摘要： A cellular radiotelephone system transfers a call from a source base-site (200) to one target base-site (205,210). A source base-site (200) in the first RF coverage area (100) measures the signal strength (RSSI.sub.S) of a mobile (225), provides a forecasted signal strength (RSSI.sub.F) representing a would-be power increase of the mobile (225) and sets up two time windows. The source base-site (200) sends the measured and forecasted signal strengths to candidate target base-sites (205,210) found by the mobile (225) which measure the mobile (225) signal strength (RSSI.sub.T) and compare it once to RSSI.sub.S plus a hysteresis value. If RSSI.sub.T is greater than RSSI.sub.S, the call is transferred to the best responding cell. If RSSI.sub.T is below RSSI.sub.S, RSSI.sub.T is compared to RSSI.sub.F. During this time, the mobile 225 will increase power at the end of the first time window. If RSSI.sub.T is ever greater than RSSI.sub.F at any of the candidate target base-sites (205,210), the call is transferred to the responding target base-site (205,210). If the source base-site (200) receives no responses during the second time window, the process ends.

摘要： Remote units (113) having large amounts of data to transmit will be dynamically assigned Orthogonal Variable Spreading Factor (OVSF) codes corresponding to higher data rates and remote units (113) with lower amounts of data to be transmitted will be assigned OVSF codes corresponding to lower data rates. Additionally, in an alternate embodiment of the present invention, once system interference becomes greater than a predetermined threshold, the data rate between the base station (100) and remote units (113) in communication with the base station (100) is reduced. The reduction of the data rate between the base station (100) and remote units (113) occurs by changing the current OVSF codes utilized by both the remote units (113) and the base station (100).

摘要： A method and detector are described for detecting a data signal including at least three repeated data words each preceded by a Barker word. The detector includes a microcomputer that is responsive to interrupt and correlation programs for receiving and timewise correlating the repeated data words in the data signal. Upon detection of each Barker word, the microcomputer stores the following data word and measures the elapsed time interval between data words by measuring the time between detection of Barker words. The elapsed time interval between the previously and presently received data words is added to the stored time interval of all previously received data words. If at least three of the received data words have corresponding stored time intervals that are correlated with predetermined time interval ranges, a correlation indication signal is provided to indicate that valid data words have been received. The inventive method and detector may be advantageously utilized in mobile and portable stations of a radio communication system for receiving high speed data on a noisy voice channel.

摘要： During data transmission to a remote unit (113) utilizing a supplemental, high-speed data channel (105), data transmission stops due to all data being communicated to the remote unit (113) or because of an interruption in transmission. In the situation where all data has been transmitted to the remote unit (113) the remote unit (113) will drop the supplemental channel (105) prior to acknowledging reception of the last frames transmitted, and acknowledgment will take place utilizing the low-speed fundamental channel (103). In the situation where an interruption occurs, data transmission will continue utilizing a fundamental channel (103) if less than a predetermined amount of data remains to be transmitted.

摘要： A method is provided of allocating channels in a trunked radio frequency communication system having a plurality of channels, each with a channel rate. The method includes the steps of transmitting channel characteristics on idle channels of the plurality of channels by a base site. Idle channels are then scanned for channel characteristics by a communication unit. The method also includes the step of seizing an idle channel, by the communication unit, based, at least in part, upon the channel characteristics.

摘要： Remote units (113-117) that wish to receive a multicast session, monitor a multicast advertisement message on a system broadcast channel to determine a session to receive. Once a remote unit (113-117) requests participation in the multicast event, a common supplemental channel (205) is assigned to the remote unit (113-117), and the multicast session is broadcast to all remote units (113-117) currently participating in the multicast event. The common supplemental channel (205) utilizes two unique spreading codes for channel assignment, with one of the spreading codes being a function of the multicast session address (501) that is broadcast by the server (120).

摘要： A digital radiotelephone system requiring a transfer of communication from a source base-site (200) in a source cell (100) to a selected one target base-site in a target cell. A source base-site (200) in the source cell (100) provides a first and a second threshold and measures the received signal strength of a mobile unit (225) communicating to the source base-site (200). When the measured signal strength at the source base-site (200) falls below the first threshold, the source base-site (200) initiates a handoff to target base-sites located by the mobile unit (225). The target base-sites measure the received signal strength of the mobile unit (225) and a target base-site is selected. The source base-site (200) is notified of the selected target base-site and hands off communication of the mobile unit (225) to the selected target base-site when the previously measured signal strength at the source base-site (200) falls below the second threshold.

摘要： A unique packet-switched cellular telephone system includes a cellular switch (140) and base sites (110) for providing packet-switched data services to cellular data telephones (102). Cellular switch (140) includes packet access points (152, 153) coupled to a packet network and T1 span lines (160, 161) coupled to the landline telephone network. Base sites (110) are coupled to cellular switch (140) by T1 span lines (164, 165) in which all time slots are clear channels and one time slot is dedicated for common channel signalling. Multiple data calls are assigned to each packet-mode radi channel thereby conserving valuable radio channel spectrum. Data calls are handed off from one packet-mode radio channel to another on the basis of cellular data telephone movement, signal strength, and/or bit-error rate, or on the basis of radio channel data packet capacity, data packet traffic, and/or data packet throughout.

摘要： An improved multiprocessor bus arbiter which provides dynamically prioritized access for a plurality of processors to shared peripheral devices on a common bus through bus access switches. The arbiter includes logic circuitry to which incoming bus access request signals are coupled and a memory means which stores bus access status. The logic circuit determines bus access based on the input request signal and the stored information. The arbiter is adapted to provide a cycle shared mode of access or a lock out mode of access, as may be required.
