Abstract: There is disclosed a power control circuit for controlling the combined effective DC bias current of a bank of parallel RF power amplifiers disposed in the transmit path of an RF transmitter. The power control circuit comprises: 1) a first signal monitor for monitoring the level of a modulated RF output signal; and 2) an amplifier bias current controller for comparing the modulated RF output signal level and a known maximum output power parameter of the active RF power amplifiers to determine if the active RF power amplifiers are operating in the linear region. If the active RF power amplifiers are operating in or near the nonlinear region, the power control circuit enables one or more inactive RF power amplifiers to increase the effective combined DC bias current and linearity of the active RF power amplifiers.

Abstract: A multi-site dispatch communication network includes a hub controller programmed to expedite the connection between multiple radio cells to accomplish a broadcast of the radio transmission. A routing table is employed to provide an association between the various group identification codes and the respective mobile radio cell sites servicing members of the group. A connection table is employed to identify the resources utilized in the dispatch communication connection. When a dispatch communication is initiated, the routing table is accessed to determine which mobile radio cell sites service the various members of the group. When a connection is made to establish the dispatch communication, the connection table is written with information concerning the resources utilized to complete the dispatch communication. In this manner, dispatch communications can be quickly established and terminated. The resources of the network are thereby optimized.

Abstract: Automatic facility information transfer to remote locations in cross-connect systems is accomplished by providing limited telephone services to wired premises not having permanent telephone service by enabling 911 calls, calls requesting permanent service, operator-assisted telephone company credit card calls, and calls to repair/maintenance centers from personnel in the field. In response to off-hook conditions at prospective subscriber premises or service personnel handsets connected to cable pairs in the field, limited telephone services are provided by a matrix system. Cable pair designations and the dialed telephone number are ascertained to respectively access a database and look-up table to retrieve facility information and protocol information for subsequent transmission of the calling line telephone number and facility information to a paging system.

Abstract: A technique is disclosed for traffic management in spread spectrum wireless telecommunications systems using different admission control levels different frequency layers. In an embodiment of the invention, the capacity on a first frequency, having a specific admission control level, is permitted to increase to the point where the development of coverage holes occurs due to the effects of cell breathing are present. This is compensated for by maintaining a designated frequency that is free from coverage problems by applying a stricter admission control relative to the first frequency. Thus calls or new access attempts affected by coverage problems on the first frequency are diverted to the designated frequency. The method improves overall network capacity and call quality in the network by more efficiently utilizing spectral resources.

Abstract: The present method for reducing latency in satellite communication includes the steps of applying, at a first earth terminal, a discriminator to user data. The discriminator delineates action data and forward data, thereby forming delineated user data. The action data represents data to be processed on board a satellite, while the forward data represents data to be forwarded through the satellite without processing. At the satellite, the delineated user data is partitioned into the action data and the forward data. The satellite then processes the action data to form processed action data and transmits, if necessary, the processed action data from the satellite. During processing of the user data, the satellite may generate result data in response to the action data and may transmit the result data alone or appended to the processed action data. Furthermore, the satellite may store a world model in a memory onboard the satellite.

A transmitter calibration path associated with each antenna element extends from the transmit port of the associated transceiver unit to the associated antenna element, from the associated antenna element to the calibration element, and from the calibration element to the receive port of the calibration unit.

Abstract: A communications system that uses electromagnetic waves. The communications system preferably operates in the millimeter-wave frequencies, and provides relatively high signal restoration and isolation. The communications system can use polarization diversity to increase the capacity of a channel. Isolation and restoration features in the transceivers eliminate or reduce the effects of precipitation and/or reflection and diffraction from objects, and thus is well-suited for an urban environment. The transceiver will select the proper antenna and signal path for optimal information throughput as the conditions in the propagation medium of the network vary.

Abstract: A method for controlling transmit power for connections between a base station and mobile stations of a radio communications system includes the steps of designating a direction of transmissions from mobile stations to a base station as an upward direction, and designating a direction of transmissions from the base station to the mobile stations as a downward direction. Information is transmitted to the mobile stations in the downward direction simultaneously in one frequency channel. Received powers are determined at at least two of the mobile stations. A dynamic range of transmit powers for the frequency channel is set. Transmit powers for the base station are determined. The determined transmit powers are mobile-station-specific by taking the received powers into account. A minimum transmit power is at least equal to a maximum transmit power minus the dynamic range. A device for controlling the transmit power is also provided.

Abstract: A redialing apparatus for a portable telephone includes a channel disconnection detection section, an on-hook processing section, a call determination section, and a redial processing section. The channel disconnection detection section monitors a communication state during communication to detect a channel disconnection. When the channel disconnection detection section detects a channel disconnection, the on-hook processing section executes on-hook processing. When the channel disconnection detection section detects the channel disconnection, the call determination section determines whether a call during communication is an outgoing call or an incoming call. When the call determination section determines that the call is an outgoing call, the redial processing section executes redial processing on the basis of calling information used for calling processing of the call during communication.

Abstract: In a satellite communication system where user terminals 11 communicate via satellites 9A-E with earth stations 7A-E to join with a terrestrial telephone network 1, a controller 18 at a master earth station 7A monitors all earth stations 7A-E for a request for service received from a user terminal 11, then calculates which earth station 7A-E is best placed to service the request and instructs the best placed earth station 7B to service the request. In servicing the request, the best placed earth station 7B uses that earth station 5C whereat the user terminal 11 is registered as a visitor as the gateway into the terrestrial system 1 by routing all voice grade messages thereto and therefrom via a voice link 21. If the user terminal 11 is not registered at any earth station 7A-E, the best placed earth station becomes the earth station of registration and acts as a gateway.

Abstract: A method and apparatus for controlling roaming in a multiple service provider environment. When a mobile station determines that it can no longer obtain acceptable service from a primary service provider, the mobile station determines whether it is operating at the periphery of the primary service provider coverage area. If it is, then the mobile station is permitted to obtain service from a secondary service provider (i.e. roam). If it is determined that the mobile station is not operating at the periphery of the primary service provider coverage area, then the mobile station is prevented from roaming for a time period which allows the mobile station to emerge from a presumed coverage hole.

Abstract: A radio base station receiving data transmission system is provided for uplink site diversity of a mobile communication system that is configured by a mobile station, radio base stations, a base station control device and a mobile communication exchange. Herein, the mobile station establishes the uplink site diversity using the radio base stations under control of the base station control device. Now, each of the radio base stations that are connected to the mobile station to receive its signals performs error detection on receiving data thereof so as to produce error information with respect to each frame. The error information contains error detection information representing occurrence of error in the receiving data and an error frequency representing a degree of error contained in the receiving data. Firstly, the base station control device receives the error information from each of the radio base stations regarding the uplink site diversity.

Abstract: A mobile station position estimation scheme for a cellular mobile communication system which is capable of estimating a position of a mobile station in a simple manner even in the general cellular mobile communication systems in which base stations are not synchronized. According to this mobile station position estimation scheme, a first signal sequence and a second signal sequence which are uniquely predetermined for the mobile station are exchanged between the mobile station and the base station, and then a position of the mobile station is estimated at one station among the base station and the mobile station, by obtaining a phase difference between the first signal sequence and the second signal sequence and calculating an estimated distance between the base station and the mobile station according to the phase difference.

Abstract: A method for avoiding unnecessary signalling in a cellular system is disclosed whereby a “VMSC data generation” or similar field of information can be utilized in an HLR queue. When the HLR is storing Location Erasure data in the queue, the HLR can also store the most current “VMSC data generation” field together with the Location Erasure data in the queue. Prior to sending a Location Erasure message to a VMSC from the HLR's queue, the HLR determines whether the current “VMSC data generation” field is different than the one stored in the queue. If so, the HLR can discard the Location Erasure data in the queue, and thus defer from sending the Location Erasure message to that VMSC. Alternatively, when the HLR notes a new “VMSC data generation” field, the HLR scans the complete queue and discards all Location Erasure messages associated with an older “VMSC data generation” field than the current one noted by the HLR.
