摘要：
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system such as Long Term Evolution (LTE). A method of an access and mobility function (AMF) for state management in a wireless communication system is provided. The method comprises determining a state of at least one state machine, receiving, from a target access network (AN), an N2 path switch request message based on the state of the at least one state machine, transmitting, to a session management function (SMF), an N11 message, and transmitting, to the target AN, an N2 path switch request acknowledgement (Ack) message when receiving an N11 Ack message, from the SMF, corresponding to the N11 message, wherein the target AN transmits a release resource message to a source AN when the target AN receives the N2 path switch request Ack message.
