Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current private mobile networks based on cellular technology have not been seamlessly integrated into enterprise cloud-native technologies like SD-WAN and SSE, and face challenges in global management, system resiliency, and end-to-end quality assurance, while existing access technologies like Wi-Fi and other wireless technologies do not meet specific requirements for coverage, reliability, and latency.
Innovation Solution
A software-defined private mobile network (SD-PMN) is implemented with control plane components deployed at physical locations and SD-WAN PoPs, utilizing IPsec tunnels, DMPO tunnels, and a common IP address for control plane components across multiple SD-WAN PoPs, managed by a PMNO, to provide resilient and seamless failover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Wi-Fi and other access technologies are used for private mobile networks, then deployment flexibility is improved, but coverage, reliability, and latency requirements are not met
Solution Approach 1:
The system segments the network into multiple access technologies (Wi-Fi, cellular, wired) that can be independently deployed and managed. Each access point type handles specific scenarios, allowing the system to meet diverse reliability requirements while maintaining deployment flexibility across different environments.
Solution Approach 2:
The private mobile network system is designed to support multiple access technologies universally, allowing it to function across Wi-Fi, cellular, and wired networks. This multi-functionality enables the system to adapt to different deployment scenarios while maintaining consistent reliability and performance standards.
2Adaptability or versatility
If private mobile network is integrated into enterprise cloud-native technologies, then system compatibility is improved, but global management complexity increases
Solution Approach 1:
The system introduces intermediary management components that bridge the private mobile network with enterprise cloud-native technologies. These intermediaries handle global management functions, reducing complexity by centralizing control while maintaining compatibility across different enterprise systems and platforms.
Solution Approach 2:
The architecture employs a nested structure where the private mobile network is integrated within the enterprise cloud-native ecosystem. Management functions are nested at multiple levels, with local access points nested within regional hubs, which are nested within global management systems, allowing complex global management to be broken down into manageable hierarchical layers.
3Area of stationary object
If dispersed network elements are deployed across multiple locations, then network coverage is improved, but system resiliency and quality assurance become more challenging
Solution Approach 1:
The system implements feedback mechanisms that continuously monitor network elements across dispersed locations. Quality assurance data from each location is fed back to central management, enabling real-time resiliency assessment and automatic adjustment of network parameters to maintain consistent reliability across the expanded coverage area.
Solution Approach 2:
The architecture incorporates redundant network elements and backup pathways at each dispersed location before failures occur. This prior cushioning ensures that if any single element fails, the system maintains resiliency through pre-configured alternatives, preserving quality assurance standards across the entire dispersed network.

AI summary
Some embodiments of the invention provide a method for link optimization in an SD-PMN defined over at least a first site of a first entity and a second site of a PMN-provider. The method configures a first portion of the SD-PMN deployed at the first entity's first site, the first portion of the SD-PMN including at least one or more physical access points for connecting user devices at the first entity's first site to the SD-PMN and one or more control plane components of the SD-PMN. The method configures a first edge router deployed at the first entity's first site to use multiple links including at least one commercial Internet network link between the first edge router and a gateway router deployed in the PMN-provider second site to reach the PMN-provider second site and to perform a multi-link optimization process on the multiple links to establish a secure tunnel for use in communicating with the gateway router.
