<title>Delivering Conference Information to Jingle Participants (Coin)</title>
|
||||
<abstract>This specification defines an XMPP extension for tightly coupled
|
||||
conference calls. It allows users who participate in multiparty Jingle
|
||||
calls via a focus agent (mixer) to retrieve information and receive
|
||||
notifications about the state of the call and the other participants.
|
||||
This extension is also meant to provide a straightforward way of
|
||||
connecting SIP and XMPP clients to the same conference room.

<section1 topic='Introduction' anchor='intro'>
|
||||
<p>&xep0166; defines a way for XMPP agents to establish and control
|
||||
one-to-one media sessions. It is possible for either participant in such a
|
||||
session to also establish additional conversations and then serve as a
|
||||
media mixer. This could be viewed as a classic conference call scenario
|
||||
and is also often referred to as a tightly coupled conference.</p>
|
||||
|
||||
<p>Basic participation or hosting of tightly coupled conferences requires
|
||||
no specific protocol support. With the exception of the mixing agent, call
|
||||
members, however, all perceive the session as a regular one-to-one call.
|
||||
They have no way of obtaining additional information about how many and what
|
||||
other users are participating.</p>
|
||||
|
||||
<p>The Coin extension (short for Conference Information) allows media
|
||||
mixers to deliver to participants additional information about the status
|
||||
of the call, and that of its members.</p>
|
||||
|
||||
<p>A conference participant exchanges Coin IQs only with the agent they
|
||||
have established a session with. This means that it can also be used in
|
||||
cases where only a subset of the users on a call are using XMPP while others
|
||||
are connected via alternative mechanisms such as SIP's conference
|
||||
package &rfc4575;</p>

<dt>Mixer</dt>
|
||||
<dd>Throughout this document the term is used to depict an entity that is
|
||||
responsible for mixing and delivering to conference participants both
|
||||
signalling and media. Other specifications refer to mixers and focus
|
||||
agents as two distinct entities but we find this separation to be
|
||||
unnecessary in the current specification and view both as a single logical
|
||||
entity</dd>

<section1 topic='Requirements' anchor='reqs'>
|
||||
<p>The extension defined herein is designed to meet the following
|
||||
requirements:</p>
|
||||
<ol>
|
||||
<li>Provide a means for mixer agents in tightly coupled
|
||||
conferences to advertise call and member state information to the call
|
||||
participants.</li>
|
||||
<li>Reuse as much as possible the existing format and XML schema already
|
||||
defined in <cite>RFC 4575</cite>.</li>
|
||||
<li>Impose no requirements on agents joining the call other than those
|
||||
necessary to establish a regular one-to-one call.</li>
|
||||
<li>Allow straightforward interoperability with other conferencing
|
||||
mechanisms such as <cite>RFC 4575</cite>; or &xep0272;</li>
|
||||
</ol>

<section1 topic='How It Works' anchor='howitworks'>
|
||||
<p>This section provides a friendly introduction to Coin.</p>
|
||||
<p>In essence Coin allows clients that establish Jingle calls to
|
||||
determine whether their peer is acting as a mixer or to announce themselves
|
||||
as such. This way non-mixer participants would know when they are
|
||||
participating in a conference call and would be able to notify the user
|
||||
accordingly.</p>
|
||||
|
||||
|
||||
<p>Once in a call, call members and mixers can use Coin to exchange
|
||||
<cite>RFC 4575</cite> conference information indicating what participants
|
||||
are currently on the call and what their status is.</p>
|
||||
</section1>
|
||||
<section1 topic='Creating a conference call' anchor='call-create'>
|
||||
<p>When creating conference calls mixers SHOULD indicate the nature of the
|
||||
call as early as possible. This is necessary in order to allow other
|
||||
participating user agents to adapt their user interface in an appropriate
|
||||
way.</p>

|
||||
<p>Similarly mixers being dialed by new participants SHOULD indicate the
|
||||
nature of the call by including the <conference-info/> element into
|
||||
the Jingle session-accept message.</p>
|
||||
<p>Finally, when transforming an existing one-to-one session into a
|
||||
conference or vice-versa a mixer SHOULD send a Jingle session-info message
|
||||
with the appropriate <conference-info/> element. </p>
|
||||
<p>Note that presence of the <conference-info/> element is only
|
||||
determines whether the party sending it is currently acting as a mixer or
|
||||
not. If multiple peers in a call are independently acting as mixers they
|
||||
should all indicate their status accordingly.</p>

<p>Once a conference call has been established and advertised as such, a

<p>In order for an application to determine whether an entity supports this
