Network Element User Service Node Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, managing network resources effectively after fine-grained division of network element functions to meet user-centric requirements is a challenge, as existing methods lack flexibility and adaptability in allocating and updating user service nodes based on terminal device needs.
Innovation Solution
A network resource management method where a first network element receives messages to create or update user service nodes based on terminal device identifiers, subscription information, and policy information, allowing for flexible creation, selection, and dynamic adjustment of user service nodes to match terminal device requirements, including updating resources and network capabilities as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fine-grained function division is performed on network element functions to meet user-centric requirements, then adaptability to user needs is improved, but device complexity increases
Solution Approach 1:
The network element functions are divided into fine-grained functional units, with each network element responsible for specific user service nodes. This segmentation allows the system to adapt to different user needs by activating specific functional units while keeping the overall system manageable through clear functional boundaries.
Solution Approach 2:
The network element can dynamically create, select, update, and release user service nodes based on terminal device requirements and subscription information. This dynamic capability enables the system to adapt to changing user needs without requiring complete reconfiguration of the network architecture.
2Adaptability or versatility
If user service nodes are dynamically created and updated based on terminal device needs, then resource allocation flexibility is improved, but management complexity increases
Solution Approach 1:
The network element receives feedback from terminal devices through service request messages containing device identifiers and capability information. Based on this feedback, the network element dynamically creates or selects appropriate user service nodes, ensuring resource allocation flexibility while maintaining manageable complexity through feedback-driven decision making.
Solution Approach 2:
The network element autonomously manages the lifecycle of user service nodes by automatically creating, selecting, updating, and releasing nodes based on received service requests and subscription information, without requiring manual intervention. This self-service capability reduces management complexity while maintaining high resource allocation flexibility.
3Productivity
If service request information is directly sent to user service nodes, then communication efficiency is improved, but network element coordination complexity increases
Solution Approach 1:
The network element acts as an intermediary between terminal devices and user service nodes. It receives service request messages from terminal devices, determines the appropriate user service node, and forwards requests accordingly. This intermediary role simplifies coordination by providing a centralized decision-making point while enabling direct communication between terminal devices and service nodes.

AI summary
This application provides a network resource management method and a communication apparatus. The network resource management method includes: A first network element receives a first message from a second network element. The first message carries an identifier of a first terminal device, and the first message is used to request to create or select a first user service node corresponding to the first terminal device. Further, the first network element creates or selects the first user service node based on the identifier of the first terminal device, where the first user service node is configured to provide a network service for the first terminal device.
