Typically, the calling terminal is connected to a calling-side communication network, and the called terminal is connected to a called-side communication network; the called-side communication network includes an access request receiving device that receives an access request sent from the calling terminal; an access request cancel determination device that determines whether or not the received access request is cancelled; and an access request cancel notice sending device that sends an access request cancel notice when the access request is cancelled; and the calling-side communication network includes an addressee information communicating device that communicates addressee information to the calling terminal based on the access request cancel notice, where the addressee information is information of an addressee to be accessed so as to withdraw the cancellation of the access request. | 04-03-2014 |
20140126541 | COMMUNICATION SYSTEM AND COMMUNICATION CONTROLLING METHOD - A communication method in LIPA/SIPTO architecture is provided which, when a user equipment (UE) is to connect from a serving area to an external network, allows re-selection of an optimal gateway. The communication method allows selecting a gateway apparatus physically or topologically close to a site, where the user equipment is attached. | 05-08-2014 |
20140146791 | MOBILE COMMUNICATION SYSTEM, MOBILE STATION, SWITCHING STATION, AND LOCATION REGISTRATION METHOD FOR MOBILE STATION - A decrease is realized in network load caused by a change in selection of location registration device or an increase or decrease in the number of installations, on a circuit switching network side. A mobile communication system includes a mobile station, a packet switching station, and a plurality of location registration devices that perform location management of the mobile station. With respect to the mobile station, after one location registration device is already selected from among the plurality of location registration devices, when the mobile station performs location registration, an NRI (Network Resource Identifier) included in a TMSI (Temporary Mobile Station Identifier) is transmitted to the packet switching station. The packet switching station makes a request for location registration with respect to the one location registration device, based on the NRI. | 05-29-2014 |

20140185447 | COMMUNICATION SYSTEM AND COMMUNICATION CONTROL METHOD - A node on a core network, in accordance with a connection state of a terminal, releases a transmission path resource which is made unnecessary due to LIPA (Local IP access) or SIPTO (Selected IP traffic offload) connection configuration. | 07-03-2014 |
20140211728 | COMMUNICATION SYSTEM, METHOD, AND APPARATUS - A core network includes a plurality of nodes that serve as nodes managing mobility of a terminal and that are different with regards to service functions that nodes provide to the terminal. Based on subscriber information and terminal information, a node to be connected to the terminal is selected on the core network side, depending on a service characteristic utilized by the terminal or on a type of the terminal and the terminal is connected to the selected node. | 07-31-2014 |
20140269588 | RADIO COMMUNICATION DEVICE FOR MOBILE COMMUNICATION SYSTEM - A mobile communication network includes a radio communication device which is installed in a mobile communication network to carry out radio communication with a mobile terminal, a gateway which relays a communication from the terminal device from the radio communication device to the Internet, and a node which carries out an authentication process in response to a connection request from the mobile terminal. The gateway is installed in the radio communication device or in a carrier network. The node establishes a direct tunnel between the radio communication device and the gateway, so that the mobile that the mobile terminal is connected to the Internet via the direct tunnel and via the mobile communication network. Thus, it is possible to reduce traffic simply passing through the carrier network. | 09-18-2014 |

20150063306 | MOBILE COMMUNICATION SYSTEM - A mobile communication system and method that includes a radio access system employing a first communication scheme supporting packet-switched communication and a radio access system employing a second communication scheme supporting both circuit-switched communication and the packet-switched communication. The mobile communication system is configured to switch between a first communication state and a second communication state realizing single radio voice call continuity (SRVCC). The first communication state is when a first mobile station visits the radio access system employing the first communication scheme, and performs voice communication with a second mobile station and packet communication by using packet-switched system. The second communication state is when the first mobile station visits the radio access system employing the second communication scheme, and performs voice communication with the second mobile station by using circuit-switched system, and performs packet communication with the second station by using the packet-switched system. | 03-05-2015 |
