Local control mechanism for automatically parking active combiner filter

摘要

The local control mechanism for automatically parking an active combiner filter and activating an alternate combiner filter in an auto-tune combiner in a radio telecommunications network, is resident entirely at a remote base station and comprises a device for sampling the radio frequency (RF) energy level on the active combiner filter. A device determines whether the sampled RF energy level exceeds a predetermined RF energy threshold. A device determines the number of RF energy samples taken, and a device for parking the active combiner filter and activating the alternate combiner filter. Devices are provided for varying the predetermined RF energy threshold, and for setting a trigger number of RF energy samples.
