摘要： A method for generating a pattern matching machine for identifying matches of a plurality of symbol patterns in a sequence of input symbols, the method comprising: providing a state machine of states and directed transitions between states corresponding to the plurality of patterns; applying an Aho-Corasick approach to identify mappings between states in the event of a failure, of the state machine in a state and for an input symbol, to transition to a subsequent state based on the directed transitions of the state machine, characterized in that one of the symbol patterns includes a wildcard symbol, and mappings for one or more states representing pattern symbols including the wildcard symbol are based on an input symbol to be received, by the pattern matching machine in use, to constitute the wildcard.

摘要： This invention relates to methods and systems for monitoring mobile service quality in a mobile network and also for determining parts of a mobile network which need expansion or upgrade. Embodiments of the invention monitor the market impact and/or service quality, and determine an expansion ranking. The market impact, service quality and/or expansion ranking may view the network from a plurality of perspectives, including a location perspective, an historical time perspective, a future time perspective and/or a network element type perspective. The results of the monitoring and determining can be acted on by predetermined rules and/or actions to derive a list of prioritized expansion tasks for the network.

摘要： This invention relates to methods and systems for localization. It is particularly concerned with localization techniques based on time difference of arrival for wireless devices. Embodiments of the invention relate to techniques in which a transmitter transmits periodic distinguishable signals which are relayed upon receipt by the client whose location is sought in a form distinguishable from that of the transmitter. Signals from both the transmitter and the client are received by at least three signal receivers which generate a time difference of arrival based on the difference taken for a signal to reach the receiver directly and via the client. Further embodiments of the invention provide a phase detector in the receivers to determine the time difference of arrival between the signals.

摘要： This invention relates to methods and devices for clock synchronization. The invention has particular application in the alignment of slave clocks to a master clock and in dealing with transmission delay asymmetries where the forward and reverse communication paths between the master and slave clocks have asymmetric transmission rates. Such methods and devices have particular application in small cell backhaul solutions for 4G/LTE deployments. In embodiments of the invention, the slave clock uses link rate information to estimate the transmission delay asymmetry and thus estimate the offset and skew of the slave clock. Embodiments provide a simple linear approximation technique and a Kalman filter-based technique for estimating offset and skew of the slave clock.

摘要： Techniques for enforcing a compliance requirement for a software application executing in a virtualized computing environment are disclosed. An identifier identifies a resource instantiated for the application's execution. A retriever retrieves a compliance characteristic for the application. The compliance characteristic is retrieved based on the identified resource and has an associated compliance criterion based on a formal parameter. The compliance criterion defines compliant resource states. A selector selects a software component for providing an actual parameter corresponding to the formal parameter . An evaluator evaluates the compliance criterion using the actual parameter. An application modifier, responsive to the resource lacking a compliant resource state, modifies the software application to have a resource with a compliant state. The identifier, selector, and evaluator respond to resource changes. The selector selects the software component based on an identification of one or more data items that the software component can provide.

摘要： The invention relates to a method and system that provide a continuous querying mechanism that analyses real-time data streams to generate relevant results. It leverages data grid and event processing technology to provide a high performance and extremely scalable continuous querying solution. An embodiment of the invention provides a flexible querying language and data storage to allow users to register their interest in specific types of data, e.g. processes. The users are notified of matching results using an event-based mechanism. In order to efficiently analyze a large amount of data, the embodiment uses a grid infrastructure that allows storage of the data across many grid nodes and distributes the query execution workload, avoiding the bottleneck represented by constantly querying a database. Continuous queries are stored in a Continuous Query Registry and that Registry is invoked every time an insert or update event occurs on the triple store.

摘要： Data messages having secure data location addresses other than a predefined set are handled by a user terminal (14) in the normal way by setting up a secure tunnel (181) to a server specified in the data message (16). As this would prevent any proxy server from performing any processing on the content of the data message, messages that require the proxy to perform process on the data messages are processed separately. Data messages (251) incorporating secure media access locators identifying a predefined set of known media servers are identified by a message processing function (41, 410, 44) and passed to a proxy server over a connection between the user terminal and the proxy which does not tunnel past the proxy server, such that the proxy server may generate a redirected media access locator for return to the user terminal (14).

摘要： One or more network based video servers is/are connected to one or more video receivers over a shared network. Pieces of video content are each encoded at a number of constant quality levels and stored on one or more of the network based servers. Responsive to requests from a receiver, video content is selected on a server and delivered over the shared network to the receiver. The system selects the quality level of the stream to deliver based on characteristics of the video stream currently being delivered, and the number of bits already buffered at the video receiver and the available network throughput. The aim is to select the video quality being delivered according to the available network throughput to maximize quality while ensuring that video data is delivered over the network in time to be decoded and displayed without interruption. Certain exemplary embodiments make that selection in advance.
摘要翻译：一个或多个基于网络的视频服务器通过共享网络连接到一个或多个视频接收器。每个视频内容的片段都以多个恒定的质量级别进行编码并存储在一个或多个基于网络的服务器上。响应于来自接收器的请求，在服务器上选择视频内容并通过共享网络传送到接收器。该系统基于当前正在传递的视频流的特性，以及已经在视频接收器处缓冲的位数以及可用的网络吞吐量来选择要传送的流的质量级别。目的是根据可用的网络吞吐量选择正在传送的视频质量，以最大限度地提高质量，同时确保视频数据在网络上及时传送，以便不间断地进行解码和显示。某些示例性实施例预先进行该选择。
