Methods and apparatus for reducing roaming latency in a mobile node
First Claim
1. A method of triggering roaming in a network device, comprising:
- detecting a speed of the network device;
ascertaining one or more trigger values corresponding to one or more trigger events at the speed of the network device;
maintaining one or more trigger counters associated with the one or more trigger events; and
triggering roaming when one of the trigger counters associated with one of the trigger events is equal to or exceeds one of the trigger values corresponding to the one of the trigger events at the speed of the network device.

Abstract
Methods and apparatus for triggering roaming in a mobile network device are disclosed. A speed of the network device is detected. One or more maximum/minimum trigger values corresponding to one or more trigger events are ascertained at the speed of the network device. One or more trigger counters associated with the one or more trigger events are maintained. Roaming of the network device is triggered when one of the trigger counters associated with one of the trigger events is equal to or exceeds (or is less than or equal to) one of the trigger values corresponding to the trigger event at the speed of the network device.
