  • Method of switching a channel from a first propagation path to a second propagation path
    Patent number: 5995807
    Abstract: The invention provides a method of switching a call set up between a first station and a second station from a current propagation path to a following propagation path. The method includes the following steps:a value representative of signal-to-noise ratio is measured for each of said propagation paths, namely the current path and the following path; andthe first station switches the call from a current channel on the current propagation path to a following channel on a following propagation path as a function of values representative of signal-to-noise ratio measured respectively for said current propagation path and for said following propagation path. In the method:the following call channel is reserved for said call; and:in said second station, said call is switched from the current channel to said following channel in response to said call failing to be received in the current channel.
