Abstract:
A method of controlling handoff of communications with a mobile station from a first radio transceiver to a second radio transceiver in a communication system having a common baseband processing unit operably connected to each of the radio transceivers, the method comprising the steps of:maintaining respective first and second voice paths with modulated signals uplinked from the first and second radio transceivers to the common baseband processing unit while communications with the mobile station are handed-off from the first radio transceiver to the second radio transceiver;monitoring both the first and second voice paths at the same time to determine which path is currently carrying uplinked voice data from the mobile station; androuting uplinked voice data carried by the second voice path from the mobile station through to a switching system operably associated with the communication system in response to the monitoring step determining that the second voice path is currently carrying uplinked voice data from the mobile station.
