Remote UE Relay Selection via Access Control Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network congestion situations, remote UEs face challenges in accessing the network efficiently due to unclear access control mechanisms, leading to resource wastage, battery consumption, and service connectivity delays, especially when proximity communication services are required.
Innovation Solution
A method for a remote UE to select an appropriate relay UE by comparing received access control information with its own information, prioritizing matching access class, configuration, and access control mechanism details, and attempting a connection with the most suitable relay UE to optimize network access during congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote UE attempts network access during congestion without clear access control mechanisms, then network connectivity may be achieved, but resource waste and battery consumption increase
Solution Approach 1:
The remote UE performs preliminary actions by receiving and storing access control information from relay UEs before attempting network access. This allows the UE to evaluate multiple relay options in advance, compare their access control parameters, and select the most suitable relay without repeated failed access attempts, thereby reducing unnecessary battery consumption while maintaining connectivity reliability
Solution Approach 2:
The system implements feedback mechanisms where relay UEs transmit access control information (such as access class, configuration parameters, and access control mechanism details) back to remote UEs. This feedback enables remote UEs to make informed decisions about which relay to connect to, avoiding wasted energy on unsuitable relays while ensuring successful network access
2Reliability
If remote UE attempts network access during congestion without clear access control mechanisms, then network connectivity may be achieved, but service connectivity delay increases
Solution Approach 1:
The remote UE receives and evaluates access control information from multiple relay UEs in advance, performing preliminary comparisons of access classes, configuration parameters, and access control mechanisms. This preliminary evaluation enables the UE to immediately connect to the most suitable relay when access is needed, eliminating delays that would result from trial-and-error access attempts
Solution Approach 2:
Relay UEs provide feedback information including access control parameters and mechanism details that enable remote UEs to quickly assess relay suitability. This feedback mechanism reduces service connectivity delay by allowing remote UEs to make rapid, informed decisions about which relay to connect to during congested network conditions
3Ease of operation
If remote UE selects relay UE without comparing access control information, then connection establishment is simpler, but resource waste increases
Solution Approach 1:
The remote UE autonomously performs self-service by receiving access control information from multiple relay UEs, comparing the information against its own requirements, and independently selecting the most suitable relay. This self-service mechanism balances operational simplicity with resource efficiency, as the UE handles the comparison process automatically without requiring complex external coordination, thereby reducing network resource waste while maintaining ease of operation

AI summary
One disclosure of the present specification provides a method by which a remote terminal selects any one from among relay terminals in a situation in which access control is applied because of network congestion. The method can comprise the steps of: receiving first information related to the access control from at least one of the relay terminals; comparing the first information with second information which is possessed by the remote terminal; selecting, from among the relay terminals, the relay terminal having transmitted the first information, when the first information completely coincides with the second information; and attempting a connection with the selected relay terminal.
