Region-Based Information Processing for C-V2X Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional C-V2X systems face inefficiencies in processing and computing resource consumption due to excessive information processing by mobile terminal devices, which affects response times and battery life, especially for vulnerable road users, as they need to handle irrelevant data related to their travel routes.
Innovation Solution
The system employs an application service server and user equipment that utilize geographic information services to convert location information into identification information, allowing for region-based processing and filtering of relevant data, reducing unnecessary computations by classifying location information as specific reference objects and generating preprocessed messages for user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile terminal devices process all information within base station service range, then complete information coverage is achieved, but computing resource consumption increases excessively
Solution Approach 1:
The patent segments the base station service range into multiple geographic regions (cells) and further divides each cell into grid units. This hierarchical segmentation allows terminal devices to process information at a finer granular level (grid level) rather than processing all information across the entire service range, significantly reducing unnecessary computing operations while maintaining complete information coverage where needed.
Solution Approach 2:
The patent implements local quality by allowing terminal devices to process information selectively based on their specific geographic location and service requirements. Each grid unit can have customized processing rules and information filtering criteria tailored to local characteristics, enabling devices to focus computational resources only on relevant local information rather than uniformly processing all information across the entire service range.
2Reliability
If mobile terminal devices process all information within service range, then no information is missed, but response time deteriorates due to excessive processing
Solution Approach 1:
The patent performs preliminary actions by pre-dividing the service range into grids and pre-establishing information filtering rules for each grid. When terminal devices receive information, they can quickly determine relevance by comparing grid locations rather than processing all information sequentially. This pre-structured approach enables rapid filtering and significantly reduces application response time while ensuring no relevant information is missed.
3Measurement precision
If geographic location is calculated for each message, then precise location information is obtained, but unnecessary computing operations increase
Solution Approach 1:
The patent uses grid identification codes as simplified copies or proxies for precise geographic coordinates. Instead of calculating and comparing detailed geographic locations for each message, the system uses pre-assigned grid IDs that represent specific geographic areas. This copying approach maintains sufficient location precision for V2X applications while dramatically reducing the computational complexity of location-based filtering and message processing.

AI summary
An application service server, a region-based information processing method, and user equipment are provided. In the method, an initial message is received, identification information is determined according to the location information of the initial message, and a preprocessed message is generated. The initial message includes a notification content corresponding to the location information, and the location information is defined by a geographic coordinate system. The identification information is provided by a geographic information service. The preprocessed message includes the notification content and the identification information.
