Abstract
Methods and apparatus for selecting a system for communication with a personal station, such as a cellular telephone or a PCS station, in a roaming area. The personal station transmits a system access message to a default system. When the default system that receives the system access message is a visited system in the roaming area and the personal station is not registered with the visited system, the visited system registers the presence of the personal station in the roaming area with a home system for the personal station. The home system sends a response including a selection indication to the personal station through the visited system. The selection indication contains selection information for controlling selection of a system for communication with the personal station in the roaming area. The personal station selects a system for communication in the roaming area in accordance with the selection information.
