Base Station Management for Multi-Scheme Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when a base station fails, existing methods struggle to accommodate wireless terminals from the failed base station's coverage area in environments where multiple wireless schemes coexist, as neighboring base stations may not implement the same wireless scheme, leading to service disruptions.
Innovation Solution
A base station management method and apparatus that create a list of nearby base stations capable of covering the failed base station's area, selecting one that can implement the scheduled wireless scheme of the failed base station during its scheduled period, and setting it to provide that scheme to the affected area, even if it involves scheme multiplexing or idle resources.

Engineering Contradiction Analysis
1Reliability
If a neighboring base station expands its coverage area to accommodate terminals from a failed base station, then the coverage area is recovered, but the wireless terminals cannot be accommodated if the neighboring base station implements a different wireless scheme
Solution Approach 1:
The patent applies dynamics by enabling base stations to dynamically switch between multiple wireless schemes (e.g., LTE and 5G NR) based on real-time needs. When a base station fails, the system can dynamically select a neighboring base station that supports the required wireless scheme and activate it to provide service, rather than being constrained by static scheme assignments.
Solution Approach 2:
The patent utilizes parameter changes by allowing base stations to change their operational wireless scheme parameter according to service requirements. The system monitors which wireless schemes are available at neighboring base stations and selects appropriate ones to maintain service continuity, effectively changing the scheme parameter to match the failed base station's requirements.
2Device complexity
If base stations are assigned fixed wireless schemes, then system complexity is reduced, but the ability to accommodate terminals during base station failures in multi-scheme environments is limited
Solution Approach 1:
The patent applies universality by enabling base stations to support multiple wireless schemes (LTE and 5G NR) simultaneously or alternatively. This multi-functionality allows any base station to potentially serve terminals regardless of which scheme the failed base station used, increasing service recovery capability while maintaining manageable complexity through centralized coordination.
Solution Approach 2:
The system performs preliminary action by pre-configuring neighboring base stations with knowledge of multiple wireless schemes they can support. This advance preparation ensures that when a failure occurs, the system can immediately identify suitable replacement base stations without complex real-time negotiations, balancing preparedness with operational simplicity.

AI summary
A base station information DB (11) of a base station management apparatus (1) stores base station information that indicates wireless schemes that can be implemented by base stations (5), scheduled periods for implementation of the wireless schemes, and coverage areas of the base stations (5) in which wireless terminals can be accommodated. A use base station selection unit (14) creates a list of base stations (5) that can cover an entirety or part of a coverage area of a failed base station, which is a base station (5) that has failed, with reference to the base station information, selects a base station (5) that can implement an implementation-scheduled wireless scheme, which is a wireless scheme that is scheduled to be implemented by the failed base station, during a scheduled implementation period, which is the scheduled period for implementation of the implementation-scheduled wireless scheme of the failed base station, from among the base stations (5) included in the list, and sets the selected base station (5) so as to provide the implementation-scheduled wireless scheme to the coverage area of the failed base station during the scheduled implementation period.
