SFR, which serves more than 20 million mobile customers across France, has selected Cisco to expand and enhance its mobile Internet network in order to accelerate the deployment of LTE services.
SFR will leverage Cisco's next-generation Internet architecture, including elastic packet core, mobile backhaul, and service provider Wi-Fi solutions, t odeploy the widest range of heterogeneous radio networks (2G/3G, 4G LTE, Wi-Fi), capture new business opportunities, foster new business models and meet rapidly growing network demands.
The Cisco Elastic Packet Core will provide 4G LTE Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PGW), 2G/3G GGSN and SGSN applications. The MME is critical to the network function of the 4G LTE network. The Cisco MME manages multiple back-end functions, including authentication, paging, mobility with 3GPP 2G and 3G nodes, roaming and other functions. The Cisco Serving Gateway (SGW) and the Cisco Packet Data Network Gateway (PGW) are two essential elements to SFR’s 4G LTE mobile network. The Cisco SGW provides superior throughput and processing, while the Cisco PGW acts as policy enforcement, managing quality of service (QoS).
SFR is also deploying the Cisco ASR 901 and Cisco ASR 903 mobile backhaul solutions.
In addition to SFR’s 4G deployment, Cisco will also support the service provider’s 2G and 3G cellular networks with its Cisco Gateway GPRS Support Node (GGSN) and Cisco Serving GPRS Support Node (SGSN).
