Operators around the world have been rapidly deploying 3G network technologies to support increasing subscriber demand for mobile broadband services. These technologies include:
- Universal Mobile Telecommunications Service (UMTS) high-speed packet access (HSPA)
- Code Division Multiple Access that is Evolution-Data Optimized (CDMA2000 1xEV-DO)
Mobile operators will continue to evolve their core networks to the Long Term Evolution (LTE) Evolved Packet Core (EPC) specification to provide:
- Multi-megabit bandwidth
- Latency reduction
- Improved mobility
When deployed in 3G networks, the Cisco ASR 5000 Series simplifies migration to LTE EPC through a software upgrade, without requiring extensive changes or equipment. Cisco ASR 5000 can serve as the following, either separately or integrated into a single platform:
- Cisco MME Mobility Management Entity
- Cisco PGW Packet Data Network Gateway
- Cisco SGW Serving Gateway
- Cisco ePDG Evolved Packet Data Gateway
- Cisco SGSN Serving GPRS Support Node Release 8
- HRPD Serving Gateway
Many operators are already planning for their 4G core network. Cisco is ready with strategies and solutions that will enhance operators' existing 3G networks and meet their 4G EPC requirements.
ASR 5000 Series supports multiple LTE EPC network functions.
Learn how the MME manages session states, mobility, and authentication in LTE networks.
Learn how the PGW acts as an interface between the LTE network and other packet data networks.
Learn how the SGW serves as the local mobility anchor.
Learn how the ePDG connects the EPC network and fixed non-3GPP networks.

Cisco Virtualized Packet Core (VPC)
Capture untapped revenue opportunities, particularly with the proliferation of Internet of Everything (IoE) and machine-to-machine (M2M) connections. As one of the industry's first commercial virtualized evolved packet cores, the new Cisco Virtualized Packet Core (VPC) solution redefines the paradigm of agility for service providers.
VPC combines all packet core services-for 4G, 3G, 2G, Wi-Fi, and small cell networks-into a single solution. It provides those network functions as virtualized services, so you can scale capacity and introduce new services much faster and more cost-effectively.
