Communication terminal signaling box for tri-networks integration system

Abstract

The invention is suitable for the communication field and provides a communication terminal signaling box for a tri-networks integration system. The communication terminal signaling box comprises a central controller, and a terminal signaling platform, a switch unit, a network card, a public switched telephone network (PSTN) network interface / wireless communication interface and a voice processing module, which are connected with a central controller. The switch unit comprises three switch ports, wherein a first port is connected with the PSTN network interface / wireless communication interface, a second port is connected with the network card, a third port is connected with an external communication terminal through the voice processing module, and any two of the three switch ports are controlled by the central controller to be communicated. In the interaction between the built-in terminal signaling platform of the communication terminal signaling box and the operation equipment signaling platform of an operation terminal, all or partial communication paths are realized by using internet passages; therefore, communication cost among communication terminals within three networks islower, even free.

Description

technical field [0001] The invention belongs to the communication field, in particular to a communication terminal signaling box 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 extremel...

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 communication terminals as an example, although traditional PSTN fixed network communication terminals and mobile communication terminals have very good advantages such as reliability, manageability, and operability, they have revealed many shortcomings under the impact of the rapid development of the Internet. From the user's point of view, the most direct feeling is that the phone bill is expensive, but from the operator's point of view, the operating cost is too high
