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.

摘要： Disclosed herein is a method useful for target user equipment (UE) sending a location report. When the target UE is located in a first central network (CN) of a location service (LCS) system, the target UE reports the location report to the LCS system. If the target UE does not receive a location report response from the LCS system, when being located in a second CN of LCS system, target UE will continue to report the location report to LCS system. In accordance with one aspect of the disclosed method, the waste of location service system resource is avoided as well as the execution efficiency of location service is increased. In addition, during procedure of change of area event location request, the consequent processing of request thereof is guaranteed to be normal, so that execution efficiency of location service is increased. Moreover, message interaction between the function entities is saved for the exception cases. Accordingly, the waste of public land mobile communication network resource caused by generation of excessive useless messages is avoided.
摘要翻译： 本文公开了一种对目标用户设备（UE）发送位置报告有用的方法。 当目标UE位于位置服务（LCS）系统的第一中央网络（CN）时，目标UE向LCS系统报告位置报告。 如果目标UE没有从LCS系统接收到位置报告响应，则当目标UE位于LCS系统的第二CN时，目标UE将继续向LCS系统报告位置报告。 根据所公开的方法的一个方面，避免了位置服务系统资源的浪费，并且增加了定位服务的执行效率。 另外，在区域事件定位请求的更改过程中，对其请求的后续处理被保证是正常的，从而增加了定位服务的执行效率。 此外，针对异常情况保存了功能实体之间的消息交互。 因此，避免了由于产生过多无用的消息而导致的公共陆地移动通信网络资源的浪费。

摘要： The present invention provides a method for reducing the load on Home Subscriber Server (HSS)'s interface. After receiving a request message from Serving Call Session Control Function (S-CSCF) comprising the request for storing the name of the S-CSCF and for downloading the user's subscription information, HSS first stores the name of S-CSCF in the request message, then returns to the S-CSCF a response message comprising the user's subscription information. This invention simplifies the steps of inquiring about the user's subscription information, optimizes the service procedure, and reduces the load on HSS's interface. In addition, when receiving the inquiry message from I-CSCF, HSS returns directly to I-CSCF response message comprising the S-CSCF name and the S-CSCF capability information set that has the capability to meet the most strict service subscription requirement of the UE, further reducing the load on HSS's interface. This invention has no impact on the existing network architecture and services, nor is it needed to modify the existing interface specifications, thus being highly compatible and extendable.
摘要翻译： 本发明提供一种降低归属用户服务器（HSS）接口负载的方法。 在收到包含存储S-CSCF名称的请求的服务呼叫会话控制功能（S-CSCF）的请求消息和下载用户的订阅信息之后，HSS先将S-CSCF的名称存储在请求消息中， 然后向S-CSCF返回包含用户订阅信息的响应消息。 本发明简化了查询用户订阅信息，优化业务流程，降低了HSS接口负载的步骤。 另外，当从I-CSCF接收到查询消息时，HSS直接返回到包含S-CSCF名称和S-CSCF能力信息集的I-CSCF响应消息，该消息具有满足最严格的业务订阅要求的能力 UE进一步降低了HSS接口的负载。 本发明对现有的网络架构和服务没有影响，也不需要修改现有的接口规范，从而具有高度兼容性和可扩展性。

摘要： The present invention discloses a method for processing a location information request in a location service, comprising: a location information request initiator sending a location information request containing a processing indication to a location information request receiver; after receiving the location information request, the location information request receiver determining whether to perform synchronous processing or asynchronous processing for the location information request according to type of the processing indication, and then implementing corresponding processing for the location information request. This method is capable of effectively saving system resource of a LCS system, avoiding resource waste at a location service interface and increasing processing performance of a location service.
摘要翻译： 本发明公开了一种在位置服务中处理位置信息请求的方法，包括：位置信息请求发起者向位置信息请求接收者发送包含处理指示的位置信息请求; 在接收到位置信息请求之后，位置信息请求接收机根据处理指示的类型确定是否对位置信息请求进行同步处理或异步处理，然后对位置信息请求进行相应的处理。 该方法能够有效地节省LCS系统的系统资源，避免位置业务接口的资源浪费，提高定位业务的处理性能。
