Nokia Siemens Networks' solution will enable China Mobile to increase its packet core network capacity cost-efficiently as well as to launch new mobile data applications. It will provide one of the highest and most intensively tested user capacities in the market.

"As the telecommunications service provider for Beijing 2008 Olympic Games, our goal is to provide advanced technology, rich applications and high quality services to respond to the needs of our customers. This expansion paves the way for convenient data services by using a proven platform supplied by Nokia Siemens Networks." commented Mr. Li Zhijie, Deputy General Manager of Network Department, China Mobile Group Beijing Ltd.

"We are very proud to further cooperate with China Mobile Group Beijing for its GPRS expansion to allow mobile users to enjoy high quality voice and high speed mobile data services such as Push to Talk, Express News, streaming through Nokia Siemens Networks' GPRS Platform," said Zhang Zhiqiang, Head of Nokia Siemens Networks Greater China Region.

The high user capacity of the packet core solution from Nokia Siemens Networks allows operators to handle a huge number of mobile consumers, even if they are using data services heavily, with a very small amount of equipment. One part of the solution, the Serving GPRS Support Node (SGSN), combines support for 2G and 3G networks dynamically in one system. Operators are therefore free to devote available capacity to the network where the capacity is needed without adding new hardware.

The SGSN also prepares an operator's network for the so called "direct tunnel architecture" or "flat architecture". This architecture is part of the Long Term Evolution (LTE) of mobile data networks. With this technology the payload of the connection will be handled directly between access and the GGSN. Only the signalling part has to be routed through the SGSN. This saves a lot of capacity in the SGSN, so an increase in traffic doesn't mean an additional investment in this part of the network.

Nokia Siemens Networks is a leading packet core supplier and has more than 270 GPRS references globally. It serves more than 400 million GPRS subscribers on all continents Recent launches include a solution for content based charging for China market, policy enforcement including peer-to-peer application detection and service bandwidth management feature that are helping operator to protect valuable network resource in cost efficiency way and at the same time continuously driving standardized packet core network evolutions.
