Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods, such as publish/subscribe and cellular communication standards, face challenges in achieving immediate and appropriate direct communication between wireless terminals, particularly in scenarios like vehicle-to-vehicle communication, where scalability and immediacy are crucial but not always guaranteed.
Innovation Solution
A wireless communication system that utilizes a registration unit to associate communication apparatuses with identification information for direct communication, a storage unit to store parameters for direct communication, and a providing unit to share layer 2 identifiers (L2IDs) between vehicles, enabling efficient sidelink communication by associating positions with L2IDs and facilitating direct communication without network intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If publish/subscribe communication method is used, then scalability and ease of implementation are improved, but communication immediacy and speed deteriorate due to predetermined registration and distribution procedures
Solution Approach 1:
The system performs preliminary actions by pre-registering communication apparatuses and pre-distributing identification information (L2IDs) through the information processing apparatus before direct communication is needed. This allows terminals to have communication parameters ready in advance, enabling immediate direct communication when conditions are met without executing registration procedures at the moment of communication.
2Reliability
If cellular communication via base station is used, then communication reliability and coverage are improved, but communication speed and immediacy deteriorate due to network intervention
Solution Approach 1:
The communication system is segmented into two modes: network-mediated communication for reliability and direct communication for speed. The information processing apparatus facilitates this segmentation by distributing L2IDs that enable terminals to switch to direct sidelink communication when in proximity, separating the reliability function (handled by network registration) from the speed function (handled by direct terminal-to-terminal communication).
Solution Approach 2:
The information processing apparatus acts as an intermediary that distributes identification information (L2IDs) to terminals. This intermediary enables terminals to perform direct communication without continuous network intervention, achieving both reliability (through initial intermediary facilitation) and speed (through subsequent direct communication).
3Ease of operation
If L2ID is decided in accordance with position indiscriminately, then direct communication setup is simplified, but communication appropriateness deteriorates as terminals cannot communicate with appropriate partners
Solution Approach 1:
The system applies local quality by distributing different L2IDs to different communication apparatuses based on their specific characteristics and registration information, rather than using a uniform position-based L2ID assignment. This allows terminals to identify and communicate with appropriate partners by matching specific L2IDs, ensuring communication appropriateness while maintaining ease of setup through automated distribution.
4Loss of information
If predetermined topic registration procedure is executed, then information distribution control is improved, but communication efficiency and immediacy deteriorate
Solution Approach 1:
The information processing apparatus performs preliminary action by pre-distributing L2IDs to terminals during registration, before any actual information exchange is needed. This preliminary distribution of identification information eliminates the need for topic registration procedures during active communication, improving efficiency while maintaining control through the initial registration phase.

AI summary
An information processing apparatus registers a communication apparatus that has requested to distribute information and a communication apparatus that has requested to receive the distributed information in association with identification information for identifying a topic of the distribution, and stores, in association with the identification information, a parameter for direct communication between a plurality of communication apparatuses. This information processing apparatus provides a first parameter stored in association with first identification information to a first communication apparatus that has requested to distribute information of a first topic corresponding to the first identification information and a second communication apparatus that has requested to receive the information of the first topic corresponding to the first identification information.
