A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Robust Header Compression Working Group of the IETF.

	Title		: Signaling Compression Requirements & Assumptions

In wireless environments and especially in cellular systems, e.g. GSM
(Global System for Mobile communications) and UMTS (Universal Mobile
Telecommunications System), there is a need to maximize the transport
efficiency for data over the radio interface. With the introduction
of SIP/SDP (Session Initiation Protocol/Session Description Protocol)
to cellular devices, compression of the signaling messages should be
considered in order to improve both service availability and quality,
mainly by reducing the user idle time, e.g. at call setup. The
purpose of this document is to outline requirements and motivations
for development of a scheme for compression and decompression of
messages from signaling protocols.

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.
