20100074351 | METHOD AND APPARATUS FOR PROCESSING DATA FOR TRANSMISSION IN A MULTI-CHANNEL COMMUNICATION SYSTEM USING SELECTIVE CHANNEL INVERSION - Techniques to process data for transmission over a set of transmission channels selected from among all available transmission channels. In an aspect, the data processing includes coding data based on a common coding and modulation scheme to provide modulation symbols and pre-weighting the modulation symbols for each selected channel based on the channel's characteristics. The pre-weighting may be achieved by “inverting” the selected channels so that the received SNRs are approximately similar for all selected channels. With selective channel inversion, only channels having SNRs at or above a particular threshold are selected, “bad” channels are not used, and the total available transmit power is distributed across only “good” channels. Improved performance is achieved due to the combined benefits of using only the NS best channels and matching the received SNR of each selected channel to the SNR required by the selected coding and modulation scheme. | 03-25-2010 |

20090150248 | SYSTEM FOR ENHANCING PAYMENT SECURITY, METHOD THEREOF AND PAYMENT CENTER - A system for enhancing payment security includes a payment network interface unit for communicating with a POS terminal through a payment network; a database for storing a card number and password of a payment tool of a user and a number of a mobile terminal of the user associated with the card number; an acquiring means for searching in the database to obtain the number of the user's mobile terminal associated with the card number; a receiving/sending unit for sending, according to the obtained number of the user's mobile terminal, a request for a transaction password of the payment tool to the user's mobile terminal by means of a wireless network; and an authentication means for authenticating whether or not the transaction password of the user's payment tool returned from the user's mobile terminal matches with the password stored in the database. | 06-11-2009 |
20090270073 | AUTHENTICATING IDENTITY OF CALLER - A method, apparatus, system, and computer readable medium for authenticating the identity of a caller. An authentication device authenticates a caller's identity based on received information of the caller and an identifier generation device generates an identifier containing the caller's identity. The authentication information is supplied to a mobile telephone user acting as a callee. Therefore, the callee knows the caller's identity, thereby providing a secure delivering channel. | 10-29-2009 |
20090300414 | METHOD AND COMPUTER SYSTEM FOR MAKING A COMPUTER HAVE HIGH AVAILABILITY - A method and a computer system for making a computer achieve high availability. The method includes running a host virtual machine on a host virtual machine container; running a servant virtual machine on the servant virtual machine container; and synchronizing the host virtual machine and the servant virtual machine by using an I/O instruction. The system includes at least two computers including a host computer and a servant computer, each computer including a virtual machine container; a virtual machine running on the virtual machine container; and a communication channel making the virtual machine container execute a virtual machine synchronization operation. The virtual machine synchronization operation of the virtual machine container is triggered by the virtual machine executing I/O instructions. | 12-03-2009 |
20100306339 | P2P CONTENT CACHING SYSTEM AND METHOD - A P2P content caching system, method, and computer program product for a P2P application on a computer network device. The system includes: a content analyzer; and a content manager. The method includes: determining P2P hotspot downloading contents of the P2P application on the computer network device; downloading the determined P2P hotspot downloading contents into a local memory, and requesting a directory server of the P2P application to register a P2P content caching system as a P2P content provider of the downloaded P2P hotspot downloading contents; and providing the downloaded P2P hotspot downloading contents to a P2P participant in response to a request from the P2P participant to the downloaded P2P hotspot downloading contents. | 12-02-2010 |
20140172922 | METHOD FOR GENERATING SIMPLE OBJECT ACCESS PROTOCOL MESSAGES AND PROCESS ENGINE - A method for generating a Simple Object Access Protocol (SOAP) message in XML during execution of a process in a SOA-based process engine apparatus and a corresponding process engine apparatus. The method includes: generating and storing an XML character string containing a fixed SOAP message skeleton; generating and storing an XML character string containing an instance-constant variable; generating an XML character string containing a dynamic variable; and concatenating the XML character string containing the fixed SOAP message skeleton and the XML character string containing the instance-constant variable as previously stored and the XML character string containing the dynamic variable by a character string concatenating operation to generate a SOAP message. A process engine apparatus including a message analyzer unit, a message pre-composer unit, a character string depository, and a message composer unit is also provided. | 06-19-2014 |
