An Extension for SIP Instant Message Using Publish/Subscribe Mode
draft-zhengjp-sipcore-sipim-ext-01
Abstract
SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions)
is a protocol suite for instant messaging (IM) service, but it is
inefficient in processing session-mode instant message due to its
complex signaling processes and heavy header overheads, which makes
it difficult to meet the QoE (quality of experience) requirement,
especially in the usage scenario of mobile Internet and other traffic
sensitive networks.
This document describes an alternative Session Initiation Protocol
(SIP) extension for instant messaging service. The extension uses the
publish-subscribe mode to simplify signaling procedures and
introduces message user agent (MUA) to publish and receive message,
and message broker (MB) as an intermediary to exchange messages
between MUAs. Message is tagged with a topic, and the lightweight
message format is more suitable for traffic sensitive networks.
