Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Internet telecommunications systems face issues with preconfigured maximum bitrate (MBR) limitations, leading to packet loss and degraded user experiences when bitrate exceeds the set limits, requiring cumbersome reconfiguration and resulting in muting and one-way communication.
Innovation Solution
A method and platform for dynamically adapting the MBR of IP Multimedia Subsystem (IMS)/Rich Communication Services (RCS) applications by receiving signals from client servers, establishing bearer channels, determining codec bitrates, and adjusting MBR to prevent packet loss and ensure compliance with configured bitrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a preconfigured maximum bitrate (MBR) is set for Internet telecommunications, then network resource management and quality of service are improved, but packet loss and muting occur when the actual bitrate exceeds the preconfigured limit
Solution Approach 1:
The patent implements dynamic MBR adjustment based on actual codec bitrate requirements. The system continuously monitors the bitrate used by the codec and automatically modifies the MBR configuration to match the actual transmission needs, preventing packet loss while maintaining network control. This dynamic adaptation resolves the contradiction by making the MBR flexible rather than fixed.
Solution Approach 2:
The system establishes a feedback mechanism where the actual bitrate used by the codec is monitored and fed back to the MBR configuration system. Based on this feedback, the MBR is automatically adjusted to accommodate the actual transmission requirements, ensuring that packet loss is prevented while maintaining network resource management effectiveness.
2Productivity
If the MBR is strictly enforced at the packet gateway, then network resource allocation is optimized, but user experience deteriorates due to muting and one-way communication
Solution Approach 1:
The patent applies preliminary action by pre-configuring the MBR based on the selected codec's expected bitrate requirements before communication begins. The system determines the appropriate MBR in advance based on the codec type and adjusts it proactively, preventing packet loss before it occurs rather than reacting after packet loss has happened.
Solution Approach 2:
The system dynamically changes the MBR parameter based on the actual codec bitrate requirements. Instead of using a fixed preconfigured MBR, the system adjusts the MBR parameter to match the actual transmission needs of the codec, thereby maintaining network resource optimization while preventing muting and communication quality deterioration.
3Manufacturing precision
If codec bitrate changes require reconfiguration of the MBR at the packet gateway, then bitrate compliance is maintained, but system complexity and processing overhead increase
Solution Approach 1:
The system implements self-service by automatically determining and adjusting the MBR based on the codec's inherent bitrate requirements. The packet gateway or relevant network element automatically identifies the codec type and applies the appropriate MBR without requiring manual intervention or complex reconfiguration processes, thereby maintaining bitrate compliance while reducing system complexity.
Solution Approach 2:
The patent replaces complex mechanical reconfiguration processes with automated parameter-based adjustment. Instead of requiring complex signaling and manual reconfiguration when codec bitrate changes, the system uses automated detection and parameter modification to adjust the MBR, significantly simplifying the process while maintaining bitrate compliance.
4Device complexity
If a fixed preconfigured MBR is used for all Internet telecommunications, then network management is simplified, but adaptability to different codec modes and communication types is reduced
Solution Approach 1:
The patent applies local quality by customizing the MBR configuration for each specific communication session based on the codec type and transmission requirements. Instead of using a uniform fixed MBR for all communications, the system adjusts the MBR locally for each session to match the specific needs of the codec and communication type, thereby maintaining simplicity while improving adaptability.
Solution Approach 2:
The system transitions from a static fixed MBR to a dynamic adaptive MBR that automatically adjusts based on the actual communication requirements. This dynamic approach allows the network to maintain simple management while achieving high adaptability to different codec modes and communication types through automated parameter adjustment.

AI summary
A method for dynamically adapting a maximum bitrate (MBR) configuration of an IP Multimedia Subsystem (IMS)/Rich Communication Services (RCS) application, includes receiving a signal from a client server for an IMS/RCS application, establishing a bearer channel for an Internet multimedia communication, the channel having an initial preconfigured MBR, determining a codec used to transmit the communication, determining the bitrate used by a codec, and modifying the MBR of the channel based on the bitrate of the codec.
