Abstract: A terminal includes a security subsystem, a baseband processor, and a first bidirectional bus coupled between the security subsystem and the baseband processor. The security subsystem is configured to manage at least one of data related to a user identity or data related to network security in wireless communication, and exchange the data with the baseband processor by using the first bidirectional bus. The baseband processor is configured to exchange the data with the security subsystem by using the first bidirectional bus, and implement wireless communication by using the data. The security subsystem and the baseband processor are in the same hierarchy. The security subsystem may proactively perform data transmission by using the first bidirectional bus.

Abstract: A processor chip including a memory controller, application processor and a communication processor, where the memory controller is configured to define an area of memory as secure memory, and allow only an access request with a security attribute to access the secure memory. The application processor is configured to invoke a secure application in a trusted execution environment, and write an instruction request for a secure element into the secure memory using the secure application. The communication processor is configured to read the instruction request from the secure memory in the trusted execution environment, and send the instruction request to the secure element. The application processor and the communication processor need to be in the trusted execution environment when accessing the secure memory, and access the secure memory only using the secure application.

Abstract: A mobile terminal, a maintenance server, a method and an apparatus for maintaining a virtual subscriber identity module (SIM) card, where the method includes checking that a physical SIM card is inserted into a physical SIM card slot, switching a SIM card in a working state from the virtual SIM card to the physical SIM card using a SIM card switching switch, accessing a carrier network using the physical SIM card, receiving maintenance data sent by a maintenance server to the physical SIM card, and maintaining the virtual SIM card according to the maintenance data. Hence, after data of a virtual SIM card is damaged, the virtual SIM card can still be maintained without returning the virtual SIM card to a manufacturer for repair.
