Abstract

PURPOSE:To automatically select a line of a company offering the cheapest connection charge from a specific district to an optional object district by using a card having a line identification number of the company offering the cheapest charge corresponding to an object district as information. CONSTITUTION:When a card 101 having line selection information 102, i.e., information of an identification number of a line of a company offering the cheapest charge corresponding to a toll number is loaded, a read section 103 reads the line selection information 102 from the card. Then a control section 106 extracts only a toll number from dial information and a readout control section 107 selects a company identification number offering the cheapest line from the toll number and the line selection information in the read section 103 and a number addition section 109 adds a selected and outputted company identification number 108, to a head of dial information and the result is outputted to an exchange. Thus, the line of the company offering the cheapest connection charge from a specific district to an optional object district is automatically selected only by loading the card onto a telephone set and dialing a telephone number.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses a card telephone and a card connected to lines of a plurality of line carriers, selects a specific line from the plurality of lines, and connects the line. This relates to a line selection method that performs.

[Conventional technology]

Currently, in 8 lines, line services are being started by multiple line carriers between relay exchanges, but from among the multiple line carriers, it is possible to use the line of a specific carrier from among the multiple line carriers from a telephone that does not have a contract with a line carrier. cannot be selected. On the other hand, in the United States, it is already possible to select and connect to multiple line carriers from any phone without having to contract with a line carrier.
It is possible that this will become possible in our country in the future.

Currently, one way to automatically select a line from a telephone that has contracts with multiple line carriers is to connect a low-cost line identification adapter to the telephone. This low-cost line identification adapter is a device that automatically selects and connects to the cheapest line from multiple line carriers.

[Problem to be solved by the invention]

As mentioned above, if an environment is established in which users can freely connect to lines of multiple line carriers without having to contract with them, when they try to make a call, they will first need to use the low-cost line identification adapter ( One possible method is to select a line by connecting an adapter (hereinafter referred to as an adapter) to a telephone, but with this adapter,
It requires a function to convert the dialing information input by the user into dialing information for the selected line and send it to the telephone set, and the dial input section and transmitter need to be built into the adapter, making the device larger. The disadvantage is that it is inconvenient to carry. Another possible method is to provide a line selection function inside the telephone.

In this case, since all users can receive the line selection service, it is not possible to provide the line selection service only to specific users. Another disadvantage is that it is troublesome to change the line selection information inside the telephone set for each telephone set in response to revisions to trunk line charges.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a line selection method that can automatically select a line of an operator with the cheapest connection fee from a specific area to an arbitrary destination area.

[Means to solve the problem]

In order to achieve the above object, the present invention uses a card telephone connected to a network made up of lines of a plurality of trunk line carriers, and when connecting from a specific area to an arbitrary destination area, the plurality of In the concave line selection method in which a specific line is selected from among the lines and a connection is made, the card used in the card telephone has as information the operator identification number of a specific operator that corresponds one-to-one to the destination area, and the card The telephone includes a card reading unit that reads information from the inserted card, a control unit that reads the business identification number from the card based on the area code dialed by the user, and a control unit that reads the business identification number from the card based on the area code dialed by the user. and a number addition unit that adds the information to the dialed information and sends it to the line, and by inserting the card into the card telephone and dialing the card, the user who owns the card can travel from a specific area to a destination area. The system is characterized by automatically selecting a relay line of a specific carrier when connecting.

[For production]

The present invention allows users to travel from a specific area to any destination area by simply inserting a cart into the card phone and dialing a phone number if the phone the user is trying to use is connected to multiple line carriers. Since the line of the carrier with the cheapest connection fee can be automatically selected, the user is freed from the troublesome task of selecting an inexpensive line, and since it is in a card format, it is convenient to carry. It has the advantage that users can be limited, value can be added to the cart, and line selection information can be easily changed in response to a revision of line charges by exchanging cards. Embodiments of the present invention will be described below based on the drawings.

106 is a control unit that extracts a long-distance phone number from the dialing information; 107 is a reader that outputs a carrier identification number 108 based on the long-distance number outputted from the control unit 106 and the line identification information in the reading unit 103; 108 is a carrier identification number output from the reading control unit 107, and 109 is a number addition unit that adds the carrier identification number 108 to the beginning of dial information to generate new dial information and outputs it to the exchange. .

FIG. 2 is a flowchart illustrating an example of line connection operation in a line selection method according to an embodiment of the present invention.

FIG. 3 shows an example of the final connection configuration when the present invention is implemented.

In FIG. 3, 301 is a card with line selection information, 302 is a card telephone, 303 and 304 are relay exchanges, 305, 306, and 307 are lines provided by the respective line carriers, and 308 is the line that is finally selected. The final selected line route 309 is a general telephone set on the receiving side. The operation of this embodiment will be described below in accordance with the flowchart in FIG. 2 and with reference to FIG.

The card telephone 100 is turned on-hook (step 201), and the card is inserted (step 202). The reading unit 103 reads the line selection information 102 from the inserted card (step 203), and the card telephone 100 transmits the on-footer information to the exchange (step 204).
