Methods and devices for reducing undesired signals in a communication environment. At least two distinct composite signals (X and X ) are transmitted from a first communication environment ( ). A noise coefficient of the first communication environment ( ) based on the at least two distinct composite signals (X and X ) is calculated. At least two noise canceling signals based on the noise coefficient are calculated. The at least two noise canceling signals are added to an incoming signal (Y ) from a second communication environment ( ) to produce at least two combined signals. The at least two combined signal are transmitted into the first communication environment ( ).

Method and system for reducing undesired signals in a communication environment

Methods and devices for reducing undesired signals in a communication environment. At least two distinct composite signals (X.sub.1 and X.sub.2) are transmitted from a first communication environment (260). A noise coefficient of the first communication environment (260) based on the at least two distinct composite signals (X.sub.1 and X.sub.2) is calculated. At least two noise canceling signals based on the noise coefficient are calculated. The at least two noise canceling signals are added to an incoming signal (Y.sub.3) from a second communication environment (280) to produce at least two combined signals. The at least two combined signal are transmitted into the first communication environment (260).

Method and system for reducing undesired signals in a communication

A target device (18) performs the steps of receiving a broadcast message via an out-of-band paging network (14) which message includes an identification of the sourcing device. The subscriber (18) automatically registers, responsive to the receipt of the broadcast message, with a local communication server (22) associated with an in-band communications network (12). The target subscriber (18) then uses the identification of the sourcing device (16) to respond to the communication from the sourcing device (16) to establish a communication path therewith through the local communication server (22). In a preferred embodiment, the target subscriber unit and method reside in an asynchronous transfer mode (ATM) network. In this manner, the present invention establishes a direct communication path between the local communications server (22) to which the target subscriber unit (18) is attached and the sourcing device (16) thereby minimizing network trafficking and inefficiency problems.
