Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for wireless data traffic due to smartphones has led to decreased average revenue per user, prompting network operators to enhance cellular network efficiency and use less expensive data transport mechanisms like Wi-Fi, but this introduces jitter issues that affect service quality, particularly for jitter-sensitive services like voice over Wi-Fi, which can result in poor user experiences.
Innovation Solution
Implementing a system that allows mobile devices to self-optimizing technology selection thresholds by determining acceptable signal strength for connecting to access points, using jitter measurements to assess network paths and adjust signal strength thresholds, thereby preventing the use of poor Wi-Fi for jitter-sensitive services in a battery-efficient manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile devices use less expensive wireless data transport mechanisms like Wi-Fi to reduce costs and increase network efficiency, then cost and network efficiency improve, but jitter increases which deteriorates service quality for jitter-sensitive services
Solution Approach 1:
The system continuously measures jitter performance on Wi-Fi network paths and uses this feedback to dynamically adjust technology selection thresholds. The mobile device monitors jitter metrics and adjusts its decision-making for selecting between cellular and Wi-Fi networks based on observed performance, creating a closed-loop control system that adapts to changing network conditions.
Solution Approach 2:
The invention changes the parameter of technology selection thresholds based on measured jitter performance. Instead of using fixed signal strength thresholds, the system adjusts thresholds dynamically according to observed jitter characteristics of different network paths, allowing optimal selection between cellular and Wi-Fi networks for jitter-sensitive services.
2Measurement precision
If mobile devices perform repeated jitter measurements to assess network paths accurately, then measurement precision improves, but energy consumption increases which reduces battery life
Solution Approach 1:
The system performs jitter measurements in advance during network selection and connection establishment phases. By measuring jitter beforehand and establishing performance baselines, the device can make informed network selection decisions without requiring continuous repeated measurements, thereby reducing overall energy consumption while maintaining accurate network path assessment.
Solution Approach 2:
The invention applies partial action by performing jitter measurements selectively rather than continuously. The system measures jitter at key decision points (network selection, threshold adjustment) and uses these partial measurements to inform subsequent network usage decisions, achieving sufficient measurement precision without the energy cost of continuous monitoring.
3Ease of operation
If mobile devices use default signal strength thresholds for Wi-Fi connection selection, then ease of operation improves, but service reliability deteriorates because default thresholds cannot account for jitter-sensitive services
Solution Approach 1:
The system transitions from static default thresholds to dynamic adaptive thresholds. The technology selection thresholds are automatically adjusted based on measured jitter performance, allowing the system to adapt to different network conditions and service requirements. This maintains ease of operation through automatic adjustment while improving reliability for jitter-sensitive services.
Solution Approach 2:
The mobile device performs self-optimization by automatically measuring jitter, analyzing performance, and adjusting its own technology selection thresholds without user intervention. The system serves itself by autonomously adapting to network conditions and optimizing its network selection behavior for different service types.

AI summary
Techniques that facilitate mobile device self-optimizing technology selection thresholds for a wireless communication system are provided. In one example, a method comprises: generating, at a first time, first information in a repository of information specific to and stored at the apparatus, wherein the first information comprises an identifier for a first access point device and a determined acceptable signal strength usable to obtain an acceptable jitter value between the apparatus and the first access point device; and initiating a defined type of communication via the first access point device, at a second time, based on a first determination that a detected signal strength at a third time satisfies a defined condition relative to the acceptable signal strength, wherein the second time is after the first time and wherein the third time is between the first time and the second time.
