/**@MODULEPAGE "soa" - SDP Offer/Answer Engine Module
|
||||
|
||||
@section soa_meta Module Information
|
||||
|
||||
The Sofia SIP @b soa module consists of an asynchronous SDP Offer/Answer engine
|
||||
library. The interface to library is defined in <soa.h>.
|
||||
|
||||
@CONTACT Pekka Pessi <Pekka.Pessi@nokia.com>
|
||||
|
||||
@STATUS @SofiaSIP Core library
|
||||
|
||||
@LICENSE LGPL
|
||||
|
||||
@section soa_oveview Using soa engine
|
||||
|
||||
SIP uses SDP and a negotiation procedure known as "SDP
|
||||
Offer-Answer Model" to establish the multimedia sessions. The
|
||||
SDP Offer-Answer negotiation is specified in
|
||||
<a href="http://ietf.org/rfc/rfc3264.txt">RFC 3264</a>.
|
||||
|
||||
The soa engine is implemented in object-oriented manner. The default soa
|
||||
object just implements the basic SDP negotiation and basic SIP call model. A
|
||||
more complex soa object implementation can manipulate the call model and
|
||||
initiate actions on behalf of application.
|
||||
|
||||
@section soa_model SDP Offer/Answer Model
|
||||
|
||||
The basic capabilities provided by Offer/Answer mechanism include
|
||||
-# generating SDP offer (section 5)
|
||||
-# processing SDP offer, generating SDP answer (section 6)
|
||||
-# processing SDP answer (section 7)
|
||||
-# modifying session (section 8)
|
||||
-# indicating capabilities (section 9)
|
||||
|
||||
The offerer indicates its capabilities in the offer:
|
||||
- the media streams it wants to establish
|
||||
- transport addresses it uses to receive by media streams
|
||||
(IP addresses, port numbers, transport protocols)
|
||||
- the codecs used by particular streams
|
||||
- codec parameters (for instance, codec profile used by H.263)
|
||||
|
||||
The answerer indicates which parts of the offer are acceptable to
|
||||
it in the answer:
|
||||
- the media streams it agrees to establish
|
||||
- transport addresses answerer uses to receive by media streams
|
||||
- the codecs and codec parameters used by particular streams
|
||||
|
||||
Note that the capabilites indicate what the party generating the
|
||||
SDP is prepared to receive. They can send anything the other end
|
||||
accepts.
|
||||
|
||||
There may be other things, like encryption keys included in the
|
||||
session description.
|
||||
|
||||
The advanced capabilities are required by more complicated negotiation
|
||||
involving two or more offer-answer rounds. For instance, an extension known
|
||||
as session <i>preconditions</i> is defined
|
||||
<a href="http://ietf.org/rfc/rfc3312.txt">RFC 3312</a>.
|
||||
Another example of two-phase negotiation is presented in RFC
|
||||
3264 section 10.2, showing how a single codec can be selected.
|
||||
|
||||
@section soa_motivation SOA Design
|
||||
|
||||
Why to have simple interface? Is it not simple enough to include SDP offer
|
||||
with your INVITE, and act on SDP answer in 200 OK?
|
||||
|
||||
Our design goal is to allow application to follow the simple call
|
||||
model, regardless of the underlying complications - early
|
||||
sessions, preconditions, session timers, 3rd party call control.
|
||||
In other words, we would like a have a simple "cooked" interface
|
||||
toward naive applications even if the underlying call follows the
|
||||
byzantine call model chosen by 3GPP.
|
||||
|
||||
@section soa_with_sip Using SDP Offer/Answer with SIP
|
||||
|
||||
Using SDP Offer/Answer with SIP is specified in
|
||||
<a href="http://ietf.org/rfc/rfc3261.txt">RFC 3261</a>,
|
||||
<a href="http://ietf.org/rfc/rfc3262.txt">RFC 3262 (100rel and PRACK)</a>, and
|
||||
<a href="http://ietf.org/rfc/rfc3211.txt">RFC 3311 (UPDATE)</a>.
|
||||
|
||||
There is a @ref soa_sdp_oa_use_cases "separate page listing scenarios".
|
||||
|
||||
The rules for sending offers:
|
||||
- offer may be sent in INVITE
|
||||
- if there was no offer in INVITE, offer MUST be sent in first
|
||||
reliable response to INVITE
|
||||
- offer may be sent in 100rel (reliable 1XX series response)
|
||||
- offer may be sent in PRACK
|
||||
- offer may be sent in UPDATE
|
||||
|
||||
PRACK may only be sent when an unacknowledged 100rel (reliable 1XX
|
||||
series response) is received. UPDATE may be sent during early or
|
||||
established dialog.
|
||||
|
||||
Only one INVITE request may be pending within a dialog. Only one
|
||||
non-INVITE request may be pending within a dialog (in one
|
||||
direction): it is not possible to send UPDATE if no final response
|
||||
has been received to PRACK.
|
||||
|
||||
If there is already an offer/answer exchange in progress, no offer
|
||||
MUST be sent. Offer/answer exchange is in progress if offer has
|
||||
been sent but no answer has been received, or if an offer has been
|
||||
received but no answer has been generated.
|
||||
|
||||
The rules for sending answer:
|
||||
- when offer is received with INVITE
|
||||
- answer MAY be sent with next end-to-end 1XX or 2XX response
|
||||
- answer MUST be sent in a reliable response (100rel or 2XX)
|
||||
- when offer is received in 2XX response
|
||||
- answer MUST be sent in ACK
|
||||
- when offer is received with 100rel response
|
||||
- answer MUST be sent with PRACK
|
||||
- when offer is received with PRACK or UPDATE
|
||||
- answer MUST be sent with 2XX response to PRACK or UPDATE
|
||||
|
||||
Offer or answer in PRACK MUST be processed even if we have already
|
||||
sent 2XX to INVITE.
|
||||
|
||||
The rules for receiving answer:
|
||||
- if offer was sent in INVITE, first session description in any
|
||||
non-error response to INVITE is treated as the answer
|
||||
- if offer was sent in 2XX response, session description in
|
||||
ACK is answer
|
||||
- if offer was sent in 100rel response, session description in
|
||||
PRACK is answer
|
||||
- if offer was sent in PRACK or UPDATE, session description in
|
||||
2XX response is answer
|
||||
|
||||
Rules for situations when endpoint MUST ignore the SDP:
|
||||
- If offer was sent in INVITE, only the first session description in
|
||||
any non-error (1XX or 2XX) response to INVITE is processed, rest
|
||||
are ignored
|
||||
- If no offer was sent in 2XX response to INVITE, SDP in ACK is ignored
|
||||
- If no offer was sent in PRACK, SDP in response to it is ignored
|
||||
- If no offer was sent in UPDATE, SDP in response to it is ignored
|
||||
|
||||
The re-INVITEs and UPDATEs are sent for two different purposes:
|
||||
updating or modifying SIP state, or updating or modifying the
|
||||
associated session. Session timer extension (not yet an rfc) is an
|
||||
example of the first. Putting a call on hold, or adding video to
|
||||
audio-only call is an example of the second. So, upon receiving
|
||||
re-INVITE, there might be quite different things happening. The
|
||||
application can just return a 200 OK with previous SDP, sometimes
|
||||
it must indicate call being on hold and sometimes ask user for
|
||||
permission (for adding video).
|
||||
|
||||
Rules for resolving glare (both endpoints trying to send offer at the same
|
||||
time):
|
||||
- if a offer is received while UAS has generated an offer,
|
||||
it must be rejected (with SIP 491 response).

@subsection soa_uc_early_out Callout with Early Media
|
||||
|
||||
It is possible to establish media session before call is completed. In this
|
||||
case, the 180 Ringing contains the SDP answer. A copy of SDP answer is
|
||||
included in the 200 OK response, too, because the 180 Ringing is not
|
||||
acknowledged and it may be lost.
|
||||
|
||||
This is preferred to the basic call model above, as the endpoints has more
|
||||
time to establish the media session.

@page soa_sdp_oa_use_cases Use Cases for SIP and SDP Offer/Answer
|
||||
|
||||
This page contains a list of use cases or call scenarios for SIP and SDP
|
||||
Offer/Answer.
|
||||
|
||||
There are a few call scenarios that we expect to see when dealing with more
|
||||
telephone-like side of SIP:
|
||||
- calling to existing PSTN networks (early session)
|
||||
- doing resource reservations
|
||||
- calling to 3G IMS
|
||||
- call hunting
|
||||
- having external party setting up your call, etc.
|
||||
|
||||
@section soa_use_case_1 Case #1: Basic Call
|
||||
|
||||
This is the basic SIP call model with the most simple offer-answer exchange.
|
||||
|
||||
<pre>
|
||||
A B
|
||||
| |
|
||||
|----INVITE (offer)---->|
|
||||
| |
|
||||
| |
|
||||
|< - - 180 Ringing - - -|
|
||||
| |
|
||||
| |
|
||||
|<----200 (answer)------|
|
||||
|----------ACK--------->|
|
||||
| |
|
||||
| |
|
||||
</pre>
|
||||
|
||||
@section soa_use_case_2 Case #2: Early Media
|
||||
|
||||
Another case, slightly more complex. The SDP answer is sent with
|
||||
180 Ringing in order to establish an "early session". B might
|
||||
not be a SIP phone, but a gateway to PSTN, for instance. Using this
|
||||
"early session" B can play tones like "burr-burr" or "the
|
||||
subscriber you tried to reach is not in the coverage...":
|
||||
|
||||
<pre>
|
||||
A B
|
||||
| |
|
||||
|----INVITE (offer)---->|
|
||||
| |
|
||||
| |
|
||||
|<----180 (answer)------|
|
||||
| |
|
||||
| |
|
||||
|<----200 (answer')-----|
|
||||
|----------ACK--------->|
|
||||
| |
|
||||
| |
|
||||
</pre>
|
||||
|
||||
After receiving answer in 180 Ringing, A simply ignores SDP in
|
||||
subsequent responses.
|
||||
|
||||
Nothing special here, right? But SIP is not so simple,
|
||||
unfortunately. There are hairy cases because of "early sessions",
|
||||
"forking", "preconditions" and other reasons.
|
||||
|
||||
Now lets go through some hairy cases.
|
||||
|
||||
@section soa_use_case_3 Case #3: Early Dialog, Early Media
|
||||
|
||||
This case is a call using 100rel, early dialog and early media. It
|
||||
is used when the session should be established before call alerts.

||||

||||

@section soa_use_case_4 Case #4: UPDATE with Offer
|
||||
|
||||
This is a call model with two rounds of offer/answer and 100rel.
|
||||
It can be used, for instance, when the endpoints have to make sure
|
||||
that there are enough network capacity for the call to succeed.
|
||||
They can establish a new radio bearer, for instance, before
|
||||
progressing with the call. The initial offer would contain SDP
|
||||
attribute "inactive", the second "sendrev":
|
||||
|
||||

|
||||

|
||||

|
||||
|
||||
Alternative 1 to above, two rounds of offer/answer and 100rel, no
|
||||
UPDATE. It can used, for instance, when caller wants to make sure
|
||||
there is only one audio or video codec that is used during the
|
||||
call. The initial offer would contain SDP attribute "inactive";
|
||||
the second "sendrev":

there is not 2 but 3 offer-answer rounds, allowing A and B to do

precise resource reservations after they have agreed on media,

codecs and transport addresses used during the call:

@section soa_use_case_8 Case #8: Forking

Now, another complication. Here B has two terminals, let say,
|

fixed (B1) and mobile (B2) phone, both alert when B receives a
|
||||
call using procedure known as forking:
|
||||
