Mitigating handover issues for ground-aerial hybrid networks
Abstract:
In modern networks, frequent handovers (e.g., ping-pong) from one AP device to another is a situation that can lead to increased latency, excessive resource utilization, poor quality of service, or radio link failure (RLF). Conventional networks employ mobility robustness optimization (MRO) procedures to balance tradeoffs between setting low thresholds before initiating a handover procedure, thereby increasing the likelihood of ping-pong issues, and setting those thresholds to higher values, thereby increasing the likelihood of RLF. Conventional MRO procedures are tailored to terrestrial-only networks and furthermore merely react to existing issues. Hybrid networks, having both terrestrial and aerial AP devices often witness ping-pong issues and may be implemented with urgency not conducive to using MRO procedures. An architecture is presented that can predict and mitigate ping-pong and other issues in connection with hybrid networks before those issues occur.
