Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G satellite RANs face challenges in providing minimum data rates and latency due to the distance and size of emulated cells, which affect the quality of user experience, especially during connection initiation, and existing congestion control methods can hinder new connections.
Innovation Solution
A method for managing communications by estimating the number of individual phases in a data stream, allocating resources for target rates at connection initiation, and dynamically adjusting these phases based on available radio resources and user equipment needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If satellite RAN emulates large terrestrial cells to improve coverage area, then coverage area is improved, but data rate and latency deteriorate due to distance and cell size
Solution Approach 1:
The patent segments the data stream into multiple individual phases, each associated with a target rate. This allows the system to allocate different phases to different user equipments based on their specific rate requirements, enabling simultaneous connections with varying resource allocation while maintaining high data rates for each user despite the large coverage area
Solution Approach 2:
The patent dynamically adjusts the allocation of individual phases based on available radio resources and detected connection needs. The system continuously monitors resource availability and reallocates phases to maintain optimal data rates for active connections, adapting to changing conditions in the large satellite-covered area
2Area of stationary object
If satellite RAN emulates large terrestrial cells to improve coverage area, then coverage area is improved, but latency deteriorates due to distance and cell size
Solution Approach 1:
The patent performs preliminary actions by obtaining the number of individual phases and their associated target rates before connections are established. This advance preparation allows the system to quickly allocate appropriate resources when connections are detected, reducing the time penalty associated with large satellite cells
3Productivity
If congestion control methods are applied to manage data transmission, then resource utilization is improved, but new connections are hindered
Solution Approach 1:
By segmenting the data stream into multiple individual phases, the system can allocate specific phases to new connections without being constrained by existing congestion control mechanisms. This segmentation allows new connections to be established by assigning them to available phases, maintaining both resource utilization and connection adaptability

AI summary
A method for managing communications implementing a mobile intermediate device generating a radio beam that covers a radio cell, implementing for a data stream of the radio beam: obtaining the number of individual phases each associated with a target rate in the stream for transmissions from the mobile intermediate device to the radio cell: detecting a start of a connection of a user device present in the radio cell to a data server via the mobile intermediate device; if an individual phase is available for the stream: transmitting connection start data from the data server between the mobile intermediate device and the user device at the target rate of the individual phase until a stop criterion; if no individual phase is available for the stream: transmitting connection start data from the data server between the mobile intermediate device and the user device at a rate lower than the target rate.
