1. A method in a wireless communication device, the method comprising:

transmitting a location request message from a mobile station to a network that the mobile station is in communication with;

determining that the network can not provide the requested location information to the mobile station, comprising receiving an error message at the mobile station from the network in response to the mobile originated location request, wherein the error message is one of “Type of Shape Not Support,” “MOLR Method not Support,” “SystemFailure,” “UnexpectedDataValue,” “DataMissing,” “FacilityNotSupported,” “SS-SubscriptionViolation,” or “PositionMethodFailure”;

storing an indicator at the mobile station that the network is not capable of providing the requested location information; and

suspending subsequent transmission from the mobile station of location request message to the network.

2. The method according to claim 1 , wherein the step of determining comprises receiving a message at the mobile station from the network that the request can not be fulfilled.

3. The method according to claim 1 , wherein the step of determining comprises the expiration of a timer at the mobile station and the requested information has not been received from the network.

4. The method according to claim 1 , creating a FALSE flag at the mobile station in response to the receipt of the error message received.

5. The method according to claim 1 , determining comprises receiving an error message at the mobile station from the network, the message containing a return error component.

6. The method according to claim 1 , wherein storing comprises creating a FALSE flag at the mobile in response to the receipt of the FACILITY NOT SUPPORTED message received.

7. The method according to claim 1 , further comprising the step of establishing communications with a second network that the mobile station is communicating with and

transmitting a location request to the second network from the mobile station.

8. The method according to claim 1 , further comprising

determining that a no response timer at the mobile station has expired; and

sending a location request to the network.

9. The method according to claim 1 , further comprising comparing stored information at the mobile station prior to sending a location request to determine whether or not the network has the capability to receive location requests.

10. The method according to claim 1 , wherein the mobile station location is determined by mobile-assisted location determination or by mobile-based location determination.

11. The method according to claim 1 , wherein the location request is a mobile originated location request (MOLR) message.

12. The method according to claim 1 , further comprising invoking a location request, from the mobile station, by sending a REGISTER message to the network containing a location services mobile originated location request (LCS-MOLR) invoke component.

13. The method according to claim 1 , further comprising associating the error message with a public land mobile network in a table stored in the mobile station.

14. The method of claim 1 , further comprising associating the error message with a mobile originated location request type.

15. The method according to claim 14 , where the mobile originated location request type is a location data request, a GPS assistance data request, location Estimate, Deciphering Key or transfer to third party.

16. The method according to claim 15 , wherein the location data type is an Enhanced Observed Time Difference data request or a OTDOA of data request.
