Abstract

A wireless communication system receives (402) a communication specifying a portable subscriber unit (122) for which the communication is intended, and further indicating an originator location at which an originator of the communication is positioned. The system determines (404) a recipient location at which the portable subscriber unit is positioned. The system then calculates (406) a distance between the originator location and the recipient location, and routes (412) the communication to the portable subscriber unit when the distance meets a distance criterion.

Claims

1. A method for prioritizing a communication in a wireless communication system serving a plurality of portable subscriber units, the method comprising the steps of:

receiving said communication, which specifies a first one of the plurality of portable subscriber units for which said communication is intended, and further indicates an originator location at which an originator of said communication is positioned;

determining a recipient location at which said first one of the plurality of portable subscriber units is positioned;

calculating a distance between said originator location and said recipient location;

routing said communication to said first one of the plurality of portable subscriber units when said distance meets a distance criterion;

computing a speed at which said first one of the plurality of portable subscriber units is moving;

comparing said speed with a speed threshold;

comparing said originator with a list of important originators associated with said first one of the plurality of portable subscriber units, in response to said speed exceeding the speed threshold; and

negating the routing step when said originator is not included in the list of important originators.

2. The method of claim 1,

wherein said communication includes an indicator controlled by said originator for indicating a priority of said communication, and

wherein the method further comprises the steps of:

computing a speed at which said first one of the plurality of portable subscriber units is moving;

comparing said speed with a speed threshold;

comparing said priority with a priority threshold, in response to said speed exceeding the speed threshold; and

negating the routing step when said priority is below the priority threshold.

3. The method of claim 1,

wherein said communication originates from a second one of the plurality of portable subscriber units, and

wherein the method further comprises the steps of:

assigning a priority to said communication, the priority based upon said originator location; and

processing said communication in accordance with said priority.

4. The method of claim 1, further comprising the step of sending said communication elsewhere when said distance does not meet the distance criterion.

5. A method for prioritizing a communication in a wireless communication system serving a plurality of portable subscriber units, the method comprising the steps of:

receiving said communication from one of the plurality of portable subscriber units;

determining a location at which the one of the plurality of portable subscriber units is positioned;

assigning a location context to said location;

designating a time period during which the location context is applicable;

assigning a priority to said communication, the priority based upon said location and upon the location context only during said time period; and

processing said communication in accordance with said priority.

6. The method of claim 5, wherein the location context is stored in at least one of:

a fixed portion of the system; and

the one of the plurality of portable subscriber units.

7. The method of claim 5, wherein the location context is identified to the one of the plurality of portable subscriber units from a short-range cell.

8. The method of claim 5, further comprising the step of

defining a request type for said communication;

wherein the step of assigning the priority comprises the step of basing the priority upon the request type.

9. A method for prioritizing a communication including an originator identifier for identifying an originator of said communication in a wireless communication system serving a plurality of portable subscriber units, the method comprising the steps of:

receiving said communication, which specifies one of the plurality of portable subscriber units for which said communication is intended;

computing a speed at which said one of the plurality of portable subscriber units is moving;

comparing said speed with a speed threshold;

comparing said originator identifier with a list of important originator identifiers associated with said one of the plurality of portable subscriber units when said speed exceeds the speed threshold;

routing said communication to said one of the plurality of portable subscriber units when said speed does not exceed the speed threshold; and

sending said communication to said one of the plurality of portable subscriber units when said originator identifier is included in the list of important originator identifiers.

10. The method of claim 9,

wherein said communication includes a priority indicator controlled by an originator of said communication for indicating a priority of said communication, and

wherein the method further comprises, before the routing step, the step of comparing said priority with a priority threshold, when said speed exceeds the speed threshold, and

wherein the routing step comprises the step of routing said communication to said one of the plurality of portable subscriber units when said priority is above the priority threshold.

11. The method of claim 9, further comprising the step of sending said communication elsewhere when said speed exceeds the speed threshold.
