摘要： Disclosed are an apparatus for and a method of managing the location of a packet call in the wireless environment of a wireless packet data system. A dormant-state mobile station management is carried out by registering call information in a dormant state database in response to an initial request for a packet data service, registering dormant state information in a pointer lookup table, and updating location information of a mobile station entering a dormant state, based on the dormant state information, in response to a message received from the mobile station, or resuming the packet data service. In accordance with the invention, it is possible to reduce the connection time and load required to resume a call establishment associated with the mobile station maintained in a dormant state.

摘要： A wireless packet data system efficiently manages a location of a packet call in a radio environment. A mobile station transmits a location registration message to a target BSC when moving to the target BSC adjacent to a source BSC. Upon receipt of the location registration message, the target BSC transmits a location update message for updating a location of the mobile station to a centralized database. Upon receipt of the location update message, the centralized database updates dormant state information for the mobile station to connect the target BSC to the source BSC. The centralized database transmits a location update result message indicating complete update of the dormant state information to the target BSC.

摘要： There is provided a data transmitting method in a CDMA system. In the CDMA system, a control hold state and an active state are set for data transmission between a mobile station and a base station. The control hold state is entered to transmit a control signal on a dedicated control channel and the active state is divided into a low rate transmission substate for transmitting a small amount of data on the dedicated control channel or/and a fundamental channel and a high rate transmission substate for transmitting a large amount of data on a supplemental channel and on at least one of the dedicated control channel and the fundamental channel. When a large amount of user data is generated in the mobile station, the mobile station generates a supplemental channel request message including supplemental channel request information needed to transit from the control hold state to the high rate transmission substate without interposition of the low rate transmission substate and state transition information needed to transit from the control hold state to the active state, and transmits the supplemental channel request message to the base station.

摘要： Disclosed is a method for handing-off a mobile station receiving packet data over a second channel from a first base station system (BSS) to a second BSS by a base station controller (BSC) in a system in which the mobile station communicates with the first BSS and the second BSS adjacent to the first BSS through a first channel for transmitting a control message, and the mobile station communicates with the first BSS through the second channel for transmitting the packet data. In the method, the mobile station measures receiving strengths of pilot channels transmitted from the first BSS and the second BSS, and transmits the measured receiving strengths to the BSC through the first BSS and the second BSS. The first and second BSSs each calculate available transmission power allocable to the second channel and transmits the calculated available transmission power to the BSC. The BSC calculates a sum of the available transmission power and the measured receiving strength of the pilot channel from the first BSS and a sum of the available transmission power and the measured receiving strength of the pilot channel from the second BSS. The BSC transmits a handoff indication message to the second BSS, when the sum of the available transmission power and the measured receiving strength of the pilot channel from the second BSS is higher than the sum of the available transmission power and the measured receiving strength of the pilot channel from the first BSS.

摘要： A multi-channel scheduling method in a wireless network is provided. The wireless network includes a plurality of Wireless Local Area Network (WLAN) device with a single radio interface. A regular time interval P and a Channel Coordination Window (CCW) to be repeated in a period of P are set. A request is made such that the plurality of devices are tuned to a first channel at a start point of the CCW. A pair of arbitrary WLAN devices among the plurality of WLAN devices is allowed to transmit control frames in the regular time interval P. The control frames are a transmission proposal control frame for proposing communication in a second channel and a response frame, responding to the transmission proposal control frame, for indicating whether the second channel has been accepted or rejected. The arbitrary WLAN device of the pair are switched to the second channel after acceptance.
