Method for routing mobile phone signaling messages between different collaborating networks (20,30) including an STP (25,35) and at least two home networks (10,40) including an STP (16,36). A collaborating ITP (29,39) is connected to a collaborating STP (25,35), a home ITP (17,47) is connected to a home STP (16,46), and a central ITP (51) is connected to each ITP via a wide area network (6) which is not a PSTN. A visited country IMSI identifies a mobile subscriber as a subscriber to a collaborating network. A visited IMSI is associated with a home network in the central ITP. A signaling message, including the visited IMSI, is sent from a collaborating STP to the collaborating ITP, and is forwarded to the central ITP. The message is forwarded from the central ITP to a home ITP with which the visited IMSI is associated, and sent to the corresponding home STP. |
