Abstract: A method for connecting to an access point base station is presented in the application. Current location information of the mobile access terminal may be determined. The current location information may be determined using positioning location circuitry of the mobile access terminal to determine the current location information. Alternatively, the current location information may be determined by receiving the current location information from an external source. The mobile access terminal may determine the current location based on signals from macro base stations or other base stations, e.g., using triangulation. If the current location information indicates, the mobile access terminal may then connect to an access point base station.
