Method and System for Serving Communication between Number based Telephone and ID based Softphone

The present invention relates to a communication service method and system between a number-based telephone and an ID-based soft phone.

In general, a communication system is configured for the purpose of transferring voice and data between terminals. Such a communication system basically started from a system capable of providing a call service and has now evolved into a system of various types capable of providing a data service. Let's take a brief look at each system.

First, a system capable of providing a voice service is a typical type of telephone exchange system using an exchange for a wired terminal. The telephone exchange system for the wired terminal is a representative method of the circuit (Circuit) service. There is also another alternative telephone exchange system that can provide voice services. That is, a wireless telephone exchange system in which a terminal can be provided with a service wirelessly. In the service method using the wireless telephone switching system, since the 1980s, an analog method of providing a voice service has been commercialized, and now, a third generation (3rd) capable of high-speed data service as well as transmitting a voice signal using a digital signal is available. Generation) developed into a mobile communication system. In addition, in the form of a mobile communication system that can provide a higher speed data service, as well as mutual voice service, video call service has been commercialized and spread.

Meanwhile, even in a wireline telephone exchange system providing voice service, high-speed data service is possible due to the development of an intelligent network and the development of an asynchronous transmission mode (ATM) technology. As such, the technology of the wired communication system, which started from the wired telephone exchange system, has evolved significantly to meet the needs of users. As such, technological advances in wired communication systems have had a great impact on the spread of Internet services.

On the other hand, Internet telephony services are basically developing high speed data services, and video cameras are being developed at a low price as video cameras can be provided at low prices. Such an internet phone service has an advantage that it is much cheaper than a service based on a conventional phone number.

On the other hand, as a different concept from the number-based Internet telephone, there is an ID-based soft phone that provides a voice call service using a user identification (ID) of the Internet. In other words, unlike a number-based telephone using a telephone number as an identifier of a terminal, an ID-based soft phone provides a telephone call service using an ID. It can provide voice or voice and video at the same time as a typical number-based phone. However, since the ID-based soft phone provided by the Internet service is based on an ID using English letters or alphabets and numbers, it is not possible to provide a communication service between users of a general telephone communication system based on a phone number. In addition, it is not possible to provide a communication service between the user of the Internet telephony system and the user of the mobile communication system based on ID.
