Solution Overview
Problem
Current cell bar schemes in LTE networks are not adaptive to aerial UEs and cannot distinguish between aerial and terrestrial UEs, leading to inefficient radio resource management and network congestion, especially in scenarios like disasters.
Innovation Solution
Implementing a method where base stations broadcast specific aerial cell bar parameters, including height thresholds and service-type-specific bar factors and times, to determine whether an aerial UE should be subjected to an aerial cell bar scheme, allowing for differentiated management of radio resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cell bar parameters are broadcast to all UEs, then network overload is avoided for terrestrial UEs, but aerial UEs cannot receive differentiated cell bar management leading to inefficient radio resource allocation
Solution Approach 1:
The patent segments the cell bar parameters into two distinct sets: conventional cell bar parameters and aerial cell bar parameters. The base station broadcasts both types of parameters, allowing terrestrial UEs to use conventional parameters while aerial UEs utilize aerial-specific parameters. This segmentation enables differentiated resource management for different UE types, resolving the contradiction between maintaining network-wide compatibility and providing aerial-optimized resource allocation.
Solution Approach 2:
The patent applies local quality by providing different cell bar parameters tailored to specific UE types. Aerial UEs receive aerial-specific parameters (including height thresholds and aerial service types) while terrestrial UEs continue using conventional parameters. This localized parameter differentiation ensures that each UE type receives optimized cell bar management suited to its specific characteristics and resource consumption patterns.
2Ease of operation
If aerial UEs are allowed to access the network without differentiation, then network integration is simplified, but network congestion occurs due to higher radio resource consumption by aerial UEs
Solution Approach 1:
The patent implements preliminary action by having the base station pre-calculate and broadcast aerial cell bar parameters before aerial UEs attempt network access. These parameters include height thresholds and service-type-specific bar factors that are computed in advance based on network conditions. This preliminary preparation enables aerial UEs to self-evaluate and regulate their access behavior before consuming significant radio resources, preventing network congestion while maintaining integration simplicity.
Solution Approach 2:
The patent incorporates feedback mechanisms where aerial UEs continuously monitor their height, service type, and the broadcasted aerial cell bar parameters to dynamically adjust their cell bar evaluation. This feedback loop allows aerial UEs to adapt their resource consumption based on current network conditions and their own operational characteristics, balancing network integration ease with resource conservation.
3Measurement precision
If cell bar parameters are customized for different aerial service types, then radio resource management precision is improved, but parameter broadcast complexity increases
Solution Approach 1:
The patent utilizes parameter changes by introducing service-type-specific bar factors and bar times that vary according to different aerial service types (e.g., emergency services, commercial services, recreational services). Each service type has customized parameters that precisely match its resource consumption characteristics and priority level. This parameter differentiation achieves high-precision cell bar evaluation for diverse aerial services while the structured broadcast format manages the complexity through systematic organization.
Solution Approach 2:
The patent applies universality by designing a unified aerial cell bar parameter structure that can accommodate multiple aerial service types through a single broadcast mechanism. The parameter framework includes service type identifiers and corresponding bar factors that can represent various service categories, allowing one broadcast structure to serve multiple service types simultaneously. This multi-functional approach reduces overall system complexity while maintaining precision for each service type.
