Summary:
|
FMSC is the capability that provides services and applications to end users regardless of the fixed, mobile or satellite access technologies being used. The GSO overlay ensures continuous coverage, compensating for NGSO limitations (e.g., power-induced beam deactivation/gaps) and providing a reliable fallback during handover failures or device power-saving cycles. The connection fall back can provide a mechanism to let UEs primarily connect to GSO for minimal power use, and connection to NGSO satellites occurs only upon explicit network instruction. This Recommendation specifies the general considerations, requirements, framework, procedures and security considerations of Connection switching for FMSC, in the context of IMT-2020 networks and beyond.
