Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently updating user equipment (UE) configurations, particularly in managing access and mobility-related parameters, which limits network flexibility and adaptability to changing conditions.
Innovation Solution
A method for updating UE configurations by determining the need for parameter updates and transmitting corresponding commands, allowing the UE to initiate registration procedures based on mode (CONNECTED or idle) and parameter type, enabling flexible configuration adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network updates UE configuration parameters through traditional methods, then configuration changes can be made, but the network flexibility and adaptability to changing conditions are limited
Solution Approach 1:
The patent implements dynamic configuration update by allowing the network to send UE configuration update commands that can modify parameters without requiring full re-registration. The UE can transition between connected and idle modes dynamically, and the network can update parameters such as access and mobility settings on-demand based on current network conditions and UE behavior patterns.
Solution Approach 2:
The configuration update mechanism is segmented into specific parameter updates rather than complete reconfiguration. The network can update individual parameters (e.g., access parameters, mobility parameters) independently through targeted commands, reducing the overall complexity while maintaining flexibility to modify only necessary parameters.
2Reliability
If the UE performs registration procedure for every parameter update, then configuration accuracy is maintained, but signaling overhead and network load increase
Solution Approach 1:
The patent applies partial action by updating only specific configuration parameters that need modification rather than performing complete re-registration. The network sends targeted UE configuration update commands for specific parameters (e.g., access parameters, mobility parameters) while leaving other parameters unchanged, thereby maintaining configuration accuracy for updated parameters while reducing overall signaling overhead.
Solution Approach 2:
The network performs preliminary assessment to determine which parameters need updating before initiating configuration changes. This preliminary action allows the network to prepare targeted update commands only for necessary parameters, avoiding unnecessary full re-registration procedures and reducing signaling overhead while maintaining reliability.
3Speed
If the UE remains in CONNECTED mode for configuration updates, then update speed increases, but energy consumption increases
Solution Approach 1:
The patent implements dynamic mode selection where the UE can be in either connected or idle mode depending on the configuration update requirements. For urgent or critical parameter updates, the UE remains in connected mode enabling fast updates. For non-critical updates, the UE can transition to idle mode to conserve energy, with the network scheduling updates appropriately based on UE activity and power state.

AI summary
A UE configuration update method in a wireless communication system and an apparatus therefor are disclosed. Specifically, a method for updating a configuration of user equipment (UE) by an access and mobility management function (AMF) in a wireless communication system includes determining whether the configuration of the UE needs to be changed without a request of the UE and transmitting a UE configuration update command message to the UE when the configuration of the UE needs to be changed, wherein the UE configuration update command message includes an updated UE parameter.
