Macro Cellules Zones à population dispersée ( diamètre: 10-30km) Usage: voiture, train, etc….

Micro Cellules Zones à population très denses ( 100 à 300m); Usage: piétons L’utilisation de petites cellules permet l’optimisation des canaux de

transmission et une meilleure précision dans la localisation.

Pico Cellules Réservé aujourd’hui aux réseaux de proximité ( > 10m) Concept repris dans l’UMTS

Cellules sélectives Les cellules n’ont pas toujours besoin d’une couverture de 360 degrés

Cellules « parapluie » Pour éviter un nombre trop important de commutations entre cellules, il est

possible de créer des regroupements de cellules.


Couverture Cellulaire


Handover et Roaming

HandoverMécanisme permettant le transfert automatique d’une transaction en

cours d’une cellule vers une cellule, sans perturber la communication.

Protocole utilisé: LAPDm

•Interface Abis Gère les communications entre BTS et BSC, en

particulier: La gestion du trafic radio L’exploitation et la maintenance des stations BTS Protocole utilisé: LAPD

•Interface A Gère les communications entre BSC et MSC, en

particulier le handover Signalisation du type SS7 Protocole utilisé: BSSAP


2G: Interface Radio GSM

Le spectre radio a des ressources limitées, partagées entre tous les utilisateurs. La méthodologie de partage de bande-passante est une combinaison entre multiplexage temporel et multiplexage fréquentiel (TDMA/FDMA).

FDMA utilise 124 fréquences de transmission dans la bande des 25 MHz. A chaque station de base (BS) sont associées une ou plusieurs fréquences.

Dans TDMA chaque fréquence de transmission est découpée canaux logiques.


2G: Le protocole BSSAP

The MTP and the SCCP are used to support signaling messages between the Mobile Services Switching Center (MSC) and the Base Station System (BSS).

One user function of the SCCP, called BSS Application Part (BSSAP) is defined.

The BSSAP user function is further subdivided into two separate functions: The Direct Transfer Application sub-Part (DTAP), also called GSM L3, is

used to transfer messages between the MSC and the MS (Mobile Station) The BSS Management Application sub-Part (BSSMAP) supports other

procedures between the MSC and the BSS related to the MS (resource management, handover control), or to a cell within the BSS, or to the whole BSS.


2G GSM MAP Protocols

The equipment in the mobile network subsystem exchange signaling information through the Mobile Application Part (MAP), which is built on top of SS7.

MAP supports: MAP and SMS capabilities for IS-41 and GSM

networks Acting as the VLR, HLR, and MSC MAP-GSM acting as the VLR, HLR, MSC, and

SGSN/GGSN Implementing GSM Phase 1, Phase 2, and

Phase 2+. It also supports MAP-GSM extensions for GPRS and CAMEL

2G to 3G Evolutions (3)


2,5G : GPRS Key User features

The General Packet Radio Service (GPRS) is a new nonvoice value added service that allows information to be sent and received across a mobile telephone network. SPEED:

Theoretical maximum speeds of up to 171.2 kbps

IMMEDIACY: GPRS facilitates instant connections whereby information can be sent or

received immediately as the need arises, subject to radio coverage. This is why GPRS users are sometimes referred to be as being "always connected".

NEW APPLICATIONS, BETTER APPLICATIONS: GPRS facilitates several new data-oriented applications

SERVICE ACCESS: To use GPRS, users specifically need:a mobile phone or terminal that supports GPRS a subscription to a mobile telephone network that supports GPRS


2,5G : GPRS Key Network features

PACKET SWITCHING GPRS involves overlaying a packet based air interface on the existing circuit

switched GSM network. This gives the user an option to use a packet-based data service.

SPECTRUM EFFICIENCY Packet switching means that GPRS radio resources are used only when users

are actually sending or receiving data.

INTERNET AWARE GPRS fully enables Mobile Internet functionality by allowing interworking

between the existing Internet and the new GPRS network..

SUPPORTS TDMA AND GSM GPRS is not only a service designed to be deployed on the GSM digital mobile

phone standard. The IS-136 Time Division Multiple Access (TDMA) standard, popular in North and South America, will also support GPRS.

3G: New mobile terminals


The (US) CDMA revolution

Traditionally radio communication systems have separated users by either frequency channels, time slots, or both. More recently several hybrid FDMA-TDMA digital systems have been developed, ostensibly to enhance service quality and capacity. In all these systems, each user is assigned a particular time-frequency slot.

CDMA offers an answer to the capacity problem. Instead of partitioning either spectrum or time into disjoint "slots" each user is assigned a different instance of the noise carrier.

The great attraction of CDMA technology from the beginning has been the promise of extraordinary capacity increase over narrowband multiple access wireless technologies


CDMA vs. GSM (1)

For several years, the world's two main methods -- Code-Division Multiple Access (CDMA) and GSM have divided the wireless world into opposing camps.

CDMA: popular in US, more than 80M users.Advantages of CDMA include:

Increased cellular communications security. Simultaneous conversations. Increased efficiency, meaning that the carrier can serve more subscribers. Smaller phones. Low power requirements and little cell-to-cell coordination Extended reach - beneficial to rural users situated far from cells.

Disadvantages of CDMA include: CDMA is relatively new, and the network is not as mature as GSM. CDMA cannot offer international roaming, a large GSM advantage.


CDMA vs. GSM (2)

Advantages of GSM: International roaming permits subscribers to use one phone throughout

Western Europe. GSM is mature, having started in the mid-80s. This maturity means a more

stable network with robust features. CDMA is still building its network. The availability of Subscriber Identity Modules, which are « smart cards »

that provide secure data encryption give GSM m-commerce advantages.

GSM still holds the upper hand however. There's the numerical advantage for one thing: 456 million GSM users

versus CDMA's 82 million

But…. The proposed IMT-2000 standard for 3G globally is a worldwide CDMA-based standard (WCDMA)

SMS key functions

SMS Advantages « Store and Forward »: messages are registerd even if the destination is

not on on-line SMS messages are handled by the SMS-C and not by network switching SMS messges are transmitted without establishment of voice trunks

(SS7-based messaging) SMS messges are secured: receiption acknowledge (SS7 procedure)

SMS Disadvantages Limited message length ( 140 octets remaining, excluding MAP signaling

part) Fixed message structure Signaling channels performance is limited.


Next Generation Messaging (1): SMS EMS

EMS = Enhanced Messaging ServiceGeneration of combined melodies, sounds, images, animations, modified & formatted texts…

Images: 3 formats, black and whiteSounds: 10 predefined soundsSMSs aggregation

As for SMS, based on SS7 and managed by the SMS-Centres

2G application, but needs « EMS-like » terminals

Available early in 2001, as an evolution of Nokia’s « Picture Messaging »


Next Generation Messaging (2): SMS MMS

MMS = Multimedia Messaging ServiceGeneration of messages combining text, sound & images (Power-Point like), photos & videos. To be standardized by 3G Study Groups, will really start with GPRS and become popular with UMTSMMS will use dedicated channels (voice trunks), based on WAP

Available in 2003 – 2004 ? (Ericsson et Nokia have started to launch products in 2001)

The SMS MMS revolution will be like the transition from DOS Windows


Some « Flash » statistics !!! (August 2001)

More than 50 Billion SMS’s exchanged worldwide durint Q1 2001 !

9 Billion messages per month in 2000, more than 6 billion in Europe…

15 Billion messages only in december 2000Approx. 1O Million SMS-s per day in France ( +42%)

420 million mobile handsets sold worldwide in year 2000 …

This progression is planned to go on until 2005 ….


WAPWAP+ =Mobile TelephonyInternet

WAP Services: Internet / Mobile convergence

WAP = Wireless Application Protocol

WAP is based on Client/Server architectures


What is WAP ?

The wireless industry came up with the idea of WAP. The point of this standard was to show internet contents on wireless clients, like mobile phones.

WAP stands for Wireless Application Protocol WAP is an application communication protocol WAP is used to access services and information WAP is inherited from Internet standards WAP is for handheld devices such as mobile phones WAP is a protocol designed for micro browsers WAP enables the creating of web applications for mobile devices. WAP uses the mark-up language WML (not HTML) WML is defined as an XML 1.0 application


WAP Architecture

HTTP ServerWAP Server

WAP Gateway

WAP Terminal

INTERNETThe architecture is based on the Internet model:

- the wireless WAP terminal contains a microbrowser,

- content and applications are hosted on Web (HTTP/WAP)servers.

WAP pre-requisite: « Mark-Up » Languages

Definition:Mark-Up Languages are used on the web to isolate the display

style from the content of a document

Types:HTML = Hypertext mark-up language (controls the formatting of a

document), written in JavaScriptXML = Extensible mark-up language (marks sections of the data

as objects that can be managed by associated databases)HDML = Handheld device mark-up language (proprietary

technique)WML = Wireless mark-up language (XML adapted for WAP

technology and mobile handsets), written in WMLScript.


The future of WAP

Le WAP is to-day in competition with the japanese standard I-MODE (more than 24 Million subscribers)WAP will survive, assuming that:

GPRS deployed (enhanced bitrates, client-server mode)Enhancement of handsets ergonomyDevelopment of combined SMS – WAP applications

To-day: Wait And Pay … … To-morrow: Win And Play
