D2D Vehicle Messaging for Logistics Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular communication systems primarily focus on safety applications and lack efficient methods for non-safety applications such as logistics and delivery services, where direct wireless communication between vehicles and infrastructure is needed for coordinating transportation requests and status updates.
Innovation Solution
Implementing Device-to-Device (D2D) communication technologies like dedicated short-range communication (DSRC), cellular Vehicle-to-Everything (C-V2X), and 5G New Radio (NR) for exchanging messages related to transportation services, including request, confirmation, and status updates between user devices and transportation entities like vehicles and servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicular communication systems use traditional infrastructure-based communication methods, then system reliability is maintained, but communication efficiency and real-time information exchange for non-safety applications deteriorate
Solution Approach 1:
The patent introduces a message exchange mechanism using standardized information elements as intermediaries between user devices and transportation entities. These structured messages (request messages, response messages, confirm messages) enable direct D2D communication while maintaining system reliability through standardized protocols, resolving the contradiction between communication efficiency and system reliability.
2Adaptability or versatility
If vehicular communication systems implement comprehensive message exchange protocols for non-safety applications, then service functionality is enhanced, but system complexity increases
Solution Approach 1:
The patent segments the communication protocol into distinct message types (request messages, response messages, confirm messages) with specific information elements for different transportation services. This segmentation allows the system to handle diverse non-safety applications (logistics, delivery, ride-sharing) through modular message structures, enhancing service functionality while managing system complexity through standardized components.
Solution Approach 2:
The patent creates a universal message exchange framework using standardized information elements that can serve multiple transportation services (logistics, delivery, ride-sharing). This multi-functional approach allows a single protocol structure to handle various non-safety applications, enhancing service versatility without proportionally increasing system complexity.
3Loss of time
If direct Device-to-Device communication is implemented for transportation services, then real-time information exchange is achieved, but loss of information increases due to direct communication without infrastructure mediation
Solution Approach 1:
The patent changes the parameter structure of communication messages by defining specific information elements (user device identifier, transportation service type, request parameters, response parameters) that standardize data exchange. This parameter standardization ensures complete and accurate information transmission in direct D2D communication, preventing information loss while achieving real-time exchange for transportation services.

AI summary
A user device and transportation entity, such as a transport vehicle or transport server, perform information exchanges for a transportation service using Device-to-Device (D2D) communications, such as dedicated short-range communication (DSRC), a cellular Vehicle-to-Everything (C-V2X), or a 5G New Radio (NR). The information exchanges, for example, are related to, e.g., logistics and delivery of transportation services. For example, the user device may transmit a transportation request message that includes information elements, such as an identifier, a type of transport device requested, a number of users, requested destination, etc. The transportation entity may transmit a transportation response message accepting or rejecting the request. Additional messages, such as a status request and status of the transportation, as well as messages related to completing the transportation service may be exchanged.
