Mobile terminal supporting virtual SIM card and its user identity authentication method

Abstract

The invention provides a mobile terminal supporting a virtual SIM card and the user identity authentication method thereof. Programs and functions realized by the prior real SIM card are realized by a mobile terminal; account information is written into the mobile terminal through a mobile network by means of a password card as well as the local retrofit and the program updating to mobile network equipment; and an account is not activated by selling the real SIM card. The invention realizes that the mobile terminal supporting a virtual SIM card can simply use local mobile networks to communicate by purchasing one password card in other countries or across provinces or municipalities, thereby reducing roaming fees, reducing the consumption of the SIM card, reducing the waste of the resource, and reducing customer complaints brought by the incompatibility of the mobile terminal and the SIM card. The invention provides a convenient, flexible, safe mode of using mobile phones in different places. The mobile terminal supporting the virtual SIM card is advantageous to the realization of new functions of the mobile terminal and the decrease of the design cost, and ensures that the popularization of the new functions gets easier.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal which adopts a virtual SIM card to realize mobile communication and a user identity authentication method thereof. Background technique [0002] Since Bell, an American inventor, invented telephone communication, communication technology has experienced rapid development and popularization from wired telephones to mobile telephones. In particular, the popularization of mobile phones has greatly improved the convenience and anytime, anywhere of people's communication, making mobile phones full of infinite vitality in the development of today's information industry. The development of the mobile phone itself has also experienced the change from an integrated mobile phone terminal to a machine-card separated mobile phone terminal. The so-called integrated mobile phone terminal means that the mobile phone terminal's online authentication account information and ...

AI Technical Summary

Problems solved by technology

[0009] The present invention hopes to propose a new mobile terminal implementation scheme, and at least partly solve the above-mentioned problems through the transformation of the existing network, including how to realize the advantages of the convenience of separating the machine and the card, and remove the independent SIM card and its interface. The security issues brought about; how to reduce the waste of resources caused by changing account information; how to effectively reduce the problem of high roaming across countries and regions; how to solve the shortage of SIM card resources but want to run complex applications but cannot use mobile terminals The problem of signal processing resources; how to improve the utilization efficiency of number resources
