Abstract

Handover is provided between a moving satellite terminal communicating via satellite with a destination node in a terrestrial network. Internet connectivity is provided between the satellite terminal and the destination node via an access gateway function (AGF). Embodiments provide transfer of an active PDU session such as voice or streaming over the internet protocol (IP) between a source AGF and a target AGF. Embodiments enable an AGF to understand when it needs to handover, where it needs to handover to and the protocol messages to achieve the handover.

Abstract

A satellite terminal satellite exchanges data with a 5G core network of a cellular wireless network by obtaining an internet protocol (IP) address using a router or switch and a gateway. The IP address is obtained using dynamic host configuration protocol (DHCP). The router or switch and the gateway are positioned between a satellite teleport and the core network. The data is sent as packets with the IP address being the source address of the satellite terminal. As such, a legacy satellite terminal, with addition of a DHCP client, is able to access services of the 5G core network.
