What is an IMS core?
What is an IMS core?
IMS core elements are primarily responsible for handing (routing) Session Initiation Protocol (SIP) traffic, as the signaling mechanism of choice for public communications network infrastructures. The Diameter protocol is also widely employed, within the IMS core, for policy control and billing.
Is IMS part of core network?
IMS specification began in 3GPP Release 5 as part of the core network evolution from circuit-switching to packet-switching and was refined by subsequent Releases 6 and 7.
What are IMS components?
An IMS powered UE has two main components.
- Universal Integrated Circuit Card (UICC)
- Session Initiation Protocol User Agent (SIP UA)
