Internet mobile phone system using standard mobile phone communication network

The present invention relates to a communication system, and more particularly, to a mobile phone communication system using a mobile phone communication network that controls a communication network to enable a general mobile phone call and Internet phone call to a mobile phone using a conventional mobile phone communication network.

With the development of communication technology, the telephone communication technology using the Internet is spreading widely, and the spread of cellular mobile communication is rapidly increasing to overtake the landline telephone. Recently, technology development of internet mobile phones, which supports the advantages of internet phones and mobile phones, is also a global concern.

There are two ways to make a phone call using internet phone technology in a home.

First, there is a method of using an internet phone using a computer.

When using an Internet phone with a computer, an IP address is assigned by connecting to an Internet Service Provider (ISP) using Point to Point Protocol (PPP), a modem and software for Internet access. By completing preparation for TCP / IP to run, it is possible to connect to the other host for the voice call. Subsequently, when the PC user attempts to connect to the called party by running the Internet phone program and the other party answers, the voice call is connected and the telephone call can be made.

Second, there is a method using an internet phone.

If you are using an Internet phone, instead of running your computer, connect your Internet line to your Internet phone, enter your subscriber ID and set up your gatekeeper information once, and you will be ready to use it like a regular phone. Free calls can be made to Internet phones, and at the same time, Internet phone service companies can make inexpensive calls from Internet phones to regular phones.

In recent years, the popularity of cellular mobile communication has been increasing, and the concept of a telephone is changing from a wired communication to a mobile phone using wireless communication.

Since mobile phones are mobile and convenient to receive communication wirelessly, most families own and use mobile phones, and because of their convenience, it is a reality to use mobile phones even with public phones. With the development and development of contents, the use of mobile phones is continuously increasing. In the early stages of distributing mobile phones, there were many areas where calls were not made due to the lack of base stations installed all over the country, but in recent years, all these problems have disappeared. On the contrary, TV functions and camera functions are also embedded in mobile phones. It is entering the era of mobile phone universals by paying fees and replacing ordinary bank accounts with mobile phone accounts.

As such, Internet phone has the advantage of free or very low call rate, but you need to purchase a separate device, apply for Internet such as ADSL / VDSL and cable modem, and pay monthly Internet usage. Difficult to understand is an obstacle to the dissemination of Internet phones, and in recent years, because everyone is using more mobile phones than regular phones, disseminating Internet phones to those who are familiar with mobile phones can also be a problem. Internet mobile phone technology using the Internet has also been developed, but the price of the device is still very high, and the area using the wireless Internet is extremely limited, and the wireless Internet can be used only at a short distance. There was a problem.

As described above, according to the related art, first, in order to make a phone call with an internet phone in a long distance or a foreign country, there is a disadvantage of having to go through several levels of communication company networks.

Secondly, the Internet phone can be used only in limited places where wired and wireless Internet systems are built.

Third, in order to use a wireless internet phone, a wireless internet repeater must be widely distributed, and a wireless internet phone must be developed and popularized at a realistic price. The technologies developed so far are the price of wireless internet repeaters and wireless internet phone terminals. Since this is very high, there are limitations in securing a subscriber.

Fourthly, in order to use a wireless internet phone in a moving car, there is a disadvantage in that a wireless internet service having a roaming function must be provided.

Fifthly, in order to use an Internet telephone, all subscribers, such as individuals and companies, apply for an Internet line individually and require an internet communication device such as an internet modem, an internet telephone, or a gateway.

The technical problem to be solved by the present invention is to solve the above problems and disadvantages by interworking the mobile phone exchange system and the Internet phone system through the gateway, and set the Internet phone number of the same system to the mobile phone and the Internet phone to the Internet phone Not only can you make a phone call from an Internet phone to a mobile phone in the same way that you can make a phone call, but when you make a call from a mobile phone to an Internet phone, The present invention provides an internet mobile communication system using a mobile communication network.
