Relay Node Connection Management via Capability Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connection management in communication networks does not adequately consider the status and control information from relay connections, leading to non-optimal resource allocation and management, especially in scenarios involving mobile relays connected via air-interface.
Innovation Solution
Identifying intermediary nodes through capability information messages allows for setting connection parameters based on their specific capabilities, enabling dynamic adjustment of resources and improving connection management between relays and the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relays are introduced into RAN to enable indirect device connections, then connectivity coverage and device access are improved, but connection management complexity increases due to lack of relay-specific status and control information processing
Solution Approach 1:
The system performs preliminary identification of relay nodes by examining capability information messages before establishing connections. This advance classification allows the network to prepare appropriate connection management parameters and resource allocation strategies in advance, avoiding the complexity of handling relay-specific requirements during real-time connection management operations.
2Productivity
If relay nodes share connection resources among multiple devices, then resource utilization efficiency improves, but connection management precision deteriorates due to lack of relay-specific status information
Solution Approach 1:
The system implements feedback mechanisms where relay nodes provide status information about their connections and resource usage to the network. This feedback loop enables the network to accurately monitor relay performance, adjust resource allocation dynamically, and maintain precise connection management while sharing resources among multiple devices through the relay.
3Adaptability or versatility
If multi-RAT relays are deployed to provide diverse connectivity options, then service versatility improves, but network traffic load increases due to additional connection requirements
Solution Approach 1:
The system preliminarily identifies relay nodes capable of supporting multiple RATs by examining their capability information messages. This advance classification allows the network to pre-configure appropriate connection parameters and select optimal serving RATs, thereby managing multi-RAT relay traffic loads more effectively while maintaining service versatility.

AI summary
Providing connections to terminals in an access node of a first network. A message is received in the access node from a terminal, the message including capability information of the terminal. The terminal is identified in the access node on the basis of the received capability information as an intermediary node capable of relaying traffic between the first network and a second network. Parameters for a connection between the access node and the terminal are determined in the access node on the basis of the identification of the terminal as intermediary node and used in establishing the connection between the access node and the terminal.
