International ClassesH04B 001/06H04J 003/16 AbstractTIA IS-136 specifies the assignment to mobile stations of a unique international mobile station identification (IMSI) in addition to a mobile identification number (MIN). The IMSI number is communicated from the mobile station to the network, and is processed by the network to provide for non-ambiguous subscriber identification. Accordingly, the IMSI number is transmitted by the mobile station during registration, and processed during authentication to insure accurate and unique subscriber identification. Once registered with an IMSI instead of a MIN, the network utilizes the IMSI during subsequent call handling to insure, for example, proper call delivery and handoff.Other References
