Relay Device Handover Pre-Configuration for Train Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The relay technology in high-speed public transportation vehicles, such as trains, experiences prolonged handover delays and service interruptions due to the change of Donor E-UTRAN Node B, leading to poor service continuity and quality of service.
Innovation Solution
A handover processing method and system that involves sending auxiliary information to obtain pre-configured parameters before the source Donor E-UTRAN Node B makes a handover decision, allowing for pre-configuration of resources and reducing the need for real-time reconfiguration during the handover process, thereby shortening handover delays and ensuring service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If relay technology is used in high-speed public transportation vehicles, then network coverage and link capacity are improved, but handover delay and service interruption time are prolonged
Solution Approach 1:
The patent applies preliminary action by having the relay device obtain pre-configured parameters from the target Donor E-UTRAN Node B before the handover decision is made. This allows resource configuration to be prepared in advance, so that when handover occurs, the relay device can quickly switch to the target node using pre-configured resources, thereby reducing handover delay while maintaining extended network coverage
2Area of stationary object
If relay device traverses multiple cells, then wider network coverage is obtained, but service continuity deteriorates due to prolonged service interruption time
Solution Approach 1:
The patent resolves this contradiction by implementing preliminary configuration of handover parameters and resources before the relay device actually hands over between cells. The relay device obtains pre-configured parameters from the target Donor E-UTRAN Node B in advance, allowing seamless transition during cell traversal. This maintains service continuity while enabling the relay device to traverse multiple cells for wider coverage

AI summary
Embodiments of the present disclosure disclose a handover processing method. The method includes: before a source Donor E-UTRAN Node B (DeNB) makes a handover decision, sending auxiliary information for obtaining a pre-configured parameter; receiving the pre-configured parameter; and performing a handover from the source DeNB to a target DeNB according to the pre-configured parameter. The relay device includes: a first sending module, configured to send, before a source DeNB makes a handover decision, auxiliary information for obtaining the pre-configured parameter; a first receiving module, configured to receive the pre-configured parameter; and a handover module, configured to perform a handover from the source DeNB to a target DeNB according to the pre-configured parameter. According to the embodiments of the present disclosure, the technical problem that the service interruption of the UE controlled by the relay device is prolonged due to a long delay in the handover operation is solved.
