I-D ACTION:draft-ietf-simple-message-sessions-00.txt



A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group of the IETF.

	Title		: Instant Message Sessions in SIMPLE
	Author(s)	: B. Campbell et al.
	Filename	: draft-ietf-simple-message-sessions-00.txt
	Pages		: 47
	Date		: 2003-5-23
	
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.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-ietf-simple-message-sessions-00.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
