AI Technical Summary
In radio communication systems, when a terminal suspended from connection attempts to reconnect through a different base station, the setup of an uplink connection can involve significant processing and signaling, leading to inefficiencies, especially for small data transmissions or low latency connections.
The proposed solution involves forwarding uplink data from the base station where the terminal initiates access to the base station maintaining the active interface for the terminal's connection, using the logical inter-node interface Xn in 5G or X2 in LTE, thereby avoiding a path switch and reducing latency.
This approach reduces signaling overhead, minimizes latency for small data transmissions, and conserves UE power by avoiding unnecessary path switches and RRC inactive reconfigurations.
