Embodiment Construction

[0027] First, explain the working principle of the present invention, such as figure 1 As shown, specifically including:

[0028] 101) The mobile terminal 1 obtains the calling number and uses the APDU command to transfer the calling number and the corresponding query instruction;

[0029] 102) The smart card 2 obtains the calling number and the corresponding query instruction to query the relevant data of the large-capacity phone book;

[0030] 103) Smart card 2 returns relevant data;

[0031] 104) The mobile terminal 1 displays relevant data.

[0032] The second step is to briefly explain the basis of the invention (the basic principle of data transmission):

[0033] The mobile communication terminal and the smart card adopt the ISO / IEC 7816-4 and / or GSM 11.11 protocol for communication. The GSM 11.11 protocol is the specific application of the ISO / IEC 7816 protocol in the GSM system.

[0034] ISO / IEC 7816-4 is a master-slave structure, command response protocol. APDU is divide...

Abstract

The invention relates to a caller ID displaying method for a large capacity phonebook in a smart card. The caller ID displaying method comprises the following steps: when incoming call comes, a mobile terminal (1) acquires a calling number and transfers the calling number and an inquiry instruction to a smart card (2); the smart card identifies and inquires about the large capacity phonebook of the smart card according to the calling number and the inquiry instruction, and returns the results of correct execution or wrong execution; the mobile terminal directly displays the calling number according to the results of the wrong execution or acquires inquiry results according to the results of the correct execution and displays the inquiry results; the inquiry results displayed include the calling number and information matched with the calling number and displayed by the mobile terminal or only the calling number displayed. The method can inquiry about and display more than 254 pieces of record information in the large capacity phonebook in the smart card on a real-time basis, thereby improving the availability of the record information and avoiding modifying terminal hardwares.

Description

Technical field [0001] The invention relates to a mobile terminal and a smart card application, in particular to a method for displaying the caller ID of a large-capacity smart card. Background technique [0002] With the development of smart card technology, the capacity of smart cards has been greatly improved, reaching M-level or even G-level. In this way, the phone entries stored in the smart card increase accordingly. Traditionally, when a phone call occurs, the mobile communication terminal can read and display the information (such as name) corresponding to the phone number from the 254 phone records corresponding to the smart card 6F3A file. However, due to the limitation of ISO / IEC 7816-4 and GSM 11.11 protocol, when the incoming call number exceeds the 254 data space, the mobile communication terminal cannot use the traditional APDU command to access the remaining phone entries in the large-capacity phone book. Unable to complete the query and display of information suc...
