Samsung patents phone logic to skip voice search on satellite networks
This patent describes a method for phones to connect to satellite networks when regular cell towers are unavailable. The system checks if the satellite network supports voice calls and, if not, skips the usual search for voice services to speed up the connection process.
In the filing’s own words
A method performed by a User Equipment (UE) for handling a Non-Terrestrial Network (NTN) connection, includes: detecting at least one of: a presence of the UE in an NTN only coverage area, or a non-availability of a Terrestrial Network (TN) coverage at a location of the UE; determining an availability of an NTN; selecting the NTN for a registration of the UE; determining an absence of a voice-service support from the selected NTN, wherein the absence of the voice-service support indicates that the selected NTN does not support a voice service for the UE; performing at least one control action to avoid searching for the voice service during the registration of the UE on the NTN; and completing the registration of the UE on the NTN, based on the performed at least one control action.
