Migration Manager for Base Station Application Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication base stations face inefficient hardware utilization and service disruptions due to varying workloads and maintenance needs, which can lead to suboptimal resource management and power consumption.
Innovation Solution
A migration manager component is introduced to transfer applications between computing devices, allowing for workload distribution and maintenance without disrupting terminal device connections by initializing a second application to manage communication connections, duplicating the state of the first application, and synchronizing timers to ensure continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If applications are transferred between computing devices to balance workload, then hardware utilization efficiency improves, but service continuity may be disrupted
Solution Approach 1:
A second application instance is initialized on the target computing device before the first application is stopped. The state of the first application is duplicated to the second application in advance, ensuring that when the transfer occurs, the second application is already prepared to take over immediately, thus maintaining service continuity while enabling workload balancing.
2Reliability
If hardware maintenance is performed on computing devices, then system reliability improves, but communication service may be interrupted
Solution Approach 1:
Before maintenance is performed on a computing device, the application managing communication connections is transferred to another computing device. The state is duplicated in advance, and the second application is initialized beforehand, ensuring that when the first device undergoes maintenance, the communication service continues uninterrupted through the second device.
3Reliability
If application state is duplicated during transfer, then service continuity is maintained, but data transmission time increases
Solution Approach 1:
The state of the first application is duplicated to create the second application instance. This copying process enables the second application to take over immediately when the transfer occurs, maintaining service continuity. The state duplication includes all necessary data and configuration information, ensuring seamless transition.
