This paper focuses on the delivery of personalized VoLTE and mobile video services using IMS across both wired and wireless networks. IMS has evolved from 3G to LTE, creating a foundation for delivering ubiquitous communication services that create new opportunities for communications service providers. Through the thoughtful deployment of IMS architecture—a relatively small incremental investment relative to LTE access and core IP network infrastructure investments—service providers will ultimately generate more revenue and ARPU.
This infrastructure provides full media processing support for Voice over LTE (VoLTE), Rich Communications Suite (RCS), voice mixing, video mail, video ring-back tones and video conferencing with live video share, among other services. Underlying all these real-time communication services is the Media Resource Function (MRF) in the IMS, which supports the types of mobile applications and services that are forecasted to explode in the coming years.
