Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure is to provide a multicast service in a wireless communication system and comprises the steps of: receiving a multicast group participation message transmitted from a terminal via a communication session from a terminal to a first network entity; generating a multicast tunnel generation request message on the basis of the multicast group participation message, and transmitting the same to the first network entity; and generating a multicast service request message on the basis of the multicast group participation message, and transmitting the same to a second network entity. The present research is research that has been conducted with the support of the “Cross-Departmental Giga KOREA Project” funded by the government (the Ministry of Science and ICT) in 2017 (No. GK17N0100, millimeter wave 5G mobile communication system development).
