    Abstract: Hybrid file delivery systems and methods divide one or more files into parts for transmission to plural user devices during a first transmission phase employing one or more one-to-many communication paths (e.g., broadcast or multicast), and then transmit missing file parts to designated user devices during a second transmission phase employing respective one-to-one communication paths. User devices are configured with specified criteria for when and how to report file delivery status to a file delivery center that maintains a database of target user devices, file delivery campaigns, and statuses of file delivery completion at the user devices. The file delivery center can employ the database information to determine cost benefit for delivery of a file using two different transmission modalities and control when to switchover to or commence the second transmission phase after the first transmission phase.

    Abstract translation: 在采用一个或多个一对多通信路径(例如,广播或多播)的第一传输阶段期间,混合文件传送系统和方法将一个或多个文件分成多个用户设备传输到多个用户设备,然后将丢失的文件部分传送到 在第二传输阶段使用相应的一对一通信路径的指定用户设备。 用户设备配置有指定的标准,用于何时以及如何将文件传送状态报告给维护用户设备的目标用户设备数据库,文件传送活动和文件传送完成状态的文件传送中心。 文件传送中心可以使用数据库信息来确定使用两种不同传输模式传递文件的成本效益,并且控制在第一传输阶段之后切换到或开始第二传输阶段的时间。

    Abstract: System, devices and methods are provided to automatically initiate an enhanced 911 (E911) call from a telematics control unit (TCU) (e.g., a TCU deployed with cellular modem or mobile phone in a vehicle) to an answering point (e.g. public safety answering point or access point (PSAP)). A wireless carrier (e.g., mobile service center (MSC)) employs a positioning determining entity (PDE) and algorithm to improve caller location determination using information provided by the TCU (e.g., GPS and dead reckoning information generated at the vehicle) and network location information when needed, and provides PDE estimated location of the caller to the PSAP (e.g., using a data channel and optionally a voice channel) to mitigate errors in TCU location data and reduce potentially conflicting location information provided to PSAPs from TCUs and wireless carriers or other phone service providers.
