Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment and management of uplink classifiers and branching points in Next Generation wireless networks, such as 5G NR, are complex due to limited resources and varying application service requirements across different locales, necessitating dynamic management and selection of application service hosts based on factors like FQDN, device location, and resource utilization.
Innovation Solution
An uplink classifier and branching point service that dynamically selects application service hosts among available sites using fully qualified domain names, end device location, and performance metrics, managing insertion and deletion of uplink classifiers and branching points through serial, distributed, or hybrid architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink classifiers and branching points are deployed to bring application services closer to users, then service delivery optimization improves, but device complexity and management complexity increase
Solution Approach 1:
The patent introduces a Service Management Function (SMF) as an intermediary to manage uplink classifiers and branching points. The SMF receives service requirements from application functions, determines appropriate uplink classifiers/branching points based on device location and network conditions, and configures them accordingly. This intermediary approach simplifies the complexity by centralizing management decisions while enabling distributed service delivery optimization.
Solution Approach 2:
The patent implements dynamic selection and configuration of uplink classifiers and branching points based on real-time network conditions, device location, and service requirements. The system can dynamically insert, modify, or remove uplink classifiers in the data path as devices move or service demands change, allowing the network to adaptively optimize service delivery without manual reconfiguration.
2Productivity
If uplink classifiers are dynamically managed based on device location and network conditions, then service routing efficiency improves, but control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the SMF continuously monitors device location, network conditions, and service performance metrics. Based on this feedback, the SMF dynamically adjusts the configuration and placement of uplink classifiers to optimize routing efficiency. The system receives status information from the network and uses this feedback to make informed decisions about classifier insertion, modification, or removal.
Solution Approach 2:
The patent enables the system to automatically manage uplink classifiers without manual intervention. The SMF autonomously determines when and where to insert uplink classifiers based on service requirements and network conditions, configures them with appropriate rules, and manages their lifecycle. This self-service approach reduces control complexity by automating decision-making processes that would otherwise require manual network configuration.
3Adaptability or versatility
If multiple application service hosts are supported across different locales, then service versatility improves, but resource management complexity increases
Solution Approach 1:
The patent creates a universal management framework through the SMF that can handle multiple application services across different locales through a single unified interface. The SMF is designed to work with various types of application functions and service requirements, providing a multi-functional platform that manages uplink classifiers for diverse services (enhanced mobile broadband, ultra-reliable low-latency communications, massive machine type communications) without requiring separate management systems for each service type.
