Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an ISD for connecting a terminal device to an ISDN network by having a communication charge calculating means and converting a non-ISDN interface and an ISDN interface.
The present invention relates to an N communication processing device.

[0002]

2. Description of the Related Art A conventional ISDN communication processing device does not have a means for calculating a communication charge, but has only a means for displaying a charge notification provided by an ISDN network when a circuit switching service is provided. .

The ISDN switching services (circuit switching service and packet switching service) have a time charging system in which the distance between communication points and the time occupied by the circuit are charged, and the amount of data transmitted and received regardless of the time of communication. We use a very different billing method called the pay-as-you-go billing method.

[0004]

However, in recent years,
When constructing an in-house network, the number of cases where ISDN is incorporated into the network is increasing, and a network person in charge is required to make various types of communication in order to determine which exchange service is cost-effective at the time of constructing the network. The information (distance between communication points, communication time, data amount, etc.) has to be collected, and there is a problem that it takes a very long time.

The present invention solves the above-mentioned problems, and is provided with a simple communication charge calculation means when selecting an exchange service.
An object is to provide an SDN communication processing device.

[0006]

In order to achieve the above object, the present invention transmits and receives a communication time calculating section for calculating a communication time, a data calculating section for counting the number of transmitted and received data. A packet counter for counting the number of packets and a charge table for calculating a communication charge are provided.

[0007]

According to the present invention, with the above configuration, in addition to the charge display in the circuit switching service, the charge calculation in the packet switching service can be performed. Also, the currently used switching service (circuit switching service or packet switching service)
It is also possible to pseudo-calculate the communication charge when using a switching service different from the above (a packet switching service if the circuit switching service is currently used) and notify the user.

[0008] Therefore, which exchange service is more cost effective is determined by a very simple method in which communication is performed once by any exchange service without collecting various information when constructing a network. be able to.

The ISD of this embodiment configured as described above
The operation of the N communication processing device 12 will be described below with reference to FIGS. 2 to 4.

FIG. 2 is a flow chart showing a series of processing relating to charge calculation during packet communication. First, in step 21, it is determined whether it is a transmission process or a reception process. In the case of the transmission process, the process proceeds to step 22, and in the case of the incoming process, the process proceeds to step 23. Step 22 is processing at the time of transmission, packetizes the data received from the data terminal, and proceeds to step 23. Step 23 is a process of counting the number of packets, and sequentially counts the number of transmission packets packetized during transmission and the number of reception packets received during communication. In step 24, it is determined whether the communication has ended. If the communication has not ended, the process returns to step 21, and the number of transmitted / received packets is counted again. When the communication is completed, the process proceeds to step 25. In step 25,
Calculate the distance information between communication points by the telephone number of the communication partner stored in the memory and your own telephone number,
The communication charge per packet is calculated from this distance information and the maximum packet length stored in the memory. By multiplying this by the total number of transmitted / received packets, the charge for packet communication can be calculated.

FIG. 3 is a flow chart of a series of processes for pseudo-calculating a charge when using another service (packet switching) by using the circuit switching service. First, in step 31, it is determined whether it is a transmission process or a reception process. If it is a transmission process, the process proceeds to step 32, and if it is an incoming process, the process proceeds to step 33. Step 32 is processing at the time of transmission, packetizes the data received from the data terminal, and proceeds to step 34. Step 33
Is a process at the time of reception, packetizing the data from the partner terminal received via the ISDN network and proceeding to step 34. Step 34 is a process of counting the number of pseudo packetized transmission / reception data, and sequentially counts the number of transmission packets packetized from the transmission data and the number of reception packets packetized from the reception data. Step 35
Then, it is determined whether the communication is completed. If the communication is not completed, the process returns to step 31, and the number of packetized transmission / reception data is counted again. When the communication is completed, the process proceeds to step 36. In step 36, the distance information between the communication points is calculated by the telephone number of the communication partner stored in the memory and the telephone number of itself, and from this distance information and the maximum packet length stored in the memory, Calculate the communication charge per packet. By multiplying this by the total number of packetized transmission / reception data, the communication charge when using the packet switching service can be calculated in a pseudo manner.

FIG. 4 shows that a packet switching service is used.
It is a flow chart about a series of processings for quasi-calculating a charge when using another service (circuit switching).

First, in step 41, it is determined whether the process is a transmission process or a reception process. If it is a transmission process, the process proceeds to step 42, and if it is an incoming process, the process proceeds to step 43. Step 42 is processing at the time of transmission, counting the number of data received from the data terminal and proceeding to step 44. Step 43 is a process at the time of reception, and after decomposing the received packet from the partner terminal received via the ISDN network to count the number of received data, the process proceeds to step 44. In step 44, it is determined whether the communication has ended. If the communication has not ended, the process returns to step 41, and the transmission / reception data counting process is performed again. When the communication is completed, the process proceeds to step 45. In step 45, the full-duplex communication or the half-duplex communication is determined by referring to the communication method stored in the memory. Step 46 is a process for full-duplex communication. In the full-duplex communication, since the transmission process and the reception process can be executed at the same time, the communication time is equal to the transmission / reception time of the transmission data or the reception data having the larger data amount. Therefore, compare the number of transmitted data and the number of received data, select the one with the most data as the data to be processed,
Go to step 48. Step 47 is a process for half-duplex communication. Since half-duplex communication is a method in which transmission processing and reception processing are executed alternately (cannot be executed at the same time), the time required for communication is the total number of transmitted data and the number of received data transmitted / received. Is equal to time. Therefore, the total number of transmitted data and the number of received data is selected as the data to be processed, and the process proceeds to step 48.
Step 48 is a charge calculation process. Since the circuit switching service is a time charging system as described above, the communication charge is determined by the distance between communication points and the time of communication.
The communication distance is calculated from the telephone number of the other party stored in the memory and the telephone number of oneself. Communication time is
It can be calculated by the communication speed and the amount of data communicated. Therefore, the communication time is calculated by dividing the number of data to be processed calculated in the previous step by the communication speed stored in the memory. Further, based on the communication distance information and the communication time information, the communication charge for using the circuit switching service can be pseudo-calculated from the charge table.

As described above, according to the above-described embodiment, the communication time calculating unit 9 for calculating the communication time, the data counting unit 5 for counting the number of transmitted / received data, and the number of transmitted / received packets are counted. Since the packet counting unit 8 and the charge table 10 for calculating the communication charge are provided,
In addition to displaying charges for circuit switching services, it is possible to calculate charges for packet switching services. Also, the communication charges when using a switching service (a packet switching service if the circuit switching service is currently used) different from the currently used switching service (circuit switching service or packet switching service) are simulated. It is also possible to calculate and notify the user.

[0016]

As is apparent from the above embodiments, the present invention can not only calculate the charge for packet communication in ISDN, but also use the line switch service to calculate the charge for packet switch service. Since the charges for the circuit switching service can be calculated in a pseudo manner using the packet switching service, the user can use the ISDN
When constructing a network using, the cost of communication can be known by the extremely simple method of performing communication once, depending on the environment (exchange service) currently used.
