| 20100109943 | POSITION LOCATING METHOD AND SYSTEM USING SECURE USER PLANE LOCATION - A position locating method and system for locating a position of a mobile terminal using Secure User Plane Location (SUPL) are provided. A position locating method using Secure User Plane Location (SUPL) according to an exemplary embodiment of the present invention preferably includes receiving, at a target SUPL Enabled Terminal (SET), a SET list from an SUPL Location Platform (SLP); receiving an assistance data from a SET selected among SETs listed in the SET list; and location a position of the target set using the assistance data. A position locating method using Secure User Plane Location (SUPL) according to another exemplary embodiment of the present invention includes requesting, at a target SUPL Enabled Terminal (SET), at least one SET to send assistant data; receiving the assistant data from one of the least SET; and locating a position of the target SET based on the assistant data. | 05-06-2010 |
| 20110070842 | METHOD AND APPARATUS FOR BAND TRANSFER IN MULTIBAND COMMUNICATION SYSTEM - A method and apparatus for transferring to a second communication band and returning to an original communication band according to a channel state in a multiband communication system are provided. The method includes communicating with a peer device in a first band, determining a channel state of a second band, and transferring to the second band based on a result of the determination, thereby efficiently using a plurality of bands and thus improving a data transmission speed. | 03-24-2011 |
| 20110110440 | METHOD AND APPARATUS FOR CHANGING FREQUENCY BAND USED FOR COMMUNICATION BETWEEN DEVICES SUPPORTING MULTIPLE FREQUENCY BANDS - A method and apparatus for changing a frequency band used for communication between first and second devices supporting multiple frequency bands. The method includes transmitting a frequency band change request frame including information regarding a communication capability of the first device and a frequency band change request for requesting to change a frequency band currently being used for communication between the first and second devices, to the second device; receiving a frequency band change response frame corresponding to the frequency band change request frame, from the second device; and selectively changing the frequency band currently being used to another frequency band based on the received frequency band change response frame. | 05-12-2011 |
| 20110142122 | METHOD AND APPARATUS FOR TRANSMITTING VIDEO CONTENTS COMPRESSED BY CODEC - A method and apparatus for transmitting compressed video content are provided. The method includes transmitting a codec selection request frame, the codec selection request frame including an identifier of one or more codecs to be used to compress video content and requesting approval of the use of the codec, receiving a codec selection response frame, the codec selection response frame including result information indicating whether the use of the codec is approved, and transmitting video content frames for the video content compressed by the approved codec based on the codec selection response frame. Each video content frame includes frame type information indicating a type of compression applied to the video content included in the video content frame. | 06-16-2011 |
| 20110171914 | METHOD AND APPARATUS FOR CONTROLLING LINK MARGIN - A method and apparatus for controlling a link margin are provided. The method includes: receiving, from a second device, a link margin frame including information about the link margin related to a communication link between a first device and the second device; and performing at least one operation selected from among a change in transmission power, a change in a modulation and coding scheme (MCS), beam forming, and a change of the communication link to another frequency band, based on the received link margin frame. | 07-14-2011 |
| 20110206004 | METHOD AND APPARATUS FOR PERFORMING HAND-OVER - A method of performing hand-over in a personal basic service set (PBSS) including a plurality of stations and one coordinator is provided. An association request frame comprising PCP capability information, and requesting to associate to the PBSS, is received from each of the stations. The PCP capability information comprises information regarding at least one of whether each of the stations supports a power source capability of continuous power supply, whether each of the stations supports a channel time allocation function, and whether each of the stations supports a network clustering function. An association response frame, indicating whether the association request received from each of the stations is approved, is transmitted to each of the stations, and a priority to be a coordinator of the stations is determined based on the PCP capability information. Hand-over is performed with one of the stations according to the determined priority. | 08-25-2011 |
| 20110206128 | METHOD AND APPARATUS FOR TRANSMITTING VIDEO CONTENT COMPRESSED BY CODEC - A method and apparatus of transmitting video content compressed by a codec to a second device is provided. The method includes: transmitting a codec selection request frame to the second device, the codec selection request frame includes an identifier of at least one codec to be used to compress the video content and requests approval of the use of the at least one codec; receiving a codec selection response frame from the second device, the codec selection response frame includes approval information indicating whether the use of the at least one codec is approved; and transmitting video content compressed by the at least one codec to the second device based on the codec selection response frame. | 08-25-2011 |
| 20110207460 | METHOD AND APPARATUS FOR PERFORMING HANDOVER - A method of performing a handover between a first device and a second device is provided. The method including: transmitting a handover request frame for requesting a handover, including information about a reason for requesting the handover, to the second device; receiving a handover response frame including handover request result information indicating whether the handover request is accepted, from the second device; and selectively performing the handover with the second device based on the handover response frame. | 08-25-2011 |
