Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The patent segments the network into hierarchical levels with mobile base-stations operating as relays between user equipment and fixed base-stations. This segmentation enables extended coverage area by distributing network functions across multiple mobile nodes while maintaining connection to the core infrastructure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Mobile base-stations serve as intermediary relay nodes between user equipment and fixed base-stations. These mobile relays extend the effective coverage area by bridging the gap between distant users and the fixed infrastructure, solving the limited range problem in rural areas.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 1:

Mobile base-stations are designed with multi-functionality, serving simultaneously as user equipment, relay nodes, and base-stations. This universal design reduces overall system complexity by eliminating the need for separate dedicated relay infrastructure while extending coverage area.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs dynamic hierarchical architecture where mobile base-stations can adapt their roles and positions based on network conditions. This dynamic flexibility allows the system to manage complexity through adaptive resource allocation rather than rigid infrastructure planning.

Inventive Principle:

Principle #15Dynamics

Solution Approach 1:

The system performs preliminary bandwidth allocation and QoS parameter configuration before multi-hop relay communication begins. By pre-configuring resource allocation parameters and hierarchical relationships, the system simplifies real-time network management while maintaining efficient bandwidth utilization.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The hierarchical relay architecture implements feedback mechanisms where mobile base-stations report network conditions and resource usage to higher-level nodes. This feedback enables dynamic bandwidth allocation that improves efficiency while automating management decisions to reduce complexity.

Inventive Principle:

Solution Approach 1:

The system dynamically adjusts antenna beam directions and relay node positions to track moving users while maintaining focused signal transmission. This dynamic adaptation allows directional antennas to preserve high data-rates even in mobile environments by continuously optimizing beam alignment.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Mobile base-stations autonomously adjust their directional antenna orientations and relay relationships based on detected user positions and network conditions. This self-service capability maintains high data-rates through automatic beam tracking without requiring complex centralized control for each mobility event.

Inventive Principle:

Principle #25Self-service
