Wireless Resource Allocation Across Frequency Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, existing systems face challenges in efficiently allocating resources across multiple frequency bands to meet varying application requirements, leading to suboptimal service quality and resource utilization.
Innovation Solution
A wireless device establishes default channels with access nodes operating on different frequency bands, determines application requirements, and selects a dedicated channel based on these needs, optimizing resource allocation for services like voice and data by assigning channels with suitable quality of service parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless device establishes connections with multiple cells on different frequency bands, then service quality and resource utilization are improved, but system complexity and resource allocation difficulty increase
Solution Approach 1:
The patent segments the frequency band resources into multiple cells, each operating on different frequency bands. The wireless device establishes separate default control channels with each cell, allowing independent resource management and allocation on each frequency band, thereby improving overall resource utilization while maintaining manageable system complexity through structured division
Solution Approach 2:
The patent implements a universal resource allocation mechanism that operates across multiple frequency bands and cells. The same resource allocation principles and channel establishment procedures are applied universally across different frequency bands, enabling efficient resource utilization without proportionally increasing system complexity through standardized multi-functional approaches
2Reliability
If default control channels are established on multiple cells before determining application requirements, then network resource preparation is improved, but resource allocation time and signaling overhead increase
Solution Approach 1:
The patent applies preliminary action by establishing default control channels on multiple cells before application requirements are determined. This allows network resources to be prepared in advance on multiple frequency bands, ensuring reliable resource availability. The preliminary channel establishment enables subsequent rapid resource allocation once application requirements are known, reducing overall allocation time despite the initial setup
Solution Approach 2:
The patent implements feedback mechanisms where application requirements are communicated back to the network after preliminary channel establishment. This feedback allows the network to optimize resource allocation on the already-established channels, adjusting resource distribution based on actual application needs while leveraging the head-start provided by preliminary channel setup

AI summary
Systems and methods are described for allocating resources between frequency bands in a wireless network. A wireless device may establish multiple default channels for wireless communication with two or more cells associated with different frequency bands. The default channels on each of the cells may be used to communicate control signals between the two or more cells and the wireless device. Application requirements may be determined and each of the cells may assign a dedicated channel for service, and one of the dedicated channels may be selected to provide service to the wireless device based on the determined application requirements.
