ABSTRACT:
A system for monitoring and adapting radio signals at a cellsite to enable improved call management for mobiles active therein. Matrix switches, advantageously separate ones for the receive side and the transmit side of the cellsite's radios, have extra ports to which other devices are connected. These devices include signal modifiers such as amplifiers, filters, attenuators or interference cancelers, through which the radio signals may be routed within the switches to enable modification of the signals on a per-channel basis. These devices further include signal generators which may inject signals such as tones or noise to ports in the switches to create pretextual radio conditions that may trigger desired call management results. An air interface controller, advantageously in combination with a cell neighborhood host controller, governs operation of the system. The controller includes a message player whose prerecorded messages may be patched through to a land line party to notify that the mobile party has entered a blackout zone.
