Embodiment Construction

[0031] The invention provides a PHS mobile phone compatible method for reading SIM card and UIM card phonebooks, figure 1 It is the PHS mobile phone start-up flow chart of applying this method, wherein: PIM, SIM, UIM card all have identical physical characteristics, electrical characteristic and transmission agreement, all accord with the ISO / IEC 7816-4 standard of relevant IC card, these are all PHS The mobile phone can recognize the basis of SIM or UIM card compatible. Therefore the existing PHS mobile phone has fully satisfied the function of being able to read the SIM card and the UIM card from the hardware, and does not need to be modified.

[0032] This method is to identify the inserted card as a SIM or UIM card through the underlying driver and the PIM protocol layer, and then report it to the MMI layer. After receiving the signal that the card is a SIM or UIM card, the MMI will only open the phonebook-related functions, and close all other functions. , so that the PH...

Abstract

The invention relates to a method for a mobile phone to read and write data from a smart card, in particular to a method for a PHS mobile phone compatible with reading a SIM card and a UIM card phone book. After the card is not a PIM card, it is judged whether the inserted card is a SIM card or a UIM card, and then only the user is allowed to perform read and write operations related to the SIM / UIM card phone book according to the judgment. Through the method of the invention, a SIM card or a UIM card can be inserted into the PHS mobile phone, and the data of the phone book of the SIM card or the UIM card can be read or written.

Description

technical field [0001] The present invention relates to a kind of method that mobile phone reads and writes data from smart card, relate in particular to a kind of PHS (Personal Handset System, personal hand-held telephone system) mobile phone compatible reading SIM (Subscriber Identification Module, subscriber identification module) card and The method of UIM (UserIdentify Module, user identification module) card phone book. Background technique [0002] Now the mobile phone has become an indispensable communication tool for people. At present, there are three kinds of mobile phone networks such as GSM, CDMA and PHS in China. Mobile phone users often come into contact with SIM cards in GSM mobile communications, UIM cards in CDMA mobile communications and PIM cards in PHS mobile communications. These three cards are all smart cards, and their technical characteristics are very similar, and they are all responsible for storing core content such as user-related identity info...
