Coordinated Satellite Link Access via Data Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks are inefficient due to uncoordinated access from low-bandwidth devices, leading to high volumes of useless data transmission, which hampers the commercial viability of large-scale sensor network deployments.
Innovation Solution
Implementing data profiles that allow each hub to receive and manage timing and preamble codes for data sources across a satellite link, ensuring synchronized communication and efficient use of shared network resources by allocating different preamble codes to devices reporting within a margin of time, thus reducing packet interference and redundant data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uncoordinated access is used by low bandwidth devices, then device deployment complexity is reduced, but network resource efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-allocating preamble codes to devices based on their data sources and reporting schedules before actual data transmission occurs. The network management element distributes these codes in advance, allowing devices to transmit data in a coordinated manner without real-time negotiation, thus maintaining deployment simplicity while improving network efficiency.
Solution Approach 2:
The patent introduces an intermediary mechanism (preamble code allocation system) between devices and the network medium. The network management element acts as a mediator that coordinates access by assigning unique preamble codes to different data sources, enabling efficient resource utilization without requiring complex device-to-device coordination.
2Reliability
If different preamble codes are allocated to data sources reporting within a margin of time, then packet collision is reduced, but system complexity increases
Solution Approach 1:
The system segments the network access space by assigning unique preamble codes to different data sources. This segmentation allows simultaneous transmissions from multiple devices to be distinguished at the receiver, reducing packet collisions while maintaining manageable system complexity through code-based separation rather than complex temporal scheduling.
3Productivity
If coordinated timing control is implemented, then data transmission efficiency is improved, but control overhead increases
Solution Approach 1:
Timing coordination is established in advance through preamble code allocation rather than requiring continuous control messages during data transmission. The preliminary assignment of codes with implicit timing relationships reduces the need for ongoing control overhead while maintaining efficient coordinated transmission.

AI summary
Apparatuses, methods, and systems for coordinated access to a wireless link through data profiles are disclosed. One method includes receiving through the wireless link, by each hub associated with a base station, one or more data profiles from a network management element, receiving, by each hub, data from data sources associated with the hub, controlling, by each hub, a timing of communication of the data for each of the data sources from the hub to the base station through the wireless link based on the one or more data profiles, allocating preamble codes to each of the data sources, wherein different preamble codes are allocated to different data sources of different hubs that report within a margin of time of each other, and including the allocated preamble codes with the data of each of the data sources.
