Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional RRC state management is used during UE mobility, then device complexity is reduced, but service continuity is disrupted
Solution Approach 1:
The patent implements dynamic RRC state transitions, allowing the UE to flexibly switch between RRC_IDLE and RRC_INACTIVE states based on mobility conditions and service requirements. This dynamic adaptation enables seamless multicast broadcast service continuity during handovers while optimizing resource utilization and reducing unnecessary state management complexity.
Solution Approach 2:
The patent performs preliminary actions by establishing RRC_INACTIVE state configurations and preparing context information before actual handover occurs. This advance preparation ensures that when mobility events trigger state transitions, the UE can quickly resume services without disruption, thereby improving service continuity while managing complexity through pre-computed configurations.
2Productivity
If RRC Inactive State is utilized for optimized resource allocation, then resource utilization is improved, but service disruption risk increases
Solution Approach 1:
The patent dynamically manages RRC state transitions between RRC_IDLE and RRC_INACTIVE based on real-time service requirements and mobility conditions. This dynamic approach allows the system to optimize resource utilization by placing UEs in RRC_INACTIVE state when appropriate, while ensuring service continuity through rapid state resumption capabilities when services need to be maintained.
Solution Approach 2:
The patent changes key parameters including RRC state configurations, suspension/resumption conditions, and context information storage parameters to enable efficient transitions between RRC_IDLE and RRC_INACTIVE states. These parameter changes allow optimized resource allocation while maintaining service continuity by carefully controlling when and how state transitions occur.

AI summary
A system, method and apparatus for mobile communications including is provided. A user equipment (UE) receives measurement configuration parameters including one or more first measurement configuration parameters for handover decisions associated with one or more first services, the one or more first services associated with a first type of service and one or more second measurement configuration parameters for handover decisions associated with one or more second services. The first services are associated with a first type of service and the second services are associated with a second type of service. The UE transmits one or more measurement reports that include the two types of measurement information. The UE then receives a radio resource control (RRC) reconfiguration message indicating a handover to the target cell and establishes a connection with the target cell based on the received the RRC reconfiguration message.
