摘要： A method is provided in one example embodiment and includes providing an Internet Protocol (IP) address based on an authentication request associated with a device, the authentication request being associated with a Wi-Fi protocol. The method also includes identifying a Wi-Fi event associated with the IP address, and mapping the Wi-Fi event to a WiMax event. Further, the method includes providing a WiMax message, which is based on the Wi-Fi event, to a network element. In other embodiments, the mapping further includes converting the Wi-Fi event to the WiMax message such that the WiMax message is presented to the network element in a WiMax format. The same IP address can be used for both the Wi-Fi event and the WiMax message. In yet other embodiments, the method includes communicating a disconnection request to the network element when the device moves from a Wi-Fi coverage area to a WiMax coverage area, mapping a new WiMax event to a new Wi-Fi event, and providing a Wi-Fi message, which is based on the new WiMax event, to the device.

摘要： One or more techniques and/or systems are disclosed for predicting when a signal handoff may occur from a current base station to a neighboring base station for a mobile device. An indication of signal strength between the mobile device and the current base station and an indication of signal strength between the mobile device and a (e.g., closest) neighboring base station can be monitored by the mobile device. A difference between these signal strength indications can be determined and compared against a threshold (e.g., based upon historical signal handoffs) to predict when and/or where a signal handoff may occur. The predicted signal handoff may be determined by the mobile device and a corresponding notification can be provided so that appropriate action may be taken (e.g., a user may not initiate a call and/or an application may not attempt to communicate data).
摘要翻译：公开了一种或多种技术和/或系统，用于预测何时可以从当前基站到移动设备的相邻基站发生信号切换。移动设备和当前基站之间的信号强度的指示和移动设备与（例如最近的）相邻基站之间的信号强度的指示可以被移动设备监视。可以确定这些信号强度指示之间的差异并将其与阈值进行比较（例如，基于历史信号越区切换）来预测信号切换可能发生的时间和/或位置。可以由移动设备确定预测的信号切换，并且可以提供相应的通知，使得可以采取适当的动作（例如，用户可能不发起呼叫和/或应用可能不尝试传送数据）。

摘要： The simultaneous localization and RF modeling technique pertains to a method of providing simultaneous localization and radio frequency (RF) modeling. In one embodiment, the technique operates in a space with wireless local area network coverage (or other RF transmitters). Users carrying Wi-Fi-enabled devices traverse this space while the mobile devices record the Received Signal Strength (RSS) measurements corresponding to access points (APs) in view at various unknown locations and report these RSS measurements, as well as nay other available location fix to a localization server. A RF modeling algorithm runs on the server and is used to estimate the location of the APs using the recorded RSSI measurements and any other available location information. All of the observations are constrained by the physics of wireless propagation. The technique models these constraints and uses a genetic algorithm to solve them, thereby providing an absolute location of the mobile device.
摘要翻译：同时定位和RF建模技术涉及提供同时定位和射频（RF）建模的方法。在一个实施例中，该技术在具有无线局域网覆盖（或其他RF发射机）的空间中操作。携带启用Wi-Fi的设备的用户遍历此空间，而移动设备在各种未知位置记录与接入点（AP）相对应的接收信号强度（RSS）测量值，并报告这些RSS测量值以及其他可用位置修复本地化服务器。 RF建模算法在服务器上运行，并用于使用记录的RSSI测量和任何其他可用位置信息来估计AP的位置。所有的观察都受到无线传播的物理学的限制。该技术对这些约束进行建模，并使用遗传算法来解决这些约束，从而提供移动设备的绝对位置。
