Abstract
Abstract Geographic relationship between communication units (102, 103) within a communication system (100) can be achieved when a first communication unit transmits its location information. Upon receiving this location information, a second communication unit determines its location information. Having this information, the second communication unit then determines a geographic relationship between the two units and subsequently displays this information both visually and audibly.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
147 words
A method for determining a geographic relationship between communication units, the method comprising the steps of: transmitting, by a first communication unit, a speech message together with first location information of the first communication unit to a second communication unit; receiving, by the second communication unit, the speech message together with the first location information; determining, by the second communication unit, second location information of the second communication unit; determining, by the second communication unit, a geographic relationship between the first communication unit and the second communication unit based on the first location information and the second location information; and displaying, by the second communication unit, the geographic relationship and the speech message audibly to a user of the second communication unit by generating a multi-dimensional audible message, wherein the multi-dimensional audible message produces an acoustic perception of at least a directional component of the geographic relationship.
Claim 2
Independent Claim
147 words
A method for determining a geographic relationship between communication units, the method comprising the steps of: transmitting, by a first communication unit, a speech message together with first location information of the first communication unit to a second communication unit; receiving, by the second communication unit, the speech message together with the first location information; determining, by the second communication unit, second location information of the second communication unit; determining, by the second communication unit, a geographic relationship between the first communication unit and the second communication unit based on the first location information and the second location information; and displaying, by the second communication unit, the geographic relationship and the speech message audibly to a user of the second communication unit by generating a multi-dimensional audible message, wherein the multi-dimensional audible message produces an acoustic perception of at least a directional component of the geographic relationship.
Claim 3
Dependent Claim
31 words
The method of claim 1, wherein the step of transmitting further comprises the step of transmitting velocity, directional heading, and location coordinates as at least part of the first location information.
Claim 4
Dependent Claim
28 words
The method of claim 1, wherein the step of displaying further comprises the step of displaying the geographic relationship visually to the user of the second communication unit.
Claim 5
Dependent Claim
34 words
The method of claim 2, wherein the step of determining second location information further comprises the step of determining velocity, directional heading, and location coordinates as at least part of the second location information.
Claim 6
Dependent Claim
66 words
The method of claim 4, wherein the step of displaying further comprises the step of visually displaying the geographic relationship to the user of the second communication unit as a vector, wherein the vector is derived from the velocity, the directional heading, and the location coordinates of the first communication unit and the velocity, the directional heading, and the location coordinates of the second communication unit.
Claim 7
Independent Claim
118 words
A method for a first communication unit to determine a geographic relationship between the first communication unit and a second communication unit, the method comprising the steps of: receiving first location information and a speech message from the second communication unit; determining second location information for the first communication unit; determining a geographic relationship between the first communication unit and the second communication unit based on the first location information and the second location information; and displaying the geographic relationship and the speech message audibly to a user of the first communication unit by generating a multi-dimensional audible message, wherein the multi-dimensional audible message produces an acoustic perception of at least a directional component of the geographic relationship.
Claim 8
Independent Claim
118 words
A method for a first communication unit to determine a geographic relationship between the first communication unit and a second communication unit, the method comprising the steps of: receiving first location information and a speech message from the second communication unit; determining second location information for the first communication unit; determining a geographic relationship between the first communication unit and the second communication unit based on the first location information and the second location information; and displaying the geographic relationship and the speech message audibly to a user of the first communication unit by generating a multi-dimensional audible message, wherein the multi-dimensional audible message produces an acoustic perception of at least a directional component of the geographic relationship.
Claim 9
Dependent Claim
31 words
The method of claim 6, wherein the step of receiving further comprises the step of receiving velocity, directional heading, and location coordinates as at least part of the first location information.
Claim 10
Dependent Claim
34 words
The method of claim 7, wherein the step of determining second location information further comprises the step of determining velocity, directional heading, and location coordinates as at least part of the second location information.
Claim 11
Dependent Claim
66 words
The method of claim 8, wherein the step of displaying further comprises the step of visually displaying the geographic relationship to the user of the first communication unit as a vector, wherein the vector is derived from the velocity, the directional heading, and the location coordinates of the first communication unit and the velocity, the directional heading, and the location coordinates of the second communication unit.
Claim 12
Independent Claim
111 words
A method for a dispatch station to determine a geographic relationship between a communication unit and the dispatch station, the method comprising the steps of: receiving first location information and a speech message from the communication unit; ascertaining second location information of the dispatch station; determining a geographic relationship between the dispatch station and the communication unit based on the first location information and the second location information; and audibly displaying the geographic relationship and the speech message simultaneously to a user of the dispatch station by generating a multi-dimensional audible message, wherein the multi-dimensional audible message produces an acoustic perception of at least a directional component of the geographic relationship.
Claim 13
Independent Claim
111 words
A method for a dispatch station to determine a geographic relationship between a communication unit and the dispatch station, the method comprising the steps of: receiving first location information and a speech message from the communication unit; ascertaining second location information of the dispatch station; determining a geographic relationship between the dispatch station and the communication unit based on the first location information and the second location information; and audibly displaying the geographic relationship and the speech message simultaneously to a user of the dispatch station by generating a multi-dimensional audible message, wherein the multi-dimensional audible message produces an acoustic perception of at least a directional component of the geographic relationship.
Claim 14
Dependent Claim
31 words
The method of claim 10, wherein the step of receiving further comprises the step of receiving velocity, directional heading, and location coordinates as at least part of the first location information.
Claim 15
Dependent Claim
54 words
The method of claim 11, wherein the step of displaying further comprises the step of visually displaying the geographic relationship to the user of the dispatch station as a vector, wherein the vector is derived from the second location information and the velocity, the directional heading, and the location coordinates of the communication unit.
