Description

External device connection method, external device connection device, and terminal

This application claims priority to Chinese Patent Application No. 201510258883.0, filed on May 20, 2015, entitled "External Device Connection Method, External Device Connection Device, and Terminal", the entire contents of which are incorporated by reference. In this application.

Technical field

The present invention relates to the field of terminal technologies, and in particular, to an external device connection method, an external device connection device, and a terminal.

Background technique

At present, the connection scheme between a terminal (such as a mobile phone) and a peripheral device in the related art is generally that when the terminal is connected to the peripheral device, the peripheral device is directly connected with the currently running system in the terminal, and when the terminal has multiple systems with different security levels. , then multiple peripherals share the peripheral. Among them, the peripheral refers to the external device, which is used to refer to the hardware device other than the terminal host, plays the role of transmission, transfer and storage of data and information, and is an important component of the terminal. For example, the peripheral device can be a Bluetooth headset, a wired headset. , wearable devices, etc.

However, the connection of terminals and peripherals in which a plurality of systems are installed in the related art does not take into consideration the security requirements of a system with a higher security level in the terminal, if the system or peripherals currently running in the peripheral connection terminal are If the systems are shared, the security of the data in multiple systems is not guaranteed. For example, if the smart watch does not allow direct reading of data in a system with a higher security level, the data in the system with higher security level is easy. After being leaked, or the external camera is connected to the terminal, the private photos taken by the external camera are directly stored in the system with lower security level, and the private photos are easily stolen.

In addition, the user has two requirements for the performance of the terminal. The terminals in the related art cannot meet the requirements of the user. On the one hand, the user can use one system in the terminal while the peripheral device can be in another The system starts up and running. For example, the user can make a call in a system with a higher security level, or use an external camera to take a picture in another system. On the other hand, users can run different peripherals simultaneously on different systems in the terminal. For example, two people use the same terminal, one of them is used in a system with lower security level. The line earphones listen to songs, and the other person uses a Bluetooth headset to make a call in a system with a higher security level.

Therefore, how to enable different peripherals to access different systems, so that different systems can manage access peripherals of different systems, thereby avoiding data leakage of systems with higher security levels due to sharing of peripherals by multiple systems, and also It is an urgent problem to be solved by enabling multiple systems to use multiple peripherals in parallel at the same time to improve the user experience of multiple systems.

Summary of the invention
