Dynamic Bandwidth Allocation Using User Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems do not effectively utilize user state information to optimize bandwidth allocation, leading to sub-optimal use of resources and potential disruption to users, as they do not consider the user's engagement or location in determining bandwidth allocation for streaming video content.
Innovation Solution
A communication device and network management entity system that uses sensor data to adjust bandwidth allocation based on user characteristics, such as heart rate or location, to enhance Quality of Experience (QoE) by prioritizing bandwidth according to user engagement and needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If bandwidth allocation is maintained at current levels without considering user state, then user QoE may be preserved in some cases, but bandwidth is wasted when users are not actively viewing content
Solution Approach 1:
The system dynamically adjusts bandwidth allocation based on real-time user state information from sensors. The network management entity receives sensor data indicating user characteristics (e.g., attentiveness, location, activity) and modifies bandwidth allocation accordingly, transitioning from static to dynamic resource management that adapts to changing user conditions
Solution Approach 2:
The system implements a feedback loop where sensor data about user state is continuously collected and transmitted to the network management entity. This feedback mechanism enables the system to monitor user engagement and adjust bandwidth allocation in response to actual user needs, preventing waste while maintaining quality of experience
2Loss of energy
If bandwidth is reduced without considering user state, then bandwidth efficiency improves, but user QoE deteriorates when users need high bandwidth
Solution Approach 1:
The system changes the parameter of bandwidth allocation based on user state parameters obtained from sensors. By monitoring user characteristics such as attentiveness, location, and activity level, the system adjusts bandwidth allocation parameters dynamically, ensuring high bandwidth is provided when users need it while reducing bandwidth when users are not actively engaging with content
3Productivity
If user state monitoring is implemented, then bandwidth allocation efficiency improves, but system complexity increases
Solution Approach 1:
The system introduces a network management entity as an intermediary that handles the complexity of processing sensor data and making bandwidth allocation decisions. This intermediary component receives sensor information from user devices, processes the data to determine user state, and adjusts bandwidth allocation accordingly, centralizing the complexity management function

AI summary
Provided is an apparatus and method for adjusting a bandwidth allocation for a traffic flow associated with a user as a function of a sensed characteristic of the user. A communication device has a sensor data receiver for receiving sensor data pertaining to a sensed characteristic of a user, and circuitry implementing an IRSCU (information representative of the sensed characteristic of the user) messenger configured for sending, to a network entity used for adjusting a bandwidth allocation for a traffic flow associated with the user, a message containing IRSCU. A network management entity, which receives the IRSCU, has circuitry implementing a bandwidth adjustor, which is configured for adjusting, based on the IRSCU, a bandwidth allocation for a traffic flow associated with the user. Accordingly, the bandwidth allocation for the traffic flow associated with the user is adjusted as a function of the sensed characteristic of the user.
