TDMA Slot Assignment via Access Code Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional TDMA systems have inefficiencies in assigning inbound slots to subscriber radios, particularly in trunked radio systems where a single slot is assigned per superframe, limiting data transmission efficiency.
Innovation Solution
A method and system that utilize an inbound reservation scheduling message with subscriber access code fields to dynamically assign multiple inbound transmission slots to subscriber radios, allowing for efficient data transmission by mapping encoded data into TDMA time slots and arranging them into superframes, enabling multiple slot assignments and improved resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single inbound slot is assigned to a subscriber radio in a single superframe, then the system maintains simplicity in slot assignment, but data transmission efficiency is limited
Solution Approach 1:
The patent implements dynamic slot assignment where the number of inbound slots assigned to each subscriber radio varies based on data transmission needs. The base station dynamically determines slot allocations in each superframe, allowing subscriber radios to transmit during one or multiple inbound slots depending on their data buffer status, thereby improving transmission efficiency without permanent system complexity
Solution Approach 2:
The base station performs preliminary assessment of data transmission requirements before slot assignment. By evaluating the number of message bits to be transmitted and predicting future data arrivals, the system pre-determines optimal slot allocations, avoiding reactive complexity while maximizing productivity
2Productivity
If multiple inbound slots are assigned to subscriber radios, then resource utilization improves, but message bit constraints become more significant in narrowband systems
Solution Approach 1:
The patent applies partial action by assigning only the necessary number of inbound slots based on actual data transmission requirements. Rather than allocating all available slots to every subscriber radio, the system calculates the precise number of slots needed and assigns only that amount, maximizing resource utilization while avoiding excessive message bit constraints
Solution Approach 2:
The system dynamically changes the parameter of slot assignment based on message bit constraints. When narrowband conditions exist, the base station adjusts slot allocations to ensure message bits fit within available capacity, optimizing the balance between resource utilization and information loss prevention

AI summary
A method for assigning slot reservations to subscriber radios in a TDMA communications system, where data is arranged into a series of superframes, includes an inbound signaling protocol having a plurality of inbound transmission slots. An outbound signaling protocol includes an inbound reservation scheduling slot, which includes a plurality of subscriber access code fields. Each subscriber access code field corresponds to at least one of the inbound transmission slots. Each subscriber access code field may store a subscriber access code associated with a subscriber radio. The inbound reservation scheduling message includes a subscriber access code in at least one of the subscriber access code fields. As such, the subscriber radio associated with the subscriber access code may transmit data during the inbound transmission slot corresponding to the subscriber access code in which the subscriber access code field is stored.
