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 multimedia core platform 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.
