The present invention relates to mobile phone roaming, and in particular, by registering to the call forwarding additional service provided by the telecommunications company and by setting up a separate incoming telephone number for the incoming telephone number registered in the Internet telephone user ID in the Internet phone server using the Internet phone It relates to a mobile communication roaming system that can bring the effect of roaming mobile phones.
In general, an Internet phone is also called an Internet telephone or a Voice over Internet Protocol (VoIP) phone, and refers to a system or service that is used like a normal telephone by transmitting and receiving voice over the Internet.
Roaming service is a service that extends the quality and scope of services by cooperating with telecommunications companies. Overseas roaming is a domestic mobile telecommunications company that provides mobile phone services in partnership with overseas telecommunications companies. You will also be charged. However, for SMS text service, the reception is free.
Roaming is basically divided into automatic roaming, which takes its own cell phone, and rental roaming, which rents a cell phone at an airport roaming center. In case of automatic roaming, you can use the phone you are familiar with abroad, but few countries are available. Therefore, most of the rental roaming, there is a way that you can use your phone number as it is in the roaming lease.
Most people use roaming when they need to use a mobile phone abroad. However, there is a problem that the burden is high because the overseas roaming cost is very expensive.
In general, roaming charges are classified into three categories: when calling from the same country from abroad, when calling from Korea, and when receiving a call. Of course, the cost is the highest when calling from abroad. And it is relatively inexpensive when making a local call.
Roaming charges vary slightly from region to region. In particular, in Europe, call charges from overseas to Korea are very expensive, but they are inexpensive when received. In addition, there are price differences between mobile operators in the same country. L carriers, for example, are cheaper than other carriers in China and Hong Kong, but more expensive in Thailand.
Roaming charges are usually announced with the lowest and highest prices. In Korea, the rate is applied differently depending on the time in foreign countries as telephone charges are discounted at night.
For roaming in foreign countries, the rate is specified in 1 minute increments. In Korea, the tariff is calculated every 10 seconds, while roaming is calculated in minutes. Therefore, even if you use only 1 second, you have to pay a 1-minute fee, there was a problem that the 1-minute fee is set even if you use the phone 10 seconds after receiving the wrong call.
In addition, when the caller ID service is not available overseas, such as rental roaming, there is a problem in that a fee that is not required to be paid after receiving an incoming call blindly occurs.
An object of the present invention is to provide a mobile communication roaming system that can replace the overseas roaming service with a high cost by implementing a service having the same effect as a mobile phone roaming service using an Internet phone.

As an example, the above call is connected to the service through the following process.
(1) A customer who uses a mobile phone, A (011-1234-1234), applies for a call forwarding supplementary service (usually a monthly fee of around 700 ~ 900 won).
(2) A call forwarding is set from A mobile phone to CDPhone service (or Internet phone service, VoIP service) access number B (070-1234-1234).
(3) When C (016-1234-1234) calls A, he is automatically forwarded to B.
(4) For a call forwarded from a CDPhone server (or an Internet phone server, a VoIP server),
(4) -1. The sender number (C) and the recipient number (A) are analyzed and extracted.
(4) -2. A person's setting is checked and the call is forwarded to an Internet phone with a call D (for example, 852-1234-1234 in the case of HK (Hong Kong)).
(4) -3. Caller D gets a caller's caller ID and the call is established.
When comparing the present invention and the existing overseas roaming service in terms of cost as follows.
In case of S communication company, the mobile phone used to roam automatically, and when receiving a mobile phone roamed in HK, the reception comes out about 880 won per minute.
However, in the present invention, when roaming using a CDPhone (or an Internet phone or VoIP service), a charge (1 minute = 90 won) from the A mobile phone to the CDPhone server B + the CDK to the HK phone D (1 minute = 40 won) = 130 won will come out.
That is, about 85% of the cost is saved.
