摘要： Methods and systems are employed by a wireless location system (WLS) for locating a wireless device operating in a geographic area served by a wireless communications system. An exemplary method includes monitoring a set of signaling links of the wireless communications system, and detecting at least one predefined signaling transaction occurring on at least one of the predefined signaling links. Then, in response to the detection of the at least one predefined network transaction, at least one predefined location service is triggered.

摘要： A wireless location system is configured to operate in a CDMA-based wireless communication network. In exemplary embodiments, location measuring units (LMUs) can synchronize to sectors of base stations and store sector timing information. In response to a request to geo-locate a mobile device communicating with a sector, sector timing information for the servicing sector is sent to other LMUs and the LMUs can use the sector timing information to detect uplink signals transmitted by the mobile device. The location of the mobile device can then be estimated based on time of arrival measurements made by the LMUs.

摘要： Systems and methods are provided for scanning files and directories in a distributed file system on a network of nodes. The nodes include metadata with attribute information corresponding to files and directories distributed on the nodes. In one embodiment, the files and directories are scanned by commanding the nodes to search their respective metadata for a selected attribute. At least two of the nodes are capable of searching their respective metadata in parallel. In one embodiment, the distributed file system commands the nodes to search for metadata data structures having location information corresponding to a failed device on the network. The metadata data structures identified in the search may then be used to reconstruct lost data that was stored on the failed device.

摘要： A method and apparatus for position determination is provided using measurements from both Global Positioning System (GPS) receivers and terrestrial-based Uplink Time Difference of Arrival (UTDOA) receivers. The method involves the transformation of downlink satellite measurements into equivalent UTDOA measurements by computing comparable cross-correlation coefficients and time differences of arrival with respect to a UTDOA reference station. The method includes a weighting operation whereby the relative weights of the UTDOA measurements and the relative weights of the GPS measurements are adjusted based on a theoretical scaling followed by empirical adjustments. The method further involves the efficient computation and combining of metrics that are used to minimize the weighted error between candidate location solutions and the UTDOA and GPS measurements.

摘要： In accordance with the automatic peripheral device sharing, a peripheral device that has been newly installed on a device is detected and is shared with one or more additional devices coupled to the device. A notification of the peripheral device is automatically published to the one or more additional devices. This notification includes an indication of how the one or more additional devices can access the peripheral device. Each of the one or more additional devices can receive this notification and determine whether the peripheral device can be automatically installed on that device without user input. For each of the one or more additional devices, the peripheral device is installed on that device only if the peripheral device can be automatically installed on that device without user input.

摘要： Modern cellular wireless communications providers strive to keep their network and subscribers secure through various means. The identity of the subscriber may be obfuscated through the use of a temporary identifier for most network transactions including signaling events, voice calls, SMS messages and data sessions. A subscriber's unique identity may only be transmitted over the air in an encrypted form. Similarly, the content of voice calls, SMS messages and data sessions may also be encrypted when transmitted over the air and even when transferred over internal network interfaces. However, the use of encryption presents significant challenges for law enforcement communities when court ordered lawful intercept is required to monitor and locate subscribers utilizing the wireless networks for illegal and/or terrorist purposes. A technique to aid in the determination of a subscriber's unique wireless identity and the decryption of encrypted signals would be very useful for lawful intercept. In this document we describe an architecture and technique to aid in the decryption of encrypted wireless signals for lawful intercept by determining the current encryption key. It may also be used to decrypt encrypted signals on internal interfaces of the wireless and wireline networks.
摘要翻译：现代蜂窝无线通信提供商努力通过各种方式保持网络和用户的安全。可以通过对大多数网络事务使用临时标识符来混淆订户的身份，包括信令事件，语音呼叫，SMS消息和数据会话。用户的唯一身份只能以加密形式通过空中传输。类似地，即使在通过内部网络接口传输时，语音呼叫，SMS消息和数据会话的内容也可以通过空中传输进行加密。然而，当法院命令合法拦截需要监视和定位利用无线网络进行非法和/或恐怖活动的用户时，加密使用对执法团体来说是一个重大的挑战。一种帮助确定用户唯一无线身份和加密信号解密的技术对于合法拦截将是非常有用的。在本文中，我们描述了一种通过确定当前加密密钥来帮助解密加密无线信号以进行合法拦截的架构和技术。它也可以用于解密无线和有线网络的内部接口上的加密信号。

摘要： In a network-based Wireless Location System (WLS), geographically distributed Location Measurement Units (LMUs) must be able to detect and use reverse channel (mobile to network) signals across multiple BTS coverage areas. By using Matched Replica correlation processing with the local and reference signals subdivided into discrete segments prior to correlation, the effects of mobile clock drift and Doppler shifts can be mitigated allowing for increased processing gain.
