Embodiment Construction

[0023] refer to figure 1 , a structural schematic diagram of an existing embedded SIM card is given, and the embedded SIM card includes a hardware part and a software part. The hardware part of the embedded SIM card includes a processor, an encryption and decryption unit, etc., and usually exists in the form of a chip. The software part of the embedded SIM card runs on the hardware of the embedded SIM card, that is, when the hardware of the embedded SIM card is powered on, the software part of the embedded SIM card runs on it.

[0024] The software of the embedded SIM card includes an embedded SIM card operating system and a data security domain. The embedded SIM card operating system contains the most basic platform features and supports the features defined in GPCS. The data security domain includes eUICC Certificate Authority Security Domain (eCASD), certificate issuer root security domain configuration (Issuer Security Domain Root, ISD-R) and configuration file data secu...

Abstract

A mobile terminal, an embedded SIM card and an access method and device thereof, wherein the embedded SIM card access method includes: receiving an access instruction for accessing the embedded SIM card; obtaining the embedded SIM card corresponding to the access instruction Identification; in a preset virtual machine running a plurality of operating systems corresponding to embedded SIM cards, select an operation corresponding to the identification of the embedded SIM card according to the identification of the embedded SIM card corresponding to the access instruction system and access. The above scheme can realize simultaneous access of multiple numbers.

Description

technical field [0001] The invention relates to the field of intelligent terminals, in particular to a mobile terminal, an embedded SIM card and an access method and device thereof. Background technique [0002] A subscriber identity module (Subscriber Identity Module, SIM) card is also called a subscriber identity card or a smart card. Existing mobile terminals, such as smart phones, need to be installed with SIM cards in order to provide security services such as mobile network access authentication and user identification. In the SIM card, private information of the mobile terminal customer is stored, for example, content such as the user's phone book. [0003] In order to further expand the application field of smart cards, reduce the volume of mobile terminals, adapt to more complex and harsh external environments, and maintain a longer service life and data storage cycle, embedded SIM cards have emerged as the times require. Embedded SIM card (also known as eUICC car...
