Telephone terminal for three-network integration system

Abstract

The invention provides a telephone terminal for a three-network integration system, which is suitable for the communication field. The telephone terminal comprises a central control unit and a terminal signaling platform, a switching unit, a network card, a fixed network interface / radio telephone network interface of a public switched telephone network (PSTN) and a dialing and voice processing unit which are connected with the central control unit, wherein the switching unit is provided with three switching ports, wherein the first port is connected with the fixed network interface / radio telephone network interface of the PSTN, the second port is connected with the network card, and the third port is connected with the dialing and voice processing unit; and the central control unit controls any two of the three switching ports to be switched on. The terminal signaling platform arranged in the telephone terminal and an operating equipment signaling platform at the operating end establish connection between the telephone terminal and other terminals in the system through interaction, and all or partial communication paths are realized by Internet channels, so that the telephone charge of communication among telephone terminals in three networks is lower, and even the communication can be toll-free.

Description

technical field [0001] The invention belongs to the communication field, in particular to a telephone terminal used in a triple network integration system. Background technique [0002] Triple play (Internet, TV network, telephone network) has gone through ten years of history, and countries all over the world have adopted the IP Multimedia System (IP Multimedia Subsystem, IMS) scheme proposed by Alcatel, Lucent, Nokia, etc. to carry out. The basis of the IMS solution is that the Internet is unmanageable, uncontrollable, and unoperable, so it is necessary to develop a large number of devices to transform the existing network, and the fact that the Internet itself is constantly developing makes the research of IMS unable to keep up with the development of the Internet. . At the same time, the IMS still retains the physical network of the Public Switched Telephone Network (PSTN), so a large number of gateway groups must be added, which makes the IMS extremely complex and diff...

Problems solved by technology

The basis of the IMS solution is that the Internet is unmanageable, uncontrollable, and unoperable, so it is necessary to develop a large number of devices to transform the existing network, and the fact that the Internet itself is constantly developing makes the research of IMS unable to keep up with the development of the Internet.

At the same time, IMS still retains the physical network of the Public Switched Telephone Network (PSTN), so a large number of gateway groups must be added, which makes IMS extremely complicated and difficult to operate and use

[0003] Taking the telephone terminal as an example, although the traditional PSTN fixed-line telephone terminal and mobile telephone terminal have very good advantages such as reliability, manageability, and operability, under the impact of the rapid development of the Internet, many problems have been revealed. Insufficient, from the user's point of view, the most direct feeling is that the call fee is expensive, and from the operator's point of view, the operating cost is too high
