Patent ID: 7933599

Claim:
A computer-implemented method for communications handoff, the computer-implemented method comprising: obtaining position information of a communication device; obtaining position information of a target base station attempting to acquire a signal from the communication device; calculating a direction of the communication device relative to the target base station; directing a directional antenna of the target base station in the direction of the communication device; determining a perceived carrier frequency of the communication device at the target base station; adjusting a searched frequency of the target base station to compensate for a frequency shift resulting from a Doppler shift of a transmitted carrier frequency from the communication device; increasing a pilot channel power of the communication device if the communication device is not acquired by the target base station after a time period; and reducing a transmission rate of the communication device wherein a total transmitted power of the communication device after increasing the pilot channel power is maintained at a value substantially equal to a total transmitted power of the communication device prior to commencing the communications handoff.
