receiving, at a time before the location data is needed, a Measure Position Response message comprising the location data.

2. The method of claim 1, wherein the network response time comprises a value representing a shortened response time of not greater than 4 seconds.

3. The method of claim 1, wherein the network accuracy comprises a value representing low accuracy of not less than 100 meters.

4. The method of claim 1, wherein the Measure Position Request comprises no Assistance Data.

5. The method of claim 1, further comprising:

transmitting an Assistance Data message; and

receiving an Assistance Data Ack message.

6. The method of claim 1, wherein the Measure Position Request message comprises an RRLP Measure Position Request message.

7. The method of claim 1, wherein the Measure Position Response message comprises an RRLP Measure Position Response message.

8. A method of reducing rebids of Measure Position Request messages between a network and a mobile station in a wireless network, the method comprising:

transmitting an RRLP Assistance Data message;

receiving an RRLP Assistance Data Ack message;

waiting until a predetermined time, wherein the predetermined time is based on a time location data is needed;

transmitting, at the predetermined time, RRLP Measure Position Request message comprising a network response time and a network accuracy, wherein the network response time comprises a value representing a shortened response time of not greater than 4 seconds, wherein the network accuracy comprises a value representing low accuracy of not less than 100 meters, and wherein the RRLP Measure Position Request message comprises no Assistance Data; and

receiving, at a time before the location data is needed, a RRLP Measure Position Response message comprising the location data.

9. A network for reducing rebids of Measure Position Request messages between the network and a mobile station in a wireless network, the method comprising:

a timer to wait until a predetermined time, wherein the predetermined time is based on a time location data is needed;

a transmitter to transmit, at the predetermined time, Measure Position Request message comprising a network response time and a network accuracy; and

a receiver to receive, at a time before the location data is needed, a Measure Position Response message comprising the location data.

10. The network of claim 9, wherein the network response time comprises a value representing a shortened response time of not more than 4 seconds.

11. The network of claim 9, wherein the network accuracy comprises a value representing low accuracy of not less than 100 meters.

12. The network of claim 9, wherein the Measure Position Request comprises no Assistance Data.

13. The network of claim 9, wherein the Measure Position Request message comprises an RRLP Measure Position Request message.

14. The network of claim 9, wherein the Measure Position Response message comprises an RRLP Measure Position Response message.

15. A computer-readable product comprising a computer-readable medium comprising:

code for causing at least one computer to wait until a predetermined time, wherein the predetermined time is based on a time location data is needed;

code for causing at least one computer to transmit, at the predetermined time, Measure Position Request message comprising a network response time and a network accuracy; and

code for causing at least one computer to receive, at a time before the location data is needed, a Measure Position Response message comprising the location data.

16. The computer-readable product of claim 15, wherein the network response time comprises a value representing a shortened response time not greater than 4 seconds.

17. The computer-readable product of claim 15, wherein the network accuracy comprises a value representing low accuracy not less than 100 meters.

18. The computer-readable product of claim 15, wherein the Measure Position Request comprises no Assistance Data.

19. The computer-readable product of claim 15, wherein the computer-readable medium comprising further comprises:

code for causing at least one computer to transmit an Assistance Data message; and

code for causing at least one computer to receive an Assistance Data Ack message.

20. The computer-readable product of claim 15, wherein the Measure Position Request message comprises an RRLP Measure Position Request message.

21. The computer-readable product of claim 15, wherein the Measure Position Response message comprises an RRLP Measure Position Response message.

22. A method, in a network, for minimizing rebids between the network and a mobile station in a wireless network, the method comprising:

sending a Request message thereby opening a session in the mobile station;

determining, while the session is open, an RR message is ready to be sent to the mobile station;

avoiding aborting the session with the RR message; and

receiving a Response message thereby closing the session.

23. The method of claim 22, wherein the act of avoiding aborting the session comprises:

waiting to send the RR message; and

sending the RR message after the session is closed.

24. The method of claim 22, wherein the act of avoiding aborting the session comprises dropping the RR message.

25. The method of claim 22, wherein the Request message comprises an RRLP Measure Position Request message.

means for determining, while the session is open, an RR message is ready to be sent to the mobile station;

means for avoiding aborting the session with the RR message; and

means for receiving a Response message thereby closing the session.

28. The network of claim 27, wherein the means for avoiding aborting the session comprises:

means for waiting to send the RR message; and
