Wireless Communication Prioritization via Sensor Capture Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network congestion during emergency incidents in large buildings hinders reliable communication of evacuation routes to individuals, particularly those unfamiliar with the area, as existing portable communication systems struggle to prioritize and manage communication effectively.
Innovation Solution
A system and method that utilize sensors to capture over-the-air identifiers of portable communication devices, determine familiarity levels based on capture frequency and last capture time, and prioritize wireless communication by assigning quality of service to ensure efficient communication channel management during congestion periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network communication is provided to all portable communication devices during an emergency incident, then all individuals can receive evacuation information, but network congestion occurs and communication reliability deteriorates
Solution Approach 1:
The patent applies local quality by assigning different communication priorities to different portable communication devices based on their location and user familiarity level. Sensors capture over-the-air identifiers and determine capture parameters (such as number of times captured and last capture time) to classify devices into different priority groups. This creates non-uniform communication quality across the network, where unfamiliar users in critical areas receive higher priority communication channels, while familiar users receive standard service, thereby resolving the contradiction between serving all users and preventing congestion.
2Reliability
If communication priority is assigned based on user familiarity, then unfamiliar users receive critical information first, but system complexity increases due to sensor integration and capture parameter analysis
Solution Approach 1:
The patent applies universality by making the sensor system multi-functional. The same sensors that capture over-the-air identifiers are also used to determine capture parameters and indirectly assess user familiarity levels. This single sensor system performs multiple functions: device detection, user classification, and priority determination, thereby reducing the need for separate complex systems and minimizing overall system complexity while achieving reliable evacuation information delivery.
3Productivity
If quality of service is assigned based on capture parameters, then communication channel efficiency improves, but loss of information occurs due to potential inaccuracies in familiarity determination
Solution Approach 1:
The patent applies feedback by continuously monitoring capture parameters (number of times the over-the-air identifier is captured and last capture time) and using this information to dynamically adjust quality of service assignments. The system feedback loop allows for ongoing refinement of familiarity determination, where communication patterns themselves provide information about user behavior and familiarity, thereby improving accuracy over time and reducing information loss while maintaining high communication channel efficiency.

AI summary
A system and method for prioritizing a wireless communication to a portable communication device (102). In one example, a sensor (121) includes an electronic processor configured to capture an over-the-air identifier (404_1) of a portable communication device (102), determine a capture parameter based on at least one of a count of a number of times of capturing the over-the-air identifier and a last time of capturing the over-the-air identifier of the portable communication device (102), assign a priority level (414_1) to the portable communication device (102) based on the capture parameter, and prioritize the wireless communication between the sensor and the portable communication device (102) based on the priority level (414_1) assigned to the portable communication device (102).
