Management system

Abstract

The invention provides a management system, which can solve the problem, wherein when being directly connected to an IP network from a subscriber accommodation device, without interposing a PSTN (public switched telephone network), at a connected destination, voices or data cannot be discriminated from a called number distributed by an exchange inside a conventional PSTN network and in the case where the IP network includes a subscriber network, each user utilizing an analog line and an ISDN (integrated services digital network) line cannot utilize a voice call or data communication. A table is used for registering and managing subscriber information such as information indicating whether the ISDN line or an analog line or a TS (time slot) of which HW (high way) in a time dividing switch (TSW) of a media gateway (management apparatus) is to be utilized for connection or information, indicating a service that a subscriber contracts.

Description

technical field [0001] The present invention relates to a media gateway that provides means for connecting users using voice calls and data communications to an IP network using a conventional ISDN (Integrated Services Digital Network: Integrated Services Digital Network) line. Background technique [0002] In recent years, the conversion to the next generation network ((NGN) Next Generation Network) has progressed, and the all-IP (Internet Protocol: Internet Protocol) of the network has also been developed. In the trend toward all-IP (Internet Protocol), the Public Switched Telephone Network (PSTN: Public Switched Telephone Network), which accommodates analog lines and ISDN (Integrated Services Digital Network) lines, is no longer out of the trend. In addition, in accordance with the above-mentioned trend, in the Public Switched Telephone Network (PSTN: Public Switched Telephone Network), conversion of a trunk network including a trunk switch to an IP (Internet Protocol) ne...

AI Technical Summary

Problems solved by technology

Therefore, when the subscriber accommodating device is directly connected to the IP network without going through the PSTN, the subscriber accommodating device will not be able to identify whether the communication partner is a voice terminal or a data communication terminal based on the incoming call number.

Therefore, there is a problem that it is impossible to determine whether the connection destination is voice or data based on the incoming call number assigned by the switchboard in the conventional PSTN network.

In addition, when the subscriber network is also formed as an IP network, there is a problem that each user using an analog line or an ISDN line cannot use voice calls or data communications.

[0013] In addition, when the subscriber switch in the PSTN network is connected to the media gateway (MG), and then the data communication between the user terminal and the Internet is performed through the IP network, it is necessary to use the interface UNI connected to the Internet to return the data from the IP network to the PSTN network, so there is a problem that the PSTN network must be preserved
