20090262685 | METHOD AND APPARATUS FOR MOBILE IP ROUTE OPTIMIZATION - The current application concerns a method, mobile node, home agent and system for route optimisation between a mobile node and at least one correspondent node in a packet switched network, wherein a route via a first home agent is redirected via a second home agent. The mobile node sends an extended home test initiation message comprising following information: authentication data, an address of the correspondent node, a first home address and a second home address. The first home agent receives the extended home test initiation message and sends an extended home test message to the second home agent, the extended home test message comprising the information from the extended home test initiation message. The second home agent receives the extended home test message and a communication is routed between the mobile node and the at least one correspondent node via the second home agent. | 10-22-2009 |

20140003348 | DETACHMENT OF A MOBILE TERMINAL FROM A MOBILE COMMUNICATION SYSTEM | 01-02-2014 |
20140016614 | SHORT MESSAGE TRANSMISSION AND HANDOVER PROCEDURES - The present invention relates to an improved method for handover of a mobile node from E-UTRAN to UTRAN in a scenario where SMS is the only service of the mobile node. The improved handover method allows saving radio resources by establishing the signalling connection for SMS exchange in the target network, and avoiding the data connection in the target network, since it is not used. The MME takes the decision to establish or not the data connection in the target UTRAN, and accordingly instructs the SGSN and UE to set the corresponding PDP contexts for the data connection to a “preserved” state, so as to avoid the establishment of same. Embodiments further relate to improved SMS delivery for IDLE mode UEs that activate ISR so as to avoid the involvement of the MSC server. Instead, packet-switched domain nodes are to be involved only. | 01-16-2014 |
20140177583 | SERVER AND COMMUNICATION TERMINAL - Disclosed is a technique for reporting the IP address of a UE using a response message to a device trigger. A control message receiving unit receives, from a network, a control message generated based on a trigger request message transmitted from the predetermined communication device for requesting the transmission of the control message to a communication terminal. A determining unit determines whether to perform communication with the predetermined communication device using an IP packet. A connection management unit acquires an IP address allocated to an IP connection used in communication with the predetermined communication device when determining to perform the communication using the IP packet at the time of receiving the control message at the control message receiving unit. A response message transmitting unit transmits a response message to the control message to the network, where the response message includes the IP address acquired by the connection management unit. | 06-26-2014 |

20080241621 | Energy storage system - A closed loop energy storage system configured with a hydrogen tank, an oxygen tank, a fuel cell stack and an electrolyzer. A heat exchanger freeze-dries the hydrogen and oxygen prior to their storage in their respective tanks. The heat exchanger also uses excess fuel cell heat to preheat streams of hydrogen and oxygen coming from the tanks. Phase separators serve both to separate water from hydrogen and oxygen, and to store the water. A thermal management system encloses all the system components except the tanks. An airfoil-shaped shell covers the system, and the larger of the two tanks extends substantially across the shell at its point of greatest camber thickness. The tanks are composed of polymer liners integral with composite shells. | 10-02-2008 |
