Abstract: A method of handoff for use at base sites (110) of a cellular telephone system for handing off from one of the base sites to another one of the base sites at least one of a plurality of cellular telephones (102) each transceiving data packets and sharing a cellular radio channel of the cellular telephone system, which channel may be packet-switched or digital. A handoff message is sent to one of the active ones of the plurality of cellular telephones in response to determined system loading or signal characteristic, as exemplified in FIG. 7.

Abstract: Handoff between coverage areas is achieved in a radiotelephone system coupled to standard wireline switches. Upon initiation of a radiotelephone call in one radio coverage area, a directory number and radio call identifier (203) are downloaded to the subscriber unit (101) from a fixed control unit (111) associated with the coverage area. When the subscriber unit determines a handoff to a target radio coverage area is desirable, it transmits the directory number and radio call identifier to another fixed control unit (113) associated with the target radio coverage area. This fixed control unit calls the directory number and is coupled to the first fixed control unit via the standard wireline switch (115, 117). The radio call identifier is then sent to the first fixed control unit to enable the proper connection for handoff.

Abstract: CE00028R 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 radio 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.

Abstract: 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 detec tion 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.

Abstract: 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.
