Description

International roaming service system using internet and its method {INTERNATIONAL ROAMING SERVICE SYSTEM USING INTERNET AND METHOD THEREOF}

The present invention relates to an international roaming service system and method using the Internet.

In recent years, the number of foreign business travelers and foreign travelers has reached a considerable level, and the demand for calls anywhere, anytime, anywhere, has greatly increased. As a result, international roaming services between mobile communication companies have become more common. Subscriber is using.

However, many international roaming service users have excessive service charges, so they are not only receiving international roaming calls, but also do not receive roaming calls or refrain from using them themselves. Local incoming calls are additional roaming calls. You have to pay a fee.

On the other hand, the voice call service using mVoIP (Mobile Voice over Internet Protocol) technology has been developed for the reason that it is very inexpensive, and it is encroaching on the demand of international telephony, but it restricts the amount of information transmission and speed of the public network Internet. There was a complaint from the user because of the sound quality issue by

In addition, the mVoIP voice call by the international data roaming service is much more expensive than the general voice international roaming call, mainly in the free Wi-Fi (Wi-Fi) area was inconvenient.

In addition, by leasing the Internet exclusive line provided by the main telecommunication service provider, it is possible to implement low-cost international calling by VoIP (Voice over Internet Protocol), but it does not have a switchboard in a foreign country or can be connected locally. If the phone number can not be operated, it was inconvenient to use because only domestic calls, that is, only incoming calls in the country.

In addition, even in the shaded areas where mobile communication phones are not available due to insufficient local mobile communication infrastructure (Infra), even if international roaming service is available, there are many cases in which inconvenience of communication is lost due to inability to make calls.

On the other hand, the USIM (Universal Subscriber Identity Module) purchased in a local country between foreign travel and overseas business trips enables relatively inexpensive international calls and calls between local subscribers, but the changed phone number is not known to other people in Korea. There was no way to call before giving me the number.

In addition, people who work for a company or a group are uncomfortable because there is no way to make an international call through a cheap international leased line owned by the company or a group by using a landline telephone or a mobile communication terminal outside the office. It is true.

That is, the conventional international roaming system is technically different from the roaming (Roaming) between systems or networks (Network), or can be set by the operator, but there is an inconvenience in using.

On the other hand, the conventional international roaming service is convenient because it is automatic roaming, but many people evade because the international roaming fee is determined to be excessive, and many users are uncomfortable because they cannot reach the landline telephone abroad.
