Solution Overview
Problem
Current communication systems, particularly in tactical LTE and 5G environments, face challenges in optimizing radio performance and vehicular integration, leading to suboptimal dimensioning and security for communication equipment in mobile military settings.
Innovation Solution
A communication system with an interconnection network and radio sites, where a remote radio head is interconnected to multiple baseband processing units, allowing for traffic distribution based on application type and security integrity, using advanced protocols like eCPRI and RoE, and featuring a supervision unit for configuring traffic distribution, thereby separating traffic at the baseband level and reducing reliance on core network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a remote radio head is connected to only one baseband processing unit, then the device complexity is reduced, but the resilience and security of communication are degraded
Solution Approach 1:
The patent divides the baseband processing function into multiple independent baseband processing units (at least two units), each capable of handling different traffic types. This segmentation allows the system to separate sensitive traffic from non-sensitive traffic, improving security and resilience without requiring a completely complex rearchitecting of the overall system
Solution Approach 2:
The remote radio head is designed with multi-functionality to support connections with multiple baseband processing units and to handle different types of traffic (sensitive and non-sensitive) through a single interface. This universal design enables flexible traffic distribution while maintaining manageable device complexity
2Reliability
If communication equipment is designed for high security and resilience, then the reliability is improved, but the weight and size of vehicular solutions increase
Solution Approach 1:
By segmenting traffic into sensitive and non-sensitive categories and routing them through different baseband processing units, the system achieves high reliability without duplicating entire communication stacks in multiple locations. This selective segmentation reduces the overall equipment weight compared to a fully redundant architecture
Solution Approach 2:
The patent changes the operational parameters of the baseband processing units by assigning them different traffic handling roles (sensitive vs. non-sensitive traffic). This parameter-based differentiation allows lightweight equipment to achieve high security standards through software/configurable parameters rather than heavy hardware redundancy
3Productivity
If traffic is distributed across multiple baseband processing units, then the productivity and resource utilization are improved, but the device complexity increases
Solution Approach 1:
The remote radio head incorporates self-service capabilities by autonomously determining which baseband processing unit should handle each data packet based on pre-configured criteria (such as traffic type, user ID, or application ID). This self-service approach eliminates the need for complex external control systems, improving productivity while keeping device complexity manageable
Solution Approach 2:
The system performs preliminary action by pre-configuring traffic distribution criteria and rules before actual data transmission begins. This preliminary configuration allows the remote radio head to make rapid routing decisions during operation without complex real-time calculations, thereby improving productivity while maintaining simple operational complexity
