Abstract: In a cellar system providing various packet services, sleep mode operation of a terminal in an idle state is controlled. The cellular system determines a discontinuous receiving (DRX) period according to a QoS of a packet service provided to the terminal, and runs the sleep mode according to the determined DRX period. The cellular system runs the sleep mode divided into shallow sleep duration and deep sleep duration. With this manner, a paging delay to the terminal and a power consumption of the terminal may be reduced.

Abstract: A preamble allocation method and a random access method in a mobile communication system are provided to prevent an unnecessary collusion and a delay of a processing time by using a preamble resource allocated to a corresponding mobile station. A preamble allocation method in a mobile communication system includes the steps of: dividing a preamble resource into a competition based group and a reservation allocation group; dividing the preamble resource into a competition based region for transmitting the preamble based on the preamble resource corresponding to the competition based group, and a reservation allocation region for transmitting the preamble based on the preamble resource corresponding to the reservation allocation group; broadcasting the preamble configuration information for the preamble resource which is divided into the competition based group and the reservation allocation group; and allocating the preamble resource of the reservation allocation group to a predetermined mobile station.

Abstract: A radio resource allocation method in a mobile communication system is provided to recover radio resources temporarily if a transmission packet does not exist, so that the recovered resources can be newly allocated to another mobile terminal, thereby efficiently operating resource allocation, recovery, and reallocation according to existence of the packet. If a downlink packet does not exist for the first mobile terminal assigned with downlink radio resources, the assigned radio resources are recovered and assigned to the second mobile terminal. It is continuously confirmed whether a new downlink packet exists for the first mobile terminal whose radio resources are recovered. If so, the radio resources assigned to the second terminal are recovered and reassigned to the first terminal.
