Dynamic Channel Bandwidth Allocation for Radio Access Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static channel bandwidth allocation methods between radio access technologies at a cell site are inefficient, as they do not adapt to changing radio frequency conditions, such as varying numbers of user devices and guaranteed bit rate requirements, leading to suboptimal user experience and network resource allocation.
Innovation Solution
Implement a dynamic method to reallocate channel bandwidth between radio access technologies, such as 4G and 5G, based on monitored radio frequency conditions, including the number of user devices and those with guaranteed bit rates, to adjust bandwidth allocation in real-time, ensuring better throughput and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static channel bandwidth allocation is used between radio access technologies, then device complexity is reduced and ease of operation is improved, but adaptability to changing radio frequency conditions deteriorates and network efficiency is reduced
Solution Approach 1:
The patent implements dynamic bandwidth allocation by enabling the system to adjust channel bandwidth allocation in real-time based on monitored radio frequency conditions, user device quantities, and guaranteed bit rate requirements. This transforms the static allocation mechanism into a dynamic one that automatically adapts to changing network conditions, resolving the contradiction between adaptability and system complexity.
Solution Approach 2:
The system continuously monitors radio frequency conditions, user device quantities, and service requirements, then uses this feedback information to adjust bandwidth allocation decisions. This closed-loop feedback mechanism enables adaptive bandwidth allocation while maintaining manageable system complexity through automated decision-making based on predefined criteria and real-time network state.
2Productivity
If static channel bandwidth allocation is used, then system simplicity is maintained, but network resource allocation efficiency deteriorates when user device quantities vary
Solution Approach 1:
The system dynamically adjusts channel bandwidth allocation based on real-time monitoring of user device quantities and service requirements. When the quantity of user devices using a particular radio access technology exceeds a threshold or when guaranteed bit rate requirements change, the system automatically reallocates bandwidth to optimize network resource allocation efficiency, moving from static to dynamic resource management.
Solution Approach 2:
The patent changes the bandwidth allocation parameters dynamically based on network conditions. By adjusting channel bandwidth as a variable parameter rather than a fixed value, the system optimizes resource allocation efficiency in response to changing user device quantities and service requirements, allowing bandwidth to be increased or decreased for different radio access technologies as needed.
3Ease of operation
If bandwidth is allocated based on current user device quantities, then user experience and throughput are improved, but the complexity of monitoring and adjusting bandwidth increases
Solution Approach 1:
The system implements continuous monitoring of user device quantities, radio frequency conditions, and service requirements, using this feedback to automatically adjust bandwidth allocation. This feedback-driven approach improves user experience by ensuring adequate bandwidth for active users while managing system complexity through automated decision-making based on predefined thresholds and criteria.
Solution Approach 2:
The bandwidth allocation system operates autonomously by monitoring its own network state and automatically adjusting allocations based on detected conditions. The system serves itself by making real-time bandwidth adjustment decisions without requiring manual intervention, thereby improving user experience while keeping operational complexity manageable through self-management.

AI summary
Methods and systems are provided for dynamically modifying bandwidth allocation corresponding to a first radio access technology and a second radio access technology. A current allocation of channel bandwidth corresponding to the first radio access technology and the second radio access technology is determined. One or more radio frequency conditions associated with a base station may be monitored, which could include loading at a particular cell site or sector and/or user devices that have a guaranteed bit rate. Based on monitoring of the radio frequency conditions, the current allocation of the channel bandwidth corresponding to the first radio access technology and the second radio access technology is dynamically modified to a different allocation of channel bandwidth corresponding to the first radio access technology and the second radio access technology.
