Measurement configuration and reporting of CSG cells in connected mode

1. An apparatus comprising:

at least one processor; and

at least one computer readable memory storing a program of computer executable instructions;

in which the at least one processor is configured with the at least one computer readable memory and program of computer executable instructions to cause the apparatus to perform at least:

sending to a user equipment in at least one measurement configuration message a range indicator by which a private cell can be distinguished from a non-private cell, a first indicator that indicates whether or not to report private cells in a measurement report, and a second indicator that indicates an identity filtering condition for which private cells are to have their measurements reported; and

receiving from the user equipment a measurement report that comprises, when the first indicator indicates to report private cells, a measurement indication for at least one private cell that is in compliance with the identify filtering condition of the second indicator.

2. The apparatus of claim 1 , in which the apparatus comprises an access node of an E-UTRA network and in which the range indicator comprises a CSG-PCI-Range information element for the at least one private cell.

3. The apparatus of claim 2 , wherein the CSG-PCI-Range information element is sent in a same measurement configuration message with the first indicator and the second indicator.

4. The apparatus of claim 3 , wherein the same message comprises a measurement configuration message which is sent to the user equipment in response to receiving from the user equipment a request for the CSG-PCI-Range information element.

5. The apparatus of claim 4 , in which the measurement configuration message further comprises an indication whether a carrier frequency for the private cells whose measurements are to be reported according to the second indicator is a dedicated frequency.

6. The apparatus of claim 1 , in which the second indicator directs the user equipment to report measurements on private cells whose physical cell identifier PCI matches an entry in a locally stored list of allowed private cells.

7. The apparatus of claim 1 , in which the second indicator directs the user equipment to report measurements on private cells whose closed subscriber group identifier CSG-ID matches an entry in a locally stored list of allowed closed subscriber groups.

8. An apparatus comprising:

at least one processor; and

at least one computer readable memory storing a program of computer executable instructions;

in which the at least one processor is configured with the at least one computer readable memory and program of computer executable instructions to cause the apparatus to perform at least:

receiving from a network in at least one measurement configuration message a range indicator by which a private cell can be distinguished from a non-private cell, a first indicator that indicates whether or not to report private cells in a measurement report, and a second indicator that indicates an identity filtering condition for which private cells are to have their measurements reported;

using the second indicator to filter from a plurality of cells at least one first private cell to report and at least one second private cell not to report;

using the received range indicator to distinguish private cells from non-private cells; and

sending to the network a measurement report that comprises, in compliance with the first and second indicators, a measurement indication for the at least one first private cell, and no measurement indication for the at least one second private cell, when the first indicator indicates to report private cells.

9. The apparatus of claim 8 , in which the apparatus comprises a user equipment operating in an E-UTRA network, and in which the range indicator comprises a CSG-PCI-Range information element for the at least one private cell.

10. The apparatus of claim 9 , wherein the CSG-PCI-Range information element is received in a same measurement configuration message with the first indicator and the second indicator.

11. The apparatus of claim 10 , wherein the same message comprises a measurement configuration message which is received in response to the user equipment sending to the network a request for the CSG-PCI-Range information element.

12. The apparatus of claim 11 , in which the measurement configuration message further comprises an indication whether a carrier frequency for the private cells whose measurements are to be reported according to the second indicator is a dedicated frequency.

13. The apparatus of claim 8 , in which using the second indicator to identify the at least one cell to report comprises determining from the second indicator to report measurements on private cells whose physical cell identifier PCI matches an entry in a locally stored list of allowed private cells.

14. The apparatus of claim 8 in which using the second indicator to identify the at least one cell to report comprises determining from the second indicator to report measurements on private cells whose closed subscriber group identifier CSG-ID matches an entry in a locally stored list of allowed closed subscriber groups.

15. A non-transitory computer readable memory storing a program of computer readable instructions that when executed by at least one processor result in actions comprising:

receiving from a network in at least one measurement configuration message a range indicator by which a private cell can be distinguished from a non-private cell, a first indicator that indicates whether or not to report private cells in a measurement report, and a second indicator that indicates an identity filtering condition for which private cells are to have their measurements reported;

using the second indicator to filter from a plurality of cells at least one first private cell to report and at least one second private cell not to report;

using the received range indicator to distinguish private cells from non-private cells; and

sending to the network a measurement report that comprises, in accordance with the first and second indicators a measurement indication for the at least one first private cell, and no measurement indication for the at least one second private cell, when the first indicator indicates to report private cells.

16. The non-transitory computer readable memory of claim 15 , wherein the CSG-PCI-Range information element is received in a same message with the first indicator and the second indicator.

17. The non-transitory computer readable memory of claim 16 , wherein the same message comprises a measurement configuration message which is received in response to the user equipment sending to the network a request for the CSG-PCI-Range information element.

18. The non-transitory computer readable memory of claim 17 , in which the measurement configuration message further comprises an indication whether a carrier frequency for the private cells whose measurements are to be reported according to the second indicator is a dedicated frequency.

19. The non-transitory computer readable memory of claim 15 , wherein the range indicator, the first indicator and the second indicator are received in a measurement configuration message which is received in response to sending to the network a request for a CSG-PCI-Range information element; and in which the range indicator comprises the CSG-PCI-Range information element for the at least one private cell.

20. The non-transitory computer readable memory of claim 15 , in which using the second indicator to identify the at least one cell to report comprises determining from the second indicator to report measurements on private cells whose physical cell identifier PCI matches an entry in a locally stored list of allowed private cells, or whose closed subscriber group identifier CSG-ID matches an entry in a locally stored list of allowed closed subscriber groups.
