    摘要: A data signalling system for transmitting signals between at least one primary station and a plurality of secondary stations. The system is well adapted for use in multiple unit radio communications systems capable of noise and data communications. A register model is utilized which permits a highly flexible signalling system compatable with a wide range of communications networks. Data transfer is accomplished using fixed length data packets which are error correction encoded and transmitted utilizing PSK modulation.

    摘要: A node within a communication system periodically broadcasts its interference status to neighboring nodes within the communication system. Additionally, the node receives an interference status from all neighboring nodes. If communication is desired with a neighboring node, the node accesses the stored table for the particular neighboring node and determines an optimal time for transmission to the neighboring node. This is accomplished by utilizing the table received from the neighboring node and determining the neighboring node's optimal times for reception.

    摘要: In accordance with the principles of the present invention, a method and apparatus for filtered wireless communications is provided. The method provides a filtered wireless zone. Signaling channels normally serving a geographic vicinity are scanned, with the channel identity and the system identity of each signaling channel recorded. A transmitter-receiver is commanded to such channel. A signaling channel marker is radiated. A new signaling channel assignment message is sent, sending handsets to a new capture channel. An appropriate signal is radiated to keep the handsets locked to the new capture channel. The transmitter-receiver then ceases radiating on the first channel, and proceeds to the second external signaling channel previously recorded. The transmitter-receiver repeats this process for all the external signaling channels previously located.

    摘要: Methods and devices for reducing undesired signals in a communication environment. At least two distinct composite signals (X1 and X2) are transmitted from a first communication environment (260). A noise coefficient of the first communication environment (260) based on the at least two distinct composite signals (X1 and X2) is calculated. At least two noise canceling signals based on the noise coefficient are calculated. The at least two noise canceling signals are added to an incoming signal (Y3) from a second communication environment (280) to produce at least two combined signals. The at least two combined signal are transmitted into the first communication environment (260).

Each of the ATM channels supports communication though ATM cells over a common frequency band. At least one ATM node (21) is coupled to the base stations. A base station controller (11) is coupled to the ATM node. The base station controller has a combiner (303) for combining cell streams received from the first and second base stations and an ATM signalling circuit (330) for sending ATM commands to the ATM node for dividing cell streams at the ATM node to the first and second base stations. The remote station (30) has a logic unit (520) for combining cell streams received from the first and second base stations during a handoff from the first base station to the second base station.

    摘要: A method of operation of a network (10) of radio stations (e.g. 11, 12 and 13) in which each radio station communicates with at least two other radio stations. A message (32) is sent and a corresponding reply (35) is received between first and second stations (11 and 12). Similar messages are sent between second and third stations (12 and 14) and the first and third stations (11 and 14). A time delay is measured between sending of each message and receiving the corresponding reply. Distances are calculated between each station and each other station and, from the distances, locations for the second and third stations relative to the first station are calculated.

    摘要: A wide bandwidth frequency discriminator circuit (200) employs a wide bandwidth limiting amplifier (202) to amplify the IF signal portion of a received RF signal. A frequency-to-voltage circuit 208 is provided having a bandwidth substantially greater than the bandwidth of the IF signal. This discriminator (200) operates to form a detection system capable of discriminating between desired and undesired components of the received RF signal even when said desired and undesired components are nearly identical in amplitude. This is due in part to the enhanced frequency response provided by the discriminator (200).

    摘要: A target device (18) performs the steps of receiving a broadcast message via an out-of-band paging network (14) which message includes an identification of the sourcing device. The subscriber (18) automatically registers, responsive to the receipt of the broadcast message, with a local communication server (22) associated with an in-band communications network (12). The target subscriber (18) then uses the identification of the sourcing device (16) to respond to the communication from the sourcing device (16) to establish a communication path therewith through the local communication server (22). In a preferred embodiment, the target subscriber unit and method reside in an asynchronous transfer mode (ATM) network. In this manner, the present invention establishes a direct communication path between the local communications server (22) to which the target subscriber unit (18) is attached and the sourcing device (16) thereby minimizing network trafficking and inefficiency problems.
