  2. UWI Pilots mCommunity Skills Bank • President of Claxton Bay Community Council expressed interest in his community becoming more productive and drawing on its own resources • Envisioned a paper-based Skills Bank • UWI proposed an SMS-based mCommunity Skills Bank to provide wide access for all in the community ECNG SMS • The Department of Electrical and Computer Engineering has developed a Student Messaging Service (SMS) to facilitate access to key scheduling information • This service is particularly useful to the many students who do not have Internet access and need, for example, to query exam timetable information from off-campus homes

  3. Mobile Messaging System Host Computer Mobile Application (PHP) Database (MySQL) GSM Mobile Phone Communication Utility (Gnokii) GSM Modem Driver USB/Bluetooth/Infrared Connection GSM Mobile Phone Incoming SMS Outgoing SMS

  4. System Flowchart START New SMS in database outbox? New SMS on phone? No No Yes Yes Write SMS to database inbox Send SMS through phone New SMS in database inbox? Process SMS Write response SMS to database outbox No Yes

  5. ECNG SMS - Operation Student request for timetable information: “lecture ecng3001” or “L3001” System Response: ECNG3001 Thu 10:10am-12:00pm RM 7 Fri 10:10am-11:00am RM 5.1 Course Day Time Room

  8. Advantages • Accessible to all mobile users as SMS capability is standard on all contemporary mobile phones • Available 24 hours a day and practically throughout the globe, of course, with the appropriate roaming and interconnection agreements in place • Relatively inexpensive to implement • Lower service cost than applications implemented through a commercial SMS gateway provider

  9. Disadvantages • Use of a regular mobile phone number which is not as easy to remember as a short code such as 1234 • Low sending rate. A GSM mobile phone can typically send 6-10 SMS messages per minute • Only appropriate for relatively small amounts of information. The maximum size of an SMS message is 160 characters • Mobile user must have knowledge of the appropriate message format to use

  10. Observations • Extended User Community • Database can be accessed via SMS and the Internet • Commercial enterprises access via Internet while community members access via SMS • Implementation Issues • Technology Constraints (Session-based: USSD) • Service Costs • Developing and deploying a low traffic information retrieval system using mobile SMS can be done relatively quickly and inexpensively • As for all SMS-based applications, simple and intuitive message formats are required

  11. Observations • The SMS message format and the amount of information involved will determine how complex your application is in terms of how it processes incoming SMS messages and generates outgoing SMS responses • Migrating to full Mobile Internet implementations of these types of applications is straightforward but not as imminent as handset and service costs limit uptake among Caribbean poor • A full Mobile Internet implementation has the potential as an m-Government service
