Communication Device Multi-Model Requests Through Unified NWDAF Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication networks, a model receive end can only request one model from a model transmit end at a time, leading to increased network load and signaling consumption when multiple models are needed simultaneously.
Innovation Solution
A method and apparatus that allow a communication device to request and receive multiple models simultaneously by using a Network Data Analytics Function (NWDAF) split into an MTLF and AnLF, enabling simultaneous subscription and notification of trained ML models, and providing a mechanism for requesting and obtaining multiple models through a unified interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a model receive end requests models one by one from a model transmit end, then the request processing is simple, but the network load and signaling consumption increase when multiple models are needed simultaneously
Solution Approach 1:
The patent combines multiple model requests into a single request message. The model receive end can request multiple models simultaneously through one unified request interface, and the model transmit end returns multiple models in one response message. This merging approach reduces the number of signaling exchanges and network load while maintaining simple request processing logic on both ends.
2Productivity
If a model receive end requests multiple models simultaneously, then the network efficiency improves, but the request and response message structures become more complex
Solution Approach 1:
The patent designs a universal request interface that can handle both single model requests and multiple model requests through the same message structure. The request message includes a field to indicate the number of models requested, and the response message can return one or multiple models based on this indication. This multi-functional design allows the system to maintain simple message structures while achieving high network efficiency through simultaneous multiple model requests.
