Multi-party Digital Intercommunication Right-to-Speak Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital intercommunication systems in half-duplex mode face inefficiencies in handing over the right to speak among multiple subscribers, leading to prolonged waiting times and collisions in the physical channel, which decrease communication efficiency and waste resources.
Innovation Solution
A method is introduced that uses a combination of time division multiple access (TDMA) and frequency division multiple access (FDMA) to allocate frequency resources, defining logical channels like Forward Traffic Channel (FTCH), Forward Fast Instruction Channel (FFICH), and Backward Slow Instruction Channel (BSICH) to manage the right to speak, where subscribers with higher priority can reserve and hand over the right to speak efficiently via the BSICH, reducing collisions and delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polling rules are used to hand over the right to speak, then every subscriber has a chance to obtain the right to speak, but the waiting time is prolonged and communication efficiency decreases
Solution Approach 1:
The system performs preliminary actions by having subscribers send reservation requests before actually needing to speak. The transmitting subscriber monitors these reservation requests and proactively hands over the right to speak in advance, eliminating the need for long waiting periods during polling cycles while maintaining fair allocation through priority-based selection.
Solution Approach 2:
The system implements feedback mechanisms where receiving subscribers send reservation requests to the transmitting subscriber, who then monitors these requests and decides when to hand over the right to speak based on current transmission status and priority levels. This closed-loop feedback enables dynamic and efficient right-to-speak allocation.
2Speed
If subscribers are allowed to fight for the right to speak, then access speed may improve, but collisions in the physical channel occur causing delays and resource waste
Solution Approach 1:
The transmitting subscriber acts as an intermediary that mediates between multiple receiving subscribers who want to speak. Instead of allowing direct competition that causes collisions, the transmitting subscriber monitors reservation requests from all receiving subscribers and selectively hands over the right to speak to one subscriber at a time, eliminating collisions while maintaining fast access through priority-based selection.
3Stability of the object's composition
If the transmitting subscriber continues to speak despite reservation requests, then current communication is maintained, but the right to speak is not handed over efficiently
Solution Approach 1:
The system dynamically adjusts the transmitting subscriber's behavior based on received reservation requests and priority levels. The transmitting subscriber can continue speaking when appropriate (maintaining stability) but can also hand over the right to speak efficiently when high-priority subscribers request it (improving productivity). This dynamic adaptation resolves the contradiction between maintaining current communication and enabling efficient handover.
