Introduction and Background
AtLink Communications is the leading provider of Voice Process Automation technology. By treating Voice Processes the same as a standard Business Process, AtLink customers automate, manage and control their enterprise more effectively and efficiently than previously possible. Currently, AtLink EVI (Enterprise Voice Integration) needs SMS (Short Message Service) module to accommodate the immediate and future requirements of customers. Therefore, AtLink has sponsored for team 6 of UH Clear Lake to develop this module.
This project aims to develop SMS web-based application which supports two-way SMS over the United States and Europe using SMTP, HTTP and SMPP protocols. In particular, the application can change the binding to any gateway by changing binding parameters and integrate with existing EVI Communication profiles. SMS messages are routed through commercial SMS gateways. The application can select the optimal gateway for a SMS message in real time and bind the input parameters accordingly. It is also can be integrated with the profiles of EVI Communications. It has been developed by using AJAX for UI, JAVA as a development language and Eclipse as a development environment and Microsoft Visio as an UML tool for analysis & design specifications. The rest of this document will be organized as follows:
- Design and Implementation: This part introduces about the requirements, architecture, the Use Case diagram, relation schema, class diagram, technologies used, software development model and implementation issues of the application.
- Evaluation of solution: This part tells about the solution by using Prototype evaluation and the lessons learned from this project.
- Conclusion and Future directions: Conclude about project and its future directions.
- References: List the sources of references.
- Appendices: Provide background information on how SMS system works; the screenshot of our application and the criteria for evaluating a SMS gateway provider and SMS Gateway Provider Research.
In conclusion, the team has successfully tested the application to send and receive messages using HTTP, SMTP in the real environment and SMPP in the simulation environment.
Design and Implementation
1 System Architecture
Figure 1 is the system architecture. The components developed by team members are in the rectangular with dash line:
[pic]
Figure 1 SMS Spot Application Architecture
The application contains seven main components. Its functions are described as follows:
- Web Browser: Running on client-side, it allows users log in and send SMS messages.
- Web Service: Provide the service for gateway and SMS application to send and receive SMS messages under JAXWS
- EVI (Enterprise Voice Integration) profile: contain the information of customers. Based on this information, the web application can determine the route and protocol for transferring a message.
- Web Application: Running in the server-side, it handles requests from SMS users for sending and receiving SMS message. Beside, the web application can get the information from EVI profile or database, and then it decides the route and the protocol that it uses to send the SMS message. This is the server side component to be built by the project.
- SMS Gateway: an SMS gateway can be set up to handle the connections to the SMSCs. To connect to an SMS gateway, you can use an SMSC protocol such as SMPP, HTTP/HTTPS, email to SMS, etc.
- SMS Center: A SMS center (SMSC) is responsible for handling the SMS operations of a wireless network. When an SMS message is sent from a mobile phone, it will reach an SMS center first. The SMS center then forwards the SMS message towards the destination.
- Mail Sever: Provide SMTP service to send SMS messages to the mail system of the mobile phone carriers and a mailbox to receive the SMS message sent from mobile phones.
2 Use Case Diagram
The following is the Use Case diagram of the application. It contains three actors which are User, Administrator and Mobile and the functions performed by these actors. The functions that will be performed by User are:
- Register
- Login
- Create Profile
- Send SMS message
- Reply SMS message
The functions that will be performed by Administrator are:
- Login
- Create User
- Manage User
- Configure System
- Manage SMS Gateway Account

3 Relation Schema
The Database includes four tables to provide complete information to users and they are stored in MySQL database management system.
- Message table: is identified by MessageID and contains information such as messagetype, subject, content, sender, date and userID. This table is used to store all the messages sent back and forth by users
- Contact table is identified by UserID and contains information such as Username, password, firstname, lastname, address, homephone, cellphone and servprovider. This table is used to store the contact or recipient information that user want to send messages to.
- Group table is identified by userID, groupID and contains information such as group name, description. This table is used to store group of contact or recipient information that user want to send messages to.
- GroupDetail table is identified by userID, groupID. This table is used to provide detail information of the corresponding group.
4 Class Diagram
A complete class diagram is included as Appendix E.
5 Technologies Used
The application has been developed by using AJAX for UI, JAVA as a development language and Eclipse as a development environment and Microsoft Visio as an UML tool for analysis & design specifications. Especially, we exported every functions of the applications into Web services using JAXWS, which would be much easier for AtLink to develop other new functions or change the user interfaces when needed.
6 Software Development Model
We used an iterative approach to development in concert with rapid prototyping. After collecting requirements we started by developing the required functions and user interfaces and showed them to Mr. Dilhar to give him idea of what the application would look like and also helped us to refine the requirements by communicating in terms of the proposed user interfaces. Through the discussion, we received feedback from Mr. Dilhar to make all necessary changes to the application to provide needed features.
7 Implementation Issues
The main obstacles we encountered were the limited time and budget. Therefore, we used the Logica SMSC simulation software to do the programming with SMPP protocol. Even though this is a simulation SMSC but it works almost the same as the real SMSC. Therefore, we can assure that when AtLink Communications Inc. buys enough credits to use the real SMSCs, the application is not required to change the code. The only thing that needs to be changed is the suitable parameters for that SMSC provided by the SMS gateway providers. This minor change is accepted by the mentor from AtLink Communications Inc., Mr. Dilhar De Silva, CTO of AtLink Communication Inc.
Evaluation of Solution
1 Prototype Evaluation
We have developed successfully SMS application that satisfies all the requirements of AtLink Communication Inc. During almost four months, we had to work hard to:
- Make clear the requirements from AtLink Communication Inc.
- Do the research on SMS technologies in details.
- Choose suitable SMS gateways for the application.
- Learn how to use tools in design and develop the application.
The result of our hard work is to deliver a user friendly, flexible to deploy and add new features and easy to maintain SMS application which is able to
- Connect to any SMTP, HTTP and SMPP SMS gateways
- Change the binding dynamically to any gateway by changing binding parameters
- Support two-way SMS capabilities. It means that the application can send message to mobile phone and receive message from mobile phone.
- Cover United State and Europe
- Integrate with EVI Communication profiles.
Besides, we spent many hours to analyze the user actions when they use this application to create the most fancy and convenient user interfaces and optimizing the page flow and information displayed to the user.
2 Lessons learned
This project was rather new to us in term of technologies and tools used to develop the application. However, with the help of our instructor Dr. Yue and mentor Mr. Dilhar, we have developed successfully the SMS application and we learned the following lessons:
- How to do the research and choose appropriate SMS gateway providers: We spent so much time to search for SMS gateway providers and created a list of criteria to decide which providers are suitable for our application. In the future, we can use this technique to choose similar products or services
- Requirement Engineering: The requirements provided to us were in very high level. However, with our prototype and test cases shown to our mentor Mr. Dilhar we could capture the requirements and clearly defined the scope for the application. Moreover, we get to know that we should think as customers to develop the application.
- Project and Team Management: Even though we are good friends but each team member has his own strength and weakness and especially they had different schedule. Therefore, managing such team is a quite difficult task. We had to clearly divide tasks and assigned to appropriate team members, the team leader had to co-ordinate the team members, contacted with instructor Dr. Yue and mentor Mr. Dilhar, tracked progress and resolved the conflicts in the team.
We believe that, these lessons will be valuable experiences for us in the future not only in developing application but also in many cases of real life.
Conclusions and future direction
The SMS Spot application has been developed to allow users to send and receive SMS messages. The application uses two SMS gateways which are ClickaTell SMS Gateway for SMTP and HTTP/HTTPS protocols and Logica simulation gateway for SMPP protocol. It can send and receive messages to and from mobile phone.
The application meets all the requirements required by AtLink Inc. However, to deploy application, Atlink Inc. needs to buy enough credit to use SMPP protocol. We believe that, with the real SMS gateway, the application will required a little or no modification to send and receive SMS message.
In the future, the application can be added more services such as send/receive Voice messages, Ring tone and pictures to mobile phone or do a schedule tasks or services based on the users’ requirements.
We would like to thank to Dr. Yue and Mr. Dilhar for their advices to help us complete this project successfully.

3 Appendix C – How SMS system works
SMS stands for Short Message Service which has achieved huge success in the wireless world. Billions of SMS messages are sent every day. SMS is now a major revenue generator for wireless carriers. A lot of innovative applications are now built on top of the SMS technology and more are being developed. The following is a diagram of a typical SMS system.
[pic]
Figure 3 Typical SMS system
Figure 1 shows a typical SMS system. The SMS center (SMSC) serves as the bridge for mobile phones to the external world by routing the SMS messages. The SMS gateways, mostly commercial in nature, route SMS messages between the SMSC, and between SMSC and the Internet world. As a result, SMS applications developed using Internet Protocol, such as SMTP, HTTP and SMPP, need only to route SMS messages to the appropriate SMS gateways.

6 Appendix F – SMS Gateway Provider Research
Based on the requirement of the project, we first pick up the providers that satisfy the requirement of the project on this step. That means the providers have to support HTTP and SMTP API and 2-way SMS messaging in US with an appropriate price. We firstly evaluate each provider by four criteria: cost, coverage, protocols and 2-way SMS messaging.
Step 1: Collecting provider’s information

f. Shortcode
▪ All shortcodes in the USA are obtained through a central body. This body charges a monthly rental fee, which is included in the above pricing.
▪ With Clickatell, if you have already obtained your own shortcode, then you may qualify for a monthly discount of $480 for a random shortcode, or $950 for a selected shortcode.
▪ With other providers, we don’t find the information about shortcode. You should contact with their staff to get this information.

Step 4: Chosen SMS Gateway provider
We will eliminate some providers in this step based on the information that we analyze above.
|Provider |Status |
|air2web |Waiting |
|clickatell |Chosen |
|sms2email |Chosen |
|mysmsaddress |Eliminated |
|mxtelecom |Chosen |
Table 14 Chosen SMS Gateway providers
Note:
▪ Air2Web is eliminated because we have no information about the price of their service. We are trying to contact with Air2Web to find more information about them and hope that we can find one more appropriate provider for our project
▪ MySMSAdress is eliminated because they require buying so many credits and messages for the minimum purchase.
Step 5: Choose SMS Gateway provider
Finally, we think Clickatell, SMS2Email, and MXTelecom are the most appropriate with this project.
Note : Major US wireless carriers
The major US wireless carriers (Alltel, Cingular, Nextel, Skytel, Sprint, T-Mobile and Verizon) don’t provide the services that allow accessing their SMPP gateway. The information in their website doesn’t state that they support SMPP connection. They only support HTTP, SMS to email and email to SMS. Our application can use the protocols that they support to send and receive messages.
