    • A wireless telecommunications system includes facilities in a wireless hand-held device (WHHD) that allows a user to browse files available to that user on storage devices in an enterprise network, and to identify one or more such files to be attached to an e-mail message to be composed on or transmitted from the handheld. The system includes facilities in an enterprise network, such as a file delivery server, that cooperates with the WHHD to provide the file browsing service. A mail agent cooperates with the WHHD, responsive to instruction from the handheld to send an e-mail message that is to contain an attachment, to request the file delivery server to retrieve the identified files and assemble an e-mail containing those files as attachments. The WHHD may receive from the user appropriate credentials needed to access files available to that user on storage devices in the enterprise network, and may forward the credential to the file delivery server and the mail agent. These components may use the credentials to provide the file browsing service and to retrieve the identified files.

    • A Global Positioning System (GPS) commercial receiver including a digital processor disposed to utilize the energy of both the L1 and L2 GPS satellite signals in order to derive an estimate of an unknown security code used to modulate the signals. In processing the signal energy from the received L1 and L2 signals in accordance with statistical Maximum A Posteriori (MAP) estimation theory, the received L1 signal is correlated with a locally generated replica of the P-code, and passed through a bandpass filter having a bandwidth approximating the bandwidth of the unknown modulation code. The received L2 signal is similarly correlated and filtered, and the decorrelated signals are then latched in such a way as to account for the differential ionospheric refraction of the L1 and L2 signals. The bandlimited L2 signal is used to produce quadrature error signals related to phase difference between the L2 signal and a locally generated L2 replica. The error signals are integrated over an integration period which approximates the bit period of the unknown code, with the resulting estimates of the bits of the unknown code being combined with corresponding L1 channel code bit estimates weighted by a factor proportional to the difference in received L1 and L2 signal power. The hyperbolic tangent of each combined W-code bit estimate is then computed, with the result being multiplied by one of the integrated error signals. The resulting control voltage is then used to adjust the locally generated L2 carrier phase.
    • 一种全球定位系统(GPS)商业接收机,包括被设置为利用L1和L2 GPS卫星信号的能量的数字处理器,以便导出用于调制信号的未知安全码的估计。 在根据统计最大后验(MAP)估计理论处理来自接收到的L1和L2信号的信号能量时,所接收的L1信号与本地生成的P码的副本相关,并通过带通滤波器 带宽近似于未知调制码的带宽。 所接收的L2信号被类似地相关并被滤波,然后解相关的信号被锁存以便考虑L1和L2信号的差分电离层折射。 带限L2信号用于产生与L2信号和本地生成的L2副本之间的相位差有关的正交误差信号。 误差信号在近似未知码的位周期的积分周期内积分,未知码的比特的结果估计与相应的L1信道码比特估计组合,加权比例与接收到的L1的差值成正比 和L2信号功率。 然后计算每个组合的W码比特估计的双曲正切,结果乘以积分误差信号之一。 然后使用所得到的控制电压来调整本地产生的L2载波相位。

    • Providing access to an enterprise application from a telecommunications device via a client, through a device server, and an intermediate application gateway (IAG), is disclosed. The server is communication with the client and the IAG. The IAG and client are in indirect communication via the server. The client is operative to request an enterprise application token from the IAG using a dataset comprising a device identifier and a user identifier, without concurrently prompting a user for the dataset. The IAG is operative to prepare a token in response to the request, and push the token to an e-mail address associated with the telecommunications device via the server's push proxy gateway. The client is operative to employ the token in communications addressed to an enterprise application via the server and the IAG. The IAG is operative to replace the token in each communication with identification information called for by the enterprise application.
