1. A method performed by a terminal in a communication system, the method comprising:
identifying a protocol data unit (PDU) session to be established as an always-on PDU session based on an indication from an upper layer;
transmitting, to a network entity, a PDU session establishment request message including first information for requesting to establish the PDU session as the always-on PDU session;
identifying whether a user-plane resource for the always-on PDU session is established, the always-on PDU session being established based on the PDU session establishment request message; and
transmitting, to the network entity, a service request message associated with a change of a 5G system (5GS) mobility management (5GMM) mode, in case that the user-plane resource for the always-on PDU session is not established,
wherein the service request message includes uplink data status information indicating the always-on PDU session for which data is pending.
