Solution Overview

Problem

Wireless communication devices face difficulties in transitioning to newer network generations due to hardware and software incompatibilities, leading to issues with voice services, particularly VoLTE, even if they are hardware-capable, due to out-of-date software or incorrect settings.

Innovation Solution

A system and method that evaluates signaling information to determine voice communication capabilities by using a database to associate device identifiers and software versions with voice communication capabilities, enabling accurate assessment of a device's suitability for newer networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication devices use hardware capable of newer network generations, then hardware compatibility is improved, but software incompatibility prevents successful service delivery

Engineering Contradiction:
Improvehardware compatibilityVSAvoidservice delivery reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary evaluation of voice communication capabilities by analyzing signaling information (UA strings, device identifiers, software versions) before actual service deployment. This advance assessment identifies devices with hardware capability but software incompatibility, allowing operators to proactively notify customers about necessary updates or replacements, preventing service failures later

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary evaluation system that acts as a mediator between the device hardware capability and the network service delivery. This system uses signaling information analysis as an intermediate step to determine actual voice communication capability, bridging the gap between hardware potential and software reality

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If operators discontinue older network generations to reduce operational costs, then operational efficiency is improved, but service availability deteriorates for incompatible devices

Engineering Contradiction:
Improveoperational efficiencyVSAvoidservice availability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Before discontinuing older network generations, operators use this system to preliminarily identify which devices will be affected and cannot transition to newer networks. This allows operators to prepare customer notification campaigns and replacement programs in advance, ensuring continuous service availability during the transition period

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to operators about the actual voice communication capabilities of devices in their network. This feedback mechanism enables operators to make informed decisions about network generation discontinuation, targeting only those devices that can successfully transition while maintaining service availability for others

Inventive Principle:
Principle #23Feedback

3Reliability

If customers are required to install software updates to maintain service capability, then service compatibility is improved, but customer convenience deteriorates

Engineering Contradiction:
Improveservice compatibilityVSAvoidcustomer convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary identification of devices requiring software updates before service disruption occurs. By analyzing signaling information in advance, operators can notify customers proactively about needed updates, allowing customers to update at their convenience rather than experiencing sudden service failure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a cushioning mechanism by identifying at-risk devices in advance and providing customers with advance notice and guidance about necessary software updates. This prevents the harsh impact of sudden service discontinuation, cushioning the transition through proactive communication and customer support

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The disclosure pertains to a system for determining at least one voice communication capability of at least one wireless communication device configured to register in and connect to a core network through at least one radio access network using at least one radio access technology. The system may comprise a signalling information evaluation system configured to determine at least one of first signalling information and second signalling information for the wireless communication device depending on radio access technology used by the wireless communication device when registering or establishing a voice connection in the core network through the radio access network. The system may further comprise or have access to at least one database comprising the at least one voice communication capability associated with at least one of the first signalling information and the second signalling information. The system may be configured to determine the at least one voice communication capability from the at least one database based on at least one of the determined first signalling information and second signalling information. From the signalling information obtained for the wireless communication device upon registering and connecting through a radio access network, the database can be queried to obtain access to the voice communication capability to be determined.
