IMS Wireless Mute Tracking Through SIP BYE Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices fail to provide accurate information about network-related mute events, especially when users terminate sessions before the predetermined threshold, leading to incomplete data for the core network to identify and address the root causes of poor connectivity.
Innovation Solution
Mobile devices are configured to track mute-related information, such as RTP packet loss, and report it to the IMS stack, which includes this information in SIP BYE messages, enabling the core network to receive crowd-sourced data for pattern recognition and improvement.

Engineering Contradiction Analysis
1Extent of automation
If mobile devices automatically terminate sessions without user input when mute duration reaches a threshold, then autonomous termination is achieved, but mute-related information is not reported to the core network
Solution Approach 1:
The mobile device is configured to determine and store mute-related information (such as mute duration, packet loss rate, radio connection indicator) before session termination occurs. This preliminary data collection ensures that when the session is terminated—whether automatically or by user action—the information is already captured and can be reported to the core network via the SIP BYE message.
Solution Approach 2:
The system implements a feedback mechanism where mute-related information is continuously monitored and collected during the session, then fed back to the core network through the SIP BYE message. This feedback loop allows the core network to receive accurate information about mute events even when automatic termination occurs without user input.
2Ease of operation
If users terminate sessions before the predetermined threshold is reached, then user control is maintained, but the core network fails to obtain mute event information
Solution Approach 1:
The mobile device continuously determines and stores mute-related information during the session before termination occurs. This preliminary action ensures that regardless of when the session is terminated—whether by the user or automatically—the information is already captured and ready to be reported to the core network.
Solution Approach 2:
The mobile device autonomously collects and prepares mute-related information without requiring user intervention. The device serves itself by automatically determining, storing, and reporting the information through the SIP BYE message, ensuring that mute event data is captured even when users manually terminate sessions.
3Device complexity
If traditional mobile devices do not send mute-related information, then device complexity is reduced, but the core network lacks data for pattern recognition and root cause identification
Solution Approach 1:
The existing SIP BYE message mechanism, traditionally used only for session termination notification, is enhanced to also carry mute-related information. This multi-functionality allows the same message structure to serve dual purposes: terminating the session and reporting quality metrics, thereby minimizing additional device complexity while maximizing information collection.
Solution Approach 2:
The SIP BYE message is modified to include additional parameters (mute duration, packet loss rate, radio connection indicator) beyond the standard termination notification. This parameter expansion enables the message to convey rich mute event information without fundamentally changing the underlying protocol or significantly increasing device complexity.
4Loss of energy
If the core network does not receive crowd-sourced mute data, then network resource consumption is reduced, but the ability to identify and address root causes of poor connectivity is impaired
Solution Approach 1:
Mobile devices autonomously collect, store, and prepare mute-related information without requiring continuous network intervention. The devices self-service by gathering quality metrics locally and only transmitting this aggregated information to the core network when sessions terminate, thereby minimizing ongoing network resource consumption while ensuring reliable data collection for connectivity quality improvement.
