  • Patent number: 6853842
    Abstract: A system and method collects radio frequency isolation values with the assistance of mobile stations operating within a cellular wireless communication system. A broadcast channel and a broadcast cell/sector are first chosen. Then, the broadcast channel is disabled in neighboring (or all) other cells/sectors in the system. The base station servicing the broadcast cell/sector then transmits on the broadcast cell sector. Mobile stations operating within the system are then directed to measure and report the signal strength of the broadcast channel as well as a traffic channel servicing their ongoing calls. The mobile stations then report these signal strengths to the cellular wireless communication system. The signal strength measurements are then used to calculate cell/sector radio frequency isolation values between the broadcast cell/sector and respective servicing cell/sectors.

  • Patent number: 6442157
    Abstract: A system and method for quality-driven channel selection in a communication network that measures interference on idle and active voice channels in a first quality-driven channel selection (QCS) cell is disclosed. A voice channel queue is automatically ordered based on a clearest voice channel which is determined by a reverse bit error rate (RBER) measurement and a forward bit error rate (FBER) measurement on the active voice channels and by an idle noise measurement on the idle voice channels. Further, dynamic channel sets (DCS) are created from the voice channel queue based on the RBER, FBER, and idle noise received, where the DCS are queues that include low interference channels and moderate interference channels.
