Abstract

PURPOSE:To enhance the transmission efficiency of information and to attain effective information communication while utilizing control of call setting by dividing user-user area of a call setting message into plural areas and sending plural kinds of information sets. CONSTITUTION:When a caller terminal equipment 1 makes a call, a call setting message in which each information is stored in the user-user area is sent to an exchange 2. Then an exchange 2 checks a called terminal equipment according to the call setting information in the call setting message to check whether or not there is an idle information channel. When an idle information channel exists, the call setting message is sent to the called terminal equipment and when no idle channel exists, the call is regarded as a call in busy state and the call setting message is sent to the called terminal equipment 3. The terminal equipment 3 receives the call setting message informed from the terminal equipment 1, extracts the information loaded in the user-user area A and displays, e.g. a caller name and a called party name. Then the reception of the call setting message by the terminal equipment 3 is informed to the exchange 2, which informs the information to the terminal equipment 1.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Field of Industrial Application) The present invention relates to an electronic exchange system accommodating a digital line having an information channel, and an information transmission system that enables effective transmission of information. Regarding.

(Prior Art) Recently, switching systems are being computerized, and lines are being digitized. In exchange systems that accommodate digital lines, call setup is controlled using the information channels of the digital lines. Specifically, the originating party I is sent to the above information channel.
D and called party ID to form a call setup message,
This call setting message is used to control the call setting.

According to such a call setting message, it becomes possible for the called party to know the calling party and the called party from the calling party ID and the called party ID. However, it is difficult for users to understand even if the code information of the calling party ID and called party ID is displayed as is, and it is difficult for the user to understand the code information of the calling party ID and called party ID, and it is difficult for the user to understand the code information of the calling party ID and called party ID. There is a problem that, for example, all of the information must be registered in advance in order to display it. Moreover, since the conversion and display of the above information is left to the processing of the called party,
For example, if there is a mistake in changing registration information or an omission in registration, there is a problem in that the information intended by the calling party is not necessarily displayed on the called party.

In addition, when data communication is performed between data terminals via the above-mentioned digital line, the call setup is controlled by notification of a call setup message via the information channel, and the call setup is used to control the communication for data communication. This is done by forming a channel.

However, after the communication channel is set up, the type of processing is determined, and it may take some time for the called party to be ready. Meanwhile, even if there is only a small amount of data to be transmitted, there are problems such as the communication channel being unnecessarily occupied.

(Problem to be Solved by the Invention) In the conventional switching system accommodated in a digital line as described above, the calling party ID and the called party ID are not notified to the called party in the call setup message of the information channel. However, there were also problems such as difficulty in accurately notifying the called party of the information.

The present invention has been made in consideration of these circumstances, and its purpose is to effectively transmit information on each yuzu by effectively utilizing call setting messages notified using an information channel. The objective is to provide an information transmission method that can

[Configuration of the Invention (Means for Solving the Problems) The information transmission method according to the present invention is a method for controlling call settings transmitted via an information channel in a switching system that accommodates digital lines. This was done by focusing on the user/user area in the message.The user/user area in the call setup message is divided into multiple areas using delimiter codes, and these divided user/user areas are This system is characterized by using areas to transmit multiple types of information at the time of call setup.

(Operation) According to the present invention, the user-user area in the call setup message transmitted via the information channel is divided into a plurality of areas by delimiter codes, and each of the divided areas of the number of stages is By loading the information, a plurality of pieces of information loaded in the user user area can be transmitted all at once when the call setup message is transferred.

Therefore, if information such as the calling party's name and the called party's name is placed in multiple areas separated by user/area delimiter codes, that information will be accurately notified to the called party during call setup. This eliminates the need for conventional caller ID conversion and display.

Furthermore, when transmitting only a small amount of data such as processing commands and processing parameters, the purpose of communication can be achieved by simply transmitting the call setting message using the user-user area.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the frame structure of a call setting message transmitted from a calling party to a called party via an ↑n information channel of a -J2 digital line in an exchange system accommodating a digital line.

This call setup message consists of a protocol number at the beginning, followed by an information area necessary for call setup processing such as a call number and a message, and a user area A of about 128 octets after that. be done. This user-user area A is freely open to unused users, but no special arrangements have been made regarding its usage.

The present invention divides this user-user conflict area A into a plurality of fields C using a predetermined delimiter code B as shown in FIG. The present invention is characterized in that the information is simultaneously transmitted during call setup processing by transmission. Specifically, according to the rules agreed upon in advance with the called party, a call setup message is transmitted with, for example, the information of the calling party's name in the first field and the information of the called party's name in the second field. It is characterized by the fact that

The called side that receives this call setting message extracts the information of each field delimited by the above delimiter code B in the user/user/factory of the call setting message, and communicates with the above-mentioned calling side. The computer is configured to display, display, output, etc. the information in accordance with predetermined rules.

Figure 2 is a diagram schematically showing the schematic configuration of a switching system realized by applying this method and the operation of this method therein, where 1 is a calling terminal, 2 is an exchange, and 3 is a called terminal. Each side terminal is shown.

Therefore, when the calling terminal 1 makes a call to the called terminal 3, according to the rules decided in advance between the terminals, for example, each of the users in the user area A divided by the delimiter code as described above is Field C contains information on the name of the calling party and the name of the called party, respectively. The information on the calling party's name and the called party's name is given, for example, as a character code string.

After setting and inputting the information of the calling party's name and the called party's name in this way, when a call is made from the calling terminal 1, a call setup message containing the above information in the user area is sent to the exchange 2. Transmitted (state ■). Then, the exchange 2 checks the called terminal according to the call setting↑11 information in the call setting message, and checks whether the information channel to the called terminal becomes vacant. If the information channel is free, the call setting message is sent to the called terminal 3 as is, and if the information channel is not free, the call setting message is sent to the called terminal 3 as a call in progress. (Status ■).

The called terminal 3 receives the call setup message notified from the calling terminal 1 in this way, extracts the information contained in the user area A, and sends the caller, for example, Displays the first name and the called name (state ■). After that, the called terminal 3 notifies the exchange 2 that it has received the call setup message (state ■), and the exchange 2
notifies the calling terminal 1 of the information (state ■).

Thereafter, upon completion of the notification of the call setting message, the exchange 2 sends a ring tone to the called terminal 3 and calls it, and also returns a ringback to the calling terminal 1 (state ■■). Upon receiving such a call, the user of the called terminal 3 confirms the displayed information as described above and performs an operation to answer or disconnect (state ■), and then the user of the called terminal 3 confirms the displayed information as described above and performs an operation to answer or disconnect (state ■). A response or disconnection instruction is returned to side terminal 1 (
Status ■ [phase]).

Thus, according to this information transmission system, the calling party's name and the called party's name can be displayed on the called terminal while the call is still in the calling state, simply by communicating the call setting message that controls the call setting. Therefore, the called terminal 3 can confirm the calling party's name and the called party's name during the call state.
This makes it possible to take appropriate responses. This also makes it possible to suppress wasteful communication and waste of call time.

In addition, even if the call is incoming during communication, the caller's name and 41
For example, the person specified by Takana Ishiyuki can wait for a line to be connected due to an available call line, or use another terminal to contact a specific person specified by the caller's name. It becomes possible to send a call back to the other party. Therefore, it is possible to take effective countermeasures while remaining in the calling state simply by communicating the call setting message.

Moreover, since this is different from conventional methods that display information by converting the calling party ID and called party ID, there are no problems caused by, for example, omissions in registration of conversion information or changes in registration, and reliable information transmission is possible. Effects such as being made possible can be achieved.

By the way, it is also possible to transmit a small amount of data by using the fields of the user/user area divided by the delimiter code as described above. For example, in data communication between data terminals, the calling terminal transmits command information that instructs the process to be performed, as well as several processing parameters necessary for the processing, from the calling terminal to the called terminal. Sometimes that's enough.

In such a case, for example, if the command information is placed in the first field and some processing parameters are placed in the second and subsequent fields and the call setup message is transmitted, the call status will remain due to the notification of the call setup message. It becomes possible to transmit information for communication purposes. And in this case,
Since the purpose of information communication is achieved only by receiving the call setup message, by giving a disconnection instruction from the called terminal, the call channel based on the call setup message is not set up in vain, and the communication path becomes effective. It becomes possible to plan the utilization. Further, it is possible to prevent unnecessary wastage of call time.

It should be noted that the present invention is not limited to the pointed embodiment described above. For example, it is possible to use a delimiter code as a prefix, or to attach an item number to the prefix. Further, the number of fields to be divided and formed by the delimiter code may be determined depending on the number of information items to be communicated and the number thereof. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, the user area of the call setup message is divided into a plurality of areas and a plurality of types of information are transmitted. Great practical effects can be achieved, such as making it possible to carry out effective information communication using call setting control.
