Method and system for realizing long-distance communication by using mobile SIM gateway

Abstract

The invention relates to a method and system for realizing long-distance communication by using a mobile SIM gateway. With a mobile SIM gateway and a voice gateway, SIM card authentication data are transmitted to a local base station operator authentication system or mobile base station authentication remotely by an internet network based on SIM gateway access, so that an SIM card is registered to the local base station remotely; and then a local communication service with continuous communication is realized by an APP or other terminals. Therefore, an objective of roaming flow and telephone charge saving is achieved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a system for realizing long-distance communication by using a mobile SIM gateway, a data exchange processor, a local signal receiving and forwarding device, and a terminal device. Background technique [0002] With the development of communication technology, mobile phones have become an essential communication tool for everyone, especially smart phones are not only for calls and text messages, but also for certain functions of computers, such as video, wired or wireless Internet access, downloading applications and Operation, etc., play an increasingly important role in people's daily life. [0003] With the globalization of human development, due to business trips, tourism, etc., people often live in different places, which will cause mobile phone roaming, resulting in high domestic and international roaming charges, especially international roami...

Problems solved by technology

[0004] In order to achieve the purpose of saving calls (fees), there are many kinds of call saving routers or dial-up methods developed on the market, but because the original subscriber identification card (hereinafter referred to as SIM card) at the local end cannot be directly used at the remote end, this Such call-saving devices or methods usually need to change the mobile phone number or carry a specific communication device, which cannot take into account the convenience of using a mobile phone to dial and receive, so it is quite limited in use. The current common VoIP (VoIP) For example, it uses the voice transmission technology between the Internet to carry out calls between two places, and its advantage is that it can take advantage of the characteristics of the Internet's universality, so it is generally free to call each other within the network, even through local If you make a call from the transfer host at the remote or remote end, you only need to charge the fee from the local host to the local mobile phone or local call, so the cost is much lower than the international roaming of mobile phones

But its disadvantage is that general users do not have a specific number, so effective two-way communication cannot be formed. Even if a specific user uses a dedicated number, it still needs to change the number, causing inconvenience for local personnel when dialing the user's phone; Use a dedicated phone to make wireless dial-up at the remote end, and the general Internet phone is only connected through the Internet. If you do not use a mobile phone dedicated to the Internet phone, the coverage of the current wireless network base station is far lower than Mobile phone base station, so the call effect of the existing Internet phone is quite limited; in addition, it can still be used effectively for receiving incoming calls. When it wants to make a call back to the local end at the remote end, it needs to purchase additional points, and The convenience of international roaming is affected by the transfer of calls through Internet phone operators

[0005] In other words, when performing international roaming between two places, no matter whether it is international roaming of ordinary mobile phones or international roaming of Internet phones, it cannot provide the effect of saving call charges and the convenience of international roaming at the same time. Therefore, it is necessary to break these traditional call systems The restrictions caused by the mobile phone can effectively play the convenience that the mobile phone brings to people's use

[0006] Currently more advanced technology such as CN 102056350 patent solves the above problems, but its SIM card cannot be moved and carried around, which brings inconvenience to users
