20130080509 | CLOUD COMPUTING ACCESS GATEWAY AND METHOD FOR PROVIDING A USER TERMINAL ACCESS TO A CLOUD PROVIDER - A cloud computing access gateway includes a cloud management module configured to store a cloud provider and information of a cloud computing service provided by the cloud provider. A user terminal interface module is configured to provide an interface with a user terminal, receive a service request indicating a cloud computing service from the user terminal, and send a result of the cloud computing service to the user terminal. A request analysis module is configured to analyze the received service request to identify the cloud computing service. A cloud selection module is configured to select a best cloud provider based on the cloud computing service. A cloud interface module is configured to provide an interface with the cloud provider, transmit the service request to the best cloud provider, and receive the result of the cloud computing service from the best cloud provider. | 03-28-2013 |
20120093088 | METHOD AND DEVICE FOR PROCESSING COMPONENT CARRIERS TO BE AGGREGATED FOR TRANSMISSION - A method for processing multiple Component Carriers (CCs) to be aggregated for transmission is provided in the present invention, the method comprising the steps of: acquiring a time domain signal of each of the multiple CCs; applying multiple fixed phase rotations respectively to the acquired time domain signal by utilizing phase rotation values in a set of phase rotations, so as to obtain multiple phase rotation versions of each CC; randomly selecting one of the multiple phase rotation versions of each CC to respectively constitute multiple candidate transmission groups, and acquiring an amplitude sum of the phase rotation versions for each of the multiple candidate transmission groups; determining a candidate transmission group having the minimum amplitude sum; and transmitting multiple phase rotation versions in the determined candidate transmission group having the minimum amplitude sum. The present invention substantively provides a general solution capable of minimizing CM/PAPR of aggregated CCs for UL and DL. | 04-19-2012 |
20120044854 | METHOD, BASE STATION, AND BROADCAST MULTICAST SERVICE CENTER FOR CREATING, UPDATING, AND RELEASING SYNCHRONIZATION ENTITIES - The present invention provides processes of creating, updating, and releasing SYNC entities between eNB and BM-SC, and an eNB and a BM-SC for implementing the processes of creating, updating, and releasing the SYNC entities. According to a solution of the present invention, a method of creating SYNC entities is provided, including: creating, at a BM-SC, a plurality of SYNC entities whose amount is equal to the total amount of services, and associating the created plurality of SYNC entities with the services in a one-to-one correspondence manner; sending a SYNC entity creating instruction to all eNBs within an MBSFN area; creating, at each eNB, a plurality of SYNC entities whose amount is equal to the total amount of services based on the received SYNC entity creating instruction, and associating the created plurality of SYNC entities with the services in a one-to-one correspondence manner. | 02-23-2012 |
20110002311 | GATEWAY, BASE STATION AND METHOD FOR WINDOW-BASED CONTENT SYNCHRONIZATION - The present disclosure relates to a gateway, base station and method for window-based content synchronization technology. The gateway according the present invention comprises; a receiving unit for receiving a data packet; a window counting unit for counting the data packet, such that a predetermined number of packets forms a window, the number being a window size; a sequence number counting unit for generating a sequence number of the packet; a timestamp setting unit for setting a timestamp for the packet; and a processing unit for including the generated sequence number, the timestamp and a byte count in the packet to be transmitted. The base station according to the present invention comprises: a receiving unit for receiving a data packet; an information extracting unit for extracting a sequence number, a timestamp and byte count information from the data packet; a window counting unit for counting the received packets based on the extracted sequence number so as to form a window; and a processing unit for setting an anticipated air interface transmission time for the packets in the current window based on the extracted timestamp. The gateway or base station according to the present invention operates well with statistical multiplexing and has an improved overall performance in terms of synchronization processing delay and control packets load. | 01-06-2011 |
