Abstract
A method of operating a communication system is disclosed. A first communication session between a first base station and a mobile station is established. A service session between a first access network and the mobile station is established. When the mobile station moves to the service area of a new base station, a second communication session between a second base station and the mobile station is established. A distance between the first base station and the second base station is determined. If the distance exceeds a criteria, the service session is handed off a second access network. The criteria, which must be greater than zero, corresponds to the number of base station service areas separating the first base station and the second base station.
