Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual-connectivity and multi-connectivity scenarios, user equipment (UE) faces challenges with inefficient mobility configuration management, leading to increased signaling overhead and potential communication failures due to incorrect target cell selection and poor quality.
Innovation Solution
The UE performs operations associated with both a first and second mobility configuration, retaining or deleting the second configuration as needed to minimize reconfiguration and reduce signaling overhead, thereby optimizing mobility operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE maintains both first mobility configuration and second mobility configuration simultaneously, then the UE can perform mobility operations more flexibly, but the signaling overhead increases and the risk of incorrect target cell selection increases
Solution Approach 1:
The patent extracts and removes the second mobility configuration from the UE when the first mobility configuration is determined to be sufficient. The network device monitors UE mobility performance and selectively deletes the second configuration to reduce signaling overhead while maintaining flexibility when needed. This selective extraction resolves the contradiction by dynamically adjusting configuration retention based on actual mobility requirements.
Solution Approach 2:
The patent implements dynamic mobility configuration management where the network device continuously monitors UE mobility patterns and adjusts the number of stored mobility configurations accordingly. When mobility conditions change, the network device can add or remove the second configuration dynamically. This dynamic adjustment allows the system to adapt between maintaining high flexibility and reducing signaling overhead based on real-time conditions.
2Adaptability or versatility
If the UE maintains both first mobility configuration and second mobility configuration simultaneously, then the UE can perform mobility operations more flexibly, but the risk of incorrect target cell selection increases
Solution Approach 1:
The patent implements a feedback mechanism where the network device monitors UE mobility performance and the accuracy of target cell selections. Based on this feedback, the network device determines whether to maintain or delete the second mobility configuration. When incorrect target cell selections are detected, the system feedback triggers removal of the second configuration, thereby improving reliability while preserving flexibility when the feedback indicates proper operation.
Solution Approach 2:
The patent applies beforehand cushioning by having the network device proactively monitor and assess the necessity of maintaining the second mobility configuration before potential access failures occur. The network device evaluates mobility patterns and predicts when having both configurations might lead to incorrect target cell selection, and preemptively removes the second configuration to prevent access failures rather than reacting after problems occur.
3Adaptability or versatility
If the network device sends both first mobility configuration and second mobility configuration to the UE, then the UE has more mobility options, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the UE to autonomously manage its mobility configurations based on network instructions. The UE stores the first mobility configuration permanently and conditionally stores the second configuration based on network directives. This self-service approach allows the UE to independently handle configuration retention and deletion, reducing the complexity burden on the network device while maintaining multiple mobility options when needed.
Solution Approach 2:
The patent segments the mobility configuration management into two distinct parts: the first mobility configuration which is always maintained, and the second mobility configuration which is conditionally maintained. This segmentation allows the system to manage complexity by treating different configuration types differently - the first configuration provides baseline flexibility while the second configuration adds optional enhancement that can be independently controlled and removed without affecting core mobility functionality.

AI summary
Embodiments of the present disclosure provide an information processing method and apparatus, a communication device, and a storage medium. The information processing method is executed by a user equipment (UE), and comprises: in response to executing a first operation associated with a first mobility configuration of a UE, executing a second operation associated with a second mobility configuration of the UE. The second mobility configuration of the UE is reserved, so that the UE can conveniently execute a mobility operation associated with the second mobility configuration, thereby reducing reconfigurations of the second mobility configuration, and reducing the overhead of signaling. After executing a mobility operation associated with the first mobility configuration, the UE deletes the second mobility configuration that is invalid due to first mobility associated with the first mobility configuration, thereby reducing storage space occupied by the invalid second mobility configuration, and reducing the access failure caused by selection of a wrong target cell according to continuous storage of the second mobility configuration being triggered and/or poor quality of communications after the access.
