Bluetooth Data Forwarding Bandwidth Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth technologies are limited in their ability to efficiently forward data to multiple audio playback devices, particularly in scenarios where stereo audio transmission is required, as they typically support only a single data output connection, leading to inefficiencies in bandwidth allocation and potential interruptions in playback.
Innovation Solution
A method and apparatus that dynamically allocate Bluetooth communication bandwidth based on data volume thresholds, allowing for efficient data forwarding by designating a master device to receive and forward source data, prioritizing bandwidth allocation according to the volume of cached or to-be-forwarded data, ensuring stable and continuous playback across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single Bluetooth connection is used for audio transmission, then the connection is simple and stable, but the system cannot transmit data to multiple audio playback devices simultaneously
Solution Approach 1:
The patent introduces a forwarding device as an intermediary between the data output device and multiple audio playback devices. This forwarding device receives data from the data output device via Bluetooth and forwards it to multiple slave devices, enabling multi-device connectivity without requiring the data output device to maintain multiple direct connections. The intermediary approach resolves the contradiction by extending versatility while managing complexity through a dedicated forwarding node.
2Reliability
If bandwidth is allocated equally to all devices, then the allocation is simple, but playback interruptions occur when data volume is insufficient
Solution Approach 1:
The patent implements dynamic bandwidth allocation based on real-time data volume conditions. When data volume is sufficient, more bandwidth is allocated to forwarding operations; when data volume is insufficient, bandwidth is reallocated to receive operations to ensure playback continuity. This dynamic adjustment mechanism resolves the contradiction by prioritizing reliability through adaptive control, accepting increased complexity in the bandwidth management logic.
Solution Approach 2:
The system changes the bandwidth allocation parameter based on data volume thresholds. By monitoring data volume and adjusting bandwidth distribution accordingly, the system ensures that playback interruptions are prevented when data is insufficient, while optimizing transmission efficiency when data is abundant. This parameter-based control resolves the reliability-complexity contradiction through threshold-driven adaptive allocation.
3Productivity
If data is forwarded continuously, then transmission efficiency is high, but bandwidth is wasted when cached data is sufficient
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors cached data volume and adjusts forwarding behavior accordingly. When cached data is sufficient, the system reduces or pauses forwarding operations, avoiding bandwidth waste. When cached data becomes insufficient, the system resumes forwarding to maintain playback. This feedback-based control resolves the contradiction between transmission efficiency and energy waste by continuously adapting forwarding intensity to actual data needs.
Data Source
AI summary
A method for forwarding Bluetooth data, an electronic device, a Bluetooth device, and a Bluetooth system are disclosed. The method includes: in a Bluetooth communication process, receiving source data from a data output device as cached data, and forwarding the source data; and preferentially allocating a Bluetooth communication bandwidth to receive the source data if a data volume of the cached data is less than a first predetermined threshold; or preferentially allocating a Bluetooth communication bandwidth to forward the source data if a data volume of to-be-forwarded source data is greater than a second predetermined threshold.
