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.
