Dynamic Wireless Resource Segregation by Traffic Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face interference issues due to the lack of effective management of voice and data traffic, as prior art systems either employ conservative pre-provisioning or ad hoc resource management without differentiating between traffic types, leading to inefficient resource utilization and increased interference levels.
Innovation Solution
A dynamic segregation method for managing wireless resources by separating airlink resources into voice and data resource zones based on real-time demand information, using a server computer to generate and implement an allocation plan that optimizes resource allocation and reduces interference between voice and data traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If voice and data traffic are managed separately in different resource zones, then interference levels are reduced and network efficiency is improved, but device complexity and resource management overhead increase
Solution Approach 1:
The patent divides the wireless resource pool into separate voice resource zones and data resource zones. Voice traffic is allocated to specific resource zones while data traffic uses other zones, preventing mutual interference between the two traffic types. This segmentation allows independent optimization of resources for each traffic type, reducing overall interference levels in the network.
Solution Approach 2:
The patent introduces a resource management entity that acts as an intermediary between voice and data traffic flows. This entity dynamically allocates and manages the separation of resources, coordinating which resources are assigned to voice traffic and which to data traffic based on current network conditions, thereby reducing interference without requiring direct complex interactions between voice and data systems.
2Object-generated harmful factors
If closed-loop power control is used for voice traffic, then interference is reduced, but the system becomes less effective when traffic transitions to burst transmissions
Solution Approach 1:
The patent implements dynamic resource allocation where the assignment of resource zones to voice or data traffic can change based on current traffic conditions. When voice traffic is active, dedicated voice resource zones are allocated with appropriate power control. When data traffic becomes dominant or voice transitions to burst mode, the system dynamically reassigns resources, ensuring optimal performance for the prevailing traffic type rather than being constrained by static power control mechanisms.
Solution Approach 2:
The patent changes the allocation parameters of wireless resources based on traffic type detection. When burst transmissions are detected, the system modifies resource allocation parameters to suit data traffic characteristics rather than maintaining voice-oriented parameters, thereby maintaining effectiveness across different traffic patterns while still managing interference through appropriate parameter selection for each traffic type.
3Ease of operation
If data traffic is transmitted without power control, then resource allocation is simplified, but interference levels in neighboring cells increase
Solution Approach 1:
The patent segments the resource pool so that data traffic is confined to specific data resource zones separate from voice resources. This spatial segmentation in the resource domain allows data traffic to be transmitted without complex power control while limiting its interference impact to specific zones, preventing widespread interference across the entire network as would occur with uncontrolled data transmissions in shared resources.

AI summary
Systems and methods are described for segregating airlink resources in a wireless communication network by traffic type. When voice data and traffic data are sent simultaneously in a wireless network using a limited set of frequency resources, the data traffic can cause unacceptable interference in the voice traffic. Accordingly, transceivers share their voice traffic and data traffic demands and may allocate portions of an airlink resource into resource zones for exclusive use by voice traffic and data traffic. Within each resource zone, the transmission can be optimally managed for each traffic type, and interference between voice traffic and data traffic is reduced.
