ABSTRACT:
The invention provides an advisory alert indicating conditions are such that an ongoing telephone call involving a cellular telephone may be dropped due to insufficient signal strength. A decrease in signal strength over time that exceeds a specified percentage decrease provides the primary basis for triggering the advisory alert. This advisory alert warns one or more participants of the call of the possibility of the call ending due to low signal strength. The advisory alert provides for conclusion of the call before the call is lost, and/or lowers the frustration level associated with a call lost for an unknown reason.In operation, signal strength is assessed during a series of time intervals. Signal strength of consecutive time intervals is compared. If the percentage drop in signal strength exceeds a specified percentage, an advisory alert is effectuated. The criteria that trigger an advisory alert may be non-programmable, or is modifiable in programmable embodiments.
