Embodiment Construction

[0031] The following uses the SIM application as an example to illustrate the design idea and solution of the present invention.

[0032] Analyzing the current ISO / IEC7816 (International Organization for Standardization / International Electrotechnical Commission 7816) protocol adopted between mobile terminals and smart cards shows that APDUs (Application Protocol Data Units) are divided into command APDUs and response APDUs. The host sends a command APDU to the smart card; after the smart card accepts the command APDU, it executes the command and returns a response APDU.

[0033] The format of the command APDU is as follows:

[0034] CLA INS P1 P2 Lc Data Le

[0035] The meaning of each byte is:

[0036] CLA: command category, GSM11.11 regulation, 0xA0 is used for GSM application;

[0037] INS: instruction code;

[0038] P1, P2: The parameters of the command, the meaning of P1, P2 is related to the specific command.

[0039] Lc: the length of the se...

Abstract

The invention discloses a smart card and a method to realize fixed dialing and forbidden dialing by the smart card, comprising steps of: creating a fixed dialing number file in a data storage area of the smart card and creating a fixed dialing open / close and a forbidden dialing open / close option in a development tool menu module of the smart card; then under condition of distributing and activating call control service, when the user calls actively, the smart card judges whether receives a call control instruction sent by a mobile device; after receiving the call control instruction, judging the open / close option of the fixed dialing and forbidden dialing and executing corresponding call movement according to judgment result. The invention makes the fixed dialing and forbidden dialing function be applied on the mobile device supporting development tool packet via a development tool packet technology.

Description

technical field [0001] The invention relates to the smart card (subscriber identification module) technology in the field of mobile communication, in particular to a smart card and a method thereof which utilize the tool development kit technology to realize the functions of fixed dialing and dialing prohibition. Background technique [0002] In the initial stage of the development of mobile communication technology, the main body of the business is the voice service, and most system resources (including communication channels and mobile communication equipment) are used to handle voice communication between users to meet the needs of users for mobile calls. Later, as customers put forward new requirements for mobile communications, a single voice service could no longer meet various needs of users. Users expect to be able to complete various tasks such as entertainment and office work through mobile terminals. At the same time, with the development and progress of mobile c...
