Access Probe Power Optimization for Wireless Connection Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems experience delays in establishing wireless connections due to the need for multiple access probes sent at increasing power levels, which can degrade system performance, especially in scenarios where initial probes are unsuccessful.
Innovation Solution
Determine a first access probe power level based on the power levels and locations of successful access probes from existing wireless devices and provide this level to new devices, enabling them to send a successful access probe with reduced delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple access probes are sent at increasing power levels, then the access probe power level is sufficient to reach the access node, but the call setup duration increases
Solution Approach 1:
The system performs preliminary actions by having existing wireless devices report their access probe power levels and locations to the access node before new devices attempt access. The access node processes this information in advance to determine optimal power levels for new devices, eliminating the need for new devices to start with low power levels and progressively increase them through multiple attempts.
Solution Approach 2:
The system implements feedback by collecting information from existing wireless devices about their successful access probe power levels and using this feedback to determine optimal power levels for new devices. The access node receives reports from existing devices and uses this feedback to calculate and provide recommended power levels to incoming devices, ensuring higher success rates on first attempts.
2Reliability
If access probe power levels are increased, then the access probe can be received more reliably, but the energy consumption increases
Solution Approach 1:
The system changes the parameter of access probe power level from a fixed or progressive increase pattern to a dynamically optimized value based on environmental conditions. By analyzing the power levels used by existing devices at different locations, the system determines the specific power level parameter that achieves reliable reception while minimizing energy consumption, rather than using a blanket high power level or progressive escalation.
Solution Approach 2:
The system applies local quality by determining access probe power levels based on location-specific conditions. Each wireless device receives a customized power level recommendation based on its specific location relative to the access node and the reported characteristics of existing devices in that area, rather than using a uniform power level for all devices.
3Productivity
If the access node collects and processes wireless device information, then the access probe power level can be optimized, but the device complexity increases
Solution Approach 1:
The system segments the complexity by dividing the information collection and processing tasks between multiple components: existing wireless devices report their parameters, the access node collects and processes this information, and then provides recommendations to new devices. This segmentation distributes the computational burden and simplifies the overall system architecture compared to a centralized complex processing system.

AI summary
Wireless device information comprising a power level of a successful access probe sent by wireless devices to an access node and a location of each of the wireless devices relative to the access node is acquired. Based on the wireless device information, a first access probe power level is determined. The determined first access probe power level is provided to a new wireless device and an access probe is received from the new wireless device using the first access probe power level.
