1. A code division multiple access (CDMA) mobile station (MS), comprising:
- a radio circuit configured to communicate with a CDMA radio access network (RAN) using CDMA protocol; and
a subscriber circuit configured to communicate with a GSM subscriber identity module (SIM) to permit the MS to authenticate itself with a GSM core infrastructure, whereby use of the CDMA RAN with the GSM core infrastructure is facilitated.

Abstract
A CDMA mobile station (MS) can be engaged with a GSM subscriber identity module (SIM) to authenticate the MS with a GSM core infrastructure using a CDMA radio access network (RAN) through a hybrid CDMA/GSM message switching center (MSC), such that use of the CDMA RAN with the existing GSM core advantageously is facilitated.

16. A method for facilitating the use of a CDMA RAN with a GSM core infrastructure, comprising:
-
engaging a SIM with a CDMA MS;
transmitting at least one IMSI stored on the SIM to an MSC using a CDMA RAN;
using the IMSI, authenticating the SIM with a GSM core infrastructure; and
based on the authenticating act, registering the MS with SIM with the MSC. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A system for facilitating the use of a CDMA RAN with a GSM core infrastructure, comprising:
-
an MSC communicating with the CDMA RAN using CDMA protocol, the MSC also communicating with the GSM core infrastructure using GSM protocol;
at least one MS communicating with the CDMA RAN and having a registration in the GSM core infrastructure; and
at least one SIM detachably engageable with the MS for authenticating the MS with the GSM core infrastructure. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
