Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication networks face challenges in managing dynamic and local changes in traffic patterns, leading to reduced quality of service and inefficient resource allocation, especially with diverse application flows and user terminals.
Innovation Solution
Implementing a dynamic, local, and temporary prioritization scheme in communication systems that adjusts transmission priorities based on real-time traffic monitoring, allowing for flexible resource allocation and data flow management.

Engineering Contradiction Analysis
1Device complexity
If a fixed traffic model is used for network dimensioning, then network design becomes simpler, but the network cannot effectively handle dynamic and local traffic changes
Solution Approach 1:
The patent implements dynamic prioritization schemes that can be switched based on detected traffic patterns. The network transitions from a static, fixed traffic model to a dynamic system where prioritization profiles are adjusted in real-time according to actual traffic conditions, allowing the network to adapt to local and temporary traffic changes without requiring complete redesign
Solution Approach 2:
The patent changes the parameter of transmission priority dynamically. By switching between different prioritization profiles that assign different priority levels to various data flows based on detected traffic patterns, the network can adapt its behavior to match actual traffic conditions while maintaining the same physical infrastructure
2Reliability
If admission control and congestion control are used to manage traffic divergence, then QoS can be maintained for admitted users, but the solutions are inflexible and not adapted to networks handling different application data flows
Solution Approach 1:
The patent applies different prioritization profiles to different data flows based on their specific characteristics and requirements. Each application flow can be assigned appropriate priority levels locally, allowing the system to handle diverse application types (voice, data, multimedia) with their specific QoS requirements in a flexible and adapted manner
Solution Approach 2:
The patent dynamically switches between different prioritization profiles based on detected traffic patterns and application types. This dynamic adaptation allows the system to respond to changing traffic conditions and provide appropriate QoS for different application flows without using rigid admission control mechanisms
3Productivity
If transmission scheduling schemes are reduced in congestion control, then overload can be managed, but the time occasions allocated to particular users are reduced
Solution Approach 1:
Instead of reducing transmission time allocation, the patent changes the parameter of transmission priority. By reassigning priority levels to different data flows through profile switching, the system manages congestion by prioritizing critical traffic without reducing the overall transmission opportunities available to users

AI summary
The present invention involves traffic management in a communication system (1) comprising multiple communication terminal (10, 200) that each has data flows presented in transmit buffers (14, 220). The terminals (10, 200) utilize a default priority scheme for selecting data from the buffers (14, 220) to transmit at transmission occasions determined by a schedule scheme. A switching event is detected based on information of an estimate distribution of data flows in a first portion (2) of the system (1). A priority scheme update message is generated based on this event detection. The update message comprises information of a temporary priority scheme that is to be used by terminals (10, 200) in a second portion (2; 5) of the system (1). By using this temporary scheme that assigns new temporary priorities to the data flows, a local shaping of the transmission pattern and data flow distribution in the second system portion (2; 5) is possible.
