Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trunk line selection and connection system, and more particularly to a system for selecting a trunk line in a line connection of a communication network in accordance with a user's preference and connecting the line.

[0002]

2. Description of the Related Art From October 30, 1996, a service for interconnecting a public network and a dedicated line to provide communication has been licensed.
(The so-called "public-public" connection service was lifted.) In this regard, for example, the articles of Telecommunications December 1996, January 1997, and February 1997 can be referred to. At present, when a public network and a dedicated line are interconnected to perform communication, a telephone number of a dedicated line access point, a user number, a password if necessary, and a destination telephone number are input. Communication with the other party has been established. In order to avoid inputting a large number of numbers as described above, a dedicated adapter is attached to a user terminal. On the other hand, the use of another communication network as a trunk line is also actively performed. In this case, the access number (0080, 0088, etc.) to the other communication network is manually or automatically (LCR device) and the destination user number is used. Has been added.

[0003]

However, the conventional technology has drawbacks in the following economical aspects and service limitations. (1) As described above, it was necessary to input a number of numbers other than the telephone number of the other party. (2) The adapter to be attached to the user terminal described above dials the number of the dedicated line access point in a fixed manner. Therefore, when the adapter is attached to the user terminal to simplify the number input, various dedicated line resellers are required. This could not be selected, which limited the choice of trunk line that the user could select. (3) Further, in the above-mentioned conventional technology, the communication cost between the access points of the leased line reseller can be reduced, but a normal telephone line must be used from the access point to the destination, and a plurality of leased line resellers are required Could not be connected in multiple stages. Therefore, the trunk line could not be used more economically. (4) There is a device (LCR device) that selects the optimal other communication network (long-distance communication carrier) and automatically adds the access number to the other communication network to the called number. Lines cannot be used. The present invention has been made in view of the above circumstances, and its purpose is to solve the above-described problems in the prior art, appropriately select various dedicated line resellers and the like by the destination telephone number, An object of the present invention is to provide a user with a simple line connection service that automates the input of a large number of numbers, and to enable multistage relay line connection.

[0004]

In order to achieve the above object, in the invention according to claim 1 of the present invention, means (210, 220) for selecting a trunk line and inputting a number of numbers are provided in a network. It is characterized in that an appropriate trunk line is selected at the time of a call setting request from a user, and if necessary, a number is automatically input by a PB signal or an access number to another communication network is automatically added. This allows the user to perform economical line setting with a simple operation.
