Abstract
While a mobile node is engaged in a communication session via a first air interface channel, the user of the mobile node requests a vertical handoff. In response to the user's handoff request, the mobile node goes into a dormant mode to release the first air interface channel. The mobile node then acquires a second air interface channel, which may have a higher data rate than the first air interface channel, and continues the communication session via the second air interface channel. The mobile node may also determine that a vertical handoff may be available, e.g., by checking a preferred roaming list (PRL), and then indicate to the user that a vertical handoff may be available.
