Voice and Video over LTE

Mobile operators have begun migrating to fourth-generation (4G) architectures, which are based on the Long Term Evolution (LTE) standard, including the Third-Generation Partnership Project (3GPP) defined Evolved Packet Core (EPC) architecture.

To offer advanced voice and video over an LTE standard network, you must migrate from circuit-switched voice to packet voice. This requires an architectural vision that supports voice and short message service (SMS) using the existing network and provides a clear path to Session Initiation Protocol (SIP) networks.

This architecture enables new services such as optimized conversational video, presence, and instant messaging. Unlike other solutions based on platforms designed for fixed networks, Cisco Voice and Video over LTE (V2oLTE):

  • Provides a complete solution that includes Circuit Switched Fallback (CSFB), CSFB Interworking Function (CSFB IWF) that can eliminate the need to upgrade legacy circuit switched equipment, and supports the IP Multimedia Subsystem (IMS) framework and recommendations by the One Voice Initiative
  • Meets 3GPP standards and provides continuity within the IMS and circuit domains with superior cost-optimized performance
  • Delivers a complete transition scenario that offers options for deploying IMS immediately or rolling out capabilities over time
  • Delivers the quality experiences mobile consumers have come to expect
  • Helps you manage and charge for mobile services
  • Cisco ASR 5000 Series
    The Cisco ASR 5000 Series supports multiple LTE EPC network functions, including delivery of multimedia services.
  • Cisco Session Control Manager
    This product supports functions that help you migrate from circuit services to packet services.
  • Cisco Converged Services Platform
    This platform supports sophisticated messaging applications and interworking between existing circuit networks and IMS networks.
  • Cisco Services
