20090011301 | Controlling the Requested Power Output of a Fuel Cell System - A fuel cell system of a type that uses an accessory to supply fuel gas and oxidant gas to a fuel cell to generate electric power is disclosed. The fuel cell system includes a load parameter detector that detects a load parameter of the accessory. An actual accessory power computing device computes the electric power actually consumed by the accessory based on the detected load parameter. A steady accessory power computing device computes a steady accessory electric power consumption by the accessory that would be needed for supplying the fuel cell with gas to generate an amount of required electric power from the fuel cell system based on the steady electric power consumption characteristics of the accessory. An accessory power correcting device computes an electric power correction quantity such that the correction quantity may be combined with the steady accessory power to approach the actual accessory electric power consumption and the accessory power correcting device corrects the steady accessory electric power consumption based on the electric power correction quantity. A power generation controller controls the power generation of the fuel cell system based upon the required electric power to be generated by the fuel cell system and upon the computed steady accessory electric power consumption corrected by the accessory power correcting device. | 01-08-2009 |
20110188455 | MOBILE COMMUNICATION METHOD, MOBILE STATION AND MOBILE SWITCHING CENTER - A mobile communication method according to the present invention includes the steps of: transmitting, to a mobile switching center MME/SGSN, a NAS connection establishment request for the specific communication, while an AS connection is established between the mobile station UE and a radio access network apparatus eNB/RNC; determining, at the mobile switching center MME/SGSN, to restrict establishment of the NAS connection for the specific communication, when the NAS connection establishment request signal is received and when a predetermined condition is satisfied; and restricting, at the mobile station UE, transmission of a first connection establishment request signal and transmission of the NAS connection establishment request signal, after reception of a rejection signal including a restriction time period for restricting establishment of the NAS connection for the specific communication until expiry of the restriction time period. | 08-04-2011 |

20110205970 | MOBILE COMMUNICATION METHOD, MOBILE STATION AND MOBILE SWITCHING CENTER - A mobile communication method according to the present invention includes the steps of: transmitting, to a mobile switching center MME/SGSN, a NAS connection establishment request for the specific communication, while an AS connection, is established between the mobile station UE and a radio access network apparatus eNB/RNC; determining, at the mobile switching center MME/SGSN, to restrict establishment of the NAS connection for the specific communication, when the NAS connection establishment request signal is received and when a predetermined condition is satisfied; and restricting, at the mobile station UE, transmission of a first connection establishment request signal and transmission of the NAS connection establishment request signal, after reception of a rejection signal including a restriction time period for restricting establishment of the NAS connection for the specific communication until expiry of the restriction time period. | 08-25-2011 |
20110206005 | MOBILE COMMUNICATION METHOD, MOBILE SWITCHING CENTER, AND MOBILE STATION - Disclosed is a mobile communication method having: a step wherein, when the bearer status changes for a cell under the control of a WCDMA mobile communication system while the location of a mobile station (UE) is registered with a WCDMA mobile switching center (SGSN) and an LTE mobile switching center (MME), a synchronization process is performed on the bearer status of the mobile station (UE) between the WCDMA mobile switching center (SGSN) and the LTE mobile switching center (MME); and a step wherein the WCDMA mobile switching center (SGSN) notifies the mobile station (UE) that the synchronization process has occurred. If the bearer status has changed and the mobile station (UE) has received the aforementioned notification, the location of the mobile station (UE) is not registered with the LTE mobile switching center (MME) when moved from a cell under the control of the WCDMA mobile communication system to a cell under the control of the LTE mobile communication system. | 08-25-2011 |
20110269495 | MOBILE COMMUNICATION METHOD, RADIO ACCESS APPARATUS, AND GATEWAY APPARATUS - A mobile communication method according to the present invention includes the steps of: when a gateway apparatus (S-GW) is switched from a first state where downlink data is transmitted to a first radio access apparatus to a second state where the downlink data is transmitted to a second radio access apparatus, transferring, from the first radio access apparatus to the second radio access apparatus, the downlink data which is received from the gateway apparatus and to which specific information is added; and transmitting, from the second radio access apparatus to a mobile station (UE), transfer downlink data which is transferred from the first radio access apparatus and to which the specific information is added, before new downlink data transmitted from the gateway apparatus (S-GW). | 11-03-2011 |
