ABSTRACT:
FIELD OF THE INVENTION
This invention relates in general to wireless communication systems, and more specifically to a method for prioritizing a communication in a wireless communication system.
BACKGROUND OF THE INVENTION
Call prioritization based upon location is becoming increasingly important. For example, time is money for many people, and dealing with phone calls or other messages takes time. Being able to route calls to alternate services, e.g., voice mail, on various criteria is becoming important to help control the effort expended on low-value communication.
Salespersons who cover large territories, business executives, and other mobile professionals may have preferences about callers with whom they wish to spend time that are dependent on where the mobile professional and the caller are located. Urgency of a mobile-generated call may be affected by the location of the caller. A mobile subscriber may not want to receive any low-priority calls while driving at high speed. Prior art wireless communication systems have not provided adequate solutions to such prioritization problems.
Thus, what is needed is a method for prioritizing a communication in a wireless communication system. Preferably, the method will allow prioritization based upon the relative locations of the caller and the intended recipient, further based upon the location of a calling portable unit, and further based upon the speed at which an intended portable recipient is moving.
SUMMARY OF THE INVENTION
An aspect of the present invention is a method for prioritizing a communication in a wireless communication system serving a plurality of portable subscriber units. The method comprises the steps of receiving the communication, which specifies a first one of the plurality of portable subscriber units for which the communication is intended, and further indicates an originator location at which an originator of the communication is positioned; and determining a recipient location at which the first one of the plurality of portable subscriber units is positioned. The method further comprises the steps of calculating a distance between the originator location and the recipient location, and routing the communication to the first one of the plurality of portable subscriber units when the distance meets a distance criterion.
Another aspect of the present invention is a method for prioritizing a communication in a wireless communication system serving a plurality of portable subscriber units. The method comprises the steps of receiving the communication from one of the plurality of portable subscriber units, and determining a location at which the one of the plurality of portable subscriber units is positioned. The method further comprises the steps of assigning a priority to the communication, the priority based upon the location; and processing the communication in accordance with the priority.
Another aspect of the present invention is a method for prioritizing a communication in a wireless communication system serving a plurality of portable subscriber units. The method comprises the steps of receiving the communication, which specifies one of the plurality of portable subscriber units for which the communication is intended; and computing a speed at which the one of the plurality of portable subscriber units is moving. The method further comprises the steps of comparing the speed with a speed threshold, and routing the communication to the one of the plurality of portable subscriber units when the speed does not exceed the speed threshold.
