Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to an automatic line selection type telephone terminal device that is connected to communication line networks of a plurality of companies with different fee structures and automatically selects the line network. (Conventional technology) In the past, only NTT was authorized to operate communications networks, but with the revision of the Telecommunications Business Law, the telecommunications business was liberalized in April 1985, and private companies were It has become possible to operate communication networks using the latest technology, and companies are trying to provide low-cost calling services using the latest technology. Therefore, if you use these companies' communications networks, you can receive call services at lower rates than if you use NTT's communications network, depending on the destination. How to connect to this non-NTT communication network is as follows.
A company identification number assigned to each company can be added to the conventional telephone dial. In other words, the conventional NTT telephone number was "0+
The structure is "Area code + Local code + Subscriber number", but when using a communication network other than NTT, it is composed of "Corporate identification number + Area code + Local code + Subscriber number". You can use the desired communication network by dialing the telephone number ``. (Problem to be solved by the invention) However, with the addition of a company identification number, the number of digits in a telephone number has increased, making dialing operations much more troublesome than before. The inconvenience is that you cannot use it unless you know the number. One way to avoid this hassle is to add a button to your phone to select which company's line you want to use.The user can press the button for the desired communication network, and then call the other party. It is also possible to consider a method in which when a number is dialed, the company's identification number and dial signal are automatically output. However, even with this method, the hassle of choosing which communication network remains,
Also, find out which communication network has the cheapest charges.
Users must make their own judgments on a case-by-case basis. In particular, it is relatively easy to select a line for a specific party with whom you make frequent calls once you get used to it, but if you do not know the other party's area well, you must be careful even when entering the telephone number. When calling someone for the first time, the above-mentioned line selection operation is extremely troublesome. The present invention solves the above problems and provides an automatic line selection type telephone terminal that automatically connects to a line with a lower rate by simply inputting a dial number for any communication party. The purpose is to provide equipment. (Means for Solving the Problems) In order to solve the above problems, the automatic line selection type telephone terminal device of the present invention has the following features: Indicates an area code, a local code, and a subscriber number in response to a dialing operation. A dialing device for outputting an arbitrary series of dialing signals, a dialing signal storage means for temporarily storing an arbitrary series of dialing signals in response to the dialing operation, and a unit of a plurality of communication line networks with different fee structures. Usage fee storage means having a usage fee table that stores usage fees per hour for each communication line network in advance in correspondence with each area code, and an identification number for identifying the plurality of communication line networks. identification number storage means for storing an identification number; dialed number identification means for identifying an area code in a dial signal temporarily stored in said dialed signal storage means; and said identification number identified by said dialed number identification means. a usage fee search means for searching the usage fee table per unit time for each communication line corresponding to the area code in the dial signal; a communication line network selection means that compares usage charges per unit time of each of the plurality of communication line networks and selects a communication line network with a low usage charge per unit time; an identification number storage means for reading out the identification number of the selected communication line network from the identification number storage means; and temporarily storing the identification number read by the identification number storage means into the dial signal storage means by the dial operation. and dial signal sending means for adding the dial signal to the beginning of a series of dial signals stored in the memory and sending the signal to the communication line. (Function) With this configuration, when the user inputs the telephone number of an arbitrary party, the automatic line selection type telephone terminal device of the present invention temporarily stores the dial signal and displays the telephone number's local number. The toll number is identified, and an inexpensive communication line network is selected from among the usage charges per hour of each communication line network corresponding to the toll number. Then, the identification signal of the selected communication line network is added to the beginning of the dial signal and output to the communication line. (Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention, in which a switch HS is connected to central lines L1 and L2.
a dial signal sending circuit 1 connected via;
A call circuit 2 that sends and receives call signals via the dial signal sending circuit 1 and a dial number signal corresponding to the operation of the numeric buttons on the keyboard 3 are input, and the charge information table for each line stored in advance is input. It consists of a control circuit 4 that searches for a line with a low charge, adds the identification number of the line to a telephone number, and outputs a control signal for sending out from the dial signal sending circuit 1. The control circuit 4 is composed of a stored program type arithmetic processing unit (CPU, for example, a microprocessor), and its internal ROM is used to control the contents as shown in the flowchart of FIG. programs are stored in RAM
As shown in Table 1, the usage fee per unit time of each company's communication network for each call destination corresponding to each area code of NTT's communication line network is NTT
The information is stored in advance in a table format so that it can be compared with the usage fee.
