  • Patent number: 9326180
    Abstract: Even if a failure has occurred in core network equipment in a state in which bearers are established between a large number of UEs and a packet data network, congestion in the network is avoided. A mobile communication method according to the present invention includes steps of transmitting, by an MME, to transmit a “PDN Disconnection Request/Detach Request” including barring time to a UE when the MME disconnects a bearer between the UE and the packet data network due to a predetermined reason such as a failure in a S-GW/P-GW or the MME in a state in which the bearer is established, and barring, by the UE, a mobile originating call directed to the packet data network for the barring time.

  • Patent number: 8973353
    Abstract: An exhaust gas post-treatment unit includes a diesel particulate filtering device that treats engine exhaust gas, a selective catalyst reduction device that treats the engine exhaust gas, a connecting pipe, an injection device, a cooling water supply pipe and a cooling water return pipe. The connecting pipe connects the diesel particulate filtering device and the selective catalyst reduction device. The injection device is disposed on the connecting pipe and injects a reducing agent into the exhaust gas supplied to the selective catalyst reduction device. The a cooling water supply pipe guides cooling water to the injection device to cool the injection device. The cooling water return pipe discharges the cooling water from the injection device. At least one of the cooling water supply pipe and the cooling water return pipe has a convection section extending upward along the connecting pipe from a connecting portion with the injection device.

  • Publication number: 20120314586
    Abstract: In a SGSN, upon receiving data addressed to a mobile station by a receiving unit when disconnection of a radio connection with the mobile station is detected by a disconnection detection unit, a relay/non-relay determination unit determines whether or not to relay the data based on the type of communication determined by a communication type determination unit and performs relay of the data according to the determination. This allows the relay of data to be stopped for the type of communication such as conversational communication in SIP, thus preventing the transmission of unnecessary data to the mobile station and thereby reducing the consumption of a resource for radio communication.
