5.1. Overview of IMS messaging
IMS messaging takes three forms:
immediate messaging;
session-based messaging;
deferred delivery messaging.
Each form of IMS messaging has its own characteristics; so, even though messaging in its simplest form can be thought of as a single service – after all, all forms of messaging are really about sending a message from A to B – the fact that these characteristics differ makes them each a service on their own. However, the way in which applications are built on top of these services may well hide the fact that these are different forms of messaging. In fact, one of the key requirements for IMS messaging is easy interworking between different messaging types.
