IMS Architecture
Description
This course presents the architecture and functionalities of the IP Multimedia Subsystem (IMS) as defined in the current R17 3GPP standards. IMS as a generic platform designed to control and handle a variety of services accessible over several possible access networks is explained. The course shortly introduces the different possible IP Connectivity Access Networks (IP-CANs) that IMS can handle, but is mainly access-agnostic. There is a definite focus on the mobile access option from the 3GPP standards - mainly 4G and 5G – with mainly the telephony (VoLTE/Vo5G) service used as an example. The course presents the benefits of deploying IMS control: service availability and subscription verific…Foire aux questions (FAQ)

This course presents the architecture and functionalities of the IP
Multimedia Subsystem (IMS) as defined in the current R17 3GPP
standards. IMS as a generic platform designed to control and handle
a variety of services accessible over several possible access
networks is explained. The course shortly introduces the different
possible IP Connectivity Access Networks (IP-CANs) that IMS can
handle, but is mainly access-agnostic. There is a definite focus on
the mobile access option from the 3GPP standards - mainly 4G and 5G
– with mainly the telephony (VoLTE/Vo5G) service used as an
example. The course presents the benefits of deploying IMS control:
service availability and subscription verification, session
handling, security, charging. Session establishment, modification,
and release, together with the policy management for resources
within the used IP-CAN are discussed. Mobility-related and roaming
considerations for mobile/nomadic devices are also presented.
