IMS - What are we talking about ?

IMS is a standardized IP control Domain for new MM services

IMS has been standardized by 3GPP in R5 (June 2002)

IMS enables peer to peer multimedia communication over Packet Networks

It uses SIP the protocol of choice for IP-based service control

It provides MM call control completing GPRS and UMTS infrastructure


Why SIP is the Protocol of Choice for Multimedia Some SIP basics (Session Initiation Protocol)

SIP is standardised by IETF for VoIP and Multimedia

Succesor for ITUs H.323 (VoIP)

IP based Protocol (Sign. over UDP or TCP)

SIP is text based, very flexible and simple

Only 7 types of messages (methods)

Same session setup for all medias (different codecs)

SDP (session description protocol – capability negotiation)

Always included in SIP

Easy handling of different media streams (QoS)

3GPP defined extensions for IETF SIP

Optimized Reference Architecture

SIP Header Extensions

Better QoS, Security and Charging features


Comparison of IETF and 3GPP SIPTarget: The best of two worlds (IT and Telco)

IETF IETF defines lots of

protocols Internet paradigm Endpoint centric Security becomes more

important Charging is of minor

importance (flat rate)

3GPP Defines an architecture

which uses protocols Operator paradigm Core network centric Security is one of the most

important topics Charging is one of the most

important topics

IETF SIP 3GPP SIP

SIP Only a few 3GPP specific headers remain

Most of the SIPprotocol is generic


Status of IMS in 3GPP

3GPP Rel. 5 Specs were finished in 05/2002

Stage 1 & 2 standards: requirements and functional architecture, basic features

Enhanced features --> Rel’6

3GPP Rel. 6 Specs were finished in 09/2003

Reduce OPEX and CAPEXIMS is an access-independent Service Delivery Platform

Enables Operators to have one homogeneous service platform for all packet based access networks (OPEX & CAPEX savings!)

Enables service interworking between different access technologies

Push-to-talk enables instantaneous half-duplex voice communications 1-to-many (voice message distribution) 1-to-1 (“walkie talkie” service; a special case of 1-to-many

model) Many-to-many (conferencing service)

Nextel’s success with Push-to-talk has lead to a market pressure in the U.S. Other operators now want to copy Nextel‘s business model.

Other Use Cases of IMS


IMS – Pushing New Services Ideas of bundled PoC applications

Enhancement of Push to talk over Cellular by bundling with Presence / Location

> All contacts at a glance with one single Buddy-List > Information of the availability of the contacts/buddies including terminal capabilities & preferences, moods and locations

Chatting/ Messaging> Creation of a common communication portal with text and voice based communication applications

Photo Shots & Video Streams> During a PoC conversation, instant picture shots or short video clips can be streamed to the other party, by simply pressing a button


IMS – Pushing New Services Use cases of bundled PoC applications

PoC_Presence& Location

PoC_Chat

PoC_Push-to-Watch

You have a PoC Session with your buddies and during this session you want to show them where you are.Push-to-watch and pictures of you and your surrounding will instantly be streamed to your friend while talking!

During an ongoing PoC sessionyou want to inform one of your buddies about an important aspect - in private -:

Invite him for a chat!

You initiate a PoC session with your team asking for important information:

one of them will answer by PoC_Call (voice based)

and another by PoC_Chat (text based)


IMS – Pushing New Services Short description of Video Telephony

Video Telephony

enables you to a more natural form of communication

gives you the opportunity to talk and to see your partner (& its surrounding) during your conversation in real-time

has a camera function, which can be flexibly switched on/off

can be enhanced with Presence, Conferencing, Collaboration tools like document sharing, etc.

93% of communicationis what we see


IMS – Pushing New Services Use cases of Video Telephony

Share a moment with family/friends: “Hi Brian, I would like to show you where I am right now!

Families living apart – Dad is on a lot of business trips, but still wants to see his kids; and they want to see, where he is.

Surveillance: Baby-phone: “How is my baby doing?” On vacation: “Is everything o.k. at home?”

Remote Diagnostics for medicine, technical experts, car repair, etc.


IMS – Pushing New Services Short description of Information Sharing

Display Sharing> Share the view: You able to see what is on my screen> With two options: You can/ cannot save,what you see.

Remote Guidance> Guide through it: You will guide me through the information,

which is on my (and also your) screen.Application Sharing

> Joint work: Both parties work on one file simultaneously.Both parties are able to modify the file.

Bundling with other applications> Multi-Service Bundling: Look on it!

Work on it!Talk about it!


You told me, how easy it is to make a reservation via mobile.But I can’t make it: You guide me through the service –Remotely, because you are not in Cannes right now.

You would like to get a feedback from a colleague in the office. Show him your slides!

Jointly looking at your slides, you can discuss which aspects you could change.bundled with

voice application

‘Just take a look on the last email I have received …’

‘OK, I will show you a photo of my new baby born. Let’s have a look at my screen …’


Conclusions for IMS

Todays mobile networks lack some functionalities

This gap is filled by IMS

IMS provides a 3GPP standardised infrastructure for an efficient deployment of numerous multimedia services

IMS enables peer2peer communication in the ps domain

IMS provides an efficient multimedia oriented session control

IMS keeps the value chain within operator’s network

IMS comes with an state-of-the-art service creation concept

IMS leverages the process of finding the UMTS killer application

One IMS client supports all IMS services
