Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying rural 2G wireless networks is challenging due to high hardware and infrastructure costs, as well as the need for extensive RF planning and maintenance, which is often not economically viable for operators anticipating a shift to 5G technology.
Innovation Solution
A software-first approach with a virtualized HetNet Gateway (HNG) that provides a unified architecture for 2G, 3G, and 4G networks, enabling self-configuration and self-optimization, reducing hardware requirements, and allowing for flexible backhaul options like satellite or microwave, while virtualizing essential network functions to lower operational expenses and improve deployment speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hardware-based 2G networks are deployed in rural areas, then network coverage can be provided, but hardware costs and infrastructure requirements become excessively high
Solution Approach 1:
The patent replaces traditional hardware-based 2G network infrastructure with a software-defined network approach. The HetNet Gateway virtualizes core network functions (BSC, RNC, MSC) as software instances that can be deployed on standard servers, eliminating the need for expensive dedicated hardware equipment while maintaining 2G network coverage and functionality in rural areas.
Solution Approach 2:
The HetNet Gateway is designed as a multi-functional platform that can simultaneously support multiple network technologies (2G, 3G, 4G, 5G) and various service types (voice, data, video) through a unified architecture. This allows a single deployment to serve multiple purposes and generations of networks, reducing overall infrastructure requirements compared to dedicated hardware for each technology.
2Reliability
If extensive RF planning and maintenance are performed for 2G networks, then network performance can be optimized, but deployment time and operational complexity increase
Solution Approach 1:
The virtualized network architecture enables self-configuration and self-optimization capabilities. The HetNet Gateway automatically provisions network resources, configures parameters, and performs maintenance tasks without requiring extensive manual RF planning and intervention. Network functions can be dynamically adjusted through software updates and configuration changes, reducing deployment time and operational complexity while maintaining performance.
Solution Approach 2:
The patent implements dynamic network management where parameters and configurations can be changed in real-time through software updates rather than requiring physical reconfiguration. This dynamic approach allows the network to adapt to changing conditions and optimize performance without the time-consuming processes associated with traditional hardware-based RF planning and maintenance.
3Reliability
If operators invest in 2G network infrastructure, then current voice service coverage is maintained, but future migration to 5G becomes less flexible
Solution Approach 1:
The HetNet Gateway is designed as a future-proof platform that natively supports multiple network generations (2G, 3G, 4G, 5G) within a single unified architecture. This multi-functional design allows operators to maintain 2G voice services while simultaneously preparing for and migrating to 5G technologies without requiring separate infrastructure investments, thereby preserving both current coverage and future migration flexibility.
Solution Approach 2:
The virtualized architecture enables flexible parameter changes and configuration updates that can adapt the network for different technologies and service requirements. Operators can modify network parameters, switch between technology modes, and reconfigure services through software updates, allowing the same infrastructure to support evolving technological requirements from 2G to 5G migration.
4Ease of operation
If traditional 2G network infrastructure is deployed, then basic voice services are provided, but total cost of ownership remains high
Solution Approach 1:
By replacing expensive hardware infrastructure with software-based virtualization, the patent significantly reduces the capital expenditure required for 2G network deployment. The HetNet Gateway uses standard server hardware running virtualized network functions, eliminating the need for costly dedicated telecom equipment while maintaining the ability to provide comprehensive voice and data services.
Solution Approach 2:
The patent combines multiple network functions (BSC, RNC, MSC, gateway functions) into a single integrated HetNet Gateway platform. This consolidation eliminates the need for separate dedicated hardware for each function, reducing overall equipment costs and simplifying the infrastructure required for 2G service provision while maintaining operational capabilities.
