Abstract

Exemplary methods and systems may help to adjust switch-level page settings based on both the performance of the wireless communication device (WCD) that is being paged, and the sector in which the WCD is likely to be located. An exemplary method involves a switch determining that a WCD should be paged and responsive to determining that the WCD should be paged: (a) determining a coverage-area performance indicator for a last-known coverage area of the WCD; (b) determining a WCD performance indicator for the WCD; (c) using both (i) the WCD performance indicator and (ii) the coverage-area performance indicator as a basis for adjusting at least one paging-scheme setting affecting attempts to page the WCD; and (d) paging the WCD according to the at least one adjusted paging-scheme setting.

Claims

1. A method comprising:

at a switch in a radio access network, determining that a wireless communication device (WCD) should be paged; and

responsive to determining that the WCD should be paged, the switch;

determining a coverage-area performance indicator for a last-known coverage area of the WCD;

determining a WCD performance indicator for the WCD, wherein the WCD performance indicator comprises a percentage of calls involving the WCD that have been dropped by the WCD;

using both (i) the WCD performance indicator and (ii) the coverage-area performance indicator, as a basis for adjusting at least one paging-scheme setting of the switch affecting attempts to page the WCD, wherein using both the WCD performance indicator and the coverage-area performance indicator as a basis for adjusting at least one paging-scheme setting comprises;

(a) determining an overall performance indicator based at least in part on (i) the WCD performance indicator and (ii) the coverage-area performance indicator, and (b) using the overall performance indicator as a basis for adjusting at least one paging-scheme setting affecting attempts to page the WCD; and

paging the WCD according to the at least one adjusted paging-scheme setting.

2. The method of claim 1, further comprising, determining the last-known coverage area of the WCD.

3. The method of claim 2, wherein the last-known coverage area of the WCD is a coverage area in which a last call of the WCD ended.

4. The method of claim 2, wherein the last-known coverage area of the WCD is a coverage area in which the WCD last registered with the radio access network.

5. The method of claim 1, wherein the coverage-area performance indicator comprises a measure of dropped calls for the last-known coverage area of the WCD.

6. The method of claim 5, wherein the measure of dropped calls comprises a percentage of calls in the last-known coverage area that are dropped.

7. The method of claim 5, wherein the measure of dropped calls comprises an average number of dropped calls in the last-known coverage area per unit of time.

8. The method of claim 1, wherein adjusting at least one paging-scheme setting affecting attempts to page the WCD comprises adjusting at least one setting for zone-based paging.

9. The method of claim 1, wherein adjusting at least one paging-scheme setting affecting attempts to page the WCD comprises adjusting a maximum attempt parameter.

10. The method of claim 1, wherein adjusting at least one paging-scheme setting affecting attempts to page the WCD comprises adjusting at least one setting for intersystem paging.

11. The method of claim 1, wherein adjusting at least one paging-scheme setting affecting attempts to page the WCD comprises setting a duration of a page-attempt timer.

12. The method of claim 1, wherein determining the overall performance indicator comprises:

determining an average of the (i) the WCD performance indicator and (ii) the coverage-area performance indicator; and

using the average as a basis for determining the overall performance indicator.

13. The method of claim 1, wherein determining the overall performance indicator comprises:

determining a sum of the (i) the WCD performance indicator and (ii) the coverage-area performance indicator; and

using the sum as a basis for determining the overall performance indicator.

14. A method comprising:

at a switch in a radio access network, determining that a wireless communication device (WCD) should be paged;

determining a WCD performance indicator for the WCD, wherein the WCD performance indicator comprises a percentage of calls involving the WCD that have been dropped by the WCD;

determining a coverage-area performance indicator for a last-known coverage area of the WCD;

using both (i) the WCD performance indicator and (ii) the coverage-area performance indicator as a basis for adjusting at least one paging-scheme setting of the switch affecting attempts to page the WCD, wherein using both the WCD performance indicator and the coverage-area performance indicator as a basis for adjusting at least one paging-scheme setting comprises;

(a) determining an overall performance indicator based at least in part on (i) the WCD performance indicator and (ii) the coverage-area performance indicator, and (b) using the overall performance indicator as a basis for adjusting at least one paging-scheme setting affecting attempts to page the WCD; and

paging the WCD according to the at least one adjusted paging-scheme setting.

15. The method of claim 14, further comprising:

determining an overall performance indicator based at least in part on (i) the WCD performance indicator and (ii) the coverage-area performance indicator;

wherein using both (i) the WCD performance indicator and (ii) the coverage-area performance indicator as bases for adjusting the at least one paging-scheme setting comprises using the overall performance indicator as a basis for adjusting at least one paging-scheme setting affecting attempts to page the WCD.

16. A system comprising:

a non-transitory computer readable medium; and

program instructions stored on the non-transitory computer readable medium and executable by at least one processor to;

determine that a wireless communication device (WCD) should be paged;

determine a WCD performance indicator for the WCD, wherein the WCD performance indicator comprises a percentage of calls involving the WCD that have been dropped by the WCD;

determine a coverage-area performance indicator for a last-known coverage area of the WCD;

use both (i) the WCD performance indicator and (ii) the coverage-area performance indicator as a basis to adjust at least one paging-scheme setting of the switch affecting attempts to page the WCD, wherein the use of both the WCD performance indicator and the coverage-area performance indicator as a basis to adjust at least one paging-scheme setting comprises;

(a) a determination of an overall performance indicator based at least in part on (i) the WCD performance indicator and (ii) the coverage-area performance indicator, and (b) use of the overall performance indicator as a basis for adjusting at least one paging-scheme setting affecting attempts to page the WCD; and

page the WCD according to the at least one adjusted paging-scheme setting.

17. A method comprising:

at a switch in a radio access network, determining that a wireless communication device (WCD) should be paged; and

responsive to determining that the WCD should be paged, the switch;

determining a coverage-area performance indicator for a last-known coverage area of the WCD;

determining a WCD performance indicator for the WCD, wherein the WCD performance indicator comprises an average number of dropped calls by the WCD per unit of time;

using both (i) the WCD performance indicator and (ii) the coverage-area performance indicator, as a basis for adjusting at least one paging-scheme setting of the switch affecting attempts to page the WCD; and

paging the WCD according to the at least one adjusted paging-scheme setting;

wherein using both the WCD performance indicator and the coverage-area performance indicator as a basis for adjusting at least one paging-scheme setting comprises;

(a) determining an overall performance indicator based at least in part on (i) the WCD performance indicator and (ii) the coverage-area performance indicator, and (b) using the overall performance indicator as a basis for adjusting at least one paging-scheme setting affecting attempts to page the WCD.
