Wireless Network Congestion Control via Geographical Node Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks lack effective traffic congestion control methods, particularly for high-profile and emergency locations that require higher priority during emergency situations.
Innovation Solution
A method and apparatus that determine traffic congestion thresholds, identify critical geographical locations, and assign higher priorities to network nodes in proximity to these areas, allowing for optimized congestion control by minimizing access limitations and load shedding for prioritized nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control and load shedding techniques are applied to protect the mobility manager from overloading, then the mobility manager is protected from overloading, but existing wireless communication networks are unable to provide traffic congestion control for high profile and emergency locations that require higher priority
Solution Approach 1:
The patent segments the network into different priority levels by identifying critical geographical locations and assigning higher priority to network nodes in proximity to these locations. This creates differentiated service levels where emergency and high-profile locations receive preferential treatment during congestion, resolving the contradiction between general overload protection and specific location-based control capability.
Solution Approach 2:
The patent applies local quality by assigning different priority levels to different network nodes based on their geographical proximity to critical locations. Network nodes near emergency or high-profile locations are assigned higher priority, while other nodes follow standard congestion control. This localized differentiation enables the system to provide both general protection and specific location-based control simultaneously.
2Ease of operation
If existing access control techniques are used during emergency situations, then call flow is distributed or terminated, but these techniques cannot provide higher priority for high profile and emergency locations
Solution Approach 1:
The patent performs preliminary action by pre-identifying critical geographical locations and pre-configuring network nodes in proximity to these locations with higher priority levels before emergency situations occur. This advance preparation ensures that when congestion happens, critical locations already have their priority established, eliminating the need for reactive priority assignment and ensuring reliable priority assurance.
3Device complexity
If traffic congestion control is implemented without geographical awareness, then network resources are managed uniformly, but critical locations cannot receive prioritized service
Solution Approach 1:
The patent introduces a new dimension to congestion control by incorporating geographical location information into the priority assignment mechanism. Instead of uniform network-wide control, the system adds spatial awareness to differentiate between critical and non-critical locations, enabling location-based priority service while maintaining relatively simple congestion control logic through geographical filtering.

AI summary
In a wireless communication system, a method and apparatus for controlling traffic congestion includes determining that the traffic congestion at a plurality of geographical locations in the wireless communication network is above a predetermined threshold value. At least one geographical location of the plurality of geographical location is identified, wherein the identification of the at least one geographical location is based on the determination of the traffic congestion in the plurality of geographical location. At least one network node of a plurality of network nodes located in proximity of the identified geographical location is selected and assigned a first level of priority during congestion control.
