Fujitsu and Nokia Siemens to Develop Japanese LTE Network

Fujitsu and Nokia Siemens Networks have agreed to cooperate on jointly developing the Service Architecture Evolution (SAE) Gateway, including the Serving Gateway and the PDN Gateway, for the Super 3G project's Long Term Evolution (LTE) core on behalf of Japan's NTT DoCoMo.

Fujitsu was earlier awarded a supply contract for the core network system Evolved Packet Core (EPC), comprised of S-GW systems, which handle data transmissions with mobile phone handsets, and P-GW systems, which connect the core network to corporate and other external networks.

"We are very pleased to be working with Fujitsu and NTT DoCoMo to advance the progress of LTE," said Juergen Walter, Head of Converged Core, Nokia Siemens Networks. "It is a testament to the quality of our LTE solution and our commitment to the Japanese market."

In LTE, core network functions are performed by the Evolved Packet Core (EPC), which implements voice service in the packet switched domain, fulfilling the goal of networks based on all-IP with access not only from 3G or LTE, but ultimately also WiFi, WiMAX, or even wired access technologies. EPC includes the SAE Gateway and Mobility Management Entity elements, which correspond to the GGSN and SGSN in current 2G/3G packet core networks.

Last month, NEC also won a contract from DoCoMo for the core network system, the Evolved Packet Core (EPC). NEC had already been selected as a Super 3G wireless base station and terminal provider
