Alcatel-Lucent Evolium 7500 SGSN / 7720 iGGSN
Alcatel-Lucent’s GGSN and SGSN have had a difficult time matching the performance of competitors. Future EPC offers hold out hope for better LTE support – but also suggest that the vendor is ceding the current market to competitors. (7/6/2009)

Cisco eGGSN 2.0 Release 3.0
Cisco’s routing history makes it a trusted IP player and its SAMI upgrades improved the performance of its GGSN. However, competitor upgrades and the lack of a SGSN may hold its 3GPP packet core solution back. (8/14/2009)

Ericsson SGSN 2009A/ GGSN 2009A
Beyond new names, Ericsson’s SGSN and GGSN remain very much the same. This means they’re still solid products, but open to increasing competition – and even the threat of a stronger R&D focus on Ericsson’s SmartEdge-based EPC kit. (7/6/2009)

Huawei SGSN9810/GGSN9811
Huawei’s 3GPP packet core solution can claim incredible SGSN capacity and solid (if not stellar) GGSN scalability. Recent upgrades delivering impressive performance boosts across the portfolio, however, question the proven nature of the claim. (7/6/2009)

Nokia Siemens Networks Combi SGSN / Flexi ISN (Flexi Network Gateway)
The Flexi Network Gateway promises session and throughput scalability that can only be called incredible. In the here and now, however, a lack of commercial references leaves the less than threatening Flexi ISN as the company’s GGSN offer. (7/6/2009)

Starent Networks ST16 / ST40 Intelligent Mobile Gateway
While solid capacity and service support have been hallmarks of the solution, competitor updates have encroached on Starent’s 3GPP mobile core offer. Upgrades planned for July promise to close that gap, but will still need to be market proven. (7/6/2009)

• Buying Criteria
  • Scalability and Density
    • The number of active PDP contexts supported for mobile data sessions as well as how efficiently the scale is supported.
  • 3G Service Capabilities
    • The extent of feature support that furthers the operation of the packet switched domain in a mobile network. This includes consideration of QoS, lawful intercept, and any optimizations provided by the vendor.
  • Value-Added Service Capabilities
    • The extent of feature support that enables operator deployed services beyond simple packet transport over mobile wireless networks. These features must have potential for increasing the revenue contributions from the wireless data service.
  • Billing Capabilities
    • The extent of support for post-paid and pre-paid data billing.
  • Market Momentum and Vision
    • Factors such as market share, recent product momentum, and innovation that could impact purchase decisions.
