Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies fail to consider the multiple capabilities supported by network elements during discovery, leading to inefficiencies such as increased signaling overheads and complexity due to separate discovery processes for individual capabilities.
Innovation Solution
A method for selecting target core network elements based on multiple expected capabilities, using a first core network element to determine discovery priorities and reduce the number of interactions by identifying network elements that support the required capabilities, thereby optimizing the discovery process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate discovery processes are used for individual capabilities, then each capability can be discovered independently, but signaling overheads and system complexity increase
Solution Approach 1:
The patent combines multiple capability discovery processes into a single unified discovery process. The network element discovery request can carry multiple expected capability types simultaneously, and the network element management function returns a set of candidate network elements that can satisfy multiple capability requirements at once, thereby reducing the number of separate discovery interactions and lowering system complexity
2Reliability
If separate discovery processes are used for individual capabilities, then each capability can be discovered independently, but signaling overheads increase
Solution Approach 1:
Multiple capability discovery requests are merged into a single signaling interaction. The discovery request message can include multiple expected capability types, and the response message provides a unified set of candidate network elements, significantly reducing the quantity of signaling messages exchanged compared to separate discovery processes for each capability
3Adaptability or versatility
If network elements support multiple capabilities, then service functionality is enhanced, but the discovery process becomes more complex
Solution Approach 1:
The patent implements a universal discovery mechanism that handles network elements with multiple capabilities through a single standardized process. The network element management function maintains capability information for network elements and can query candidates based on multiple expected capabilities simultaneously, allowing the system to leverage multi-functional network elements without increasing discovery process complexity
Solution Approach 2:
The discovery process merges multiple capability queries into a single operation, where the network element management function processes multiple expected capability types together and returns a unified candidate set, simplifying the discovery process even when network elements support multiple capabilities
