Method for mapping poor coverage areas
First Claim
1. In a wireless device, a method of creating a database of poor coverage areas in a wireless communication system, comprising:
- determining a coverage area corresponding to a location of the wireless device;
determining if a signal quality metric of a communication link in the coverage area drops below a signal quality threshold;
wherein if the signal quality metric is below the signal quality threshold designating the coverage area a poor coverage area and incrementing a poor coverage area counter corresponding to the poor coverage area and storing the coverage area as the poor coverage area in the database if the coverage area has not already been stored as the poor coverage area;
storing one or more previous coverage areas traversed by the wireless device prior to entering the poor coverage area;
calculating and storing a trajectory to the poor coverage area based on the one or more previous coverage areas and the poor coverage area; and
anticipating entry of the wireless device into the poor coverage area utilizing the trajectory to the poor coverage area.

Abstract
A method of creating a database of poor coverage areas (120) in a wireless communication system includes (100) determining if a signal quality metric (204) of a communication link (130) in a poor coverage area (120) is below a signal quality threshold (202) then incrementing a poor coverage area counter (210), if not, incrementing a good coverage area counter (212). Storing one or more previous coverage areas (138-140) traversed by wireless device (102) prior to entering the poor coverage area (120) and calculating a trajectory (136) to the poor coverage area (120) based on one or more previous coverage areas (138-140) and poor coverage area (120). Subsequently, anticipating entry of the wireless device (102) into the poor coverage area (120) utilizing the trajectory (136) to the poor coverage area (120) and alerting a user of wireless device (102).
