11/04/23 Abderrahim Benslimane: Réseaux Mobiles ( GSM, 2G 3G) 21
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.
11/04/23 Abderrahim Benslimane: Réseaux Mobiles ( GSM, 2G 3G) 22
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.
11/04/23 Abderrahim Benslimane: Réseaux Mobiles ( GSM, 2G 3G) 23
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

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
11/04/23 Abderrahim Benslimane: Réseaux Mobiles ( GSM, 2G 3G) 32
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.

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
11/04/23 Abderrahim Benslimane: Réseaux Mobiles ( GSM, 2G 3G) 42
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.
11/04/23 Abderrahim Benslimane: Réseaux Mobiles ( GSM, 2G 3G) 43
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)

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

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
