Example Embodiment

[0019] The principle and method of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Such as figure 1 As shown, the virtual SIM card system proposed by the present invention is provided with a physical SIM card pool and a SIM card management module remotely. The physical SIM card pool stores various physical SIM cards of different operators in different countries or regions. The number of SIM cards is not limited, and can be massive, among which physical SIM cards corresponding to countries, operators, tariff packages, and network standards can be selected. The SIM card management module is located in the remote server, and manages the information of the physical SIM card in the physical SIM card pool. It will filter the corresponding physical SIM card information from the physical SIM card pool according to some allocation strategies and send it to the corresponding Mobile terminal. The allocation strategy can select t...

Abstract

The invention discloses a virtual SIM card system and a method of using a virtual SIM card by a mobile terminal. The virtual SIM card system comprises a physical SIM card pool, and an SIM card management module for managing and distributing physical SIM card information. The mobile terminal which communicates with the SIM card management module comprises a high-pass LTE chip with double communication channels and a global roaming card for reporting the current position to the SIM card management module through one communication channel; an APPS module of the high-pass LTE chip receives the information of corresponding physical SIM card through the other communication channel, obtain authentication data from the corresponding physical SIM card through the SIM card management module and then transmits the authentication data to the MPSS module of the high-pass LTE chip in an unvarnished transmission manner; and the MPSS module communicates with the base station at the currently located position to finish functions of the corresponding physical SIM card. Through a software number reading method, corresponding virtual SIM cards are provided for users without depending on hardware, and the cost is saved.

Description

technical field [0001] The present invention relates to a virtual SIM card system, and also relates to a method for using the virtual SIM card by a mobile terminal using the virtual SIM card system. Background technique [0002] Mobile phones are a necessity in people's daily work and life. Each mobile phone is equipped with a SIM card. The SIM card is also called the Subscriber Identity Module (SIM), which is mainly used to store user identification data, short message data and Smart card with phone number. The mobile phone or other mobile terminal reads the information of the physical SIM card, performs relevant authentication, and performs wireless communication under the 3GPP / 3GPP2 network after passing. [0003] In the existing technology, there are many different network operators in a country, and the network operators in each country are different. Each physical SIM card will correspond to the only operator network in one country. If you often go abroad, do business...
