Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks face challenges in efficiently enabling user equipment to simultaneously connect to different networks with different network identifier information, leading to inefficiencies and resource wastage due to unsupported dual or multiple steering scenarios.
Innovation Solution
A method where user equipment transmits capability indication information to network entities, receiving multiple registration information to ensure dual or multiple steering is applied only where conditions are met, using a single set of credentials and avoiding unnecessary attempts in unsupported scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user equipment attempts to simultaneously connect to multiple mobile communication networks with different network identifier information, then connectivity versatility is improved, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent introduces a capability indication information mechanism as an intermediary that mediates between the user equipment's dual connection capability and the network's support status. This intermediary signal allows the network entity to inform the user equipment whether multiple network registration is supported, thereby managing the complexity of multi-network connectivity without compromising versatility.
Solution Approach 2:
The system dynamically adjusts the connectivity behavior based on network conditions and capability indications. The user equipment can adaptively enable or disable simultaneous connection to multiple networks depending on the received capability indication information, making the system flexible rather than statically complex.
2Adaptability or versatility
If user equipment supports dual steering functionality, then network connectivity options increase, but compatibility issues with legacy systems arise
Solution Approach 1:
The patent implements a feedback mechanism where the network entity sends capability indication information back to the user equipment regarding its support for multiple network registration. This feedback loop ensures that dual steering functionality is only activated when both the user equipment and the network mutually support it, thereby maintaining compatibility with legacy systems while enabling advanced connectivity options where available.
3Speed
If user equipment attempts multiple network registration without capability indication, then connectivity speed is improved, but network resource waste increases
Solution Approach 1:
The patent applies preliminary action by having the user equipment transmit capability indication information before attempting multiple network registration. The network entity uses this advance information to determine whether to support simultaneous registration, preventing unnecessary registration attempts and avoiding waste of network resources while still enabling fast connectivity when supported.
4Reliability
If user equipment simultaneously registers to multiple networks, then service availability is improved, but authentication and credential management complexity increases
Solution Approach 1:
The patent enables the user equipment to use a single set of credentials for authentication across multiple mobile communication networks. This universal authentication approach allows simultaneous registration to multiple networks (improving service availability) while avoiding the complexity of managing separate credentials for each network.
