Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of additional services such as computing and data processing in mobile networks reduces the flexibility and scalability of the control plane, making it difficult to manage and maintain new services effectively.
Innovation Solution
A communication method and apparatus that allows terminal devices to request specific services from the core network by identifying a destination address and establishing a user plane connection, separate from the control plane, thereby improving scalability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If management functions of additional services (computing, data processing, perception) are added to the SMF network element on the control plane, then the mobile network can provide these additional services, but the flexibility and scalability of the control plane are reduced
Solution Approach 1:
The patent segments the network architecture by separating service management functions from the control plane. Independent service management network elements are introduced to handle computing, data processing, and perception services, while the control plane (SMF) retains only core session management functions. This segmentation resolves the contradiction by enabling service integration without increasing control plane complexity.
Solution Approach 2:
The patent introduces independent service management network elements as intermediaries between the terminal devices and the core network. These intermediary elements handle service-specific management tasks, allowing the SMF to remain focused on session management and avoiding the complexity increase that would result from consolidating all service management functions in the control plane.
2Productivity
If the SMF network element is reconfigured to manage both computing entities and UPF network elements, then computing resource scheduling flexibility is improved, but terminal device selection of specific SMF elements becomes more difficult and control plane flexibility is reduced
Solution Approach 1:
The patent segments the management responsibilities by separating service-specific management (handled by independent service management network elements) from session management (handled by SMF). This allows terminal devices to access services through service management elements without needing to select specific SMF elements, resolving the contradiction between scheduling efficiency and ease of operation.
Solution Approach 2:
The patent enables service management network elements to autonomously handle service-specific management tasks including resource allocation and scheduling. This self-service capability allows computing resources to be scheduled efficiently without requiring terminal devices to interact with or select specific SMF elements, thereby maintaining ease of operation while improving productivity.
3Adaptability or versatility
If more independent services are deployed on the user plane with management functions added to SMF, then service functionality is improved, but scalability for new service addition and maintenance becomes difficult
Solution Approach 1:
The patent segments service deployment by introducing independent service management network elements for each service type (computing, data processing, perception). This segmentation enables services to be deployed and maintained independently without affecting the core SMF, thereby improving scalability while maintaining enhanced service functionality.
Solution Approach 2:
The patent creates a universal service management architecture where independent service management network elements can handle multiple service types. Each service management element is designed to be multi-functional, capable of managing computing, data processing, and perception services, which improves scalability by allowing new services to be added through standardized interfaces without complex reconfiguration of the core network.
Data Source
AI summary
A communication method and a related apparatus. A terminal obtains first service information, where the first service information includes an identifier of a first service. The terminal sends a first service request to a core network element based on the first service information. The terminal sends data of the first service based on a destination address of the first service.
