20080198782 | Information Communication Device, Information Communication Method, and Program - A purpose of the present invention is given as follows: That is, QoS of isochronous data can be effectively secured, and asynchronous data can be transferred with a small delay. | 08-21-2008 |
20080198783 | METHOD AND SYSTEM FOR IMPROVING BANDWIDTH UTILIZATION OVER A FIXED NETWORK - Bandwidth utilization over bearers in a fixed cellular network is improved by reducing the amount of data required to be transported. At each side of the bearer, data blocks (such as Iub blocks) are received and, prior to transmitting them across the bearer, they are analyzed to determine if they can be modified in such a manner to decrease the amount of data. On the other end of the bearer, received blocks are analyzed to determine if they have been modified, and if so, the blocks are reconstructed to a format that may not be identical to the original format but, that is operationally equivalent from a user perspective. The modifications to the blocks can be based on the type of data being transmitted. For instance, if the data is for a video session or and audio session, the modifications can be different. Information regarding the reconstruction of the blocks can be sent to the other end of the bearer as a part of the data or through other channels. | 08-21-2008 |

20090016248 | CODING METHODS OF COMMUNICATING IDENTIFIERS IN PEER DISCOVERY IN A PEER-TO-PEER NETWORK - Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information). | 01-15-2009 |

20090274080 | Method for Unifying Operations of Boards by Using Logical Addresses Thereof - The present invention relates to a method or unifying operations of a plurality of boards in a CDMA communication system by using logical addresses of the boards. Conventionally, since a board with a physical slot ID must be attached to a slot of the system corresponding to the physical slot ID, the board cannot be recognized by the system if it is attached to another slot of the system. In the present invention, a board is attached to a slot of the system on the basis of a logical address of the board, which is stored in a board configuration information. According to the present invention, since a board can be attached to any slot of the system regardless of the physical slot ID of the board, the boards can be easily managed. | 11-05-2009 |

20100061283 | MOBILE RADIO SYSTEM CAPABLE OF CONTROLLING BASE RADIO STATION WITHOUT IMPOSSIBILITY - A mobile radio system comprises first through N-th radio base stations, where N represents a positive integer which is greater than one. On a start-up sequence of an n-th radio base station, a base station control apparatus transmits an n-th individual identifier as a station identifier, to the n-th radio base station to allocate the n-th individual identifier to the n-th radio base station, where n is a variable between one and N, both inclusive. The base station control apparatus transmits a transmission message signal having the n-th individual identifier as a transmission individual identifier to the n-th radio base station to carry out a link connection between the base station control apparatus and the n-th radio base station. In the n-th radio base station, an ATM reception section compares the transmission individual identifier with the n-th station identifier to abandon the transmission message signal when the transmission individual identifier is not coincident with the n-th station identifier. A CPU makes the ATM reception section become a reset state when the ATM reception section continues to abandon the message signal during a predetermined time duration. | 03-11-2010 |
