Abstract:
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.
