1Area of stationary object
If non-terrestrial networks (NTN) are integrated into mobile communication systems, then service area is expanded, but transmission delay increases affecting mobility management and quality of service
Solution Approach 1:
The system performs preliminary actions by pre-configuring connection assistance information including delay characteristics before actual communication occurs. This allows the network to prepare mobility management parameters and quality of service settings in advance, compensating for the inherent transmission delays of NTN systems.
Solution Approach 2:
The invention changes system parameters by introducing delay indication information and connection assistance information that explicitly characterize NTN-specific parameters. This allows the network to adjust mobility management thresholds, handover timing, and resource allocation based on the known delay characteristics of non-terrestrial networks.
2Reliability
If connection assistance information is transmitted between entities, then mobility management and quality of service are improved, but device complexity increases
Solution Approach 1:
The connection assistance information message structure is designed to be universal and multi-functional, serving multiple purposes including mobility management, quality of service configuration, and delay compensation. This single message type handles various network scenarios (NTN, terrestrial, handover) without requiring separate complex signaling procedures for each case.
