Dual Network Wake-Up Period Rescheduling via Preference Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concurrent operation of Legacy WLAN and Wi-Fi Aware networks faces challenges in dual network scheduling, particularly when a single MAC/PHY is used, leading to issues with wake-up periods overlapping or being too far apart, causing inefficiencies and increased power consumption.
Innovation Solution
A communicating method where the wake-up period of the communication device for the first network is rescheduled by adjusting preference parameters to align or separate from the wake-up period of the second network, allowing the device to act as a master and manage its own wake-up times effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single MAC/PHY is used to provide dual network connection for cost saving, then device complexity and cost are reduced, but dual network scheduling efficiency deteriorates due to wake-up period conflicts
Solution Approach 1:
The patent implements dynamic wake-up period adjustment by allowing the device to switch between different wake-up schedules based on network conditions. The device can dynamically change its wake-up timing to align with either Legacy WLAN or Wi-Fi Aware networks, optimizing scheduling efficiency while using a single MAC/PHY interface.
Solution Approach 2:
The patent changes the wake-up period parameter dynamically to resolve scheduling conflicts. By adjusting the wake-up period duration and timing based on which network is active, the system maintains high scheduling efficiency despite using a single MAC/PHY interface for both networks.
2Use of energy by moving object
If wake-up periods of two networks are aligned to reduce power consumption, then energy efficiency is improved, but network performance deteriorates due to potential conflicts and interference
Solution Approach 1:
The patent introduces a network manager as an intermediary that coordinates wake-up periods between Legacy WLAN and Wi-Fi Aware networks. The manager ensures that wake-up periods are aligned only when appropriate, preventing conflicts while maintaining power efficiency. It acts as a mediator that balances energy savings with network performance requirements.
3Reliability
If wake-up periods are separated to avoid conflicts, then network reliability is improved, but power consumption increases due to more frequent wake-ups
Solution Approach 1:
The patent implements periodic wake-up schedules that are optimized for each network type. Instead of continuous monitoring, the device wakes up at predetermined intervals specific to each network's requirements. This periodic action maintains network reliability while minimizing power consumption by avoiding unnecessary wake-ups.
4Adaptability or versatility
If preference parameters are adjusted to make the device a master to reschedule wake-up periods, then scheduling flexibility is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service scheduling where the device automatically adjusts its own wake-up periods based on network conditions and preference parameters. The device acts as its own master, making scheduling decisions autonomously without requiring complex external coordination, thus achieving flexibility while managing complexity through self-management.

AI summary
A communicating method of a communication device for connecting to a first network and a second network includes: when a rescheduling condition is reached, rescheduling a wake up period of the communication device for the first network at least according to a wake up period of the communication device for the second network; wherein the wake up period of the communication device for the first network is rescheduled by making the communication device a master device in the first network through adjusting a preference parameter of the first network.
