Engineering Contradiction Analysis
1Reliability
If data forwarding is implemented during layer 1 or layer 2 triggered mobility in dual connectivity scenarios, then mobility management performance is improved, but data forwarding efficiency deteriorates due to suboptimal resource utilization
Solution Approach 1:
The patent implements dynamic data forwarding mechanisms that adapt to layer 1 or layer 2 triggered mobility events. The system dynamically adjusts data forwarding paths and resource allocation based on real-time mobility conditions, allowing the network to optimize data flow during handover scenarios while maintaining reliable mobility management.
Solution Approach 2:
The patent establishes data forwarding tunnels and resource allocations in advance before mobility events occur. By pre-configuring data forwarding paths and reserving resources, the system ensures that data forwarding can continue efficiently during layer 1 or layer 2 triggered mobility without interruption or performance degradation.
2Productivity
If protocol stacks are optimized for dual connectivity scenarios, then network performance is improved, but system complexity increases
Solution Approach 1:
The patent segments the protocol stack into distinct functional modules, separating data forwarding functions from mobility management functions. This modular segmentation allows each component to be optimized independently for dual connectivity scenarios while maintaining overall system performance, without requiring complete redesign of the entire protocol stack.
Solution Approach 2:
The patent implements universal data forwarding mechanisms that function across multiple scenarios including layer 1 triggered mobility, layer 2 triggered mobility, and normal operation in dual connectivity. By creating multi-functional protocol elements that can adapt to different operational modes, the system achieves improved network performance without proportionally increasing complexity.
3Productivity
If resource allocation is optimized during mobility events, then resource utilization is improved, but processing time increases
Solution Approach 1:
The patent pre-allocates resources and establishes data forwarding tunnels before mobility events are triggered. By performing resource allocation in advance during normal operation, the system avoids time-consuming resource management operations during actual mobility events, thus improving resource utilization without significantly increasing processing time.
Solution Approach 2:
The patent implements self-service mechanisms where the system automatically manages data forwarding and resource allocation during mobility events without requiring extensive centralized processing. The distributed self-service approach reduces processing time by enabling local decision-making while still achieving optimized resource utilization across the network.

AI summary
A second base station sends, to a wireless device, a medium access control control element (MAC CE) triggering a layer 1 or layer 2 triggered mobility (LTM) cell switch from a SCG of the second base station to a cell of a SCG of a third base station. The second base station sends, to a first base station after sending the MAC CE, a notification message for the LTM cell switch, wherein the first base station is a master base station of the wireless device.
