection request is selected. When a message requesting disconnection is put on the RAM 4 in step S204, a message indicating that the message from the caller has been received and a message prompting the caller to disconnect the line are displayed as the message of the callee itself.
It is added to the user / user information of the call message stored in. Note that the receipt confirmation message and the disconnection request message use a predetermined format between the sender and the receiver.

Next, in step S205, the disconnection message sent by the calling terminal T1 which received the calling message sent by the called terminal T2 is received. Then, in step S206, it is confirmed whether or not the caller's message is included in the disconnection message as user / user information, and when the disconnection message is included, the user / user in the disconnection message received when the call arrives in the RAM 5 in step S207. Store in the area for storing information.

Next, in step S206, if the caller's message is not included in the disconnection message as user / user information, step S207 is skipped. Then, in step S208, R
The release message stored in AM4 is sent. In step S209, the release completion message transmitted by the transmission terminal T1 which has received the transmitted release message is received,
Complete a series of connection control procedures.

When there is no user / user information in step S201, and in step S203.
If the message requesting disconnection is not carried in step S210, a call message carrying no user / user information is sent out in step S210, and then step S2.
In step S21, a response message is transmitted.
2 shifts to the communication start state. Then, step S21
After the communication end state of 3, the other party waits for the disconnection in step S214, and the process proceeds to the reception of the disconnection message of step S205.

As described above, by using the message communication processing method according to the present embodiment, various interactive message communication other than the above embodiment, such as inquiry about product inventory, reply, application information, and medical treatment time, can be performed. Inquiries of
It is possible to realize communication for alternately sending and receiving reply / reservation information, content inquiry, reply, reply confirmation information, etc. within the ISDN call control procedure without preparing a special communication control procedure. Moreover, by utilizing the user / user information of the call message, message communication can be performed without setting the information channel.

Further, since the receipt message for the message from the sender and the message indicating the signal channel disconnection request can be carried in the paging message, the call control procedure on the signal channel can be performed without connecting the information channel. You will be able to communicate messages within.

[0053]

According to the present invention, by placing the disconnection request message on the user / user information of the call message, the caller and the caller can be received by using the call setup message, the call message and the disconnect message in the call control procedure. Since messages can be communicated with other persons, message communication can be performed between communication terminals, and the communication fee for the message communication is much higher than that when the communication path is connected. It can be cheap.
