20090279451 | TRANSMITTING/RECEIVING METHOD AND PROGRAM AND RECORDING MEDIUM - The present invention provides a transmitting/receiving method capable of selecting a combination of communication media of the own and its counterpart reflecting the preference of the user or an application for each of flows on communication terminals and capable of doing execution without being known by counterpart the preference information. It presents means for selecting a combination of CoAs (the CoA of the communication counterpart and that of the own) of the Mobile IP referring to the preference information of the application when communication terminals transmit/receive one or more flows (data flows) through one or more paths (communication channels). In consideration of combinations of flows and paths, the score is calculated for the combinations, and transmitted to the counterpart terminal of the communication, the approval is obtained to select the optimum path. As a result, the CoA suitable to the preferences of both parties can be selected for each flow. | 11-12-2009 |

20100208694 | MOBILE COMMUNICATION SYSTEM, RADIO COMMUNICATION METHOD, CORE NETWORK, USER EQUIPMENT, AND PROGRAM - A core network includes an external network reception section which receives data from an external network, a connection instruction processing section which transmits a paging request directed to user equipment upon receipt of the data and also transmits a connection instruction of a second radio communication type, a connection management section which registers a connection by the second radio communication type upon receipt of a connection request, and a transmission section which transmits the data. The user equipment includes a first radio communication type communication section which receives the paging request and receives the connection instruction, a second radio communication type connection section which uses the second radio communication type to transmit the connection request according to the received connection instruction and causes the communication state to transition to a reception enabled state, and a second radio communication type communication section which receives the data when the communication state of the second communication type is the reception enabled state. This makes it possible to provide the user equipment of an idle state with communication data using a radio communication type having no paging function. | 08-19-2010 |

20090310509 | COMMUNICATION SYSTEM AND COMMUNICATION TERMINAL - The present invention provides a communication system and a communication method for linking the switching of a transmission path with the switching of an application according to the change of a communication condition caused by the movement of a user in a mobile environment. A change of the communication condition caused by the movement of the user is always monitored and the transmission path is switched according to the state change of the transmission path. Here, the state of the transmission path between the terminal and the communication counter part terminal is obtained and compared to a priority reference for each of the applications, thereby selecting a transmission path appropriate for the application becomes possible and a service in corresponding to the communication condition can be provided by changing a content to that appropriate for the transmission path, simultaneously. | 12-17-2009 |
