Problems solved by technology

However, since the SIM card follows the ISO 7816 protocol and the memory card follows the SD protocol, it becomes a new problem to solve the compatibility and intercommunication between the two protocols. In addition, when a new data transmission protocol is required, the existing technology cannot be well Extend the multi-protocol

Abstract

The invention relates to the technical field of mobile communication, and relates to a device and method of dynamically allocating protocol interfaces. The device comprises a card base, eight pins C1to C8 arranged on the card base, a micro control unit MCU, a nonvolatile memory, an ISO 7816 protocol interface module, a second protocol interface module and a pin configuration module. An ISO 7816 protocol and a second protocol are arranged in the micro control unit MCU, corresponding pin configuration can be carried out through the pin configuration module, and therefore switching from the ISO7816 protocol to the second protocol is achieved. According to the invention, high-capacity high-speed data transmission in the SIM card mode is realized, and good expansibility is achieved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a device and method for dynamically allocating protocol interfaces. Background technique [0002] The traditional mobile phone SIM card follows the smart card industry standard ISO7816, and its storage capacity is generally divided into 8KB, 16KB, 32KB, 64KB, 128KB and 512KB versions. The maximum capacity of the high-standard SIM card for NFC business can only reach megabytes. This kind of storage capacity cannot well support the business development of telecom operators and the application needs of end customers. In order to expand the storage space of mobile phones, users need to purchase additional expansion cards other than SIM cards (such as Micro-SD cards, also known as TF cards. ) and installed on the user's device. With the upgrading of user equipment (such as mobile phones) functions, more components need to be arranged in the equipment, so manufacturers tr...
