Description

  The present invention relates to a communication method and system, and more particularly to a communication method and system capable of delivering or exchanging presence status (current status) and text information in real time via a network such as the Internet.

  2. Description of the Related Art Conventionally, systems that can deliver or exchange presence status and text information in real time via the Internet are widely known as IM (Instant Message: a system that transmits characters, not voice). As shown in FIG. 15, this system is provided by a system including a plurality of communication terminals 1, a control device 2 that controls the whole, and the Internet 3 that connects them. Here, as the communication terminal 1, for example, a personal computer (personal computer: PC) in which a dedicated program is incorporated is used. In the figure, a case where user A to user E exist as users of communication terminal 1 is shown. Here, the communication terminal 1 and the user are indicated by the same number. That is, the communication terminal 1 and the user 1 are the same.

  In this IM system, the control device 2 monitors and records the presence status of the user of each communication terminal 1, and notifies the online communication terminal 1 of the online user of the presence status of other users' communication terminals. In addition, when the service user confirms the presence status of another user who wants to communicate and then delivers or exchanges text information to the user, the text information is automatically displayed on the communication terminal 1 of the user. As a result, real-time delivery is possible.

  When the user returns the delivered text information to the user, the returned text information is automatically displayed on the communication terminal 1 of the user, and the information can be exchanged in real time. An important feature of this service is that it can be delivered after confirming that the other party to whom information is to be sent can be confirmed immediately, and can communicate quickly and reliably.

  In contrast, e-mail is only delivered unilaterally to a computer that temporarily stores e-mails called mail servers used by the other party, so that the other party takes out the e-mail from the mail server in real time, There is no guarantee of confirmation, and you never know when it will be transmitted to the other party. From the point of view of real-time information, the telephone can be mentioned, but since the service uses the Internet, it is possible to communicate with users all over the world without incurring high communication costs.

  FIG. 16 is a sequence diagram showing a conventional IM service. The same components as those in FIG. 15 are denoted by the same reference numerals. In the figure, users A to D exist as users of the communication terminal 1, and these users and the control device 2 are connected to perform communication. Each of the users B to D registers the monitoring of the user A in the control device 2. The control device 2 monitors a change in the presence state of the user A. When the presence state of the user A changes, the control device 2 notifies each of the users B to D of the change in the presence state of the user A. Here, the presence state of the user A may have changed, for example, when the user A leaves the seat.

In this conventional communication method, as the number of monitoring terminals increases, the bursty signal amount increases and the burden on the control device 2 increases.
As a conventional device of this type, a technique is known in which the state inquiry interval of each conversation person is determined based on the observation value of the communication situation with the conversation person registered in the user terminal. (For example, refer to Patent Document 1).
