Dynamic Bandwidth Allocation in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in providing quality-of-service and subscription level enforcement due to the mobility of subscribers and architectural differences from wired networks, leading to inadequate service for residential users and revenue loss for service providers.
Innovation Solution
Implementing a dynamic quality-of-service adjustment system in wireless networks based on location, time of day, and other factors, which modifies bandwidth provisioned, priority assignments, and network response times, allowing for differentiated service levels based on subscriber contracts and usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless networks provide uniform high bandwidth to all subscribers regardless of location or time, then service quality is improved, but service provider revenue is reduced due to inability to enforce subscription levels
Solution Approach 1:
The system dynamically adjusts bandwidth allocation based on real-time location detection and time-of-day parameters. The network transitions from static uniform bandwidth distribution to dynamic differentiated distribution, allowing service levels to change according to subscriber location and time, thereby enabling both quality of service enforcement and revenue optimization
Solution Approach 2:
The patent implements location-dependent service quality by detecting subscriber geographic position and applying different bandwidth profiles for different locations. Residential subscribers receive higher bandwidth at registered home locations while receiving limited bandwidth at other locations such as workplaces, creating localized quality differentiation that preserves revenue models
2Loss of energy
If wireless networks enforce location-based service levels, then service provider revenue is optimized, but service quality becomes inconsistent for mobile subscribers
Solution Approach 1:
The system performs preliminary registration of subscriber home locations and service preferences before actual service delivery. By pre-configuring location profiles and bandwidth allocations, the network can quickly enforce appropriate service levels when subscribers connect, ensuring both revenue optimization and consistent quality expectations are met without interruption
Solution Approach 2:
The patent implements continuous location monitoring and feedback loops that track subscriber movement and automatically adjust bandwidth allocation. When a subscriber moves between locations, the system detects the change and reconfigures service parameters in real-time, maintaining consistent quality of service enforcement while optimizing revenue based on current location and time
3Adaptability or versatility
If bandwidth is allocated based on multiple parameters (location, time, activity), then service differentiation is improved, but network complexity increases
Solution Approach 1:
The patent segments the service differentiation function into distinct modular components: location detection module, time-of-day detection module, activity type identification module, and bandwidth allocation module. Each component handles a specific parameter independently, allowing the system to achieve high service differentiation while managing complexity through functional segmentation and independent module operation

AI summary
Systems and methods are described for allocating bandwidth in a wireless network. Entry of subscriber equipment into a wireless network is detected at a base station which typically provides information used to determine geographic location of the subscriber equipment. Based on the determined location, a level of service is selected from a plurality of service levels available to a subscriber and provided. Location can be determined based on information provided by the subscriber equipment, provided by a global positioning system and/or provided by a user of the subscriber equipment. Location of the subscriber equipment can be identified with an activity of a user of the subscriber equipment, including business and non-commercial activity. Selection of the level of service may be further based upon time of day, day of week or upon a date and time of provision of the level of service.
