Call Downgrade Reason Indicator for Network Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunication networks, when a user equipment (UE) downgrades an enhanced call to an audio-only call, the network cannot determine whether the downgrade is due to a user's instruction or a problem with the network or the UE, making it difficult to identify and fix issues.
Innovation Solution
The UE transmits a downgrade reason indicator to the telecommunication network, specifying whether the downgrade is automatic or user-initiated, allowing the network to differentiate between user choices and service or equipment problems.

Engineering Contradiction Analysis
1Reliability
If the UE transmits a downgrade reason indicator to the telecommunication network, then the network can diagnose and address issues by distinguishing between user-driven and automatically triggered downgrades, but the device complexity increases due to additional signaling requirements
Solution Approach 1:
The patent introduces a downgrade reason indicator as an intermediary signaling element that mediates between the UE and the telecommunication network. This indicator acts as a mediator that conveys the reason for call downgrade (user-initiated vs. automatic) without requiring complex dialogue or additional communication rounds, thus improving diagnostic capability while keeping signaling overhead manageable
Solution Approach 2:
The downgrade reason indicator is prepared and transmitted in advance as part of the call downgrade signaling process. By including the reason indicator proactively during the downgrade event, the network receives diagnostic information beforehand, enabling faster issue identification and resolution without requiring additional follow-up signaling or complex post-event analysis

AI summary
A method of signaling a reason for a downgrade of an enhanced call to an audio-only call. User equipment (UE) can engage, via a telecommunication network, in an enhanced call including audio content and additional content. The UE can generate a downgrade message that requests a downgrade of the enhanced call to an audio-only call that includes the audio content without the additional content. The downgrade message can include a downgrade reason indicator identifying whether the UE is automatically downgrading the enhanced call or whether the UE is instead downgrading the enhanced call due to user instructions. The UE can send the downgrade message to the telecommunication network.
