Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G core network architecture lacks enhanced coordination capabilities beyond those of 4G/LTE, necessitating a new network architecture for efficient coordination across 2G/3G/4G/5G and heterogeneous networks.
Innovation Solution
A distributed cloud coordination server architecture is introduced, utilizing a fabric of coordination servers, such as Parallel Wireless HNGs, which provide virtualizing gateways with single IP addresses for ingress and egress, dynamically creating virtual machines or containers to manage workloads and present a unified network element, allowing for scalable and redundant operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional 5G core network architecture is used, then the network structure is simple and similar to 4G, but coordination capabilities are limited and insufficient for heterogeneous networks
Solution Approach 1:
The patent segments the core network coordination function into distributed coordination servers deployed across multiple locations. Each coordination server handles coordination for a specific subset of radio access nodes, dividing the overall coordination task into manageable segments. This segmentation enables enhanced coordination capabilities while maintaining manageable system complexity through modular deployment.
Solution Approach 2:
The patent introduces a new dimensional aspect to the network architecture by adding coordination servers as an intermediate layer between radio access nodes and the core network. This dimensional addition provides enhanced coordination capabilities without fundamentally redesigning the entire network stack, allowing 5G to build upon existing 4G infrastructure while adding necessary coordination functions.
2Adaptability or versatility
If coordination servers are distributed throughout the network, then coordination capability is enhanced, but network architecture complexity increases
Solution Approach 1:
The coordination servers are designed with multi-functionality, capable of handling various coordination tasks including inter-RAT coordination, load balancing, mobility management, and resource allocation. This universal design allows a single coordination server implementation to address multiple network challenges, enhancing coordination capability while avoiding the need for separate specialized servers for each function.
Solution Approach 2:
The coordination servers act as intermediary elements between radio access nodes and the core network, mediating coordination functions. This intermediary layer simplifies the overall architecture by centralizing coordination logic in dedicated servers rather than distributing it across all network elements, thereby enhancing coordination capability while managing complexity through functional consolidation.
3Adaptability or versatility
If virtual machines or containers are dynamically created to manage workloads, then network flexibility and scalability are improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic virtual machine and container creation based on real-time workload conditions. When coordination load exceeds thresholds, virtual resources are automatically provisioned; when load decreases, resources are released. This dynamic behavior provides network flexibility and scalability while managing complexity through automated resource management rather than static over-provisioning.
Solution Approach 2:
The coordination system incorporates self-service capabilities where the network automatically monitors its own workload conditions and triggers appropriate resource creation or release without external intervention. This self-service approach enables flexible adaptation to changing network conditions while reducing operational complexity by eliminating manual resource management.
