Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile data networks face challenges in upgrading infrastructure to handle increasing data demands without incurring significant economic costs, as replacing existing equipment with newer, more efficient technology is expensive and logistically difficult, especially for older 3G networks still transitioning to 4G.
Innovation Solution
The implementation of a Mobile Internet Optimization Platform (MIOP) that includes breakout components in the radio access network to offload data processing to edge applications, allowing existing equipment to maintain subscriber sessions while routing data-intensive tasks to neighboring basestations via an overlay network, thereby enhancing data processing capacity without requiring extensive hardware or software changes.

Engineering Contradiction Analysis
1Productivity
If existing mobile data network equipment is replaced with newer technology to handle increasing data demands, then data processing capacity is improved, but economic costs and implementation difficulty increase significantly
Solution Approach 1:
The patent segments the mobile data network into core network infrastructure and edge computing nodes (basestations). Data processing functions are divided between these segments, with edge applications running at the basestation level to handle local data demands without requiring core network upgrades. This segmentation allows incremental deployment of new capabilities while preserving existing core infrastructure.
Solution Approach 2:
The patent introduces an overlay network as an intermediary layer between existing basestations and the core network. This overlay network enables communication and coordination between basestations for application offloading without requiring changes to the underlying physical infrastructure. The intermediary layer provides new functionality while maintaining compatibility with legacy equipment.
2Speed
If microwave links are replaced with fiber optic cable to boost throughput, then data transmission speed is improved, but economic costs increase significantly
Solution Approach 1:
Instead of upgrading all microwave links to fiber optic cable, the patent implements application offloading at select basestations where edge applications are deployed. This partial action provides sufficient throughput improvement for data-intensive applications without requiring comprehensive infrastructure replacement. The overlay network enables efficient data routing that maximizes utilization of existing microwave link capacity.
3Productivity
If edge applications are hosted locally at every basestation, then data processing capacity is improved, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent creates a universal overlay network that enables any basestation to function as an edge computing node when needed. Rather than requiring specialized hardware at each basestation, the overlay network provides multi-functional capabilities that allow basestations to dynamically host or access edge applications based on demand. This universal approach simplifies deployment by using existing infrastructure for multiple purposes.
Solution Approach 2:
The overlay network implements self-service mechanisms where basestations can autonomously discover and access edge applications hosted at neighboring basestations. The system automatically routes data requests through the overlay network to the appropriate application instance without requiring manual configuration or complex coordination. This self-service capability reduces deployment complexity and operational overhead.

AI summary
Mobile network services are performed in a mobile data network that includes a radio access network and a core network. A breakout component in the radio access network breaks out data coming from a basestation connected to user equipment, and hosts edge applications that perform one or more mobile network services at the edge of the mobile data network. When a breakout component is not running a needed edge application, and the needed edge application is running in a neighboring basestation, the breakout component can route the request for the needed edge application to the neighboring basestation via the overlay network. The neighboring basestation processes the request using the needed edge application, then returns the data to the original basestation via the overlay network. The original basestation thus maintains the subscriber session with the user equipment while offloading the work of the needed application to a neighboring basestation.
