Objectives: ☺ Types of Services ☺ Value Added Services ☺ Location Based Services ☺ Innovative Features

GSM Services Ø Services are defined as anything the end user explicitly sees as worth paying for. Ø The primary objective of a mobile telephony system is to allow mobile subscribers to communicate effectively.

SERVICE CATEGORIES Main type of telecommunication services: ☻ Basic services: Available to all subscribers to a mobile network. e. g. voice telephone calls. ☻ Supplementary services: Additional services that are available by subscription only. e. g. Call forwarding.

Basic Telecommunication Services Teleservice allows the subscriber to communicate (usually via voice, fax, data or SMS) with another subscriber. It is a complete system including necessary terminal equipment.

Basic Telecommunication Services Bearer services It transports speech and data as digital information within the network between user interfaces. e. g. - a bearer service associated with the speech telephony teleservice is the timeslot assigned to a call on a TDMA frame over the air interface.

TELESERVICES Emergency calls The emergency call function enables a subscriber to make an emergency call by pressing a predefined button or by using the emergency number. (like 112 , 911).

TELESERVICES SMS Cell Broadcast (SMSCB) A text message with a maximum length of 93 characters can be broadcast to all mobiles within a certain geographic area. traffic congestion warnings accident reports, weather announcements and advertisements.

TELESERVICES Voice mail This service is an answering machine within the network that is controlled by the subscriber. The subscriber accesses the mail box using a personal security code.

SUPPLEMENTARY SERVICES ☺ Call Forwarding ☺ Call Barring (Outgoing) ☺ Call Barring (Incoming) ☺ Call Waiting ☺ Call Hold

SUPPLEMENTARY SERVICES Barring of outgoing calls The subscriber can activate or deactivate this service from the MS with a variety of options for barring outgoing calls. • Bar all outgoing calls • Bar all outgoing international calls except those directed to the home PLMN. ** barring password required **

SUPPLEMENTARY SERVICES Barring of incoming calls This is desirable because in some cases the called mobile subscriber is charged for parts of an incoming call (during international roaming) • Barring of all incoming calls • Barring of incoming calls when outside home PLMN ** barring password required **

SUPPLEMENTARY SERVICES Call waiting • • • This service notifies the mobile subscriber, usually by an audible tone, for incoming call. The incoming call can be any type of basic service including speech, data or fax. There is no notification in the case of an emergency call or SMS. ** to activate call waiting dial *43#

SUPPLEMENTARY SERVICES Call hold This supplementary service enables the subscribers to put the basic normal telephony service on hold in order to set up a new call or accept a waiting call.

SUPPLEMENTARY SERVICES Calling line identification services: These cover both the presentation and restriction of the calling line identity. The presentation part of the service supplies the called party with the ISDN or MSISDN number of the calling party. The restriction service enables calling parties to restrict the presentation of their number on the MSs of called parties

SUPPLEMENTARY SERVICES Closed User Group (CUG) The CUG service enables subscriber connected to the PLMN/ISDN and possibly other networks, to form groups in which access is restricted. Example: members of a specific CUG can communicate with each other, but generally not with users outside the group.

INNOVATIVE FEATURES Regional and local subscription These features allow subscribers to subscribe to a service in a specified geographical area. Requests for service outside the area are rejected with the exception of emergency calls and SMS. For local subscriptions, the geographical area consists of a number of cells, and for regional subscription, the area consists of LAs.

Mobile Applications

Mobile Messaging Ø SMS Ø EMS Ø MMS Ø Instant Messaging Ø Streaming

Short Message Services (SMS) The service allows simple text message consisting of a maximum of 160 alphanumeric characters to be sent to or from an MS. If the MS is switched off, or has left the coverage area, the message is stores in a Short Message Service Center (SMS -C). When the mobile is switched on again or has re-entered the network coverage area, the subscriber is informed that there is a message.

Enhanced Messaging System (EMS) • EMS can support relatively simple pictures, sounds and animation. • EMS messages that are sent to devices that do not support it will be displayed as SMS transmissions. • It is a 3 GPP standard.

MULTIMEDIA MESSAGE SERVICE (MMS) • MMS means a multimedia presentation which consists of music, voice, image, text, video and graphics all synchronized across a common timeline. • “Synchronized Power Point Presentations”.

MULTIMEDIA MESSAGE SERVICE (MMS) • MMS-enabled mobile phones enable subscribers to compose and send messages with one or more multimedia parts. Mobile phones with built-in or attached cameras, or with built-in MP 3 players are very likely to also have an MMS messaging client -- a software program that interacts with the mobile subscriber to compose, address, send, receive, and view MMS messages.

Instant Messaging It enables to communicate with another individual in real time, analogous to a telephone conversation but using text based communication instead of voice-based communication.

Streaming • It enables real time or on demand distribution of audio, video and multimedia on the internet. • It is simultaneous transfer of digital media (video, voice and data) so that it is received as a continuous real-time stream.

Location Based Applications

Location Based Applications In this age of significant telecommunications competition, mobile network operators continuously seek new and innovative ways to create differentiation and increase profits. One of the best ways to do accomplish this is through the delivery of highly personalized services. One of the most powerful ways to personalize mobile services is based on location.

Positioning One of the most obvious technologies behind LBS is positioning, with the most widely recognized system being the Global Positioning System (GPS). There are however, other means of positioning in addition to GPS. These other technologies are network based positioning and typically rely on various means of triangulation of the signal from cell sites serving a mobile phone. In addition, the serving cell site can be used as a fix for location of the user.

Geographic Information Systems Geographic data is an important aspect of any location system. Geographic Information Systems (GIS) provide the tools to provision and administer base map data such as man made structures (streets, buildings) and terrain (mountains, rivers). GIS is also used to manage point-of-interest data such as location of gas stations, restaurants, nightclubs, etc. Finally, GIS information also includes information about the radio frequency characteristics of the mobile network. This allows the system to determine the serving cell site of the user.

Traffic Information APPLICATION OVERVIEW This service both collects and distributes traffic information. Traffic information is very important need for city dwellers. Systems can estimate traffic information by sampling mobiles in automobiles on freeways anonymously to determine average velocity of vehicles. If this is not possible in locataion more static information can be collected from city authorities. All this information is mapped and sent to mobile users who request it. • Stickiness : Daily traffic info. pushed during rush hours via SMS/MMS • Most people need to know the current traffic sitution on their route. • Hosting: Operator / ISP • WAP/Web/MMS/SMS: yes/yes/yes • Devices supported: - All devices • Commerically used worldwide

Push-To-Talk (PTT) is a two-way communication service that works like a "walkie talkie". A normal cell phone call is full-duplex, meaning both parties can hear each other at the same time. PTT is half-duplex, meaning communication can only travel in one direction at any given moment. To control which person can speak and be heard, PTT requires the person speaking to press a button while talking and then release it when they are done. The listener then presses their button to respond. This way the system knows which direction the signal should be traveling in.

Push-To-Talk over cellular (Po. C) The Motorola, Nokia, Ericsson, Siemens, Huawei, Mobile Tornado, Wireless ZT, etc. versions of PTT are based on 2. 5 G or 3 G packet-switched networks and use SIP and RTP protocols. These particular versions of PTT are called "Push to Talk over Cellular", which is abbreviated "Po. C". ** Session Initiation Protocol (SIP) Real-Time Transport Protocol (RTP)
