An apparatus and method for saving power of a USB composite network device is provided. The method includes sending an idle request IRP to a composite driver at a bus driver of a network driver when the composite network device requests selective suspend, sending power state transition information to the composite driver and shifting a power state from a normal state to an intermediate sleep state at the bus driver, and shifting a power state from the normal state to the intermediate sleep state at the composite driver according to the power state transition information, wherein, when the composite network device is shifted to the selective suspend mode, the bus driver and the composite driver are in the intermediate sleep state and an NDIS miniport driver of the network driver is in the normal state.

An apparatus and method for random access in a wireless communication system are provided. In the method, a random access response message is received. The random access response message is analyzed to determine a status of a random access process. A count variable value is updated according to the status. And the count variable value is compared with at least one reference value to determine a random access period. By adaptively changing the period of periodic ranging in a wireless communication system, the probability of success is increased while the waste of resources is decreased.

A method for planning cells in a communication system and a method for scanning the power of a neighbor base station of the same system. With no need to set a separate scanning interval for measuring the power of a neighbor base station, a subscriber terminal measures the power in a section or duration of a data frame, received from a serving base station, in which there is no data allocated to the terminal. This increases transmission efficiency of the system. The terminal can also simultaneously demodulate broadcast channel information from two different base stations whose broadcast channels are differently located. This enables the terminal to communicate simultaneously with a plurality of base stations, and communicate with the serving base station while measuring the power of the neighbor base station.

A method for controlling a sleep mode in a wireless access communication system is disclosed. In the method, a base station and a subscriber terminal share a predetermined number of SI for a sleep mode control, and the base station sets a paging position by means of a predetermined BCID assigned to subscriber terminals and the SI, so that the base station can easily manage sleep intervals of the subscriber terminals. Further, since information for a sleep interval scheduling is not transmitted when the subscriber terminal shifts to a sleep mode, the amount of traffic between the subscriber terminal and the base station can be reduced.
摘要:
An apparatus and method for controlling a sleep mode in a wireless access communication system. The apparatus determines a predetermined number of groups for grouping at least one subscriber terminal according to type information of a paging interval equal to the sum of the sleep interval and the listening interval, and registers the subscriber terminal in one group from among the groups on the basis of the paging interval type of the subscriber terminal. Upon receipt of the group information, the apparatus controls a base station to pre-recognize a terminal woken up at a predetermined time from among a plurality of terminals entering the sleep mode, resulting in reduction of the number of unnecessary paging message transmissions and improved efficiency of the wireless access communication system.

Disclosed is a system and a method for provisioning service flows in broadband wireless access communication. In a broadband wireless access communication system, if a base station receives a registration request message from a mobile station, and if the base station inserts information about service flows to be provisioned by a base station into a registration response message and transmits the registration response message to the mobile station after the registration request message is received, the mobile station determines if the mobile station transits into a normal operation mode corresponding to the information and exactly recognizes a time point at which the mobile station goes into the normal operation mode.

A host computer equipment includes an apparatus configured to perform a method for supporting a selective suspend mode of a Universal Serial Bus (USB) network-device. The host includes a power manager, a status manager, and a USB driver. When there is a transition to a host suspend mode, the power manager delivers a host suspend mode notification message to the status manager. The status manager delivers a status transition message of instructing a normal status (D0) transition to the USB driver. The USB driver makes a power status of the USB network-device transit to a normal status (D0), notifies the power manager of the status transition to the normal status (D0), and makes the power status of the USB network-device transit from the normal status (D0) to a power off status (D3).

An apparatus and method for estimating UpLink (UL) transmission timing in a Mobile Station (MS) of a wireless communication system are provided. The method includes tracking DL timing by using a DL preamble signal received for each frame; estimating a time offset between a previous frame and a current frame by using the DL timing tracked for each frame; and estimating the UL transmission timing by using the estimated time offset.
