Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanisms for providing services in 5G RAN, transport, and core network environments often fail to satisfy traffic characteristics and performance requirements, leading to poor user experiences due to resource consumption and inability to handle lost traffic effectively.
Innovation Solution
A Self-Organizing Network (SON) system that determines RAN, core, and transport network capabilities based on specific performance requirements, generating configuration settings to establish a network slice-based service area, thereby addressing each domain to improve user experience and conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current mechanisms are used to provide services in 5G RAN, transport, and core network environments, then service provision is possible, but traffic characteristics and performance requirements are not satisfied, leading to poor user experiences
Solution Approach 1:
The patent segments the network into three distinct self-organizing systems: RAN-SON for radio access network optimization, Core-SON for core network optimization, and Transport-SON for transport network optimization. Each SON independently optimizes its domain based on performance measurements, enabling targeted improvements for different traffic characteristics and service requirements without compromising overall user experience
Solution Approach 2:
The patent implements dynamic parameter adjustment by having each SON continuously measure performance metrics and modify configuration parameters accordingly. RAN-SON adjusts radio access parameters, Core-SON modifies core network settings, and Transport-SON tunes transport parameters to satisfy specific traffic characteristics and performance requirements, thereby improving both reliability and user experience
2Loss of energy
If services are provided without addressing each domain specifically, then resource consumption occurs, but the inability to handle lost traffic effectively worsens service quality
Solution Approach 1:
Each domain (RAN, core network, transport network) operates its own self-organizing system that autonomously monitors performance and adjusts parameters without external intervention. This self-service capability enables each domain to independently handle traffic losses and optimize resource allocation, improving traffic handling reliability while reducing overall resource consumption through localized optimization
Solution Approach 2:
The patent implements preliminary performance measurements and parameter adjustments by each SON before traffic loss occurs. By continuously monitoring performance metrics and proactively optimizing parameters, each domain prepares to handle potential traffic losses effectively, preventing service degradation before it impacts user experience

AI summary
A device may receive performance requirements for a service, and may receive RAN factors that influence a RAN, core factors that influence a core network, and transport factors that influence a transport network. The device may determine a RAN capability to satisfy the performance requirements, and may determine a core capability to satisfy the performance requirements. The device may determine a transport capability to satisfy the performance requirements, and may determine RAN configuration settings, core configuration settings, and transport configuration settings based on the RAN capability, the core capability, and the transport capability, respectively. The device may generate a RAN SON based on the RAN configuration settings, a core SON based on the core configuration settings, and a transport SON based on the transport configuration settings. The device may create a network slice based service area based on the RAN SON, the core SON, and the transport SON.
