Innovation Solution
A method and apparatus for user equipment (UE) to determine the operating mode based on user input and SIM association, allowing selective activation or deactivation of SIMs to maintain optimal network performance, either in multi-SIM or single-SIM modes, ensuring seamless communication by prioritizing stable connections and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SIMs are activated simultaneously in non-standalone mode, then the device can support more network operators and provide greater versatility, but connection stability deteriorates and throughput decreases
Solution Approach 1:
The system dynamically adjusts SIM activation status based on real-time network conditions and user preferences. The UE can switch between multi-SIM and single-SIM modes, activate or deactivate specific SIMs, and reconfigure operational parameters to optimize performance under varying conditions, thereby maintaining connection stability while preserving versatility.
Solution Approach 2:
The patent modifies operational parameters such as SIM activation state, mode configuration (multi-SIM/single-SIM), and network selection criteria to balance versatility and connection stability. By changing these parameters based on network conditions and user input, the system achieves optimal performance without sacrificing either capability.
2Adaptability or versatility
If multiple SIMs are activated simultaneously, then device versatility improves, but throughput is reduced
Solution Approach 1:
The system dynamically configures SIM activation based on current network conditions and data traffic requirements. When high throughput is needed, the system can deactivate secondary SIMs or switch to single-SIM mode; when versatility is prioritized, multiple SIMs remain active. This dynamic adjustment optimizes throughput while preserving the ability to support multiple operators.
Solution Approach 2:
The patent changes operational parameters including SIM activation status and mode configuration to optimize throughput. By adjusting these parameters based on network conditions and user preferences, the system achieves high data rates when needed while maintaining the capability to operate with multiple SIMs for versatility.
3Adaptability or versatility
If non-standalone mode is used with multiple SIMs, then network coverage is expanded, but device complexity increases
Solution Approach 1:
The UE autonomously manages SIM activation and mode configuration by monitoring network conditions and automatically making decisions about which SIM to activate or deactivate. This self-service approach reduces the need for complex user intervention and manual configuration, thereby managing device complexity while maintaining network mode flexibility.
Solution Approach 2:
The system dynamically adjusts SIM management based on real-time conditions, automatically switching between modes and activating/deactivating SIMs as needed. This dynamic self-adjustment simplifies the user experience and reduces perceived complexity while expanding network coverage and maintaining flexibility.
4Ease of operation
If secondary SIM activation is enabled, then user choice is improved, but connection stability deteriorates
Solution Approach 1:
The system provides dynamic SIM activation controls that adapt to user preferences and network conditions. Users can choose to activate multiple SIMs for flexibility, and the system automatically adjusts configuration to maintain connection stability. When stability is compromised, the system can deactivate secondary SIMs or adjust modes to preserve reliable connections while still offering user choice.
Solution Approach 2:
The patent changes operational parameters such as SIM activation status and mode configuration to balance user choice with connection stability. By adjusting these parameters based on network conditions and user input, the system maintains reliable connections while preserving user flexibility and choice.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT, and that a second SIM has been activated for the UE. The UE may determine, based at least in part on user input, whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or to operate in a single SIM mode where only the first SIM, and not the second SIM, is active. The UE may selectively deactivate the second SIM based at least in part on determining whether to operate in the multi-SIM mode or the single SIM mode. Numerous other aspects are provided.
