Cloud Cell Base Station Data Scheduling During Handover

The patent applies preliminary action by detecting the master BS change and forwarding buffered data from the old master BS to the new master BS before the tunnel between the new master BS and access gateway is activated. This ensures that data is already available at the new master BS when the tunnel becomes active, eliminating unnecessary data forwarding operations and reducing latency while maintaining continuous service provision to the MS.

The patent implements feedback by having the new master BS detect when a master BS change occurs and monitor the tunnel activation status between itself and the access gateway. Based on this feedback information, the new master BS determines the appropriate timing to request and receive buffered data from the old master BS, enabling efficient data forwarding without excessive complexity through intelligent, condition-based scheduling decisions.

The patent applies self-service by enabling the new master BS to autonomously detect master BS changes and independently manage the data forwarding process from the old master BS. The new master BS automatically monitors tunnel activation status, determines when buffered data should be transferred, and executes the data reception and scheduling without requiring complex centralized control, thereby reducing system control complexity while optimizing data scheduling timing.
