Embodiment Construction

[0062] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0063] Before explaining the embodiments of the present application in detail, the terms and application scenarios involved in the embodiments of the present application are described.

[0064] First, the terms involved in the embodiments of the present application will be described.

[0065] Security subsystem: It is a security isolated subsystem, and its internal components are invisible to the outside world, that is, functional components outside the security subsystem can only access the security subsystem through specific interfaces. For example, the security subsystem can be a smart card (Smart card). ) (also known as integrated circuit (Integrated Circuit, IC) card, microchip card, etc.) and so on. The security subsystem can be us...

Abstract

The present application discloses a terminal and a communication method, which belong to the technical field of communication. The terminal includes: a security subsystem, a processing main system, and a first bidirectional bus coupled between the security subsystem and the processing main system; the security subsystem is used to manage data related to user identity in wireless communication and network security at least one item of related data, and exchange the data with the processing master system through the first bidirectional bus; the processing master system is used to exchange the data with the security subsystem through the first bidirectional bus, and use the data to achieve Wireless communication. In this application, the security subsystem and the main processing system are in the same position, that is, the security subsystem and the main communication system can actively transmit data to each other through the first bidirectional bus, thereby improving the flexibility of communication between the security subsystem and the main processing system. Since the transmission rate of the first bidirectional bus is relatively fast, the communication rate between the security subsystem and the processing main system can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a terminal and a communication method. Background technique [0002] With the development of communication technology, terminals such as mobile phones and tablet computers have become an indispensable part of people's daily life. The terminal usually includes a smart card and a communication processor, and the smart card stores at least one of data related to user identity and data related to network security, such as communication parameters, authentication data, etc. The device can communicate with the smart card to read data stored in the smart card. [0003] In the related art, the smart card is connected with the communication processor through a contact contact, and at this time, the smart card and the communication processor communicate according to the ISO7816 protocol. In the ISO7816 protocol, the communication processor is in the active positio...
