Group Communication Token System for Road Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Push-to-Talk over Cellular (PTT) technologies face limitations in enabling spontaneous, local group communication among road users, particularly in terms of priority-based communication, dynamic group size adjustment, and anonymous, non-binding interaction, which can be disrupted by intentional participants.
Innovation Solution
A method and device that utilize a token-based permission system, dynamic radius adjustment, and anonymous participant identification to facilitate fair and regulated communication, with a human moderator to manage talk sessions and prevent disruption, allowing participants to form groups based on location, direction, or interests, and enabling visual feedback and rating of speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If push-to-talk communication is implemented using packet-switched mobile networks, then voice communication can be transmitted to multiple recipients simultaneously, but communication delay increases due to packet routing and server processing
Solution Approach 1:
The system establishes communication groups and pre-configures transmission paths before actual voice communication occurs. Group members are pre-identified and registered with the server, so when push-to-talk is activated, the server can immediately route packets along pre-established paths rather than discovering recipients in real-time, reducing transmission delay
2Adaptability or versatility
If multiple participants can speak simultaneously in a group, then communication freedom increases, but communication quality deteriorates due to lack of priority management and simultaneous transmission conflicts
Solution Approach 1:
The system implements dynamic priority management where transmission rights are allocated based on real-time conditions. The server controls which participants can transmit at any given moment, dynamically adjusting who speaks based on group needs, emergency situations, or communication flow requirements. This maintains communication freedom while ensuring quality through controlled access
Solution Approach 2:
The server acts as an intermediary that mediates between multiple participants wanting to speak simultaneously. It receives transmission requests from multiple users, manages the queue, and grants transmission rights appropriately, preventing direct conflicts between simultaneous transmissions while maintaining the appearance of free communication for users
3Ease of operation
If group communication is anonymous and non-binding, then participant privacy and freedom are improved, but system reliability worsens due to potential disruption by intentional participants
Solution Approach 1:
The system implements feedback mechanisms where participant behavior is monitored and evaluated. Even in anonymous communication, the server tracks transmission patterns, and participants can receive feedback from the group or the system itself. This allows the system to identify and manage disruptive behavior while maintaining anonymity, balancing privacy with reliability
4Adaptability or versatility
If the communication group size is dynamically adjusted, then adaptability to different situations is improved, but system complexity increases due to continuous group reconfiguration
Solution Approach 1:
The system implements self-service mechanisms for group management where participants can automatically join or leave groups based on predefined criteria such as location, device type, or communication needs. The server automatically manages group composition without requiring manual intervention for each change, reducing the perceived complexity for users while maintaining dynamic adaptability
Data Source
AI summary
The invention relates to a method for communication between road users, which users are able to connect via at least one communication interface for communication with a server, wherein, in the method, the following steps are carried out on the server in order to set up communication: establishing spatial and thematic information for determining communication subscribers; determining a group of communication subscribers taking the spatial and thematic information as a basis, wherein a spatial region is defined in order to spatially limit the communication subscribers and wherein at least one technological aspect and/or an interest-based aspect is taken as a basis for thematic limitation by the server; and issuing permission for the road users to communicate data on the basis of the server prioritising the data transmitted to the server by the road users as soon as the group has been determined, wherein the spatial and thematic information is ascertained from the mean value of the spatial coordinates of the road users and the relevant average speed and average direction of the road users.
