Vendors quantify opex saving and time-to-market benefits of IMS

摘要

The IMS business case will be as much about reducing churn and opex and accelerating time-to-market as it is about earning revenues from lucrative new applications, vendors say. The IMS advantage lies in its ability to combine services, thereby locking in the end user and setting up applications rapidly, potentially for a relatively small user base that it would not have been viable to serve before. Vendors say that, according to operator business cases, IMS and core-network upgrades can reduce a carrier's operational costs substantially - 20-25%, according to Lucent, or 38%, according to IBM. Cisco suggests that a 10 million-subscriber network is able to see an operational saving of US$50-80 million over three to four years, largely in the transport portion of the networks.
