Abstract

A method and apparatus are presented for generating unique MSIDs for access terminals (AT) that do not present an MSID to the access network controller (ANC). The electronic serial number (ESN) of the AT is first converted to an ASCII character string representing the unsigned decimal equivalent of the 32 bit ESN. The ASCII string is padded with leading “0” (zeros), if necessary, to create a 10 character string. The ANC generates a 5 character string unique to all 1xEVDO networks then concatenates the two strings to create a unique 15 character string. The created 15 character string is then presented to the PDSN to establish a network session.
