Abstract: A method for transmitting downlink by a network node. The network node creates downlink data for a terminal which is in a radio resource control (RRC) idle state. The network node inserts the downlink data into a first paging message for transitioning the terminal to an RRC connected state, when a size of the downlink data is smaller than a reference value. In addition, the network node transmits the first paging message to the terminal through a base station.

Abstract: A method of providing a multicast service is provided by a terminal in a terminal-to-terminal direct communication. The terminal transmits a service start request message requesting a start of a multicast service to a multicast server, and receives a service start response message including a result of permitting a start request from the multicast server. The terminal receives, via a base station, resource information of a resource which a multicast coordinator allocates to the multicast service in accordance with a request of the multicast server, and transmits multicast service data based on the resource information.
