Network Management System for Wireless Service Level Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple networks of different service levels, such as a factory, it is challenging to manage and maintain the coexistence of packets with varying service levels, especially when transitioning from wired to wireless networks, leading to difficulties in satisfying the specific requirements of each network.
Innovation Solution
A network management system is implemented that integrates the management of communication systems, logically dividing them into partitions based on service levels, using information setting units to manage EPC, MBH, and LAN systems, ensuring packets are routed through specific logical partitions corresponding to their service levels, thereby avoiding the coexistence of packets with different service levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple networks with different service levels are flattened into a single wireless network, then network flexibility and ease of deployment are improved, but the ability to satisfy specific service level requirements for each network type deteriorates
Solution Approach 1:
The patent segments the flat wireless network into multiple virtual networks (VNets) based on service levels. Each VNet is assigned a specific service level (e.g., 5G-LTE, 5G-Advanced, 6G), allowing packets to be routed through appropriate virtual networks to satisfy their specific service level requirements while maintaining the underlying flat wireless infrastructure.
Solution Approach 2:
The patent introduces a service level gateway as an intermediary component that sits between the flat wireless network and the core network. This gateway performs service level determination, packet classification, and routing decisions, acting as a mediator that ensures packets are directed through the correct virtual network path to maintain service level integrity.
2Ease of operation
If wired networks are replaced with wireless networks, then ease of reconfiguration for high-mix low-volume production is improved, but the ability to maintain distinct service levels for different network types deteriorates
Solution Approach 1:
The patent applies segmentation by creating virtual network segments within the wireless infrastructure. Each service level (5G-LTE, 5G-Advanced, 6G) is represented as a distinct virtual network with its own routing policies and quality of service parameters, allowing wireless networks to maintain service level distinctions comparable to wired networks while preserving reconfiguration flexibility.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting network parameters such as bandwidth allocation, latency thresholds, and priority levels based on the service level of incoming packets. The service level gateway modifies packet handling parameters according to the determined service level, enabling the wireless network to adapt its behavior to match the requirements of different service levels.
3Productivity
If packets from different service levels are allowed to coexist in the same network, then network resource utilization is improved, but the precision of service level management deteriorates
Solution Approach 1:
The patent segments the network into multiple virtual networks, each dedicated to a specific service level. This segmentation allows packets from different service levels to coexist in the physical wireless infrastructure while being logically separated into different virtual networks, thereby maintaining both high resource utilization and precise service level management.
Solution Approach 2:
The service level gateway implements feedback mechanisms by continuously monitoring packet characteristics, network conditions, and service level requirements. Based on this feedback, the gateway dynamically adjusts routing decisions and resource allocation to ensure that service level management precision is maintained even as resource utilization is optimized.

AI summary
Constructed is a network management system which manages, in an integrated manner, a first communication system, a second communication system and a third communication system passed through by packets that are sent and received via wireless communication between a first device and a second device. The network management system performs information setting to these communication systems for dividing a communication system group, which includes these communication systems, into a plurality of logical partitions each corresponding to a plurality of different service levels based on the management information of each of these communication systems. A logical partition corresponding to a service level with regard to each of the plurality of different service levels is a partition passed through by packets that are sent and received via wireless communication between the first device and the second device belonging to that service level.
