Performance Data Streaming Service for 5G Network Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of modern radio access networks, particularly with the advent of 5G and Next Generation (NG) systems, necessitates flexible performance management solutions due to increased device diversity and data bandwidth demands, where traditional network devices often struggle to adapt to varying conditions without proprietary modifications, leading to a need for advanced data analytics and virtualization techniques.
Innovation Solution
The implementation of a Performance Data Streaming Service (PDSS) that enables authorized consumers to create, manage, and stream performance data from Network Functions (NFs), allowing for real-time monitoring and optimization of network performance across various radio access technologies, including 3GPP LTE, LTE-Advanced, and 5G networks, through standardized interfaces and service-based architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional network devices are used with proprietary physical implementations, then device functionality is maintained, but flexibility and adaptability to new network conditions deteriorate
Solution Approach 1:
The patent creates virtual copies of network functions (VNFs) that run on general-purpose computing systems. Instead of modifying physical devices, virtual instances are deployed that can be rapidly instantiated, configured, and migrated, providing flexibility without adding physical complexity to the underlying infrastructure.
Solution Approach 2:
The patent implements a universal virtualization platform where a single physical infrastructure can host multiple network functions through VNFs. This multi-functional approach allows the same hardware to adapt to different network conditions and requirements by deploying appropriate virtual network functions, eliminating the need for proprietary physical implementations for each function.
2Adaptability or versatility
If Network Function Virtualization is implemented to provide flexibility, then adaptability to network conditions improves, but system complexity increases
Solution Approach 1:
The patent introduces a network function virtualization layer as an intermediary between the physical infrastructure and network services. This virtualization layer manages the complexity by abstracting resource allocation, lifecycle management, and service deployment, allowing the physical system to remain simple while providing high adaptability through software-based network functions.
3Loss of time
If performance data streaming service is implemented for real-time monitoring, then network optimization response time improves, but data processing requirements increase
Solution Approach 1:
The patent extracts and streams only the critical performance data metrics needed for real-time optimization, rather than processing all generated data. The performance data streaming service selectively extracts key performance indicators from the virtualized network functions and delivers them in real-time, reducing the data processing burden while maintaining fast response capability for network optimization.

AI summary
Systems and methods of modifying stream information in an established streaming connection between a performance data streaming service (PDSS) producer and a PDSS consumer are described. The PDSS producer sends a request to get stream information, add a stream to the streaming connection, updated a stream to the streaming connection, or delete a stream from the streaming connection due to a reason such as addition or removal of measurement jobs, the measurement types to be reported by the stream being changed, or the measurement job being stopped. The PDSS consumer receives the request, takes the desired action, and provides a response to indicate whether the desired functionality has been carried out, identifying the streams affected.
