At the recent 3G World
Congress in Hong Kong, Qualcomm Inc. along with SchlumbergerSema,
and Samsung Telecommunications America Inc. demonstrated what is
referred to as a removable user identity module (R-UIM) solution
that enables users to roam across CDMA and GSM networks — bringing
us a little closer to that day when we can roam anywhere in the
world and stay connected.
The demonstration was a true collaborative effort: Qualcomm CDMA
technologies (QCT) Mobile Station Modem (MSM) was integrated with a
R-UIM interface and R-UIM Simera Airflex system developed by
SchlumbergerSema in a Samsung handset. By storing a subscriber’s
identity on a single removable card, the companies proved that a
user could exchange handsets to roam across different network
frequencies, while using the same card to maintain all their
personal information, including network setting, privileges,
preferences, and phone books.
Vice president of product management for Qualcomm CDMA
technologies Luis Pineda said, "These solutions can now be
adopted to roll out R-UIM-enabled handsets using our MSM products
and SchlumbergerSema smart cards as CDMA network operators begin to
specify this feature for their wireless devices."
The Samsung R-UIM-enabled phone, using QCT‘s MSM3100 IS-95A/B
integrated circuit and system software with integrated R-UIM
interface to operate with the Simera Airflex R-UIM card, was built
for the Japanese and Korean markets where the demand for R-UIM
capabilities is growing, the companies said in a statement.
"The system solutions from QCT and SchlumbergerSema [were]
designed to meet the market requirements in China and Korea,
allowing us to achieve significant time to market advantages to roll
out a validated R-UIM solution," said Kim HyunJoo, R&D
manager of mobile communications for Samsung.
SchlumbergerSema is currently developing a R-UIM for integration
in the MSM5500 and subsequent MSM6xxx CDMA2000 1X integrated
circuits. In addition, the company has delivered test cards to many
manufacturers and operators in China, Japan, Korea, and the United
States for handset development and field trials.
