Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite communication is used to provide global network mobility, then network connectivity is improved, but capital and operational costs increase significantly
Solution Approach 1:
The patent segments the communication system into multiple components: terrestrial broadband base stations for high-speed connectivity in coverage areas, satellite communication as backup for remote areas, and a gateway that manages the transition between them. This segmentation allows the system to use cost-effective terrestrial infrastructure whenever possible while relying on expensive satellite resources only when necessary.
Solution Approach 2:
The patent changes the operational parameters by implementing a hybrid communication approach that dynamically adjusts between terrestrial broadband and satellite communication based on signal availability, location, and network conditions. This parameter change enables cost optimization by selecting the most economical communication path for each scenario.
2Area of stationary object
If satellite communication is used for global mobility, then network coverage is improved, but security concerns increase due to third-party providers
Solution Approach 1:
The patent introduces a gateway as an intermediary component that sits between the satellite communication infrastructure and the enterprise network. This gateway implements security functions including authentication, encryption, and protocol translation, allowing the enterprise to maintain control over security policies while still accessing satellite coverage when needed.
Solution Approach 2:
The gateway device performs multiple functions: it manages terrestrial broadband connections, handles satellite communication protocols, implements security policies, and dynamically routes traffic between different communication modes. This multi-functionality consolidates security management in a single controllable component rather than relying solely on third-party satellite providers.
3Adaptability or versatility
If satellite communication is used for network connectivity, then global mobility is achieved, but bandwidth scalability is limited since upgrades must be requested from the satellite provider
Solution Approach 1:
The patent implements a dynamic communication system that can adapt bandwidth allocation in real-time based on network conditions and user requirements. The terrestrial broadband portion offers scalable bandwidth upgrades through standard telecom processes, while the satellite portion provides dynamic path selection. The gateway dynamically adjusts routing decisions to optimize bandwidth utilization across both communication modes.
Solution Approach 2:
The patent merges terrestrial broadband and satellite communication into a unified hybrid system. This combination allows the enterprise to leverage the high bandwidth scalability of terrestrial infrastructure while maintaining the global mobility capabilities of satellite communication. Bandwidth can be scaled independently in each mode according to specific operational needs.
4Device complexity
If early IP protocols are used assuming fixed locations, then network protocol simplicity is maintained, but seamless connectivity for moving users cannot be achieved
Solution Approach 1:
The gateway acts as an intermediary that handles the complexity of mobility management while presenting a simple interface to both the core network and remote devices. It implements IP address management, session continuity, and protocol translation functions that enable seamless connectivity for moving users without requiring changes to standard IP protocols in the end devices.

AI summary
A method for extending connectivity from a core network to remote mobile networks includes: installing a security gateway between the core network and wireless broadband base stations located at a periphery of the core network; creating a virtual layer 2 (data link) overlay network interconnecting the broadband base stations; activating a local layer 3 (network) protocol between the security gateway and the core network; activating a sensor protocol between the security gateway and each remote mobile network, the sensor protocol being configured to use broadband communication through the broadband base stations when at least one broadband base station is in range of the remote mobile network, and otherwise use satellite communication; and providing each remote mobile network with a remote layer 3 protocol that uses the broadband communication until disconnected from the broadband base stations, and then uses the satellite communication until reconnected to one of the broadband base stations.
