Cellular Network Reflection Entity for Localized Multicast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based services in cellular communication networks face challenges in efficiently distributing messages to terminals within a defined spatial zone, leading to potential network overload and delays, especially for time-critical events like road traffic hazards.
Innovation Solution
A system that automatically operates service source and destination terminals in a connected mode within a spatial zone, using a reflection entity to rapidly distribute messages by recognizing and reflecting payload content directly to terminals with a predetermined spatial relationship, thereby reducing processing and radio resource requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If terminals are operated in connected mode within a spatial zone, then message delivery speed is improved, but network load increases
Solution Approach 1:
The patent applies local quality by operating terminals in connected mode only within a specific spatial zone rather than network-wide. The reflection entity determines the spatial zone and selectively establishes connected mode for terminals located within this zone, thereby improving message delivery speed for relevant terminals while limiting the increase in network load to only the affected local area.
Solution Approach 2:
The system performs preliminary action by pre-establishing connected mode for terminals before message transmission occurs. When a terminal enters the spatial zone, the reflection entity activates connected mode in advance, ensuring that when messages need to be transmitted, the terminal is already in the appropriate state for fast communication, thus reducing latency without requiring connected mode to be active continuously network-wide.
2Reliability
If a dedicated channel is allocated for terminals in connected mode, then message transmission reliability is improved, but network resources are consumed
Solution Approach 1:
The patent applies local quality by allocating dedicated channels only for terminals within the spatial zone that require connected mode operation. The reflection entity identifies which terminals need dedicated channel allocation based on their location and service requirements, thereby improving message transmission reliability for these specific terminals while avoiding the consumption of network resources for terminals outside the spatial zone.
3Adaptability or versatility
If reflection entity processes all terminals, then service coverage is improved, but processing complexity increases
Solution Approach 1:
The reflection entity applies local quality by focusing its processing efforts only on terminals located within the spatial zone. Instead of processing all terminals in the network, the reflection entity determines the spatial zone and selectively processes messages for terminals within this zone, thereby maintaining service coverage for the relevant area while significantly reducing processing complexity.
Solution Approach 2:
The system applies segmentation by dividing the network into spatial zones and processing terminals segment-by-segment rather than handling all terminals uniformly. The reflection entity segments the terminal population based on their location relative to the spatial zone, which simplifies processing by focusing only on the relevant segment (terminals within the zone) while maintaining comprehensive service coverage for that segment.
