Alcatel-Lucent Media Resource Function
R EL E A S E 7.1
The Alcatel-Lucent Media Resource Function (MRF) is a comprehensive software product, fulfilling the role
of a powerful media server in packet-switched networks and allowing quick deployment of a range of
value-added services.
The Alcatel-Lucent MRF can be used
as either a standalone node to provide
basic announcement services, or as a
node for an IP Multimedia Subsystem
(IMS), Long Term Evolution (LTE), CDMA,
Universal Mobile Telecommunications
System (UMTS), next-generationnetwork (NGN) or WiMax network. As the
latter type of node, the product plays a
key role in many media-related services:
• Playing multilingual fixed and
variable audio announcements
• Playing video announcements
• Collecting dual-tone multi-frequency
(DTMF) for user interaction
• Providing audio and video conferencing, selecting the video stream,
with mixing of audio streams and
coders/decoders (CODECs) transcoding
• Performing legal interception, thanks
to its media-stream duplication
capability
The use of a full-software mediaprocessing technology provides a very
competitive solution with reduced
costs and reduced time-to-market
for feature improvements because
no digital signal processors (DSPs) are
used. The Alcatel-Lucent MRF is also
a rich application-protocol solution
that supports all major interfaces,
including Network Announcement
protocol (NETANN), Media Server
Control Markup Language (MSCML),
Media Session Markup Language
(MSML), Alcatel-Lucent Media Session
Markup Language AMSML and voice
eXtensible Markup Language
(vXML) script.
Key features
• Playback of prerecorded fixed and
variable announcements, such as
phone number, prices, date, time,
duration and integer numbers,
including in a multilingual
environment
• Textual announcements played using
optional speech synthesis, such as
text-to-speech (TTS) technology for
all supported audio CODECs
• Playback of video announcements
• Recording of audio and video
announcements
• DTMF detection: collection of user
interactions through:
¬ Out-band user-plane DTMF
detection
¬ Out-band control-plane DTMF
detection
¬ In-band DTMF detection for
CODEC G711 a-law or µ-law and
in video sessions
• Conferencing:
¬ Channel mixing for audio confer-
ence accepts any of the supported
CODECs; the necessary transcoding
is transparent to the application
¬ Video conferencing (MSCML):
accepts any of the supported
CODECs; the necessary transcoding
is transparent to the application,
the loudest speaker video stream
is broadcasted to all conferees
¬ Recording
• Lawful interception
• CODEC transcoding: conference,
announcement playback
• Collection of user interactions
through:
¬ DTMF detection: out-band
and in-band
¬ Optional speech-recognition
technology
Key benefits
• Supports multiple languages (more
than 80) and variable announcements
• Supports a variety of CODECs; the
software-based architecture also
makes it simpler and less expensive
to introduce a new CODEC than with
a DSP-based architecture
• Delivers multiservices: platform
can interact with several services
simultaneously, generating economyof-scale savings
• Fully integrates with Alcatel-Lucent
solutions
• Supports multiple application
protocols, facilitating integration
with third-party services
• Provides multinetworking: using
the Alcatel-Lucent MRF and the
Alcatel-Lucent Specialized Resource
Point (SRP), customers can broadcast
announcements over TDM and IP
networks with a single operation
• Offers high scalability: seamless
scalability ensures efficient capacity
expansions
• Delivers carrier-grade services: provides quality voice and video services
with highest availability
• Supports Quality of Service (QoS):
differentiated services code point
(DSCP) marking to differentiate the
flow according to RFC 4594
