Claim 16

The portable subscriber unit of claim 11 , wherein the processing system is further programmed to cooperate with the fixed portion to: keep a historical database of the location information; and access the historical database to determine the location information of the portable subscriber unit, when the location information has an age below a predetermined threshold.

Claim 17

The portable subscriber unit of claim 11 , wherein the request comprises a requested resolution for the location information, and wherein the processing system is further programmed to cooperate with the fixed portion to override the resolution preferred for the operation.

Claim 18

The portable subscriber unit of claim 11 , wherein the processing system is further programmed to cooperate with the fixed portion to: first determine and report the location information at a lower resolution than preferred; and then improve and report the resolution over time until reaching the resolution preferred.

Claim 19

The portable subscriber unit of claim 11 , wherein the processing system is further programmed to receive the request from a requester to send the location information to a recipient different from the requester, and cooperate with the fixed portion to send the location information to the recipient, in response to the request.

Claim 20

The portable subscriber unit of claim 11 , wherein the processing system is further programmed to receive the request from a requester to send the location information to the requester, and cooperate with the fixed portion to send the location information to the requester, in response to the request.

Claim 21

The portable subscriber unit of claim 11 , wherein the processing system is further programmed to: receive from a recipient of the location information a new request for the location information to be reported at a second resolution different from a first resolution at which the location information was initially sent; and cooperate with the fixed portion to determine and report the location information at the second resolution, in response to the new request.

Claim 22
