摘要： The present invention discloses a method for a user terminal in a Wireless Local Area Network (WLAN) quickly accessing its home network. Pre-store in each user terminal, respectively, the identifications of all the WLANs with direct connections to the home network of the corresponding user terminal. For a user terminal that is in an area covered by more than one WLAN, compare the identification of each of the detected WLANs with the WLAN identifications stored in the current user terminal. A successful matching between the identification of a detected WLAN and a pre-stored WLAN identification then means that the home network of the current user terminal is connected with the corresponding WLAN access network and can be accessed via this WLAN. If a plurality of detected WLAN identifications match the stored identifications, select in accordance with a pre-defined selecting rule one of the corresponding WLANs and get accessed via the selected WLAN. This method enables a user terminal covered by more than one WLAN to find quickly a WLAN access network directly connected with its home network and to access the home network via this WLAN.

摘要： The present invention relates to an optimized interaction method of a WLAN user terminal selecting an access mobile communication network. In this method, after a wireless connection between the WLAN user terminal and a WLAN access network is established, the WLAN access network or the WLAN user terminal initiates an access authentication procedure, and the WLAN access network sends a user identity request message to the WLAN user terminal. After receiving the user identity request message, the WLAN user terminal determines network selection information to be currently carried according to a detecting result of whether the WLAN access network is changed or according to user selection information, and returning a message containing the determined network selection information to the WLAN access network. The WLAN access network then judges whether the network selection information in the received message indicates one of the mobile communication operation networks to which the WLAN access network is currently connected; if so, sends an access authentication request from the WLAN user terminal to a mobile communication operation network indicated in the network selection information, otherwise, the network sends a notification signaling to the WLAN user terminal, the WLAN user terminal completes subsequent operations according to contents in the notification signaling. With the present invention, when being accessed to a WLAN that is connected to multiple mobile communication operation networks, the WLAN user terminal is capable of selecting an optimal mobile communication operation network to access according to the requirements.

摘要： A zero-emissions power plant receives natural gas from wells at elevated pressure and temperature. Gas is expanded through one or more turbo-expanders, preferably reformed, and sent to a fuel cell where electricity, heat, carbon-dioxide, and water are generated. The carbon-dioxide is compressed by at least one compressor and piped downhole for sequestration. The turbo-expanders have shafts which preferably share the shafts of the compressors. Thus, energy given up by the natural gas in the turbo-expanders is used to run compressors which compress carbon dioxide for downhole sequestration. In one embodiment, the natural gas is applied to heat exchangers in order to generate a stream of liquid natural gas. The remainder of the gas is expanded through the turbo-expanders and processed in the reformer prior to being sent to the fuel cell. A shifter may be used between the reformer and fuel cell. A solid oxide fuel cell is preferred.
