摘要
A method for handing off calls between differing radio telecommunication networks recognizes (302) a desire for an inter- network hand-off. When a Subscriber Unit (120) (SU) identifies (304) a new network, a hand-off with the new network can be requested (320). When the SU (120) does not identify (304) a new network, the old network requests (314) location information relevant to an inter-network hand- off from a Location Inter-Working Server (200) (LIWS). The LIWS (200) provides information about other networks which provide service to the SU location and, when another network provides service to the SU location, a hand-off with the other network can be requested (320).
