Solution Overview

Problem

Current Customer Experience Management systems in cellular networks lack actionable data on mobile subscriber network experience, particularly precision information for geo-tagging and network health, limiting their ability to improve customer care and network fault resolution.

Innovation Solution

A system that generates mobile subscriber network experience indicators by receiving call trace logs, geo-tagging them with location information, aggregating records based on IMSI, identifying key performance indicators, and displaying network experience indicators through a graphical user interface, allowing for differentiation between network and subscriber-related service failures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If probe-based systems collect protocol flow data in the cellular network core, then data collection is simplified, but precision information for geo-tagging and network health cannot be captured

Engineering Contradiction:
Improvedata collection simplicityVSAvoidgeo-tagging precision
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent introduces a mediator component that bridges the network core and RAN elements. This intermediary collects detailed RAN measurements (including precise geo-location data) and forwards selected information to the network core, allowing probe-based systems to access high-precision geo-tagging information without directly interfacing with RAN hardware.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent adds a new dimensional layer to the data collection architecture by introducing a specialized data collection point at the RAN-core interface. This intermediate dimension enables simultaneous access to both the simplicity of core-based processing and the precision of RAN-level measurements, resolving the spatial contradiction in data collection locations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If probe-based systems collect protocol flow data in the cellular network core, then system complexity is reduced, but actionable network experience data is unavailable

Engineering Contradiction:
Improvesystem complexityVSAvoidactionable network experience data
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent extracts only the essential RAN-level measurements needed for network experience assessment (such as radio quality metrics and geo-location data) and transports them to the network core. This extraction approach maintains the simplicity of core-based processing while capturing the critical actionable information that would otherwise be lost.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by collecting comprehensive RAN measurements at the RAN level where they are generated, then selectively filtering and transporting only the most relevant data to the network core. This ensures that local measurement precision is preserved for actionable insights while avoiding the complexity of processing all raw RAN data centrally.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If detailed RAN measurements are collected at the radio access network level, then network experience data quality improves, but data processing complexity increases

Engineering Contradiction:
Improvenetwork experience data qualityVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent performs preliminary filtering, aggregation, and validation of RAN measurements at the point of collection before transmitting data to the network core. This preliminary processing reduces the volume and complexity of data requiring centralized processing while preserving the essential network experience information, thereby resolving the complexity contradiction.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system, method, and computer program product are provided for generating mobile subscriber network experience indicators based on geo-located events. In use, one or more call trace logs are received including protocol flow information between User Equipment and one or more network elements associated with a network. Additionally, one or more call detail records are generated utilizing the one or more call trace logs, each of the one or more call detail records including an associated international mobile subscriber identity (IMSI). Further, the one or more call detail records are geo-tagged with location information associated with the one or more call trace logs. In addition, the one or more geo-tagged call detail records are aggregated based on the international mobile subscriber identity associated with the one or more geo-tagged call detail records, such that a subscriber corresponding to the international mobile subscriber identity is associated with at least one of the aggregated geo-tagged call detail records. Furthermore, a plurality of key performance indicators are identified for the subscriber, utilizing the at least one aggregated geo-tagged call detail record associated with the subscriber. Moreover, a network experience indicator associated with the subscriber is generated utilizing one or more of the plurality of key performance indicators. Still yet, the network experience indicator associated with the subscriber is displayed utilizing a graphical user interface.
