A mobile station is coupled to a first base station via a first wireless connection while in the zone of the first base station zone. Through the first base station and in conjunction with a PPP session manager, the PPP session manager establishes a first link of a PPP session to a remote server across a data network having mobile station handoff capability. When moving into the zone of a second base station and in conjunction with the PPP session manager, the PPP session manager creates a second link of the PPP session. The first and second links take different paths through the data network. The PPP session manager releases the first link while preserving the PPP session.
