20080208607 | Method and Apparatus For Providing Customized Contents Based on Terminal Information - Provided is a method and apparatus for providing customized contents based on terminal information. The method includes obtaining information on a terminal that operates contents; if a user selects contents, determining whether the selected contents are available or if it is necessary to request a contents provider to provide the contents, if necessary, requesting the contents provider to provide the contents via a predetermined communication network and receiving the contents from the contents provider; determining whether a file format of the available contents or the received contents is converted in order to perform the contents in the terminal, and if necessary, converting the file format of the contents, and preparing for the contents; and transmitting the prepared contents to the terminal and providing the transmitted contents to the user. The user can easily obtain contents even when the user does not recognize necessary system information of a user's device, reduce time taken to convert the contents and prepare for a preliminary process, and propose a reasonable method of using intangible property rights, which leads a contents manufacturer and user into a lawful environment to work within legal boundaries. Furthermore, an existing mobile communication network is not required to download the contents, which helps to avoid overcharges. It is not necessary to prepare for contents every time the user moves. | 08-28-2008 |
20080279152 | METHOD AND APPARATUS FOR PERFORMING POWER CONSUMPTION BASED HANDOVER BETWEEN HYBRID NETWORKS - Provided are a method and apparatus for performing power consumption based handover between hybrid networks. The method includes listing candidate networks based on a traffic class and terminal power consumption expected for each of the hybrid networks, and selecting a network for the handover according to the traffic class and a user preference from among the listed candidate networks. Accordingly, power can be saved, and simultaneously a network can be effectively selected. | 11-13-2008 |
