Dynamic Jitter Buffer Congestion Abatement for GSM Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies due to static and unresponsive compression/suppression protocols, leading to inadequate bandwidth optimization and poor congestion management, resulting in high operational costs and resource consumption.
Innovation Solution
A dynamic system and method that detects congestion by measuring receive jitter buffer levels, prioritizes data packets, and systematically drops individual subrates to alleviate congestion, ensuring critical information is not affected, while gradually adding back timeslots to prevent system overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static compression/suppression protocols are used, then system complexity is reduced, but bandwidth efficiency and congestion response capability deteriorate
Solution Approach 1:
The patent implements dynamic compression/suppression protocols that adapt to real-time network conditions. The system continuously monitors congestion levels and adjusts compression parameters dynamically, transforming the static protocol into a responsive system that optimizes bandwidth efficiency while managing congestion effectively.
Solution Approach 2:
The patent employs feedback mechanisms where the system monitors network congestion conditions and uses this information to adjust compression parameters. The congestion detection unit provides continuous feedback about network state, enabling the protocol to self-optimize and maintain high bandwidth efficiency without requiring complex manual configuration.
2Productivity
If entire packets are dropped during congestion, then congestion is alleviated quickly, but information loss increases
Solution Approach 1:
The patent segments packets into individual subrates that can be independently handled during congestion. Instead of treating each packet as an indivisible unit, the system divides it into separable components (subrates), allowing selective dropping of only the necessary portions to relieve congestion while preserving critical information in other subrates.
Solution Approach 2:
The patent applies different quality levels to different subrates within packets. Critical subrates are protected from dropping while non-critical subrates are selectively dropped during congestion. This local differentiation of quality enables congestion relief without proportional information loss across the entire packet.
3Quantity of substance
If more T1/E1 lines are implemented, then bandwidth capacity increases, but system cost increases
Solution Approach 1:
The patent implements dynamic compression that adapts to traffic patterns, enabling the system to maximize utilization of existing T1/E1 lines. By dynamically adjusting compression parameters based on actual network conditions, the system extracts more bandwidth capacity from the same physical infrastructure, reducing the need for additional expensive lines.
Solution Approach 2:
The patent changes compression parameters dynamically based on network conditions, traffic types, and congestion levels. This parameter adaptation allows the system to optimize bandwidth utilization across existing T1/E1 lines, effectively increasing capacity without adding physical infrastructure and thereby reducing operational costs.
Data Source
AI summary
An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and operable to receive a plurality of packets associated with a communications flow, the packets including a plurality of subrates. The cell site element is further operable to detect a congestion condition via a measurement of a level in a receive jitter buffer. When the congestion condition exists, individual subrates can be dropped from subsequent backhaul packets until congestion subsides. Single timeslots of the flow are systematically added back during a configured time interval such that congestion abatement will back-off gradually. In more particular embodiments, the cell site element can be informed that congestion exists, whereby a congestion level is assigned to a collection of the subrates. In addition, the cell site element prioritizes the subrates and removes individual samples from one or more of the packets.
