Problems solved by technology

[0004] When the terminal supports a virtual SIM card, in some cases, it will cause the management of the virtual SIM card by the modem processor and the application processor to be out of sync.
For example, when abnormal conditions such as abnormal communication and system instability occur in the terminal, after RIL / QMI / AT is reconnected, or the application processor restarts, etc., the management of the virtual SIM card by the application processor and the modem processor will be out of sync. The problem
[0005] And there is no good solution in the prior art

Abstract

The invention discloses a virtual SIM card synchronous management method and a terminal. The method comprises the steps of disabling a virtual SIM card by a modulator-demodulator processor and sending a message to a virtual card processing module when a first preset condition is met; initiating a virtual SIM card activation request by the virtual card processing module; and comparing an ICCID (Integrated Circuit Card Identity) of the current card with an ICCID in a preset storage region by an application processor, and activating and enabling the virtual SIM card when the ICCID of the current card is the same as the ICCID in the preset storage region. The method and the terminal have the beneficial effects that the virtual SIM card is disabled through the modulator-demodulator processor, and the virtual SIM card is reactivated, so that the modulator-demodulator processor and the application processor perform synchronous management on the virtual SIM card; and in addition, when the application processor is restarted, the virtual SIM card can be inserted again, so that the problem in synchronization between the modulator-demodulator processor and the application processor is solved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a virtual SIM card synchronization management method and terminal. Background technique [0002] A virtual SIM (VSIM) card refers to a technology that simulates a physical card and does not require a built-in physical SIM card. The terminal can download card data from the relevant server by downloading, which provides convenience for users. [0003] In order to better process the signal, the existing terminal generally includes a modem processor and an application processor. The modem processor is used to complete protocol processing and to modulate and demodulate the communication data sent and received to achieve Functions such as communication with external communication equipment. The application processor is used to process complex logic operations and perform task allocation, provide interactive interfaces for users, and run operating systems. [0004] Whe...
