The patent application (Publication Number: US20240040448A1) describes a method for maintaining radio connectivity and 5G service of user equipment (UE) during the transfer from a 4G technology base station to a target base station connected to a 5G technology base station on a dual-connected mobile technology platform. The method involves steps such as measuring signal quality of source eNodeB neighbors, selecting a target eNodeB for handover, activating the UE handover procedure, determining the ability to support Enhanced Network Data Connection (ENDC), choosing a gNodeB station, and conducting the sgnb addition procedure with the target gNodeB. The process ensures a seamless transition for the UE while moving between different generations of technology, maintaining connectivity and service quality.

The method outlined in the patent application involves detailed steps for ensuring a smooth handover process for the UE from 4G to 5G technology base stations. By measuring signal quality, selecting appropriate target stations, and verifying the ability to support ENDC and 5G technology, the method aims to optimize the connectivity and service experience for the UE. The process also includes steps for selecting the best 5G station for connection, conducting the sgnb addition procedure with the target gNodeB, and ensuring a successful transition to the new network. Overall, the method described in the patent application addresses the challenges associated with transitioning between different generations of technology while maintaining radio connectivity and service quality for user equipment.
