Abstract

A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of: monitoring whether the mobile device has entered a new zone; starting a stabilization period when the mobile device enters a new zone; checking whether the mobile device enters a different zone during the stabilization period; if the mobile device enters a different zone during the stabilization period, restarting the stabilization period and performing the checking step; and if the mobile device does not enter a new zone during the stabilization period, determining whether the mobile device is in a new zone, reconnecting to the new zone if the mobile device is in the new zone, and otherwise performing no reconnection.

Claims

1. A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of:

monitoring whether the mobile device has entered a new zone from an original zone;

after the monitoring step has determined that the mobile device has entered a new zone, starting a stabilization period;

checking whether the mobile device enters a different zone during the stabilization period;

if the mobile device enters a different zone during the stabilization period, then restarting the stabilization period and performing said checking step; and

if the stabilization period ends and the mobile device has not entered a different zone, then determining whether the mobile device is in a new zone or said original zone, and if the mobile device is in said new zone, then performing reconnection of the point to point protocol link layer to the new zone, otherwise if the mobile device is in said original zone, performing no reconnection of the point to point protocol link layer to the new zone;

wherein the steps of the method are executed by the mobile device.

2. The method of claim 1, wherein said monitoring step looks for a change in a system identifier.

3. The method of claim 1, wherein said monitoring step looks for a change in a network identifier.

4. The method of claim 1, wherein said monitoring step looks for a change in a packet zone identifier.

5. The method of claim 1, wherein said starting step includes setting a stabilization timer.

6. The method of claim 5, wherein the duration of said stabilization timer is less than one minute.

7. The method of claim 5, wherein the duration of said stabilization timer is more than one minute.

8. A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of:

monitoring whether the mobile device has entered a new zone from an original zone;

after said monitoring step has determined that the mobile device has entered a new zone, initializing a max return counter;

starting a stabilization period;

checking whether the mobile device enters a different zone during the stabilization period;

after said checking step has determined that the mobile device enters a different zone, testing whether the mobile device is in said original zone and, if said mobile device is in said original zone, incrementing the max return counter and determining whether the max return counter has reached a threshold level and if said max return counter has reached a threshold level, performing reconnection of the point to point protocol link layer to said original zone;

if the mobile device enters a different zone during the stabilization period, then restarting the stabilization period and performing said checking step; and

if the stabilization period ends and the mobile device has not entered a different zone, then determining whether the mobile device is in a new zone or said original zone, and if the mobile device is in said new zone, performing reconnection of the point to point protocol link layer to the new zone, and otherwise if the mobile device is in said original zone, performing no reconnection of the point to point protocol link.

9. The method of claim 8, wherein said monitoring step looks for a change in a network identifier.

10. The method of claim 8, wherein said monitoring step looks for a change in a network identifier.

11. The method of claim 8, wherein said monitoring step looks for a change in a packet zone identifier.

12. The method of claim 8, wherein said starting step includes setting a stabilization timer.

13. The method of claim 12, wherein the duration of said stabilization timer is less than one minute.

14. The method of claim 12, wherein the duration of said stabilization timer is more than one minute.

15. The method of claim 8, wherein said method further comprises the steps of:

initializing and starting a countdown timer after said monitoring steps finds the mobile device has entered a new zone;

if said mobile device is in said original zone after said testing step, determining whether said countdown timer has expired, and if said countdown timer has expired, cancelling the stabilization period and performing a reconnection to said original zone.

16. The method of claim 15, further comprising the steps of:

determining whether said countdown timer has expired if said checking step finds said mobile device is not in said different zone,

if said countdown timer has expired, checking whether said mobile device is in said original zone, and if said mobile device is in said original zone, then cancelling said stabilization period and performing reconnection of the point to point protocol link layer.

17. A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of:

monitoring whether the mobile device has entered a new zone from an original zone;

after said monitoring step has determined that the mobile device has entered a new zone, initializing and starting a countdown timer;

starting a stabilization period;

checking whether the mobile device enters a different zone during the stabilization period;

after said checking step has determined that the mobile device enters a different zone, testing whether the mobile device is in said original zone and if said mobile device is in said original zone, determining whether said countdown timer has expired, and if said countdown timer has expired performing reconnection of the point to point protocol link layer in said original zone;

if the mobile device enters a different zone during the stabilization period, restarting the stabilization period and performing said checking step; and

if the stabilization period ends and the mobile device has not entered a different zone, determining whether the mobile device is in a new zone or said original zone, and if the mobile device is in said new zone, performing reconnection of the point to point protocol link layer to the new zone, and otherwise if the mobile device is in said original zone, performing no reconnection of the point to point protocol link layer.

18. The method of claim 17, further comprising the steps of:

determining whether said countdown timer has expired if said checking step finds said mobile device is not in said different zone,

if said countdown timer has expired, checking whether said mobile device is in said original zone, and if said mobile device is in said original zone, cancelling said stabilization period and performing reconnection of the point to point protocol link layer.

19. The method of claim 17, wherein said monitoring step looks for a change in a network identifier.

20. The method of claim 17, wherein said monitoring step looks for a change in a network identifier.

21. The method of claim 17, wherein said monitoring step looks for a change in a packet zone identifier.

22. The method of claim 17, wherein said starting step includes setting a stabilization timer.

23. The method of claim 22, wherein the duration of said stabilization timer is less than one minute.

24. The method of claim 22, wherein the duration of said stabilization timer is more than one minute.
