Abstract:

A method for tracking call failures on a cellular phone, the method comprising: monitoring on a cellular phone outbound calls made on the phone; determining on the phone whether a call failure for an outbound call occurs only prior to the call being connected to the cellular communication carrier's network; in response to determining that a call has failed prior to the call being connected to the cellular communication carrier's network, storing information relating to the call failure on the phone; and sending the information to a communication carrier that provides cellular telecommunication services for the phone, wherein the information sent to the carrier includes a percentage or number of outbound calls over a time interval that have been successfully or unsuccessfully connected to the carrier's network and wherein such percentage or number data is organized by cell ID to enable the carrier to identify the cells in the carrier's network that fail the most.
