Dynamic Bearer Profile Assignment for Wireless Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in managing Quality of Service (QoS) and Quality of Experience (QoE) due to high loads, particularly when access nodes become overloaded with data traffic or numerous devices, leading to potential service degradation and inefficient resource utilization.
Innovation Solution
The method involves assigning a first bearer profile to a wireless device based on initial usage data and monitoring criteria, with a second bearer profile being activated when specific conditions are met, allowing for dynamic adjustment of QoS parameters such as QCI level and ARP values to optimize resource allocation and prevent service degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load balancing and congestion management techniques are implemented to prevent service degradation, then QoS and QoE are maintained, but network complexity and resource overhead increase
Solution Approach 1:
The patent implements dynamic bearer profile assignment where the network node continuously monitors usage data and transitions wireless devices between connected and detached modes based on real-time network conditions. This dynamic adjustment allows the system to adapt to changing load conditions without requiring complex permanent configurations, resolving the contradiction between maintaining reliable service and reducing network complexity
Solution Approach 2:
The system changes the operational state parameter of wireless devices by transitioning them between connected and detached modes based on monitored usage criteria. This parameter change enables the network to manage load and maintain QoS/QoE through simple state transitions rather than complex continuous control mechanisms, addressing the technical contradiction
2Productivity
If bearer profiles are dynamically adjusted based on monitored usage data, then resource allocation is optimized, but processing overhead and monitoring complexity increase
Solution Approach 1:
The network node automatically monitors usage data and performs self-service by dynamically assigning bearer profiles without requiring manual intervention or complex external control systems. This self-service approach optimizes resource allocation through automated decision-making based on monitored criteria, resolving the contradiction between improved productivity and reduced processing overhead
Solution Approach 2:
The system implements feedback loops where usage data is continuously monitored and fed back to the network node, which then adjusts bearer profile assignments accordingly. This feedback mechanism enables automated optimization of resource allocation based on actual network conditions, achieving high productivity without requiring complex manual processing
3Reliability
If wireless devices remain in connected mode to ensure service quality, then QoS is maintained, but network resource consumption increases
Solution Approach 1:
The patent dynamically transitions wireless devices between connected and detached modes based on monitored usage criteria and network conditions. This dynamic approach ensures that devices maintain connected status only when necessary for service quality, while transitioning to detached mode during low-activity periods to conserve network resources, resolving the contradiction between reliability and resource consumption
Solution Approach 2:
The system changes the connection state parameter of wireless devices based on usage patterns, transitioning from connected to detached mode when criteria are met. This parameter change allows the network to maintain service quality for active devices while significantly reducing resource consumption for devices in detached mode, addressing the technical contradiction

AI summary
Systems and methods are described for assigning a profile to a wireless device in a communication network. Usage data associated with a wireless device may be received at a first access node. A first bearer profile may be assigned to a data transmission path. The usage data may be monitored for a set of criteria for a predetermined time period. A second bearer profile may be assigned to the data transmission path based on the usage data associated with the wireless device when the set of criteria is met. The wireless device may be detached from the communication network. The wireless device may be updated with the second bearer profile.
