Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UE connects to multiple networks with one SIM or Multiple-SIMs, then the UE can access more network services and increase connectivity, but the coordination of leaving procedures among multiple networks becomes complex and unclear
Solution Approach 1:
The patent segments the leaving procedure into distinct types (e.g., immediate leaving, delayed leaving, conditional leaving) based on different scenarios. Each leaving type has specific trigger conditions and execution procedures, breaking down the complex coordination problem into manageable, scenario-specific segments that can be handled independently.
Solution Approach 2:
The patent introduces preliminary actions such as sending leaving indication messages to networks before actual disconnection, configuring leaving parameters in advance, and establishing leaving priorities among multiple networks. These preliminary actions prepare the system for smooth transitions and reduce the complexity of real-time coordination.
2Productivity
If detailed leaving procedures are defined for multiple network scenarios, then the system can provide efficient wireless communication, but the configuration and coordination details remain unclear and complex
Solution Approach 1:
The patent creates a universal leaving procedure framework that can be applied across multiple network scenarios and types. The framework uses common message structures, standardized leaving types, and unified coordination mechanisms that work regardless of the specific network combination, reducing the need for scenario-specific configurations.
Solution Approach 2:
The patent utilizes parameter changes to manage leaving procedures dynamically. Different leaving parameters (such as leaving cause, leaving time, leaving priority) are adjusted based on the specific scenario, allowing the system to maintain high efficiency without requiring complex hard-coded procedures for each case.
3Reliability
If the UE determines leaving type based on particular scenarios, then the leaving procedure can be optimized for each scenario, but the determination and coordination process becomes more complex
Solution Approach 1:
The patent enables the UE to autonomously determine the appropriate leaving type based on pre-configured scenario rules and current network states. The UE self-evaluates its situation against defined criteria (such as service priorities, network types, and connection states) and selects the leaving type without requiring complex real-time coordination with all networks, simplifying the determination process while maintaining reliability.

AI summary
Methods, systems and devices for configuring signal resource for coordinating leaving procedures for one or more devices including multiple subscriber identity modules (Multi-SIMs) or for one or more devices connecting multiple networks with one subscriber identity module (SIM) are described. One method includes performing, by a user equipment (UE) corresponding to multiple networks, sending a mobile terminated (MT) filter assistance information by: determining, by the UE, the MT filter assistance information; and sending, by the UE, the MT filter assistance information to a network. Another method includes receiving, by a UE including Multi-SIMs corresponding to multiple radio access networks (RANs), a paging message from a RAN of the multiple RANs, wherein the paging message comprises a first indication indicating a paging cause; and the paging message comprises a second indication indicating whether the paging cause is supported in the paging message.
