IMS Data Channel Establishment via Capability and Subscription Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of clear regulations and mechanisms for establishing a data channel (DC) interface in the next-generation Internet Protocol (IP) Multimedia Subsystem (IMS) network, hindering effective interaction and channel establishment processes.
Innovation Solution
A method and apparatus for information processing that involves a first network device receiving a message with DC information and determining whether to send a second message to a network function based on subscription, user contract, configuration, or terminal/network capability information, and the network function performing actions related to channel establishment, processing, or policy determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a data channel establishment mechanism is introduced to enhance communication functionality, then the versatility and capability of the IMS network are improved, but the device complexity and regulatory requirements increase due to the lack of clear interface regulations and establishment mechanisms
Solution Approach 1:
The patent segments the data channel establishment process into distinct phases: capability indication in initial messages, subscription information exchange, and conditional establishment based on user contract information. This segmentation transforms a complex monolithic process into manageable discrete steps, reducing overall system complexity while maintaining versatility
Solution Approach 2:
The patent implements preliminary capability indication mechanisms where network devices declare their data channel support capabilities in advance during initial communication setup. This preliminary action allows subsequent stages to proceed efficiently without re-negotiating fundamental capabilities, reducing complexity in the establishment phase while preserving adaptability
2Reliability
If multiple information types (subscription information, user contract information, configuration information) are used to determine channel establishment, then the reliability and appropriateness of channel establishment decisions are improved, but the loss of information and processing overhead increase
Solution Approach 1:
The patent applies local quality by treating different information types (subscription information, user contract information, configuration information) as having different weights and applicability in different contexts. Each information type is processed and evaluated according to its specific relevance to the current establishment scenario, optimizing the balance between decision reliability and processing efficiency by not uniformly processing all information types in all situations
3Productivity
If a comprehensive framework for data channel establishment is implemented, then the productivity and efficiency of communication systems are improved, but the device complexity increases due to the need to manage multiple information types and decision criteria
Solution Approach 1:
The patent introduces an intermediary decision-making framework that mediates between multiple information sources (subscription information, user contract information, configuration information) and the final channel establishment decision. This intermediary layer standardizes the processing of diverse inputs through a unified evaluation mechanism, improving productivity by streamlining the decision process while managing complexity through modular architecture
