Location Record Extraction for Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern communication systems, wireless devices frequently change location, leading to the need for updated location information, which results in the creation of additional usage data records that often contain unchanged data fields, causing inefficiencies in the AAA system due to the transmission of large data files.
Innovation Solution
A method and system that receive a usage data record at an access node, create a location record with relevant location attributes when the AAA system does not require the full usage data record, and update these attributes as the device changes location, reducing data transmission by only sending necessary location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If updated usage data records are created whenever the wireless device changes location, then location information is kept current, but data transmission volume increases due to sending entire large usage data records even when only location fields changed
Solution Approach 1:
The patent extracts only the location attributes from the complete usage data record to create a separate location record. This allows the system to transmit minimal data (only location information) while maintaining accurate location tracking, resolving the contradiction between keeping location information current and reducing data transmission volume.
Solution Approach 2:
The usage data record is segmented into a location record containing only location attributes and the remaining usage data. This segmentation enables independent handling of location information, allowing the system to update and transmit location data separately from other usage data, thereby reducing overall data transmission volume while maintaining location accuracy.
2Reliability
If complete usage data records are transmitted to the AAA system for every location update, then all data is available for processing, but system efficiency decreases due to handling large redundant data files
Solution Approach 1:
The patent extracts location attributes from the complete usage data record to create a dedicated location record. This extraction allows the AAA system to process only the necessary location information without handling redundant usage data, improving processing efficiency while maintaining data reliability for location-related functions.
Solution Approach 2:
Instead of transmitting complete usage data records for every location update, the system transmits only the partial location record containing essential location attributes. This partial action approach maintains sufficient data reliability for location tracking while significantly improving system processing efficiency by avoiding redundant data transmission.
3Quantity of substance
If a separate location record is created with only location attributes, then data transmission is minimized, but additional processing steps are required to create and maintain the location record
Solution Approach 1:
The patent creates the location record structure in advance by extracting location attributes from the usage data record. This preliminary action establishes a ready-to-use location record format that simplifies subsequent updates and transmissions, reducing the complexity of processing procedures while maintaining minimal data transmission volume.
Solution Approach 2:
The location record is designed as a universal structure that can be populated from usage data records and used across multiple location updates. This multi-functional approach allows the same location record format to serve all location tracking needs, reducing processing complexity through standardization while maintaining minimal data transmission.

AI summary
A method for providing location information for a wireless device in a communication system is provided. The method comprises receiving a usage data record for the wireless device at an access node, and providing the usage data record to an authentication node. The method further comprises creating a location record from the usage data record when the authentication node determines that the communication system does not require the usage data record, populating the location record with one or more location attributes associated with the wireless device, and providing the location record to the authentication node.
