Solution Overview
Problem
Existing communication networks face challenges in efficiently managing and optimizing the interaction between wireless devices and core networks, particularly in handling multiple technologies and releases, which can lead to inefficiencies and compatibility issues.
Innovation Solution
The implementation of a service-based architecture within the core network, utilizing network functions that offer services to each other and other elements of the communication network via interfaces, allowing for dynamic discovery and interaction, and the use of a unified data management system to manage user and control plane functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service-based architecture is implemented in the core network, then flexibility and efficiency of communication networks are enhanced, but device complexity increases
Solution Approach 1:
The core network is segmented into independent service-based functional units (AMF, SMF, UPF, etc.) that can be deployed, managed, and scaled separately. Each network function operates as an independent component with well-defined interfaces, allowing the system to achieve flexibility through modular architecture while managing complexity through clear separation of concerns.
Solution Approach 2:
The service-based architecture implements universal interface standards (service-based interfaces) that allow different network functions to interact through common protocols and mechanisms. This multi-functionality enables the same architectural framework to support multiple technologies and releases simultaneously, enhancing adaptability without proportionally increasing complexity.
2Adaptability or versatility
If multiple technologies and releases are supported simultaneously, then adaptability improves, but compatibility issues and management complexity increase
Solution Approach 1:
The architecture uses configurable parameters and versioning mechanisms within service-based interfaces to support multiple technologies and releases. Network functions can be configured with different parameter sets to accommodate various technology versions, allowing the system to adapt to multiple standards while maintaining compatibility through controlled parameter management rather than hard-coded dependencies.
3Productivity
If dynamic discovery and interaction between network functions are enabled, then efficiency is improved, but system complexity increases
Solution Approach 1:
Network functions implement self-service capabilities through automated discovery mechanisms and self-configuration protocols. Each function can autonomously discover available services, establish connections, and configure interactions without manual intervention, improving operational efficiency while managing complexity through automation rather than centralized control.
Data Source
AI summary
A wireless device receives, from a session management function (SMF), a message for a protocol data unit (PDU) session establishment, wherein the message comprises a configuration information for determining one or more packets that are of a plurality of packets of a data unit (DU), and the configuration information indicates one or more protocols used for determining the plurality of packets. The wireless device determines, based on the configuration information, that a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU, and a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU.
