Communication system

Abstract

The invention relates to a communication system, which comprises an access server and several client exchangers, wherein the exchangers are connected to the server via public network as internet; different areas of exchanger are connected to attached telecommunication networks; when two users need remote communication, user can input recognize code of receiver communicator on the client exchanger, therefore, the access server can via said recognize code search out another client exchanger met the receiver communicator; and said client exchanger can search for and connect the receiver communicator on its telecommunication network, and the user can connect the receiver communicator via the public network and the telecommunication network of receiver communicator, to save cost.

Description

technical field [0001] The present invention relates to a communication system, especially a communication system, which is composed of a login server and a plurality of client switching devices. Background technique [0002] A general traditional communication system includes multiple telecommunication networks (such as: Public Switched Telephone Network (PSTN), GSM, PHS, etc.), and these telecommunication networks are divided into different regions (such as: geographical area) (such as: Taiwan, the United Kingdom and Egypt... etc.), system areas (such as: GSM, PHS and PACS... etc.) or service providers... etc.), and each of the telecommunications networks and their respective Communication devices in corresponding areas (such as indoor phones, public phones, mobile phones, etc.) are connected together so that any communication device can find and connect to another communication device on the telecommunication network through its telecommunication network, enabling the us...

Problems solved by technology

[0004] However, in the traditional communication system, when users located in two different regions (for example: Taiwan and Egypt) want to conduct long-distance communication, one of the user's communication devices must first be connected to the local telecommunications network, and then through A plurality of routing devices 90 are switched one by one in the telecommunications network of each region, and are not connected to another user's communication device until they are switched to the local telecommunications network where the other user's communication device is located, resulting in Due to the complicated transfer process, the cost of the call is too high, and the communication quality is also unstable. Therefore, how to design a communication system design can take advantage of the characteristics of the current Internet, which is far-reaching and low-cost, to effectively save money. Communication cost is an important issue that needs to be solved without delay
