A method for entering a power saving mode of a terminal includes a first operation for starting a first timer after transmitting an idle mode request message; a second operation for, when an idle mode approval message is not received until the first timer expires, checking whether a number of retransmissions of the idle mode request message exceeds a number of allowed retransmissions of the idle mode request message; a third operation for, when the number of the retransmissions of the idle mode request message exceeds the number of the allowed retransmissions of the idle mode request message, increasing a number of idle mode entry failures; and a fourth operation for, when the increased number of the idle mode entry failures is greater than N times, entering a power saving mode which powers off a modem. | 02-26-2009 |
| 20090067404 | APPARATUS AND METHOD FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM - 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. | 03-12-2009 |

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. | 04-02-2009 |
| 20090104910 | APPARATUS AND METHOD FOR PROCESSING HANDOVER IN A WIRELESS COMMUNICATION SYSTEM - An apparatus and method for processing handover in a wireless communication system are provided. The method includes selecting a cell for handover when a HandOver (HO) drop occurs, identifying if information for communicating with a serving BS is stored, transmitting a message ranging request signal to the serving BS, identifying provision or non-provision of a service from the serving BS comprised in a response signal to the message ranging request signal, and transmitting/receiving a signal with the serving BS. | 04-23-2009 |
| 20090125775 | Method and apparatus for Automatic Repeat reQuest (ARQ) in broadband wireless access system - An apparatus and a method for Automatic Repeat reQuest (ARQ) in a broadband wireless access system are provided. The method includes driving a timer which operates by a preset period to synchronize ARQ between the transmitter and a receiver; after transmitting data to the receiver without error, when a driving time of the timer expires, checking whether there is data to transmit to the receiver; when there is no data to transmit to the receiver, initializing the timer; and transmitting an ARQ reset message to the receiver. Hence, the air resource consumption and the power consumption in ARQ reset can be lowered by reducing unnecessary ARQ reset. | 05-14-2009 |
| 20090139746 | Substrate panel - A substrate panel is disclosed. The substrate panel may include a clamp contact, a bus line formed at a distance from the clamp contact, and a plurality of substrate units supplied with an electric current by way of the bus line, where an insulation part may be formed between the clamp contact and the bus line, through which electricity may not flow. | 06-04-2009 |
| 20090139747 | Substrate panel - A substrate panel is disclosed. The substrate panel may include a pair of clamp contacts, a plurality of bus lines located between the pair of clamp contacts, and a plurality of substrate units supplied with an electric current by way of the plurality of bus lines, where the bus lines closer to the proximal clamp contact are arranged with larger intervals. | 06-04-2009 |
| 20100162022 | Apparatus and method for supporting selective suspend mode of USB network-device - 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 (D | 06-24-2010 |
| 20100306788 | Apparatus and method for supporting suspend of composite network device - An apparatus and a method support a selective suspend mode in a driver for any one of at least two devices constituting a composite network device. When a device of the driver requests suspend mode transition, a Physical Device Object (PDO) constituting a driver of the composite network device is identified by a PDO check part. A suspend mode transition request information of the device is sent to an operating system through the PDO. When the operating system allows the suspend mode transition, a control part sends suspend mode transition indication information to the device through the PDO. | 12-02-2010 |
| 20110032834 | Method and apparatus for transmitting and receiving service in a wireless communication system - A method and apparatus transmits and receives a service in a wireless communication system by acquiring Quality of Service (QoS) information. A packet is received through a direct communication with a terminal equipment providing a service. When the received packet includes a new destination Internet Protocol (IP) address different from a previously received packet, one or more service quality identifiers corresponding to the received packet are identified. The identified service quality identifiers are transmitted to the terminal equipment, and a service quality identifier corresponding to a service category selected by a user from the identified service categories is received from the terminal equipment. QoS information corresponding to the received service quality identifier is determined and used to generate a radio link between the mobile equipment and a mobile communication network. And the service is received through the radio link. | 02-10-2011 |
| 20110058561 | Apparatus and method for transmitting/receiving packet in dual modem mobile communication terminal - An apparatus and a method for transmitting/receiving a packet in a dual modem mobile communication terminal support data communication using both a host modem and a slave modem by additionally driving the slave modem when packet traffic is heavy. In the method for transmitting/receiving, at a host modem, a packet in a mobile communication terminal that includes the host modem and a slave modem, when a packet is received under a state where only the host modem is driven, it is determined whether a buffer count of the host modem is greater than a reference value. When the buffer count of the host modem is greater than the reference value, the slave modem is additionally driven and the received packet is provided to the slave modem. | 03-10-2011 |
| 20110116459 | Dual-modem mobile equipment and communication method using the same - A communication method uses a dual-modem Mobile Equipment (ME) that includes a cellular modem communicable with a cellular system and a Wireless Local Area Network (WLAN) modem capable of WLAN communication. The method includes registering a Media Access Control (MAC) address of a Terminal Equipment (TE) connected to the cellular modem over a WLAN. The method also includes receiving data from the TE with the registered MAC address at the WLAN modem through a WLAN interface, and transferring the data to the cellular system through the cellular modem. Thus, even a TE with no cellular modem equipped can perform data communication over the cellular network and the pre-registered TE is allowed to transmit and receive data through an ME with a WLAN modem, facilitating efficient use of the limited resources, and the user is allowed to set priorities of TEs, making it possible to ensure QoS of each TE independently. | 05-19-2011 |
