    • A system and method to reduce the time to transfer files from one computer to another over a communications network, such as the Internet, by avoiding the synchronous timing limitations of current transfer methods. A file that is intended to be transferred from a transmitting computer to a receiving computer is partitioned into multiple synchronous block portions of the existing file, prior to transfer. Each block subportion of original file is compressed and queued for transmission to a target receiving computer. The compressed blocks are kept in a cue, encrypted, and transmitted asynchronously to a target receiving computer over a selected communications network. Upon receipt at the receiving computer of any of the transmitted blocks, blocks are decrypted, decompressed, and asynchronously reconstructed into the original file. Since the transmission of blocks to the receiving computer occurs asynchronously, as well as the transmission preparation steps, overall transmission times are improved.
    • 通过避免当前传输方法的同步定时限制,减少通过通信网络(例如因特网)将文件从一台计算机传送到另一台计算机的时间的系统和方法。 在传送之前,将要从传送计算机传送到接收计算机的文件被划分成现有文件的多个同步块部分。 原始文件的每个块子部分被压缩并排队等待传输到目标接收计算机。 压缩的块被保持在提示中,被加密,并且通过所选择的通信网络异步地发送到目标接收计算机。 在接收计算机上接收任何发送的块时,将块解密,解压缩并且异步地重构成原始文件。 由于向接收计算机发送块异步发送以及传输准备步骤,所以整体传输时间得到改善。

    • A communication system includes a switching network and a wireless network. The switching network includes a first gateway for receiving a communication from a caller, a second gateway for establishing an external connection through which the communication can be routed, and a command center that allows the first and second gateways to make an internal connection. The wireless network includes a visited mobile switch center and a home location register. The visited mobile switch center generates routing information, receives the communication from the external connection of the switching network, and routes the communication to a wireless network subscriber. The home location register locates the visited mobile switch center, and passes the routing information from the visited mobile switch center to the command center of the switching network. The command center causes the external connection to be established based on the routing information.
    • 通信系统包括交换网络和无线网络。 交换网络包括用于接收来自呼叫者的通信的第一网关,用于建立可以路由通信的外部连接的第二网关,以及允许第一和第二网关进行内部连接的命令中心。 无线网络包括被访问的移动交换中心和归属位置寄存器。 被访问的移动交换中心生成路由信息,从交换网络的外部连接接收通信,并将通信路由到无线网络用户。 归属位置寄存器定位被访问的移动交换中心,并将路由信息从被访问的移动交换中心传递到交换网的命令中心。 命令中心根据路由信息建立外部连接。
