IMS (IP Multimedia Subsystem) developments, and the whole fixed-mobile convergence concept of managing and delivering services across a single core network, have gained major momentum in past months, with standards bodies making progress and vendors and operators announcing IMS-based strategies (see IMS Tops 3GSM Agenda, IP Multimedia Subsystems: Easy Does It, and Vendors Prep for IMS Fight).
IMS is set to enable next-generation applications like multimedia conferencing, multiplayer gaming, and transferring a voice-over-WLAN call to a cellular network. It will have a major impact on the telecom industry because it will lead to new business models and opportunities and (it is to be hoped) lower costs through standards-based procurement.
In short, it’s important. Very important. But it’s also very complex.
Which is why Light Reading has put together an IMS Guide, to help you understand this technological minefield.
Author Tim Hills lays out the basics in a report that makes IMS easy to follow:
- What Is IMS?
A unified service architecture for all networks
- Why Is It Important?
It's life after the bit-pipe
- What Is the State of Standards?
Work in progress, but solid results
- How Does IMS Work?
- Are There Issues With the Technology?
It's still early days
- What Does IMS Mean for Legacy Circuit-Switched Networks?
Higher revenues if telcos are smart
- What Can IMS Be Used For?
Everything from tailored applications to the next big thing
- Who Would Deploy IMS?
Just about everyone could be interested, one way or another
There are a lot
