OAM System Configures Donor Base Station for Mobile Relay Node
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to configure a new Donor base station or cell for mobile relay nodes when they are moving, as they assume a fixed RN and do not account for frequent handovers of DeNB/Donor Cell.
Innovation Solution
An Operation and Maintenance (OAM) system selects and configures a suitable DeNB/Donor Cell based on the mobile RN's position information or moving path, allowing seamless handover and continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the OAM system configures DeNB/Donor Cell for a mobile RN based on position information or moving path, then the mobile RN can maintain continuous connectivity during motion, but the system complexity and configuration difficulty increase compared to fixed RN scenarios
Solution Approach 1:
The OAM system pre-configures a list of candidate DeNBs/Donor Cells for the mobile RN based on its moving path or position information before handover is needed. This preliminary configuration enables the mobile RN to quickly switch to a pre-identified target DeNB/Donor Cell, maintaining connectivity continuity while reducing the complexity of real-time decision-making during motion.
2Reliability
If the mobile RN frequently hands over between different DeNB/Donor Cells during motion, then the RN can maintain optimal signal quality, but the handover frequency and service interruption risk increase
Solution Approach 1:
The OAM system pre-identifies and configures a list of candidate target DeNBs/Donor Cells along the mobile RN's moving path or based on position information. When handover is needed, the mobile RN can immediately switch to a pre-configured target, reducing handover time and minimizing service interruption while maintaining optimal signal quality.
3Adaptability or versatility
If the system uses position information or moving path for DeNB/Donor Cell selection, then the adaptability to mobile RN scenarios is improved, but the measurement and detection difficulty increases
Solution Approach 1:
The OAM system acts as an intermediary that acquires position information or moving path of the mobile RN from external sources (such as GPS or network positioning systems) and uses this information to pre-configure appropriate DeNBs/Donor Cells. This intermediary approach enables the system to adapt to mobile RN scenarios without requiring the mobile RN itself to perform complex position measurement and detection.

AI summary
Disclosed are a method and device for configuring a Donor base station or a Donor cell for a mobile relay node. The method includes: an operation administration and maintenance (OAM) system obtains position information about a mobile relay node (RN) and determines a standby Donor base station or a standby Donor cell which can be accessed by the mobile RN according to the position information thereof; and the OAM system indicates the standby Donor base station or the standby Donor cell to a serving Donor base station of the mobile RN or indicates the standby Donor base station or the standby Donor cell to the serving Donor base station of the mobile RN through the mobile RN, so that the serving Donor base station of the mobile RN selects a target Donor base station or a target Donor cell for the mobile RN. By way of the present invention, the DeNB or the Donor Cell can be configured for the mobile RN when the mobile RN is moving.
