Abstract
In a wireless mobile communications system, a network transmits a response request message with respect to a particular point-to-multipoint service to a terminal, the terminal transmits uplink access preamble according to information of the received response request message and receives a response message in response to the uplink access preamble. The terminal transmits an uplink message to a network if a terminal identifier together with an identifier of the preamble are included in the response message, and does not transmit the uplink message to the network if only the identifier of the preamble is included in the response message, thereby effectively utilizing uplink radio resources during the uplink access.
