Abstract

PROBLEM TO BE SOLVED: To easily make a request for exclusive communication without knowing mutual identification codes and to protect privacy in order for two terminals which are in the process of communication with a band shared communication network to monopolize a fixed band and to communicate. SOLUTION: A terminal 1 of a communication subject sends an information transmitting and receiving request signal to a terminal 4 via a band shared communication network 5, and the terminal 4 sends a line connection request signal to a service controller 3 via the network 5. The controller 3 extracts an identification code in a line switching communication network 6 from a storage device 11 based on received identification codes and sends an intra- network call out request signal to an exchange device 2. The device 2 carries out connection processing between the terminals 1 and 4 in the network 6 based on the received identification codes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band sharing communication network in which a plurality of users share a common transmission band as seen in the Internet communication. The present invention relates to a circuit-switched connection service control device that can occupy and transmit and receive information.

[0002]

2. Description of the Related Art Conventionally, when a plurality of users communicate with each other via a shared bandwidth communication network sharing a common transmission band as seen on the Internet, the information transmission speed is generally limited to that of other users. It is uncertain because it is affected by the situation. Further, since the bandwidth is shared with other users, transferring a large amount of information will affect the communication of other users. In order to avoid such an effect, it is possible to use a circuit-switched communication network which can secure a certain band and occupy a certain bandwidth, but in that case, one terminal uses the circuit-switched communication network of the other terminal. He had to know the identification code (eg, telephone number) and place a call to that circuit-switched communication network.

[0003]

As described above, conventionally, in a communication network such as the Internet where a plurality of users share a band, in order to occupy a certain band, one terminal must be connected to the other terminal. It is necessary to inquire about the identification code such as a telephone number, and to make a call to the circuit-switched communication network after obtaining the identification code. Therefore, an object of the present invention is to solve such a conventional problem, and to allow a terminal to communicate between terminals communicating in a band sharing communication network without knowing the identification code of the other terminal. An object of the present invention is to provide a circuit-switched connection service control device that can be connected by a switching communication network.

[0004]

In order to achieve the above object, in a circuit switching connection service control apparatus according to the present invention, a terminal communicating via a bandwidth sharing type communication network uses a circuit switching communication network together. When performing communication, the storage device in the service control device in the circuit-switched communication network holds information for associating the terminal identification code in the band-shared communication network with the terminal identification code in the circuit-switched communication network, It is characterized in that the connection is made without knowing the mutual identification code in the circuit-switched communication network by transmitting and receiving control information by connecting the service control device and the shared bandwidth communication network.
Accordingly, when it is desired to transmit and receive information while occupying the band, both terminals do not need to make a call to the circuit-switched communication network, and therefore need to recognize the mutual identification codes of the terminals in the circuit-switched communication network. There is no.
