IMS is an architecture that enables operators to offer advanced multimedia services across circuit-switched and packet-switched networks using SIP for call signaling. It provides a layered approach separating the services, control, and transport planes. 3GPP has specified and enhanced IMS in successive releases to support additional networks and services. IMS allows for convergent applications across networks using common resources and control through SIP. This provides a consistent experience to subscribers regardless of access network.
VoLTE Basic callflows in IMS network v2 - includes Registration, Basic VoLTE Call, SDP, Interconnect, Roaming, highlights important SIP headers for session routing and user identities.
I have described VoLTE IMS Architecture in simplified way . Are you also finding 3GPP Specs complicated & Complex for VoLTE IMS . It covers Role played by individual Networks Elements as mentioned below :-
# VoLTE SIP Handset : SIP Support , UAC , UAS , User Agent , SIP-UA
# Underlying LTE Network : MME , SGW , PGW , PCRF , HSS , Dedicated Bearer , QCI , Default Bearer
# IMS Core : SIP Servers , P-CSCF , I-CSCF , S-CSCF , TAS , MMTEL , BGw , MRF , ATCF , ATGW , IBCF , MGCF , IM-MGW , TrGW
# Voice Core or PSTN Network for Break-in or Break-out Calls

Latter-day growing regulatory environment has emerged organizations to deal with managing of several compliance
frameworks simultaneously. The fulfilment of legal obligations is only one factor that shove the organizations to
robust their management systems. A management system is the framework of processes and procedures used to
ensure that an organization can fulfill all tasks required to achieve its objectives.
In the past few years, a number of things lead operators towards convergence. Mobile handsets and mobile application developers have advanced very fast in the last few years and support lot of new technologies which sometimes network doesn't. Also, all kinds of access devices are allowing people to access an IP centric voice infrastructure
Mise en place d’une plateforme de formation IMSKokou Gaglo
La convergence des réseaux est le moyen par lequel les opérateurs faciliteront à leurs clients un accès facile à leurs services et leurs proposeront des applications innovantes (VoIP, vidéoconférence, messagerie instantanée, jeux multi-joueurs,...). C’est ce défi de convergence entre fixe et mobile que relève la technologie IMS (IP Multimedia Subsystem) en permettant d’être joignable où que l’on soit, sur un ordinateur comme sur un mobile ou autre terminale bénéficiant de l’étendue de l’offre multimedia.

Monetizing VoLTE, RCS and Video; IMS MRF and Conferencing SolutionsRadisys Corporation
Presentation given by Al Balasco, Radisys Sr. Director of Product Management at IMS World Summit on April 23:
Title: Monetizing VoLTE and RCS
• Global trends in LTE, VoLTE, RCS, and other services.
• Strategies to grow revenues beyond data plans
• IMS service delivery architectures for generating revenues from VoLTE and RCS
Convergence of digital information has been initiated a couple decades ago. Practically, almost all networks have now been utilising Internet Protocol. However, networks, applications, and contents managements vary by the nature of service types: IMS, SDP, IPTV, etc. Should another convergence be arranged to unify the management of the entire network for optimal results?

Up to where reaches the mind power? It might be incredible but I think it can reach up to the evolution of the species, it means it can modify the genetic structure o any living form and maintain its evolution.
El poder de la mente hasta donde llega? Es increíble pero llega hasta la evolución de las

2. Definition of IMS…
• IP Multimedia Subsystem (IMS) is an architecture
that enables operators to offer a new generation of
advanced multimedia services
– Across both circuit and packet switched networking
infrastructures
• IMS is a standard that defines an architecture that
uses SIP for call signaling between network
elements
– Provides a layered approach with separated services,
control, and transport planes
3. 3GPP Experience
- 3GPP specified IMS as part of Rel 5 with
improvements in Rel 6
- 3GPP specified UMA as part of Rel 6
- 3GPP added support for I-WLAN in Rel 6
- 3GPP is enhancing IMS to support fixed
broadband in Rel 7
- 3GPP adding Voice Call Continuity in Rel 7
Many IMS based optimizations in Rel 7
IMS Based Multimedia services in Rel 7

5. Key IMS Concepts
• Multiple Plane Architecture
– Makes use of separate planes:
• Application, Transport and Session Control
• Centralized Database
– Single point for all users data HSS. With the use of Diameter
protocol and HSS (Home Subscriber Server) to validate users
• The Subscribers Services are independent of the Access Method
– Enables support for PSTN, 3G mobile, WiFi, GPON, etc.
