Schlumberger Test & Transactions, a business segment of Schlumberger Limited announced mobile phone operator Korea Telecom Freetel?s subscribers are the first in the world to benefit from international roaming between Code Division Multiple Access and Global System for Mobile Communication networks via Simera Airflex, a unique removable user identity module (R-UIM ) smart card developed by Schlumberger. This is the world’s first commercial application for the new R-UIM card. Delivery of the new service to KTF subscribers is expected to be in time for use by Korean visitors to the Sydney Olympic games.
Simera Airflex is the first card to implement the R-UIM standard for CDMA phones, which allows CDMA subscribers to place the card into the subscriber identity module (SIM) slot of a GSM phone when travelling and obtain GSM network coverage. This gives Korea Telecom Freetel?s customers international roaming in 86 countries, including 45 states in the USA, covered by GSM networks.
The R-UIM specification provides subscribers with an internationally-compatible and removable identity module for both the CDMA and GSM networks as well as enables GSM network coverage throughout the world. The R-UIM identity module provides a flexible platform for the development and deployment of value-added services (VAS) for KTF?s subscribers. Value added services can now be developed with the existing GSM SIM Toolkit (STK). Thanks to compatibility with the Java Card standard, it is also possible to re-load and change applets on the Simera Airflex in the field.
This approach greatly simplifies VAS development compared with producing dedicated application firmware for the embedded processor inside the phone. Moreover, the new card opens up a migration path for KTF to the use of identity modules in the third generation (3G) evolution for CDMA terminals, providing the benefits of smart card-based security for mobile commerce.
KTF’s CDMA subscribers travelling to countries within the global GSM footprint now simply take their R-UIM module card and plug it into a GSM handset to gain instant access to the new network. KTF plans to make available rental handsets at the company’s lounge in Kimpo International Airport.
“Simera Airflex cards give us a powerful platform for evolving our mobile communications brand”, said Pyo Hyun Myung, vice president of Korea Telecom Freetel. “Right now, they help us to introduce truly international roaming services. In the future, they will give us an additional flexible route for delivering value-added services, which can be personalized to suit individual subscribers.”
“The smart card-based identity module is a catalyst for the evolution of mobile phones, allowing services to be provided both ergonomically and with very high levels of security,” said Jean Claude Deturche, vice president of marketing for Mobile Communications & Public Telephony, Asia Pacific. ?The R-UIM offers great potential and we have been delighted to work with such a forward looking operator as KTF to pioneer its role in CDMA networks. We expect KTF’s new service to be an influential example for CDMA operators worldwide?.
The Simera Airflex card was developed by Schlumberger at its regional Asia-Pacific Technical Center in Hong Kong. They are fabricated and personalized at the Schlumberger manufacturing plant in Hong Kong.
