Network Device DC Negotiation Handling Non-DC Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DC negotiation mechanisms in 3GPP networks fail to handle scenarios where a second terminal or network does not support data channel capabilities, leading to unclear communication and potential failures in DC setup.
Innovation Solution
A communication method and apparatus that determine DC negotiation results and indication information for both first and second devices, enabling proper handling of DC capability support or lack thereof, and facilitating the exchange of application information and DC setup requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing DC negotiation mechanism carries DC capability tags in initial INVITE requests or SIP response messages, then DC setup can be initiated between terminals, but the mechanism fails when one terminal or network does not support DC capabilities, leading to unclear communication and potential negotiation failures
Solution Approach 1:
The patent introduces a network device as an intermediary that receives DC negotiation results from both the first and second devices, processes this information, and determines comprehensive DC indication information. This mediator resolves the contradiction by centralizing the negotiation logic and providing a unified decision point that can handle cases where either device lacks DC support, thereby improving reliability while maintaining adaptability through centralized intelligence.
2Reliability
If the DC negotiation mechanism requires both terminals to support DC capabilities, then DC functionality can be established, but the system lacks adaptability when one terminal or network does not support DC
Solution Approach 1:
The patent implements a feedback mechanism where the network device receives DC negotiation results from both devices, processes this feedback information, and determines appropriate DC indication information. This feedback loop enables the system to adapt to various scenarios including when one device does not support DC, allowing the network to make informed decisions about DC setup while maintaining high reliability and broad adaptability.
