Java Reporting Library-Jasper Reports From a technical pe .net vs 2010 Data Matrix 2d barcode rspective, there are two kinds of SIM applications: ones that are translated into the hardware instructions of the SIM microprocessor and ones that are translated into byte codes that are interpreted by an interpreter program installed on the SIM. Interpreted applications can be loaded onto and deleted from the SIM more easily than native code applications, but they run up to an order of magnitude slower than native code applications, depending on how much of the application is done by underlying "system code," which is invoked from the interpreted application.

Whether it is translated into microprocessor instructions or interpreted byte codes, an application is written in a programming language against an API. The generic programming API for applications on the Card Application Toolkit is codified in ETSI TS 102.240 "UICC Application Programming Interface (API).

" Language-specific bindings of this generic API have been produced for a number of procedural programming languages, including Visual Basic, C, Java, and Modula. Recently, however, what may ultimately be the winning programming paradigm for creating and deploying SIM-based mobile applications, has emerged. It is called the USAT Interpreter.

Rather than supporting procedural programming languages such as Visual Basic or Java, the USAT Interpreter takes a cue from the success of the. World Wide Web and focuses on markup languages that have been designed specifically for mobile applications such as HDML, cHTML, WML, and XHTML. A USAT Interpreter application is a series of pages that are sent to the mobile phone in SMS messages. The USAT Interpreter interprets each page just like your desktop browser interprets HTLM pages it retrieves from the Web.

(This is why the USAT Interpreter is sometimes called a SIM microbrowser.) After the USAT Interpreter has processed a page, the page is thrown away and another page of the application is retrieved from the network. The USAT Interpreter approach to mobile applications has a number of very attractive characteristics from the point of view of the network operators.

It may also more closely model the intrinsic nature of mobile applications than a procedural language program. There are three things that make USAT Interpreter applications an attractive alternative to procedural language applications to a network operator: The administration costs of USAT Interpreter programs are much lower than those of procedural language programs. The USAT Interpreter"s "fire and forget" model of computation means that applications don"t have to be installed on the SIM and linked into the SIM Toolkit framework.

Loading and installing SIM Application Toolkit programs understandably involves a lot of fancy cryptography and procedural safeguards because live code is being added to the SIM. The cost of these administrative procedures is avoided with USAT Interpreter programs because an interpreter page is just held in a temporary buffer while it is being processed. Of course, if you turn off the phone, the pages go away.

For a network operator, this is a feature, not a bug. A USAT Interpreter program doesn"t take up any of the precious EEPROM space on the SIM because it isn"t installed permanently. This means that there is plenty of room for telephony data such as phonebooks, dialing policies, and routing and roaming data.

It also means that the subscriber can change his or her mind about what mobile applications he or she wants to use without contacting the operator"s SIM administration system. This is much more convenient for the subscriber and much more efficient for the operator. A USAT Interpreter program has regularization and control of the user interface.

Customer care centers are expensive to operate. They are a necessary part of doing business, but each call to a customer care center is money down the tubes. If a subscriber has problems with a mobile application, they aren"t going to call the provider of the program.

They are going to call the operator"s customer care center.. It is hard to tell Data Matrix for .NET by analyzing a procedural language program what the user experience with the program will be. It"s even harder to build a procedural language program that adapts itself to the human interface style policies of different operators.

Exactly the opposite is true of markup language programs. A markup language page in a sense is the human interface to the page. And each operator can publish markup language style templates that describe and enforce the user experience with that particular operator"s applications.

Applications just add data to these templates. The human interface stays consistent, just the application context and task change. The requirements of the network operators are exactly why.

markup languages we re invented. The operator controls the presentation and the application provider controls the content. Table 8.

10 lists the standards documents that define the USAT Interpreter. Full-text markup language pages are converted to USAT Interpreter byte codes for efficient transmission and execution but this is purely a behind-the-scenes process as far as the application provider is concerned. All the application provider has to do is put the pages for his or her application on an Internet server.

The network operator takes it from there..
