Network selection in a non-terrestrial network

A processor of a user equipment (UE) configured to perform operations comprising:

• receiving broadcast information from a public land mobile network (PLMN) including at least a PLMN identifier (ID);
• attempting a registration with the PLMN by sending a registration request to the PLMN, wherein the UE attempts the registration via a base station operated by the PLMN deployed in a non-terrestrial network (NTN) arrangement including a non-terrestrial component configured to provide services to the UE via a service link;
• receiving a registration reject including a cause code indicating the PLMN is not allowed to operate at a current UE location;
• determining further conditions wherein the registration with the PLMN is not allowed, wherein the further conditions are determined based on default geographical information defining an area within which the UE should not attempt the further registration attempts;
• and
• avoiding further registration attempts with the PLMN when the further conditions are met.

• receiving a registration request for the PLMN from the UE;
• determining a current UE location;
• determining the PLMN is not allowed to operate at the current UE location;
• and
• transmitting a message to the UE including a cause code indicating the PLMN is not allowed to operate at the current UE location.
