TERMINAL CACHING METHOD AND APPARATUS USING MULTICAST IN MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a terminal caching method using a multicast in a mobile communication system, and particularly, the method comprising the steps of: receiving, from a base station, a group-radio network temporary identifier (G-RNTI), a temporary identifier of a multicast mobile caching (MMC) group comprising a reader terminal and terminals which are interested in content corresponding to a service request transmitted by the reader terminal; receiving, from the base station, the scheduling information transmitted to the reader terminal in response to the service request through an overhearing method by using the G-RNTI; receiving, from the base station, multicast data transmitted to a resource region indicated by the scheduling information, wherein the reader terminal is a terminal, for transmitting the service request first to the base station, among a plurality of terminals which are interested in the content.
