Optimized data reconnect
View Patent ↗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.
1. A method of maintaining data connectivity of a mobile station in a network, comprising:
establishing a data link between the mobile station and a first zone;
entering, by the mobile station, a second zone while retaining the data link with the first zone;
upon detecting that the mobile station has entered the second zone, initiating, by the mobile station, a timer-based preset period of time during which connecting of the data link to the second zone will be postponed;
postponing connecting the data link to the second zone until after the preset period of time ends; and
when the preset period of time ends if the mobile station is still in the second zone, then connecting the data link to the second zone;
detecting that the mobile station has entered a third zone from the second zone during the preset period of time;
in response to detecting that the mobile station has entered the third zone, re-initiating the timer-based preset period of time;
after the preset period of time ends, determining if the mobile station is in the third zone; and
if the mobile station is in the third zone after the preset period of time ends, then connecting the data link to the third zone.
2. The method of claim 1 , wherein if the mobile station is in the first zone after the preset period of time ends, then maintaining the data link between the mobile station and the first zone.
3. The method of claim 1 , wherein if the mobile station is in the first zone after the preset period of time ends, then reconnecting the data link between the mobile station and the first zone.
4. The method of claim 1 , wherein the data link is a point to point protocol link.
5. The method of claim 1 , wherein a change in a system identifier is detected to indicate that the mobile station has entered the second zone from the first zone.
6. The method of claim 1 , wherein a change in a network identifier is detected to indicate that the mobile station has entered the second zone from the first zone.
7. The method of claim 1 , wherein a change in a packet identifier is detected to indicate that the mobile station has entered the second zone from the first zone.
8. A mobile station that includes a processor and a non-transitory computer readable storage medium that stores software instructions for maintaining data connectivity in a network, the software instructions being executable by the processor to:
establish a data link between the mobile station and a first zone;
detect that the mobile station has entered a second zone while retaining the data link with the first zone;
upon detecting that the mobile station has entered the second zone, initiate a timer-based preset period of time during which connecting of the data link to the second zone will be postponed;
postpone connecting the data link to the second zone until after the preset period of time ends; and
when the preset period of time ends, if the mobile station is still in the second zone, then connect the data link to the second zone;
detect that the mobile station has entered a third zone from the second zone during the preset period of time;
in response to detecting that the mobile station has entered the third zone, restart the timer-based preset period of time;
after the preset period of time ends, determine if the mobile station is in the third zone; and
if the mobile station is in the third zone after the preset period of time ends, then connect the data link to the third zone.
9. The mobile station of claim 8 , wherein if the mobile station is in the first zone after the preset period of time ends, then the software instructions being configured to maintain the data link between the mobile station and the first zone.
10. The mobile station of claim 8 , wherein if the mobile station is in the first zone after the preset period of time ends, then the software instructions being configured to reconnect the data link between the mobile station and the first zone.
11. The mobile station of claim 8 , wherein the data link is a point to point protocol link.
12. The mobile station of claim 8 , wherein a change in a system identifier is detected to indicate that the mobile station has entered the second zone from the first zone.
13. The mobile station of claim 8 , wherein a change in a network identifier is detected to indicate that the mobile station has entered the second zone from the first zone.
14. The mobile station of claim 8 , wherein a change in a packet identifier is detected to indicate that the mobile station has entered the second zone from the first zone.
