• Barring of all incoming calls• Barring of incoming calls when outside home PLMN

** barring password required **

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.

SUPPLEMENTARY SERVICES

SUPPLEMENTARY SERVICES

Call holdThis 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.

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.

SUPPLEMENTARY SERVICES

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.

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 3GPP standard.

• 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 MP3 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.

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.

Location Based Applications

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.

Positioning

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.

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.

Push-To-Talk (PTT)

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 (PoC)

The Motorola, Nokia, Ericsson, Siemens, Huawei, Mobile Tornado, Wireless ZT, etc. versions of PTT are based on 2.5G or 3G packet-switched networks and use SIP and RTP protocols. These particular versions of PTT are called "Push to Talk over Cellular", which is abbreviated "PoC".
