SAN DIEGO--(BUSINESS WIRE)--Oct. 7, 2003

3G Radio and Core Network Solutions Help Drive 3G Adoption

Continuous Computing Corporation (CCPU), the leading provider of communications software solutions, announced today that it has begun shipping Trillium(R) network protocol software solutions complying with the Third Generation Partnership Project (3GPP) latest Release 5 (R5) and Release 6 (R6) specifications. The updated software building blocks are critical components of the Third Generation (3G) network, helping to power the 3G wireless nodes that play an important function in transmission of voice and multi-media traffic across the network. By providing these critical components as standards-based off-the-shelf solutions, CCPU enables wireless equipment providers to focus on developing innovative applications while maintaining their time-to-market advantage.

When new updates are adopted, each cycle either upgrades the capabilities of the existing equipment or defines new protocol and network device specifications. By providing solutions that conform to the recently defined R5 and R6 specifications, CCPU will serve to further the global adoption of 3G technologies by allowing equipment manufacturers to build next-generation wireless products rapidly and robustly, with market-driven feature sets and capabilities. Ultimately, 3G service providers will deploy the upgraded network infrastructure and roll out new end-user services, such as location services, push-to-talk and other killer applications.

"We are very excited to be the first in the industry to offer 3G Wireless protocols supporting 3GPP R6 capabilities," said Prasad Kallur, vice president of Marketing, CCPU. "A key deliverable of the Trillium acquisition was to provide our global customers with the most up to date wireless product portfolio. The addition of R5 and R6 capability proves CCPU remains committed to supporting and continuously enhancing the Trillium product line, and provide timely solutions for our leading edge customers who represent the key architects of the global wireless backbone networks."

The term 3G is an umbrella term covering a range of wireless network technologies. 3GPP is a collaboration agreement between various telecommunications standards bodies, and are responsible for producing the R5 and R6 specifications. Enabling end-to-end IP Convergence, R5 specifications are a major core network release and include new protocol definitions, while R6 defines IP Multimedia Subsystem (IMS) Part II, which also includes in its scope further updates to R5 work items.

3G includes WCDMA, CDMA2000, UMTS, and EDGE. Examples of wireless nodes defined within the 3G network include SGSN, GGSN, RNC, CGF, MSC, NodeB, HLR, and others. CCPU's world-leading protocol software includes solutions for:

-- 3G Core Network (CN) infrastructure including GPRS Mobility

Management/Session Management (GMM/SM), Mobile Application

Part (MAP), Radio Access Network Application Part (RANAP),

Radio Network Subsystem Application Part (RNSAP), CAMEL

Application Part (CAP), GPRS Tunneling Protocol (GTP) and Base

Station Subsystem Application Part (BSSAP+),

-- 3G Radio Network (RN) and User Equipment (UE) including Packet

Data Convergence Protocol (PDCP), Frame Protocol (FP),

Broadcast/Multicast Control (BMC), Radio Resource Control

(RRC), Radio Layer Control (RLC), Media Access Control (MAC)

and Node B application Part (NBAP).

A complementary offering of Trillium SS7, SS7 over IP (SIGTRAN) and VoIP protocols including 3GPP specified Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MEGACO) positions CCPU as a one-stop shop for providing cutting-edge technology solutions.
