Cell Identifier Format Adaptation for Wireless Network Signaling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies in determining base station identifiers within global cell identifiers, particularly when dealing with varying numbers of base stations and cells, as existing methods require additional signaling bits to convey cell identifier formats, increasing overhead and decreasing efficiency.
Innovation Solution
The proposed solution associates the format of cell identifiers, including the length of base station identifiers, with area identifiers, allowing for different formats to accommodate various numbers of base stations and cells without additional signaling bits, by using a lookup table to determine the correct format based on the area identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional signaling bits are used to convey cell identifier formats, then the system can accommodate varying numbers of base stations and cells, but the signaling overhead increases and efficiency decreases
Solution Approach 1:
The area identifier is made to serve dual purposes: its traditional function of identifying a geographic area and an additional function of indicating the cell identifier format. By making the area identifier multi-functional, the patent eliminates the need for separate signaling bits to convey format information, thus reducing overhead while maintaining adaptability to different network configurations
Solution Approach 2:
The patent merges the area identifier and the cell identifier format indication into a single identifier structure. Instead of using separate fields for area identification and format specification, the solution combines these functions into one unified identifier that simultaneously provides both pieces of information, thereby reducing total signaling requirements
2Loss of information
If a fixed cell identifier format is used, then signaling overhead is reduced, but the system cannot efficiently accommodate varying numbers of base stations and cells in different areas
Solution Approach 1:
The patent introduces dynamic adaptability into the cell identifier system by allowing the identifier format to change based on the area identifier value. Different areas can dynamically use different format configurations (such as varying lengths for base station identifier and cell identifier portions) without requiring separate signaling, enabling the system to adapt to local network densities and configurations
Solution Approach 2:
The patent applies local quality by allowing different areas to have different cell identifier formats tailored to their specific needs. Each area can be configured with the appropriate identifier structure based on its number of base stations and cells, optimizing the use of identifier space locally while maintaining overall system consistency through the unified area identifier mechanism
