Multi-RAT Carrier Switching for Throughput Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-carrier aggregation scenarios within wireless communication networks, ensuring the continuity of data transmission throughput during node switching between different Radio Access Technologies (RATs) is challenging, as existing methods fail to maintain seamless connectivity when switching between multiple RAT carriers.
Innovation Solution
A method and device for multi-carrier switching that involves receiving information about a secondary link by a target RAN node, establishing a connection with the corresponding RAN node, and determining an anchor point for carrier data division/aggregation control to ensure continuous data transmission across RATs, utilizing modules for message reception, connection establishment, and determining target RAN nodes for seamless data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single RAT link switching scheme is used for multi-carrier aggregation, then the switching process is simple, but the continuity of data transmission throughput cannot be ensured
Solution Approach 1:
The patent segments the multi-RAT carrier aggregation switching process into distinct phases: identifying a target RAN node for the first link, receiving second link information from the source node, establishing connections with the target node for both first and second links, and coordinating switching timing. This segmentation allows complex multi-RAT switching to be managed through structured, manageable steps that ensure data transmission continuity while maintaining reasonable implementation complexity.
2Productivity
If multi-RAT carrier aggregation is implemented to improve peak rate, then user throughput increases, but the complexity of node switching and connection management increases
Solution Approach 1:
The patent applies preliminary action by having the target RAN node receive and process the second link information before the actual switching occurs. The source RAN node prepares the target node in advance by providing necessary connection parameters, allowing the target node to be ready for immediate data transmission upon switching. This preliminary preparation reduces the complexity of real-time switching operations while maintaining high user peak rates through efficient multi-RAT carrier aggregation.

AI summary
A method for switching of multi-carrier and device are provided. The method comprises: receiving a message sent from a source RAN node corresponding to a first link and comprising information of a second link; according to the information of the second link, establishing a connection between a target RAN node corresponding to the first link and an RAN node corresponding to the second link, so as to perform data transmission. The first link is a link in a first Radio Access Technology (RAT) network, and the second link is a link in a second RAT network. Embodiments of the present invention can ensure the continuity of the throughput of data transmission during switching under aggregation of multiple RAT carriers.
