Carrier Frequency Prioritization for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack the ability to dynamically prioritize carrier frequencies based on the operational characteristics of individual wireless communication devices (WCDs), leading to suboptimal handover decisions and resource allocation.
Innovation Solution
A method and system where a base station broadcasts multiple sets of priority levels for carrier frequencies, each correlated with specific WCD operational characteristics, allowing WCDs to select and apply the appropriate prioritization based on their characteristics, enabling dynamic frequency selection for improved coverage and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of carrier frequency priority levels is broadcast for all WCDs, then the system is simple to implement, but it cannot optimize handover decisions for different device types with different operational characteristics
Solution Approach 1:
The patent segments the single set of priority levels into multiple sets, each correlated with specific WCD operational characteristics. The base station broadcasts multiple priority level sets (e.g., first set for characteristic X, second set for characteristic Y), allowing WCDs to select the appropriate set based on their characteristics. This segmentation enables differentiated optimization for different device types while maintaining a structured, manageable system architecture.
Solution Approach 2:
The patent applies local quality by assigning different priority level characteristics to different WCD operational characteristics. Each priority level set is tailored to specific device needs (e.g., voice-centric vs. data-centric devices), ensuring that each WCD receives prioritization optimized for its specific operational profile rather than a one-size-fits-all approach.
2Reliability
If carrier frequency priority levels are optimized for specific WCD operational characteristics, then handover decisions are improved, but the base station must broadcast and manage multiple sets of priority levels increasing message size and processing complexity
Solution Approach 1:
The patent implements preliminary action by having the base station pre-calculate and pre-organize multiple priority level sets correlated with different WCD operational characteristics before broadcasting. The system information message is prepared in advance with all necessary priority sets, allowing WCDs to immediately select and apply the appropriate set without requiring complex real-time calculations or additional signaling exchanges.
3Productivity
If multiple sets of priority levels are broadcast for different WCD operational characteristics, then resource allocation is optimized, but the system requires more complex selection logic in WCDs
Solution Approach 1:
The patent enables self-service by allowing each WCD to autonomously determine its own operational characteristic and select the corresponding priority level set from the broadcast options. The WCD independently evaluates its characteristics (e.g., voice-centric or data-centric) and autonomously applies the appropriate priority set without requiring complex network-controlled selection logic or extensive inter-device coordination.

AI summary
As disclosed, while a wireless communication device (WCD) is idling on a particular carrier frequency of a base station, the base station may receive a message broadcast by that base station, the message specifying multiple relative sets of priority levels defined for a set of carrier frequencies and correlating each of the multiple relative sets of priority levels with respective different WCD operational characteristics. In particular, the message may specify a first correlation of one relative set of priority levels with one WCD operational characteristic and includes a second correlation of a different relative set of priority levels with a different WCD operational characteristic. The WCD may select one of the relative sets of priority levels responsive to the WCD having a WCD operational characteristic that the message correlates with the selected relative set of priority levels. The WCD may then apply the selected relative set of priority levels.
