Embodiment Construction

[0058] This embodiment takes an intelligent terminal with a chip of a SIM card interface controller (ISO7816) as an example, but the chip does not have an integrated SIM card controller interface, but an intelligent terminal with a SIM card interface on the main board can also implement the present invention. The hardware principle of the SIM card interface formed by connecting the SIM card interface controller with the SIM card and an external power supply is as follows: figure 1 shown.

[0059] In this embodiment, the chip is internally integrated with a SIM card interface controller (SIM), which can store the data sent by the MCU (microprocessing controller) through the bus in the sending buffer, and put it outside in a signal form conforming to the ISO7816 standard. Port, while receiving the data returned by the SIM card and storing it in the internal buffer. The chip is based on the ISO7816 protocol standard and provides SIM card interface standard signals. Its SIMCK pin...

Abstract

This invention discloses a method for piloting the SIM card phone number book into intelligent terminal. After a user at the intelligent terminal inputs the instruction of fetching SIM card phone book, the terminal initializes the SIM card interface controller and interrupts it. If the correct reset response of SIM card is received in the reset response waiting time, then it orderly sends selected phone book catalog file, data file for selecting phone books, fetching said data file head and fetching operation of the book to SIM card, any time after sending the instruction, if the generated interrupted times and received bytes are correct in the response waiting time, the operation is successful and next step is taken. The phone call recording is kept in the memory to finish the guide-in process. Local management is done to the intelligent terminal.

Description

technical field [0001] The invention relates to a fixed network terminal, in particular to a method and a corresponding device for importing a SIM (Subscriber Identity Module) card phonebook into an intelligent terminal. Background technique [0002] my country's current fixed telephone network construction is very complete, and it is the largest and most advanced fixed telephone communication network in the world. However, most of the fixed network terminals in our country are analog phones at present. Their main disadvantage is that they can only provide analog voice services, and they do not have the ability to carry complex digital services, nor can they provide the flexible phone book function like wireless terminals. Based on powerful data storage and processing capabilities and various data transmission methods, fixed-line intelligent terminals have the ability to carry complex digital services, and can provide users with flexible value-added services, so they are lov...
