摘要
In one aspect of the instant invention, a method is provided for controlling roaming in a communications system. The method comprises storing a 15-digit MIN-based-IMSI in the mobile device. The 15-digit MIN-based-IMSI is comprised of a 10-digit Mobile Identification Number (MIN) and a 15- digit Home Network Identifier (HNI). Generally, the communications system uses the 15-digit MIN- based-IMSI to control roaming. However, the mobile device transmits only the 10-digit MIN in response to the mobile device being within a home network. To form the 15-digit universal identifier, the home network appends its HNI to the received MIN. When the mobile device is outside of its home network, the mobile device transmits the entire 15-digit universal identifier.
