What is a Communications Platform ?
Enable creation, deployment and management of services and applications
that
✓ integrate voice, video and data
✓ across a range of IP and communications network
✓ by multiple devices
●“Any content” + “Any network” + “Any device” = Convergence
●Mobicents Communications Platform drives Convergence by bringing to you the
infrastructure to build your next generation applications

JSLEE - Concepts
Specification Defined by the JCP, v1.1 (JSR 240) just
released
 SLEE = Service Logic Execution Environment

High throughput, low latency event processing.
Built-in support for HA and scalability



Asynchronous support & Event oriented






Elaborated event distribution mechanism (with priority)
Mapping of events and method invocation on components
Creates components instances in response to initial events
Independent of underlying networks through
Resource Adaptors
High performing platform for event driven
applications
SLEE is complementary to Java EE

Server
●
Four Core Capabilities
✓
Integrated Java EE + JSLEE environment

✓
Network abstraction layer

✓


SIP Servlets - Concepts
●
●
Defined by the JCP v1.1 (JSR 289), just achieved Final
Release.
SIP Servlets API :
✓
✓
✓
✓
✓
✓
Familiar to HTTP servlet programmers because it leverages the well
know servlet model to develop SIP applications.
Defines high-level objects
Container provides value-adds such as protocol stack, state
management, proxy & b2bua capabilities, etc.
Ability to mix SIP Servlets and Java EE components to add rich media
interactions to enterprise.
Application Composition through the Application Router
Declarative or programmatic security
Sip-Servlets in Java EE Architecture

Deliver competitive, complete, best-of-breed media
gateway functionality featuring highest quality.
Meet the demands of converged wireless, wireline, cable
broadband access and fixed-mobile converged VoIP
networks from a single media gateway platform
Increase flexibility with a media gateway that supports
wide variety of call control protocols and scales down to
meet the demands of enterprises and small carrier
providers.
React quickly to dynamic market requirements

Mobicents SIP Presence Service:
Overview
●
Provides presence functionalities to SIP-based networks using standards developed by
IETF, OMA, 3GPP & ETSI
Mobicents SIP Presence Service:
Servers
●
●
●
●
The Mobicents Presence Service is made of 3 different
servers:
Mobicents XDM Server: the first free and open
source implementation of an XML Document
Management Server as defined in the OMA XML
Document Management v1.1 specification.
Handles the management of user XML
documents stored on the network side.
Mobicents Presence Server: a free and open
source implementation of a SIP Presence Server,
as defined by IETF, OMA, 3GPP and the ETSI.
Accepts, stores and distributes SIP Presence
Information.
Mobicents Resource List Server: not available
Mobicents SIP Presence Service:
Advantages
●
●
●
●
●
●
Flexible Architecture, deploy servers in separated nodes or all
integraded in a single node
Set of JAIN SLEE components deployed on Mobicents JAIN
SLEE Server, inheriting the power and functionality of the
platform
Uses Jboss AS Datasource and JPA for data storage, easy to
(re)configure
Provides internal JAIN SLEE client interfaces, through child
SBBs, allowing user applications to take advantage of
servers funcionalities
Provides external client interfaces, matching the internal
ones, allowing user applications to be deployed on different
JAIN SLEE servers too, without any code change
Full OPEN-SOURCE stack (Jboss AS + JAIN SLEE Server +
SIP Presence Service), development made easy

Mobicents SIP Servlets Converged
Example
●
●
●
The idea is to have a converged application that shows
how a Java EE application can leverage SIP Servlets to
have voice, message and data transfer seamlessly.
This example is built using Seam, Mobicents SIP
Servlets and Mobicents Media Server deployed on
Jboss
Application
Server.
