ok, section 3.3 is removed.

Rewording:

When SNAPs are used, the operating system can notify applications when a preferred IAP, leading to the same destination, becomes available (for example, when a user comes within range of his home WLAN access point), or when the currently used IAP is no longer available. If so, applications have to reconnect via another IAP (for example, when a user goes out of range of his home WLAN and must move to the cellular network).

n/a since section is removed.
