The IP Multimedia Subsystem is the standard architectural framework developed to deliver IP multimedia services to businesses around the world. It was originally conceived by the 3GPP or 3rd Generation Partnership Project for creating networks that could work beyond GSM. This latest multimedia subsystem is going to help telecom companies leverage the future IMS networks in order to provide services to the SMB market. This architectural framework, or IMS-PBX solution, facilitates the integration of video, voice, IM/Presence, video and voice conferencing over different devices – all this provides seamless communication experience while using unified communication systems.
Benefits of IP Multimedia Subsystems
There are several benefits of using the IP multimedia subsystem; however, the one benefit that stands out is the higher profits that can be realized by businesses when they are able to seamlessly connect their fixed lines, smartphones and web devices. This is a solution that is determined to facilitate efficient functioning across multiple devices in a very simple, native and intuitive manner.
It is the era of BYOD and other revolutionary technologies, and, in order to leverage the existing mobile telephony infrastructure, it is imperative that we avail IMS. The IP multimedia subsystem is a perfect solution to provide robust support to Enterprise Mobility, Advanced PBX Features, Virtual Business Lines, Enterprise Collaboration Services and VoIP devices. With the help of IMS, operators are better placed to develop differentiated and exciting services that will target SMBs. These services will be both cost effective and feature-rich, which is the ultimate priority of all SMBs.
In order to facilitate easy integration of Internet and IMS, it uses IETF protocols like SIP (Session Initiation Protocol) wherever required. 3GPP has built IMS with the sole objective of aiding the multimedia and voice application access from wired and wireless terminals.
IMS does not intend to standardize any application. It is here to facilitate and build a type of FMC or fixed-mobile convergence. This is achieved with the help of the horizontal control layer which isolates network access from its service layer. If we are to look at it from the architectural perspective then the services are not required to possess any control functions as that is achieved by the horizontal layer, which is common to all.
