Huawei Dials World First Long-Distance WCDMA VoIP Call Based on 3GPP R4
April 15, 2003
Huawei Technologies, a supplier of telecom infrastructure, announced
that it has successfully made the global first R4-based long-distance
VoIP call between Beijing and Shenzhen with its WCDMA gear.
On February 26, 2003, Huawei made the VoIP call experiment in its own
WCDMA trial networks located in Shenzhen and Beijing, using its core network
equipment that consist of an MSC Server and a Media Gateway (MGW) in its
Shenzhen network and another MGW in its Beijing network.
Between the two cities far apart geographically, all of the voice and
signaling traffic of WCDMA call are transported via IP-based Wide Area
Network (WAN), and the connection speed and quality of voice service are
quite satisfactory to a wide range of visitors from the industry and its
customers during the demonstration period.
Leveraging soft-switch architecture, Huawei's 3G core network is capable
of increasing service deployment efficiency by 300% for the whole network,
thus reducing network OPEX by a large margin.
"We will continue to carry on our 3G experiment on condition of the high
density traffic in order to test the QoS of the long-distance IP bearer,"said
Mr. Chengdong Yu, Vice President of Huawei Technologies and Chief Director
of the company's wireless products, "and we must get things done ahead
of our customers to secure our preemptive launch of the VoIP technologies
and applications. I'm happy that Huawei has made such a technology achievement
of quickly delivering the state-of-the-art solutions for 3G."
Following the official release of its commercial 3G core network based
on soft switch architecture in Dec. 2002, the VoIP experiment is a milestone
event for Huawei's 3G launches, and a sign of teamwork efficiency among
experts, engineers and executives of Huawei's global research networks.
