Abstract

PROBLEM TO BE SOLVED: To charge the tariff of ISDN user/network interface at a fixed rate to both sides by setting the threshold value of communication quantity on the respective sides of transmission and reception and automatically switching channels when the tariff uses two B channels in charge of the sides of transmission and reception and the communication quantity exceeds the threshold value. SOLUTION: Terminal equipment 1 sets the previously registered threshold value of data communication quantity or communication time to the user-to-use information of call setting message and requests the connection of B channel 6 to terminal equipment 10. The terminal equipment 10 stores the threshold value in a memory part 14 and monitors incoming calls and when they exceed that threshold value, switching to a B channel 7 is requested to the terminal equipment 1 by a B channel switching means 13 while adding its own threshold value registered in advance. The terminal equipment 1 stores that threshold value in a memory part 5, switches the channel to the B channel 7 and monitors that channel and when the communication quantity exceeds the threshold value, the channel is switched to the B channel 6. Afterwards, similar operation is repeated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a data communication system using a basic interface of a network interface, and particularly to a communication charge control system.

[0002]

2. Description of the Related Art Conventionally, this type of data communication system using a basic interface of an ISDN user / network interface is a so-called "connection oriented" in which an outgoing connection is made from one side to transmit and receive data.
The charging control of the communication network usage fee (communication fee) is usually a calling-side charging in which the communication network usage fee is calculated based on the incoming cell amount of the receiving side and is charged to the calling side.

However, inconveniences may occur in the calling side charging system, and the prior art includes a method borne by the called side, a method of switching to the called side at the request of the called side, and a method of arbitrarily switching the user between the calling side and the called side. It has been disclosed.

[0004] For example, Japanese Patent Application Laid-Open No. 5-344237, "I
In the “SDN charging destination switching method”, the charging destination switching request information is transmitted via the D channel using the charging destination switching request information transmission unit of the receiving terminal during a call. The ISDN exchange receives and analyzes the switching request information by the D channel reception analysis unit, switches from the calling side charging to the receiving side charging by the charging destination changing unit, and controls the charging information database. The charging destination can be switched to the receiving side at the request of the receiving side during a call using the terminal (referred to as first prior art).

[0005] Japanese Patent Application Laid-Open No. 7-107200 discloses "IS
In the "DN communication terminal device", information on the communication terminal device which is a target of the predetermined receiving-side service is registered, and this is temporarily denied for an incoming call from the registered communication terminal, and returned. The configuration is such that a call setting request is made to this communication terminal, and a service in which the called party bears the communication charge for a specific calling communication terminal device in ISDN is possible (referred to as second prior art).

Further, in Japanese Patent Laid-Open Publication No. Hei 7-212500, "Charging control system", in charging control of a communication fee for communication between a calling terminal and a called terminal connected via an ISDN network, the charge control is performed during communication. When information indicating that the charging rate between terminals for the communication fee is changed to a specific ratio is transmitted from one of the terminals to the charging center of the ISDN network, the communication fee after the transmission is specified. It is configured to charge the calling side terminal and / or the called side terminal according to the ratio, so that the user can arbitrarily change the billing contents for the calling side and the called side during communication (referred to as a third prior art). .

[0007]

As described above, the conventional I
In a data communication system using the basic interface of the SDN user / network interface, a communication fee is usually charged to a calling side, and the first and second prior arts can bear a communication fee. In some cases, it is preferable that both parties be charged at a fixed rate. For example, when the collect call method is simply used in a company's product information providing service or the like, there is a case where a communication fee is mischievously imposed on the receiving company.

[0008] In this case, in the third prior art, information to change the charging rate is transmitted, and the charging center can be controlled by this information. However, a charging center is provided, and a system for controlling the charging center and a user are required. Operation is required.

The present invention has been made in order to solve such a problem. The terminal-side user does not need to perform any operation with a simple configuration, and regardless of the amount of communication and the length of communication time,
It is an object of the present invention to provide a data communication system using a basic interface of an ISDN user / network interface which can charge a communication fee at a fixed rate to both a calling side and a called side.

FIG. 1 is a block diagram showing one embodiment of a device configuration used for the data communication system of the present invention. In the figure, 1 is a transmitting terminal device, 2 is a data traffic / communication time information storage means, 3 is a data traffic / communication time monitoring means, 4 is a B channel (information channel) switching means, 5 is a memory unit, 6 , 7 are the B channel (information channel), 8 is the D channel (control channel), and 9 is the I channel.
An SDN network, 10 is a terminating terminal device, 11 is a data traffic / communication time information storage means, 12 is a data traffic / communication time monitoring means, 13 is a B channel (information channel) switching means, and 14 is a memory unit. . Note that, as shown in FIG. 1, the transmitting side terminal device 1 and the receiving side terminal device 10 have the same configuration, and in FIG. 1, for convenience of explanation, the terminal device 1 is the transmitting side and the terminal device 10 is the receiving side. In addition, each terminal device 1, 10
Has a communication function necessary for actual communication, but is not directly related to the present invention, and is omitted in the drawings.

As shown in FIG. 1, the terminal devices 1 and 10 include:
Memory units 5 and 14 are provided.
4, using the storage means 2 and 11, the communication fee is set on the transmitting side,
The threshold value information of the data communication amount or communication time to be imposed on both the receiving side at a fixed rate is registered. That is, when the data communication amount or the communication time exceeds the predetermined amount or the predetermined time, the threshold value of the communication amount or the communication time for switching the communication charge from the calling side to the called side is stored in the memory unit 5 using the storage means 2 and 11. Register to 14. The monitoring means 3, 12
When the actual data communication is started, it is monitored whether or not the data communication amount or the communication time exceeds the threshold value based on the above-described threshold value. If the threshold value is exceeded, the information is switched to the B channel. Send to means 4 and 13. B channel switching means 4, 1
3 performs an operation of switching the currently connected B channel (B channel 6) to another B channel (for example, B channel 7) based on this information.

Next, the operation will be described. At the time of outgoing call, the calling terminal device 1 sets the threshold of the communication amount or communication time registered in the memory unit 5 in the user / user information of the call setting message,
A channel setting request for requesting connection processing for communication using channel 6 is transmitted. The receiving-side terminal device 10 stores the threshold value of the communication amount or communication time transmitted by the user / user information of the call setting message at the time of the incoming call in the memory unit 14 and completes the connection process.

Then, from the time when the data communication using the B channel 6 is actually started, the receiving terminal device 10 uses the data traffic / communication time monitoring means 12 to monitor the traffic or communication data stored in the memory unit 14. The monitoring of the actual traffic or the communication time is started based on the time threshold, and when the actual traffic or the communication time exceeds the threshold, the B channel switching means 13 is operated to activate the calling terminal.

Upon receiving the connection request to the B channel 7, the originating terminal device 1 stores in the memory unit 5 the threshold value of the communication amount or communication time transmitted by the user / user information of the call setting message. , B channel 7 are connected. When the connection of the B channel 7 is completed in the calling terminal device 1, the data communication is performed in both the calling terminal device 1 and the called terminal device 10 from the initially connected B channel 6 to the subsequently connected B channel 7. Switch. The originating terminal device 1 shuts off the B channel 6 connected first, and monitors the communication amount or communication time of data communication on the B channel 7 by checking the communication amount or communication time transmitted from the receiving side terminal device 10. Start with a threshold of Subsequent operations are the same as those of the receiving-side terminal device 10 described above. Then, during data communication, such a process is alternately repeated on both sides.

That is, during data communication, B channel 6 →
The communication channels are automatically switched in the order of B channel 7 → B channel 6 →... Based on the threshold values registered in the memory units 5 and 14, respectively. Since the calling side is charged and the communication fee is charged to the called side during communication on the B channel 7, a fixed rate is applied to both the calling side and the called side irrespective of the amount of data communication and the length of communication time. It becomes possible to impose a communication amount.

The ratio of the communication fee charged to both the calling side and the called side is determined by the threshold values registered in the memory unit 5 and the memory unit 14. If both threshold values are the same, the data communication amount and Irrespective of the length of the communication time, both the calling side and the called side can have substantially the same charge.
Further, for example, a threshold value of about one minute is registered in the memory unit 5 of the calling terminal device 1, and the memory unit 1 of the called terminal device 10 is registered.
By not registering a threshold value in No. 4, inconveniences such as improper charges being charged to the calling side when the call waiting function is used are eliminated.

The threshold values registered in the memory unit 5 and the memory unit 14 may be any one of the threshold value for the data communication amount and the threshold value for the communication time, or both of them. Needless to say. Further, in the above-described embodiment, the transmitting terminal device 1 and the receiving terminal device 10
Although the configuration to register the threshold value in both has been described,
The configuration is such that the threshold value is registered only in the transmitting side terminal device 1, only the receiving side terminal device 10 can transmit a B channel switching request to the transmitting side terminal device 1, and the data communication amount or communication time When the predetermined time is exceeded, the communication amount exceeding the communication amount or the communication time for the communication time can always be borne by the receiving side.

[0024]

As described above, according to the data communication system of the present invention, data communication is performed by alternately connecting two B channels from each other during data communication based on the respective thresholds. Regardless of the amount or the length of the communication time, it is possible to charge a communication fee to both parties at a fixed rate. In addition, there are effects such as the necessity of providing a billing center and not forcing the user to operate.
