Abstract

Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.

Claims

1. A method for reporting access point measurements to restricted access points, comprising:

performing one or more measurements of a signal from a first restricted access point;

generating a minimization of drive tests (MDT) log comprising the one or more measurements along with a related cell identifier; and

reporting the MDT log to an MDT service.

2. The method of claim 1, wherein the generating the MDT log is based at least in part on a timer, a location, a serving cell channel quality, receiving paging signals, detecting the first restricted access point, or determining a logging storage as related to a capacity.

3. The method of claim 1, wherein the MDT service provides at least one of the one or more measurements from the MDT log to a second restricted access point based at least in part on determining a cell identifier in the at least one of the one or more measurements.

4. The method of claim 3, wherein the MDT provides the at least one of the one or more measurements based at least in part on a request from the second restricted access point for access point measurements.

5. The method of claim 4, wherein the request is received from a management server for the second restricted access point.

6. The method of claim 3, wherein the second restricted access point utilizes the one or more measurements in performing an EIM.

7. The method of claim 6, wherein the second restricted access point further receives one or more additional access point measurements from one or more devices that are a member of a closed subscriber group, and wherein the second restricted access point further utilizes the one or more additional access point measurements in performing the EIM.

8. An apparatus for reporting access point measurements to restricted access points, comprising:

at least one processor configured to;

perform one or more measurements of a signal from a first restricted access point;

generate a minimization of drive tests (MDT) log comprising the one or more measurements along with a related cell identifier; and

report the MDT log to an MDT service; and

a memory coupled to the at least one processor.

9. The apparatus of claim 8, wherein the at least one processor generates the MDT log based at least in part on a timer, a location, a serving cell channel quality, receiving paging signals, detecting the first restricted access point, or determining a logging storage as related to a capacity.

10. The apparatus of claim 8, wherein the MDT service provides at least one of the one or more measurements from the MDT log to a second restricted access point based at least in part on determining a cell identifier in the at least one of the one or more measurements.

11. The apparatus of claim 10, wherein the MDT provides the at least one of the one or more measurements based at least in part on a request from the second restricted access point for access point measurements.

12. The apparatus of claim 11, wherein the request is received from a management server for the second restricted access point.

13. The apparatus of claim 10, wherein the second restricted access point utilizes the one or more measurements in performing an EIM.

14. The apparatus of claim 13, wherein the second restricted access point further receives one or more additional access point measurements from one or more devices that are a member of a closed subscriber group, and wherein the second restricted access point further utilizes the one or more additional access point measurements in performing the EIM.

15. A computer program product for reporting access point measurements to restricted access points, comprising:

a computer-readable medium, comprising;

code for causing at least one computer to perform one or more measurements of a signal from a first restricted access point;

code for causing the at least one computer to generate a minimization of drive tests (MDT) log comprising the one or more measurements along with a related cell identifier; and

code for causing the at least one computer to report the MDT log to an MDT service.

16. The computer program product of claim 15, wherein the code for causing the at least one computer to generate generates the MDT log based at least in part on a timer, a location, a serving cell channel quality, receiving paging signals, detecting the first restricted access point, or determining a logging storage as related to a capacity.

17. The computer program product of claim 15, wherein the MDT service provides at least one of the one or more measurements from the MDT log to a second restricted access point based at least in part on determining a cell identifier in the at least one of the one or more measurements.

18. The computer program product of claim 17, wherein the MDT provides the at least one of the one or more measurements based at least in part on a request from the second restricted access point for access point measurements.

19. The computer program product of claim 17, wherein the second restricted access point utilizes the one or more measurements in performing an EIM.

20. The computer program product of claim 19, wherein the second restricted access point further receives one or more additional access point measurements from one or more devices that are a member of a closed subscriber group, and wherein the second restricted access point further utilizes the one or more additional access point measurements in performing the EIM.
