20090156219 | HANDOVER METHOD IN MOBILE NETWORK, MOBILE TERMINAL AND MOBILE NETWORK SYSTEM THEREOF - A method of performing handover in a mobile communication network, a mobile communication terminal using the same, and a mobile network system are provided. The method of performing handover in a mobile communication network includes: receiving QoS requirement on a mobile service basis from a user terminal; determining a most suitable mobile network to QoS requirement of a mobile service as a network for handover; and requesting handover to a base station of a mobile network determined as a network for handover. Therefore, in consideration of characteristics of a mobile network and a quality of a service used by a user, by determining handover to an optimum mobile network on a service quality basis, service interruption due to performing unnecessary handover can be prevented and by effectively distributing traffic of a mobile network, overload of a system can be prevented. | 06-18-2009 |
20090156220 | METHOD AND APPARATUS FOR HANDOVER IN MOBILE NETWORK, AND MOBILE TERMINAL THEREOF - A method and an apparatus for performing handover in a mobile communication network and a mobile communication terminal using the same are provided. The method of performing handover in a mobile communication network includes: receiving information about signal intensity of mobile networks to which a user terminal can be connected; selecting at least one of connectable mobile networks as a network for handover using user information including information about user requirement and information about the received signal intensity; requesting approval of handover of the user terminal to the selected network for handover and receiving result information about the approval request from the network for handover; and transmitting information about a network in which handover is approved among the networks for handover to the user terminal. Therefore, in consideration of user information such as service characteristics, a user service environment, and user requirement, by selecting a network for handover, a mobile communication network service having a performance and a cost suitable for user request can be provided. | 06-18-2009 |
20090156221 | Handover method and apparatus in mobile network - A method and an apparatus for performing handover in a mobile communication network are provided. The method of performing handover in a mobile communication network includes: obtaining a service providing time period and a utility function on a candidate network basis; obtaining a selection function of each of the candidate networks using the utility function and the service providing time period; and selecting a network for handover among the plurality of mobile networks using the selection function. Therefore, in consideration of user satisfaction and a network service quality, utility functions are defined and by selecting a network for handover using the utility functions, a network suitable for a user environment can be effectively selected and thus it is possible to perform handover that has a performance and a cost suitable for user request and that can maximize a quality of a mobile service. | 06-18-2009 |
20120120794 | METHOD AND APPARATUS FOR CONTROLLING TRAFFIC - A method for controlling traffic in a mobile communication network is provided. A traffic control apparatus checks locations of a calling terminal and a receiving terminal, and determines whether to perform terminal-to-terminal direct communication based on the locations of the calling terminal and the receiving terminal. A base station of the calling terminal and a base station of the receiving terminal instruct the calling terminal and the receiving terminal to perform the terminal-to-terminal direct communication when the terminal-to-terminal direct communication is determined to be performed. | 05-17-2012 |
20120155306 | BASE STATION AND OPERATING METHOD THEREOF - A base station measures an amount of traffic within a downlink buffer. If the measured amount of traffic is larger than a threshold value, the base station adjusts a ratio of an available interval and an unavailable interval according to a ratio of the amount of traffic against the threshold value and length of a superframe. If the measured amount of traffic is smaller than the threshold value, the base station adjusts a ratio of the available interval and the unavailable interval according to a ratio of the threshold value against the amount of traffic and length of the superframe. | 06-21-2012 |

20110158532 | APPARATUS FOR DETECTING TEXT RECOGNITION REGION AND METHOD OF RECOGNIZING TEXT - A text recognition region detecting apparatus and a text recognition method are provided. A text recognition region is detected by expanding a region based on a user-specified position that is input through a simple manipulation by a user. A text recognition is performed on the detected text recognition region, thereby relieving a user from having to precisely input the text region and ensuring the user's convenience. | 06-30-2011 |
20110161637 | APPARATUS AND METHOD FOR PARALLEL PROCESSING - An apparatus and method for parallel processing in consideration of degree of parallelism are provided. One of a task parallelism and a data parallelism is dynamically selected while a job is processed. In response to a task parallelism being selected, a sequential version code is allocated to a core or processor for processing a job. In response to a data parallelism being selected, a parallel version code is allocated to a core a processor for processing a job. | 06-30-2011 |
20120151194 | BYTECODE BRANCH PROCESSOR AND METHOD - A bytecode interpreter in a computing system is provided. The interpreter assists in branch prediction by a host processor that processes a virtual machine such as JAVA® and DALVIK®, thereby reducing branch misprediction and achieving high performance. | 06-14-2012 |
20120185833 | CODE GENERATOR AND METHOD FOR GENERATING EXTRA CODE FOR A VIRTUAL MACHINE - In a virtual machine that uses a just-in-time complier (JITC) as a software execution environment, an idle time of a core to which the JITC is allocated is utilized to generate machine code in advance, thereby reducing a load on an interpreter. Accordingly, code execution performance of the interpreter is improved, and the utilization of a multi-core system that executes applications is increased. | 07-19-2012 |
20120185850 | CODE REARRANGER AND METHOD FOR REARRANGING CODE FOR A VIRTUAL MACHINE - Provided is an code rearranger and method for a virtual machine that uses a just-in-time-compiler (JITC) to manage a location of machine code stored in a code cache. The apparatus may rearrange consecutively-executable machine codes from among those stored in the code cache to be placed successively. | 07-19-2012 |
