UE Resource Conflict Resolution for Multi-Network Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, user equipment (UE) may face capability conflicts when attempting to operate on multiple networks simultaneously, leading to conflicts between first and second radio resources, particularly in multiple universal subscriber identity module (MUSIM) operations, which can result in data transmission delays.
Innovation Solution
The UE autonomously identifies capability conflicts between first and second resources when connecting to multiple networks and proactively disables the first resource, transmitting disable information to the first network, thereby resolving the conflict before service initiation in the second network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE simultaneously operates on multiple networks (first network and second network), then the service availability and network flexibility are improved, but capability conflicts occur between radio resources leading to data transmission delays
Solution Approach 1:
The UE proactively identifies capability conflicts between radio resources of the first and second networks before they cause data transmission delays. By detecting the conflict in advance and autonomously disabling the first radio resource, the system prevents the delay from occurring, thus maintaining both multi-network flexibility and timely data transmission
Solution Approach 2:
The UE autonomously resolves the capability conflict without requiring external intervention from the networks. The UE independently detects the conflict between first and second radio resources, disables the conflicting first resource, and transmits disable information to the first network, enabling self-service conflict resolution that maintains operational flexibility while preventing transmission delays
2Productivity
If the UE autonomously disables the first radio resource to resolve capability conflict, then data transmission delays are reduced, but the device complexity increases due to autonomous conflict detection and management
Solution Approach 1:
The UE is equipped with autonomous capability to detect capability conflicts between radio resources and resolve them by disabling the conflicting first resource. This self-service mechanism eliminates data transmission delays caused by conflicts while integrating the conflict management functions directly into the UE's existing resource management architecture, avoiding excessive complexity increase
3Reliability
If the UE proactively resolves capability conflict before service initiation, then the reliability of communication is improved, but the loss of time for resource disabling and notification occurs
Solution Approach 1:
The UE detects capability conflicts between first and second radio resources before data transmission begins and autonomously disables the first resource in advance. This preliminary resolution ensures high communication reliability by preventing conflicts during active transmission, while the disabling time is minimized by performing the action only when conflicts are detected, not continuously

AI summary
The present disclosure relates to conflict resolution in wireless communications. According to an embodiment of the present disclosure, a method performed by a user equipment (UE) in a wireless communication system comprises: establishing a connection with a first network; detecting an event of establishing a connection with a second network while establishing the connection with the first network; after detecting the event of establishing the connection with the second network, identifying a capability conflict between a first resource used in the first network and a second resource for use in the second network; autonomously disabling the first resource based on identifying the capability conflict; and transmitting, to the first network, disable information related to disabling the first resource.
