Cisco Packet Data Network Gateway (PGW) is a critical network function for the 4G mobile core network, known as the evolved packet core (EPC). The PGW acts as the interface between the LTE network and other packet data networks, such as the Internet or SIP-based IMS networks.. The PGW serves as the anchor point for network mobility and:
The PGW function is supported on the Cisco ASR 5000 Series and delivers the high performance throughput, call transaction rates, packet processing, and significant memory resources required for mobile broadband.
EPC: Defining a Simplified Mobile Network
EPC specifications define a simplified network architecture. The Cisco PGW can further simplify the network acting as a standalone element or integrated with other EPC elements, such as:
By combining these functions into a single carrier-class platform, like the ASR 5000, operators can reduce signaling overhead, distribute session management, and maximize the control and user plane capabilities.
