Description

System and corresponding method for realizing mobile communication by hosting SIM card

The present application claims priority to Chinese Patent Application No. 201510160473.2, entitled "A System for Implementing Mobile Communication by Hosting a SIM Card and Corresponding Method", which is filed on April 8, 2015. The content is incorporated herein by reference.

Technical field

The present invention relates to the field of mobile communication technologies, and in particular, to a system and a corresponding method for implementing mobile communication by hosting a SIM card.

Background technique

As we all know, in mobile communication, the SIM card plays an important role as the identity assigned by the operator to the user. The SIM card mentioned in this article, whether it is a physical SIM card or a virtual SIM card, although the form is different, but the essence is the same, the IMSI and KEY for mobile network identification and authentication are stored on the terminal. value. The wireless Modem (Communication Baseband Chip) module in the mobile terminal is responsible for communicating with the SIM card, and completes signaling interaction with the mobile network, thereby implementing basic mobile communication services such as voice and short message. The way in which the current mobile communication uses the SIM card is called the communication method in which the SIM card is coupled to the Modem.

In the prior art, the communication mode of the SIM card and the Modem coupling, in addition to the common SIM card embedded in the mobile terminal form, there are two types of SIM card hosting modes:

1) The SIM card is tightly coupled with the Modem and placed remotely: the main purpose is to implement voice and SMS on the mobile app without a SIM card. The SIM card and the Modem tightly coupled communication module (the SIM card includes both the physical SIM card and the virtual SIM card) are placed in any physical space, and can be connected to the Internet through a router such as a router, so that the module can communicate with the background server. On the mobile terminal, there is a corresponding software client (hereinafter referred to as a mobile app), and the background server can also be connected through a data channel (3G/LTE cellular data network or WiFi wireless network) provided by the mobile terminal. In this way, the mobile app can communicate with the Modem module through the background server transfer, thereby driving the Modem module to work through the mobile App, performing voice and short message services, and embodying the final voice and short message content on the mobile application.

2) Separation of SIM card from Modem: The main purpose is to realize data Internet service on mobile terminals (such as MiFi) without a real SIM card. The SIM card or SIM card pool is remotely placed and hosted in any physical location that can be connected to the Internet. On a mobile terminal (such as MiFi), insert a fake SIM card or SIM card proxy to read the information of the remote SIM card and let MiFi log in. During the network access process, when an authentication request sent by the network is encountered, it will be sent to the remote SIM card for calculation, and the result of the calculation will be returned to the network. In this way, the mobile terminal's cellular data access requirements are completed, and then the data service can be enjoyed.

Therefore, the current technology realizes that the SIM card has to deal with the Modem to realize the required mobile communication service.

In addition, the SIM card and Modem coupling technology, one SIM card corresponds to one Modem, and multiple SIM cards means that multiple Modems are required, and the communication cost is high; and the Modem work needs to cover the mobile communication signal, the coverage is weak or the coverage is not covered.
