Satellite-Ground 5G Seamless Fusion Protocol SkyGround Approved by 3GPP
3GPP formally approves SkyGround protocol enabling seamless handover between satellite internet and terrestrial 5G networks, keeping users connected during flight, ocean voyages, or in remote areas without manual network switching.
International mobile communications standards body 3GPP today formally approved the SkyGround protocol, defining standards for seamless handover between satellite internet and terrestrial 5G networks. Devices supporting this protocol can automatically switch between ground base station coverage and satellite coverage without users perceiving any network interruption.
SkyGround's core is a "predictive handover" mechanism. Devices use GPS position, speed, and direction to predict when users will enter satellite coverage areas, pre-establishing satellite link connections. The handover completes within 50 milliseconds — below the human perception threshold.
SpaceX's Starlink, Amazon's Kuiper, and China's SatNet have announced SkyGround support. First smartphones supporting the protocol are expected in early 2030. SkyGround's approval is seen as a key milestone toward the vision of "global seamless connectivity."
