  • 5. System Architecture I-HSPA Network Architecture I-HSPA is a simplified network architecture based on innovative 3GPP standards. I-HSPA system solution, handling HSPA services, enables high capacity and high bitrates optimizing for the 3GPP operators both the network response times and the costs of Packet Switched (PS) network From a technical perspective I-HSPA is a flat architecture: the I-HSPA RAN consists of the I-BTS Network Element, derived from a Nokia Wideband Code Division Multiple Access (WCDMA) BTS plus an I-HSPA Adapter implementing the RNC functionality. Relevant WCDMA BTS generations are Flexi and Ultrasite The I-HSPA radio access architecture which supports standard compliant terminals offers the operators an optimised radio interface for HSPA service I-BTS network element is connected to the 3GPP Core Network (CN) via the 3GPP standard Iu-PS/Gn interfaces I-HSPA flat architecture, an evolutionary step towards LTE, utilizes the Direct Tunnel solution to bypass the SGSN in the User plane with performance benefits (e.g. lower user plane latency) I-HSPA uses Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) network elements to handle mobility The complete solution is centrally managed and operated via OMS and the Nokia Siemens Networks NetAct Framework which provides the operator with a suite of tools to perform network monitoring, configuration, fine tuning, accounting and optimization functions 5 Nokia Siemens Networks RA34051EN02GLA0 RA34051EN02GLA0 5
