Wireless Data Flow Priority Mapping for Dynamic QoS Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for resource allocation in wireless communication networks, specifically using Logical Channel (LCH) Mapping Restriction, result in resource waste and inefficiency due to single priority values, limitations in configuring multiple restrictions, and static priority configurations that do not adapt to varying QoS requirements.
Innovation Solution
Configuring plural resource types and differing priorities for data flows, allowing dynamic adjustment of priority based on QoS requirements, and using dynamic grants and configured grants to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single priority value is used for Logical Channel Mapping Restriction, then configuration complexity is reduced, but resource utilization efficiency deteriorates due to resource waste
Solution Approach 1:
The patent segments the single priority value into multiple priority values associated with different resource types (configured grant and dynamic grant). Each resource type can have its own priority value, allowing differentiated resource allocation. This segmentation resolves the contradiction by enabling efficient resource utilization through multi-priority values while maintaining manageable configuration complexity through structured association between resource types and priority values.
Solution Approach 2:
The patent introduces dynamic priority adjustment by allowing the network to configure different priority values for different resource types based on varying QoS requirements. The priority values can be dynamically adjusted through RRC reconfiguration messages, enabling the system to adapt to changing traffic demands. This dynamic capability improves resource utilization efficiency while the structured configuration mechanism keeps complexity manageable.
2Stability of the object's composition
If static priority configuration is used, then system stability is improved, but adaptability to varying QoS requirements deteriorates
Solution Approach 1:
The patent implements dynamic priority configuration where the network can adjust priority values for different resource types through RRC reconfiguration messages. The system maintains stability through structured configuration procedures while enabling adaptability to varying QoS requirements by allowing dynamic modification of priority values based on current traffic conditions and service demands.
Solution Approach 2:
The patent changes the priority parameter from a fixed single value to multiple configurable values associated with different resource types. The network can modify these priority parameters dynamically to match varying QoS requirements, while the structured configuration framework maintains system stability during transitions.
3Adaptability or versatility
If multiple LCH Mapping Restrictions are configured, then resource allocation flexibility is improved, but device complexity increases due to limitation in configuring multiple restrictions
Solution Approach 1:
The patent segments resource allocation into distinct resource types (configured grant and dynamic grant), each with its own priority value and mapping restriction. This segmentation allows multiple restrictions to be configured without increasing overall system complexity, as each resource type can be independently managed. The structured association between resource types and their parameters keeps device complexity manageable while enabling flexible resource allocation.
Solution Approach 2:
The patent creates a universal framework where the same configuration mechanism (RRC signaling with logicalChannelConfig) handles multiple resource types and their associated restrictions. This multi-functional approach allows the system to configure multiple LCH mapping restrictions through a unified procedure, improving resource allocation flexibility while avoiding the complexity increase that would result from separate configuration mechanisms for each restriction type.
Data Source
AI summary
A network node of a telecommunications system comprises node processor circuitry and node interface circuitry. The node processor circuitry is configured to dynamically configure a priority for a data flow between the network node and a wireless terminal. The node interface circuitry is configured to transmit, over a radio interface to the wireless terminal, a message that includes an identification of the dynamic configuration of the priority for the data flow. A wireless terminal comprises terminal interface circuitry configured to receive the message from the network and terminal processor circuitry configured to implement the dynamic configuration of the priority for the data flow to use the data flow to communicate with the network node.
