Dual-Path Communication Method for Stable Multi-Network Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods using frequency hopping spread spectrum technologies, such as IEEE 802.15.1, face instability and unintended communication failures when integrating multiple star-type networks, leading to excessive load and complexity in scatternets, which hinders applications like gaming across networks.
Innovation Solution
A communication method that integrates multiple star-type networks into a single star-type network by using dual communication paths, where one information processing apparatus acts as a master and others as slaves, allowing for role determination and adjustment to stabilize communication without constructing a scatternet, using a first communication path for initial setup and a second path for high-speed communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple star-type networks are integrated using frequency hopping spread spectrum technology, then communication range and connectivity are improved, but communication stability deteriorates due to unintended failures and excessive load
Solution Approach 1:
The patent segments the integrated network into two distinct communication paths: a first communication path for setup and control, and a second communication path for high-speed data transmission. This segmentation isolates the stability-critical setup processes from the high-performance data transfer, preventing interference between them and reducing unintended failures in multi-network integration.
Solution Approach 2:
The patent introduces a master apparatus as an intermediary that coordinates communication between slave apparatuses from different star-type networks. The master apparatus manages frequency hopping patterns and mediates data transmission, distributing the integration load and preventing excessive burden on individual apparatuses, thereby maintaining communication stability.
2Adaptability or versatility
If a scatternet structure is constructed to enable communication across networks, then connectivity between different networks is improved, but device complexity increases leading to excessive load and processing overhead
Solution Approach 1:
The patent divides the communication function into two separate paths: the first communication path handles network setup, authentication, and control functions, while the second communication path is dedicated to high-speed data transmission. This segmentation simplifies the overall process by allowing each path to be optimized independently, reducing the complexity burden that would otherwise accumulate in a unified scatternet structure.
Solution Approach 2:
The patent adds a dimensional distinction by creating parallel communication channels (first path and second path) instead of relying on a single complex scatternet dimension. This dimensional change allows the system to achieve cross-network connectivity through coordinated use of multiple simpler paths rather than one highly complex path, thereby reducing device complexity.
3Use of energy by moving object
If frequency hopping spread spectrum is used for wireless communication, then power consumption is reduced, but communication stability worsens when integrating multiple networks due to synchronization issues
Solution Approach 1:
The patent segments frequency hopping synchronization into two phases: initial synchronization established through the first communication path, and ongoing data transmission through the second communication path. This segmentation allows the power-efficient frequency hopping to be maintained while ensuring stability through dedicated setup procedures that establish robust synchronization before data transfer begins.
Solution Approach 2:
The patent performs preliminary synchronization and setup actions through the first communication path before initiating high-speed data transmission on the second communication path. This preliminary action ensures that frequency hopping patterns are properly aligned and synchronized across networks before data transfer, preventing stability issues while maintaining the power efficiency of frequency hopping spread spectrum.
