Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods result in terminal devices downloading data channel applications that are not supported by peer devices, leading to resource wastage and establishment failures due to mismatched DC capabilities between communication parties.
Innovation Solution
A core network device processes a data channel application list by obtaining and combining the capabilities of both terminal devices, generating a list that aligns with their actual support, thereby reducing the likelihood of unsupported application downloads and failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network delivers one application list including all APPs before the terminal device downloads an APP, then the terminal device can select from the APP list, but the terminal device may download a DC application that is not supported by the peer terminal device
Solution Approach 1:
The core network device performs preliminary action by obtaining and processing capability information from both terminal devices before generating the application list. This preliminary capability assessment ensures that only compatible applications are included in the delivered list, preventing terminal devices from downloading unsupported applications while maintaining selection flexibility.
Solution Approach 2:
The core network device acts as an intermediary between the terminal devices and the application list. It mediates the interaction by filtering and processing the application list based on the capability information obtained from both terminals, ensuring compatibility while preserving the user's selection freedom.
2Ease of manufacture
If the terminal device selects an APP from the APP list without capability verification, then the download process is simple, but resource waste and establishment failures occur due to mismatched DC capabilities
Solution Approach 1:
The core network device performs preliminary capability assessment and application list filtering before the terminal device initiates the download process. This preliminary action prevents resource waste by ensuring only compatible applications are made available for download, eliminating the need for complex capability verification during the download process itself.
3Reliability
If each APP establishes its own corresponding application DC to meet different QoS requirements, then service quality is improved, but the complexity of capability matching and application selection increases
Solution Approach 1:
The core network device serves as an intermediary that handles the complex capability matching and application list generation. It obtains capability information from both terminals, processes the matching logic, and delivers a pre-filtered application list to the terminal device, thereby simplifying the overall system complexity while maintaining QoS fulfillment through dedicated application DCs.
