Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in managing short addresses for end point devices, including inefficient timer management leading to reduced address availability, bandwidth wastage, and address synchronization issues, which affect data capacity and throughput.
Innovation Solution
Implementing a wireless communication system that uses a narrow band, time slotted communication protocol with an RF site device managing short address assignment and reassignment based on reservation requests, employing a CSMA/CD protocol for random access channels and a scheduler module to determine and update the maximum limit of reserved time slots, ensuring efficient address allocation and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the timer is set too long to release short address assignment, then address stability is improved, but the number of available short addresses decreases
Solution Approach 1:
The patent implements dynamic timer management where the intermediate device adjusts timer durations based on actual communication needs. The timer is extended when data transmission is detected and shortened when idle, allowing the system to adaptively balance address stability with address availability. This dynamic adjustment resolves the contradiction by making the timer duration flexible rather than fixed.
Solution Approach 2:
The system employs feedback mechanisms where the intermediate device monitors data transmission status and uses this information to adjust timer durations. When data is received, the timer is extended to maintain address assignment; when no data is received, the timer is shortened to release the address. This feedback loop enables the system to optimize both stability and availability simultaneously.
2Quantity of substance
If the timer is set too short to release short address assignment, then address availability is improved, but bandwidth is wasted due to frequent reassignment
Solution Approach 1:
The patent uses dynamic timer adjustment where the intermediate device extends the timer duration when data transmission is detected. This prevents premature address release and subsequent reassignment, thereby reducing bandwidth wastage. The timer is only shortened when clearly idle, optimizing the balance between address availability and bandwidth efficiency.
Solution Approach 2:
The system monitors data transmission feedback to determine when to extend or shorten timers. This feedback mechanism prevents premature address release and reassignment, reducing unnecessary bandwidth consumption while maintaining address availability when needed.
3Device complexity
If the intermediate device timer and end point device timer are not synchronized, then device complexity is reduced, but address conflicts occur between end point devices
Solution Approach 1:
The patent introduces the intermediate device as a mediator that manages timer synchronization between end point devices. The intermediate device coordinates timer durations and ensures proper address assignment by acting as a central authority. This mediator approach maintains reliability without requiring direct synchronization between all end point devices, thus managing complexity.
Solution Approach 2:
The system performs preliminary timer configuration and coordination at the intermediate device before address assignment occurs. By pre-establishing timer parameters and synchronization protocols at the intermediate device level, the system prevents address conflicts before they occur, ensuring reliability without complex real-time synchronization between end point devices.

AI summary
Systems, devices, and methods of managing short addresses in a wireless communication system include receiving reservation requests on a random access channel from subscriber units at a radio frequency (RF) site such that the reservation requests includes a minimum number of requested time slots for data transmission between a subscriber unit and the RF site, and a subscriber long address. Further, for each of the reservation requests, the RF site selects a subscriber short address for the respective subscriber unit as well as transmitting the selected subscriber short address to the respective subscriber unit on a RF site channel. In addition, the RF site determines a short address transmission schedule for the subscriber units as well as transmitting a schedule message to the subscriber units on a schedule channel such that the schedule provides slot assignments for data transmissions by subscriber units according to their assigned short addresses.
