Electronic device for supporting non-terrestrial network and operation method thereof

A method of operating an electronic device, the method comprising:

• identifying, while connecting to a network through a node, whether the network comprising the node is the non-terrestrial network, based on system information received from the node;
• identifying, based on the network being the non-terrestrial network, services supported by the network, based on mapping data in which identification information of the non-terrestrial network and
• services supported by the non-terrestrial network are mapped;
• and
• prohibiting transmission of a request message for establishment of a packet data unit (PDU) session for a service, which is not supported by the network, to the network;
• wherein the prohibiting of transmission of a request message for establishment of a packet data unit (PDU) session to the network comprises, based on the non-terrestrial network being a network that supports only a short message service (SMS) and
• a multimedia messaging service (MMS), prohibiting transmitting, to the non-terrestrial network, requests for establishment of sessions other than the session for transmitting data related to the MMS between the electronic device and the non-terrestrial network.
