Smart card, system and method for realizing deployment customized service

Abstract

The invention discloses a smart card and a system and process for realizing the deployment and customization service. At least one customization service file is preset in the smart card, and the mobile terminal firstly emits an operating command packaged with data to the customization service file. The smart card performs operations to the corresponding customization file after receiving the operating command, writes the obtained customization traffic data into the data exchange file, and return back a command response / execution status. The mobile terminal emits a data reading exchange file command based upon the returned command response / execution status. The smart card returns the data exchange file to the mobile terminal after receiving the data reading exchange file command, and then the mobile terminal receives, analyzes and displays the customization service data in the data exchange file. The invention can operate the customization file flexibly by the smart card and can combine with the mobile terminal to realize the preset and display of the customization service of mobile operators.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for presetting and displaying mobile communication operator brand information and value-added services based on a smart card in a mobile terminal. Background technique [0002] With the combination of wireless communication technology and Internet technology, more and more Internet value-added services have been introduced into the field of wireless communication, making wireless value-added services popularized and promoted rapidly, and bringing unlimited business opportunities. Mobile communication operators increasingly realize that only by providing users with better quality and more attractive data services can they maintain their high ARPU growth. [0003] However, unlike Internet value-added services, which are carried out based on PCs, wireless value-added services are limited by terminals (usually used on mobile phones or PDAs) and network conditions, which to a certai...

AI Technical Summary

Problems solved by technology

[0006]However, the disadvantage of this method is that, first of all, there are so many terminal models and software architectures in the market that it is impossible to provide a unified service bearing platform

The deployment and development of services for each model will undoubtedly greatly increase the cost of operators' business operations

At the same time, operators' initiative and control over business promotion are also greatly restricted

In addition, with this method, it is difficult for the business to modify, upgrade and update in subsequent use

Since the software on the terminal has been written into the ROM of the mobile phone before leaving the factory, if it needs to be updated later, it must be performed by the mobile phone manufacturer. This will undoubtedly increase the difficulty and cost of mobile operators in upgrading customized services in existing user terminals. Unable to bring continuous service and profit in the later period

[0007] Although pre-installed applications based on smart cards can provide operators with a unified data service platform, they are limited by many technical conditions including the processing capabilities, communication means, and capacity of smart cards. As a result, applications developed based on smart cards can only provide functions. Simple, single-mode services, typically SIM Application Toolkit (SAT, SIM Application Toolkit, or STK for short), cannot accommodate more media-based and network-based application deployment requirements
