"Instant Message Sessions in SIMPLE", Jonathan Rosenberg, Ben Campbell, 06-MAR-03,
The SIP MESSAGE method is used to send instant messages, where each message is independent of any other message. This is often called pager-mode messaging, due to the fact that this model is similar to that of most two-way pager devices. Another model is called session-mode. In session-mode, the instant messages are part of a media session that provides ordering, a security context, and other functions. This media session is established using a SIP INVITE, just as an audio or video session would be established. This document describes a The Message Session Relay Protocol (MSRP), a mechanism for transmitting session-mode messages with minimal relay support. Additionally, this document describes using the SDP offer/ answer model to initiate such sessions.

Abstract Instant Messaging (IM) refers to the transfer of messages between users in near real-time. These messages are usually, but not required to be, short. IMs are often used in a conversational mode, that is, the transfer of messages back and forth is fast enough for participants to maintain an interactive conversation. Each message can be sent independently using the SIP MESSAGE method, or messages can be associated into sessions that are initiated using SIP. The first approach is often referred to as pager-mode messaging, due to its similarity to the behavior of two way pager devices. The second approach is often called session-mode messaging, or simply message sessions. This document describes a message session mechanism based on the Common Presence and Instant Messaging message format.
