Device-Driven eSIM Switching for Terrestrial-Satellite Network Mobility

The patent segments the communication networks into separate terrestrial and non-terrestrial systems, each operating independently with distinct network entities. The terrestrial network includes terrestrial base stations and core network elements, while the non-terrestrial network includes satellite platforms and associated control entities. This segmentation allows spectrum sharing through coordinated resource allocation without requiring full integration, thus improving spectrum utilization while maintaining manageable system complexity through modular architecture.

The patent implements preliminary action through pre-configured resource allocation patterns and pre-established handover protocols between terrestrial and non-terrestrial networks. Network entities maintain pre-defined resource pools and coordination mechanisms that are prepared in advance, allowing rapid switching and seamless coverage extension without requiring complex real-time negotiations. This reduces operational overhead by eliminating the need for extensive runtime coordination while maintaining expanded network coverage.

The patent implements universality by designing the non-terrestrial network entities (satellite platforms, aerial vehicles) to function as multi-functional communication nodes that can operate independently or in coordination with terrestrial networks. These universal communication entities can provide services across multiple network types and geographic regions, enabling resource-efficient spectrum sharing while maintaining scalability. The modular universal entities can be deployed independently or scaled incrementally without requiring proportional integration of entire terrestrial network infrastructures.
