Relay Node Radio Bearer Configuration in Multi-Hop Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not specify how to configure a radio bearer for data transmission between a relay node and a node other than the anchor/donor node in multi-hop network architectures, leading to inefficiencies in data aggregation and dis-aggregation across relay nodes.
Innovation Solution
A method and apparatus for configuring a relay node that involves transmitting and receiving messages carrying information on radio bearers between nodes, allowing for the determination and configuration of radio bearers for user access, tunnel establishment, and QoS management across multiple relay nodes, enabling efficient data transmission and aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multi-hop network architecture is deployed to extend network coverage, then network coverage is improved, but data transmission efficiency between relay nodes deteriorates due to lack of radio bearer configuration specifications
Solution Approach 1:
The patent segments the data transmission path into multiple hops with intermediate relay nodes, each configured with specific radio bearers. The first node transmits configuration information to the second node (relay node), which then establishes dedicated radio bearers for data aggregation and dis-aggregation between hops, enabling efficient multi-hop data transmission while extending network coverage.
2Productivity
If relay nodes are introduced for data aggregation, then network capacity is improved, but configuration complexity deteriorates due to unspecified radio bearer setup procedures
Solution Approach 1:
The patent applies preliminary action by having the first node transmit configuration information about radio bearers to the second node before data transmission begins. This pre-configuration establishes the necessary radio bearers and transmission parameters in advance, simplifying the overall configuration process while enabling relay nodes to efficiently aggregate and forward data.
3Adaptability or versatility
If control signaling is transmitted via user plane messages, then signaling flexibility is improved, but control plane overhead increases
Solution Approach 1:
The patent uses an intermediary approach by establishing a dedicated control plane interface between the first node and the second node. Control signaling is transmitted through this dedicated control plane message mechanism rather than through user plane messages, separating control functions from data transmission. This reduces control plane overhead while maintaining flexibility in radio bearer configuration and data transmission management.
