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)
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.
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.
