Abstract
The present disclosure relates to systems, methods, and computer-readable media for increasing resiliency in distributed units of a virtual radio access network (vRAN) of a telecommunications network (e.g., a 5G telecommunications network), particularly when performing a planned handover operation between the distributed units. The examples described herein specifically relate to implementing an inter-distributed unit handover between distributed units that are serviced by the same radio unit. In some examples, this handover is initiated by a middlebox entity that is positioned between the distributed units and a centralized unit. In some instances, features of the middlebox entity are implemented within the framework of a centralized unit. By allowing a quick handover as described herein, the distributed units can provide uninterrupted service to a UE while allowing the distributed units to perform various upgrades or modifications to the distributed unit without service interruptions.
