Mobile Base Station Bubble Network Isolated Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile base station networks face challenges in maintaining connectivity when disconnected from the public Internet or a mobile operator core network, particularly in providing continuous service to localized users without reliable backhaul connections.
Innovation Solution
A bubble network system is implemented, featuring an isolated base station with a local HetNet Gateway and Evolved Packet Core, allowing for disconnected operation and seamless reconnection when backhaul is restored, utilizing loopback connections and virtualized networks to ensure service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a base station operates independently without connection to the mobile operator core network, then service continuity to localized users is maintained, but network connectivity and access to core network services are lost
Solution Approach 1:
The patent segments the network into a disconnected base station portion and a virtualized core network portion. The base station can operate independently serving localized users while the virtualized core network functions are distributed to other network elements, allowing service continuity without direct core network connection.
Solution Approach 2:
The patent introduces a gateway as an intermediary between the disconnected base station and the virtualized core network. This gateway enables the base station to maintain service continuity while indirectly accessing core network services through the virtualized network architecture.
2Adaptability or versatility
If network resources are virtualized and distributed, then network adaptability and service flexibility are improved, but system complexity increases
Solution Approach 1:
The patent implements a universal gateway that performs multiple functions including serving as an interface between disconnected base stations and the virtualized core network, providing service routing, and enabling resource sharing. This multi-functional approach increases adaptability while managing complexity through consolidation.
Solution Approach 2:
The patent employs dynamic resource allocation and virtualization where network resources can be dynamically assigned and reassigned based on service requirements. This allows the system to adapt to changing conditions while the underlying infrastructure remains manageable through automated resource management.
3Reliability
If a local core network is deployed at each base station location, then service independence and reliability are improved, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent extracts core network functions from the traditional centralized core network and places them in a virtualized form that can be distributed. Instead of deploying full local core networks at each base station, the essential functions are extracted and delivered remotely through the virtualized network architecture.
Solution Approach 2:
The patent uses virtualization to create virtual copies of core network functions that can be accessed by multiple base stations. Rather than deploying physical duplicate core networks at each location, virtual instances are created and shared, reducing deployment complexity while maintaining service independence.
