BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging system for multimedia communication.

[0002]

2. Description of the Related Art Multimedia communication using multimedia terminals based on broadband communication technology is expected to be realized in the near future. In this multimedia communication, the information expression and the transmission ability, which were not sufficient in the conventional communication using only voice, become sufficient by adding the image information. In addition, in the communication information between the subscribers, information that the third party wants to provide (for example, advertisement regarding the third party).
It is also possible to generate value-added information by adding.

On the other hand, the communication charge is expected to be high because the amount of information transmitted is remarkably large, and the broadband communication service may not spread smoothly. Therefore, it is desired that the subscriber can easily use the broadband communication service by adopting a billing system (method) that can keep the communication fee paid by the subscriber low.

Conventionally, the charge for use of a communication medium (line) is uniquely based on the amount of information targeted for communication, communication time, communication time (daytime or midnight), terminal accommodation area, or the like. I have decided. Further, the fee for such communication is usually charged to the subscriber who has made the communication.

[0005]

When broadband communication is realized by a multimedia terminal, image information is transmitted in addition to conventional voice information, so that the amount of information to be communicated becomes very large. It is considered that the network usage fee will be high if the fee is charged in the unit of information, which has been performed in the past, for this enormous amount of method. In addition, since the broadband communication network operating company tries to recover expensive network equipment and operating costs, it is expected that the charges for using the network will be high.

[0006] For these reasons, it is expected that subscribers will be burdened with a heavy communication charge in multimedia broadband communication. In that case, it may be difficult to popularize broadband communication services.

The present invention has been made in view of the above circumstances, and its object is to provide a multimedia terminal.
Based on the idea to bear a portion of <br/> rates for communication subscriber to the advertisement information provider by placing also the advertisement information provider advertising information to communication information to be transmitted to the broadband communication The purpose is to reduce the charge burden on the subscribers and to promote the widespread use of broadband communication services.

The individual information is sent to the charging control unit 101 and determines the charging parameter to be used. Then, the charging control unit 101 in the additional information charging system 60B sends information about the charging parameter to the call control processing unit 103 in the additional information charging system 60A.

In step S26 shown in FIG. 17, the call control processor 103 of the exchange P refers to the received information about the subscriber B to determine from which exchange the subscriber B wants to receive the additional information. Identify. The information used for the above-mentioned specific processing is registered in the individual information shown in FIG. In FIG. 4, subscriber B requests to receive additional information from a switching center that receives a call sent from a certain switching center. When the subscriber B on the called side requests the reception of the additional information stored in the exchange P in which the subscriber A is accommodated, the subscriber B executes step S24. When the subscriber B requests the reception of the additional information stored in the exchange Q, the subscriber B executes the process S27 of FIG.

Before executing the processing S27, the information storage device determining unit 105 shown in FIG. 3 accesses the database,
The information about the additional information provider registered about the subscriber B is acquired. Then, steps S27-S31 are performed similarly to steps S7-S11 shown in FIGS.

In step S31, when the subscriber B is using the voice terminal, the additional information charging system 6
The call control processing unit 103 of 0B establishes the path illustrated in FIG. 18 in step S31-1. In FIG. 18, A means a subscriber accommodated in the exchange P, and X means an additional information provider accommodated in the exchange P. Further, B means a subscriber accommodated in the exchange Q, and Y

Is output. In response to the response signal ANM, the signal processing device 11 sends the connection signal CONN (A) to the network 50.
It is sent to the call control unit 10 of A.

Then, in step S32, the subscribers A and B communicate with each other. During this communication, the subscriber B is supplied with additional information from the information storage device 1 registered by the subscriber B.

When the subscriber B terminates the communication in step S33, the call control processor 103 sends the disconnect signal DISC,
It is transmitted to the signal processing device 11 of the network 50B via the subscriber communication control device 12. In response to the disconnection signal DISC, the signal processing device 11 of the network 50B sends the disconnection signal DISC (B) back to the call control processing unit 103 of the additional information charging system 60B. In step S34, the call control processor 103 of the system 60B releases the release completion signal R
EL-COMP (A) is sent to the signal processing device 11 of the network 50B. Then, the signal processing device 11 of the network 50B outputs the release signal to the signal processing device 11 of the network 50A. In step S35, the signal processing device 11 of the network 50A instructs the call control unit 10 to release resources and paths.

Further, in step S35, the call control unit 10 of the additional information billing system 60B releases the resource and the path. Usually, the calling subscriber A is charged, but the charge calculated in step S36 is applied to the subscriber B or the subscribers A and B.
Both may be charged.

According to the second embodiment of the present invention, a plurality of additional information charging call control systems are distributed in the multimedia communication system. Therefore, the load is not concentrated on a certain node in the multimedia communication system. Further, it is possible to effectively provide additional information unique to the region. If the two parties are far apart, the receiving subscriber may not be interested in the additional information from the information provider housed in the network connected to the remote originating network. Absent. In this case, the receiving terminal will be more interested in the additional information from the additional information provider accommodated in the network to which it is connected.

Next, a third embodiment of the present invention will be described.

In the first and second embodiments described above, the information regarding the additional information provider is registered in the database. According to the third embodiment, such additional information provider information can be displayed on the screen of each multimedia terminal. The information displayed includes the additional information provider, the content of the additional information, the discount rate, and the like. The subscriber can specify the additional information he wishes to receive by keyboard or other means.
The billing system receives and analyzes the information selected by the subscriber.

Furthermore, the display of the additional information can be controlled by the subscriber. For example, the subscriber can stop and restart the display of additional information. Further, it is possible to specify the display size of additional information to be superimposed on the entire screen. For example, items indicating various display sizes are displayed on the screen, and the subscriber selects a desired screen size.

The display size can be used as a billing parameter. The additional information provider is charged based on the screen size selected by the subscriber.

FIG. 22 is a discount table that defines the discount rate based on the display size. According to the discount table shown in FIG. 22, when the additional information is displayed on the entire screen,
The discount rate is 100%, and when it is displayed on the half of the screen, the discount rate is 50%. Even if the discount rate is 100%
But the bill is not zero. The discount rate based on the display size is as follows.

(Discounted fee) × (100−R) / 100 where R is a discount rate depending on the display size. Further, the discounted charge is the cost after discounted at the discount rate defined in the discount table shown in FIG.

A display size-based discount table for each additional information subscriber may be used.

Billing processing using the following first, second, and third display size-based discount tables is possible. The first billing process uses a timer prepared for each display size. These timers measure how long additional information has been displayed for each display size. The second billing process uses a single timer only for the smallest display size. Charging is based on the time measured by this timer. The third billing process uses a single timer for maximum display size only. Charging is based on the time measured by this timer.

FIG. 23 is a block diagram of a multimedia terminal. The multimedia terminal shown is a CPU 71,
ROM 72, RAM 73, communication controller 74 including a modem, keyboard 75, display unit 76,
