Abstract
A method and apparatus for resetting a maximum tunnel watermark, the method starting a reset timer for a maximum tunnel count at a mobile device; on expiration of the reset timer, checking whether a current value for the maximum tunnel count is less than a maximum value for the maximum tunnel count, and if yes, setting the current value of the maximum tunnel count to the maximum value of the maximum tunnel count.
Claims18
A method comprising:
- starting a reset timer for a maximum tunnel count at a mobile device the reset timer being associated with a location area of the mobile device;
- on expiration of the reset timer, if a current location area of the mobile device is associated with the expired reset timer, checking whether a current value for the maximum tunnel count is less than a maximum value for the maximum tunnel count permitted by a network, and
- if yes, setting the current value of the maximum tunnel count to the maximum value of the maximum tunnel count permitted by the network;
- and
- if the current location area of the mobile device is not associated with the expired reset timer, flagging an entry for the location area associated with the expired reset timer.
