WLAN Relay Bandwidth Allocation for Hotspot Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The hotspot function in electronic devices reduces available bandwidth for both the host device and client devices, and existing methods cannot guarantee data usage and data rates.
Innovation Solution
An electronic device with a processor that establishes cellular and WLAN connections, checks policy information to determine bandwidth allocation, and blocks additional WLAN relay connections when a designated number of external devices is reached, ensuring prioritization and efficient data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hotspot function is enabled to allow external devices to access the network via cellular communication, then external devices can connect to the network, but the available bandwidth for both the host device and client devices is reduced
Solution Approach 1:
The system dynamically changes bandwidth allocation parameters based on connection status. When external devices connect via hotspot, the host device adjusts the bandwidth parameters for different devices to ensure fair distribution and maintain acceptable performance for all users
Solution Approach 2:
The bandwidth allocation is made dynamic rather than static. The system continuously monitors connection status and adjusts bandwidth distribution in real-time based on the number of connected devices and their data usage patterns, allowing the system to adapt to changing network conditions
2Adaptability or versatility
If multiple external devices are allowed to connect via WLAN relay function, then network coverage is extended, but data usage and data rates cannot be guaranteed
Solution Approach 1:
The host device implements feedback mechanisms to monitor data usage of connected external devices. Based on this feedback, the system adjusts bandwidth allocation dynamically, ensuring that data rate guarantees are maintained even as the number of connected devices varies
Solution Approach 2:
The system performs preliminary bandwidth allocation before external devices begin heavy data transmission. By pre-allocating bandwidth based on expected usage patterns and device priorities, the system ensures that data rate guarantees are in place before actual data flows occur
