A smart RAN for wireless distributed cloud computing that communicates with Wi-Fi, LTE, and 3G networks, using a network interface unit and processing unit to dynamically choose the best network for data transmission based on loading conditions, user requirements, and policy, while performing packet inspection, quality of service enforcement, and other advanced functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If cloud computing functions are centralized in data centers, then processing and storage capacity is improved, but latency and network load increase
Solution Approach 1:
The patent segments cloud computing functions by separating them into centralized data centers and distributed RAN components. Specifically, it divides the network into core network functions (CN) that remain centralized and radio access network functions (RAN) that are distributed at edge locations closer to users. This segmentation allows processing capacity to be maintained centrally while reducing latency through distributed edge computing capabilities.
Solution Approach 2:
The patent introduces a spatial dimension to cloud computing by deploying RAN components at multiple geographic locations (base stations, access points) rather than relying solely on centralized data centers. This creates a multi-dimensional architecture where computing resources are distributed across different spatial locations, bringing processing closer to end users and thereby reducing network latency.
2Device complexity
If RAN and Core Network components are separated, then network architecture simplicity is improved, but integration complexity for cloud computing increases
Solution Approach 1:
The patent implements multi-functionality by designing RAN components that can perform both traditional radio access functions and cloud computing functions. The RAN nodes are equipped with processing units that can execute virtualized network functions, enabling them to serve dual purposes: managing radio communications and providing cloud computing services. This universal approach allows the same infrastructure to handle both connectivity and computing tasks.
Solution Approach 2:
The patent introduces virtualization as an intermediary layer between the physical RAN infrastructure and cloud computing functions. Virtual network functions (VNFs) act as mediators that can be deployed and managed independently on standardized hardware platforms, facilitating seamless integration between RAN and Core Network components without requiring tight coupling or custom hardware.
3Adaptability or versatility
If non-radio functionality is introduced into RAN, then service capability is improved, but processing and storage capacity concerns arise
Solution Approach 1:
The patent segments processing functions by identifying which non-radio functions should be executed at RAN nodes versus which should remain at centralized data centers. Radio access functions and latency-sensitive services are processed locally at RAN, while computationally intensive functions that do not require real-time processing are handled centrally. This segmentation allows RAN to gain service capability without being overwhelmed by processing demands.
Solution Approach 2:
The patent applies partial action by selectively introducing only the necessary non-radio functions at RAN nodes rather than implementing all cloud computing functions distributed. The system deploys virtualized network functions that are specific to RAN operations (such as packet inspection, quality of service enforcement, and local caching) while leaving other functions to centralized infrastructure, thus avoiding excessive processing burden.
4Adaptability or versatility
If multiple radio access networks are integrated, then network versatility is improved, but selection and management complexity increases
Solution Approach 1:
The patent merges multiple radio access networks (Wi-Fi, LTE, 3G) into a unified RAN architecture that presents a single management interface to users and core network. The system consolidates control functions and implements unified resource management across different access technologies, allowing seamless operation of heterogeneous networks without requiring separate management systems for each technology.
Solution Approach 2:
The patent utilizes parameter-based management where the system dynamically adjusts operational parameters (such as bandwidth allocation, power levels, and routing decisions) based on network conditions, user requirements, and policy constraints. This parameter-driven approach allows flexible management of multiple access technologies through standardized control mechanisms rather than technology-specific configurations.
