CHAPTER-1 INTRODUCTION 1.1 OVERVIEW Due to the betterment and enhancement of technology

Mobile services are all services that can be used independently of temporal and spatial restraints, and that are accessed through mobile devices (Heinonen & Pura, 2006). Mobile devices can be classified into five categories, these are communication services such as SMS, MMS video calls and mobile emails, entertainment services which include games, mobile TV and music,

In the first chapter of “Technology: A World History” it discusses the first technologies early humans use of tools beginning with cobbles. As tools developed it changed the lives of these early humans. The ever changing technology helped them create more complex tools for hunting, gathering food, protection, erecting shelters, preparing meat for cooking and eating. It allowed them to move around to colder climates. When they went from foraging to farming and eventually settle into one place, which led to the creation of larger more complex tool, textiles replacing animal skin by developing looms that could take fibers that was used to make cloth. Technology although simple in our standards continued to rapidly evolve.

First of all, customer criticized that their phone or SIM card had problems. When many people used for a long time, the network and text messages will be affected badly. The solution is that internal flaws needs improvements.

The country’s major telecommunications companies have reported a resurgence in the volume of text messages sent over their networks in the year 2011,

The use of short-messaging systems (SMS) is becoming more mainstream due to the exponential increase in cell phone usage and other mobile devices. From messages sent through Twitter to emergency notifications broadcast through mobile networks, the short-messaging systems is becoming more ubiquitous.

Instant messaging (IM) is a rapid and on the rise communications medium trendy with both company and home users. From its commencement as easy peer-to-peer conversation service, instant messaging has developed to grow to be a staple mode of contact for millions of internet users. Once restricted to desktops, accepted instantaneous messaging services IM has found its means into handheld gadgets and cell phones, permitting users to communicate from virtually anywhere.

People have become more and more comfortable and confident in digital communications solutions, including mobile phone. In fact, there are now more subscribers in the mobile phone service in the world (2.4 million), and there are mobile subscribers to fixed lines. Mobile phone has become the basic communication means, not only for voice but also for digital services, and e-mail, digital photos, navigation, etc. all over the world more than 350 million text messages, also known as "SMS messages" are exchanged worldwide mobile networks each month.

Mobile Technology is getting advanced day by day and so are their applications. With the increase in technology of mobile platform and their new applications, people are getting more diverge and involved in it. Not only the normal person, developers of the mobile application are developing new application and new version of older application which are compatible with today’s new mobile platforms. In today’s era, everyone is carrying a mobile phone as one of the necessary thing. Social networking websites like Facebook and Twitter have fascinated masses to update their day to day activity. Mobile phones are satisfying the need of pocketbook and notecases for people. Media is also playing a great role in promoting and attracting large crowd to use different applications on their mobile phones [2]. Using mobile applications, anyone can see the latest news (regarding global, economical, weather, international, sports) or update of the things going around the world from anywhere. Mobile application can be used in every

The invention of the text message was developed in 1984 by the GSM Corporation two inventors named Friedhelm Hillebrand and Bernard Ghillebaert; the two created a way to send a short message using existing cellular signals (Yukozimo). The signals are sent and received from a cell phone tower or control channel. In order for the phone calls and messages to come through, the control channel needs to know which phone belongs to which phone number. Depending on the location of the cell phone, it will

Abstract-With the rapid development of digital technology in consumer electronics, advertising and notification system has greater importance. Earlier systems had the drawback that the notice board or systems that were to display notice has been done manually. The idea proposed to this project is that using GSM technology so that the updates could be made with mobile and check for the authority in the system. So updates to these notice boards could be made through a simple SMS. The importance of notice in academic is well known to us but this system could be not only in the school or educational but also for commercial purposes such as advertising or emergency notification system.

Messaging is referred to as a real time text based communication that has two main forms: Instant messaging and text messaging. Instant messaging is most commonly used on computers but are extremely popular on cell phones as well. Mobile phone clients can get instant messaging through application programming downloaded to their telephones and get instant messages simply like they would on the off chance that they were on their PC. Extraordinary sample of this is Facebook. With the popularity of social media (Facebook) we can receive up to date instant messages via cell phone through the instant message applications and stay up to date with friends and family. Another form of messaging is text messaging. Text messaging is a method of person to person communication in which user’s type short text messages from mobile phones. Text messaging uses the Short Message Service

The mobile penetration levels have been constantly growing in developed markets, the use of the SMS as a communication method has been widely accepted, the

Abstract— This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller AT89c52 at the heart of the system. The microcontroller is interfaced with GSM Modem via MAX232 level convertor. It is used to convert RS232 voltage levels to TTL voltage levels and vice versa. The hardware also has a 64K EEPROM chip AT24C64. This EEPROM is used to store the timings and messages to be displayed. Hardware also contains a real time clock DS1307 to maintain track of time. A 16x2 Character LCD display is

As the GSM uses the combination of Time and FDM, the mobile is used to demultiplex the given channel and also it is responsible for accessing the channel more effectively and efficiently. The mobile device is used to transmit and receive the required data within in a given time frame and with if a give condition. With the help of mobile devices, there are many other services offered by the GSM to enable ad to support more efficient data transmission. These services can be SMS, MMS etc. All these services can only be accessed with the help of mobile devices which supports may other multimedia features like live calling, video calling etc. Every day,

Abstract: It is time consuming task for parents to check the regular presence of the children in the school. But this project of sending information to the parents whose children were absent from the school through GSM in the form of SMS will give an easy, low cost and automatic solution. This project presents a system to monitor pickup of school children to enhance the safety of children during the daily transportation to school. The system consists of two main units, a bus unit and a school unit. The bus unit system is used to detect when a child boards the bus. This information is communicated to the school unit that identifies which of the children did not board the bus and issues an alert message accordingly. The system has a developed PC-based database-driven application that facilities its management and provides useful information about the children to authorized personal. A complete prototype of the proposed system was implemented and tested to validate the system functionality. The results show that the system is promising for daily transportation safety. The technology implemented here is aimed to detect the presence of a particular student who enters into the school bus and by sensing the presence of student, this information is passed to the school from where the absent students information is sent to the student parent’s mobile through GSM. This entire information is stored in the computer simultaneously.
