UE Transfer Return Monitoring for PLMN Incompatibility Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ineffective transfer attempts to a target base station in cellular communications networks result in resource wastage and user experience disruptions due to PLMN incompatibility, leading to repetitive UE transfer failures.
Innovation Solution
Implementing a UE transfer return manager that monitors anomalous patterns of UE transfer returns to detect PLMN incompatibilities, recording such patterns as redirection restriction data to avoid subsequent transfer attempts to incompatible target base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the source base station attempts to transfer the UE to the target base station without monitoring transfer returns, then the transfer operation can be initiated quickly, but network resources are wasted due to repetitive ineffective transfer attempts caused by PLMN incompatibility
Solution Approach 1:
The system performs preliminary monitoring of UE transfer return patterns before initiating new transfer operations. By detecting anomalous cyclical patterns of repeated transfers and returns, the source base station can identify PLMN incompatibility issues in advance and prevent wasteful transfer attempts, thus maintaining quick operation initiation while avoiding network resource waste
Solution Approach 2:
The system implements a feedback mechanism where the source base station monitors whether UEs return to the source base station after being transferred to target base stations. This feedback information about transfer success/failure patterns is used to adjust future transfer decisions, preventing repetitive ineffective transfers while maintaining efficient transfer operations
2Reliability
If the source base station monitors and records UE transfer return patterns to detect PLMN incompatibility, then ineffective transfer attempts are prevented, but the system complexity increases due to additional monitoring and data management functions
Solution Approach 1:
The UE transfer return manager is designed to perform multiple functions: monitoring transfer returns, detecting anomalous patterns, determining PLMN incompatibility, and preventing future ineffective transfers. By consolidating these functions into a single multi-functional manager at the base station, the system achieves high transfer reliability without proportionally increasing overall system complexity
Solution Approach 2:
The base station automatically monitors its own transfer operations and uses the collected data to make autonomous decisions about preventing future ineffective transfers. The system self-manages the complexity of pattern recognition and decision-making without requiring external network management intervention, thereby improving reliability while containing complexity within the base station
3Adaptability or versatility
If repetitive UE transfer attempts are allowed without restriction, then the UE can continuously search for available PLMN access, but user experience is degraded due to connection failures and network resource consumption
Solution Approach 1:
The source base station applies preliminary anti-action by preventing transfer attempts to target base stations that have been identified as incompatible with the UE's home PLMN. By proactively blocking these ineffective transfers based on monitored return patterns, the system maintains UE adaptability to find available PLMN access while preventing user experience degradation from repeated connection failures

AI summary
Systems and methods for user equipment (UE) transfer return management are provided. In some embodiments, a telecommunications base station may include a UE transfer return manager that monitors when a UE transfers out to a target base station, and looks for anomalous patterns of UE transfer returns that may be indicative of a PLMN incompatibility. When the UE transfer return manager detects that a UE is exhibiting an anomalous cyclical pattern of transfer returns an incompatibility may be presumed between the UE and that target base station. The incompatibility may be recorded by the UE transfer return manager to memory as UE redirection restriction data. The UE redirection restriction data may then be referenced by the source base station to forgo subsequent attempts to transfer that UE to that target base station, thus avoiding the waste of network and/or UE resources being consumed by ineffective UE transfer attempts.
