USSD Client-Server System for Mobile Terminal Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current client-server systems for mobile telecommunications struggle with providing real-time, interactive, and user-friendly services due to limitations in resource constraints of mobile terminals and networks, leading to suboptimal response times and ergonomics, especially when using existing protocols like WAP or HTTP.
Innovation Solution
A digital telecommunications client-server system utilizing a USSD protocol with a navigation module, presentation module, and decoder interpreter module embedded in mobile terminals, allowing for efficient data interpretation and display, and enabling seamless communication with a network server for interactive services without requiring extensive modifications to terminals or networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing protocols like WAP or HTTP are used for mobile telecommunications, then compatibility with standard networks is maintained, but response times are suboptimal and resource consumption is high
Solution Approach 1:
The patent introduces USSD protocol which fundamentally changes the communication parameters from request-response model to event-driven model with immediate network response, achieving sub-second response times while reducing terminal resource consumption through efficient message handling
2Adaptability or versatility
If more services and features are added to mobile terminals, then functionality and versatility increase, but device complexity and resource constraints are exacerbated
Solution Approach 1:
The patent introduces a service layer intermediary that manages multiple services through a unified USSD interface, allowing diverse functionalities (banking, information, entertainment) to be accessed without increasing terminal complexity, as the service management complexity is shifted to the network side
3Ease of operation
If client applications are embedded on mobile terminals with limited resources, then service functionality is provided, but ergonomics and user interface quality deteriorate
Solution Approach 1:
The patent inverts the traditional client-server model by making the network side the intelligent initiator that pushes services to terminals, rather than terminals requesting services. This inversion allows rich service functionality to be delivered without burdening terminal resources, maintaining excellent ergonomics
4Speed
If real-time services are implemented in mobile networks, then service responsiveness improves, but network infrastructure complexity and cost increase
Solution Approach 1:
The patent creates a universal USSD service framework that can deliver multiple real-time services (banking transactions, information queries, entertainment) through a single protocol and interface, achieving service responsiveness without proportionally increasing network infrastructure complexity
Data Source
AI summary
A digital telecommunications client-server system where a network server communicates by a protocol with a digital application located on a mobile terminal. The digital application includes a navigation module, a presentation module, a decoder interpreter module and a transport module. The digital application interprets data received from a network server located in a mobile core telecommunications network and displays interpreted data on a screen of the mobile terminal, with the interpreted data relating to a service or application. The digital application interprets a request of a user entered into the mobile terminal in response to the interpreted data displayed on the screen of the mobile terminal, and sends from the mobile terminal data interpreted from the user's request to the telecommunications network.
