    摘要： A method and an apparatus provide for controlled access to a shared communication medium. Time slots on a forward channel include information regarding status useful for remote units to determine whether a reverse channel is available for seizure. Additionally, information along the forward channel provides guidance to the remote units to control attempts to seize the reverse channel. In one embodiment a remote unit divides a data package into a plurality of portions and attempts to seize the reverse channel using a single portion of the data package which corresponds to one time slot on the reverse channel. It then waits until it receives notification along the forward channel that the first data portion was successfully received before it attempts to send any of the remainder of its data in consecutive time slots on the reverse channel.

    摘要： A method and system of the present invention updates a replicated database of a telecommunications network system. A call transport system forwards calls from a local telephone station to a destination. A signaling system is operatively connected to the call transport system and includes primary site databases containing customer records for call routing and other signaling functions and at least one secondary site database containing the customer records of the primary site database. Both primary and secondary site databases maintain multiple versions of the same customer record so that queries of a call can use a version number to access the corresponding version of the record in the same database for consistent routing and other signaling information. A customer record is updated in the primary site database and that information is transmitted through the signaling network to the secondary site database containing the replicated version of the record. The records are then updated according to the sequence of the version number. The processing of all calls querying the previous version of the primary and secondary site database record is completed before the previous version of the database record is deleted.

    摘要： A system and method for predicting future interference power in packet-switched networks is disclosed, allowing improved performance in such networks via optimized link adaptation and power control. In an embodiment for use in a cellular network, Kalman filtering can be used to provide the interference estimation through identification of the number of active co-channel interferers in the cellular networks and correlation of the interference power with the number of active interferers. A two-dimensional Kalman filter can be used to exploit that correlation to enhance prediction accuracy. In an alternative embodiment, a one-dimensional Kalman filter can be used where the number of active interferers is not considered.

    摘要： A method and apparatus to enable IP networking for mobile hosts without requiring changes to be made to the TCP/IP stack in the operating system installed on the mobile hosts. The apparatus is an “intelligent device” that can be installed on or connected to a mobile host, and may comprise a software-only logical module, physical hardware, or a combination of both. To a mobile host, the intelligent device emulates a network interface such as an Ethernet card or a telephone modem. The intelligent device appears to an access network just like any regular IP host connected to the access network through a physical network interface device. The intelligent device handles all mobile networking functions for the mobile host, and may control multiple different physical network interface devices to enable a connection to the “best” access network available to the mobile user at his location.
