Abstract:
In one aspect of the instant invention, a method is provided for controlling a communications system. The method comprises storing a 15-digit universal identifier in a mobile device in two locations ordinarily used to store a 15-digit MIN-based _IMSI and a 15-digit true IMSI. The universal identifier is comprised of a 10-digit Mobile Identification Number (MIN) and a 5-digit Home Network Identifier (HNI), which is comprised of a 3-digit Mobile Country Code (MCC) and a 2-digit Mobile Network Code (MNC). Generally, the communications system uses the universal identifier to control international 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.
Abstract:
A method is provided for controllably migrating a wireless network from MIN based operation to IMSI based operation. The method comprises implementing changes that affect inter-network operations during a first phase of the migration. Remaining changes, including changes that affect intra-network operations are implemented during a second phase of the migration.

Abstract:
In an embodiment of the method of handling mobile station identifiers, at least one network element (36, 30) that used entire mobile station identifiers in performing packet data session handling functions is programmed to use less than the entire mobile station identifiers.
