Abstract: The invention concerns a connection method for a number of cellular telephones where each cellular telephone receives and transmits data packets and shares a digital cellular radio channel in a cellular telephone system. According to the invention errors are monitored in the data packet received from each of the cellular telephones which share the digital cellular radio channel to determine the bit error rate of the channel, the signal strength of each cellular telephone is determined for the digital cellular radio channel and a connection message is sent to a cellular telephone when the determined signal strength is less than a predetermined signal strength and the determined bit error rate exceeds a predetermined bit error rate.

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: WIRELESS PBX SYSTEM USING FREQUENCY SCANNER FOR CHANNEL IDENTIFICATION In a wireless private branch exchange, communication network, a method and apparatus are offered for identifying network communication resources. The method includes the steps of measuring a signal quality factor of a channel of a selected spectrum and comparing the measured values with a threshold value. The method further includes the step of selecting channels, exceeding the threshold, as network communication resources. The selected spectrum is that, also used, by a local cellular communication network. Where scanning determines that a channel is not being used by the cellular system then use is permitted with the private system.
