Abstract
Location determination signals are received and a location of interest is determined from the location determination signals. A communication service with a known, valid base station via a first communication channel is established and synchronized. A first rate of rise of a signal strength indicator associated with the first communication channel is monitored and a second rate of rise of a signal quality indicator associated with the first communication channel is also monitored. When at least one of the first rate rises at a rate greater than a first predetermined threshold rate and the second rate rises at a rate greater than a second predetermined threshold rate, a warning message is transmitted to the known, valid base station before synchronization of the communication service is lost with the known, valid base station.
