Abstract

A wireless communication system including a station having communication software for: (1) receiving a capability request from each of a plurality of non-emergency-service-providers, and (2) generating and transmitting a capability request response that includes a status indicator of a non-emergency-services position-determination (NESPD) capability of the station, wherein the NESPD capability of the station is user-selectable to enable or disable all NESPD irrespective of which of the plurality of non-emergency-service-providers is associated with the capability request. Additionally, a method of operating an element of a wireless communication network, comprising: (1) exchanging NESPD messages with a mobile station; (2) receiving a status indicator from the mobile station, at least indirectly, the status indicator indicating that the mobile station is configured to refrain from providing position information for non-emergency-services; and (3) preventing a plurality of NESPD messages from being transmitted to the mobile station in response to receiving the status indicator.

Claims

1. A wireless communication system, comprising:

a station having communication software for;

receiving a capability request from at least one non-emergency-service-provider; and

generating and transmitting a capability request response to each requesting non-emergency-service-provider,

wherein the capability request response includes a status indicator of a non-emergency-services position-determination (NESPD) capability of the station,

wherein the status indicator comprises no more than eight data bits of the capability request response, and

wherein the NESPD capability of the station is user-selectable to enable or disable all NESPD irrespective of which non-emergency-service-provider is associated with the capability request.

2. The wireless communication system of claim 1 wherein the capability request response further includes at least one of a GPS acquisition capability indicator and a position calculation capability indicator.

3. The wireless communication system of claim 1 wherein the station is a first station and the communication software is first communication software, the wireless communication system further comprising a second station having second communication software for generating and transmitting the capability request.

4. The wireless communication system of claim 3 wherein the second station comprises a position determining element.

5. The wireless communication system of claim 1 wherein the station is a wireless mobile device.

6. The wireless communication system of claim 1 wherein the station is selected from the group consisting of:

a cellular phone, a wireless enabled personal digital assistant, a wireless-enabled personal computer, a GPS device, and a pager.

7. The wireless communication system of claim 1 wherein the status indicator comprises one data bit of the capability request response.

8. A method of operating an element of a wireless communication network, comprising:

receiving a status indicator from a mobile station, at least indirectly, wherein the status indicator indicates that the mobile station is configured to refrain from providing position information for non-emergency-services, and wherein the status indicator comprises no more than eight data bits of a capability request response; and

preventing a plurality of non-emergency-services position-determination (NESPD) messages from being transmitted to the mobile station in response to receiving the status indicator.

9. The method of claim 8 further comprising receiving, at least indirectly, a message from a non-emergency-service-provider regarding a service that is dependent upon the mobile station'"'"'s position within the wireless communication network.

10. The method of claim 8 wherein the status indicator indicates whether the mobile station is configured to:

refrain from providing position information for all non-emergency-services;

or

provide position information for all non-emergency-services.

11. The method of claim 8 wherein the status indicator indicates whether the mobile station is configured to provide or refrain from providing position information for non-emergency-services in a manner independent of any particular non-emergency-service-provider.

12. The method of claim 8 wherein the element is a position determining entity.

13. The method of claim 8 wherein the status indicator is included in a message further containing native capability data of the mobile station.

14. The wireless communication system of claim 8 wherein the status indicator comprises one data bit of the capability request response.
