  • Patent number: 6834102
    Abstract: To provide a transfer control system that allows a call to be retransferred by a command from a source communication terminal and is capable of improving the convenience of a user issuing the command. In-communication information describing that a second terminal and a third terminal are now in communication with each other after a call is transferred in a state where a first terminal and the second terminal are in communication with each other is stored in a call state storage device. When a retransfer command is issued by the first terminal, the call is transferred to a fourth terminal by referring to the in-communication information stored in the call state storage device, thereby establishing communication between the second terminal and the fourth terminal.

  • Patent number: 6512924
    Abstract: To register current codec types of a mobile station with a network side, the mobile station 11 notifies, when it conducts the location registration or a mobile user replaces his or her old mobile station, a visitor location switching system 5, which is associated with the current location of the mobile station, of the codec types supported by the mobile station 11 using a mobile communication control signal between the mobile station and the mobile network. Receiving the notification, the visitor location switching system 5 enters the update of the codec types into a location register 41 in a memory home station that controls the mobile network 2. The codec types can be thus registered into the mobile network 2 using the mobile communication control signal. Since the mobile network 2 can always acquire the latest codec types for the mobile station, the discrepancy is canceled between the codecs the mobile station supports and the codecs the network registers.

  • Publication number: 20020147023
    Abstract: In an information providing system, a user inputs desired mobile ID number to a client terminal. The client terminal transmits a request for location information on the mobile station including the mobile ID number to a location server via a location information server. The location server transmits a request for object movement information corresponding to the mobile station to an object information server. The location information server obtains the information from a traffic control device. Location information on the mobile station obtained by the location information server is transmitted to the terminal.

  • Patent number: 4863356
    Abstract: A multi-cylinder piston-operated compressor having a combined cylinder block closed on both axial ends by front and rear housing and provided therein with a reciprocative piston mechanism, for sucking, compressing, and discharging a refrigerant gas, and a connecting flange, from which the refrigerant gas after compression is sent toward a cooling circuit. The connecting flange defines a muffling chamber in cooperation with a circumferential section of the combined cylinder block for suppressing the pulsation in discharge pressure of the refrigerant gas. The compressor further has a gas expansion chamber in which an expansion and a partial collision of the compressed refrigerant gas spouted from orifices take plate to weaken the pulsation in the discharge pressure of the gas with the least discharge loss.
