MICO Mode Registration Timer Control for 5G UE Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks, particularly in 5G systems, face challenges in efficiently managing the Mobile Initiated Connection Only (MICO) mode, which affects the mobility framework and connection management.
Innovation Solution
A method is introduced that involves a UE (User Equipment) requesting registration with a preferred MICO mode and suggested duration, which is then determined by an AMF (Access and Mobility Management Function) based on communication patterns. The AMF transmits a determination and a periodic registration update timer value to the UE, allowing it to perform registration updates accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the UE operates in MICO mode to reduce power consumption and limit reachability, then energy efficiency is improved, but network control and monitoring capability deteriorates
Solution Approach 1:
The patent implements periodic registration updates where the UE transitions to connected state at regular intervals defined by a periodic registration update timer. This allows the network to periodically regain control and monitoring capability while the UE remains in idle state for extended periods, achieving a balance between power savings and network control.
2Reliability
If the UE frequently updates registration to maintain network reachability, then network control capability is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts the periodic registration update timer value based on network policies and UE behavior. The timer can be modified by the network to optimize the balance between reachability and power consumption, allowing the system to adapt to different operational scenarios rather than using fixed update intervals.
3Speed
If the network maintains continuous connection to ensure immediate service delivery, then service responsiveness is improved, but network resource consumption increases
Solution Approach 1:
The patent allows the network to prepare for potential service delivery by maintaining the ability to quickly transition the UE from idle to connected state through periodic registration updates. While the UE is in idle state saving resources, the network retains control information and can rapidly establish connection when service is needed, achieving a balance between resource efficiency and service responsiveness.
