Intelligent terminal and method for realizing dynamic virtual USIM card

Abstract

The invention discloses an intelligent terminal and method for realizing a dynamic virtual USIM card. The intelligent terminal comprises an AP side processing unit, an ISO7816 interface module, a BP side processing unit and an authentication channel module, wherein the AP side processing unit constructs a dynamic virtual USIM card, and carries out information exchange with a remote server through the authentication channel module; the BP side processing unit generates the APDU command data, and implements read and write operation on the virtual USIM card through the ISO7816 interface module; the ISO7816 interface module is respectively connected with the AP side processing unit and the BP side processing unit, responds to a start initialization process initiated by the BP side processing unit, and initializes the virtual USIM card; and the authentication channel module is connected with an operator network, and establishes a data transmission channel for the information exchange between the intelligent terminal and the remote server. According to the intelligent terminal and method disclosed by the invention, the dynamic virtual USIM card can be implemented on the intelligent terminal without providing the authentication key K values through the authentication of operators and without relying on the specific modem implementation frameworks.

Description

technical field [0001] The invention relates to the technical field of virtual USIM cards, in particular to an intelligent terminal and a method for realizing a dynamic virtual USIM card. Background technique [0002] Virtual USIM card technology plays an important role in saving roaming charges for users and providing exclusive and customized package services. For example, in the soft SIM implementation scheme, before the soft USIM card is used, the authentication key K value and the necessary file information of the USIM such as IMSI, ICCID, DIR, and ACC must be written. This requires the authentication key K value information of the network operator authorization card, and the specific implementation depends on the implementation framework of the modem platform of different schemes. Due to the resource authorization restrictions of different operators and the threshold of the modem platform as mentioned above, it is very difficult to promote and use it on a large scale i...
