ABSTRACT

A unique marketing tool for telecom and wireless hardware, software and services

vendors for leads generation, and a unique gift to their partners and customers. A

comprehensive wireless communication technology guide for network and telecom

professionals. An easy to use training reference for telecom and wireless technology students

to get an overall picture of WLAN, WPAN, WMAN, WWAN and Mobile technologies.

There are many features associated with GSM technology due to which it is bar far the most

leading mobile communication technology in the world today.

GSM technology facilitates with high speed integrated data, voice data, fax,

mail, voice mail and mostly used SMS feature. This supports varied frequency. One of the

major advantages of GSM technology which changed the way we looked mobile phones at

the beginning. GSM actually brought the concept of being Mobile way beyond the limits. It

enabled us to communicate across the continents. GSM phone deliver very good voice

quality, support useful services and standards, it is very likely that GSM will remain the only

mobile communication network technology to be adopted by each and every country of the

world.

This proposed project will manages students information (such as their IA

averages, Attendance, Events) and sends it to their parents mobile as per the scheduled dates

set by the authority. Similarly parents can also request for students information by sending

their request to the service number .And this software provide them with their intended

information they requested with minimal time period.

Chapter 1

INTRODUCTION

The project basically works by sending students information such as IA marks

average, their attendance and events in college to their parents or guardians as specified in

database of college using GSM modem .It also has scheduling functions that take care of

sending students information automatically as per the scheduled dates. Thus it provides

flexibility by allowing the members to only enter the students information within specified

dates and rest of work is taken care by the software automatically without any human

interaction.

As GSM modem works only using AT commands whatever students

information needs to be sent is passed to modem using AT commands and thus information

is sent to the intended persons.

If any parents want to know about any information about their childrens then

they will send their request to messing service number .This message will be stored in anappropriate form, which then can be checked by authorized persons and can reply to intended

person.

2.2 Technologies used

Introduction to .NET

2.2.1 .NET Framework

.NET is Software platform. It is a language neutral environment for development

rich. .NET experiences and application that can easily and securely operated within it.When

development application are developed these application will target .NET and execute where

.NET is implemented instead of targeting a particular hardware /OS combination. The

components that make up the .NET platform are collectively called the .NET framework.

The .NET framework is managed, type safe environment for development and

executing application the .NET framework manages all aspect of program execution like

allocation of memory for the storage of data and instruction, granting and denying permission

to the application, managing execution of the application and reallocation of memory for the

resource that are not needed.

The .NET framework is designed for cross language compatibility. Cross language

compatibility means, an application written in Visual Basic .NET may reference a DLL file

written in C#(C-Sharp).A Visual Basic .NET class might be derived from a C# class or vice

versa.

2.2.2 Components Of .NET Framework

1. Common Language Runtime (CLR)

2. Class Libraries

3. Common Language Specification (CLS)


13/69


TECHNOLOGY



1) Common Language Runtime (CLR)

The CLR is described as the execution engine of .NET .It provides the

environment within which the programs run. Its this CLR that ma nages the execution of

programs that provides core services, such as code compilation, memory allocation, thread

management and garbage collection through the common type system (CTS).

It enforces strict type safety and it ensure that the code is executed in safe environment

by enforcing code access security .The software version of .NET is actually the CLR version.

2) Class Libraries

Class library is the second major entity of the .NET Framework which is designed to

integrate with the common language runtime. This library gives the program access to

runtime environment. The class library consist of lots of prewritten code that all the element

like forms, controls and rest in VB .NET and Visual Studio .NET application actually comes

from the class library.

3) Common Language Specification (CLS)

If we want the code which we write in language to be used by program in other

language then it should adhere to the Common Language Specification (CLS).The CLS

describes a set of features that different languages have in common. The CLS define the

minimum standards that .NET language compilers must conform to, and ensure that any

source code compiled by .NET compiler can interoperate with the .NET Framework.

Some reasons why developers are building applications using the .NET Framework:

Improved Reliability

Increased Performance

Developers Productivity


14/69


TECHNOLOGY



Powerful Security

Integration with existing system

Ease of Development

Mobility Support

XML WEB service support

Support for over 20 Programming languages

Flexible data access

2.2.3 .NET vs. Java

Many of us wonder what .NET has done with java. Is there any relation between

them? Are they similar? And so on. I even hear some people say .NET is Microsoftsanswer

to java. I thinkevery language has its own pros and cons. Java doesnt have a visual interface

and requires us to write heaps of code to develop applications. On the other hand, with .NET,

the framework supports around 20 different programming languages which are better and

focus only on business logic leaving all other aspects of the framework. Visual Studio .NET

comes with rich visual interface and supports drag and drop .Many applications were

developed, tested and maintained to compare the difference between .NET and Java and the

end result was particular application developed using .NET requires less line of code ,less

time to develop and lower development cost along with other important issues. Personally, I

dont mean to say that java is a gone or .NET based applicat ion are going to dominate the

internet but I think .NET definitely has an extra edge as it is packed with features that simply

application development.

SIM card interface

You can use AT Command to get information in SIM card.The SIM interface

supports the functionality of the GSM Phase 1 specification and also supports the

functionality of the new GSM Phase 2+ specification for FAST 64 kbps SIM(intended for

use with a SIM application Tool-kit).Both 1.8V and 3.0V SIM Cards are supported. The SIM

interface is powered from an internal regulator in the module having nominal voltage 2.8V.

All pins reset as outputs driving low. Logic levels are as described in table

2.3 AT Commands

A series of machine instructions used to activate features on an intelligent modem.

Developed by Hayes Microcomputer Products and officially known as the Hayes Standard

AT Command Set, it is used entirely or partially by most every modem manufacturer. AT is a

mnemonic code for ATtention, which is the prefix that initiates each command to the

modem.

2.3.1 AT Command syntax

The "AT" or "at" prefix must be set at the beginning of each command line. To

terminate a command line enter .Commands are usually followed by a response that

includes.Throughout this document, only the responses

TECHNOLOGY



are presented, are omitted intentionally. The AT command set implemented by

SIM300 is a combination of GSM07.05, GSM07.07 and ITU-T recommendation V.25ter and

the AT commands developed by SIMCOM.

Note: Only enter AT command through serial port after SIM300 is power on and

Unsolicited Result Code RDY is received from serial port. And if unsolicited result

codeSCKS: 0 returned it indicates SIM card isnt present. If autobaudi ng is enabled,

the Unsolicited Result Codes RDY and so on are not indicated when you start up the

ME All these AT commands can be split into three categories syntactically: basic, S

parameter, and extended. These are as follows:

2.3.2 Basic syntax

These AT commands have the format of AT, or AT&, where

is the command, and is/are the argument(s) for that command. An example of

this is ATE, which tells the DCE whether received characters should be echoed back

to the DTE according to the value of . is optional and a default will be used if

missing.

2.3.3 S parameter syntax

These AT commands have the format of ATS=, where is the index

of the S register to set, and is the value to assign to it. is optional; if it is

missing, then a default value is assigned.

2.4 Database Used

2.4.1 Introduction to Microsoft Office Access 2010

Microsoft Access is a computer application used to create and manage computer-

based databases on desktop computers and/or on connected computers (a network). Microsoft


20/69


TECHNOLOGY



Access can be used for personal information management (PIM), in a small business to

organize and manage data, or in an enterprise to communicate with servers.

Microsoft Access (MS Access) enables one to manage all important information from

a single database file. Within the file, one can use:

Tables to store your data.

Queries to find and retrieve specific data of interest.

Forms to view, add, and update data in tables.

Reports to analyze or print data in a specific layout.

Data access pages to view or update, the data.

In MS Access, data is stored once in one table, but can be viewed from multiple

locations. When the data is updated in a Table, Query or Form, it is automatically updated

everywhere it appears.

2.4.2 Features Microsoft Office Access 2010

Users can create tables, queries, forms and reports, and connect them together

with macros. Advanced users can use VBA to write rich solutions with advanced data

manipulation and user control.

The original concept of Access was for end users to be able to "access" data from any

source. Other uses include: the import and export of data to many formats including Excel,

Outlook, ASCII, dBase, Paradox, FoxPro, SQL Server, Oracle, ODBC, etc. It also has the

ability to link to data in its existing location and use it for viewing, querying, editing, and

reporting. This allows the existing data to change and the Access platform to always use the

latest data. It can perform heterogeneous joins between data sets stored across different

platforms. Access is often used by people downloading data from enterprise level databases

for manipulation, analysis, and reporting locally.

One of the benefits of Access from a programmer's perspective is its relative

compatibility with SQL (structured query language) queries can be viewed graphically or

edited as SQL statements, and SQL statements can be used directly in Macros and VBA

Modules to manipulate Access tables. Users can mix and use both VBA and "Macros" for

programming forms and logic and offers object-oriented possibilities. VBA can also be

included in queries.

Microsoft Access offers parameterized queries. These queries and Access tables can

be referenced from other programs like VB6 and .NET through DAO or ADO. From

Microsoft Access, VBA can reference parameterized stored procedures via ADO.

Microsoft Access is a file server-based database. Unlike clientserver relational

database management systems (RDBMS), Microsoft Access does not implement database

triggers, stored procedures, or transaction logging. Access 2010 includes table-level triggers

and stored procedures built into the ACE data engine. Thus a Client-server database system

is not a requirement for using stored procedures or table triggers with Access 2010. Tables,

queries, Forms, reports and Macros can now be developed specifically for web base

application in Access 2010. Integration with Microsoft SharePoint 2010 is also highly

improved.[5]

TESTING, VERIFICATION AND VALIDATION

6.1 Testing

Software testing is a critical element of software quality assurance and represents the

ultimate review of specification, design and coding. Software testing fundamentals define the

overriding objectives for software testing. Testing is one of the steps in the software

engineering process that could be viewed (psychologically, at last) as destructive rather than

constructive.

6.1.1 Test Plan

The importance of software testing and its implications cannot be overemphasized.

Software testing is a critical element of Software Quality Assurance and represents the

ultimate review of the specifications, design and coding.

6.1.2 Testing Objectives

Testing is the exposure of the system to trial to see whether it produces correct output.

Testing is a process of executing program with intent of finding an error. A good test case is

one that has a high probability of finding a yet undiscovered error. In a word, tests are

designed systematically so that they uncover different classes of errors and do so with a

minimum time and effort.

If testing is conducted successfully, it will uncover errors in the software. As a

secondary benefit, testing demonstrate that software functions appear to be working

according to specifications made by customer. It is important to keep in mind that, software

testing cannot show the absence of defects, and rather it shows the error present in the

software.


52/69


TECHNOLOGY



6.2 Testing Strategies

A strategy for software testing integrates software. Test case design techniques into wellplanned series that results in successful construction of software.

6.2.1 Unit Test

Unit testing focuses verification effort on the smaller unit of software designs the

module. Important control paths are tested to uncover errors within the boundary of the

module. The relative complexity of tests and errors deleted as a result is limited by the

constrained. The local data structure is examined to ensure that data stored temporarily

maintains its integrity during all steps in an algorithms execution. Boundary conditions are

tested to ensure that module operates properly at boundaries. All independent paths though

the control structure are exercised to ensure that all statements in a module have been

executed at least once. All error-handling paths are tested. Testing is done for the incorrect

variable names, data types, under flow, overflow etc.

6.2.2 Integration Test

Integration testing is a systematic technique for constructing the program structure

while the same time conducting tests to uncover errors associated with interfacing.

The objective is to take unit tested module and build a program structure that has

been dedicated by design. All the modules are combined in advance. The entire program is

tested as a whole.

6.2.3 Validation Test

At the culmination of integration testing, software is completely assembled as a

package, interfacing errors have been uncovered and corrected and a final series of software

tests validation may begin.


53/69


TECHNOLOGY



Software validation was achieved through a series of black box test that

demonstrates conformity with the requirements. Validation test was succeeded because the

software functions in the manner that can be reasonably expected by the customer.

6.4.2 System Test

System testing is actually a series of difficult test whose primary purpose is to fully

exercise the computer based system. Include Recovery Testing during crashes.

6.3 Test case design

6.3.1 While-Box Testing (Glass-box testing)

White-box tests focus on the program control structures. Test cases are derived to

ensure that all statements in the program have been executed at least once during testing and

that all logical conditions have been exercised.

Knowing the internal working of the product, tests can be conducted to ensure that all

gears mesh that is internally operations performs according to specification and all internal

components have been adequately exercised.

White Box testing is a case design method that uses the control structure of the

procedural design to derive test cases. Using white box testing methods, the test cases should

be guaranteed that all independent paths within a module have been considered at last once.

Exercise all logical decisions on their true and false sides.

Execute all loops at their boundaries and within their operational bounds.

Exercise internal data structures to ensure their validity.


54/69


TECHNOLOGY



6.3.2 Black-Box Testing

Black-box testing focuses on the functional requirements of the software. It is not an

alternative to White-box technique. Rather it is compulsory approach that is likely to uncover

a different class of errors than white-box methods.

Black-box testing attempts to find following types of errors

Incorrect or missing functions.

Interface errors.

Errors in data structures or external database access.

Performance errors and

Initialization and termination errors.

6.4 Testing/Performance Analysis

The application will be tested on Personal computers. The following tables

will be created to analyze and the performance of these tables will be analyzed.

6.5 Test Cases

Following are some of the important test cases and expected outcomes as per the testing plan.

One to One Message sending.

One to Many Message sending.

Many to One Message sending.

Many to Many Message sending.
