Hutchison 3G Austria flattens its world with "direct tunnel"
Flat network architecture solution ensures better performance and operational savings
The so-called direct tunnel functionality, which Nokia Siemens Networks has pioneered, is an innovative software upgrade that simplifies the packet core network and the data flow between the end-user and the Internet. By modernizing its packet core, Hutchison 3G Austria boosts its network performance to higher speeds and capacity to handle all its data traffic through a single node for the foreseeable future. Direct tunnel also offers a clear migration path to future mobile network technologies, like Long Term Evolution (LTE).
"To provide our subscribers with state-of-the-art online services, along with high-quality voice, we needed a solution that would help expand network capacity without major infrastructure expansion," said Jan Trionow, CTO of Hutchison 3G Austria. "The flat network solution from Nokia Siemens Networks means fewer network elements, better performance, greater flexibility and lower operational costs."
With direct tunnel functionality, Nokia Siemens Networks is introducing innovative flat core architecture into today's 3G networks, allowing data traffic to bypass the Serving Gateway Support Node (SGSN), which in traditional core setup is responsible for the signaling and user data at the same time. Thus the direct tunnel feature, by bypassing SGSN, reduces the load on its capacity and lowers transmission network costs. It allows operators to balance the use of network resources and prepare for LTE and the streamlined core networks of the future. In addition to the SGSN and the direct tunnel feature, Nokia Siemens Networks also is providing 3G Austria with the NetAct network management and service management solution for maximizing network performance as well as implementation services.
"This implementation confirms our leadership in wide scale global direct tunnel deployments," said Dietmar Appeltauer, Head of Central East Europe at Nokia Siemens Networks. "The extensive testing by Hutchison 3G Austria and live experience further verified positive results from our earlier deployments."
Nokia Siemens Networks is the world's number one vendor in direct tunnel deployments with over 15 customers in all major markets since delivering its first commercial solution in 2007. Nokia Siemens Networks continues to drive the market for direct tunnel and Internet HSPA thanks to the experience gained from these commercial projects and wide-scale testing, also in several multivendor networks. Nokia Siemens Networks is well on track to supplying its robust, high-performance direct tunnel solution to 30 customers by the end of 2008.
Hutchison 3G Austria GmbH started in May 2003 with the brand 3 as the first sole mobile multi media provider in Austria. 3 offers multimedia products such as video calling, music videos and mobile television on the UMTS-mobile and in addition provides the classic ways of communication (voice calling, SMS and MMS). 3 disposes of 41 mobileTV and radio channels which are available for free (excl. erotic channels). In 2007 3 has started HD mobileTV as the first mobile network provider in the world on special handsets as a new standard for better picture quality. Besides 3 has enriched its offer with the "X-Series" in May 2007: Popular internet services such as Skype, Yahoo, Google, eBay, Windows Live, Sling and Orb are available on selected 3mobile phones. In May 2008 Hutchison launched DVB-H in Austria. Hutchison 3G Austria GmbH counts more than 555.555 customers (as per May 2008), 17,3 Mio. customers worldwide, and is wholly owned by Hutchison Whampoa Limited in Hong Kong.
