VoLTE Silent Section Priority Control for Emergency Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During emergencies like disasters, existing communication systems face challenges in managing network congestion while maintaining communication quality, leading to reduced capacity and potential loss of priority for users with lower call priority levels.
Innovation Solution
Implementing a state-of-emergency mode in VoLTE systems that detects silent sections in voice packets, lowers their priority, and allocates resources accordingly, allowing for efficient congestion control without significantly reducing the number of accommodated users by prioritizing voiced sections and optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication regulation is implemented during emergencies to reduce traffic, then network congestion is relieved, but the number of users that can be accommodated decreases
Solution Approach 1:
The patent applies local quality by differentiating treatment between voiced sections and silent sections of voice packets. Voiced sections maintain normal priority levels while silent sections have their priority reduced during emergencies. This localized differentiation allows the system to relieve network congestion by reducing traffic during silent periods without significantly impacting user communication quality or reducing the number of accommodated users.
2Productivity
If priority levels are lowered for silent section packets, then resource allocation efficiency improves, but communication quality for non-critical users degrades
Solution Approach 1:
The patent implements dynamics by making priority levels adjustable based on operational conditions. During normal operations, all voice packets maintain standard priority levels. During emergencies, the system dynamically adjusts priority levels specifically for silent section packets while preserving normal priorities for voiced sections. This dynamic adjustment optimizes resource allocation during critical periods without permanently degrading communication quality.
3Stability of the object's composition
If congestion control is implemented during emergencies, then network stability is improved, but the number of accommodated users decreases
Solution Approach 1:
The patent applies parameter changes by modifying the priority level parameter specifically for silent section packets during emergency conditions. This selective parameter modification allows the system to improve network stability by reducing unnecessary traffic during silent periods while maintaining accommodation capacity for actual communication needs. The approach avoids blanket restrictions that would reduce user capacity.

AI summary
A wireless base station includes a state-of-emergency determiner, a silent section detector, a priority level controller, a resource allocation request detector, and a resource controller. The state-of-emergency determiner determines a state of emergency. In a case of the state of emergency, the silent section detector detects a silent section for a downlink voice packet. In the case of the state of emergency, the priority level controller lowers a transmission priority level of a packet in the silent section for the downlink voice packet. In the case of the state of emergency, the resource allocation request detector detects a request for allocation of an uplink radio resource to a silent section for an uplink voice packet. In the case of the state of emergency, the resource controller lowers a priority level for the allocation of the uplink radio resource to the silent section for the uplink voice packet.
