PrintFlexi Network Server
The high transaction capacity of Flexi NS plays an important role in the flat architecture due to the increased requirements on signaling. This differentiates Flexi NS from other vendors’ SGSN/MME solutions, which focus only on the subscriber database size.
In addition to high performance, environmental impaCT is an important part of the Flexi NS design. This is reflected in the very small footprint and low energy consumption of Flexi NS.
Emerging network technologies like HSPA enable higher data rates compared to more traditional 2G/3G network access technologies. The available data rate in the radio network increases even further with HSPA+ and flat architectures (e.g. I-HSPA, direct tunnel and Long Term Evolution).
Due to higher bitrates, PC data cards and dongles are becoming increasingly popular in addition to mobile terminals. Voice is also migrating from the circuit-switched domain to the packet-switched domain. The two trends require higher throughput and increased signaling handling performance due to flat architectures. Flat architectures optimize the network topology and reduce the cost of transferring end-user data.
Flexi NS is the product to address increased demand for transactions and simultaneous sessions with superior signaling capacity provided by high-performance multi-processor ATCA-based architecture.
The business benefits
- Decrease OPEX with flat architecture and high-capacity elements
- Flexi NS serves more smartphones due to market-leading signaling capacity
- Very efficient SGSN/MME with a power consumption of only 59W per 100k subscribers
- Flexible HW scalability based on ATCA (Open Core System)
- Future-proof investment by software upgrade to LTE
