PDN Connection Configuration for User Plane Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face inefficiencies in data transfer due to the misuse of control plane data transfer for user plane only services, such as IMS and equipment management, which are not suitable for DoNAS, leading to suboptimal performance and service experience.
Innovation Solution
A mechanism is introduced to configure PDN connections with a user plane only indication, allowing terminal devices and MMEs to perform user plane setup effectively, ensuring data transfer efficiency by switching from control plane to user plane data transfer when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control plane data transfer (DoNAS) is used for user plane only services, then data transfer can be established, but data delivery efficiency deteriorates and service experience worsens
Solution Approach 1:
The system dynamically determines the data transfer path based on service type. The terminal device and network side interact through signaling to identify whether a service is control plane only or user plane only, and switch between DoNAS and user plane data transfer accordingly. This dynamic adaptation resolves the contradiction by ensuring optimal performance for each service type.
Solution Approach 2:
The invention changes the parameter of data transfer path selection based on service characteristics. By introducing service type identification and using it to select between different data transfer mechanisms (control plane vs user plane), the system optimizes both efficiency and service experience for different应用场景.
2Productivity
If user plane setup is performed for all PDN connections, then data transfer efficiency improves, but device complexity and signaling overhead increase
Solution Approach 1:
The system applies different data transfer mechanisms to different PDN connections based on their specific requirements. Instead of uniformly setting up user plane for all connections, the invention selectively configures user plane only for services that require it (like IMS and equipment management), while using DoNAS for control plane only services. This localized optimization reduces unnecessary signaling overhead while maintaining efficiency where needed.

AI summary
A method for communications is proposed. The method may comprise transmit a request for a packet data network connection of the terminal device to a network node. The method may further comprise receiving a response to the request from the network node. The response may indicate whether user plane setup is needed for data transfer on the packet data network connection.
