Abstract

A wireless terminal is dynamically placed into a call coverage group based on the location of the wireless terminal. Similarly, a wireless terminal is dynamically removed from a call coverage group on the basis of the location of the wireless terminal. In addition, within a call coverage group, the position of a wireless terminal that is in communication with an auxiliary desktop unit is determined by a preassigned position within the call coverage group of the auxiliary desktop unit. The wireless terminal in communication with the auxiliary desktop unit is always assigned this preassigned location in the call coverage group. Other call coverage groups that are based on geographical location and where the wireless terminal is not communication with an auxiliary desktop unit have wireless terminals assigned into the call coverage path group based on a predefined algorithm.

Claims

1. A method for establishing call coverage groups, comprising the steps of:

determining a physical location for one of a plurality of wireless terminals by communication between the one of the plurality of wireless terminals and an auxiliary unit; and

inserting the one of the plurality of wireless terminals into a call coverage group based on the physical location of the one of the plurality of wireless terminals and communication between the one of the plurality of wireless terminals and the auxiliary unit.

2. The method of claim 1 wherein the step of inserting comprises the step of excluding designated ones of determined ones of the plurality of wireless terminals from the call coverage group.

3. The method of claim 2 wherein the step of excluding comprises the step of examining a table defining the wireless terminals to excluded from the call coverage group.

4. The method of claim 1 wherein the step of inserting further comprises the step of placing the one of the plurality of wireless terminals into the call coverage group in a preassigned position assigned to the auxiliary unit in response to the determination that the physical location for the one of the plurality of wireless terminals is identified with the auxiliary unit.

5. The method of claim 4 further comprises the step of removing the one of the plurality of wireless terminals from the preassigned position in the call coverage group upon communication being interrupted between the one of the plurality of wireless terminals and the auxiliary unit.

6. The method of claim 5 wherein the step of removing comprises the step of releasing the preassigned position for use by another one of the plurality of wireless terminals in the call coverage group.

7. The method of claim 6 wherein the step of determining the physical location comprises the steps of detecting physical location information by each of the plurality of wireless terminals;

and

transmitting the detected physical location information to a wireless switching system controlling the plurality of wireless terminals.

8. The method of claim 7 further comprises the step of transmitting the physical location information comprises the step of the auxiliary unit communicating physical location information to the one of the plurality of wireless terminals.

9. The method of claim 8 further comprises the step of transmitting the physical location information comprises the step of fixed units transmitting physical location information to other ones of the plurality of wireless terminals.

10. The method of claim 1 wherein the step of inserting further comprises the step of placing the one of the plurality of wireless terminals into the call coverage group in a position based on a predefined algorithm in response to the determination that the physical location for the one of the plurality of wireless terminals is identified with the fixed unit.

11. The method of claim 10 further comprises the step of removing the one of the plurality of wireless terminals from the position in the call coverage group upon the one of the plurality of wireless terminals no longer identifying the fixed unit.

12. The method of claim 11 wherein the step of removing comprises the step of releasing the position for use by another one of the plurality of wireless terminals in the call coverage group.

13. The method of claim 12 wherein the step of determining the physical location comprises the steps of detecting physical location information by the one of the plurality of wireless terminals from the fixed unit;

and

transmitting the detected physical location information to a wireless switching system controlling the plurality of wireless terminals.
