Systems and methods for assigning a mobility parameter to a wireless device operating in connected mode

1. A method for assigning a mobility parameter to a wireless device, the method comprising:

collecting, at an access node, one or more measurement reports from a wireless device;

calculating a pathloss change for the wireless device based on the collected measurement reports;

instructing the wireless device to report surplus transmit power at the access node when the calculated pathloss change exceeds a threshold;

correlating the reported surplus transmit power and calculated pathloss change to preset reference values corresponding to location environments;

classifying a location environment of the wireless device based on the correlation;

assigning a mobility parameter for the wireless device based on the classified location environment; and

enabling position estimation of the wireless device using one or more signals communicated between one or more access nodes and the wireless device, the enabling being based on the assigned mobility parameter.

2. The method of claim 1 , wherein the measurement report includes data of one or more of RSSI, RSRP, and RSRQ.

3. The method of claim 2 , wherein the measurement data is used to calculate the location environment of the wireless device in a radio range of the access node.

4. The method of claim 1 , wherein the surplus transmit power report includes one or more of an uplink transmit power state, Power Headroom Report (PHR), and Extended Power Headroom Report (ePHR).

5. The method of claim 4 , wherein the pathloss is calculated at the wireless device from a change between a transmit power value of the access node and the surplus transmit power report of the wireless device.

6. The method of claim 1 , wherein the location environments are one of outdoor, dense/urban, and indoor environments.

7. The method of claim 6 , wherein the correlating further comprises comparing the reported surplus transmit power of the wireless device to reference value ranges for surplus transmit power stored at a look-up table at the access node.

8. The method of claim 1 , wherein the assigned mobility parameter corresponds to an indoor environment.

9. The method of claim 8 :

wherein the using one or more signals communicated between one or more access nodes and the wireless device comprises implementing Enhanced Cell ID (ECID) and/or Observed Time Difference of Arrival (OTDoA) techniques to determine a position of the wireless device in a radio range of the access node.

10. A system for assigning a mobility parameter to a wireless device, the system comprising:

a controller configured to:

collect, at an access node, one or more measurement reports from a wireless device;

calculate, at a processing node, a pathloss change for the wireless device based on the collected measurement reports;

instruct the wireless device to report surplus transmit power at the access node when the calculated pathloss change exceeds a threshold;

correlate the reported surplus transmit power and the calculated pathloss change to preset reference values corresponding to location environments;

classify a location environment of the wireless device based on the correlation;

assign a mobility parameter for the wireless device based on the classified location environment; and

enable position estimation of the wireless device using one or more signals communicated between one or more access nodes and the wireless device, the enabling being based on the assigned mobility parameter.

11. The system of claim 10 , wherein the measurement report includes measurement data associated with ranging satellite signals received at the wireless device.

12. The system of claim 11 , wherein the measurement data includes one or more of code phase, Doppler, RSSI, RSRP, and RSRQ.

13. The system of claim 12 , wherein the measurement data is used to calculate the location environment of the wireless device in a radio range of the access node.

14. The system of claim 10 , wherein the surplus transmit power report includes one or more of an uplink transmit power state, Power Headroom Report (PHR), and Extended Power Headroom Report (ePHR).

15. The system of claim 14 , wherein the pathloss change is calculated at the wireless device from a change between a transmit power value of the access node and the surplus transmit power report of the wireless device.

16. The system of claim 10 , wherein the location environments are one of outdoor, dense/urban, and indoor environments.

17. The system of claim 16 , wherein the controller is further configured to compare the reported surplus transmit power of the wireless device to reference value ranges for surplus transmit power stored at a look-up table at the access node.

18. The system of claim 10 , wherein

wherein the using one or more signals communicated between one or more access nodes and the wireless device comprises implementing Enhanced Cell ID (ECID) and/or Observed Time Difference of Arrival (OTDoA) techniques to determine a position of the wireless device in a radio range of the access node.

19. A method for classifying a wireless device operating in a radio range of an access node, the method comprising:

instructing a wireless device to report surplus transmit power at an access node when a pathloss change of the wireless device exceeds a threshold;

correlating the reported surplus transmit power to preset location value ranges in response to the pathloss change exceeding the threshold;

based on the correlation, classifying a location environment of the wireless device in the radio range of the access node as indoor or outdoor; and

enabling position estimation of the wireless device using one or more signals communicated between one or more access nodes and the wireless device, the enabling being based on the classified location environment.
