Dynamic Domain Selector for Mobile Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices are limited in their ability to dynamically switch between circuit switched and packet switched domains for communication, leading to reliability and cost trade-offs, where circuit switched calls offer better quality but are more expensive, while packet switched calls are less reliable and cheaper.
Innovation Solution
A mobile device with a domain selector that allows users to dynamically choose between circuit switched and packet switched domains on a per-call basis, using a technology selector to automatically select appropriate networks and protocols based on user preferences and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If circuit switched mode is used for communication, then communication quality and reliability are improved, but communication cost increases
Solution Approach 1:
The patent implements dynamic domain selection that allows the mobile device to switch between circuit switched and packet switched domains based on user preferences, call characteristics, and network conditions. This dynamic approach resolves the contradiction by enabling the system to adaptively choose the most appropriate domain for each specific communication scenario, rather than being fixed in one domain.
Solution Approach 2:
The patent changes the operational parameter of the communication domain (circuit switched vs. packet switched) based on varying conditions including user preferences, call type, duration, and network availability. This parameter change allows optimization of both reliability and cost by selecting the appropriate domain for each communication instance.
2Loss of energy
If packet switched mode is used for communication, then communication cost is reduced, but communication reliability deteriorates
Solution Approach 1:
The dynamic domain selection mechanism enables the system to switch from packet switched to circuit switched domain when higher reliability is needed, while still allowing packet switched mode for cost-sensitive communications when reliability requirements are lower. This resolves the contradiction by making reliability adaptable to specific communication needs.
Solution Approach 2:
The patent varies the communication domain parameter based on call characteristics, user preferences, and network conditions, allowing the system to achieve cost efficiency through packet switching while maintaining reliability through circuit switching when necessary.
3Ease of operation
If default domain is used for all calls, then device operation is simplified, but communication optimization is limited
Solution Approach 1:
The patent implements a multi-functional domain selection system that can operate in multiple modes: default domain selection for simplicity, user-directed selection for optimization, and automatic selection based on call characteristics. This universal approach resolves the contradiction by accommodating different operational needs within a single system.
Solution Approach 2:
The system provides self-service through automatic domain selection based on pre-configured user preferences and call characteristics, eliminating the need for manual user input while still achieving optimized communication. This resolves the contradiction by providing both simplicity and optimization simultaneously.
