Base Station Service Segmentation for Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, when an abnormality is detected, existing technologies may stop all services provided by a base station device, including mission-critical services (MCS) like traffic control and remote medicine, which can lead to service disruptions and accidents if the abnormality is not addressed promptly.
Innovation Solution
A communication system with a first server providing a first service and a second server providing a higher-priority service, where the base station device blocks communication with the first server upon detecting an abnormality in the first server, ensuring the higher-priority service continues uninterrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all services provided by a base station device are stopped when an abnormality is detected, then the communication system is protected from the abnormality, but the availability of mission-critical services deteriorates
Solution Approach 1:
The patent segments services into different priority levels (first priority and second priority). When an abnormality is detected, only services of the first priority level are stopped, while services of the second priority level (mission-critical services) continue to operate. This segmentation allows the system to protect itself from abnormalities while maintaining essential services.
Solution Approach 2:
The patent applies local quality by treating different services differently based on their priority levels. Instead of uniformly stopping all services, the system selectively stops only those services that are not mission-critical, while maintaining services that require high availability. This localized approach ensures system protection without compromising essential functionality.
2Productivity
If mission-critical services continue to operate when an abnormality is detected, then service availability is maintained, but the risk of system compromise increases
Solution Approach 1:
By segmenting services into priority levels, the patent enables mission-critical services to continue operating while non-critical services are isolated. This segmentation reduces the risk of system compromise by limiting the impact of abnormalities to only non-essential services.
Solution Approach 2:
The patent introduces a priority level classification as an intermediary mechanism that mediates between system protection and service continuity. This intermediary allows the system to make informed decisions about which services to maintain during abnormalities, balancing security and availability requirements.
3Productivity
If services are differentiated by priority levels, then selective service maintenance during abnormalities is enabled, but system complexity increases
Solution Approach 1:
The patent applies universality by using a standardized priority level classification system that can be applied across multiple services and base station devices. This universal approach simplifies the complexity by providing a consistent framework for service differentiation rather than requiring custom solutions for each service.

AI summary
In order to enable the protection of a system in which an abnormality is detected even while restricting the degradation of availability of a service provided by a base station device, a communication system in an exemplary embodiment has a first server which provides a first service, a second server which provides a second service, and a first base station device communicating with the first and second servers, wherein in the case where the second service has a higher priority than the first service, a communication path between the first base station device and the first server is cut off when an abnormality is detected from the first server.
