This includes IP-based real time services such as voice, video-telephony, machine-to-machine communication, as well as games. With this architecture in place, providers can offer what I like to call session-based services.

What is IP Multimedia Subsystem (IMS)? - Definition from

This breaks the traditional barriers affecting end devices. The ability to decouple the underlying infrastructure from the services delivered is a major benefit of IMS.

From a service provider perspective, IMS allows for new revenue opportunities because multimedia services can be offered over the current IP infrastructure. It enables new converged voice and data services, while allowing for the interoperability of these converged services between internet and ims ip multimedia subsystem subscribers using open standard IP protocols.

Direct interconnection refers to the interconnection between two network domains without any intermediate network domain. Indirect interconnection at one layer refers to the interconnection between two network domains with one or more intermediate network domain s acting as transit networks. The intermediate network domain s provide s transit functionality to the two other network domains.

Different interconnection modes may be used ims ip multimedia subsystem carrying service layer signalling and media traffic.

Charging[ edit ] Offline charging is applied to users who pay for their services periodically e. Online chargingalso known as credit-based charging, is used for prepaid services, or real-time credit control of postpaid services.

Both may be applied to the same session. Charging function addresses are addresses distributed to each IMS entities and provide a common location for each entity to send charging information. Inter Operator Identifier IOI is a globally unique identifier shared between sending and receiving networks.

IMS provides one common system ims ip multimedia subsystem all IP-based communication services, for both consumers and business users.
