Terminal Capability Signaling for Data Unit Set Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in handling data unit sets due to the lack of support for data unit set handling capabilities in terminal devices, leading to ineffective data transmission and user experience issues.
Innovation Solution
Terminal devices and network devices are equipped with processors and memories to facilitate the exchange of data unit set handling capabilities, allowing network devices to perform data unit set handling only for devices that support this capability, ensuring optimal data transmission and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the core-network device sends data unit set handling parameters to the access-network device, then unified handling of multiple data packets is enabled, but the access-network device cannot effectively process data from terminal devices that do not support data unit set handling
Solution Approach 1:
The patent implements dynamic capability indication where terminal devices dynamically indicate their data unit set handling capability to the access-network device. The access-network device then dynamically adjusts its processing mode based on the terminal's capability indication, switching between data unit set handling and conventional data packet handling as needed.
Solution Approach 2:
The patent applies local quality by enabling data unit set handling only for specific terminal devices that support this capability, while maintaining conventional handling for devices that do not support it. The access-network device selectively applies different processing methods to different data streams based on individual terminal capabilities.
2Adaptability or versatility
If data unit set handling is implemented for all terminal devices, then unified processing of data packets is achieved, but terminal devices without support cannot be properly served
Solution Approach 1:
The patent implements a feedback mechanism where terminal devices send capability indication information to the access-network device. This feedback allows the network device to determine whether to apply data unit set handling or conventional handling, ensuring that service reliability is maintained for legacy devices while enabling advanced handling for capable devices.
Solution Approach 2:
The patent segments terminal devices into two groups: those that support data unit set handling and those that do not. The access-network device applies different processing methods to each segment based on their capability, ensuring that unified processing is applied only where appropriate while maintaining compatibility with legacy devices.
3Productivity
If the access-network device applies data unit set handling parameters to all data, then processing efficiency is improved, but devices without capability support experience transmission failures
Solution Approach 1:
The patent applies preliminary action by having terminal devices indicate their capability status before actual data transmission begins. The access-network device receives and stores this capability information in advance, allowing it to prepare the appropriate processing method before data arrives, thus preventing transmission errors while maintaining efficiency.
Solution Approach 2:
The patent changes the processing parameters dynamically based on terminal capability. When a terminal indicates support for data unit set handling, the access-network device switches to using data unit set handling parameters; otherwise, it uses conventional data packet parameters. This parameter adaptation prevents transmission errors for incompatible devices.
