FLat IP Architecture
To meet customer demand for real-time data applications delivered
over mobile broadband networks, wireless operators are turning to
flat IP network architectures.
The key benefits of flat IP architectures are:
- lower costs
- reduced system latency
- decoupled radio access and core network evolution
Key players in recognizing these advantages are:
- Mobile Networks
- 3rd Generation Partnership Project (3GPP)
- 3GPP2 standards organizations
- WiMAX Forum.
In assessing the implementation of a flat IP architecture, network
operators are analyzing the strategies and product roadmaps of leading
equipment suppliers. They are seeking out those looking to support
operators in the move to next-generation mobile broadband.
Key considerations of Flat IP Architectures for Mobile Networks
- Advanced base stations that integrate radio control, header
compression, encryption, call admission control, and policy enforcement
with IP/Ethernet interfaces.
- Base station routers will provide simpler, lower-latency 3GPP/2
networks. Key emerging players are: Alcatel-Lucent, Airvana, and
- The Direct Tunnel Architecture is emerging as the most viable
evolution path for W-CDMA macro networks. Current implementations
include Nokia-Siemens's Internet High Speed Packet Access architecture
and Ericsson's Serving GPRS Support Node bypass initiative.
The WiMax Access Services Network is the first standardized IP-centric
mobile network architecture establishing principles now being adopted
across the industry; however, vendor interoperability remains challenging
