CDMA to GSM• SIM roaming using two separate

handsets when roaming in the GSM network is fully supported.

• Changing the SIM between phones while the ANSI-41 subscriber is in the home network may cause problem outside the scope of the IIF.

21

• All standard ANSI-41 authentication– Global challenge– Unique challenge (automatic or manual)– Shared secret data (SSD) sharing with ANSI-41 VLR– SSD update (automatic or manual)– CallHistoryCount update (automatic or manual)

• Voice privacy and signaling message encryption• Authentication key management

– Now RoamFree-specific key management system (RKMS) application is integrated with SAC application on Digital AlphaServer platform

– Carrier bulkloads {IMSI, A-Key} pairs from SIM vendor datafile– A-Keys are securely stored in encrypted form; SAC application uses only SSD

generated by RKMS application

GSM Association Press Release

INTERSTANDARD ROAMING GOES GLOBAL AS FIRST GSM-CDMA AGREEMENT KICKS OFF IN KOREA

World Cup visitors can use GSM service on CDMA handsets

15 January 2002 - LONDON, UK: The GSM Association, the world's leading wireless industry organisation, has announced the first successful GSM-CDMA inter-standard international roaming. The wireless technology breakthrough was achieved with an unprecedented cooperation between the GSM Association's Global Roaming Forum (GGRF), Korean CDMA operator Korea Telecom Freetel (KTF) and Bouygues Telecom, which operates the French GSM 1800 network.

The GGRF is driving inter-standard roaming, and the commercial launch enables KTF to provide roaming services to visiting GSM subscribers from networks with a roaming agreement in place with KTF. The first of these is Bouygues Telecom. The partnership is pertinent and timely as the French operator's home country will be defending the FIFA World Cup in this year's football tournament, hosted in Korea and Japan in the coming months.

KTF has developed intelligent handsets that accept the visiting GSM SIM card, so all personal information is still available to the roaming client, who also retains his GSM number. With the World Cup kicking off in June, KTF anticipates a potential 100,000 GSM roaming clients during the year.
