Converged Mobility Management Access Failure Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where both 2/3G and 4G networks overlap, user equipment frequently handovers between the two networks, leading to service interruptions and poor stability due to unsuccessful access attempts to the 4G network without subscription data, causing continuous access failures.
Innovation Solution
A converged mobility management network element counts continuous cumulative access failures and sends indication information to base stations to prevent the user equipment from accessing the 4G network when the failure count meets a preset condition, thereby improving service stability by avoiding frequent handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station preferentially connects user equipment to the 4G network in overlapping coverage areas, then network performance is improved, but service stability deteriorates due to frequent handovers and access failures
Solution Approach 1:
The mobility management network element implements a feedback mechanism by counting continuous access failures and sending indication information to the base station. When the failure count reaches a threshold, the system feedbacks the base station to stop preferential connection to the 4G network, thereby resolving the contradiction between network performance and service stability.
Solution Approach 2:
The system dynamically adjusts the base station's connection preference based on real-time access success rates. The indication information sent to the base station is dynamic, changing from 'prefer 4G' to 'stop preferring 4G' based on the continuous cumulative failure count, allowing the system to adapt to changing network conditions.
2Reliability
If the base station continuously attempts to connect user equipment to the 4G network, then access success rate may improve eventually, but service stability deteriorates due to frequent handovers and interruptions
Solution Approach 1:
The system takes preliminary anti-action by preventing continuous access attempts before service stability is severely compromised. When the continuous failure count reaches the threshold, the indication information is sent to the base station to stop preferential connection, thereby preventing further handover interruptions while preserving the ability to retry after a reset.
3Reliability
If the mobility management network element sends indication information to stop preferring the first network, then service stability is improved by reducing handovers, but network performance deteriorates due to reduced access opportunities
Solution Approach 1:
The system applies partial action by sending the indication information only when the continuous failure count reaches a specific threshold, not immediately upon the first failure. This partial intervention stops preferential connection only when necessary, preserving network performance while achieving service stability. The threshold-based approach ensures that the action is taken only when the problem is significant enough to warrant intervention.
