Embodiment Construction

[0049] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050]The present invention is mainly applied to telecom smart cards that support Java functions and Native functions at the same time. Telecom Java applications can support preferred roaming, one card with multiple numbers, S@T, etc., as well as downloadable Java Toolkit Applet, and all aspects meet the standards of Java USIM . Telecom Native applications can support various applications, especially applications with high time requirements, such as China Unicom OTA, WIB1.3, etc.

[0051] refer to figure 1 , showing a flow chart of an embodiment of a method for integrating multiple telecommunication applications on a smart card according to the present invention, including:

Abstract

The invention provides a smart card and a method for integrating multiple telecom applications on the same. The method comprises the following steps: when receiving application protocol data unit (APDU) instructions, judging whether the APDU instructions are the instructions special for telecom applications; if so, classifying the instructions special for telecom applications; if not, executing the instructions; and analyzing the current events in the instructions and triggering and executing various types of telecom applications corresponding to the current events according to an event registry. By adopting the smart card and the method, the advantages of both the Native card and the Java card can be considered, thus ensuring the executing speed of the smart card and simultaneously realizing addition and deletion of applications.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method for integrating multiple telecommunication applications on a smart card and the smart card thereof. Background technique [0002] In the existing smart card field, according to the type of chip operating system (COS, Chip Operating System), it can be divided into Native cards and Java cards. [0003] The advantages of Native cards lie in speed and execution efficiency. Since the business application of the Native card is compiled and executed together with the underlying COS, the execution time is minimized, so the Native card has the advantages of fast speed and high execution efficiency. Some time-limited applications, such as data transmission and secure computing, can use programs in the form of Native code. [0004] However, Native cards do not have platform versatility and API interfaces for secondary development. This is because the Native card is a smart c...
