Wireless Device Coverage Area Identifier Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in managing diverse coverage area identifiers from different base station vendors, leading to difficulties in extracting essential attributes for network analysis and service optimization.
Innovation Solution
A method where wireless communication devices (WCDs) determine the vendor group of the base station by receiving system and network identifiers, select appropriate parsing techniques using mapping data, and extract attributes from coverage area identifiers to report to service providers, enabling effective network monitoring and optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base stations from different vendors use diverse coverage area identifier formats, then each vendor can optimize for their equipment, but WCDs cannot uniformly parse and extract attributes from these identifiers
Solution Approach 1:
The patent changes the parameter of identifier format by introducing a standardized structure that all base stations must follow, regardless of vendor. This standardization allows WCDs to uniformly parse identifiers using consistent rules for extracting attributes like base station ID, cell ID, and sector ID, resolving the contradiction between vendor flexibility and parsing ease
Solution Approach 2:
The patent creates a universal coverage area identifier format that serves all vendors and all WCDs equally. The standardized structure enables any WCD to extract attributes from any base station's identifier using the same methodology, achieving universality across the heterogeneous network environment
2Adaptability or versatility
If WCDs store multiple parsing techniques for different vendor groups, then they can handle diverse identifier formats, but device complexity increases
Solution Approach 1:
The patent changes the approach from storing multiple parsing algorithms to storing a single standardized parsing rule set. By defining a uniform identifier structure, the system eliminates the need for WCDs to maintain multiple vendor-specific parsing techniques, reducing device complexity while maintaining adaptability
Solution Approach 2:
Instead of having WCDs adapt to multiple vendor formats through multiple parsing techniques, the patent inverts the approach by having all base stations conform to a single standardized format. This reversal simplifies the WCD's task to using one universal parsing method regardless of vendor
3Measurement precision
If service providers receive detailed network properties from WCDs, then network analysis quality improves, but data transmission and processing overhead increases
Solution Approach 1:
The patent extracts only the essential attributes from coverage area identifiers (base station ID, cell ID, sector ID) that are necessary for network analysis. By selecting and transmitting only these critical pieces of information rather than complete identifier data, the system maintains measurement precision while reducing data transmission overhead and energy consumption

AI summary
Disclosed herein is a method and system for parsing a coverage area identifier. An example method is operable in a wireless communication system having a base station and a wireless communication device (WCD), the base station radiating to define multiple coverage areas in which the WCD can operate. The method involves: the WCD operating within one of the multiple coverage areas; the WCD receiving from the base station a coverage area identifier of the coverage area in which the WCD operated; the WCD determining a group to which the base station belongs; the WCD using the determined group as a basis to select a parsing technique from multiple parsing techniques; and the WCD using the selected parsing technique to parse the received coverage area identifier so as to extract from the received coverage area identifier one or more attributes of the coverage area in which the WCD operated.
