Problems solved by technology

It takes hundreds of seconds to transfer an M-sized file at this rate, and it will take longer if factors such as transmission overhead and fault tolerance are considered
[0007] Fourth, the STK application development interface used by traditional SIM cards is mainly used to process text-based services, which cannot implement complex applications such as graphics and networks, and the user experience is poor; secondly, the software system of traditional smart cards does not yet have a real operating system Functionality, structurally unable to support flexible changes by application developers or even end customers
[0009] However, there is currently no mobile terminal that can fully support this new type of smart card.
The concentrated performance is in the following aspects: the existing terminal design cannot support the connection with its newly added high-speed interface, and configure and manage it; it cannot provide the new smart card with the power required for its operation; In the terminal architecture, the SIM card and USB / SD / MMC device chips are completely independent, and the communication between them and their respective hosts can be carried out separately without interfering with each other, without additional synchronization and handshake mechanisms

Abstract

The related new intelligent mobile phone with high-performance computation, grand-scale memory, and high-speed transmission comprises: a baseband processor chip, a RF module, a SDRAM, a LCD, a keyboard, and some DAC and ADC circuits, wherein a built-in 8-pin intelligent card socket accords with ISO / IEC 7816 standard and connects with C4, C6, C8 pins of socket as well as the baseband processor chip pin; a power management chip provides 3.3-5V voltage for all modules in phone, as well as the SIM card through intelligent card socket C1 pin. This invention supports GSM communication, has massive data storage and high-speed data communication, and supports new application in intelligent card.

Description

technical field [0001] The invention belongs to the technical field of mobile phones, and in particular relates to a mobile phone with a novel smart card that can support high-performance computing, super-large-capacity storage, and high-speed data transmission. Background technique [0002] Since the early 1990s, smart cards have been successfully applied to GSM terminals in Germany, and have been widely used in various mobile communication networks, such as UIM cards used in CDMA terminal equipment and USIM cards used in 3G terminal equipment Wait. The smart card (also known as the Subscriber Identity Module, SIM-Subscriber Identity Module) loaded in the mobile terminal mainly completes user identification and authentication on the GSM network, voice communication support, short message service and other various STK-based services. value-added services. [0003] However, for a long time, the SIM card circuit and software technology has been using the basic design concept...
