Problems solved by technology

ISO7816-12 defines the IC-USB electrical interface and operation process. The transmission efficiency of ISO7816 interface 5 is low, and the access delay is large, which affects the overall performance of the terminal, such as long boot time, slow network search, etc.
ISO7816 can no longer adapt to the development trend of multi-mode terminals and the needs and performance requirements of multiple communication modules accessing the SIM card 20 at the same time

Embodiment Construction

[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] refer to figure 2 Propose an embodiment of the device 10 for SIM card information transmission of the present invention, including a USB interface 12 and a SIM management unit 11, the SIM management unit 11 reads the data of the SIM card 20 through the USB interface 12, and completes the SIM card data reading to the terminal and perform corresponding protocol processing. The SIM card data is the data of multiple SIM cards 20 or the data of multiple communication systems in a single SIM card 20 , and this article takes the data of multiple communication systems in a single SIM card 20 as an example for illustration.

[0035] refer to image 3 The device 10 for SIM card information transmission can also include an ISO7816 interface 13 and a SIM agent unit 14, and the SIM management unit 12 simultaneously reads...

Abstract

The invention discloses an SIM (subscriber identity module) data acquiring method used for a terminal comprising a plurality of communication modules. The method includes: a preset SIM information transmission device reads the SIM data through a USB (universal serial bus) interface; the SIM data refer to data of a plurality of SIMs or data of a plurality of communication systems in a single SIM; and the SIM data are provided for the corresponding communication modules. The invention further provides the corresponding device and the corresponding terminal. By the method, the device and the terminal, the SIM data are read at a high speed, and terminal performances are improved greatly.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and terminal for acquiring SIM card data. Background technique [0002] After entering the 3G era, mobile operators are faced with the long-term coexistence of multiple networks such as 2G, 3G, and subsequent LTE. Many mobile operators regard multi-network collaboration as their operational goals and optimization strategies, and propose "no card replacement, no number replacement". , No need to register” and customized multi-mode terminals for business promotion and multi-network operation. [0003] Multi-mode terminals can be divided into two types: multi-card and single-card. A multi-card multi-mode terminal uses multiple SIM cards, and each card corresponds to an independent communication system and can reside in different communication systems. The single-card multi-mode uses a SIM card to reside and complete corresponding communication functions according...
