Singapore-based StarHub has migrated its 3G core network to a flat network architecture using Nokia Siemes Networks’ Direct Tunnel solution. This expansion will strengthen StarHub’s HSPA+ (High Speed Packet Access)-based wireless broadband service, which offers speeds of 21 Mbps and up. Financial terms were not disclosed.
“Data traffic has increased exponentially over the last two years, and StarHub is now geared to handle the current and future traffic needs of its subscribers. What’s more, there is no need to invest substantial amounts of money to build capacity to handle the increased data throughput. It’s really thanks to this innovative software offering from Nokia Siemens Networks that routes 3G data traffic effectively, improving the user experience while reducing capital and operating expenses,” said Peter Cook, Vice-President of Integrated Network Engineering, StarHub.
Direct Tunneling allows user data traffic to bypass the Serving Gateway Support Node (SGSN), which, in traditional packet core setups, is responsible for both signaling and routing user data. When user data bypasses the SGSN, it reduces the load on the SGSN capacity and lowers transmission network costs. Further, with Nokia Siemens Networks as StarHub’s incumbent packet core solution vendor, the Direct Tunneling functionality is a mere software upgrade for the operator.
