INTRODUCTION FOR GSM

GSM IS GLOBALLY ACCEPTEDSTANDARD FOR DIGITAL CELLULAR

COMMUNICATION. GSM IS THE NAMEOF THE STANDRDIZATION GROUPESTABLISHED IN 1982 TO CREATE ACOMMON EUROPEAN MOBILETELEPHONE STANDARD THAT WOULD

THE EVOLUTION OF MOBILE

TELEPHONE SYSTEMS CELLULAR IS ONE OF THE

FASTEST GROWING AND MOSTDEMANDING TELECOMMUNICATION

APPLICATIONS. TODAY, IT REPRASENTS A

CONTINOUSLY INCRESAINGPERCENTAGE OF NEW TELEPHONESUBSCRIPTIONS AROUND THE

WORLD. CURRENTLY THEY ARE MORE THAN

45% MILLION SUBSCRIBERS WORLDWIDE,

AND 50% OT THOSE SUBSCRIBESARE LOCATED IN UNITED STATES.

USING CELLULAR SYSTEMS IS ADIGITAL TECHNOLOGY WILL

BECOME THE UNIVERSLMETHOD OF TELECOMMUNICATIONS.

BY THE YEAR 2005 THERE WILL BEMORE THAN 100 MILLIONCELLULAR SUBSCRIBESWORLDWIDE.

GSM MILESTONES THE IDEA OF CELL-BASED MOBILE

RADIO SERVICE WAS FORMULATED INTHE UNITED STATES AT THE BELLLABS IN THE EARLY 1970S.

HOWEVER, THE NORDIC COUNTRIESWERE THE FIRST TO INTRODUCE

CELLULAR SERVICES FOR COMMERCIALUSE WITH THE INTRODUCTION OF THENORDIC MOBILE TELEPHONESERVICES(NMT) IN 1981.

CELLULAR SYSTEM BEGAN IN THEUNITED STATES WITH THE REALESE OFTHE ADVANCED MOBILE PHONESERVICES(AMPS) IN 1983.

THE AMPS STANDARD WASADOPTED BY THE AISA, LATIN

AMERICA, AND OCEANICCOUNTRIES, CREATING THELARGEST POTENTIAL MARKETIN THE WORLD FOR

CELLULAR.FROM 1982-1985 AFTER MULTIPLE

TESTS A DIGITAL SYSTEM WASADOPTED FOR GSM.

IN 1987 THE TIME DIVISIONMULTIPLE ACCESSES (TDMS)

SOLUTION WAS CHOOSEN.

WHY HAS SM N SUCCESSFUL

THE SUCCESS OF GSM IS THAT ITSDEVELOPMENT WAS FOUNDED ON THEDELIVERY OF A SPECIFIC USERBENEFIT-INTERNATIONAL ROAMING.

THE USE OF VERY LARGEINTEGRATION(VLSI) TECHNOLOGY ANDOTHER LOW COST IC ARCHITECTURESPAVED THE WAY FOR MORE EFFICENTAND AFFORDABLE POCKET-SIZEDMOBILE PHONES.

WITHOUT GSM THE PACE OF

DEVELOPMENT OF MOBILE TELEPHONYWOULD HAVE PARED DRAMATICALLYAND THE ADDITIONAL STREAMS, SUCHAS ROAMING WOULD NOT HAVE BEENAS SUCCESSFUL.

THE SM NETWORK

THE GSM NETWORK DIVIDED INTOTHREE MAJOR SYSTEM.

(1) SWITCHING SYSTEM

(2) BASE STATION SYSTEM

(3) OPERATION AND SUPPORTSYSTEM

SEMINOR TITLE: GSM COMMUNICATIONS DATE:29-01-2010

(1) SWITCHING SYSTEM-

THE SWITCHING SYSTEM ISRESPONSIBLE FOR PERFORMINGCALL PROCESSING SUBSCRIBERSRELATED FUNCTIONS.

(2) BASE STATION SYSTEM-

THE BSS PERFORMS ALL RADIO-RELATED FUNTIONS.

(3) OPERATION AND SUPPORT SYSTEM-

THE PURPOSE OF OSS IS TO OFFERTHE CUSTOMER COST-EFFECTIVE FORCENTRALISED , REGIONAL THAT AREREQUIRED FOR A GSM NETWORK.

GSMSUBSCRIBERSSERVICES

THERE ARE TWO BASIC TYPES OF

SERVICES IN GSM.(1)TELEPHONY-

THESE SERVICES ARE MAINLY VOICESERVICES THAT PROVIDE SUBSCRIBES

WITH THE COMPLETE CAPABILITY TOCOMMUNICATE WITH OTHER SUBSCRIBERS.

(2)DATA-

THESE SERVICES ARE MAINLY PROVIDETHE CAPACITY NECESSARY TO TRANSMITAPPROPRIATE DATA SIGNALS BETWEENTWO ACCESS.

GSM ECONOMIC IMPACT

IT IS ESTIMATED THAT GLOBALSUBSCRIBERS WILL EXCEED 1.5 BILLION IN2004 AND REACHED 2.3 BILLION BY 2010

AND EXCEPTIONS ARE THAT ATLEAST 85%OF THE WORLDS NEXT GENERATIONWIRELESS CUSTOMERS UTALISE THE GSM

FAMILY OF TECHNOLOGIES FOR BOTHVOICE AND DATA SERVICES. IN 2003 THE REVENUE OF GSM MOBILE

NETWORK IS $426BILLIONS. THE MOBILE TELEPHONY HAS CREATED 4.1

MILLION JOBS WORLDWIDE WITHIN THISGSM. EXCEPTING THE INDUSTRY TO REACH

10MILLION JOBS BY 2010.
