Abstract
A system and a method for directing a handover of communications in Radio Frequency (RF) networks at a UT. The method includes servicing a user terminal (UT) via a first network having a first coverage area; receiving, from the UT via the first network, a measurement report for a second network having a second coverage area based on a measurement configuration of the second network; sending, to the UT via the first network, a handover order for obtaining service from the second network; and establishing, via a second network RAN (radio access network), a service for the UT via the second network per the handover order. In the method, the first network may include either a terrestrial network (TN) or a non-terrestrial network (NTN), the second network may include other of the TN or the NTN, and the TN and the NTN are RF networks. In the method, the establishing is performed while the UT is disposed in an overlap area of the first coverage area and the second coverage area, and the measurement report may include a RF signal metric of the second network at the UT.
