The present invention relates to a method of authenticating with an authentication center (20) a mobile station (16) handing-off from an anchor exchange (12A) to a serving exchange (12S). The method sends authenticating parameters for the mobile station from the authentication center to the anchor exchange. The mobile station is asked to authenticate with the anchor exchange. While the authenticating takes place, the mobile station hands-off from the anchor exchange to the serving exchange. The authenticating parameters are forwarded from the anchor exchange to the serving exchange, and the mobile station is asked to authenticate with the serving exchange. The serving exchange receives the authenticating results from the mobile station, and sends them to the authentication center.
