Situation-Related Communication Prioritization in Network Overloads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication networks face overload during emergency situations, leading to prioritization challenges where important communications related to the situation are hindered by non-prioritized, unimportant messages, resulting in reduced bandwidth for critical information.
Innovation Solution
A system comprising an anomaly detector, situation classifier, and situation filter that identifies overloads and classifies communications based on their relevance to the situation, prioritizing important messages and temporarily storing non-prioritized ones to maintain network bandwidth for critical communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all incoming communications are transmitted during overload, then communication completeness is maintained, but network bandwidth is insufficient and critical communications are delayed
Solution Approach 1:
The system segments communications into two distinct categories: prioritized communications (situation-related) and non-prioritized communications (non-situation-related). This segmentation allows the network to handle different types of traffic differently during overload conditions, ensuring that critical communications are transmitted promptly while non-critical communications are temporarily held in a repository.
Solution Approach 2:
The system applies different transmission qualities to different communications based on their relevance to the situation. Prioritized communications receive high-quality treatment with immediate transmission, while non-prioritized communications receive lower-quality treatment by being retained in a repository. This local quality differentiation resolves the contradiction by ensuring critical communications maintain high speed while overall communication completeness is preserved.
2Quantity of substance
If non-prioritized communications are transmitted during overload, then communication volume is maintained, but network congestion increases and bandwidth for critical information is reduced
Solution Approach 1:
The system extracts non-prioritized communications from the main transmission stream during overload conditions and places them in a separate repository. This extraction removes the harmful element (non-critical traffic) that is causing network congestion, allowing bandwidth to be reallocated to prioritized communications while still preserving the extracted communications for later transmission when capacity is available.
Solution Approach 2:
The system temporarily discards non-prioritized communications by holding them in a repository during overload conditions, rather than transmitting them immediately. These communications are not permanently discarded but are recovered for later transmission when network capacity becomes available. This approach maintains bandwidth efficiency for critical communications while preserving the option to transmit non-critical communications when possible.
3Productivity
If prioritization filtering is applied during overload, then bandwidth for critical communications is maintained, but system complexity increases due to content analysis requirements
Solution Approach 1:
The system performs preliminary classification of communications as situation-related or non-situation-related using the situation classifier before the overload condition fully impacts network capacity. This preliminary action allows the system to pre-identify prioritized communications that need immediate transmission, reducing the complexity of real-time decision-making during overload conditions while maintaining effective bandwidth utilization.
Solution Approach 2:
The situation classifier acts as an intermediary component that simplifies the prioritization process by automatically analyzing communication content and categorizing messages based on their relevance to the situation. This intermediary layer handles the complex content analysis task, allowing the rest of the system to operate with simpler logic while still achieving effective prioritization and maintaining bandwidth utilization.
4Ease of operation
If all communications are processed equally, then system simplicity is maintained, but critical communications are hindered by non-prioritized messages
Solution Approach 1:
The system dynamically adjusts its operation based on network conditions. During normal conditions, it operates in a simple mode treating all communications equally. During overload conditions, it dynamically switches to a prioritized mode where the situation classifier activates and differentiates between prioritized and non-prioritized communications. This dynamic behavior maintains system simplicity during normal operation while ensuring communication priority reliability during critical overload situations.

AI summary
A method of prioritizing communication in networks on a situation-related basis includes comparing a quantity of incoming communications to a predetermined threshold to determine whether an overload is occurring. The method further includes analyzing content of incoming communications, in response to determining that an overload is occurring, to determine whether the overload is related to a particular situation. The method further includes grouping incoming communications, in response to determining that the overload is related to the particular situation, into prioritized communications and non-prioritized communications. The method further includes transmitting the prioritized communications. The method further includes retaining, without transmitting, the non-prioritized communications in a repository so long as the overload is occurring.
